Vous pouvez toutefois vous reporter à ceux du téléphone IP Cisco Unified série 7900 pour y découvrir la présentation des fonctions et des fonctionnalités courantes de votre téléphone. Informations relatives à la sécurité et aux performances Cette section décrit l’effet des pannes d’électricité et des autres périphériques sur votre téléphone IP Cisco Unified. Panne d’électricité Vous ne pouvez accéder au service d’urgence que si votre téléphone est alimenté. Si l’alimentation est interrompue, le service d’appel d’urgence et de réparation est indisponible pendant toute la durée de la coupure. Il se peut que vous deviez ensuite réinitialiser ou reconfigurer votre téléphone pour pouvoir utiliser le service d’appel d’urgence et de réparation. Utilisation de périphériques externes Les informations suivantes s’appliquent lorsque vous utilisez des périphériques externes avec le téléphone IP Cisco Unified. Cisco recommande d’utiliser des périphériques externes (casques, etc.) de bonne qualité et protégés des interférences produites par les signaux de fréquences radio et audio. Selon la qualité de ces périphériques et leur proximité par rapport à d’autres périphériques, tels que des téléphones portables ou des radios bidirectionnelles, des parasites sonores peuvent toujours se produire. Dans ce cas, Cisco vous recommande d’effectuer une ou plusieurs des opérations suivantes : • Éloignez le périphérique externe de la source émettrice des signaux de fréquences radio ou audio. • Maintenez les câbles du périphérique externe éloignés de la source émettrice des signaux de fréquences radio ou audio. • Utilisez des câbles blindés pour le périphérique externe ou des câbles dotés d’un blindage supérieur et d’un meilleur connecteur. • Raccourcissez le câble du périphérique externe. • Utilisez des structures en ferrite ou d’autres dispositifs de ce type pour les câbles du périphérique externe. La société Cisco ne peut garantir les performances du système car elle ne dispose d’aucun moyen de contrôle sur la qualité des périphériques externes, des câbles et des connecteurs utilisés. Le système fonctionne comme il convient lorsque les périphériques appropriés sont connectés à l’aide de câbles et de connecteurs de bonne qualité. 4 OL-17124-01 Avertissement Dans les pays de l’Union européenne, utilisez uniquement des casques externes conformes à la Directive [89/336/CE] sur la compatibilité électromagnétique (CEM).

La fourniture de produits cryptographiques Cisco n’autorise pas un tiers à importer, exporter, distribuer ou utiliser le chiffrement. Les importateurs, exportateurs, distributeurs et utilisateurs sont responsables du respect des lois américaines et des autres pays. Si vous utilisez ce produit, vous vous engagez à respecter les lois et réglementations applicables. Si vous n’êtes pas en mesure de respecter les lois américaines et des autres pays, renvoyez-nous ce produit immédiatement.

Si ce n’est pas le cas, reportez-vous à l’illustration et au tableau ci-dessous pour raccorder le téléphone. 1 Port de l’adaptateur CC (48 V) 6 Prise du combiné 2 Alimentation CA vers CC 7 Prise du casque 3 Cordon d’alimentation CA 8 Bouton du socle 4 Port réseau (10/100 SW) 9 Prise auxiliaire (AUX) 5 Port d’accès (10/100 PC) AUX DC48V 10/100 SW 10/100 PC + 185045 2 9 8 3 4 5 6 7 1 6 OL-17124-01 Réglage du socle Pour modifier l’angle de la base de votre téléphone, maintenez le bouton du socle enfoncé pendant que vous réglez le socle. Réglage du support du combiné Cisco recommande de régler le support du combiné, notamment lors du montage mural du téléphone. Cette opération évite que le récepteur ne glisse facilement de son support. Reportez-vous au tableau ci-dessous pour obtenir les instructions correspondantes. Enregistrement à l’aide de l’outil TAPS Une fois votre téléphone raccordé au réseau, votre administrateur système peut vous demander d’enregistrer automatiquement votre téléphone à l’aide de l’outil TAPS (Tool for Auto-Registered Phones Support, Outil d’assistance des téléphones enregistrés automatiquement). L’outil TAPS peut être utilisé aussi bien pour un nouveau téléphone que pour remplacer un téléphone existant. Pour enregistrer un téléphone à l’aide de l’outil TAPS, décrochez le combiné, saisissez le numéro de poste TAPS fourni par votre administrateur système et suivez les instructions vocales. Il se peut que vous ayez à saisir la totalité de votre numéro de poste, y compris l’indicatif régional. Lorsque votre téléphone affiche un message de confirmation, raccrochez. Le processus de redémarrage du téléphone est lancé. 1 Posez le combiné sur le côté et tirez vers le haut la plaquette en plastique carrée du support du combiné. 2 Faites pivoter la plaquette de 180 degrés. 3 Pour remettre la plaquette en place sur le support du combiné, faites-la coulisser. Une extension ressort en haut de la plaquette qui a pivoté. Replacez le combiné sur son support. 1 2 3 120521 Raccordement du téléphone Manuel des téléphones IP Cisco Unified 7962G et 7942G pour Cisco Unified Communications Manager 7.0 (SCCP et SIP) 7 Utilisation d’un casque Vous pouvez utiliser un casque filaire ou un casque sans fil fonctionnant avec la fonction de contrôle à distance du clip de commutation pour casque sans fil. Prise en charge du casque Bien que Cisco Systems réalise certains essais internes sur des casques de fournisseurs tiers utilisés avec les téléphones IP Cisco Unified, Cisco ne certifie pas ni ne promeut de produits de fournisseurs de casques ou de combinés. Cisco recommande d’utiliser des périphériques externes de bonne qualité, par exemple des casques blindés contre les interférences produites par les signaux de fréquences radio (RF) ou audio (AF). En fonction de la qualité de ces périphériques et de leur proximité par rapport à d’autres appareils, tels que les téléphones portables et les radios bidirectionnelles, des parasites sonores ou des échos peuvent toujours se produire. Un ronflement ou un bourdonnement peut être entendu soit par l’interlocuteur uniquement, soit par l’interlocuteur et par l’utilisateur du téléphone IP Cisco Unified. Les ronflements et les bourdonnements peuvent être provoqués par diverses sources extérieures : lampes électriques, moteurs électriques ou grands écrans d’ordinateur, par exemple. Pour plus d’informations, reportez-vous à Utilisation de périphériques externes, page 3. Remarque Dans certains cas, il est possible de réduire ou d’éliminer le ronflement à l’aide d’un groupe amplificateur de puissance local ou d’un injecteur de puissance. En raison des contraintes environnementales et matérielles liées aux différents sites de déploiement des téléphones IP Cisco Unified, il n’existe pas de solution de casque unique optimale pour tous les environnements. Cisco recommande aux clients de tester les casques dans l’environnement prévu afin de déterminer leurs performances avant de prendre une décision d’achat et de les déployer en masse. Qualité audio à l’appréciation de l’utilisateur Au-delà des performances physiques, mécaniques et techniques, la qualité sonore d’un casque doit sembler bonne à l’utilisateur et à son interlocuteur. La qualité sonore est subjective et Cisco ne peut garantir les performances d’aucun casque. Toutefois, un certain nombre de casques de grands fabricants de casques ont été signalés comme fonctionnant bien avec les téléphones IP Cisco Unified. Reportez-vous aux sites des fabricants pour en savoir plus.

Suivi des appels suspects Si vous faites l’objet d’appels suspects ou malveillants, votre administrateur système peut ajouter la fonction d’identification des appels malveillants (IDAM) à votre téléphone. Cette fonction permet d’identifier un appel actif comme suspect, ce qui lance une série de messages automatiques de suivi et de notification. Donner la priorité aux appels critiques (uniquement sur les téléphones SCCP) Dans certains environnements spécialisés, tels que les bureaux de l’Armée ou de l’État, il se peut que vous ayez besoin de passer et de recevoir des appels urgents ou critiques. Si vous avez besoin de ce traitement spécialisé des appels, votre administrateur système peut ajouter une fonction de préséance et préemption à plusieurs niveaux (MLPP) sur votre téléphone. Vérifier que le téléphone à l’autre extrémité de la connexion est également sécurisé Regardez si l’icône de chiffrement en forme de verrou apparaît et écoutez si une tonalité de sécurité retentit au début de l’appel. Lorsque la fonction d’appel chiffré est configurée sur votre téléphone, l’icône en forme de verrou s’affiche. Toutefois, la conversation est protégée seulement à partir du moment où la tonalité de sécurité retentit au début d’un appel, indiquant que celui-ci est protégé aux deux extrémités. Si votre appel est connecté à un téléphone non protégé, la tonalité de sécurité ne retentit pas. Déterminer s’il est possible de passer des appels sécurisés au sein de votre société Contactez votre administrateur système. Pour... Procédez comme suit : Informer votre administrateur système d’un appel suspect ou malveillant Appuyez sur IDAM ou sur l’option Identification d’appel malveillant.

OL-17124-01 A - 1 CCNA 1-4 v 3.0 – Glossary Copyright  2003, Cisco Systems, Inc. CCNA Glossary A Term Definition A&B bit signaling Procedure used in T1 transmission facilities in which each of the 24 T1 subchannels devotes one bit of every sixth frame to the carrying of supervisory signaling information. Also called 24th channel signaling. AAL ATM adaptation layer. Service-dependent sublayer of the data link layer. The AAL accepts data from different applications and presents it to the ATM layer in the form of 48-byte ATM payload segments. AALs consist of two sublayers, CS and SAR. AALs differ on the basis of the source-destination timing used, whether they use CBR or VBR, and whether they are used for connection-oriented or connectionless mode data transfer. At present, the four types of AAL recommended by the ITU-T are AAL1, AAL2, AAL3/4, and AAL5. See AAL1, AAL2, AAL3/4, AAL5, CS, and SAR. See also ATM and ATM layer. AAL1 ATM adaptation layer 1. One of four AALs recommended by the ITU-T. AAL1 is used for connection-oriented, delay-sensitive services requiring constant bit rates, such as uncompressed video and other isochronous traffic. See also AAL. AAL2 ATM adaptation layer 2. One of four AALs recommended by the ITU-T. AAL2 is used for connection-oriented services that support a variable bit rate, such as some isochronous video and voice traffic. See also AAL. AAL3/4 ATM adaptation layer 3/4. One of four AALs (merged from two initially distinct adaptation layers) recommended by the ITU-T. AAL3/4 supports both connectionless and connection-oriented links, but is primarily used for the transmission of SMDS packets over ATM networks. See also AAL. AAL5 ATM adaptation layer 5. One of four AALs recommended by the ITU-T. AAL5 supports connection-oriented, VBR services, and is used predominantly for the transfer of classical IP over ATM and LANE traffic. AAL5 uses SEAL and is the least complex of the current AAL recommendations. It offers low bandwidth overhead and simpler processing requirements in exchange for reduced bandwidth capacity and error-recovery capability. See also AAL and SEAL. A - 2 CCNA 1-4 v 3.0 – Glossary Copyright  2003, Cisco Systems, Inc. AARP AppleTalk Address Resolution Protocol. Protocol in the AppleTalk protocol stack that maps a data-link address to a network address. AARP probe packets Packets transmitted by AARP that determine if a randomly selected node ID is being used by another node in a nonextended AppleTalk network. If the node ID is not being used, the sending node uses that node ID. If the node ID is being used, the sending node chooses a different ID and sends more AARP probe packets. See also AARP. ABM Asynchronous Balanced Mode. An HDLC (and derivative protocol) communication mode supporting peer-oriented, pointto-point communications between two stations, where either station can initiate transmission. ABR 1) available bit rate. QOS class defined by the ATM Forum for ATM networks. ABR is used for connections that do not require timing relationships between source and destination. ABR provides no guarantees in terms of cell loss or delay, providing only best-effort service. Traffic sources adjust their transmission rate in response to information they receive describing the status of the network and its capability to successfully deliver data. Compare with CBR, UBR, and VBR. 2) area border router. Router located on the border of one or more OSPF areas that connects those areas to the backbone network. ABRs are considered members of both the OSPF backbone and the attached areas. They therefore maintain routing tables describing both the backbone topology and the topology of the other areas.

See also ring monitor and standby monitor. adapter See NIC (network interface card). adaptive differential pulse code modulation See ADPCM. adaptive routing See dynamic routing. A - 4 CCNA 1-4 v 3.0 – Glossary Copyright  2003, Cisco Systems, Inc. ADCCP Advanced Data Communications Control Protocol. An ANSI standard bit-oriented data link control protocol. address Data structure or logical convention used to identify a unique entity, such as a particular process or network device. addressed call mode Mode that permits control signals and commands to establish and terminate calls in V.25bis. See also V.25bis address mapping Technique that allows different protocols to interoperate by translating addresses from one format to another. For example, when routing IP over X.25, the IP addresses must be mapped to the X.25 addresses so that the IP packets can be transmitted by the X.25 network. See also address resolution. address mask Bit combination used to describe which portion of an address refers to the network or subnet and which part refers to the host. Sometimes referred to simply as mask. See also subnet mask. address resolution Generally, a method for resolving differences between computer addressing schemes. Address resolution usually specifies a method for mapping network layer (Layer 3) addresses to data link layer (Layer 2) addresses. See also address mapping. Address Resolution Protocol See ARP. address translation gateway See ATG. adjacency Relationship formed between selected neighboring routers and end nodes for the purpose of exchanging routing information. Adjacency is based upon the use of a common media segment. adjacent nodes 1) In SNA, nodes that are connected to a given node with no intervening nodes. 2) In DECnet and OSI, nodes that share a common network segment (in Ethernet, FDDI, or Token Ring networks). administrative distance A rating of the trustworthiness of a routing information source. In Cisco routers, administrative distance is expressed as a numerical value between 0 and 255. The higher the value, the lower the trustworthiness rating. admission control See traffic policing.

PIM is unicast routing protocol independent and can be operated in two modes: dense mode and sparse mode. See also PIM dense mode and PIM sparse mode. PIM dense mode One of the two PIM operational modes. PIM dense mode is data-driven and resembles typical multicast routing protocols. Packets are forwarded on all outgoing interfaces until pruning and truncation occurs. In dense mode, receivers are densely populated, and it is assumed that the downstream networks want to receive and will probably use the datagrams that are forwarded to them. The cost of using dense mode is its default flooding behavior. Sometimes called dense mode PIM or PIM DM. Contrast with PIM sparse mode. See also PIM. PIM DM See PIM dense mode. PIM SM See PIM sparse mode. P - 121 CCNA 1-4 v 3.0 – Glossary Copyright  2003, Cisco Systems, Inc. PIM sparse mode One of the two PIM operational modes. PIM sparse mode tries to constrain data distribution so that a minimal number of routers in the network receive it. Packets are sent only if they are explicitly requested at the RP (rendezvous point). In sparse mode, receivers are widely distributed, and the assumption is that downstream networks will not necessarily use the datagrams that are sent to them. The cost of using sparse mode is its reliance on the periodic refreshing of explicit join messages and its need for RPs. Sometimes called sparse mode PIM or PIM SM. Contrast with PIM dense mode. See also PIM and RP (rendezvous point). pin location A color-coded slot on a patch panel.

Chaque commutateur de cette gamme a un faible encombrement (1 unité de rack) les rendant très facile à installer sur un bureau ou dans un local technique (Figure 1). Figure 1: Gamme de commutateurs Catalyst 2950 Débit à la vitesse du médium des stations d'extrémité connectées sur le LAN Avec une matrice de commutation de 13,6 Gigabits par secondes (Gb/s) et une bande passante maximale de transfert de 10,1 millions de paquets par seconde (paquets de 64 octets), le Catalyst 2950 délivre sur tous les ports un débit à la vitesse du médium. Le commutateur Catalyst 2950 supporte des fonctions augmentant les performances tel que le Fast EtherChannel®, le Gigabit EtherChannel et le 802.3ad, offrant jusqu’à 4Gb/s de bande passante entre commutateurs, routeurs et serveurs en agrégeant les liens Ethernet, Fast Ethernet et Gigabit Ethernet entre eux et en répartissant la charge par sessions entre les équipements. Migrer vers le Gigabit sur le LAN Les entreprises de taille moyenne qui ont une infrastructure de câblage réseau existante en cuivre (Categorie 5, UTP) ont maintenant la possibilité de migrer leurs LANs en Gigabit Ethernet. Le Catalyst 2950T-24 est doté de deux ports fixes hauts débits 10/100/1000BaseT (Gigabit sur cuivre) en plus des 24 ports 10/100 pour connecter les postes de travail. Pour un prix au port légèrement supérieur, les entreprises de taille moyenne peuvent maintenant faire évoluer leurs LANs en Gigabit Ethernet, ou bien connecter des serveurs en Gigabit sur les mêmes commutateurs que les stations de travail. Combiné avec le nouveau Catalyst 3550-12T Gigabit Ethernet multi-niveaux (2/3&4), le Catalyst 2950T-24 offre une solution Gigabit sur cuivre intégrée pour les entreprises de petites et moyennes tailles qui veulent faire évoluer leurs cœurs de réseaux en Fast Ethernet vers le Gigabit, et qui veulent Cisco Systems, Inc.

Pour de plus longues distances, la remontée vers le cœur de réseau en fibre est toujours la meilleure des solutions. Différences entre les logiciels Cisco IOS Standard (SI) et Enhanced (EI) Image Les commutateurs Catalyst 2950 existent avec deux versions différentes de logiciel Cisco IOS, permettant ainsi de couvrir les besoins en fonctionnalités des petites, moyennes et grandes entreprises à l’extrémité de leur réseau (commutateurs de bureau). La version SI offre les fonctionnalités Cisco IOS basiques pour des données, de la vidéo et des services voix sur un réseau, soit les fonctionnalités nécessaires pour la plupart des petites et moyennes entreprises en France. Pour des administrateurs réseaux et pour des responsables informatiques ayant compris tout l’intérêt de sécurité encore plus avancée, de qualité de service encore plus précise et efficace, et de haute disponibilité du réseau, la version EI offre des services de réseaux intelligents comme la gestion sophistiquée du traffic, l’optimisation de la bande passante et le filtrage des utilisateurs et de la sécurité des accès au réseau. Toutes les fonctionnalités présentes dans la version SI le sont également dans la version EI, et, dans toute la suite de ce document, nous mettrons en évidence par le symbole les caractéristiques spécifiques de la version « Standard » SI par rapport à la version « Enhanced » EI. Qualité de Service évoluée La gamme Catalyst 2950 offre une qualité de service (QoS) de périphérie très évoluée, inégalée dans cette catégorie de produits. Tous les commutateurs Catalyst 2950 supportent deux modes de classification. Le premier mode, fondé sur le standard IEEE 802.1p, consiste à reconnaître les flux déjà étiquetés (802.1p) et à les diriger vers les différentes files d’attentes suivant le niveau de service auquel ils ont droit. Dans le second mode, l’administrateur réseau peut re-classifier les flux sur le port d’entrée avec une valeur par défaut (CoS). Dans le cas où une trame arrive sans que le champ CoS ne soit renseigné (trame dite « non taggée »), l’administrateur réseau peut classifier cette trame avec la valeur de la CoS par défaut définie sur ce port. Cette méthode permet donc d’accepter tout client qui n’est pas capable d’affecter lui-même une classe de service à ses paquets. Une fois que les trames ont été classifiées ou re-classifiées en utilisant une des deux méthodes cidessus, elles sont dirigées vers la file d’attente appropriée en sortie. Les Catalyst 2950 supportent quatre files d’attente en sortie, ce qui permet à l’administrateur réseau une plus grande granularité lorsqu’il affecte les priorités aux applications sur le LAN. L’une de ces files possède une priorité absolue face aux trois autres, utilisée pour les applications temps réel telles que la voix. Le WRR (Weighted Round Robin), une autre amélioration significative, permet de prendre en compte l'ordonnancement entre files d'attente de plus basse priorité en leur permettant de n’être jamais bloquées les unes par rapport aux autres. Ces fonctionnalités permettent aux administrateurs d’ordonnancer le trafic stratégique, le trafic temps réel tel que les ERP (Oracle, SAP, ...), la voix (Téléphonie sur IP), etc. par rapport au trafic normal (FTP, SMTP, flux Web, ...). La version de logiciel Cisco IOS EI permet la prise en compte de manière très précise des caractéristiques de niveaux 2, 3 et 4 pour assurer la QoS sur le réseau. Sa configuration en est grandement simplifiée par la fonction «auto-qos » qui est capable de détecter automatiquement un téléphone IP Cisco et de positionner automatiquement toutes les commandes de classification et de mise en file d’attente de sortie nécessaires au traitement de ce type de flux temps réel. Les Catalyst 2950 EI sont capables de classifier, reclassifier, policer (déterminer si le paquet fait partie d’un profil déterminé de flux et prendre des actions sur le paquet suite à cette analyse), marquer et rejeter un paquet avant même d’être mis dans la mémoire partagée du commutateur. La classification des paquets, de cette sorte, fait respecter les règles de policing en se fondant sur les champs de niveaux 2 à 4. Dans la phase de sortie des paquets sur l’interface destinataire, le commutateur EI recourt à de la mise ordonnée en files d’attentes (« scheduling ») afin de déterminer dans quel ordre ces files sont vidées. Les commutateurs Catalyst 2950 sont également capables d’allouer de la bande passante sur Cisco Systems, Inc. Tous les contenus sont protégés par copyright © 2003, Cisco Systems, Inc. Tous droits réservés. Page 4 sur 4 des critères comme l’adresse MAC source ou destination, l’adresse IP source ou destination, et les numéros de ports UDP et TCP, ce qui est nécessaire à la mise en place d’un contrôle de la bande passante pour certains utilisateurs ou certaines applications. Service Multicast avec IGMP Snooping Les commutateurs doivent être capables de commuter les adresses MAC de multicast (dérivées de l’adresse IP du groupe de multicast). La fonctionnalité IGMP Snooping (Internet Group Management Protocol) permet aux commutateurs d’interpréter les requêtes IGMP et d’associer les ports qui doivent recevoir effectivement le flux multicast, même en niveau 2. Un port est ajouté dans la table de commutation, et associé à une adresse MAC de multicast quand un «IGMP Membership report » est reçu sur ce port. Il doit être supprimé de la table de commutation si un message « IGMP Leave » est reçu ou si il n’y a pas de réponse aux requêtes « IGMP Queries ». Pour obtenir des performances exceptionnelles, cette solution implique que le commutateur soit capable de traiter tous le s paquets multicast de niveau 2, ce qui nécessite un matériel spécialisé (ASIC) pour assurer le maintient du débit. Cisco implémente donc IGMP Snooping grâce à une accélération matérielle dédiée sur sa gamme de commutateurs Catalyst 2950. Quant à la configuration de cette fonctionnalité, elle se fait de façon très simple au travers de CMS (Cisco Cluster Management Suite). Mise en grappe de commutateurs Cisco (Cisco Cluster Management Suite) La technologie révolutionnaire de Cisco permet de regrouper jusqu'à 16 commutateurs Catalyst 2950, 3550, 3500 XL, 2900 XL, et 1900 interconnectés, quel que soit leur éloignement géographique, pour former un domaine d'administration IP unique. La technologie ‘Switch Clustering’ supporte une large gamme d'options de connectivité et de configurations fondées sur des standards, offrant ainsi des performances évolutives répondant au plus près à vos besoins. Pour les commutateurs Catalyst 2950, toutes les options de connectivité sont utilisables (d’Ethernet au 802.3ad). N'étant pas limitée par des modules d'empilement et des câbles propriétaires, la technologie Cisco de mise en grappe de commutateurs porte le domaine d'empilement traditionnel au-delà du simple local technique et autorise les connexions de tous types, adaptées à vos besoins spécifiques d'administration, de performances et de coûts. Un commutateur de contrôle, qui peut être un Catalyst 2950, un 3500XL ou un 3550, assure des services de Proxy et de re-routage pour une administration par une adresse IP unique pour chaque grappe. Toutes les commandes d'administration de grappes sont dirigées vers l'adresse IP du commutateur de contrôle. Pour la redondance, il est possible d'attribuer une adresse IP à un deuxième commutateur et de gérer toute la grappe à l'aide d'une seule adresse IP virtuelle. Si le commutateur principal de contrôle tombe en panne, le commutateur de contrôle secondaire ou de secours prend en charge la gestion de la grappe de manière transparente. La mise en grappe de commutateurs Cisco est accessible via la suite CMS (Cisco Cluster Management Suite), une interface d'administration Web gratuite. Elle permet aux administrateurs de réseau de configurer, de surveiller et de gérer un commutateur depuis tout point du réseau par l'intermédiaire d'un navigateur standard tel que Microsoft Internet Explorer ou Netscape Navigator. Il leu suffit de pointer leur navigateur sur l'adresse IP du commutateur de contrôle de la grappe pour accéder à toutes les fonctions d'administration et à 100% des commandes en lignes du logiciel Cisco IOS, regroupant la configuration et le contrôle des ports, la configuration des VLAN, et l'affichage de clichés du réseau. Cette administration Web fait partie intégrante de l'architecture Cisco de regroupement de commutateurs. Elle permet également de déployer les mises à jour logicielles à travers de multiples commutateurs en une seule passe. Toutes ces fonctions sont cependant, pour des raisons de sécurité, désactivables par l’administrateur réseau. Cisco Systems, Inc.

Page 5 sur 5 Sécurité étendue, Administration et fonctions du Cisco IOS intégrés Les commutateurs Cisco Catalyst 2950 sont dotés de plusieurs fonctionnalités exceptionnelles qui améliorent les performances du réseau, son administration et sa sécurité. Les utilisateurs peuvent optimiser la sécurité des données et les performances des réseaux LAN en déployant jusqu'à 64 LANs virtuels (VLAN) par commutateur. Ils ont ainsi l'assurance que les paquets de données sont bien renvoyés uniquement aux stations d'un VLAN donné, créant de ce fait un cloisonnement virtuel entre des groupes de ports sur le réseau et réduisant le volume des transmissions et des broadcasts. Il est possible de créer des liaisons VLAN à partir de n'importe quel port en utilisant le protocole standard 802.1Q. Les VLAN utilisant des protocoles de liaison 802.1Q permettent d'assurer un contrôle plus important, optimisent la sécurité et simplifient les ajouts, les déplacements et les modifications. Les modes PVST+ (Per VLAN Spanning Tree) et 802.1s (Multiple Spanning-Tree Protocol) permettent aux utilisateurs de mettre en oeuvre des liaisons ascendantes redondantes tout en répartissant la charge du trafic sur des liaisons multiples, ce que les mises en oeuvre Spanning Tree standard ne permettent pas. Les technologies Cisco UplinkFast, CrossStack UplinkFast et 802.1w (Rapid Spanning-Tree Protocol) assurent le transfert immédiat vers la liaison ascendante secondaire, et diminuent considérablement (moins de 2 secondes) le temps de convergence de 30 à 60 secondes traditionnellement constaté. Grâce au Catalyst 2950, les administrateurs de réseau peuvent mettre en oeuvre des fonctions de haute sécurité au niveau des ports et de la console. La sécurité sur adresses MAC (Media Access Control) au niveau de chaque port et du commutateur empêche les stations non autorisées d'accéder au réseau ou à l’équipement, de manière statique ou dynamique. La fonction Private VLAN Edge permet d’isoler tous les ports du switch entre eux et d’assurer que tout le trafic entrant par un port ne puisse être dirigé que vers le lien remontant et non vers l’un des autres ports. En outre, une sécurité à niveaux multiples sur l’accès à la console interdit aux utilisateurs non autorisés la modification de la configuration. La fonction d'authentification en RADIUS ou en TACACS+ (Terminal Access Controller Access Control System) permet de centraliser le contrôle d'accès du commutateur et d'empêcher les utilisateurs non autorisés de modifier la configuration. Enfin, la disponibilité du protocole 802.1x permet l’authentification dynamique des utilisateurs sur chaque port. Dans la version logicielle EI des Catalyst 2950, cette authentification en 802.1x des utilisateurs offre également la possibilité d’affecter dynamiquement un VLAN à l’utilisateur, et ceci où qu’il soit sur le réseau. De plus, il est alors possible de positionner des listes de contrôle d’accès (ACL) spécifiques pour chaque utilisateur sur le port sur lequel il a été identifié, ouvrant ainsi la possibilité de gérer la mobilité sur le réseau de manière centralisée et bien plus simplement qu’auparavant. Ces ACLs peuvent également être temporelles et permettre d’offrir des services différents selon la plage horaire, et peuvent aussi filtrer le trafic sur les valeurs du champ DSCP (DiffServ). Tous ces paramètres de contrôle d’accès par port sont effectués en hardware, ce qui garantit qu’il n’y a pas d’impacts de performances lorsqu’ils sont activés. Les Catalyst 2950 EI sont très sécurisés dans leurs capacités d’administration et de configuration car ils supportent SSH (Secure Shell) et SNMPv3 qui permettent de crypter les échanges d’informations en telnet et avec la station d’administration. Enfin, la fonction Private VLAN Edge est accompagnée du Local Proxy ARP pour permettre de minimiser l’impact des broadcasts sur le réseau et d’améliorer la bande passante globale offerte aux utilisateurs. Caractéristiques et avantages Performances exceptionnelles Vitesse maximale du médium, transmission non bloquante sur tous les ports, même sur les ports Gigabit, et sur tous les modèles de la gamme. Matrice de commutation de 8,8 Gbits/s pour les commutateurs en versions de logiciel SI uniquement et 13,6Gbits/s pour les commutateurs en version de Cisco IOS EI. Débits de transfert non bloquants de 1,8 à 10,1 millions de paquets/seconde en fonction du nombre de ports sur le commutateur, assurant des connexions à vitesse maximale sur chaque port.

Qualité de Service (QoS) La reclassification par port permet aux utilisateurs de reclasser les valeurs CoS IEEE 802.1p par port d'où une finesse de contrôle supérieure pour l'implémentation d'une qualité de service à la périphérie du réseau local. Quatre files d'attente par port en sortie traité en Hardware. Le WRR (Weighted Round Robin) permet de prendre en compte l'ordonnancement des files d'attentes de basse priorité. La file d’attente avec une priorité absolue permet de traiter les applications temps réel telles que la voix. Simplicité de déploiement et d'utilisation La technologie Switch Clustering de Cisco permet à un utilisateur de gérer jusqu'à seize commutateurs Catalyst 2950, 3550-12T, 3500 XL, 2900 XL et Catalyst 1900 interconnectés, via une adresse IP unique, quel que soit son emplacement sur le réseau.

Page 7 sur 7 Compatibilité totale entre le Catalyst 2950 et les Catalyst 3500 XL, Catalyst 2900 XL, ou le Catalyst 1900. En utilisant CMS le Catalyst 2950 peut donc etre le commutateur de controle de la grappe. La fonction d'administration logicielle de grappes permet à l'administrateur réseau de déployer les mises à jour à travers un groupe de Catalyst 3550-12T, Catalyst 2950, Catalyst 3500 XL et Catalyst 2900 XL, rapidement et en toute facilité. Sur chaque port, la détection automatique détermine la vitesse de l'équipement connecté et configure le port pour une commutation à 10 ou 100 Mbits/s, facilitant ainsi le déploiement du commutateur en environnements mixtes 10Base-T/100Base-TX. Sur tous les ports, la fonction de négociation automatique sélectionne le mode de transmission (monodirectionnel ou bidirectionnel) afin d'optimiser la bande passante. La configuration par défaut stockée en mémoire flash garantit que le commutateur peut être connecté très rapidement au réseau et transférer le trafic avec une intervention minimale de l'utilisateur. En outre, en cas de panne d'alimentation, la configuration est conservée. Solution de commutation Cisco IOS intégrée Le contrôle, au niveau de chaque port, des tempêtes de broadcast évite que des stations d'extrémité défectueuses ne pénalisent le système. Le support de l'interface de commande en ligne de Cisco IOS® fournit une interface utilisateur et un jeu de commandes commun à tous les commutateurs Catalyst et aux routeurs Cisco. Le protocole CDP (Cisco Discovery Protocol) permet à un poste d'administration de réseaux CiscoWorks de détecter automatiquement tout commutateur dans une topologie de réseau. Facilité d'administration exceptionnelle La technologie Switch Clustering de Cisco permet à un utilisateur de gérer jusqu'à seize commutateurs Catalyst 2950, 3550, 3500 XL, 2900 XL et 1900 interconnectés, via une adresse IP unique, quel que soit son emplacement sur le réseau, avec un navigateur Web standard comme Netscape Navigator ou Microsoft Explorer. Le support des protocoles SNMP (Simple Network Management Protocol) et Telnet assure l'administration globale en bande, et une console d'administration à interface de commande en ligne garantit l'administration hors bande. Pour présenter une interface d'administration commune aux routeurs, commutateurs et concentrateurs Cisco, les commutateurs peuvent être configurés par le logiciel d'administration de réseaux CiscoWorks 2000 ou par CiscoWorks for Windows. L'agent logiciel RMON (Remote MONitoring) intégré supporte quatre groupes RMON (historiques, statistiques, alarmes et événements) pour les fonctions avancées d'administration, de surveillance et d'analyse du trafic. Les neuf groupes RMON sont supportés, via un port SPAN (Switch Port Analyzer) qui permet de contrôler le trafic d'un port unique à partir d'un seul analyseur de réseau ou d'un seul système d'analyse RMON. La fonction d'autoconfiguration facilite le déploiement des commutateurs en paramétrant automatiquement plusieurs unités à travers le réseau à partir d'un serveur d'initialisation.

Page 8 sur 8 des protocoles DNS (Domain Name System), TFTP (Trivial File Transfer Protocol) et NTP (Network Time Protocol) garantit une interopérabilité avec le monde extérieur, tant pour la configuration automatisée que pour la sécurité. STRG (Spanning Tree Root Guard) évite que les périphériques non contrôlés par l'administrateur de réseau ou le fournisseur de services ne deviennent des noeuds racines STP en configurant STRG sur les ports qu'ils contrôlent. BPDU Guard permet de désactiver un port configuré en PortFast lorsqu’il reçoit des BPDU, améliorant ainsi la stabilité et le niveau de sécurité du réseau commuté Sur chaque port, des LED multifonctions fournissent un système d'administration visuel particulièrement pratique sur l'état du port (transfert monodirectionnel ou bidirectionnel, 10BaseT/100Base-TX) et sur l'état du commutateur (système, bloc d'alimentation redondant RPS, utilisation de la bande passante, alimentation en ligne). Sécurité et redondance Support du protocole IEEE 802.1x pour authentifier chaque utilisateur sur une base Radius centralisée et lui autoriser/interdire l’accès au réseau par le port sur lequel il est branché. Le VLAN d’appartenance et les ACLs sont positionnés sur le port La périphérie de VLAN privée assure la sécurité et l'isolation des ports d'un commutateur, garantissant l'acheminement direct du trafic voix de son point d'entrée au périphérique d'agrégation via un chemin virtuel et empêchant son acheminement vers un autre port. La sécurité de type MAC (Media Access Control) au niveau du port empêche les stations non autorisées d'accéder au commutateur. Le mode d'apprentissage d'adresse, spécifié par l'utilisateur, simplifie la configuration et renforce la sécurité. Support du protocole Spanning Tree IEEE 802.1D pour les connexions de réseau fédérateur redondant et les réseaux sans-boucle : simplifie la configuration de réseau et renforce la tolérance aux pannes, {§} avec ses amélioration normalisées 802.1s et 802.1w. Une architecture d'alimentation innovante assure un prix économique et permet aux systèmes Cisco RPS 300 et Cisco RPS 675 de supporter jusqu'à six commutateurs, réduisant le coût d'alimentation redondante par commutateur Pour l'accès à la console, une sécurité à niveaux multiples empêche les utilisateurs non autorisés de modifier la configuration du commutateur. L'authentification TACACS+ contrôle le commutateur de manière centralisée et empêche les utilisateurs non autorisés de modifier la configuration.

バンド回線を敷設するのは、多くの企業にとって負担が大きすぎるでしょう。 また、旧来からバックアップ用のネットワークに利用されてきた ISDN 回 線は、安価に利用できるものの 64 Kbps と低速で、今日ではメイン回線と の速度差があまりにも大きくなってしまい、実用的とはいえません。さらに、 ISDN のデータ通信サービスは、2020 年度後半に終了が予定されています （2016 年 6 月時点）。 そこで、低コストかつ高速なバックアップ回線として広く利用されるように なってきたのが、携帯電話の 4G ネットワークを WAN 接続に利用する「4G LTE ワイヤレス WAN」です。携帯電話キャリアが提供する各サービスによっ て異なりますが、下り（ダウンリンク）最大約 100 Mbps、上り（アップリンク） 最大約 50 Mbps の高速通信を実現します。また、光ファイバ回線よりも低 価格であることに加えて、携帯電話キャリアが提供する定額プランを適用で きるため、バックアップ回線の運用コスト予測が立てやすいというメリットも あります。 ISDN に代わる低コストで高速なバックアップ WAN 回線として バックアップは ISDN から 4G LTE の時代へ 機動性と耐障害性に優れた WAN を実現 特集 Cisco 4G LTE ソリューション シスコのサービス統合型ルータは、携帯電話の 4G LTE ネットワークを使用した WAN 接続に対応しています。 2020 年度後半にデータ通信サービスの終了が予定されている ISDN から 4G LTE ネットワークへと移行することで、 WAN の高速なバックアップ回線を容易に確保できます。また、広範囲をカバーする 4G LTE ネットワークの特徴を 活かして、有線ブロードバンド接続が不可能な環境などで WAN のメイン回線としても活用できます。 バックアップ WAN メイン WAN 通常はメイン WAN の 有線ブロードバンド回線を使用するが、 接続断を検知すると、 バックアップ WAN の 4G LTE ネットワークに切り替える シス コ の サ ー ビ ス 統 合 型 ル ー タ で は、Cisco 819G/GW、Cisco

の連動 デジタル サイネージ スマート シティ スマート トランスポーテーション スマート ロジスティクス スマート ファクトリー 4G LTE ワイヤレス WAN は、バックアップ回線としてだけではなく、物 理的・時間的な制約がある拠点のメイン回線としても有用です。 物理的な制約に対応できる例としては、離島や山間部など、光ファイバ の有線ブロードバンド回線がそもそも提供されていない地域での利用や、 ショッピング モールの通路上の店舗や駅のキオスクなど、スペースの都合 で有線ブロードバンド回線の敷設工事が困難な場所での利用があります。 時間的な制約に対応できる例としては、イベント会場や工事現場の事務 所、または仮設店舗など、限定された期間のみ WAN 回線が必要な場合で の利用があります。 さらに、このように物理的・時間的な制約に強いという特長を敷 ふえん 衍して考 えると、4G LTE ワイヤレス WAN は災害対策としても非常に有用です。東 日本大震災では、シスコは被災地・避難所へエンジニアをボランティアで派 遣し、40 か所以上へ衛星および 3G ワイヤレス WAN 経由のインターネッ ト アクセス環境を展開しました。 また、4G LTE ワイヤレス WAN の最大の特徴は、無線通信の回線であ ることから、ネットワークの構築にケーブルの敷設が不要である点です。し かも、携帯電話の電波を使用することから、かなり広い範囲をカバーするこ とができます。これらの特徴から、4G LTE ワイヤレス WAN は移動拠点の メイン回線としても有用です。 たとえば、内装をホテルのロビーのように改造した車両を「移動営業所」と してさまざまな地域へ走らせ、顧客が株の売買や証券の電子化などを車内 でもできるように、どこに移動しても WAN 接続可能な環境を実現した証券 会社の事例があります。 また、シスコとサンフランシスコ交通局の共同開発で始まった「コネクテッ ド・バス（Connected Bus）」のように、乗客にインターネット接続を提供し つつ、車内のディスプレイで乗り継ぎ情報や周辺の観光情報のようにライブ 情報を提供するなど、これからの都市や公共交通機関で必要とされる先進 的な事例もあります。 物理的・時間的制約がある拠点や移動拠点のメイン WAN 回線として 4G LTE ソリューションの広がる利用シーン インターネット接続を提供 （移動ホット スポット） 車内ディスプレイで ライブ情報を提供 交通局に GPS 情報を送信 車載カメラのリモート制御 バス停に設置された デジタル サイネージと連携

マルチギガビット テクノロジー（mGig） ■「ギガビットを超える無線 LAN」11ac 導入がもたらす有線 LAN の課題 理論値で最大 6.9 Gbps も の 通 信 速 度 を 実 現 する、 超 高 速 無 線 規 格 IEEE 802.11ac。無線 LAN は文字どおり「ギガビット超え」の時代に突入していますが、 11ac への移行が有線 LAN に「古くて新しい」課題をもたらしています。つまり、か つて経験した課題、11a/g から 11n への移行を計画した際と同様の課題です。 11a/g から 11n への移行を計画した際に、アクセス ポイントを収容するアクセス ス イッチがファスト イーサネット（理論値で最大 100 Mbps）ではキャパシティ不足であ ることは明白でした。いま同様に、11n から 11ac への移行を計画する際に、1 ギガ ビット イーサネット（1 GE、理論値で最大 1000 Mbps）ではキャパシティ不足である ことが明白です。具体的には、 ● 複数の 11ac 対応アクセス ポイントを収容するアクセス スイッチのアップリンクが 1 GE では、そこがボトルネックになります。 ● 11ac Wave 2 対応アクセス ポイントを収容するアクセス スイッチのダウンリンク が 1 GE では、そこがボトルネックになります。 したがって、11ac のポテンシャルをフルに発揮させるためには、11a/g から 11n への移行の際と同様に、少なくともアクセス スイッチのリプレースが必須です。 ところが、現行の IEEE 標準規格で 1 GE を上回る規格は、銅線または光ファイバ ケー ブルによる 10 ギガビット イーサネット（10 GE）ですが、10 GE 対応スイッチの導入 にはいくつかの難点があります。 ● 多くの場合、ケーブルの再敷設が必要：全世界の企業で敷設済みの銅線ケーブルの 46 % がカテゴリ 5e、28 % がカテゴリ 6 です。銅線による 10 GE は、カテゴリ 5e には非対応、カテゴリ 6 ではケーブル長 55 m までの制限があります。光ファイ バ ケーブルの敷設はもちろん、銅線ケーブルの敷設にも莫大なコストがかかります。 ● 現行の 10 GE は PoE に非対応：アクセス ポイントに電源設備と電源ケーブルが 必要になるため、電源供給の課題が発生します。 ■ Cisco Catalyst マルチギガビットテクノロジー（mGig） 11ac 導入がもたらすこのような課題を一挙に解決するのが、シスコの革新的な Cisco Catalyst Multigigabit テクノロジー（mGig）です。mGig には大きく分けて、 次の 3 つの特長があります。 ● マルチ スピード：カテゴリ 5e ケーブルで 100 Mbps、1 Gbps、2.5 Gbps、お よび 5 Gbps をサポート、カテゴリ 6a ケーブルで 10 Gbps をサポートします。 ● ケーブル タイプ：カテゴリ 5e、カテゴリ 6、カテゴリ 6a を含む、多様なケーブル タイプをサポートします。 ● PoE：現行の 10 GE とは異なり、PoE（15.4 W）、PoE+（30 W）、および UPOE（60 W）をサポートします。 mGig は、シスコが 2014 年 10 月に設立した NBASE-T アライアンスのテクノロ ジーに基づいています。NBASE-T アライアンスには多数のベンダー企業が参画、現 在、2.5GBASE-T および 5GBASE-T として、IEEE での標準化が進められています。 ■ Cisco Catalyst

として指定されて、その他の AP は管理対象 AP としてマスター AP に関連づけられます。マスター AP はワイヤレス コントローラとして動作して、管理対象 AP を管理および制御するだけでなく、通常の AP と同様にクライアントに無線 LAN 接続も提 供します。管理対象 AP は通常の集中管理型（lightweight）AP として動作して、クライア ントに無線 LAN 接続を提供します。 Cisco Wireless Release 8.3 用 Cisco Mobility Express ソフトウェア Cisco Wireless Release 8.3 では、Cisco Mobility Express ソフトウェアに次の新 機能が導入されています。 ● Cisco CMX Cloud：Cisco Mobility Express と CMX Cloud のシンプルな Web ユーザ インターフェイス（UI）で、ゲスト アクセスおよびプレゼンス分析用の CMX Connect を使用できます。 ● 初期設定ウィザードに自動リダイレクト：ブラウザに IP アドレスを入力しなくても、 Cisco Mobility Express の Web UI にアクセスしてセットアップできます。 ● 内蔵 DHCP サーバ：外部 DHCP サーバは不要です。 ● NTP サーバ プールと OpenDNS：3 つの NTP サーバ プールが自動的に設定されて、 OpenDNS を使用して名前解決されます。 ● Web UI での RF 最適化：Web UI に RF 最適化機能が追加されています。パラメー タは RF 特性の変化に応じて変更できます。 ● Web UI の SNMP v3：Web UI で SNMP v2c/v3 がサポートされています。CLI からも v1 を含めて設定できます。 ● オンライン ソフトウェア更新：ソフトウェアは cisco.com から AP に直接ダウンロード されます。ローカルにダウンロードして解凍したり、TFTP パラメータを設定したりする 必要はありません。 ● Mobility Express Network に AP を自動的に追加：AP は cisco.com からコー ドを自動的にダウンロードしてネットワークに参加します。手動操作は不要です。 ● Mobility Express を強制的にフェールオーバー：Web UI から、任意の管理対象 AP でコントローラ機能を有効化できます。 ● 11ac Wave 2 AP のスタンドアロン モードで復元力を強化：11ac Wave 1 AP と 同様に、11ac Wave 2 AP でもスタンドアロン モードがサポートされます。マスター AP がオフラインになった場合でも、これらの AP に接続しているクライアントは接続し たままになり、ローカルでのデータ送受信が継続されます。 ● カスタマイズされたゲストポータル：CMX Connect によってカスタム ポータルとソー シャル ログインがサポートされます。 3 ステップ セットアップ ウィザード マスター AP ワイヤレス コントローラ

ル帯域幅の拡大に伴う電波干渉の可能性を最小化します。 ● ローミングの最適化：すべてのクライアントの接続品質を監視して、パフォーマンスが低 下しているクライアントには適切な接続を探すように早い段階から促すことで、ユーザ エクスペリエンスの低下を防止します。 ● 動的な帯域幅選択：レーダー信号を検出した場合に現在のチャネルすべてを変更する のではなく、チャネル帯域幅を自動的かつインテリジェントに構成して回避します。 ● ゼロインパクト AVC※1 ：専用のハードウェア アクセラレーションを使用することで、通 信速度に影響を与えずにアプリケーションを可視化および制御できます。 11ac 対応 Cisco CleanAir Cisco CleanAir は、自己回復および自己最適化する無線 LAN 環境を構築できる、集 中管理型ワイヤレス ソリューションの革新的なテクノロジーです。 電波干渉の原因を特定するために、従来のテクノロジーでは、ネットワーク管理者がセン サーを備えたノート PC を持って動き回る必要がありました。Cisco CleanAir では、ASIC （専用カスタム チップ）を搭載した Cisco Aironet アクセス ポイント自体が無線環境の計 測器やアナライザーとしての役割を兼ね備えているだけでなく、Cisco Aironet アクセス ポイントから得られた情報が可視化されて提供されるため、ネットワーク管理者はデスクに いながら原因を特定し、迅速かつ効率的に問題を解決できます。また、電波干渉検出後に 周波数帯を自動最適化して問題を緩和する、電波資源管理機能も提供します。 Cisco Aironet 1570/2700/3700 シリーズは、11ac Wave 1 の 80 MHz チャネル 帯域幅、Cisco Aironet 1560/2800/3800 シリーズは、11ac Wave 2 の 160 MHz チャネル帯域幅をサポートしています。 11ac 対応 Cisco ClientLink 低速なクライアント（たとえば 11a/g 対応クライアント）と高速なクライアント（たとえば 11n/ ac 対応クライアント）が混在する環境では、低速なクライアントによって無線 LAN 全体の 通信パフォーマンスが低下します。Cisco Aironet アクセス ポイントが実装する Cisco ClientLink は、チップセットに組み込まれた信号処理拡張機能によってクライアントか らのアップリンク通信の信号を解析、ダウンリンク通信の信号を強化および最適化し、低 速なクライアントの通信パフォーマンスを向上させるテクノロジーです。Cisco Aironet 1560/1570/2700/2800/3700/3800 シリーズが実装する Cisco ClientLink 3.0/4.0 では、アクセス ポイントの 3 本目または 4 本目のアンテナによって、iPhone や iPad、最 新のノート PC も含めて、対応データ ストリーム数が 3 ストリームまでの 11n/ac 対応クラ イアントの通信パフォーマンスも向上させます。 n a/g n n n 11a/b/g/n/ac デバイスが混在する環境で あらゆるデバイスのスループットおよびチャネル容量が向上 デバイス側での特別なテクノロジーの実装は不要 ac IEEE 802.11ac IEEE 802.11ac（11ac）は、現在の主流である無線規格 IEEE 802.11n（11n）の後継規 格です。理論値で最大 600 Mbps の 11n に対して、最大 6.9 Gbps という有線 LAN をも凌駕する通信速度を実現します。11ac は次の 3 点を強化することで、通信速度を高 めています。 ● より高密度の変調方式：64QAM から 256QAM（11n）に増加 ● チャネル ボンディングの拡張：最大 40 MHz（11n）から最大 80 MHz（11ac Wave 1） さらには最大 160 MHz（11ac Wave 2）に増加 ● より進化した MIMO（Multiple Input Multiple Output）：11n の最大 4 データ ストリー ムから最大 8 データ ストリームに増加、11n の 1 対 1 同時通信から 1 対 n 同時通 信に増加（マルチユーザ MIMO） シスコのワイヤレス アクセス

コミュニケーション （呼制御 / メッセージング） セキュリティ （ファイアウォール /IPS/VPN） WAN 最適化 Cisco ISR のラインアップ 従来は小規模な拠点でも、スイッチ、ワイヤレス アクセス ポイント、WAN 最適 化アプライアンスなどの、さまざまなデバイスの設置が必要でした。Cisco ISR （Integrated Services Router；サービス統合型ルータ）は、このような複数の デバイスから構成されるネットワーク サービスを 1 つのプラットフォームに統合できる 「スーパー ルータ」です。複数のサービスを統合するだけでなく、ライセンスの有効 化や拡張モジュールの追加によって、必要に応じて新しいサービスを追加することも可 能です。これらのルータを導入することで、ネットワークの構成がシンプルになり、デ バイスのコスト、および運用とメンテナンスに要するコストが削減されます。 42 ルータ Cisco ISR 4000 シリーズへ移行するメリット シスコの 20 年にわたるブランチ オフィス ルータの歴史を受け継ぐ Cisco ISR 4000 シリーズは、現代のブランチ オフィスのニーズに応える新たなサービスやパ フォーマンスを備え、ビジネスに次のようなメリットをもたらします。 ● 新たなリモート オフィスを迅速に開設、または付加サービスを簡単に追加可能 ● ブランチ オフィス全体を単一のプラットフォームで運用可能 ● 日常的な作業を自動化、およびセキュリティやアプリケーションのサービスを組織化するこ とで、IT 部門が開発に費やせる時間が増加 Cisco ISR 4000 シリーズによって、旧世代の Cisco ISR による現行サービスを廃 止することなく、現代のブランチ オフィスが直面する諸問題に対処できるようになりま す。ネットワークの仮想化機能によって、ビジネス ニーズの変化に応じて迅速にサー ビスを導入したり、リソースを再割り当てしたりすることもできます。また、ローカル アプリケーションのサバイバビリティ（生存可能性）、データ バックアップ、ローカル分 析処理に必要な処理能力をもたらします。 Cisco ISR 4000 シリーズの新たなアーキテクチャは、統合プラットフォームにおい て最大 2 Gbps の速度を誇ります。これは旧世代の Cisco ISR と比較すると、お よそ 4 ～ 10 倍の速度になります。Cisco ISR 4000 シリーズの WAN およびアプ リケーション最適化サービスには、Cisco Application Visibility and Control （AVC）および Cisco Performance Routing Version 3（PfR v3）が含まれ ます。前者は IT の容量プランニングのアセスメントを可能にし、後者は現状のネット ワーク条件において最良の接続でトラフィックを自動送信します。このアーキテクチャ によって、ブランチ オフィスのネットワークを単一のプラットフォームで運用できるだけ でなく、ネットワーク、コンピューティング、ストレージのリソースを同じプラットフォー ムに統合できるようになります。Cisco ISR 4000 シリーズの内部や、オプションの データ センタークラスのサーバ モジュール（Cisco UCS E シリーズ サーバ）経由で 使用できる仮想化テクノロジーが、新たなレベルの統合能力を提供します。 Cisco ISR の選択 トラフィックが集中するセンター側には、拠点側よりもパフォーマンスと拡張性が高い ルータを選択します。Cisco ISR では、センターや拠点で必要とされるサービスに応 じてバンドル モデルを選択できるだけでなく、ライセンスによる Cisco IOS テクノロ ジーの有効化や拡張モジュールの追加によって、ビジネス ニーズの変化にも柔軟に対 応できます。 Cisco ISR 4431 センター ■

........................................................................................................................................74 Cisco Validated Design page 1 Software-Defined Access introduction Software-Defined Access introduction Cisco® Software-Defined Access (SD-Access) is an application package that runs on the Cisco DNA Center™ controller for designing, provisioning, applying policy, and facilitating the creation of an intelligent campus wired and wireless network with assurance. Fabric technology for the campus, an integral part of SD-Access, introduces programmable overlays enabling easy-to-deploy network virtualization across the wired and wireless campus. In addition to network virtualization, fabric technology for campus provides software-defined segmentation and policy enforcement based on user identity and group membership. Software-defined segmentation is seamlessly integrated using Cisco TrustSec® technology, providing micro-segmentation through the use of scalable groups within a virtual network. Using DNA Center to automate the creation of virtual networks provides reduction in operational expenses, coupled with the advantage of reduced risk with integrated security and improved network performance provided by the assurance and analytics capabilities. This guide describes an implementation for deploying an SD-Access network using DNA Center, integrated into an existing enterprise network. The virtual networks that SD-Access builds (overlay networks) run on a physical network (underlay network), creating alternative topologies for connecting devices in the campus LAN. Similarly, overlay networks are commonly used to provide Layer 2 and Layer 3 logical networks with virtual machine mobility in data center fabrics (examples: Cisco ACI™, VXLAN, and Cisco FabricPath). Overlay networks are also used in wide-area networks to provide secure tunneling from remote sites (examples: MPLS, DMVPN, and GRE). This guide helps you understand important elements of automating SD-Access configurations and the integration into existing networks. As described in the Software-Defined Access Design Guide, the underlay network is defined by the physical switches and routers that are part of the campus fabric. All network elements of the underlay must establish IP connectivity via the use of a routing protocol, just as when building a traditional campus network. Instead of using arbitrary network topologies and protocols, this implementation uses a well-designed Layer 3 foundation inclusive of the campus edge switches (also known as a routed access design), ensuring performance, scalability, and high availability of the network. In the campus fabric, end-user subnets are not part of the underlay network, even though the underlay infrastructure equipment supports the end-user physical connectivity. You use the underlay as the supporting infrastructure when creating one or more overlay networks, which run across a set of the underlay network devices. The data plane traffic and control plane signaling is contained within each virtualized network, maintaining isolation among the networks in addition to isolation from the underlay network. The SD-Access fabric implements virtualization by encapsulating user traffic over IP packets that are sourced and terminated at the boundaries of the fabric, extending all the way to APs for wireless clients. Because IP-based connectivity within each Layer 3 overlay is an abstraction from the physical connectivity, multiple IP networks can be a part of each virtual network. In multi-tenant style deployments where you relinquish control of the addressing for each tenant’s Layer 3 overlay, you likely have to allow for some nonunique IP address space appearing in more than one overlay. You can support the overlapping IP address space requirement by preserving the traffic separation beyond the fabric border using typical virtualization techniques— including adding devices to remediate addressing conflicts (typically using network address translation) and provisioning to enable communication with permitted common external IP services such as DNS and the Internet. Cisco Validated Design page 2 Software-Defined Access introduction Figure 1. Layer 3 overlay—connectivity logically routed 7104F Physical Topology Physical Topology Logical Layer 3 Overlay Edge Nodes Border Nodes In addition to network virtualization, the campus fabric integrates Cisco TrustSec technology to enable softwaredefined segmentation and policy enforcement based on user identity and group membership. In this deployment, security policy management uses Cisco Identity Services Engine (ISE). Scalable group tags (SGTs), also known as security group tags, are integrated into the campus fabric headers. For group policies that extend outside of the campus, you configure the propagation of the SGT information from the fabric border node outside of the campus by either transporting the tags to TrustSec-aware devices using SGT exchange protocol (SXP) or by directly mapping SGTs to Cisco Meta Data using inline tagging capabilities implemented for connections to the border. Implementation overview Although there are certainly a wide variety of alternative deployment options to the topologies, protocols, and designs shown in this implementation, organizations are encouraged to start implementations with these configurations and then customize them to fit their needs. Within this guide, the deployment of the underlay network is a Layer 3 routed access topology using the Intermediate System to Intermediate System (IS-IS) routing protocol with fast network convergence properties available using equal-cost multipath (ECMP) routing. Underlay topologies for the fabric should not use the classic Layer 2 access design components, such as EtherChannel, in a fabric implementation for the SD-Access 1.1 solution. The overlay networks deployed are IP-only and connect with the rest of the enterprise network at the fabric border nodes as a function enabled on the campus core devices. Network virtualization extending outside of the fabric is preserved using VRF-lite, a virtualization technology commonly used to enable multiple separated Layer 3 routing and forwarding functions within a device. Cisco Validated Design page 3 Software-Defined Access introduction Outside of the fabric, you enable any required connectivity among virtual routing and forwarding instances (VRFs) and to services (typically residing within either the global routing table or a dedicated VRF) using classic virtualization techniques, which preserve the separation while allowing communication on an as-needed basis. When you consider integrating the campus fabric into an existing enterprise network, there are two key network design considerations, and each drives unique requirements for the integration: • Virtualized network: If the network is already virtualized, the VRFs at the campus fabric border extend into that virtualization technique of choice by using VRF-lite as a handoff into the existing virtualized infrastructure, whether it is MPLS, Multi-VRF, or some other technique. • Non-virtualized network: If the existing network is not virtualized, the recommended, validated interconnection between the fabric border and the non-virtualized network uses an intermediate device (fusion router) to enable route exchange between the domains and enabling shared services across all the virtual networks. Dual fusion routers are deployed for increased availability and use Border Gateway Protocol (BGP) as an exterior gateway protocol to the fabric border, which easily accommodates loop avoidance. In the deployment described, the campus core layer hosts the border functionality. An alternative border for smaller networks using a collapsed core/distribution using stackable switches is also described. Using the core as the border offers the overlay benefits across the entire campus LAN at the common campus exit point. The location where traffic exits the fabric as the default path is the external border. There are alternative choices for the external border, such as extending the border further into the enterprise, perhaps by extending the fabric all the way to the Internet edge. For trial deployments, the entire fabric could consist of a pair of distribution switches (or a collapsed core/distribution at a smaller site) performing the fabric external border role along with associated access switches at the fabric edge. When implementing this, recognize that the fabric benefits are limited to the devices covered by the extent of the border-to-edge fabric domains. If there is a requirement to have another location in the fabric as an alternative exit point for a specific set of non-default traffic (perhaps a WAN location, for example), additional border devices are used to support the requirement. The scope of border deployment guidance in this version of the deployment guide is for the more common external border configurations. Design considerations When deploying SD-Access, there are a number of significant deployment decisions to consider prior to starting, as described in the Software-Defined Access Design Guide. These considerations include: • Are you ready to deploy a Layer 3 (routed) access layer? This deployment assumes Layer 3 access for the network. Although any topology and routing protocol could be used in the underlay, the implementation of a well-designed Layer 3 foundation all the way to the campus edge is required to ensure support for performance, scalability, and high availability of the network. To achieve this goal for underlay deployments not manually created, the DNA Center LAN Automation feature deploys new networks using an IS-IS routed access design. Though there are many alternatives, the selection offers operational advantages such as neighbor establishment without IP protocol dependencies, peering capability using loopback addresses, and agnostic treatment of IPv4, IPv6, and non-IP traffic. • Subnet planning is an integral consideration if you are planning a migration from a Layer 2 to a routed access layer. All the same, SD-Access introduces the flexibility to remove traditional routed access layer restrictions associating client subnets to the closest Layer 3 gateway and allows subnets to stretch through the SDAccess fabric to support a specific function, such as connectivity for computers, unified communications, or wireless LAN access points. Cisco Validated Design page 4 Software-Defined Access introduction • Do you plan to deploy the underlay manually in a custom configuration as an extension to the routing protocol already used throughout an organization, or do you intend to use a dedicated interior gateway protocol (IGP) for the fabric underlay? This deployment shows a separate IGP using IS-IS for the underlay, which has a welldefined scope that is useful in automating new deployments. • Are there requirements to deploy multiple Layer 3 overlay networks (such as for multitenant use cases described in the Introduction), or does a single Layer 3 overlay with multiple stretched subnets meet the requirements? The deployment accommodates both types of deployments by supporting one or multiple VRFs extended outside the fabric domain. Nevertheless, consider that multiple overlays require additional planning for integration of common services into the multi-VRF environment. In both scenarios, you need to plan for and document all overlay subnets and VRFs for the host pools and be prepared to integrate them into your Dynamic Host Configuration Protocol (DHCP) services. • Have you identified the appropriate locations for the edge, border, and control plane roles in your network? Do you have the proper platforms in place to support those fabric roles? Full discussion of these platforms and roles is covered in the associated Software-Defined Access Design Guide. It is important to understand that, unlike in a trial deployment, a production deployment will present operational challenges if you deploy the border in one location and later decide to relocate it to another location, so careful consideration of the future fabric coverage scope is important. In the validated deployment described, the most common scenarios with supported platforms are shown, and Appendix A: Product List. lists the equipment specifically validated for roles in this deployment. Additional information If you didn’t get this guide from Cisco Design Zone, you can check for the latest version of this guide. You can find the Software-Defined Access Design Guide, User-to-Data Center Access Control Using TrustSec Deployment Guide, and related design guides, deployment guides, and white papers in the Design Zone at the following page: https://www.cisco.com/go/designzone Cisco Validated Design page 5 Deployment details Deployment details The enterprise network integrated with the described campus fabric deployment is nonvirtualized and runs Enhanced Interior Gateway Routing Protocol (EIGRP) as a routing protocol. IP prefixes from the campus, including shared services, must be available to both the fabric underlay and overlay networks while maintaining isolation among overlay networks. To maintain the isolation, VRF-Lite extends from the fabric border nodes to a set of fusion routers. The fusion routers implement VRF route leaking using a BGP route target import and export configuration and perform mutual redistribution with EIGRP in the enterprise network and with BGP to the campus fabric. A route-map configuration for dynamic tagging and filtering of redistributed routes provides a simple and dynamic way to prevent routing loops while accommodating multiple redistribution points in the high-availability design. Process Installing controllers for an SD-Access network 1. Install DNA Center The Cisco SD-Access 1.1 solution described in this guide uses a single DNA Center controller hardware appliance, prepared for inclusion as part of a cluster in the future. For this solution, DNA Center integrates with two ISE nodes configured for redundancy and dedicated to the SD-Access deployment, as detailed in the installation. To support SD-Access Wireless, the solution includes two wireless LAN controllers (WLCs) for controller redundancy. Before you begin, you must identify the following: • IP addressing and network connectivity for all controllers being deployed: DNA Center must have Internet access for system updates from the Cisco cloud repository. • A network-reachable Network Time Protocol (NTP) server, used during DNA Center installation to help ensure reliable digital certificate operation for securing connections. • Certificate server information, if you choose not to use self-signed digital certificates for a single node: For three-node cluster configurations, certificates generated by a certificate authority are required. Cisco Validated Design page 6 Deployment details Procedure 1 Install DNA Center The DNA Center appliance has 10-Gbps SFP+ modular LAN on motherboard (mLOM) interfaces and integrated copper interfaces available for network connectivity. Use the following table to assist with IP address assignment and connections. Validation is shown using a virtual IP (VIP) configured on a standalone DNA Center appliance, making it easier to migrate to a three-appliance cluster in the future. You do not need to physically connect the intra-cluster communications port for a standalone configuration. For provisioning and assurance communication efficiency, DNA Center should be installed in close network proximity to the greatest number of devices being managed. Figure 2.

For deployments requiring multiple interfaces separating administrative access and network infrastructure provisioning, static route changes after installation may require reconfiguration. If reconfiguration is required, follow the procedure to reconfigure the appliance using the wizard in the Cisco Digital Network Architecture Center Appliance Installation Guide. Cisco Validated Design page 7 Deployment details Reserve an arbitrary private IP space at least 20 bits of netmask in size that is not used elsewhere in the network. Divide the /20 address space into two /21 address spaces and use them in a later setup step for services communication among the processes running in a DNA Center instance. The address space is required for both a single-server configuration and a three-server configuration. The DNA Center appliance also must have Internet connectivity, either directly or via a web proxy, to obtain software updates from the Cisco cloud repository. Internet access requirements and optional proxy server setup requirements are detailed in the Cisco Digital Network Architecture Center Appliance Installation Guide. Step 1: Connect the DNA Center server to a Layer 2 access switch port in your network, by: • Using the 10Gb port labeled PORT 1 on the mLOM card (named enp9s0 in the wizard) • Using the Cisco Integrated Management Controller (IMC) port (labeled M on the embedded Ethernet ports) • Optionally using any other ports required for the installation, such as the dedicated web management port, an isolated enterprise network port, or cluster configuration port. The following example steps are described in detail with all options within the Installation Guide for the appliance software version. Use the guide to configure Cisco IMC on the appliance during first boot, along with the credentials required for Cisco IMC access. The Installation Guide describes the complete set of options, including joining a host to another host to create a cluster and configuring the left port (labeled PORT 2 on the mLOM card, and named enp10s0 in the wizard) for intra-cluster communications. The example that follows configures a standalone host or the first host in a cluster deployment, without a network proxy. Step 2: Boot the DNA Center hardware appliance. A welcome message appears. Welcome to the Maglev Configuration Wizard! Step 3: Press Enter to accept the default choice, Start a DNA-C Cluster.

Cisco Validated Design page 12 Deployment details Step 20: At the main DNA Center dashboard, click the settings (gear) icon, and then click About DNA Center. Step 21: Check that the version is at least 1.1.6. If your version is earlier than 1.1.6, contact support to reimage your DNA Center Appliance to version 1.1.6 or later before continuing. Version 1.1.6 is the minimum software requirement to upgrade to version 1.1.8, shown in a later step. Step 22: At the main DNA Center dashboard, click Add applications. The Application Management – Packages and Updates screen displays. This screen is used to install packages, adding functionality to the controller, including SD-Access. Cisco Validated Design page 13 Deployment details Tech tip For the validated version of DNA Center and SD-Access listed in Appendix A: Product List, a system update from the Internet is required. Check the release notes for your target software version for the appropriate procedures and dependencies. DNA Center release notes are found at: https://www.cisco.com/c/en/us/support/cloud-systems-management/dna-center/products-releasenotes-list.html The release notes include firewall access requirements for connecting DNA Center to the Internet to download packages from the cloud catalog server. DNA Center software newer than the version used for this validation may also support additional platform images, which can be found by searching Cisco.com for SD-Access Hardware and Software Compatibility Matrix. DNA Center automatically connects to the Cisco cloud repository to find the latest updates. You can use the Refresh button to reveal any updates that are found over time. Tech tip When deploying with this guide, do not use the DNA Center 1.2 Switch Now button, if it appears. This guide covers SD-Access using only DNA Center 1.1 versions of the software. Step 23: Click the settings (gear) icon, click System Settings, and then navigate to App Management > System Updates. The Application Management – System Updates screen is displayed. Step 24: Under the Available Update column, in the row showing System, if there is an available update, click Install. A download of the new system update begins, which can take many minutes. Then the installation starts automatically, which can take more than an hour. Use the Refresh button to check the status until the updated Installed Version is displayed with a Running status. The System package within the System Updates section is the only package you download or update during the initial system update. After the installation of the system is complete, you then download and install the application package updates. Cisco Validated Design page 14 Deployment details Tech tip Illustrations are installation examples. Software versions used for validation are listed in Appendix A: Product List.

At the top of the list, select all packages by selecting the box next to Package, click the Actions pull-down menu, and then select Download. Step 26: At the popup, select OK to confirm the download operation. The screen updates, showing all of the packages that are being downloaded. Before proceeding to the next step, refresh the screen until there are no longer any packages showing a status of Downloading. The download can take many minutes to complete. Step 27: After the new versions of the packages are downloaded, install the packages, including the latest version of the SD-Access package. Select all packages in common that have a new Downloaded Version available, at the top of the window click the Actions pull-down menu, select Update, and then click OK. The package updates begin. Use the browser refresh button to see the updated status for each package. The update process can take over an hour to complete. Tech tip Packages must be updated in a specific order to appropriately address package interdependencies and should be updated only after the system updates have completed. Allow DNA Center to handle dependencies by selecting and updating all package updates at once; otherwise refer to the Installation Guide for the correct package update sequence. The Installation Guide also explains how to use the Maglev CLI to force a download retry for any stalled download. Cisco Validated Design page 15 Deployment details The Actions menu is unavailable until package tasks are complete. Wait until packages no longer show a Status of Pending Update, Preparing Update, or Updating before proceeding. While the packages are installing, which takes some time, you may work in parallel on the next process for installing the Identity Services Engine nodes. After the Automation – SD Access package is in Running status, along with any other updated packages, the functionality is available to use, and integration with the installed ISE nodes can proceed. Step 28: Validate that the correct versions of DNA Center and all packages are now installed. At the main DNA Center dashboard, click the settings (gear) icon, click About DNA Center, and then click Show Packages. Process Install Identity Services Engine nodes 1. Install ISE server images 2. Configure roles for ISE nodes 3. Register ISE node 2 and configure roles The SD-Access 1.1 solution described in this guide uses two ISE nodes in a high-availability standalone configuration dedicated to the SD-Access network and integrated into DNA Center management. The first ISE node has the primary Policy Administration Node (PAN) persona configuration and the secondary monitoring and troubleshooting (MnT) persona configuration. The second ISE node has the secondary PAN persona configuration and the primary MnT persona configuration. Both nodes include Policy Services Node (PSN) persona configurations. You also enable pxGrid and External RESTful Services (ERS) on the ISE nodes. Cisco Validated Design page 16 Deployment details Table 2.

Cisco Validated Design page 21 Deployment details Process Integrate Identity Services Engines with DNA Center 1. Configure DNA Center authentication and policy servers Integrate ISE with DNA Center by defining ISE as an authentication and policy server to DNA Center and permitting pxGrid connectivity from DNA Center into ISE. Integration enables information sharing between the two platforms, including device information and group information, and allows DNA Center to define policies to be rendered into the network infrastructure by ISE. Tech tip Validation shows DNA Center integrated with ISE servers. Although it is possible to avoid the integration of ISE, policy configuration such as using scalable group tags and group-based policies will not be possible and there will be a loss of automation, resulting in the requirement to manually assign edge ports to VNs, which is not a part of the validation shown. Procedure 1 Configure DNA Center authentication and policy servers Step 1: Log in to the DNA Center web interface, at the top-right corner select the gear icon, and then navigate to System Settings. Cisco Validated Design page 22 Deployment details Step 2: Navigate to Settings > Authentication and Policy Servers, and then click on the + Add button. Tech tip The next step for integrating an ISE installation is the same whether you use a high-availability standalone ISE deployment, as validated, or a distributed ISE deployment. The shared secret chosen needs to be consistent with the shared secret used across the devices in the network for communicating with the authentication, authorization, and accounting (AAA) server. The username and password are used for DNA Center to communicate with ISE using SSH, and must be the default super admin account that was created during the ISE installation. Step 3: In the Add AAA/ISE SERVER display, enter the ISE node 1 (primary PAN) Server IP Address (example: 10.4.49.30) and Shared Secret, toggle the Cisco ISE selector, enter the ISE Username (example: admin), enter the ISE Password, enter the ISE fully-qualified domain name for FQDN (verified with a DNS lookup at submission— cut-and-paste from a browsing session to ISE aids with entry accuracy), enter Subscriber Name (example: dnac), leave the SSH Key blank, and then click Apply. During communication establishment, status from DNA Center displays IN PROGRESS. Use the Refresh button until communication establishes with ISE and the server displays ACTIVE status. If communication is not established, an error message displays with information reported from ISE regarding the problem to be addressed before continuing. You can also see the communication status by navigating from the gear icon to System Settings > System 360. Under External Network Services, the Cisco ISE server shows in Available status. With communications established, DNA Center requests a pxGrid session with ISE. Step 4: Log in to ISE, and then navigate to Administration > pxGrid Services. The client named dnac is now showing Pending in the Status column. Cisco Validated Design page 23 Deployment details Step 5: Check the box next to dnac, above the list click Approve, and then click Yes to confirm. A success message displays, and the Pending status changes to Online (XMPP). You can additionally verify that the integration is active by expanding the view for the client and observing two subscribers, Core and TrustSecMetaData. If ISE is integrated with DNA Center after scalable groups are already created in ISE, in addition to the default groups available, any existing ISE groups are also visible by logging in to DNA Center and navigating to Policy > Registry > Scalable Groups. Existing ISE policies are not migrated to DNA Center. Process Install SD-Access wireless LAN controllers 1. Configure the WLC Cisco AireOS platforms using the startup wizard For this deployment, dedicate the WLCs to SD-Access Wireless connectivity by integrating them natively with the fabric. The WLCs use link aggregation to connect to a redundant Layer 2 shared services distribution outside of the SD-Access fabric, as described in the Campus LAN and Wireless LAN Design Guide. Use this guide to configure a pair of Cisco WLCs with high availability stateful switchover (HA SSO) resiliency, and all of the network connectivity should be in place before starting the configuration procedure. Because each fabric border node is an independent routed device, redundant WLCs should not be connected at the border, but rather to a set of devices configured to support the Layer 2 redundancy suitable for the HA SSO WLCs, such as a switch stack, Cisco Virtual Switching System, or Cisco StackWise® Virtual. Tech tip The SD-Access 1.1 solution supports transport of only IP frames in the Layer 2 overlays that are used for WLAN, without Layer 2 flooding of broadcast and unknown multicast traffic. Without broadcasts from the fabric edge, Address Resolution Protocol (ARP) functions by using the fabric control plane for MAC-to-IP address table lookups. For transport of non-IP frames and Layer 2 flooding, see the release notes for your software version in order to verify updated support. Cisco Validated Design page 24 Deployment details Tech tip To add WLAN as part of SD-Access 1.1 with the software releases listed in Appendix A: Product List, while using Cisco Catalyst® 6800 Series fabric border devices not supporting the wireless control plane, you must use separate control plane devices that do include wireless support. See the release notes for any changes to WLAN Layer 2 control plane support when using the Cisco Catalyst 6800 Series. Procedure 1 Configure the WLC Cisco AireOS platforms using the startup wizard Perform the initial configuration using the CLI startup wizard. After powering up the WLC, you should see the following on the WLC console. If not, type - (dash) followed by Enter repeatedly until the startup wizard displays the first question. Welcome to the Cisco Wizard Configuration Tool Use the ‘-‘ character to backup Step 1: Terminate the auto-install process. Would you like to terminate autoinstall?

Enable Link Aggregation (LAG) [yes][NO]: YES Cisco Validated Design page 25 Deployment details Step 6: Enter the management interface IP address, mask, and default router. The IP address for the secondary controller of an HA SSO pair is used only temporarily until the secondary WLC downloads the configuration from the primary and becomes a member of the HA controller pair. Management Interface IP Address: 10.4.174.26 Management Interface Netmask: 255.255.255.0 Management interface Default Router: 10.4.174.1 Step 7: Configure the Management Interface VLAN Identifier. Management Interface VLAN Identifier (0 = untagged): 174 Step 8: Configure the Management Interface Port Number. The displayed range varies by WLC model. This number is arbitrary after enabling LAG, because all management ports are automatically configured and participate as one LAG, and any functional physical port in the group can pass management traffic. Management Interface Port Num [1 to 2]: 1 Step 9: Enter the DHCP server for clients. (Example: 10.4.48.10) Management Interface DHCP Server IP Address: 10.4.48.10 Step 10: Do not enable HA SSO. DNA Center automates the HA SSO controller configuration during device provisioning. Enable HA (Dedicated Redundancy Port is used by Default)[yes][NO]: NO Step 11: The WLC uses the virtual interface for mobility DHCP relay, guest web authentication, and intercontroller communication. Enter an IP address that is not used in your organization’s network. Virtual Gateway IP Address: 192.0.2.1 Step 12: Enter a multicast address that will be used by each AP to subscribe to IP multicast flows coming from the WLC. This address will be used only when configuring the IP multicast delivery method called multicast-multicast. Multicast IP Address: 239.1.1.1 Tech tip The multicast address must be unique for each controller or HA pair in the network. The multicast address entered is used as the source multicast address, which the access points registered to the controller use for receiving wireless user-based multicast streams. Step 13: Enter a name for the default mobility and RF group. Mobility/RF Group Name: SDA-Campus Step 14: Enter an SSID for the data WLAN. This is used later in the deployment process. Network Name (SSID): SDA-Data Step 15: Disable DHCP Bridging Mode. Configure DHCP Bridging Mode [yes][NO]: NO Cisco Validated Design page 26 Deployment details Step 16: Enable DHCP snooping. Allow Static IP Addresses [YES][no]: NO Step 17: Do not configure the RADIUS server now. You will configure the RADIUS server later using the GUI. Configure a RADIUS Server now? [YES][no]: NO Warning! The default WLAN security policy requires a RADIUS server. Please see documentation for more details. Step 18: Enter the country code where you are deploying the WLC. Enter Country Code list (enter ‘help’ for a list of countries) [US]: US Step 19: Enable all of the required wireless networks. Enable 802.11b network [YES][no]: YES Enable 802.11a network [YES][no]: YES Enable 802.11g network [YES][no]: YES Step 20: Enable the radio resource management (RRM) auto-RF feature. Enable Auto-RF [YES][no]: YES Step 21: Synchronize the WLC clock to your organization’s NTP server. Configure a NTP server now? [YES][no]:YES Enter the NTP server’s IP address: 10.4.0.1 Enter a polling interval between 3600 and 604800 secs: 86400 Step 22: Do not configure IPv6. Would you like to configure IPv6 parameters[YES][no]:NO Step 23: Confirm that the configuration is correct. The WLC saves the configuration and resets automatically. Configuration correct? If yes, system will save it and reset. [yes][NO]: YES … Configuration saved! Resetting system with new configuration… If you press Enter or respond with no, the system resets without saving the configuration, and you will have to complete this procedure again. The WLC resets and displays a User: login prompt. (Cisco Controller) Enter User Name (or ‘Recover-Config’ this one-time only to reset configuration to factory defaults) User: Cisco Validated Design page 27 Deployment details Step 24: Repeat step 1 through step 23 for the secondary WLC, using the appropriate parameters for it. Step 25: Use a web browser to verify connectivity by logging in to each of the Cisco WLC administration web pages using the credentials created in step 3 of Procedure 1. (Example: https://10.4.174.26) Step 26: Navigate to Commands > Set Time. Verify that the date and time agree with the NTP server. If the time appears to be significantly different, manually correct it, and also choose a time zone, if you commonly use something other than the default in the network infrastructure. The correct date and time are important for certificate validation and successful AP registration with the WLC. The controllers are ready for discovery and integration into the DNA Center setup. Additional controller reachability requirements, such as a specific route at the edge nodes to the WLC, are addressed in later integration procedures. Deploying SD-Access Process Using DNA Center for initial network design and discovery 1. Create network sites 2. Configure network services for sites 3. Add device credentials for discovery and management 4. Reserve IP address pools for network provisioning Using DNA Center, you create a network hierarchy of sites that can contain additional sites or buildings and floors within sites. Devices map into buildings for configuration. Cisco Validated Design page 28 Deployment details Procedure 1 Create network sites Step 1: Log in to DNA Center. Navigate to the main DNA Center dashboard, under the Design category, select Add site locations on the network. Step 2: Click Add Site to start a network design using the tool, supply an appropriate Site Name, and then click Add. Step 3: Click Add Site, select the Building button, supply an appropriate Building Name, select the site previously created as the Parent, complete the wizard to assign a location, and then click Add. To add a building, you can use an approximate street address near the building within the wizard and, if desired, refine the building position on the map by clicking the target location. Step 4: Repeat the previous steps as required to add sites and buildings, creating a hierarchy that makes sense for your organization. Cisco Validated Design page 29 Deployment details Step 5: If you are integrating wireless to a building, or want more granularity for network choices within a building, select the building on the map (or select the gear icon next to a building in the hierarchy), choose Add Floor, and complete the wizard with the details. Floors are referenced during the wireless provisioning. If you have floor map diagrams in DXF, DWG, JPG, GIF, or PNG formats, add them to any defined floors as a useful component for wireless deployments to show access point locations and coverage. You can add hundreds of sites up to the limits listed in the Software-Defined Access Design Guide. Procedure 2 Configure network services for sites Configure AAA, DHCP, and DNS services as required for the sites in DNA Center. If the services use the same servers across all of your sites, you can configure them globally, and the inheritance properties of the hierarchy make the global settings available to all sites. Differences for individual sites can then be applied on a site-by-site basis. This procedure shows the configuration globally. Cisco Validated Design page 30 Deployment details Step 1: Within DNA Center, navigate to DESIGN > Network Settings > Network. Within the left pane in the site hierarchy, select the appropriate level (example: Global), fill in the DHCP Server IP address (example: 10.4.49.10), under DNS Server fill in the Domain Name (example: ciscodna.net) and server Primary IP Address (example: 10.4.49.10), add any redundant or additional servers, and then click Save. Step 2: Near the top, next to Network Telemetry, click the + Add Servers button, select the AAA check box, and then click OK. The configuration pane is updated with AAA Server as an available configuration section, ready for configuring AAA services for both the network infrastructure device management and the client endpoints connecting to the infrastructure. For validation, the high-availability standalone ISE nodes are used with RADIUS for both the network infrastructure and the client endpoint authentication. Cisco Validated Design page 31 Deployment details Step 3: Select the Network checkbox, and select both the ISE and RADIUS radio buttons. Under Network, use the pull-down to select the prepopulated ISE server. Use the second pull-down that appears to select the IP Address (Primary) of the ISE server, select the plus sign (+) button, and then in the IP Address (Additional) pull-down select the redundant ISE server node. Step 4: Select the Client/Endpoint checkbox, and select both the ISE and RADIUS radio buttons. Under Client/Endpoint, use the pull-down to select the prepopulated ISE server. Use the second pulldown that appears to select the IP Address (Primary) of the ISE server, and then click Save. The ISE servers for AAA, the DHCP Server, and the DNS Server for the selected level in the site hierarchy are all saved to be used during fabric provisioning. Procedure 3 Add device credentials for discovery and management When you deploy the SD-Access underlay using devices that are already configured and which are network reachable by DNA Center, you discover and manage the devices by supplying the CLI and Simple Network Management Protocol (SNMP) credentials. As an option, you can deploy LAN switches without existing configurations into the underlay by using the DNA Center LAN Automation capabilities. Cisco Network Plug and Play (PnP) is the mechanism enabling connectivity and initial configuration for supported switches. For LAN Automation deployments, you also supply CLI and SNMP credentials to access and prepare one or more supported PnP seed devices, such as Cisco Catalyst 9500 Series Switches in a distribution or core. LAN Automation discovers switches directly connected to chosen seed device interfaces and up to one additional hop of connected switches, all of which must be running the PnP agent and have no previous configuration. The credentials supplied allow DNA Center and seed devices to work together to configure the discovered devices and add them into managed inventory. Add device credentials to manage scopes of the site hierarchy created in the design. These credentials enable discovery and management for the network. Cisco Validated Design page 32 Deployment details Step 1: Navigate to Design > Network Settings > Device Credentials, select an appropriate level of the site hierarchy in the left pane (example: Global for common credentials across the hierarchy), and acknowledge any pop-up alerts. Step 2: At the top of the CLI Credentials section, click Add, complete the Name / Description (example: IOS Devices), Username, Password, and Enable Password fields, and click OK. Caution If you are using ISE as your AAA server, you should avoid using admin as the username for device CLI credentials, which can lead to username conflicts with the ISE administrator login, resulting in the inability to log in to devices. Cisco Validated Design page 33 Deployment details Step 3: At the top of the SNMP Credentials section, select an SNMP credential type to update (example: SNMPv2c Read). Click Add, select the radio button in the row next to the credential to update (a single credential per row at a time), fill out the credential details, and click Save. Step 4: Repeat steps 2 and 3 for any additional credentials required in the hierarchy. CLI Credentials and both SNMPV2C Read and SNMPV2C Write are the most common requirements. Step 5: For each of the CLI and SNMP credentials assigned, click all radio buttons next to each assignment created, including ones where you toggle among the options (example: SNMPV2C Write). After each selection, at the bottom of the Device Credentials screen, click Save. A Created Common Settings Successfully acknowledgment is displayed. The device credentials to be used for network discovery and management are now available in DNA Center. Procedure 4 Reserve IP address pools for network provisioning Reserve IP addresses for your networks by manually assigning them in DNA Center. The assignments can be pushed to an IP address manager (IPAM) (examples: Infoblox, Bluecat) by integrating the IPAMs through APIs. You optionally integrate with an IPAM by navigating to the System Settings > Settings > IP Address Manager and filling out the form with the specifics of your IPAM provider. This procedure shows how to manually define the IP address pools that will be used later and then assign pools to be used by the sites in your network, which you do for both manual and IPAM configurations. You have the flexibility to create a larger global pool and then later reserve a subset of a pool at lower levels, such as for a specific site in the site hierarchy. When using the validated version of DNA Center listed in Appendix A: Product List, you use the global level only to create IP address pools. DHCP scopes configured on the DHCP server should support the address allocations and any additional DHCP options required to make a device work. For example, some IP telephony vendors require specific DHCP options to be configured to enable their devices to function correctly, which can be checked in product documentation. The global address pools in the table are added as part of the validation. Cisco Validated Design page 34 Deployment details Table 3. Global address pools used during validation Pool name Network/mask IP gateway DHCP server DNS server Border-Handoff 172.16.172.0/24 172.16.172.1 — — Access-Point 172.16.173.0/24 172.16.173.1 10.4.49.10 10.4.49.10 14-Underlay 10.4.14.0/24 10.4.14.1 10.4.49.10 10.4.49.10 14-Employee 10.101.114.0/24 10.101.114.1 10.4.49.10 10.4.49.10 14-Phone 10.101.214.0/24 10.101.214.1 10.4.49.10 10.4.49.10 14-Things 10.102.114.0/24 10.102.114.1 10.4.49.10 10.4.49.10 14-Guest 10.103.114.0/24 10.103.114.1 10.4.49.10 10.4.49.10 LAN-Automation 10.5.100.0/24 10.5.100.1 10.4.49.10 10.4.49.10 Step 1: Add a global pool in DNA Center that is dedicated to fabric border node connectivity provisioning. Navigate to DESIGN > Network Settings > IP Address Pools. In the site hierarchy on the left, select Global, and click + Add IP Pool. Fill in the IP Pool Name, IP Subnet, CIDR Prefix, and Gateway IP address. If the pool has endpoint clients, assign DHCP Server(s) and DNS Server(s). Do not select Overlapping. When you are done, click Save. Repeat this step for any additional global IP pools that include subnets at the site and building levels. The pools are added to the list of global pools. Cisco Validated Design page 35 Deployment details Process Creating segmentation and policy for the SD-Access network 1. Add an overlay VN to the SD-Access network 2. Create a micro-segmentation policy using SGTs As part of the design decisions in advance of your SD-Access network deployment, you decide network segmentation strategies for the organization. Macro segmentation uses additional overlay networks in the fabric (VNs), and micro segmentation uses scalable group tags to apply policy to groups of users or device profiles. The desired outcomes of policy application using segmentation may be easily accommodated with group policies. In a university example, students and faculty machines may both be permitted to access printing resources, but student machines should not communicate directly with faculty machines, and printing devices should not communicate with other printing devices. In other cases, a higher degree of isolation is required. In a retail store example, the point-of-sale machines should never be in communication with the video surveillance network infrastructure, which in turn should never communicate with the building HVAC system. In cases where the isolation need extends from the edge of the network all the way to the core of the network for access to access centralized services, macro segmentation using VNs is the best choice. Governmental and industrial compliance requirements and an organization’s risk policies often drive the choice to use VNs. Use these procedures as examples for deploying your macro and micro segmentation policies. Cisco Validated Design page 36 Deployment details Procedure 1 Add an overlay VN to the SD-Access network Step 2: From the main DNA Center dashboard, navigate to POLICY > Virtual Network, click the + (plus sign) to create a new virtual network, enter a Virtual Network Name (example: Workers), drag scalable groups from the Available Scalable Groups pool into the Groups in the Virtual Network pool (examples: Employees and Developers), and then click Save. The VN with associated groups is defined and appears in the list of defined virtual networks. These virtual network definitions are available for provisioning fabrics. Tech tip If you don’t see any groups, likely the pxGrid connectivity between DNA Center and ISE is not fully operational. In this case, review the integration procedures for ISE with DNA Center and be sure to approve the pxGrid connection request in ISE from DNA Center. Repeat this step for each overlay network, either guest or non-guest, as required. You can also return to this step after the fabric is provisioned to create more overlay networks. Procedure 2 Create a micro-segmentation policy using SGTs Micro-segmentation policies are customized for an organization’s deployment. This simple example shows a basic policy that can be used to deny users within a VN from communicating with other employee devices and also from one another when a group called Quarantined_System is applied. Cisco Validated Design page 37 Deployment details Step 3: From the main DNA Center dashboard, navigate to POLICY > Policy Administration > Group-Based Access Control (Fabric), click + Add Policy, from the Available Scalable Groups pane drag the Quarantined_ System group and drop it into both the Source and the Destination panes, drag the Employees group into the Destination pane, input a Policy Name (example: Quarantine), enter a Description, select Enable Policy, leave Enable Bi-directional unselected, click + Add Contract, select deny, click OK, and then click Save. The policy is created and listed with a status of DEPLOYED. This policy is now available to be applied to fabrics that are created and is available in ISE. Step 4: Log in to ISE, navigate to Work Centers > TrustSec > TrustSec Policy, on the left side select Matrix, and verify that the policy has been updated to ISE for rendering into the network. Cisco Validated Design page 38 Deployment details Process Preparing the network for automation 1. Configure underlay network device management using the CLI 2. Configure underlay network links for routed access connectivity 3. Enable routing connectivity at border toward external router neighbor 4. Redistribute shared services subnets into underlay IGP 5. Enable connectivity at external fusion router towards border neighbor 6. Configure MTU on unmanaged intermediate devices 7. Discover and manage network devices 8. Configure underlay switches using LAN Automation 9. Manage software images for devices in inventory 10.Use software image management to update device software To be able to deploy the network designs and policies created, a functioning network underlay must exist with working management connectivity. Procedure 1 Configure underlay network device management using the CLI For maximum resiliency and bandwidth, use a loopback interface on each device and enable Layer 3 connectivity for DNA Center in-band discovery and management. The following steps configure point-to-point Ethernet connectivity between devices using IS-IS as the routing protocol and SSHv2 with SNMPv2c for device configuration to the device loopback interfaces. Do not add a configuration to any devices that you intend to discover and configure using LAN Automation as part of a later procedure. Devices with existing configurations cannot be configured using PnP onboarding. Step 1: Use the device CLI to configure the hostname to make it easy to identify the device. hostname [hostname] Step 2: Configure local login and password. username dna privilege 15 secret [user password] enable secret [enable password] service password-encryption Step 3: Configure Secure Shell (SSH) as the method for CLI management access. ip ssh version 2 line vty 0 15 login local transport input ssh transport preferred none Cisco Validated Design page 39 Deployment details Step 4: Enable Simple Network Management Protocol (SNMP) and configure SNMPv2c with both a read-only and a read-write community string, which match the credentials input into DNA Center. snmp-server community [SNMP read-only name] ro snmp-server community [SNMP read-write name] rw Step 5: Configure the switch to support Ethernet jumbo frames. The MTU chosen allows for the extra fabric headers and compatibility with the highest common value across most switches, and the round number should be easy to remember when configuring and troubleshooting. system mtu 9100 Step 6: Configure the switch loopback address. interface Loopback0 ip address [Device loopback IP address] 255.255.255.255 Procedure 2 Configure underlay network links for routed access connectivity Optional If your underlay network is already configured as a routed access network, skip this procedure. Do not add a configuration to any devices that you intend to discover and configure using LAN Automation as part of a later procedure. Devices with existing configurations cannot be configured using PnP onboarding. Step 1: Configure the switch connections within the underlay network infrastructure. Repeat this step for every link to a neighbor switch within the fabric underlay. If the device will be provisioned as a fabric border node and the connection is to be used as a handoff from the fabric to the rest of the infrastructure, use the next procedure instead. interface TenGigabitEthernet1/0/1 no switchport ip address [Point-to-point IP address] 255.255.255.254 Step 2: Enable IP routing and enable the IS-IS routing protocol on the switch. ! ip routing is not enabled by default for many switches ip routing router isis net 49.0001.0100.0400.0001.00 metric-style wide nsf ietf ispf level-1-2 passive-interface loopback0 log-adjacency-changes Cisco Validated Design page 40 Deployment details Tech tip A common convention in IS-IS is to embed the loopback IP address into the unique NET, or system ID. For example, a loopback IP address 10.4.32.1 (010.004.032.001) becomes 0100.0403.2001, and it is appended with .00 and prepended with the area ID (49.0001), resulting in NET 49.0001.0100.0403.2001.00. Step 3: Enable IS-IS routing on all of the configured infrastructure interfaces in the underlay, except for the border handoff interfaces, which are configured in the next procedure. The loopback interface is enabled to share the management IP address and the physical interfaces are enabled to share routing information with the connected infrastructure. interface Loopback0 ip router isis interface range TenGigabitEthernet1/0/1-2 , TenGigabitEthernet2/0/1-2 ip router isis Procedure 3 Enable routing connectivity at border toward external router neighbor If your underlay network is already configured as a routed access network and integrated with the rest of your network using BGP, skip this procedure. To connect border node devices into your network, you establish connectivity across interfaces configured using VRF-lite, which uses 802.1Q VLAN tagging to separate the VRFs. Connect common network services available outside of the border nodes such as DNS, DHCP, and WLCs, and for DNA Center management when it is not directly connected to the SD-Access network nodes, by extending your existing enterprise network to the underlay at the border. Connectivity to DNA Center is required for additional provisioning. The external device handling routing among multiple virtual networks and a global routing instance acts as a fusion router for those networks, and the separation of connectivity is maintained by using VRFs connected using interfaces with 802.1Q tagging to the border, also known as VRF-lite. Establishing the underlay connectivity using BGP allows DNA Center to manage initial discovery and configuration using the link, and then to use the same link augmented with additional tags and BGP sessions as needed for overlay VN connectivity. Step 1: For each border node, if you are configuring a switch supporting VLAN trunk interfaces such as Catalyst 9000, 3800, or 6800 Series switches, you must configure a trunk on the connected interface with a dedicated VLAN to establish underlay connectivity for route peering to the fusion router. vlan 100 interface vlan100 ip address [IP address] [netmask] no shutdown interface FortyGigabitEthernet1/0/24 switchport switchport mode trunk switchport trunk allowed vlan add 100 no shutdown Cisco Validated Design page 41 Deployment details Step 2: For each border node, if you are configuring a device such as an ASR or ISR router that supports 802.1Q VLAN tagging, use an alternative subinterface configuration instead of a switch trunk interface to establish underlay connectivity to the fusion router. interface TenGigabitEthernet0/1/0 no shutdown ! interface TenGigabitEthernet0/1/0.100 encapsulation dot1Q 100 ip address [IP address] [netmask] no shutdown Step 3: If you skipped the procedure to interconnect the underlay devices, connect the redundant border nodes together with at least one routed interface for underlay communication and later BGP peering. The configuration for integrating into the IS-IS protocol is shown. Repeat this step for each interface connecting border nodes. interface FortyGigabitEthernet1/0/23 no switchport ip address [Point-to-point IP address] 255.255.255.254 ip router isis no shutdown Step 4: Enable BGP routing to the fusion router in order to connect networks external to the fabric, and activate BGP for the connecting interfaces. You use BGP to allow DNA Center management access to the underlay network devices, while allowing further provisioning for virtual networks on the interfaces and minimizing disruption to network connectivity. Repeat this step for each border node. router bgp [underlay AS number] bgp router-id [loopback 0 IP address] bgp log-neighbor-changes ! fusion router is an eBGP neighbor neighbor [fusion interface IP address] remote-as [external AS number] ! redundant border is an iBGP neighbor neighbor [redundant border Lo0 address] remote-as [underlay AS number] neighbor [redundant border Lo0 address] update-source Loopback0 ! address-family ipv4 network [Lo0 IP address] mask 255.255.255.255 ! advertise underlay IP network summary in global routing table aggregate-address [underlay IP network summary] [netmask] summary-only redistribute isis level-2 neighbor [fusion interface IP address] activate neighbor [redundant border Lo0 address] activate maximum-paths 2 exit-address-family Cisco Validated Design page 42 Deployment details Procedure 4 Redistribute shared services subnets into underlay IGP A default route in the underlay cannot be used by the APs to reach the WLC. A more specific route (such as a /24 subnet or /32 host route) to the WLC IP addresses must exist in the global routing table at each node where the APs connect to establish connectivity. Permit the more specific routes for the WLC and DHCP shared services needed from BGP (examples: 10.4.174.0/24 and 10.4.48.0/21) into the underlay network by redistributing the shared services route at the border into the underlay IGP routing process using this procedure. Using this process, the prefixes used match prefixes in the BGP routing table. Step 1: Connect to the each border node and add a prefix-list and route-map for subnets used for the shared services. ip prefix-list SHARED_SERVICES_NETS seq 5 permit 10.4.48.0/21 ip prefix-list SHARED_SERVICES_NETS seq 10 permit 10.4.174.0/24 route-map GLOBAL_SHARED_SERVICES_NETS permit 10 match ip address prefix-list SHARED_SERVICES_NETS Step 2: At each border node, redistribute the prefixes into your underlay routing protocol. This example assumes ISIS. router isis redistribute bgp [underlay AS number] route-map GLOBAL_SHARED_SERVICES_NETS metric-type external Procedure 5 Enable connectivity at external fusion router towards border neighbor The fusion routers connected to your SD-Access fabric border routers require CLI configuration for BGP connectivity consistent with the border routers configured in the previous procedure. Follow this procedure at each external fusion router device that is connected to your border. Step 1: On each external fusion router, create the VRF, route distinguisher, and route targets for the initial management connectivity to the border. vrf definition VRF-GLOBAL rd 100:100 ! address-family ipv4 route-target export 100:100 route-target import 100:100 exit-address-family Cisco Validated Design page 43 Deployment details Step 2: For each connection from the external fusion router to the SD-Access fabric border, enable the interface, VLAN-tagged subinterface, and IP addressing. This example uses 802.1Q VLAN tagging on a router with subinterfaces. For switches requiring trunk port configurations, match the other side that was previously configured. interface TenGigabitEthernet0/1/7 description to Border mtu 9100 no ip address interface TenGigabitEthernet0/1/7.100 encapsulation dot1Q 100 vrf forwarding VRF-GLOBAL ip address [IP network] [netmask] IP connectivity is now enabled for the VLAN (example: 100) on the 802.1Q tagged connection between the fusion router and the border node. Step 3: Create route maps to tag routes and avoid routing loops when redistributing between the IGP used within the rest of the network and BGP when connecting using multiple links. IGPs can vary—the example shown is for EIGRP, completing the routing connectivity from IS-IS to BGP to EIGRP. route-map RM-BGP-TO-EIGRP permit 10 set tag 100 ! route-map RM-EIGRP-TO-BGP deny 10 match tag 100 route-map RM-EIGRP-TO-BGP permit 20 Step 4: Enable BGP peering from redundant fusion routers to the border nodes and redistribute the IGP that is used to reach the networks beyond the fusion routers. router bgp [external AS number] bgp router-id [loopback IP address] bgp log-neighbor-changes ! address-family ipv4 vrf VRF-GLOBAL redistribute eigrp 100 route-map RM-EIGRP-TO-BGP neighbor [redundant fusion IP] remote-as [external AS number] neighbor [redundant fusion IP] activate Cisco Validated Design page 44 Deployment details neighbor [border IP address] remote-as [underlay AS number] neighbor [border IP address] activate maximum-paths 2 default-information originate exit-address-family Step 5: Redistribute BGP into the IGP to enable reachability.

DNA Center already manages fabric edge nodes and border nodes; however, if you have intermediate devices within the fabric that will not be managed by DNA Center (example: hardware or software support isn’t available in DNA Center), then the devices must still meet the requirements for transporting SD-Access traffic through those transit fabric intermediate nodes. The primary requirements are that they: • Are Layer 3 devices that must be actively participating in routing within the other fabric underlay domain devices. • Must be able to transport the jumbo frames that are offered by the fabric encapsulation techniques. For unmanaged fabric intermediate node devices, you must set an appropriate MTU (example: 9100) and manually configure routing with the other devices in the underlay. Configuration guidance for this situation is device-specific and not discussed further in this guide. Do not add a configuration to any devices that you intend to discover and configure using LAN Automation as part of a later procedure. Devices with existing configurations cannot be configured using PnP onboarding. Cisco Validated Design page 45 Deployment details Procedure 7 Discover and manage network devices You discover and manage devices in a network to be used as the underlay for an SD-Access network when DNA Center has IP connectivity to the devices and has the CLI and SNMP credentials required to manage the devices. These steps show how to initiate discovery by supplying an IP address range or multiple ranges to use to scan for network devices, which constrains the discovery and potentially saves time. Alternatively, you can supply an initial device for discovery and direct DNA Center to use Cisco Discovery Protocol to find connected neighbors. Step 1: Navigate to the main DNA Center dashboard, and at the bottom, under the Tools section, click Discovery and fill out a Discovery Name. Click Range, and enter a start and end IP loopback address for IP Ranges (to cover a single address, enter that address for both the start and end of the range). For Preferred Management IP, click + (plus sign), and then select Use Loopback. Step 2: If you have any additional ranges, in the IP Ranges section, enter the additional range, and then click + (plus sign). Verify the credentials to be used for the discovery, and then click Start. The discovery details are displayed and the discovery begins. A progress bar shows the status. During the discovery you can click the device count icon at the top of the page to see devices as they are discovered. Cisco Validated Design page 46 Deployment details Step 3: If there are any discovery failures, inspect the devices list, resolve the problem, and restart the discovery for those devices. Step 4: After the discovery process finishes successfully, navigate to the main DNA Center dashboard, and then, under the Tools section, click Inventory. The discovered devices are displayed. After inventory collection completes, the devices show a status of Managed. DNA Center can now access the devices, synchronize the inventory, and make configuration changes on the devices. Procedure 8 Configure underlay switches using LAN Automation Optional Use this procedure if you are deploying LAN switches without existing configurations into the underlay by using DNA Center’s LAN Automation capabilities. The device CLI and SNMP credentials to be pushed by Cisco Network Plug and Play (PnP), the network-reachable IP address pool used for connectivity, and the seed devices (typically border switches) have been configured as part of previous procedures. Each seed device is expected to have an appropriate VTP mode and MTU configuration (examples: vtp mode transparent, system mtu 9100). Ports connected to devices to be discovered must be in layer-2 mode, and cannot be dedicated out-of-band (OOB) management ports on a switch. Tech tip LAN Automation enables discovery of supported switches from supported seed devices (validated switches are listed in the appendix). Discovered switches are directly connected to chosen seed device interfaces (OOB management ports are not supported) and up to one additional hop of connected switches away. The credentials supplied allow DNA Center and seed devices to work together to configure the discovered devices and add them into managed inventory. Because all of the discovered devices must be running the PnP agent with no previous configuration, any previously configured switch to be used must be restored to a state where the PnP agent is running, accomplished by using the following commands: crypto key zeroize no crypto pki cert pool delete /force vlan.dat delete /force nvram:*.cer delete /force nvram:pnp* delete /force flash:pnp* Cisco Validated Design page 47 Deployment details delete /force stby-nvram:*.cer delete /force stby-nvram:*.pnp* !previous two lines only for HA systemswrite erase reload Do not save the configurations for the reload process. Step 1: Verify that the seed devices are in the inventory and managed by DNA Center. Step 2: Navigate to PROVISION > Devices > Inventory. At the top right, click LAN Automation, and fill in all of the parameters for the supported seed device. Select the interfaces connected to the devices to be discovered, and then click Start. Step 3: Click LAN Auto Status to view progress. Do not click Stop until all devices show a state of Completed. Prematurely stopping the PnP process will leave the discovery in a state needing manual intervention for recovery. Discovering devices an additional hop away from the seed can take significantly more time to reach completion. Tech tip The IP pool used for LAN Automation should be sized significantly larger than the number of devices to be discovered. The pool is divided in half, with one half used for VLAN 1 DHCP services provided by the seed devices. The second half of the pool is divided in half again, leaving a quarter of the total address space for point-to-point link addressing, and a quarter for loopback addressing. Endpoints should not be plugged into the switches, as they can exhaust the IP pool DHCP uses for PnP provisioning. Addresses in all pools need to be reachable by DNA Center to successfully complete provisioning. Step 4: After the devices discovered all reach Completed state, click Stop. LAN Automation tears down all Layer 2 connectivity on VLAN 1 and the underlay IS-IS routing process is used for reachability to the routed network, and devices can be managed just like other devices in the inventory. Procedure 9 Manage software images for devices in inventory To achieve the full capabilities of SD-Access, the SD-Access package in DNA Center has minimum software version requirements for the devices that it provisions. The software image management capability built into DNA Center is used to upgrade any devices that are not running a recommended image version. You can find recommended images by searching cisco.com for SD-Access Hardware and Software Compatibility Matrix. The images used for validation are listed in Appendix A: Product List. Use the following steps to apply software updates of images and software maintenance updates (SMUs) to the devices, by importing the required images, marking images as golden, and applying images to devices. Cisco Validated Design page 48 Deployment details Step 1: Navigate to the main DNA Center dashboard, click Design, click Image Repository, click + Import Image/SMU, choose a file location, and then click Import. The image import into DNA Center starts. Repeat this step for all images that you wish to deploy using DNA Center. Images to be used for device families not yet available in DNA Center will be listed under the Unassigned category. You can verify an import is in the image repository ready to deploy by clicking Show Tasks until the image import task is listed as green with a checkmark next to it. Step 2: After the image is successfully imported, use the Refresh button to update available device families that have the imported image available, under the Image Name column click the down arrow next to the image listed for a device family, and then click the star for Golden Image to mark the appropriate image as the preferred one for the platform. Repeat the importing and tagging images as golden until all devices are marked for an appropriate image. Procedure 10 Use software image management to update device software DNA Center runs a compliance check of devices in inventory compared to images marked golden. Devices out of compliance with the golden image are marked as Outdated in inventory. Update the images to the version marked golden. Inventory collection must have completed successfully and the devices must be in the Managed state before continuing. When you update device software, the software image copy and upgrade happen in a single step. Cisco Validated Design page 49 Deployment details Step 1: Navigate to PROVISION > Devices > Inventory, select all devices marked Outdated, select Actions, and then select Update OS Image. Step 2: Inspect the list of devices to be updated. If any devices do not have the appropriate resources for an upgrade, they are flagged. Fix any problems before continuing. Figure 3. Example device with insufficient flash memory available for update Step 3: Select all devices to update, use the default selection of Run Now, click Apply, and then at the popup warning about devices being rebooted click OK. Images are distributed to the selected devices, and then the devices reboot to activate the new images immediately after the image distribution is complete. Step 4: In Inventory, click Refresh to see overall upgrade status and click Upgrade Status to see the details for each task. Cisco Validated Design page 50 Deployment details Process Provisioning the SD-Access underlay network 1. Provision devices and assign to sites to prepare for SD-Access After devices have management connectivity with DNA Center and are running the appropriate software versions for SD-Access, use DNA Center to provision the devices with their roles as part of an SDAccess network. Procedure 1 Provision devices and assign to sites to prepare for SD-Access Provision the devices and assign devices to a site for integration into an SD-Access network. ISE is updated to support the provisioning. Tech tip When devices are provisioned, the devices receive a number of configurations appropriate for the assigned site, including the centralized AAA server configuration, which is preferred over local login credentials. To maintain the ability to manage the devices after provisioning, the credentials you use for provisioning must be available from the centralized AAA server, either directly or as the means to an external identity source such as Active Directory. Step 1: Log in to ISE, navigate to Administration > Identity Management > Identities, click +Add, enter the Name (matching what was used for DNA Center discovery), enter the associated Login Password and Re-Enter Password, and then at the bottom of the screen click Submit. The network administrative user login is now available from ISE, in addition to the same user ID stored on each device. Cisco Validated Design page 51 Deployment details Step 2: In DNA Center, navigate to PROVISION > Devices > Inventory, select the devices to provision into an SD-Access network, click Actions, and then click Provision. A Provision Devices wizard screen appears. Tech tip Devices must be of the same type (example: all switches) in order to provision them at the same time. You can group provisioning operations in multiple small batches for common site assignments as needed. Step 3: Within the first wizard screen, select the site assignments for the devices, and then at the bottom of the screen click Next. Cisco Validated Design page 52 Deployment details Step 4: Use Next to skip the Configuration and Advanced Configuration screens, in the Summary screen review the details for each device, and then click Deploy. Step 5: At pop-up screen, leave the default selection of Now, and click Apply. Configuration of each device begins, and status messages appear as each device is provisioned successfully. The Device Inventory screen updates with Provision Status and Sync Status. As a result of the DNA Center pxGrid integration with ISE, the network devices also appear in ISE. Step 6: Verify the ISE integration function by logging into ISE and navigating to Administration > Network Resources > Network Devices. The provisioned devices appear. Cisco Validated Design page 53 Deployment details Process Provisioning an SD-Access overlay network 1. Create a fabric domain and add provisioned network devices 2. Enable eBGP connectivity for VN at neighbor (fusion) to border router 3. Assign wired clients to VN and enable connectivity 4. Enable fabric edge ports for client onboarding 5. Enable multicast for fabric Create a fabric overlay network using the provisioned SD-Access underlay network devices. Procedure 1 Create a fabric domain and add provisioned network devices A fabric domain called Default LAN Fabric is automatically created by DNA Center, containing provisioned devices ready to be assigned to a fabric. Create a new campus fabric domain and assign the appropriate devices to it. Campus fabric domains are used in the SD-Access 1.1 solution, enabling client endpoints to connect to wired and wireless LAN networks. Step 1: Using DNA Center, navigate to PROVISION > Fabric, click + Add, leave the default Campus selection, supply a fabric name (example: RTP6_C9K), and then click Add. The new campus fabric domain is created. Tech tip All devices appear across all fabric domains. The fabric is defined within a domain by assigning fabric functionality to devices and requires at least one instance of each of the fabric functions: edge node, border node, and control plane. The roles may be combined (example: control plane and border node) as permitted by the SD-Access solution being deployed. Cisco Validated Design page 54 Deployment details Step 2: Click the icon for the fabric domain you just created (example: RTP6_C9K). The fabric Select Devices wizard starts. Step 3: If the topology diagram shown does not mimic the two-tier (distribution/access) or three-tier (core/ distribution/access) topology that is deployed, correct the topology by clicking each device, on the pop-up menu select Device Role, inspect its network role, and then either change the role and click Save, or if the role is correct select Cancel. When the device roles are complete an appropriate topology is displayed. The topology can be reoriented by clicking the green arrow button. Step 4: Hold the shift key and click all of the nodes that are fabric edge nodes, and then in the pop-up box, click Add to Fabric. Step 5: If you have a node for the fabric dedicated to the role of being a control plane node without border functionality, click it, and then in the pop-up box, click Add as CP (control plane). Repeat this step for a redundant dedicated control plane node without border functionality. Tech tip If the border nodes are Cisco Nexus® 7700 Series Switches using the software listed in Appendix A: Product List, you use dedicated control plane nodes and connect them directly to the Nexus 7700 Series border nodes. Additionally, enable the MPLS license and configure MPLS LDP on the physical links to the control plane nodes to support the control plane connectivity. Cisco Validated Design page 55 Deployment details Step 6: Click a device to perform the fabric border role, in the pop-up box click either Add as Border or Add as CP+Border (if skipping the previous step), fill in the additional dialog for the type of border (example: Outside World (External)), supply the BGP Local AS Number (example: 65514), under Border Handoff > Layer 3 use the Select IP Pool dropdown to select the Global pool configured previously in the guide for border connectivity functionality, and then next to External Interface click + Add Interface. Tech tip If the border is the only path to exit to the rest of the network, you should choose an external border. In cases where you have a combined control plane and border node functionality and the node uses internal border functionality, additional control plane filtering may be necessary when using the validated releases shown in Appendix A: Product List. Step 7: Select the interface for the connection to the fusion router outside of the fabric, fill in the BGP Remote AS Number for the device outside of the fabric (example: 65500), select Virtual Network and all VNs to include in the Layer 3 handoff outside the fabric, click Save, and then click Add. If you have an additional fabric border node, repeat the previous two steps for it. Tech tip To configure a VRF-Lite handoff interface from the border to the rest of the network requires an 802.1Q-tagged interface. If you are managing the border using in-band connectivity over the redundant links to be converted, you first make the connection over a tagged interface, as described in the processes to setup management to a border device for network discovery. When using the version of SD-Access validated in this guide, provisioning is unsuccessful if the interface already includes a non-tagged configuration. Cisco Validated Design page 56 Deployment details Step 8: After all required roles are assigned to the nodes in the fabric, at the bottom click Save, use the default choice Now, and then click Apply. Your campus fabric domain is created. Procedure 2 Enable eBGP connectivity for VN at neighbor (fusion) to border router The SD-Access application in DNA Center configures the fabric border node BGP handoff to external networks. In the SD-Access version validated, you manually configure the external network peers of the border devices with the compatible VRF-Lite and BGP peering information. For AP and other infrastructure onboarding, you use the routing information from the BGP peer for the DEFAULT_VN, highlighted in the example below. Example subset of border node configuration pushed by DNA Center SD-Access application vrf definition DEFAULT_VN rd 1:4098 ! address-family ipv4 route-target export 1:4098 route-target import 1:4098 exit-address-family ! vrf definition Workers rd 1:4099 ! address-family ipv4 route-target export 1:4099 route-target import 1:4099 exit-address-family Cisco Validated Design page 57 Deployment details ! interface Vlan3001 description vrf interface to External router ip address 172.16.172.1 255.255.255.252 no ip redirects ip route-cache same-interface ! interface Vlan3002 description vrf interface to External router vrf forwarding Workers ip address 172.16.172.5 255.255.255.252 no ip redirects ip route-cache same-interface ! interface Vlan3003 description vrf interface to External router vrf forwarding DEFAULT_VN ip address 172.16.172.9 255.255.255.252 no ip redirects ip route-cache same-interface ! router bgp 65514 bgp router-id interface Loopback0 bgp log-neighbor-changes neighbor 10.4.2.65 remote-as 65500 neighbor 10.4.14.4 remote-as 65514 neighbor 10.4.14.4 update-source Loopback0 neighbor 172.16.172.2 remote-as 65500 neighbor 172.16.172.2 update-source Vlan3001 Cisco Validated Design page 58 Deployment details ! address-family ipv4 network 10.4.14.3 mask 255.255.255.255 aggregate-address 10.4.14.0 255.255.255.0 summary-only redistribute isis level-2 redistribute lisp metric 10 neighbor 10.4.2.65 activate neighbor 10.4.14.4 activate neighbor 172.16.172.2 activate neighbor 172.16.172.2 weight 65535 exit-address-family ! address-family ipv4 vrf DEFAULT_VN redistribute lisp metric 10 neighbor 172.16.172.10 remote-as 65500 neighbor 172.16.172.10 update-source Vlan3003 neighbor 172.16.172.10 activate neighbor 172.16.172.10 weight 65535 exit-address-family ! address-family ipv4 vrf Workers redistribute lisp metric 10 neighbor 172.16.172.6 remote-as 65500 neighbor 172.16.172.6 update-source Vlan3002 neighbor 172.16.172.6 activate neighbor 172.16.172.6 weight 65535 exit-address-family ! The deployed configuration includes VRF, VLAN, and BGP elements similar to the ones shown in the above configuration example; however, the VLANs deployed will likely be different. Cisco Validated Design page 59 Deployment details Step 9: Login to border devices and use the CLI to observe the automated configurations created by the SD-Access DNA Center application for IP connectivity outside of the border. Some of the following commands may be helpful. show running-config brief show running-config | section vrf definition show running-config | section interface Vlan show running-config | section router bgp Tech tip There are other important additions to the configuration, which are handled completely by the automation. If you are interested in observing additional LISP fabric control plane changes, use the following command: show running-config | section LISP|lisp|site Step 10: Login to the fusion devices external to the fabric that are connected to the border, using the border configuration as a guide, configure VRFs as required by virtual networks created on the border. VRFs separate communication between groups of interfaces and virtual network contexts within the fabric. vrf definition [VRF name] rd [Route Distinguisher] address-family ipv4 route-target export [Route Target] route-target import [Route Target] exit-address-family Repeat this step for each virtual network context, consistent with the border node configuration. Step 11: Configure each interface to the neighbor. Some devices support VLAN subinterface configuration directly on trunks, and other devices require VLAN interfaces to be created and associated with a trunk. Repeat the neighbor interface configuration for each neighbor on each peer to the border. interface [Peer interface] Step 12: Configure BGP IPv4 unicast routing towards the fusion router to support connectivity for each VRF associated with each VN in the fabric. router bgp [Local BGP AS] bgp router-id interface Loopback0 bgp log-neighbor-changes neighbor [Border IP Address] remote-as [Fabric BGP AS] !repeat for any additional neighbors Cisco Validated Design page 60 Deployment details ! address-family ipv4 network [Loopback IP Address] mask 255.255.255.255 neighbor [Border 1 IP Address] activate neighbor [Border 2 IP Address] activate maximum-paths 2 exit-address-family Procedure 3 Assign wired clients to VN and enable connectivity Step 1: From the DNA Center dashboard, navigate to PROVISION > Fabric > Host Onboarding, under Select Authentication template select Closed Authentication, at the top of the section click Save, and then click Apply. Step 2: Under Virtual Networks, select a VN to be used for wired clients (example: Workers), in the Edit Virtual Network:Workers slide-out pane, select the names of IP Pools to add to the VN (example: 14-Employee), select Traffic Type of Data, change Layer 2 Extension to Off, and then click Update. Layer 2 extension is only supported with wireless in SD-Access solution 1.1. Cisco Validated Design page 61 Deployment details Step 3: At the Modify Authentication Template slideout, keep the default Run Now selection, and then click Apply. Procedure 4 Enable fabric edge ports for client onboarding Repeat this procedure for each fabric edge switch where clients are connecting. Step 1: Navigate to PROVISION > Fabric > Host Onboarding. Under Select Port Assignment in the left column, select a switch. Step 2: At the top of the list of switch ports on the right, select the Address Pool(VN) (example: 10_101_114_0-Workers). Optionally select an appropriate group from Groups (example: Employees), optionally select a Voice Pool(VN) to use for IP telephones, and then select the Authentication (example: Closed Authentication). Tech tip The group assignment is used to statically assign a group if the fabric edge port does not receive its assignment dynamically using an authentication server, which is useful for some types of devices used in an organization. If “No Authentication” is selected as an authentication method, DNA Center pushes the global default authentication template chosen in the “Select Authentication template” section at the top of the screen. DNA Center pushes a port configuration when “Closed Authentication” is configured. Cisco Validated Design page 62 Deployment details Step 3: Within the list of switch ports, select every wired fabric edge port to participate in the fabric VN, click Save, and then click Apply. Devices can now connect at the fabric edge ports using the wired network overlay and authentication method created. Example port configuration pushed by DNA Center using closed authentication interface GigabitEthernet1/0/23 switchport access vlan 1032 switchport mode access switchport voice vlan 1030 load-interval 30 authentication control-direction in authentication event server dead action authorize vlan 3999 authentication event server dead action authorize voice authentication host-mode multi-auth authentication order dot1x mab authentication priority dot1x mab authentication port-control auto authentication periodic authentication timer reauthenticate server authentication timer inactivity server dynamic mab no macro auto processing dot1x pae authenticator dot1x timeout tx-period 10 spanning-tree portfast Cisco Validated Design page 63 Deployment details Procedure 5 Enable multicast for fabric Optional Use this procedure to configure multicast support in the fabric overlay. SD-Access fabrics can support Any Source Multicast (ASM) and Source Specific Multicast (SSM). Sources can be within the fabric or outside of the fabric, and Rendezvous Point configuration is available only at the fabric border nodes. PIM messages are unicast between the border nodes and the fabric edges, and multicast packets are replicated at the head end fabric border devices toward the fabric edge nodes. Step 1: Add a global pool in DNA Center that is dedicated for unicast IP interfaces used to enable multicast for each VN where multicast is enabled. Navigate to DESIGN > Network Settings > IP Address Pools. In the site hierarchy on the left, select Global. Click + Add IP Pool, and fill in the IP Pool Name, IP Subnet, CIDR Prefix, and Gateway IP address. Assign DHCP Server(s) and DNS Server(s). Do not select Overlapping. When you are done, click Save. Step 2: Using DNA Center, navigate to PROVISION > Fabric, and click the icon for the fabric domain. The fabric Select Devices wizard starts. Step 3: Right-click on a fabric border node and select Enable Rendezvous Point. Within the Associate Multicast Pools to VNs popup window at the right, under Associate Virtual Networks, choose the VN. Under Select IP Pools, choose the pool created for multicast, and click the plus sign to add the pool to the list. Click Next, and then click Enable. Step 4: Repeat the previous step for any additional fabric border nodes. At the bottom of the screen, click Save, and then click Apply. DNA Center pushes the multicast configurations to the fabric nodes and creates the loopbacks and Multicast Source Discovery Protocol (MSDP) peering for the rendezvous point (RP) state communication between the border nodes. Step 5: If multicast communication is required outside of the border toward the fusion router, enable the following commands on each device. Global: ip multicast-routing ip pim rp address [RP Address] ip pim register-source Loopback0 ip pim ssm default Interface or subinterface (for each virtual network): ip pim sparse-mode Cisco Validated Design page 64 Deployment details Process Integrating wireless into SD-Access 1.

Procedure 3 Design fabric enterprise wireless SSIDs Step 1: From the main DNA Center dashboard, navigate to DESIGN > Network Settings> Wireless, in the Enterprise Wireless section click + Add, in the Create an Enterprise Wireless Network wizard, and supply the following information: • Enter the Wireless Network Name(SSID) (example: Employee) • Under TYPE OF ENTERPRISE NETWORK, select Voice and Data and Fast Lane • For LEVEL OF SECURITY select WPA2 Enterprise • Under ADVANCED SECURITY OPTIONS select Adaptive Step 2: Click Next to continue in the wizard, and supply the following information: • Enter a Wireless Profile Name (example: RTP5-Wireless) • Under Fabric, select Yes • Under Choose a site, select the location where the SSID will broadcast (example: Global/RTP/RTP5-C9K), and include floors to include in SSID coverage (example: Global/RTP/RTP5-C9K/Main Floor) Step 3: Click Finish to continue. The DESIGN > Network Settings> Wireless screen is displayed. Repeat this procedure for additional SSIDs using the same network profile and any new location profiles to be associated with an SSID. Procedure 4 Design a fabric guest wireless SSID Step 1: Navigate to DESIGN > Network Settings> Wireless, in the Guest Wireless section click + Add, in the Create a Guest Wireless Network wizard, and supply the following information: • Enter the Wireless Network Name(SSID) (example: Guest) • Under LEVEL OF SECURITY select Web Auth • Under AUTHENTICATION SERVER select ISE Authentication Leave the other default selections and click Next to continue in the wizard. Cisco Validated Design page 67 Deployment details Step 2: In the Wireless Profiles section, select the Profile Name corresponding to the deployment location (example: RTP5-Wireless), in the slide-out panel keep the default Fabric selection of Yes, keep the other default information, at the bottom of the panel click Save, and then click Next. Step 3: In the Portals screen, click + Add. The Portal Builder screen appears. Step 4: Supply a Guest Portal name (example:Guest-RTP5), make any desired customizations, and then at the bottom of the screen click Save. A guest web authentication portal is generated for the site, and you return to the previous screen. Step 5: Click Finish. The wireless LAN design is created and is ready to deploy. Procedure 5 Provision the WLC for SD-Access Wireless fabric integration After completing the SD-Access Wireless design, push the configuration from the design to the WLC. Step 1: Navigate to PROVISION > Devices, find the WLC and select the checkbox next to it, and then at the top of the screen under the Actions pull-down, select Provision. The Provision Devices wizard opens. Step 2: Assign the site (example: Global/RTP/RTP5-C9K), click Next, at the Configuration screen under Managed AP Location select the additional floor assignments for APs managed by the WLC (example: Global/ RTP/RTP5-C9K/Main Floor), click Next, and then at the Advanced Configuration screen click Next. Step 3: At the Summary screen review the configurations, click Deploy, at the slide-out panel keep the default selection Run Now, and then click Apply. The WLC is assigned to the site and the provisioning starts. Use the Refresh button until Provision Status shows Success before proceeding. Cisco Validated Design page 68 Deployment details Step 4: Navigate to PROVISION > Fabric, click the fabric domain where the WLC is to be added (example: RTP6_C9K), click the WLC, in the popup box select Add to Fabric, click Save, in the slide-out menu keep the default selection Run Now, and then click Apply. The WLC configurations are created to establish a secure connection to the fabric control plane. You can verify that WLC controller pair is integrated into the fabric from the WLC management console by navigating to CONTROLLER > Fabric Configuration > Control Plane, which shows the fabric integration is enabled with the connection status up. Cisco Validated Design page 69 Deployment details Procedure 6 Enable onboarding of access points into the wireless fabric The APs are hosts that join the fabric and are assigned into a VN named INFRA_VN. This special VN for infrastructure devices such as APs, enables management communication between the APs at the fabric edge nodes using the fabric control plane and the WLC sitting outside of the fabric as a part of global routing connectivity. Step 1: Connect APs to be used for the fabric directly to an edge node within the fabric. Step 2: Navigate to PROVISION > Fabric, select the fabric, and then click Host Onboarding. Step 3: Under Select Authentication template, select No Authentication, click Save, in the slide-out panel keep the default selection Run Now and then click Apply. The authentication template is applied to the fabric, and automatic onboarding of APs is enabled. Tech tip DNA Center enables automatic onboarding of APs by provisioning a CDP macro at the fabric edge switches when the authentication template to be set to No Authentication. Alternatively, you use the switch port configurations in DNA Center to assign a port to the IP address pool for the APs. Step 4: Under Virtual Networks, select INFRA_VN, click the check box next to the IP Pool Name for the APs (example: Access-Point), click Update, in the slide-out panel keep the default selection Run Now, and then click Apply. After the update is complete, the edge node switch ports connected to the APs are enabled with a device tracking configuration recognizing APs and permitting the APs to get network connectivity. Tech tip A default route in the underlay cannot be used by the APs to reach the WLC. A more specific route (such as a /24 subnet or /32 host route) to the WLC IP addresses must exist in the global routing table at each node where the APs connect to establish connectivity. Redistribute the WLC route at the border into the underlay IGP routing process for efficiency. Alternatively, you can create static entries at each edge node supporting APs.

This IC can be programmed to operate in either a constant frequency or constant off-time mode. It includes a 15 – 450V linear regulator which allows it to work with a wide range of input voltages without the need for an external low voltage supply. HV9910C includes a TTL-compatible, PWM-dimming input that can accept an external control signal with a duty ratio of 0 – 100% and a frequency of up to a few kilohertz. It also includes a 0 – 250mV linear-dimming input which can be used for linear dimming of the LED current. Unlike the HV9910B, the HV9910C is equipped with built-in thermal-shutdown protection. HV9910C is ideally suited for buck LED drivers. Since the HV9910C operates in open-loop current mode control, the controller achieves good output current regulation without the need for any loop compensation. Also, being an open-loop controller, PWM-dimming response is limited only by the rate of rise of the inductor current, enabling a very fast rise and fall times of the LED current. HV9910C requires only three external components (apart from the power stage) to produce a controlled LED current. This makes HV9910C an ideal solution for low-cost LED drivers.

DS20005323A-page 7 HV9910C 3.0 APPLICATION INFORMATION HV9910C is optimized to drive buck LED drivers using open-loop, peak-current mode control. This method of control enables fairly accurate LED current control without the need for high side current sensing or the design of any closed loop controllers. The IC uses very few external components and enables both Linear and PWM-dimming of the LED current. A resistor connected to the RT pin programs the frequency of operation (or the off-time). The oscillator produces pulses at regular intervals. These pulses set the SR flip-flop in the HV9910C which causes the GATE driver to turn on. The same pulses also start the blanking timer, which inhibits the reset input of the SR flip flop and prevents false turn-offs due to the turn-on spike. When the FET turns on, the current through the inductor starts ramping up. This current flows through the external sense resistor, RCS, and produces a ramp voltage at the CS pin. The comparators are constantly comparing the CS pin voltage to both the voltage at the LD pin and the internal 250mV. Once the blanking timer is complete, the output of these comparators is allowed to reset the flip-flop. When the output of either one of the two comparators goes high, the flip-flop is reset and the GATE output goes low. The GATE goes low until the SR flip-flop is set by the oscillator. Assuming a 30% ripple in the inductor, the current sense resistor RCS can be set using: Constant frequency peak current mode control has an inherent disadvantage – at duty cycles greater than 0.5, the control scheme goes into subharmonic oscillations. To prevent this, an artificial slope is typically added to the current sense waveform. This slope compensation scheme will affect the accuracy of the LED current in the present form. However, a constant offtime peak current control scheme does not have this problem and can easily operate at duty cycles greater than 0.5. This control scheme also gives inherent input voltage rejection, making the LED current almost insensitive to input voltage variations. However, this scheme leads to variable frequency operation and the frequency range depends greatly on the input and output voltage variation. Using HV9910C, it is easy to switch between the two modes of operation by changing one connection (see Section 3.3 “Oscillator”). 3.1 Input Voltage Regulator HV9910C can be powered directly from its VIN pin and can work from 15 - 450VDC at its VIN pin. When a voltage is applied at the VIN pin, HV9910C maintains a constant 7.5V at the VDD pin. This voltage is used to power the IC and any external-resistor dividers needed to control the IC. The VDD pin must be bypassed by a low-ESR capacitor to provide a low impedance path for the high frequency current of the output GATE driver. HV9910C can also be operated by supplying a voltage at the VDD pin greater than the internally regulated voltage. This will turn off the internal linear regulator of the IC and the HV9910C will operate directly off the voltage supplied at the VDD pin. This external voltage at the VDD pin should not exceed 12V. Although the VIN pin of the HV9910C is rated up to 450V, the actual maximum voltage that can be applied is limited by the power dissipation in the IC. For example, if an 8-lead SOIC HV9910C (junction to ambient thermal resistance Rθj-a = 101°C/W) draws about IIN = 2.0mA from the VIN pin, and has a maximum allowable temperature rise of the junction temperature limited to ∆T = 75°C, the maximum voltage at the VIN pin would be: In these cases, to operate HV9910C from higher input voltages, a Zener diode can be added in series with the VIN pin to divert some of the power loss from HV9910C to the Zener diode. In the above example, using a 100V Zener diode will allow the circuit to easily work up to 450V. The input current drawn from the VIN pin is a sum of the 1.5mA (maximum) current drawn by the internal circuit and the current drawn by the GATE driver. The GATE driver depends on the switching frequency and the GATE charge of the external FET. In the above equation, fs is the switching frequency and Qg is the GATE charge of the external FET, which can be obtained from the data sheet of the FET. 3.2 Current Sense The current sense input of HV9910C goes to the noninverting inputs of two comparators. The inverting terminal of one comparator is tied to an internal 250mV reference, whereas the inverting terminal of the other comparator is connected to the LD pin. The outputs of both these comparators are fed into an OR GATE and RCS 0.25V orV   LD 1.15 I  LED = ------------------------------------ Note: The Zener diode will increase the minimum input voltage required to turn on the HV9910C to 115V.

Thus, the comparator which has the lowest voltage at the inverting terminal determines when the GATE output is turned off. The outputs of the comparators also include a 150- 280ns blanking time which prevents spurious turn-offs of the external FET due to the turn-on spike normally present in peak-current mode control. In rare cases, this internal blanking might not be enough to filter out the turn-on spike. In these instances, an external RC filter needs to be added between the external sense resistor (RCS) and the CS pin. Please note that the comparators are fast (with a typical 80ns response time). A proper layout minimizing external inductances will prevent false triggering of these comparators. 3.3 Oscillator The oscillator in HV9910C is controlled by a single resistor connected at the RT pin. The equation governing the oscillator time period Tosc is given by: If the resistor is connected between RT and GND, HV9910C operates in a constant frequency mode and the above equation determines the time period. If the resistor is connected between RT and GATE, HV9910C operates in a constant off-time mode and the above equation determines the off-time. 3.4 Gate Output The gate output of the HV9910C is used to drive an external FET. It is recommended that the GATE charge of the external FET be less than 25nC for switching frequencies ≤ 100kHz and less than 15nC for switching frequencies > 100kHz. 3.5 Linear Dimming The Linear Dimming pin is used to control the LED current. There are two cases when it may be necessary to use the Linear Dimming pin. 1. In some cases, when using the internal 250mV, it may not be possible to find the exact RCS value required to obtain the LED current. In these cases, an external voltage divider from the VDD pin can be connected to the LD pin to obtain a voltage (less than 250mV) corresponding to the desired voltage across RCS. 2. Linear dimming may be desired to adjust the current level to reduce the intensity of the LEDs. In these cases, an external 0-250mV voltage can be connected to the LD pin to adjust the LED current during operation. To use the internal 250mV, the LD pin can be connected to VDD. 3.6 PWM Dimming PWM Dimming can be achieved by driving the PWMD pin with a low frequency square wave signal. When the PWM signal is zero, the GATE driver is turned off; when the PWMD signal if high, the GATE driver is enabled. The PWMD signal does not turn off the other parts of the IC, therefore, the response of HV9910C to the PWMD signal is almost instantaneous. The rate of rise and fall of the LED current is thus determined solely by the rise and fall times of the inductor current. To disable PWM Dimming and enable the HV9910C permanently, connect the PWMD pin to VDD. 3.7 Over-Temperature Protection The auto-recoverable thermal shutdown at 140°C (typ.) junction temperature with 20°C hysteresis is featured to avoid thermal runaway. When the junction temperature reaches TSD = 140°C (typ.), HV9910C enters a low power consumption shut-down mode with IIN <350µA. TOSC  s ROSC  k 25 = -------------------------- Note: Although the LD pin can be pulled to GND, the output current will not go to zero. This is due to the presence of a minimum ontime, which is equal to the sum of the blanking time and the delay to output time, or about 450ns. This minimum on-time causes the FET to be on for a minimum of 450ns, and thus the LED current when LD = GND is not zero. This current is also dependent on the input voltage, inductance value, forward voltage of the LEDs, and circuit parasitics. To get zero LED current, the PWMD pin has to be used.  2014 Microchip Technology Inc.

Step 4 framing {sf | esf} or framing {crc4 | no-crc4} Example: Router(config-controller)# framing esf In T1 configurations, specifies super frame (sf) or extended super frame (esf) as the frame type for data lines. Default is esf. In E1 configurations, specifies cyclic redundancy check 4 (crc4) or no-crc4 as the frame type for data lines. Default is crc4. Step 5 linecode {ami | b8zs} or linecode {ami | hdb3} Example: Router(config-controller)# linecode b8zs In T1 configurations, specifies alternate mark inversion (AMI) or bipolar 8-zero substitution (b8zs) as the linecode. Default is b8zs. In E1 configurations, specifies AMI or high-density bipolar 3 (hdb3) as the linecode. Default is hdb3. Note When using linecode AMI, we recommend that you select 56 kbps as the speed or make sure that the channel groups created do not contain all the timeslots. See Step 11. This is to avoid exceeding the “15 zeroes” threshold specified by standards. Step 6 fdl {att | ansi | both} Example: Router(config-controller)# fdl both T1 only. Sets the facility data link (fdl) exchange standard for T1 interfaces using esf framing. You can select the ATT standard (ATT TR54016), the ANSI standard (ANSI T1.403), or both standards. Default is ansi. To disable fdl, enter the no fdl command. Command or Action Purpose 7 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 7 clock source {internal | line [primary | secondary] | network} Example: Router(config-controller)# clock source network Specifies the clock source. The options are as follows: • internal—Sets the controller framer as the clock master. The clock source internal command is only applicable with the channel-group command and the pri-group (for data) command. Note The pri-group command is supported on the NIM-xCE1T1-PRI for data without the keyword voice-dsp. • line—Specifies the phase-locked loop (PLL) on a port. When both a primary port and a secondary port are configured and the primary port fails, the PLL switches over to the secondary. When the PLL on the primary port becomes active again, the PLL automatically switches to the primary port. • network—Sets the controller to sync to the TDMSW clock for both TDM voice and data support. This configures the far end of the T1/E1 line as the clock line. Default is line. Step 8 line-termination {75-ohm | 120-ohm} Example: Router(config-controller)# line-termination 75-ohm E1 only. Sets the line termination on an E1 controller. • 75-ohm specifies 75-ohm unbalanced termination. • 120-ohm specifies 120-ohm balanced termination. Step 9 loopback {diagnostic | local {payload | line} | remote {iboc | esf {payload | line}}} Example: Router(config-controller)# loopback remote esf line Sets the loopback method for testing the interface. Options are: • diagnostic—Loops the transmit signal back to receive. • local—Puts the interface into local loopback mode at the payload or line level. • remote—Puts the interface into remote loopback mode through an inband bit oriented code (iboc) or, for T1 only, remote esf, which uses fdl codes to set payload or line levels. Command or Action Purpose 8 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 10 cablelength long db-loss-value or cablelength short length Example: Router(config-controller)# cablelength short 110 T1 only.The cablelength long command attenuates the pulse from the transmitter using pulse equalization and line build-out. This command applies to cables longer than 660 feet. Loss values are: • 0db • -7.5db • -15db • -22.5db Default attenuation is 0db. The cablelength short command sets transmission attenuation for cable lengths of 660 feet or less. When you use the cablelength short command, specify the length as follows: • 110 for cable lengths from 0 to 110 feet • 220 for cable lengths from 111 to 220 feet • 330 for cable lengths from 221 to 330 feet • 440 for cable lengths from 331 to 440 feet • 550 for cable lengths from 441 to 550 feet • 660 for cable lengths from 551 to 660 feet There is no default cable length. Step 11 channel group channel-group-number {timeslots range [speed kbps] | unframed} Example: Router(config-controller)# channel group 1 timeslots 1-4 Configures the serial WAN on a T1 or E1 interface by specifying channels and their timeslots. For T1, values are as follows: • channel-group-number is from 0 to 23. • timeslots range is from 1 to 24. • Default value of speed for T1 is 64 kbps. Configuration of speed is optional. For E1, values are as follows: • channel-group-number is from 0 to 30. • timeslots range is from 1 to 31. • Default value of speed for E1 is 64 kbps. Configuration of speed is optional. • unframed (E1 only) specifies that all 31 timeslots are to be used for data and that none are to be used for framing signals.

Defines a severely errored second by specifying the number of CRC errors that must occur in one second to reach the severely errored second state. Default is 320. Step 14 yellow {generation | detection} Example: Router(config-controller)# no yellow detection Enables generation and detection of yellow alarms. Default condition is that generation and detection of yellow alarms are enabled. Use the no form of the command to disable yellow alarm detection. Step 15 bert pattern pattern interval time Example: Router(config-controller)# bert pattern 2^11 interval 1440 (Optional) Activates the BERT with the chosen test pattern for a specified duration. Configure BERT patterns on the T1/E1 network interface modules as follows: • When the linecode is AMI, use patterns 2^11, 2^15, or 2^20-QRSS. • When the linecode is b8zs or hdb3, use patterns 2^11, 2^15, 2^20-QRSS, or 2^20-O.153. • The interval time is from 1 to 14,400 minutes.

Step 2 configure terminal Example: Router# configure terminal Enters global configuration mode. Step 3 voice-card slot/subslot Example: Router(config)# voice-card 0/1 Enters voice card interface configuration mode. • Specify the slot location using a value from 0 to 5. 11 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 4 codec complexity {flex [reservation-fixed {high | medium}] | high | medium | secure} Example: Router(config-voicecard)# codec complexity flex Specifies the codec complexity based on the codec standard that you are using. The number of calls that is supported on the router is dependent on the DSP density and the codec complexity. • flex—Provides support for both medium and high-complexity codec. The number of supported calls varies depending on the codec that is used for a call. In this mode, oversubscription of DSPs is possible. If reservations are needed for certain applications such as CAMA E-911 calls, you can enable the reservation-fixed option. There is no reservation by default. • high—Supports G.711, G.726, G.729, G.723.1, G.723.1 Annex A, G.729 Annex B, G.728, and GSMEFR. • medium—Supports G.711, G.726, G.729 Annex A, G.729 Annex B with Annex A, GSMFR, and fax relay. • secure—Specifies secure codec. Note All medium-complexity codecs are supported in high-complexity codecs. The keyword that you specify for the codec complexity command affects the codecs available when you use the codec dial peer voice configuration command. If you select a codec that is not available, an error message appears. • You cannot change codec complexity while DS0 groups are defined. If they are already set up, follow these steps: 1. Shut down the voice port associated with the controller. 2. Enter the voice-card slot command, and then change the codec complexity. Note This procedure to change codec complexity applies only to T1 and E1 controllers. This procedure is not valid for analog voice ports. Step 5 exit Example: Router(config-voicecard)# exit Exits voice card configuration mode and returns to global configuration mode. Step 6 controller {e1 | t1} slot/subslot/port Example: Router(config)# controller t1 0/1/1 Enters controller configuration mode for the network interface module. • Valid values for slot is 0, subslot is 1 to 3, and port is 0 to 7. Command or Action Purpose 12 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 7 framing {sf | esf} or framing {crc4 | no-crc4} Example: Router(config-controller)# framing esf Example: Router(config-controller)# framing crc4 Specifies a frame type. • The frame type for T1 controllers can be specified as sf for superframe or esf for extended superframe. • The frame type for E1 controllers can be specified as crc4 or no-crc4. Step 8 linecode {ami | b8zs} or linecode {ami | hdb3} Example: Router(config-controller)# linecode b8zs Example: Router(config-controller)# linecode hdb3 Specifies a line encoding for a controller. • Line-code value for T1 can be ami or b8zs. • Line-code value for E1 can be ami or hdb3. Command or Action Purpose 13 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 9 ds0-group ds0-group-number timeslots timeslot-list type {e&m-delay-dial | e&m-immediate-start | e&m-wink-start | fxo-ground-start | fxo-loop-start | fxs-ground-start | fxs-loop-start} Example: Router(config-controller)# ds0-group 12 timeslots 1-3 type fxs-loop-start Defines the T1 channels for use by compressed voice calls and the signaling method that the router uses to connect to the PBX or central office. • Set up DS0 groups after you have specified codec complexity in the voice-card configuration. • ds0-group-number—Value from 0 to 23 that identifies the DS0 group. • The ds0-group command automatically creates a logical voice port that is numbered as follows: slot/port:ds0-group-number. Although only one voice port is created, applicable calls are routed to any channel in the group. • The timeslot-list argument is a single number, numbers separated by commas, or a pair of numbers separated by a hyphen to indicate a range of time slots. • The signaling method selection for the type keyword depends on the connection that you are making: – The E&M interface allows connection for PBX trunk lines (tie lines) and telephone equipment. – The Foreign Exchange Station (FXS) interface allows connection of basic telephone equipment and PBX. – The Foreign Exchange Office (FXO) interface is for connecting the CO to a standard PBX interface where permitted by local regulations; it is often used for off-premises extensions (OPXs). Step 10 clock source {line [primary | secondary] | network} Example: Router(config-controller)# clock source network Specifies the clock source. For voice, you can select either line or network. If internal clocking is required on the network interface module, configure clock source network. • line—Specifies the phase-locked loop (PLL) on a port. When both a primary port and a secondary port are configured and the primary port fails, the PLL switches over to the secondary. When the PLL on the primary port becomes active again, the PLL automatically switches to the primary port. • network—Sets the controller to sync to the TDMSW clock for both TDM voice and data support. This configures the far end of the T1/E1 line as the clock line. Command or Action Purpose 14 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 11 tdm-group tdm-group-no timeslots timeslot-list type [e&m | fxs [loop-start | ground-start] | fxo [loop-start | ground-start]] Example: Router(config-controller)# tdm-group 20 timeslots 20 type fxs ground-start (Optional) Defines TDM channel groups for the drop-and-insert (also called TDM Cross-Connect) function for a multiflex trunk interface card. The tdm-group-no argument identifies the TDM group and is a value from 0 to 23 for T1 and from 0 to 30 for E1. The timeslot-range argument indicates a range of time slots and is a single number, numbers separated by commas, or a pair of numbers separated by a hyphen. The valid range is from 1 to 24 for T1 and from 1 to 31 for E1. The signaling method selection for the type keyword depends on the connection that you are making. The fxs and fxo options allow you to specify a ground-start or loop-start line. Note The group numbers for controller groups must be unique. For example, a TDM group should not have the same ID number as a DS0 group or channel group. Step 12 voice-port {slot-number/subunit-number/port | slot/port:ds0-group-number} Example: Router(config-controller)# voice-port 3/0:0 Enters voice port configuration mode and specifies the voice port. • The slot-number argument identifies the slot where the NIM is installed. Valid entries are from 0 to 3. • The subunit-number argument identifies the subunit on the NIM where the voice port is located. Valid entries are 0 or 1. • The port argument identifies the voice port number. Valid entries are 0 and 1. or • The slot argument is the slot in which the voice port adapter is installed. Valid entries are from 0 to 3. • The port argument is the voice interface card location. Valid entries are 0 to 3. • The ds0-group-number argument indicates the defined DS0 group number. Each defined DS0 group number is represented on a separate voice port. This allows you to define individual DS0s on the digital T1/E1 card. Command or Action Purpose 15 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 13 pri-group timeslots timeslot-range [nfas_d | service][voice-dsp] Example: Router(config-controller)# pri-group timeslots 1-5 Specifies that the controller should be set up as ISDN PRI interface. • For T1, – timeslots range from 1 to 24 – 23rd channel is the D channel • For E1, – timeslots range from 1 to 31 – 15th channel is the D channel Note Current “Service” is only for voice mgcp. So, when “Service” is selected, there is no “voice-dsp” required or needed. Note NIM-xCE1T1-PRI—The option keyword voice-dsp is only available to the NIM-xCE1T1-PRI (x could be 1, 2, or 8) on the ISR 4000 series. Default is without the keyword voice-dsp. The pri-group command on NIM-xCE1T1-PRI can be used for both data and voice. When you use the pri-group command for data, then the voice-dsp keyword is not required. When you use the pri-group command for voice, then the voice-dsp keyword is required. Note NIM-xMFT-T1/E1—Since the pri-group command on the NIM-xMFT-T1/E1 is only used for voice, the keyword voice-dsp is not needed. • If a controller is configured as PRI, individual channel groups cannot be configured on that controller. • The controller command must be entered before this command can be used. Step 14 end Example: Router(config-voiceport)# end Returns to privileged EXEC mode.

The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multipoint sessions. For more information about H.323, see the Cisco IOS H.323 Configuration Guide. For router configuration information, see the “Configuring H.323 Gateways” chapter of Cisco IOS H.323 Configuration Guide. Session Initiation Protocol Session Initiation Protocol (SIP) is a peer-to-peer, multimedia signaling protocol developed by the IETF (IETF RFC 3261). Session Initiation Protocol is ASCII-based. It resembles HTTP, and it reuses existing IP protocols (such as DNS and SDP) to provide media setup and teardown. For more information, see the Cisco IOS SIP Configuration Guide. For router configuration information under SIP, see the ““Basic SIP Configuration” chapter of the Cisco IOS SIP Configuration Guide. Voice gateways provide voice security through SIP enhancements within the Cisco IOS Firewall. SIP inspect functionality (SIP packet inspection and detection of pin-hole openings) is provided, as well as protocol conformance and application security. The user is given more granular control on the policies and security checks applied to SIP traffic, and the capability to filter unwanted messages.

DSP-farm Profiles A DSP-farm is the collection of available DSP resources. DSP-farm profiles are created to allocate DSP-farm resources. A DSP-farm profile allows you to group DSP resources based on the service type. Under a DSP farm profile, you select the service type (conference, transcode, or Media Termination Point [MTP]), associate an application, and specify service-specific parameters such as codecs and maximum number of sessions. Applications associated with the profile, such as SCCP, can use the resources allocated under the profile. You can configure multiple profiles for the same service, each of which can register with one Cisco Unified Communications Manager group. The profile ID and service type uniquely identify a profile, allowing the profile to uniquely map to a Cisco Unified Communications Manager group that contains a single pool of Cisco Unified Communications Manager servers. Conferencing Voice conferencing involves adding several parties to a phone conversation. In a traditional circuit-switched voice network, all voice traffic passes through a central device such as a PBX. Conference services are provided within this central device. In contrast, IP phones normally send voice signals directly between phones, without the need to go through a central device. Conference services, however, require a network-based conference bridge. In an IP telephony network using Cisco Unified Communications Manager, the Conferencing and Transcoding for Voice Gateway Routers feature provides the conference-bridging service. Cisco Unified Communications Manager uses a DSP farm to mix voice streams from multiple participants into a single conference-call stream. The mixed stream is played to all conference attendees, minus the voice of the receiving attendee. The Ad Hoc and Meet-Me conferencing features are supported (a conference can be either of these types): • Ad Hoc—The person controlling the conference presses the telephone conference button and adds callers one by one. • Meet-Me—Participants call in to a central number and are joined in a single conference. Participants whose end devices use different codec types are joined in a single conference; no additional transcoding resource is needed. 23 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Configuring a DSP-farm Profile Perform this procedure to define a DSP-farm.

Step 4 dsp services dspfarm Example: Router(config-voicecard)# dsp services dspfarm Enables DSP-farm services for the voice card. Step 5 exit Example: Router(config-voicecard)# exit Exits voice-card configuration mode. 24 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Step 6 dspfarm profile profile-identifier {conference | mtp | transcode [universal]} Example: Router(config)# dspfarm profile 20 conference Enters DSP-farm profile configuration mode to define a profile for DSP-farm services. Note The profile-identifier and service type uniquely identify a profile. If the service type and profile-identifier pair is not unique, you are prompted to choose a different profile-identifier. Step 7 description text Example: Router(config-dspfarm-profile)# description art_dept (Optional) Includes a specific description about the Cisco DSP-farm profile. Step 8 codec codec-type Example: Router(config-dspfarm-profile)# codec ilbc Specifies the codecs supported by a DSP farm profile. • Repeat this step for each codec supported by the profile. Note Hardware MTPs support only G.711 a-law and G.711 u-law. If you configure a profile as a hardware MTP, and you want to change the codec to something other than G.711, you must first remove the hardware MTP by using the no maximum sessions hardware command. Note Only one codec is supported for each MTP profile. To support multiple codecs, you must define a separate MTP profile for each codec. Step 9 maximum sessions number or maximum sessions {hardware | software} number Example: Router(config-dspfarm-profile)# maximum sessions 4 Specifies the maximum number of sessions that are supported by the profile. • number—Range is determined by the available registered DSP resources. Default is 0. Note The hardware and software keywords apply only to MTP profiles. Step 10 associate application sccp Example: Router(config-dspfarm-profile)# associate application sccp Associates the SCCP protocol to the DSP-farm profile. Step 11 no shutdown Example: Router(config-dspfarm-profile)# no shutdown Enables the profile, allocates DSP-farm resources, and associates the application. Step 12 end Example: Router(config-dspfarm-profile)# end Exits DSP-farm profile configuration mode. Command or Action Purpose 25 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module Network Synchronization for the Cisco ISR 4000 Series For Cisco 4000 Series ISRs, the clocking mechanism on T1/E1 is changed. You must configure the network-clock synchronization automatic global command which is disabled by default and this will ensure other network-clock commands take effects. For further information, see http://www.cisco.com/c/en/us/td/docs/routers/access/4400/feature/guide/isr4400netclock.html. The network-clock-participate command in Cisco 2900/3900 ISR is replaced by network-clock synchronization participate command in Cisco 4000 series platforms. The network-clock-select command in ISR 2900/3900 is replaced by network-clock input-source command in Cisco 4000 series platforms. In Cisco 4000 series ISR, when you do not sync up the clock across different modules, you don not have to participate the clock to the backplane with the network-clock CLI for voice configuration. To disable clock participate, enter no network-clock synchronization participate slot / subslot. There is no default clock source on Cisco 4000 series ISR backplane and you must have to configure the network-clock input-source command with the network-clock synchronization participate command. In Cisco 4000 Series ISRs, the NIM module can be its own clock domain if no network-clock synchronization participate command is configured for that NIM module. On a single NIM, all the T1/E1 lines with voice ports should share the same clock source. You can recover the clock source from line: clock source line [primary|secondary] or from module internal clock: clock source network. Both data and voice can run on the same NIM module. Cisco Unified Border Element Cisco Unified Border Element (Cisco UBE) is a session border controller that provides the necessary services for interconnecting independent Unified Communications networks securely, flexibly, and reliably. Media packets can flow either through the gateway (thus hiding the networks from each other) or around the border element, if so configured. The Cisco UBE is typically used to connect enterprise networks to service provider SIP trunks, or to interconnect different nodes in an enterprise network where protocol or feature incompatibilities exist, or where extra secure demarcation between segments of the network is needed. The Cisco Unified Border Element provides the following network-to-network interconnect capabilities: • Session Management: Real-time session setup and tear-down services, call admission control, ensuring QoS, routing of calls if an error occurs, statistics, and billing. • Interworking: H.323 and SIP protocol conversion; SIP normalization; DTMF conversion, transcoding, codec filtering. • Local Transcoder Interface (LTI) for audio transcoding. For more information, see the Cisco Unified Border Element Configuration Guide at Cisco.com. Cisco Unified Survivable Remote Site Telephony Cisco Unified Survivable Remote Site Telephony (SRST) enables Cisco routers to provide call-handling support for Cisco IP phones when they lose connection to Cisco Unified Communications Manager (CUCM) installations or when the WAN connection is down. In a centralized deployment, under normal conditions, Cisco IP phones are controlled by the Cisco Unified Communications Manager located at a 26 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Configuring the Cisco Network Interface Module central site like the headquarters of an enterprise. When the connection to CUCM breaks, for example as a result of a failure in the network, Unified SRST automatically detects the failure and auto-configures the router to provide backup call processing functionality. During a WAN failure, the router allows all the phones to re-register to the remote site router in SRST mode, allowing all inbound and outbound dialing to be routed off to the PSTN (on a backup FXO, BRI or PRI connection). Unified SRST provides redundancy for both Cisco IP phones and analog phones to ensure that the telephone system remains operational during network failures. Both Skinny Client Control Protocol (SCCP) and Session Initiation Protocol (SIP) based Cisco IP phones are supported with Unified SRST. When the WAN link or connection to the Cisco Unified Communications Manager is restored, call handling automatically reverts back to the Cisco Unified Communications Manager without the need for any human intervention. For general Unified SRST information, see the Cisco Unified SRST System Administrator Guide. • For information on how the H.323 and Media Gateway Control Protocol (MGCP) call control protocols relate to SRST, see the Cisco Unified SRST System Administrator Guide: – For H.323, see H.323 Gateways and SRST on Cisco.com. – For MGCP, see MGCP Gateways and SRST on Cisco.com. • Configurations of major SRST features are provided in the following chapters of the Cisco Unified SRST System Administrator Guide: – “Setting Up the Network” – “Setting Up Cisco Unified IP Phones” – “Setting Up Call Handling” – “Configuring Additional Call Features” – “Setting Up Secure SRST” – “Integrating Voice Mail with Cisco Unified SRST” For SIP-specific SRST information, see the Cisco Unified SCCP and SIP SRST System Administrator Guide. To configure SIP SRST features, see the “Cisco Unified SIP SRST 4.1” chapter. IVR and TCL IVR is a term that is used to describe systems that collect user input in response to recorded messages over telephone lines. User input can take the form of spoken words or, more commonly, dual tone multifrequency (DTMF) signaling. For example, when a user makes a call with a debit card, an IVR application is used to prompt the caller to enter a specific type of information, such as a PIN. After playing the voice prompt, the IVR application collects the predetermined number of touch tones (digit collection), forwards the collected digits to a server for storage and retrieval, and then places the call to the destination phone or system. Call records can be kept and a variety of accounting functions can be performed. The IVR application (or script) is a voice application designed to handle calls on a voice gateway, which is the router equipped with voice features and capabilities. The prompts used in an IVR script can be either static or dynamic: • Static prompts are audio files referenced by a static URL. The name of the audio file and its location are specified in the Tool Command Language (TCL) script. 27 Configuring the Cisco Fourth-Generation T1/E1 Voice and WAN Network Interface Module OL-28913-01 Troubleshooting • Dynamic prompts are formed by the underlying system assembling smaller audio prompts and playing them out in sequence. The script uses an API command with a notation form to instruct the system what to play. The underlying system then assembles a sequence of URLs, based on the language selected and audio file locations configured, and plays them in sequence. This provides simple Text-to-Speech (TTS) operations. For example, dynamic prompts are used to inform the caller of how much time is left in their debit ccount, such as: “You have 15 minutes and 32 seconds of call time left in your account.” Note The above prompt is created using eight individual prompt files: youhave.au, 15.au, minutes.au, and.au, 30.au, 2.au, seconds.au, and leftinyouraccount.au. These audio files are assembled dynamically by the underlying system and played as a prompt based on the selected language and prompt file locations. TCL is an interpreted scripting language. Because TCL is an interpreted language, scripts written in TCL do not have to be compiled before they are executed. TCL provides a fundamental command set, which allows for standard functions such as flow control (if, then, else) and variable management. By design, this command set can be expanded by adding extensions to the language to perform specific operations. Cisco created a set of extensions, called TCL IVR commands, that allows users to create IVR scripts using TCL. Unlike other TCL scripts, which are invoked from a shell, TCL IVR scripts are invoked when a call comes into the gateway. For more information on TCL IVR, see the Tcl IVR APi Version 2.0 Programming Guide.

Le développement économique mais aussi technologique conduit les entreprises à apporter une attention plus grande à la formation du personnel. . L'émergence des Nouvelles Technologies Informatiques (NTI) peut, potentiellement, "révolutionner" l'acte pédagogique. Les systèmes de formation doivent faire face à des obligations sans cesse croissantes quant au nombre des stagiaires, à la qualité des remises à niveau, c'est à dire à l'adaptation rapide et efficace des formés aux nouveaux postes de travail. Aussi leur faut-il mettre en pratique des modes d'enseignement de plus en plus performants. Face à ce redéploiement de la formation, les entreprises sont conduites à rechercher des solutions appropriées pour réaliser, dans les meilleures conditions, les buts pédagogiques visés. Autrement dit, il s'agit d'optimiser les ressources affectées à la formation pour atteindre les objectifs prévus. Or, dans ce contexte, de nouveaux outils didactiques se trouvent à la disposition des systèmes de formation : les NTI, et, plus particulièrement, l'Enseignement Assisté par Ordinateur (EAO). L'Association pour la Recherche et le Développement de l'Enseignement Multimedia Informatisé (ARDEMI) a fédéré différentes initiatives pour la création et l'utilisation de ces NTI (pour une présentation plus complète de l'ARDEMI, se reporter à l'annexe 1). Dans toute réflexion liée a leur intégration possible dans l'acte de formation, l'intervention de l'économiste trouve toute justification. En 3 effet, sa réflexion- va porter sur l'optimisation des ressources employées. La mise en oeuvre des nouveaux outils va-t-elle permettre d'améliorer la productivité du système de formation ? Les NT! sont-elles plus efficaces pour atteindre tel objectif spécifique d'enseignement ? Il s'agit bien de raisonner à l'intérieur du système de formation et de voir en quoi l'intégration de nouveaux auxiliaires va permettre de mieux réaliser les objectifs prévus (par rapport à la formation traditionnelle). Le système scolaire initial a connu, ces dernières années, une certaine pénétration de ces nouveaux moyens pédagogiques. Globalement, leur utilisation demeure, pour des raisons très diverses, encore relativement timide. Par contre, on peut penser que pour des motifs de contraintes organisationnelles moins fortes, leur multiplication se montrera plus rapide dans la formation continue. Cependant, toute mise en- oeuvre très large de ces moyens passe par un impératif majeur : l'amélioration, grâce à ces nouveaux auxiliaires, du rapport coüt-efficacité. 1) Le rapport coût-efficacité Choisir entre deux formes d'enseignement signifie évaluer pour chacune, la réalisation des objectifs prévus. Il s'agit alors de voir dans quelle mesure tel outil pédagogique permet une meilleure atteinte des intentions didactiques. L'objet de l'analyse développée relève de l'évaluation de l'efficacité interne, c'est-à-dire de l'examen d'une éventuelle amélioration du rapport coüt-efficacité. Dans l'hypothèse d'une évolution défavorable, il serait alors utile de s'interroger sur la nécessité d'introduire de nouveaux outils. 4 L'ensemble de la-question repose, en fait, sur deux variables: la baisse des coûts, l'amélioration de l'efficacité. *La baisse des co'O.ts : l'introduction de matériels nouveaux supplémentaires peut laisser sous-entendre des surc011ts. Les défenseurs des nouvelles technologies informatiques annoncent, par contre, des possibilités .certaines de baisse de coûts. La question est importante. Il s'agit essentiellement de voir dans quelle mesure cette pénétration de nouveaux outils permettra une baisse des "inputS11 • L'un des points forts relève du coût de l'enseignant; va-t-il diminuer du fait de la substitution homme/machine ? * L'amélioration de 1' efficacité aux côtés -d'une . baisse possible des coûts, l'intégration de ce noUvel outil doit aussi améliorer la formation. Un grand nombre d'effets quantitatifs et qualitatifs sont envisageables : il convient de les mettre en lumière lors des évaluations de la mise en oeuvre de l'EAO. Quelle évaluation peut-on faire du rapport coût-efficacité ? En premier lieu, l'approche menée se situant dans le cadre de l'efficacité interne, aucune mesure monétaire de cette dernière ne se réalise. L'approche générale relève de l'analyse des relations entre les coûts et les effets des outils introduits. Les critères d'appréciation de l' 11 output 11 prennent en compte à la fois les. répercussions sur les formés, sur le formateur et le système de formation. En effet, tout acte de formation fait intervenir ces trois pôles et c'est essentiellement par rapport à eux que 1' on peut envisager des répercussions sur les coûts et sur 1' efficacité : ce sont eux qui constituent 1' origine des dépenses face à tout acte d'enseignement, et c'est sur eux que 1' outil engagé peut manifester des effets. Ainsi, toute possibilité de baisse des 5 coûts et d'amélioration de 1 'efficacité apparaîtra sur 1 'un ou plusieurs de ces pôles, puisque l'introduction d'un nouvel outil peut engendrer d'autres "inputs 11 (coût du formateur, limitation de la durée du stage ... ). L'approche en termes d'efficacité quant à elle repose donc sur l'analyse des effets quantitatifs et qualitatifs de l'EAO. Il s'agira, dès lors, de mettre en rapport les coûts et les effets obtenus puis d'examiner les conditions d'une situation optimale. La décision d'introduire le nouvel outil dans la formation a pour base la réponse à la question suivante : les effets obtenus par rapport aux coîlts, grâce aux moyens mis en oeuvre, sont-ils meilleurs que ceux apportés par la formation traditionnelle ? A ce niveau, une remarque s'impose. L'étude du rapport coût-efficacité sous-entend la comparaison formation traditionnelle et EAO. Est-ce réellement une alternative ? En toute logique, un responsable chargé d'organiser une formation peut s'interroger : la fera-t-il assurer par cours traditionnel ou par EAO ? La question ne se pose, en ·fait, pas toujours en ces termes. Dans certains cas, seul tel mode d'enseignement, ou tel outil permet une bonne réalisation de l'objectif pédagogique. Il est certain que l'on ne transmet pas exactement le même message par des instruments différents. C'est alors qu'il s'agit de choisir la meilleure façon de réaliser les intentions didactiques prévues. Tenant compte de cette limite de l'analyse coût-efficacité, il faut voir dans quelle mesure l'EAO apporte des effets que l'on n'obtenait pas (ou plus difficilement) en traditionnel. .. autre façon de poser la question coût-efficacité. Il est clair que la démarche s'inscrit dans un cadre très large ne se limitant pas aux aspects quantitatifs, mais intégrant aussi l'apport / 6 qualitatif. Il serait effectivement bien tentant (mais pas si facile) d'apposer deux nombres aux numérateur et dénominateur du rapport coût-efficacité. Il deviendrait alOrs aisé de tirer des lois de variations mathématiques selon la propre évolution de chacun. La réalité demeure plus complexe. Toute tentative de réduction de la notion d'efficacité aux seuls effets quantifiables doit être écartée, l'approche qualitative revêtant une dimension tout aussi forte. Il est évident que la non prise en co.mpte de ce deuxième axe laisse échapper des dimensions importantes du problème. Malgré cette impossibilité de modélisation mathématique, une réflexion sur une évolution favorable du rapport coüt-efficacité reste possible. En clair, on peut distinguer trois cas dans lesquels il y a, sans aucun doute, amélioration du rapport coût-efficacité. Coûts identiques & meilleure efficacité : les effets de la mise en oeuvre du nouvel outil se manifestent quantitativement et/ou qualitativement. Coûts plus bas & efficacité identique : il s'agit avant tout de mettre en évidence la baisse des coûts. L'efficacité identique s'admet comme une atteinte identique des objectifs pédagogiques pour une même durée de formation. Coûts plus bas & meilleure efficacité : cette situation correspond à la solution optimale. Les deux facteurs évoluent favorablement. Par contre, dans les trois cas inverses, apparaît une détérioration du rapport coût-efficacité : coûts identiques & moindre efficacité, coûts plus élevés & efficacité identique, coûts plus bas & moindre efficacité. 7 Face à ces six cas présentant une évolution claire du rapport (favorable ou défavorable), il faut distinguer deux autres situations plus difficiles à analyser : Coûts plus élevés & meilleure efficacité : il est, dans ce contexte, difficile de se prononcer, on est dans un cas douteux. La question afférente à cette situation repose sur un point principal : les effets produits justifient-ils réellement la hausse du coût ? Toute réponse relève d'un jugement de valeurs, exprimé par le décideur qui détermine, par rapport à d'autres éléments extérieurs, sa stratégie. Coûts plus bos & moindre efficacité : bien que ce cas apparaisse, en toute logique, possible, il semble difficilement envisageable qu'un responsable de formation choisisse un tel cas de figure. L'impossible quantification absolue de l'efficacité condamne le rapport coût-efficacité à l'inexistence chiffrée. Malgré cela, il est primordial d'évaluer l'effteacité des formes d'enseignement. 2) Structure et problématique générale des coOts de l'enseignement assisté par ordinateur Un nouvel outil pénètre les systèmes de formation., .. Qu'il remplace ou complète la panoplie des auxiliaires pédagogiques utilisés jusqu'à ce jour, il laisse apparaître des éléments nouveaux -intervenant désormais dans le calcul du coût d'une formation. 8 2.1 Classification principale des coûts : Cinq dimensions paraissant les plus utiles face à l'intégration de l'EAO dans la formation sont retenues : technique : cette approche distingue les coûts relatifs aux différents stades d'élaboration et de mise en oeuvre de l'EAO : conception, informatisation, transmission, réception. financière : cette classification repose sur la distinction entre les payeurs. Elle différencie l'origine des financements des coüts engendrés par l'introduction du nouvel outil. On sépare alors les coûts à la charge de l'organisme assurant la mise en oeuvre de la nouvelle technique, ceux couverts par les usagers, puis les dépenses assumées par la collectivité. comptable : elle sépare les investissements en capital et les dépenses de fonctionnement. Cette dichotomie s'avère intéressante puisqu'elle montre les dépenses initiales nécessaires au développement de 1' outil puis celles qui permettent son fonctionnement. coats estimatifs!coats estimés!coats réels : l'évaluation des coûts peut s'opérer avant la mise en oeuvre de l'outil considéré, ce qui conduit au calcul de coüts estimatifs (ex ante). Une fois l'installation réalisée et utilisée, il est alors possible de mesurer les coüts réels d'investissement et de fonctionnement. Cependant, Je calcul.des coüts réels de fonctionnement de l'EAO semble bien souvent difficile à établir. On se trouve alors dans l'obligation de calculer des coûts estimés (à postériori) reposant sur des hypothèses et des ratios d'approximation. 9 économique :l'économiste se préoccupe avant tout de l'optimisation de la production. L'étude statique des coûts ne revêt pas, pour lui, une importance première. Il s'intéresse surtout à la structure des coûts et à leur variation en fonction du niveau de la production. C'est ainsi que la distinction entre coût fixe et coût variable prend toute son ampleur. Les calculs par unité produite (coüt unitaire ou moyen) sont privilégiés et l'intérêt majeur relève, en fait, de l'étude de l'évolution de ce coût moyen par rapport aux quantités produites. Il s'agit alors de définir ce que 1' on considère comme unité produite. Si l'on veut raisonner en termes d'évolution des coûts, en comparaison avec 1' enseignement traditiortnel, il est nécessaire de distinguer les coûts fixes et variables. Le coût variable représente la partie du coût total qui évolue avec le niveau de la production. Il est donc fonction directe des quantités réalisées. Son évolution n'est pas forcément proportionnelle à la production, elle va, certes, dans le même sens. A l'inverse, le coût fixe demeure inchangé, quel que soit le niveau de production. Il est intégré une fois pour toutes. La distribution des coüts fixes et variables à l'intérieur du coût total détermine l'évolution des coüts en fonction du niveau de la production. Plus les coûts variables ont un poids important, plus le coût total dépend de la production. Il augmente alors avec l'accroissement des quantités réalisées. Par contre, une forte part de coüts fixes induit une évolution différente. Par définition, ces coûts restent identiques quelle que soit la production. Plus le nombre d'objets créés s'accroit, plus les cot\ts fixes sont partagés. Le coût total reste quasi identique. Cela a pour conséquence une baisse du coüt moyen avec l'accroissement de la production. Lorsque les coûts fixes ont un poids significatif, le cotit moyen (ou unitaire) baisse avec la taille croissante de la population. Lorsque le coüt moyen diminue avec l'augmentation 10 de la production (on produit chaque unité moins cher) des économies d'échelle se réalisent. La productivité des facteurs s'améliore et de ce fait il y a baisse du coût unitaire. Dans le champ de la formation continue, le but essentiel étant la mise à niveau des formés, 1 'unité de base généralement utilisée est le stagiaire. On obtient donc un coût par stagiaire. Il faut souligner, en formation adulte, l'importance de la durée du stage (en nombre d'heures). Un calcul de coüt horaire en fonction de la durée du stage, apparaît, par conséquent, fort utile. La prise en compte de ces deux dimensions conduit à l'établissement d'un indice synthétique : le coût horaire par -stagiaire. Pour la comparaison entre deux méthodes pédagogiques, il peut aussi être intéressant de réfléchir en termes de coût du stage pour un effectif donné de personnes à former. Toute comparaison des coftts entre formation traditionnelle et avec EAO procède en premier lieu de l'examen, pour chaque système de la part coûts fixes/coûts variables. L'enseignement traditionnel qui repose essentiellement sur la relation formateur/élèves, laisse une part importante aux coûts variables. Qu'en est-il de la formation avec EAO? Avant de répondre à cette question et d'apporter des éléments de réflexion pour une comparaison valable, une analyse de la structure des coüts de l'EAO s'avère utile. L'analyse se doit d'englober à la fois les coûts directs liés spécifiquement à la formation reçue et ceux, indirects, évoluant en parallèle avec le cursus. Les premiers prennent en compte toute la dimension d'enseignement (matériel - fonctionnement- formateur). Les seconds souvent non intégrés appartiennent au domaine non pédagogique (salaire des formés- frais de déplacement). 11 Les coûts directs sont relatifs au coüt du matériel et au coüt de fonctionnement. * Coût du matériel Coût des micro-ordinateurs : Il reste primordial de cotlllaître 1' affectation des machines : enseignement uniquement ou poste de travail et formation. A côté des problèmes liés à l'évaluation du nombre annuel d'heures d'utilisation réelle des micro-ordinateurs, intervient le problème de l'amortissement de ces matériels. En effet, les micro-ordinateurs étant utilisés sur des périodes plus ou moins longues, une réflexion s'impose à cet égard. Ces matériels qui relèvent des technologies avancées deviennent, de par l'évolution technique, très vite obsolètes. C'est ainsi que certaines institutions choisissent une durée d'amortissement de deux années. Cela paraît tout de même très court puisque le micro-ordinateur, à l'issue de cette période, conserve tout de même un certain potentiel d'utilisation. L'administration retient pour les matériels de bureau un taux d'amortissement linéaire de dix à vingt pour cent. Cela conduit à envisager une durée de cinq à dix années. Cependant, un texte du 29 Février !988 signifie les possibilités suivantes : "L'entreprise doit être en mesure de justifier les circonstances particulières qui conduisent à retenir une durée d'amortissement inférieure aux usages professionnels qui traduisent la durée normale d'utilisation des biens. Cela étant, l'administration s'abstient de remettre en cause les durées d'amortissement retenues par les entreprises en raison de ces circonstances particulières, lorsqu'elles ne s'écartent pas de plus de 20% des usages professionnels". (Inst. 29 Février !988, 4 DI- 88 LEFEBVRE BIC Memento Fiscal). 12 Coût des autres matériels annexes : aménagement d'une salle spécifique et amortissement du coût d'installation de l'ensemble. Co(lt du/des didacticie/(s) : concernant la mise à disponibilité du/des didacticiel(s) considéré(s), deux cas s'envisagent. Le premier relève de l'achat sur le marché du logiciel désiré au prix de celui-ci, le second procède de la production de l'outil pédagogique lui-même. De même que pour les micro-ordinateurs, il faut considérer une période d'amortissement des didacticiels. Le choix de la durée varie là encore énormément. L'administration fiscale signifie que le taux se détermine "compte tenu de l'évolution prévisible des concepts et techniques 11 • Elle autorise même un amortissement, pour ce type de matériel, d'une année. Au-delà de cette possibilité fiscale, l'adoption d'une période change surtout avec les connaissances diffusées. * Coilt de fonctionnement : Coat de maintenance des machines : contrats d'entretiens ... Coat des supports : documents livrés aux stagiaires, papier pour l'imprimante. Charges diverses de fonctionnement : électricité, assurances, locaux, fournitures pédagogiques, personnel permanent ..... Coat en personnel : tout d'abord, les coûts en personnel représentent les coûts salariaux (salaire + charges patronales). Lorsque sa présence est maintenue, il s'agit d'évaluer le nombre d'heures d'intervention du formateur. 13 Dans certaines institutions, il apparaît intéressant d'examiner l'évolution de la part de face à face pédagogique et de préparation de cours. Cela se montre important pour l'institution elle-même : dans l'hypothèse d'une baisse de temps de préparation, un nombre supérieur d'élèves par formateur peut alors être pris en compte. En effet, dans certains cas, la diminution des temps de préparation, peut induire une baisse du coût global des formateurs ...... chacun assurant plus de cours. D'un autre côté, pour les centres ressources, il faut retenir le coût de 11 l'homme ressource 11 chargé d'apporter les compléments d'informations. Par ailleurs, certaines entreprises ou institutions de formation procèdent parfois à la création d'un ou plusieurs postes/hommes chargés de réfléchir sur l'EAO, son intégration et son déploiement. Au-delà de cette première tâche, cette (ces personnes) examine(nt) les problèmes spécifiques de formation au sein de l'entreprise. Elle(s) envisage(nt) par rapport à la situation réelle, une mise en oeuvre de l'outil tout en tenant compte des dimensions économiques, sociales, humaines. De plus, elle(s) représente( nt) souvent l'interlocuteur EAO. Les coûts engendrés par ce nouveau service sont essentiellement salariaux. Il est d'ailleurs difficile d'intégrer pour une session précise la part de coûts relative à ce domaine ; la mise au point d'un ratio adéquat n'apparaît pas toujours évidente. Les coûts indirects concernent : Salaires des fonnés : il est fondamental pour la comparaison des coûts d'une formation traditionnelle avec un cursus intégrant l'EAO, 14 d'inclure les salaires des formés. Quoi qu'il en soit, toute modification de la durée de stage intervient dans l'établissement de ces coûts. Frais de déplacement : ils recouvrent ceux relatifs aux formés et/ou au formateur et correspondent aux déplacements journaliers remboursés au prix/kilomètre ou aux dépenses hôtelières. Quelle différence existe-t-il entre structure et évolution des coûts en système traditionnel et avec EAO ? Généralement peu de capital s'intègre dans 1' acte d'enseignement traditionnel, exceptés les élénients minima nécessaires tels bâtiments, mobilier ... Les co'O.ts fixes apparaissent donc limités. A l'inverse, les dépenses en travail qualifié (rémunération des formateurs) sont importantes. Elles varient de façon discontinue avec le nombre d'élèves formés et induisent pàr conséquent, une augmentation du coût total avec la taille de l'auditoire. Cela pose d'ailleurs à certaines entreprises des problèmes importants dès lors qu'elles se trouvent dans l'obligation de former un nombre très large de personnes sur une période limitée. Il leur faut, pour satisfaire les exigences de formation, augmenter le nombre d'enseignants de façon significative ; les coûts deviennent très vite considérables. L'intégration de l'EAO nécessite, bien évidemment, dans un premier temps, des dépenses supplémentaires en capital ; la dotation principale correspond essentiellement à 1' acquisition de microordinateurs et de didacticiels. Cela n'entraîne pas obligatoirement une hausse des coûts puisque la répartition entre coûts fixes et coûts variables se modifie. Les premières études retiennent dès lors l'hypothèse d'une hausse des coûts fixes. Cette perspective prend en compte la mise à disposition d'une quantité figée de matériel pour une période donnée, le parc machines n'évoluant pas parallèlement avec 15 la croissance de la population à former:. Le maximum de stagiaires travaille sur les micro-ordinateurs présents. Le coût moyen relatif au matériel décroît avec l'augmentation de la taille de l'auditoire .... pour peut-être devenir dérisoire lors d'une pratique intensive de l'EAO. Les économies d'échelle sont alors importantes. En fait, la question paraît moins facile. Une mise en oeuvre étendue de l'EAO laisse envisager que la seule installation d'une salle unique contenant X micro-ordinateurs semble aujourd'hui moins systématiquement retenue. Même si les débuts de recours à l'EAO passent par l'installation d'une classe (ou l'achat de quelques micro-ordinateurs), la nécessité de former de plus en plus de personnes avec un appel croissant à l'EAO change la nature du problème. Il s'agit moins d'un 11 bloc" opérationnel mis à la disposition d'un certain nombre de formés, mais de plusieurs mis en place en fonction de la croissance de la demande. De fait, l'évolution qui se dessine laisse plutôt montrer une variation discontinue des coûts en matériel informatique en fonction de la population à former. Pour les didacticiels, la loi d'évolution dépend avant tout de caractéristiques techniques. Plusieurs cas sont à prendre en considération : . Pour une même formation, il est quelquefois obligatoire d'acheter autant de didacticiels que de postes/élèves. Les coûts varient alors en fonction du nombre de micro-ordinateurs installés. La loi d'évolution du coût didacticiel en fonction du nombre d'élèves devient identique à celle des micro-ordinateurs . . Pour d'autres situations, telle contexte ARDEMI (Association pour la Recherche et le Développement de l'Enseignement Multimedia Informatisé), les adhérents possédent un didacticiel qu'ils installent sur 16 chacun des postes. Exceptée la nécessité d'avoir un interpréteur par micro, le même didacticiel se "multiplie" sur plusieurs postes. Dans ce cas, le coüt didacticiel est fixe. Il en va de même pour une structure en réseau avec une tête diffusant le didacticiel à chacun des postes annexes . . Bien que non encore développé de manière large, le recours à I'EAO avec transmission électromagnétique (ligne téléphonique, transpac ..... ) devrait devenir important dans les années futures. La loi d'évolution des coftts est alors souvent corrélative à la durée de la plage de travail. Au-delà des coûts spécifiques liés au matériel utilisé, l'introduction de 1 'EAO amène des coûts supplémentaires bien souvent minimisés. Il est vrai, qu'en regard des dépenses en matériel, ils apparaissent peu élevés. De plus, étant pour la plupart fixes, leur poidS ramené au coût unitaire se montre négligeable. Par ailleurs, les co1lts de fonctionnement général (électricité ... ) varient peu avec la taille de l'auditoire. Pour les disquettes, cela dépend du mode de diffusion de l'EAO. S'il est nécessaire d'avoir un jeu de disquettes par poste, les coûts varient avec le nombre de micro-ordinateurs. Par contre, dans le cas d'un réseau ou d'une implantation sur disque dur, le co1lt des disquettes est fixe (une seule série se montre suffisante). En ce qui concerne le papier, les didacticiels ont dans l'ensemble peu de recours à 1 'imprimante. Si cela se produit, il faut considérer un coüt variable proportionnel au nombre de stagiaires. Les coûts de maintenance des machines (contrat d'entretien lorsqu'il existe, réparations diverses .... ) varient en fonction du parc de machines. Ce dernier pouvant, comme nous l'avons vu, osciller avec la taille de la population à former, ces coûts. augmentent indirectement avec elle. 17 Excepté le cas de l'EAO pratiqué sur le poste de travail, il devient fréquent de regrouper les micro-ordinateurs dans une salle particulière. Or, le développement de l'EAO devenant plus fort, le nombre de salles ressources s'accroit. Ces dernières nécessitent très souvent des protections particulières : grille, alarme, serrure ..... Ce collt d'aménagement de locaux apparalt à peu près fixe sachant qu'il varie lors d'une augmentation significative du nombre d'ordinateurs. Le collt des personnes chargées du suivi de l'EAO et de son développement est essentiellement salarial. Il varie avec l'évolution des salaires mais ne dépend en aucun cas du nombre de formés. Par ailleurs, la mise à disposition de l'EAO en dehors des heures de service entraîne inévitablement des coûts supplémentaires : homme ressource, surveillance, charges de fonctionnement. Par contre, 1 'utilisation encore plus forte de micro-ordinateurs et de didacticiels contribue à l'accroissement du nombre de formés et donc à une baisse du coüt des matériels par stagiaire : dans ce cas, la répartition de la charge sur un plus grand effectif diminue le coüt du matériel par personne. Des économies d'échelle se réalisent alors. 2.2 Effets de l'introduction de l'EAO par rapport aux collts d'une formation traditionnelle : Ainsi que nous venons de le voir, des coûts supplémentaires dus à l'utilisation de l'EAO apparaissent. La question fondamentale repose alors sur l'impact de ces coüts supplementaires par rapport au collt de formation traditionnelle. Malgré ces surcollts, ne peut-on pas envisager une baisse du coût unitaire, les lois d'évolution en fonction du nombre de formés étant différentes pour les deux formes d'enseignement ? Il est bon d'y réfléchir sachant que ces deux modes de formation ne représentent pas nécessairement une alternative. Un des 18 points clés de toute cette réflexion représente alors la question du formateur. Notre propos se doit maintenant d'envisager le problème du formateur. Dans un second temps, nous tenterons de recenser quelques facteurs susceptibles de faire baisser le coût de formation par rapport aux sessions traditionnelles. L'influence sur le coût du formateur : Etudier l'évolution des coûts d'une formation intégrant l'EAO impose de tenir compte de la typologie des formes d'utilisations de ce nouvel outil. Au-delà de la prise en compte des coûts fixes ou variables liés à la technique (micro-ordinateur /didacticiel) intervient la question du formateur. Sa place induit ou non des coûts variables non négligeables. Plusieurs hypothèses sont à retenir, qui prennent en compte l'alternative que constitue la présence ou non du formateur. 1) Les connaissances sont diffusées à partir d'un 11 Stock11 fixe de micro-ordinateurs. Les coûts fixes sont importants; les coûts variables apparaissent faibles. Le coût de formation par stagiaire baissera avec l'augmentation de la taille de l'auditoire : les économies d'échelle sont fortes puisque la massification de la formation répartit plus largement les coûts fixes donc diminue le coût par unité produite. Dans le cas du maintien total du formateur (comme en Formation Traditionnelle), les coûts variables restent importants. Le surcoût par élève, dtî. au matériel utilisé, doit être minime surtout lors d'une utilisation intensive des machines (économies d'échelle). Lorsque le formateur intervient plus partiellement, il s'opère une économie au niveau de l'enseignant. Cette dernière est-elle compensée par le coût supplémentaire des matériels ? La réponse à une telle 19 question dépend de la formation envisagée et de la possibilité d'absence de l'instructeur. Celui-ci peut alors avoir une tâche de supervision, d'aide épisodique. Il n'est pas toujours présent dans la salle. On peut envisager qu'il suive parallèlement une seconde formation. Il circule alors d'une classe à l'autre et apporte des réponses aux diverses sollicitations des stagiaires. Une baisse du coût par stagiaire apparaît tout à fait envisageable. 2) Le nombre de micro-ordinateurs n'est plus figé et évolue de façon discontinue en fonction de l'importance de la population à former. Les coûts variables restent faibles; les coûts des matériels ne sont pas tout à fait fixes. L'augmentation de la taille de l'auditoire induit un recours plus important aux enseignants et aux machines. Le coût total croît avec la population. En cas de moindre intervention du formateur, l'évolution du coût total sera moins rapide. Tout dépend, comme nous l'avons montré ci-dessus, des possibilités d'absence de l'enseignant. Il semble plus difficile mais néanmoins possible d'envisager, pour ce cas, une baisse notoire du coût par stagiaire. Peut-on encore envisager des économies d'échelle ? La réponse semble positive tout en sachant bien que ces dernières demeurent moins fortes que dans le premier cas. La présence ou non du formateur manifeste des répercussions sur les coûts. A première vue, dans l'abstrait, des possibilités de substitution homme/machine existent; elles apparaissent plus ou moins importantes et dépendent de facteurs divers (qualité du didacticiel, niveau du public, autonomie dans l'apprentissage ... ). Dans le meilleur des cas, on peut envisager une forte substitution possible. Il convient de voir, dans la réalité, ce qui est envisageable à cet égard. Toute 20 possibilité d'obtenir des économies d'échelle apparalt avant tout liée au mode d'intégration de ce nouvel outil. Les possibilités de baisse de coats : Comme nous venons de le voir, des possibilités de baisse des coûts s'avèrent envisageables. Il apparaît donc intéressant d'examiner les conditions de leur minoration. a) Diminution du temps de formation Tout d'abord, une diminution du temps de formation doit contribuer à une réduction des coûts. Bien évidemment, il ne s'agit pas de limiter coûte que coûte la durée de session mais bien d'atteindre les mêmes objectifs pédagogiques sur une période plus courte. La limitation du temps de formation implique plusieurs incidences sur les coüts : . Temps d'intervention de l'enseignant moindre formateur moins élevé . coût du . Monopolisation plus réduite des matériels : cela permet à un plus grand nombre de stagiaires de travailler sur les machines . . Absence plus courte du poste de travail et réduction des salaires versés sans contrepartie productive . . Diminution dans certains cas des frais de déplacement. . Possibilité, comme nous avons déjà pu le mettre en évidence, de former un plus grand nombre de personnes. Cela peut permettre 21 dans certaines situations, de plus fortes économies d'échelle : stock fixe de micro-ordinateurs et de didacticiels (encore plus importantes si l'achat d'un seul logiciel permet une installation sur toutes les machines). b) Modification de l'activité du formateur Ainsi que nous avons déjà pu l'appréhender, la part d'intervention du formateur agit de façon non négligeable sur les coûts. L'enseignement traditionnel reposant essentiellement sur lui, sa disparition totale ou partielle induit nécessairement une baisse des coüts. L'absence partielle de 1 'instructeur lui permet d'assurer un travail de préparation de formations futures. Sur un quota d'heures identique, englobant temps de préparation et face à face pédagogique, le second peut alors devenir quantitativement plus élevé. Ceci autoriserait la prise en compte d'un nombre croissant d'élèves. Il est parfois envisagé qu'une moindre présence du formateur, au sein d'un cursus, rende possible un suivi simultané de plusieurs sessions parallèles. La baisse des coûts devient alors très forte. Cependant, une remarque s'impose. Ce type de pratique tout à fait réalisable modifie le rôle pédagogique de l'enseignant. Le formateur 11 glisse" alors vers ce qu'il est convenu d'appeler une action "d'homme ressource 11 • Enfin l'EAO apportant la base d'un cours, l'adaptation des nouveaux enseignants (approche générale du cours- contacts d'harmonisation avec les autres formateurs) devient plus rapide. Etant plus vite opérationnels, ils consacrent dès lors moins de temps à toute organisation préalable au démarrage dans l'établissement. Pour certaines institutions, ce point revêt une importance particulière. En effet, elles connaissent un turn-over important de leurs intervenants. 22 c) Autres facteurs L'utilisation de l'EAO comme support de cours, et par conséquent comme trame générale, évite l'achat de progressions pédagogiques vendues par des groupements spécialisés (certaines institutions achètent, pour assurer tel ou tel cours, une progression pédagogique livrant tout le cursus et la démarche à suivre pour atteindre l'objectif cognitif visé). Par ailleurs, dans le cas de centres d'enseignement individualisé, la pénétration de l'EAO contribue à réduire les frais de tirage de fiches de travail cartonnées. Une utilisation par un grand nombre de stagiaires nécessite des frais de duplication croissants. A défaut de résultats globaux concernant l'impact de l'EAO sur les coa.ts de formation, la présente réflexion met en lumière toutes les difficultés de leur estimation et de leur loi d'évolution. L'économiste doit-il pour cela renoncer à toute tentative d'approche exhaustive? La question ne se pose pas en ces termes. La très grande souplesse d'utilisation de ce nouvel outil impose une étude spécifique propre à chaque forme d'intégration. Tout d'abord, toute analyse économique doit prendre en compte la philosophie générale de pénétration de ce nouvel auxiliaire pédagogique : . Qu'attend-on de ce nouvel outil? . Est-il introduit comme substitut du formateur ou comme complément pour une amélioration de la formation ? . Va-t-il, dès lors, augmenter les coûts de formation ou peut-on en espérer une baisse ? 23 Certes, l'ensemble de cette approche s'opère à partir d'une base de comparaison : 1' enseignement traditionnel. Ces deux formes apparaissent-elles réellement substituables et source de confrbntation ? ·L'écueil profond sur lequel bute l'économiste provient en fait de la réponse plutilt négative à cette question. Ceci crée la difficulté. Dans certaines situations se réalise une substitution totale ; dans d'autres, elle est plus partielle. Enfin dans un troisième cadre, il faut parler de complémentarité. Malgré cela, le seul recours pour livrer une réflexion sur cette nouvelle technologie de formation s'appuie sur la base traditionnelle. Lorsque les critères de mise en oeuvre sont définis très précisément (annexe 1), une situation de comparaison apparaît possible. Cette dernière repose alors sur deux points forts : le nombre de· stagiaires visés, la durée de formation. Une loi d'évolution des ·coûts peut ainsi s'établir. La véritable comparaisori en termes financiers se réduit alors en une question forte : à partir de quel effectif ou de quel nombre d'heures/élèves parvient-on à un coût égal, puis inférieur à une formation traditionnelle ? Une approche de la rentabilité uniquement en termes de coûts apparaît quelque peu réductrice. Bien que cette dimension revête une importance particulière, toute réflexion sur l'acte d'enseignement a pour obligation d'évaluer l'apport auprès des élèves. Afin de poser réellement le problème, il convient, parallèlement, d'étudier les effets quantitatifs et qualitatifs sur la formation ciblée. Même si, de par leur nature, les éléments qualitatifs s'apprécient plus difficilement, ils demeurent, dans bien des cas, primordiaux. Là encore, se pose la véritable question : qu'est-ce que la rentabilité? Comment la définir ? Le caractère particulier de l'enseignement rend bien plus complexe encore toute approche économique. Pour certaines institutions, la 11 production" d'une population à un niveau de connaissances requises, pour répondre à tel impératif industriel ou commercial, pose réelle- 24 ment le problème en termes de rentabilité stricto-sensu. Pour d'autres, l'aspect qualitatif l'emporte, sollicitant moins d'exigences de calcul économique. Cependant, quel que soit l'impératif majeur, une réflexion sur l'efficacité des nouveaux outils engagés s'impose. Une approche complète pour une réflexion approfondie, nécessite une analyse à la fois centrée sur les coûts mais aussi sur l'atteinte des objectifs prévus pour la formation visée. Une étude méthodologique de 1' efficacité se doit, par conséquent, d'être développée parallèlement. 3) Efficacité de l'enseignement assisté par ordinateur : analyseévaluation des effets Le recensement des effets s'articule autour des trois "acteurs" présents : les formés - le formateur - le système de formation. Une étude exhaustive des effets oblige une approche sous double dimension quantitative et qualitative. Effets de l'EAO sur les formés : D'un point de vue qualitatif, on relève : - des effets en terme d'atteinte des objectifs proportion de stagiaires formée au niveau souhaité ; - des effets cognitifs : ce domaine relève directement de la matière enseignée. L'élément clé repose sur les 11 tests" proposés aux stagiaires avant et après la formation dispensée. L'analyse des écarts entre ces deux épreuves fournit la mesure du niveau atteint. La 25 situation de comparaison réelle de groupes· classes utilisant pour les uns l'enseignement traditionnel, et pour les autres la formation avec EAO se montre fort intéressante. Cela nécessite cependant des précautions fondamentales avant toute mise en oeuvre de l'évaluation (identité des objectifs poursuivis - qualité à peu près homogène des formés - niveau général des stagiaires approximativement le même). - des effets sur le temps d'apprentissage : il s'agit de mesurer le temps exact passé par le formé pour acquérir les connaissances nécessaires. D'un point de vue qualitatif, l'évaluation des divers effets mis en évidence s'opère, dans ce cas, par observations sur le terrain et enquête auprès des formés. Elle concerne notamment : -l'individualisation de l'apprentissage, -l'adaptation aux connaissances et rythme de travail du stagiaire, - l'interactivité : dialogue homme/machine, - le degré d'acceptation de l'EAO. Effets de l'EAO sur le formateur : La principale question relevant de l'axe quantitatif appartient à la mesure du temps d'intervention du formateur. Il s'agit de cOnnaître la durée de sa présence lors d'un stage intégrant l'EAO et de la comparer, avec celle d'un cours traditionnel. Du point de vue qualitatif, il s'agit d'évaluer : - la place du formateur. Cet aspect de l'étude porte essentiellement sur l'organisation pratique du cours. 26 - le rôle du formateur dans sa dimension pédagogique .: le formateur voit sa charge de diffusion de connaissances modifiée. Il devient nécessaire d'examiner le nouveau rôle de l'instructeur et d'apprécier son sentiment suite au 11 partage 11 de sa fonction de transfert avec l'ordinateur. - la rigueur pédagogique demandée au formateur. La manifestation de cet effet apparaît, selon le cas, à deux niveaux : conception du didacticiel/intégration dans le cours. D'une part, lorsque le formateur participe à 1' élaboration du didacticiel ou plus spécifiquement à la maquette pédagogique, une réflexion de fond s'instaure. Ce travail d'approfondissement apporte alors un plus fin cadrage des formes et contenus des cours diffusés. Il manifeste par la suite, .des répercussions sur l'enseignement diffusé. D'un autre côté, l'intégration de didacticiels dans un stage livre inévitablement une charpente sur laquelle s'appuiera l'enseignant. Effets de l'EAO sur le système de formation : Les effets sur le système de formation qui peuvent donner lieu à une évaluation quantitative sont essentiellement la durée de la formation et le nombre de personnes formées. En ce qui concerne la durée d'une session de formation avec EAO par rapport à un stage traditionnel, la différenciation entre les notions de temps d'apprentissage (afférent aux formés) et de durée de session (relative au système de formation) est primordiale. Tout gain de temps d'apprentissage n'induit pas nécessairement une baisse de la durée, de session. En toute logique} on pourrait envisager une corrélation entre les deux mais ce n_:est pas obligatoirement le cas. (utilisation par exemple du temps "gagné" à des fins d'approfondisse- 27 ment des notions par diversification des auxiliaires pédagogiques). Cependant, dans la mesure où l'introduction de l'EAO induit une diminution du temps d'apprentissage, il devient logique d'envisager une réduction de la durée du stage. En ce qui concerne 1' effet sur le nombre de personnes formées en même temps ou sur une période plus courte, la présentation de I'EAO comme démultiplicateur de l'action du formateur conduit à s'interroger sur ses capacités de massification de la formation. Certaines entreprises, face à l'ampleur des enseignements à développer, renoncent à recourir aux sessions traditionnelles et escomptent trouver en I'EAO une réponse à leurs exigences. La limitation temporelle d'une session traditionnelle, d'une importance particulière pour les plans de formation, peut induire trois conséquences majeures possibles : 1) soit le nombre prévu de stagiaires se trouve formé sur une période plus courte. Leur opérationnalité est donc plus rapide. Les objectifs de formation se réalisent dans un délai plus court. Les plans s'y afférant peuvent devenir plus ambitieux. 2) soit une quantité plus grande de personnes suivent un stage pour la période initialement prévue. 3) soit, dans l'hypothèse la plus favorable, une quantité plus grande de personnes est formée sur une période plus courte. Les effets sur la qualité de la formation sont potentiellement nombreux. 28 Effets pédagogiques : lors de la pénétration de l'EAO comme support principal des connaissances à transmettre, deux conséquences majeures pour le système de formation peuvent apparaître, à priori, intéressantes : 1)_ Un contenu minimum, celui du didacticiel, se trouve diffusé conformément aux objectifs prévus. Cela peut se montrer particulièrement intéressant lors de formation de public "délicat". Il est effectivement très difficile, pour un enseignant, de trouver la juste adéquation entre un cours traditionnel souvent trop théorique et des situations pédagogiques trop "ouvertes" qui ne permettent aucune manipulation de connaissances. Dès lors, la tendance à dériver devient forte. La présence de l'EAO reconduit le formateur dans le sillage des objectifs. Les responsables du système de formation, sans négliger les difficultés rencontrées par les enseignants, demeurent certains qu'un quota minimum de connaissances a bien été diffusé. 2) Les didacticiels intégrés dans une progression forment des supports sur lesquels les enseignants appuient leur cours. En cas de changement de formateur (situation plus fréquente qu'en formation initiale) un cadre de travail existe. Le nouvel intervenant ne repense pas tout le cursus mais possède déjà un archétype qu'il enrichit simplement de ses propres sensibilités . . Homogénéisation du contenu de la formation dans le temps et dans 1' espace : s'agissant des mêmes didacticiels circulant sur tout le territoire, les diverses unités de l'entreprise possèdent le même outil de travail. Les logiciels_ étant autoporteurs, les mêmes cours contenant les mêmes données et le même vocabulaire sont diffusés à l'ensemble des services concernés quel que soit leur localisation géographique. Il y a constitution, pour les stagiaires, d'un véritable 11VOcabulaire 29 communu. De plus, sur un ensemble de sessions se déroulant sur une période donnée, le même contenu se trouve réellement diffusé. Pour le cas de connaissances stables ou peu évolutives, cette homogénéisation dans le temps peut apparaître importante. Les cours théoriques appropriés à une utilisation future précise se trouvent diffusés identiquement dans toute l'entreprise . . Décentralisation de la formation : les diverses unités de l'entreprise géographiquement dispersées possèdent chacune les didacticiels utilisés. Elles ne sont plus obligées d'envoyer leur personnel dans des lieux centralisés de formation. . Degré d'autonomie dans la réalisation de la formation chaque unité disposant de matériel et de didacticiels peut gérer la formation de ses employés sans attendre une organisation générale demandant beaucoup de temps de mise en place . . Disponibilité totale des cours sur les lieux de travail : dans le cas de libre-accès, le personnel peut travailler suivant son temps disponible y compris la nuit lorsqu 'un système de postes 3 x 8 ou 4 x 8 est en place . . Potentialités sans équivalent : l'utilisation de l'ordinateur permet des activités impossibles à réaliser en enseignemen~ traditionnel. La simulation de situations diverses avec intervention directe de l'élève apporte une dimension nouvelle à la formation. La prise en compte des deux dimensions de l'étude de 1' efficacité représente une approche très large. Toute investigation en ce sens doit aborder tous les effets prévus ou non prévus apparaissant lors de la formation. Pour une analyse scientifiquement valable et non réductri- 30 ce, il est fondamental de réfléchir sur les répercussions quantitatives et qualitatives de l'entrée de cette nouvelle technique sur les trois "intervenants" de la formation. Contrairement à ce que l'on pense communément et aux quelques approches déjà réalisées, la part qualitative apparaît non négligeable. Elle demeure, certes, d'évaluation difficile, mais néanmoins de premier ordre. Uen réflexion sur le rapport coût-efficacité de 1 'EAO amène a fortiori à lui réserver une place toute aussi nette. Cette approche forme un cadre théorique défini à priori. Il convient de l'adapter voire même de l'enrichir lors de toute étude plus particulière d'un 11 terrain 11 donné. Dans les chapitres suivants, nous avons mis en oeuvre cette démarche en vue d'évaluer l'intégration de l'EAO dans sept formations. Chapitre 1 Evaluation coût-efficacité de l'EAO en formation "Initiation à la commande numérique" chez Renault Véhicules Industriels 33 L'introduction de l'EAO chez Renault Véhicules Industriels fait suite à une première expérience, acquise au cours de ces dernières années. Le cours d'initiation à la commande numérique, objet de l'évaluation, tient-compte, pour son organisation, et pour l'intégration de l'EAO d'une certaine réflexion. Cette dernière, certes encore modeste, a été bâtie à partir de situations diverses, vécues et appréciées. De 1' ensemble des "expérimentations" antérieures, quelques idées directrices ont été dégagées. En premier lieu, la nécessité d'un encadrement répondant aux problèmes techniques et pédagogiques s'avère évidente. Même si l'implication du supérieur hiérarchique, dans ce type de formation se trouve fondamentale, celui-ci ne possède pas forcément une compétence pédagogique. Par ailleurs, tout système reposant sur le libre service montre très vite ses limites si un suivi précis des actions de formation ne s'opère pas. Une reprise des acquis avec le formateur apparaît indispensable. Fort de tous ces enseignements, l'EAO se trouve donc intégré dans la formation "Initiation à la commande numériqueu. Son introduction relève donc de deux objectifs complémentaires : apprentissage du contenu et "apprendre à apprendre" 1.1 Présentation d'une session traditionnelle "initiation à la commande numérique" : Afin de situer. le stage d'enseignement "traditionnel", il convient de présenter ce qui se faisait jusqu'alors à Lyon ou St Priest avant l'intégration de l'EAO. 34 La formation se déroulait sur dix journées non consécutives : les quatre premières portant sur la technologie de la machine outil à commande numérique (MOCN), les trois suivantes sur le tournage (terminées par un exercice), les trois dernières sur le fraisage (conclues par un problème). Dans certains cas, un stage spécifique de fraisage ou tournage pouvait être proposé ; il ne comprenait alors que sept jours (quatre en technologie et trois en matière choisie). Ces types d'action ne comportaient aucun travail pratique c'est-à-dire de manipulations sur clavier de MOCN. Ces dernières devaient être vues à l'atelier, soit d'une façon active, soit sous forme de·démonstration, sous la conduite de la maîtrise du secteur. En ce qui concernait les exercices, la correction s'effectuait par le formateur qui prenait en compte les réponses de chaque groupe. Tout reposait donc sur l'instructeur qui appréciait comme "bon" ou "pas bon" le programme préparé. Il apparaît tout de même nécessaire de bien situer la partie de quatre jours en technologie. Elle abordait de manière assez détaillée la description des éléments constitutifs d'une MOCN. D'après les indications livrées par les responsables de la formation, cet approfondissement descriptif n'apporte pas nécessairement une réponse à chacune des personnes présentes et apparaît souvent comme fort long. Selon la provenance des stagiaires (production, maintenance, méthodes ... ), cela s'avère plus ou moins nécessaire. Il est à noter qu'une formation traditionnelle continue d'être assurée à l'unité de Limoges. A la demande de cet établissement, la session 11 lnitiation à la Commande Numérique" relative au tournage et au fraisage se trouve transformée en un stage de huit journées à dominante tour ou fraisage : quatre jours en technologie (connaissances générales de la CN ... ) puis quatre en approche spécifique (tour ou 35 fraisage); La dernière journée est réservée à l'exercice complet par petits groUpes de deux, trois ou quatre. Ces derniers avancent à leur rythme pour parvenir le plus loin possible. Généralement, le programme ·complet avec correction n'est pas atteint, la solution finale étant livrée par papier-listing laissé par le formateur. Aucune manipulation sur pupitre ne se réalise dans le cadre du stage, les formés devant le faire dans leurs ateliers respectifs. 1.2 Introduction de I'EAO dans la formation "initiation à la commande numérique" : Prenant en compte les idées directrices dégagées lors des diverses introduCtions de l'EAO, il a semblé opportun d'utiliser ce nouvel outil en composition avec cours traditionnel et manipulations diverses. Le stage. ses objectifs. l'intégration de l'EAO IntitUlé 11Les bases de la commande numérique en mécanique d'usinagen, ·ce stage représente avant tout une initiation en ce domaine. Diffusé au Centre de Formation de St Priest, il intègre l'Enseignement Assisté par Ordinateur avec la présence d'un formateur. Il s'adresse aux ouvriers professionnels, techniciens, maîtrises, des services de maintenance et fabrication. Quelques pré-requis paraissent souhaitables telles de bonnes notions d'usinage par enlèvement de copeaux. A cette première formation, font suite deux autres stages de spécialisation (Programmation de base Num 760 de six jours) et de perfectionnement (entraînement à la programmation Num 760 de six jours également). 36 Que ce soit sous forme traditionnelle ou avec introduction de l'EAO, les objectifs sont identiques : - Découvrir la structure des machines outils à commande numérique (tour - fraiseuse), leur principe de fonctionnement. - Se familiariser avec le vocabulaire des éléments constitutifs d'une MOCN. - Découvrir le schéma de programmation manuelle, la conduite d'une MOCN, les notions de sécurité et d'entretien préventif. Prenant en compte notre typologie des formes d'intégration de l'EAO, il s'agit d'appliquer cette grille au cas évalué : But apporte une formation nouvelle à l'apprenant Contexte intègre la formation existante Lieu dans le centre de formation Nombre de micro-ordinateurs une salle de type "laboratoire" : 4 appareils Moment pendant le temps de travail Manière intégrée Public captif Unité de base quasi individuelle Nature apprentissage Intégration "mode mixte" Relation au formateur avec suivi 37 Evaluation et déroulement des stages : Après plusieurs entretiens avec le responsable des nouvelles technologies dans la formation chez RVI et plusieurs réunions avec les assistants de formation de chaque usine (moteurs - ponts ~ fonderie - ·méthodes - autocars/autobus), l'ensemble de notre intervention a pu être définie. Par ailleurs, plusieurs rencontres avec le formateur nous ont permis de mieux cadrer l'ensemble des connaissances et savoirfaire dispensés. L'évaluation repose sur notre suivi de trois sessions-de formation (Juin/Juillet - Octobre/Novembre - Novembre/Décembre) dispensées de manière quasi identique par le même formateur. Quelques aménagements s'avèrent nécessaires au fur et à mesure du dérouleinent des stages car l'ensemble relève encore de l'expérimentation. Stage de Juin/Juillet 1988 : L'ensemble de la formation se déroule sur dix jours selon une progression définie globalement. A l'issue d'une présentation générale du stage (explicitation des objectifs, méthode de travail, approche succinte et rapide de la commande numérique .... ),les huit formés s'organisent en binômes. Ils débutent alors le travail sur le' didacticiel 11DIDA CN11 ••• le formateur apportant des explications et èompléments individuels aux différents groupes. Le deuxième jour, avant la reprise du travail devant l'ordinateur, le formateur procède à Une petite récapitulation de quelques éléments clés appréhendés la veille, non soUs forme de cours magistral, mais plutôt de reprise élaborée avec les personnes elles-mêmes. A partir de ce moment, les binômes retrouvent le didacticiel et vont cheminer à leur rythme jusqu'à la fin de la formation. Ils respectent les divers points de passage obligatoires 38 que forment les différents exercices du "contrat11 : exercices 11 tour 11 puis 11 fraisage 11 du didacticiel, deux problèmes de tournage et un de fraisage soumis par le formateur. Il est intéressant de souligner qu'à tout instant, lors de 1' élaboration des programmes de pièces, les formés peuvent recourir à l'EAO pour rechercher telle ou telle information, vérifier un renseignement, réviser une notion mal assimilée (instruction, syntaxe de programmation ... ). Stage d'Octobre/Novembre 1988: Ce stage s'organise selon le même cadre que Juin/Juillet mais sur une durée de huit journées. Globalement le cursus demeure identique. Il faut cependant noter que l'ensemble de tournage (cours + exercices) est entièrement réalisé dans un premier temps. L'étude complète du fraisage y fait suite. Stage de Novembre/Décembre 1988 : De même que celle d'Octobre/Novembre, cette formation se présente sous huit journées. Le corps général d'organisation demeure identique avec cependant quelques aménagements relatifs aux exercices. En effet, l'expérience démontre la nécessité de soumettre de façon régulière de petits exercices afin d'apprécier les acquisitions successives et surtout l'assimilation des notions apprises. Tout au long du stage, de courts exercices sont proposés aux formés de façon à leur faire appliquer ce qu'ils viennent d'appréhender. Pendant l'exécution de ces travaux, le didacticiel demeure à la disposition des binômes qui l'utilisent lors de difficultés rencontrées. 39 Didacticiel utilisé : Le didacticiel "DIDA CN" introduit dans le cadre de cette formation a pour objectif pédagogique l'apport de connaissances élémentaires sur les machines outils à commande numérique et leur mise en oeuvre. Le public cible représente des personnes utilisant des machines outils traditionnelles et de niveau CAP. Ce didacticiel se divise en dix modules intitulés successivement : généralités sur les MOCN, axes d'une MOCN, origines, langage machine, fonctions préparatoires, cycles et micro-instructions, introduction au tournage sur MOCN, exercices de tournage et de fraisage. Objectifs atteints : L'appréciation des objectifs atteints s'établit en référence aux buts prévus du stage, enrichis d'apports spécifiques liés à la façon de travailler. L'évaluation de l'effiCacité interne se place, dans ce contexte, essentiellement par rapport à l'atteinte des objectifs. En effet, le Centre de St Priest ne diffusant plus de formation traditionnelle, nous évaluons l'action pour elle-même, sans comparaison. Certes, des indications sur les sessions traditionnelles antérieures nous ont été données par l'instructeur et diverses personnes du Centre ; cela nous conduira tout de même à livrer quelques termes comparatifs. La perspective première de ce stage concerne la découverte des machines outils à commande numérique et la compréhension de leur principe de fonctionnement au travers de 1' élaboration de programmes. La réalisation de l'objectif n'est pas, en soi, la création d'une pièce par un programme optimisé, le plus performant possible, mais 40 l'utilisation de fonctions de base. Il s'agit, en fait, d'apprendre aux opérateurs, à décoder un programme (le lire et comprendre comment il est écrit) ; cela passe avant tout par une phase de codage. L'ensemble des. exercices proposés a pour objectif fondamental une réflexion sur l'écriture d'un programme avec toutes les questions qui s'y réfèrent.:· Cependant, chaque stagiaire vise la réalisation de la· pièce 11 bonne 11 pour lui, l'atteinte de l'objectif se mesure par la vérification sur pupitre de la validité de l'usinage. 1.3 Etude comparative des coilts d'une formation traditionnelle Puis "mixte" : "initiation à la commande numérique" : Avant de présenter les différents calculs de coüts établis dans le cadre de cette évaluation, il paralt important de souligner le caractère particulier de ces mesures. En effet, la présentation des chiffres propre à chaque entreprise, implique, quelquefois, une approximation réalisée à partir d'informations spécifiques à la Société. Avant de soumettre les tableaux, nous définirons le cadre général des calculs et surtout les diverses hypothèses retenues pour leur élaboration. Cadrage méthodologique et hypothèses retenues : Tout d'abord, les données utilisées pour l'élaboration des coûts sont hors taxes. Les calculs conduisent, dans un premier temps, à l'obtention d'un coût horaire d'enseignement par stagiaire englobant l'ensemble des charges spécifiquement relatives à la diffusion des connaissances. Nous retenons, pour amortissements des micro-ordinateurs et didacticiels, des périodes respectivement de quatre et trois années. Le calcul des coûts s'établissant à partir de données annuelles, 41 le nombre d'heures de diffusion de cours pour un formateur nous a été livré par 1' entreprise. Il est à noter que 1' enseignant assure une tâche de face à face pédagogique ainsi qu'un travail de préparation de cours et de conseil. Le coüt horaire par stagiaire étant un coll.t d'enseignement, il faut, pour approcher un coût de formation, y adjoindre les salaires des formés, les frais annexes (repas ... ), les déplacements. Par rapport à la nature de la formation évaluée, nous présenterons deux études de cas. La première retiendra la présence de stagiaires de Lyon et environs immédiats (St Priest, Vénissieux ... ) ; la seconde prendra en compte des formés en totale provenance d'Annonay. Certes, la situation réelle, lors de la participation de stagiaires éloignés s'apparente plus à une composition mixte du groupe de stage. Il est à noter que les didacticiels utilisés ne proviennent pas du contexte ARDEMI. Aussi nous ne prenons pas en compte le coftt lié à l'adhésion de l'entreprise. Par ailleurs, le coüt de la personne chargée du développement et du suivi des nouvelles technologies dans la formation pour toute la structure RVI n'est pas intégré. Par rapport à l'ensemble de sa tâche, la part relevant de ce stage ressort minime. Comme nous l'avons évoqué dans l'introduction, il est aussi possible de raisonner en termes de coüt du stage (notamment lors de changements dans sa durée).

Les établissements RVI retiennent pour leurs calculs une durée d'amortissement des micro-ordinateurs et des didacticiels de deux années. Cela conduit aux résultats suivants, qui, comme nous pouvons le constater, ne marquent pas une différence notoire. 48 Coût horaire d'enseignement par stagiaire 128,50 F (au lieu de 123,30 F) Coftt horaire de formation par stagiaire : -1er cas : 213 F (au lieu de 208 F) -2ème cas : 222 F (au lieu de 217 F) Cette faible différence liée à la période d'amortissement retenue montre que l'un des principaux points sur lequel nous sommes obligés de faire des hypothèses n'est pas très significatif. Il est important de savoir que certaines mesures qui reposent sur des hypothèses "subjectiveS 11 sont peu sensibles au choix fait par 1' évaluateur. Par contre, si l'on prend en compte le coût global du stage à nombre égal de stagiaires formés, les conclusions se montrent différentes. Le coüt du stage en formation mixte avec EAO se montre inférieur. Dans ce cas, les économies de salaires versés (formateur et formés) réalisées du fait de la diminution de la durée de stage apparaissent plus directement: pour les stagiaires de Lyon, coftt d'une formation traditionnelle (80 h) versus avec EAO (64 h) et économie réalisée par stage : les données sont pour chaque cas en Francs et en heures stagiaires. Stagiaires de Stage en formation Stage en formation Economie sur Lyon traditionnelle mixte avec EAO le coût total (80 h par stage) (64 h par stage) du stage 8 stagiaires 117 868 F (640h-s) 106 496 F (512h-s) 11 372 F 10 stagiaires 131 856 F (800h-s) 118 400 F (640h-s) 13 456 F 12 stagiaires 145 795 F (960h-s) 130 560 F (768h-s) 15 235 F 14 stagiaires 159 790 F (1120h-s) 143 360 F (896h-s) 16 430 F 16 stagiaires 173 785 F (1280h-s) 155 648 F (1024h-s) 18 137 F 49 Si l'on raisonne en coût total du stage, on note effectivement une baisse du coût lorsque l'on introduit les nouvelles technologies informatiques. La raison principale en est la baisse de la durée d'une session (gain de deux jours). lA Efficacité de l'enseignement assisté par ordinateur : analyse des effets quantitatifs et qualitatifs : L'étude de l'efficacité de I'EAO s'articule autour de trois axes. Ces derniers représentent les trois intervenants dans le processus de formation. Nous allons donc étudier successivement les effets sur les formés, sur le formateur et sur le système de formation. Dans chaque présentation, nous distinguons l'aspect quantitatif puis la dimension qualitative des phénomènes évalués. 1.4.1 Effets sur les formés : Effets cognitifs : En début de formation, aucun test de connaissances n'est proposé ; même si certains formés ont déjà quelques notions générales en commande numérique, aucun ne possède de bases en programmation Num 760. La mesure des acquisitions au sein du stage s'opère par la réussite des différents exercices proposés en tournage et fraisage ainsi que par la maitrise des armoires Num 760. Au niveau des deux exercices de fin proposés par le formateur, lés stagiaires 50 doivent écrire le programme de chacune des pièces et le rentrer sur le simulateur (armoire Num 760) qui donne le verdict. Il est important de rappeler qu'en formation traditionnelle, un seul exercice est proposé en tournage et fraisage, puis corrigé collectivement alors que, dans le cas présent, d'autres problèmes ont été traités auparavant. L'ensemble des binômes parvient donc, en des temps différents, à la réalisation de chacun des programmes. Ces derniers, écrits en utilisant les fonctions de base produisent des pièces "bonnes", l'optimisation du programme n'étant pas demandée. Temps d'apprentissage : Une grande diversité apparaît au sein des groupes. Nous prendrons en compte pour ce temps d'apprentissage, celui passé devant le didacticiel, seul diffuseur de la connaissance. Dans ce temps de passage, se trouvent regroupés l'examen du logiciel et les explications spécifiques au binôme apportées par le formateur. A ces durées, il convient d'ajouter l'heure de rappels divers, assurée par le formateur le deuxième jour. Dans le cadre de ces trois phases de formation, il s'avère intéressant d'apprécier différemment la dernière puisque le cursus diffère un peu par rapport aux deux premières. En effet, un plus grand nombre d'exercices ayant été proposés, les stagiaires se sont beaucoup plus trouvés en état de réinvestissement des notions apprises et, par conséquent, ont mieux apprécié leur degré de compréhension. Cela conduit à une plus grande utilisation de l'EAO puisqu'à chaque question insuffisamment comprise, ils retravaillent le module correspondant du didacticiel. La multiplicité de petits exercices soumis aux stagiaires s'avère donc utile car elle permet à chacun une 51 autoévaluation et dans certains cas, une reprise de la leçon. Cette pratique s'adapte très bien au public ciblé pour lequel ce type de formation se présente comme fort difficile. Il peut, de ce fait, travailler en profondeur certains aspects délicats à appréhender. Cela explique, dans le tableau suivant, les différences en temps d'apprentissage (cours EAO et exercices dirigés) entre les deux premières phases et la dernière. Par groupe et selon les sessions : temps d'apprentissage des stagiaires : Groupe 1 Groupe 2 Groupe 3 Groupe 4 Session de juin/juillet 8 h 45 12h25 12h25 14h25 Session d'octobre/novembre !Oh 9 h 30 13 h 17 h Session de novembre/décembre 13h45 17h25 18h55 13h30 De cette évaluation, émergent deux enseignements. Tout d'abord, malgré une grande variété dans la durée de passage devant le didacticiel, une réduction globale du temps d'apprentissage, par rapport à la formation traditionnelle, se réalise. Si l'on considère les six journées (sur les dix) consacrées, en formation traditionnelle, aux tournage et fraisage, cela représente quarante huit heures. L'exercice "final" occupant, par matière, normalement une journée complète, la durée de face à face pédagogique (donc apprentissage) s'élève à trente-deux heures ( 48 - (2 x 8) = 32 heures). En examinant le tableau ci-dessus montrant les temps d'apprentissage sur EAO, les gains de temps se montrent évidents (d'après les chiffres évalués, diminution de 72% (dans le meilleur des cas) à 41% du temps d'apprentissage). Ainsi que nous le verrons, cette baisse induit même une modification de la longueur du stage. 52 Il est à noter par ailleurs que la multiplicité des travaux individuels de réflexion agit sur la fréquentation de l'EAO. Plus les exercices sont nombreux, plus le recours au didacticiel augmente, chaque hésitation ou carence suscitant un retour sur micro-ordinateur. Il peut être, à ce niveau, intéressant de distinguer le temps de travail sur EAO relevant de l'apprentissage et celui appartenant à l'approfondissement de notions (ou à la vérification d'informations). Ce deuxième aspect apparaît significatif pour l'appréciation de 1 'incitation des personnes à travailler seules sur la machine. Ce phénomène conduit l'évaluateur à s'interroger sur l'intérêt des apprenants à s'investir plus complètement qu'en formation traditionnelle. Effets sur la proportion de stagiaires ayant atteint le niveau souhaité : L'introduction de l'EAO dans cette formation semble manifester un effet positif sur la proportion des stagiaires ayant atteint le niveau souhaité. Cela se révèle d'autant plus, que la très grande individualisation de la formation permet un suivi précis des apprenants. En tout état de cause, toutes les personnes sur lesquelles portent les évaluations menées ont atteint les objectifs prévus. L'analyse qualitative des effets de la mise en oeuvre de l'enseignement assisté par ordinateur au niveau des formés, se marque avant tout par une grande individualisation de la formation. Afin de l'apprécier au mieux, sous ses différents aspects, nous avons établi une enquête soumise aux formés lors du bilan de stage. 53 L'observation du stagiaire s'opère, tout d'abord, par l'examen des binômes qui avancent conjointement dans la connaissance. Peu à peu, les questions posées individuellement au formateur montrent les évolutions particulières. Il est clair que l'instructeur connaît les difficultés, les besoins voire même les carences de chacun. Cette relation individuelle rend possible une adaptation et une reformulation du cours propre à la personne qui travaille : le formateur suit donc individuellement l'apprentissage des notions. A l'issue de la session, le formateur peut apprécier les acquisitions de chaque stagiaire, alors qu'en traditionnel, sa vision demeure assez globale. L'introduction de l'EAO, de par la nouvelle approche de travail qu'elle engendre, permet un suivi très précis du stagiaire ... ce qui contribue non négligemment à un meilleur apprentissage. L'introduction de l'EAO marque, sans conteste, une individualisation notoire du travail. Dans le cas étudié, la structure habituelle est le binôme qui, malgré son unité forte, laisse tout de même une part non négligeable à l'individu seul... En ce qui concerne l'adaptation aux rythmes, connaissances et capacités propre à chaque formé, une des réactions positives fortes dégagées à l'issue des formations, recouvre le fait "d'aller à son rythme". Cela apparaît fondamental pour les formés. Ces derniers apprécient de pouvoir revenir en arrière ; ils reconnaissent qu'ils oublient ou négligent involontairement des aspects qu'ils doivent reprendre ensuite. A l'issue de leur première journée de stage, ils laissent déjà apparaître de telles réactions. Ils affirment surtout qu'ils n'auraient pas écouté toute la journée le formateur leur apportant autant d'informations. Il faut d'ailleurs noter l'insistance du responsable pour faire assurer des 54 pauses, l'ensemble des stagiaires étant "absorbés 11 par le didacticiel (travail durant deux heures consécutives devant le micro-ordinateur). L'adaptation aux capacités propres à chaque formé semble évidente. L'évolution différente dans l'acquisition des connaissances et 1' élaboration des exercices le démontrant aisément. La relative hétérogénéité des groupes ne revêt aucune influence quant à l'évolution du cours. Bien au contraire, peu à peu se développent des échanges inter-groupes très riches. L'introduction de l'EAO induit donc une refonte complète de la pédagogie ... ce qui amène progressivement à l'autonomie. Cette dernière se construit peu à peu, d'abord au sein du binôme puis globalement du groupe classe. Au fur et à mesure de l'avancée du cours se constitue plus lentement certes, une autonomie individuelle y compris, chez les moins aptes à une telle attitude. Lors des commentaires libres dans 1' enquête soumise aux stagiaires, réapparaissent sans cesse des points forts qu '-il est intéressant de citer : "progresser à sa vitesse, en fonction de ses connaissances, travailler à son rythme, être autonome et pouvoir revenir sur une leçon non ou mal apprise 11 • Il y a d'autre part l'apprentissage de "savoir-être" et de 11 Savoirfaire". La pénétration de l'EAO dans la formation laisse apparaître des effets absents en traditionnel. Ces derniers contribuent de façon non négligeable, notamment en commande numérique, à un meilleur apprentissage. Ce "savoir-être" apporte non seulement un "plus" au niveau de la formation en elle-même mais se ressent aussi de manière forte sur le poste de travail. La très large autonomie laissée par l'EAO aux apprenants leur fait très vite appréhender la nécessité de prises de notes bien présentées et bien articulées. La possibilité de pouvoir revenir en arrière au sein du didacticiel incite les formés à une prise 55 de notes structurée. Cela se retrouve peu après, lors de la création de programmes. Progressivement, les formés ressentent l'obligation de venir à l'équipement Num 760 avec quelque chose de construit accompagné d'annotations adéquates. Un autre aspect relève de l'incitation à recueillir les informations nécessaires et surtout à savoir les rechercher. Cela apparalt tout d'abord avec le didacticiel ; les formés rappellent tel ou tel module pour réviser une notion puis, par la suite, doivent chercher dans les fascicules appropriés les erreurs émergeant du programme et signalées par le simulateur. Ce recueil d'informations, totalement nécessaire lors de la mise en oeuvre d'une machine à commande numérique est fondamental. Il s'agit d'apprendre aux formés à savoir aller chercher une donnée soit dans un des nombreux livrets accompagnant la MOCN soit auprès d'une personne compétente capable de la fournir. Cette acquisition du "savoir-faire" se marque par le travail en binôme. Les formés parviennent plus facilement et plus naturellement à réagir face à une situation, à expliquer à l'autre, voire même à argumenter et défendre leur réponse. Cette communication inter-individuelle entre les formés modifie totalement la nature du système d'apprentissage. Globalement, de ce type d'action, découle une incitation à l'autonomie. On peut raisonnablement penser que cette nouvelle approche induit une acquisition de méthode de travail avec une ouverture vers l'esprit de synthèse, de structuration et de clarté dans les informations recueillies et notées. Au-delà de toutes ces attentes qui, effectivement, se réalisent de manière inégale (du fait de la relative hétérogénéité des groupes), se dessine l'objectif d'apprendre à apprendre. 56 Une autre dimension primordiale liée à la mise ·en oeuvre de l'EAO est l'interactivité. L'appréciation de l'interactivité relève avant tout de la nature du dialogue homme/machine. Dans le cadre de l'enquête proposée aux formés, il est possible d'appréhender le degré d'interactivité du didacticiel proposé. D'après les réponses fournies, les vingt-deux apprenants notent un dialogue permanent tout au long du cours et ressentent le fait d'être actifs au travers d'Une conversation avec l'ordinateur. L'échange leur paraît riche, accompagné de nombreuses interventions. La machine les sollicite beaucoup et les fait réagir souvent. Un des éléments essentiels de l'apprentissage relevant de la reprise et du réinvestissement des connaissances nouvelles, les stagiaires notent cette impression effective de maniements successifs et répétés de concepts nouveaux. Il apparaît sans équivoque que ces interventions quasi constantes de l'ordinateur imposent aux élèves une attention beaucoup plus soutenue. D'une manière générale, le didacticiel utilisé apparaît développer une assez forte interactivité, l'ensemble des questions relatives à ce domaine trouvant des réponses positives. En ce qui concerne le degré d'acceptation du didacticiel et de l'EAO, les questions posées relatives à l'appréciation du didacticiel "DIDA CN" revêtent des réponses plutôt positives. Les explications apportées apparaissent pour tous comme claires et suffisantes. L'ensemble du cours se perçoit comme intéressant, amusant, attrayant, composé d'un vocabulaire simple permettant d'apprendre beaucoup. Les parties fondamentales sont estimées bien mises en relief et l'utilisation des couleurs bien étudiée. L'EAO, dans son ensemble, dégage, semble-t-il, un caractère positif. A l'exception d'un stagiaire pour lequel l'ordinateur n'apparaît 57 convivial qu'à partir du deuxième jour, l'effort d'adaptation à ce nouvel outil reste limité. La légère appréhension des premières minutes de contact avec la machine, laisse vite la place à une assurance de manipulation notoire. Ce type de formation, au travers des réponses fournies, demeure à développer puisque l'BAD paraît très intéressant, moins fatigant et très efficace pour apprendre. Les formés notent une impression de comprendre beaucoup plus facilement et rapidement. Par ailleurs, la durée d'une séance EAO ne se ressent ni trop courte, ni trop longue ; 1 'inclusion de cette technologie rend subjectivement la durée de la formation plus courte par rapport à l'enseignement traditionnel. Effets sur le formateur : Il est à considérer, dans cette évaluation, plusieurs dimensions, quant à la présence du formateur. L'intégration de l'BAD dans la formation relève avant tout d'un plus grand travail individuel au travers d'une relation homme/machine. La tendance, lors des utilisations de l'BAD est tout de même le plus grand effacement possible du formateur ... un autre objectif parallèlement visé étant 11 apprendre à apprendre seul 11 • Cela incite donc l'instructeur à quitter la salle de façon à ce que les formés s'autonomisent dans leur travail. Lors de la formation de Juin/Juillet, ses absences ont été plus importantes, alors que pour les deux phases suivantes, un encadrement plus fort s'est avéré nécessaire. Cela semble avant tout lié au public un peu différent des deux dernières sessions. Son comportement vis-à-vis de la formation relevait d'une moins grande motivation. 58 Nous -n'avons pas opéré de mesure exacte du temps de présence dans la salle mais évaluerons grossièrement à 80% du temps pour la phase de Juin/Juillet et 90% pour les deux suivantes. Pour chacune des sessions, l'enseignant intervient collectivement une heure trente pour présenter le stage, quelques idées générales sur la commande numérique et pratiquer un petit bilan rapide de fin de journée. Corrélativement, une heure de bilan de fin de stage permet de connaître les réactions et critiques des stagiaires à l'issue de la formation reçue. Globalement, incluant ces plages "communes 11 à toutes les . sessions, nous obtenons approximativement les temps d'intervention magistrale pour chacune des trois phases : * Session de Juin/juillet : 3 h 40 * Session d'Octobre/Novembre : 7 heures * Session de Novembre/Décembre : 5 h 20 Les différences importantes entre ces trois durées semblent s'expliquer par le degré d'hétérogénéité des groupes, des progressions dans la connaissance et par le niveau général des classes. L'interprétation de ces écarts est à manier avec prudence car, dans ce type de pédagogie, l'élément essentiel repose sur la relation binôme, ordinateur, formateur. Comme on peut le constater, l'intervention magistrale face au groupe complet revêt, pour ce cadre de formation, une place mineure. L'apport essentiel provient du didacticiel, et surtout de la "reformulatian" du message, par l'enseignant, auprès des binômes. Des possibilités d'absence du formateur sont concevables mais, en l'état, peu significatives par rapport à la durée totale du stage. 59 Il s'agit, dès lors, d'examiner plus en détails la nouvelle tâche de l'instructeur. C'est ainsi qu'une étude qualitative sur sa place et son rôle trouve son importance. Cette partie, menant réflexion quant à la place, au rôle et à la rigueur pédagogique imposée par l'EAO à 1' enseignant se constitue à partir de l'étude du terrain et de deux enquêtes : l'une adressée aux formés et l'autre au responsable de la diffusion de la connaissance. Place du formateur (dimension pratique): L'enseignant se "glisse" peu à peu dans l'EAO et constitue progressivement sa place. Sa principale difficulté est d'être présent au moment adéquat tout en se montrant de plus en plus discret. Devenant plutôt un consultant, il s' 11 effacen peu à peu pour parvenir à des interventions très ciblées et très personnalisées. Sa place s'amoindrit puisqu'il n'est plus le centre du groupe. Cette nouvelle situation ne perturbe en aucune façon le formateur rencontré. Selon lui, son intervention au sens magistral du terme diminue pour parvenir à un enseignement spécifique appliqué à tel binôme sur tel sujet. C'est alors un enrichissement notoire de sa place. Au fur et à mesure du déroulement de la formation, 1' enseignant s'absente volontairement de la salle. Au début, cela trouble quelque peu les stagiaires mais l'autonomie de travail grandissant, l'absence se remarque de moins en moins. Contrairement à l'ordinateur qui fournit questions, commentaires et même réponses, s'exerce chez l'instructeur toute une analyse particulière des binômes et de leurs réactions ; cela induit même parfois des interventions spécifiques de sa part. Même si sa place évolue dans un sens moindre, son rôle. n'en demeur_e pas moins fondamental... bien que quelque peu modifié. 60 R6/e du formateur (dimension pédagogique) : Il s'agit, pour lui, d'abandonner en partie le transfert général de connaissances au profit de l'assistance. La relation pédagogique détenteur du savoir/groupe devient plus individuelle (binôme ou personne précise). Au-delà de la reprise des apprentissages, l'enseignant reformule et adapte le message à chaque individu. Bien au-delà de cette individualisation, le formateur connaît de manière plus approfondie son public et peut, par conséquent, devenir encore plus exigeant avec ceux, notamment, qu'il sent plus avancés. Par contre, il lui est possible d'affiner des explications, et donc de faire mieux comprendre les concepts aux élèves marquant plus de difficultés. Le rôle du formateur, par rapport à l'enseignement traditionnel, diffère donc totalement ; le contact individuel le rend véritable "adaptateur" du message au groupe chargé de se 1' approprier. De plus, ses interventions en termes de "savoir-travailler" prennent une place importante : prises de notes, synthèse des points abordés, rédaction et correction des programmes... Quoi qu'il en soit, se maintient une habitude d'appel au formateur. Chaque formé ressent la nécessité d'un recours au "détenteur du savoir", à celui qui conduit (même si son rôle diminue) le groupe. Dans les décennies futures, ce rôle de magister s'amenuisera peut-être peu à peu, le nouveau public à former s'habituant progressivement à l'autoformation ou tout au moins, à une relative prise en charge par rapport à 1' acquisition du savoir. Rigueur pédagogique demandée au formateur dans la conception et la réalisation de la formation : Dans le cas présent, l'utilisation de l'EAO ne forme pas, pour l'instructeur interrogé, un élément canalisateur trop fort. "L'imposi- 61 tion" d'une plus grande rigueur s'applique plus .à la; réflexion pédagogique. Dégagé de la première diffusion du contenu, l'enseignant se doit de trouver tous les moyens pour une explication appropriée. Cela nécessite donc une analyse plus fine de la difficulté rencontrée et l'obligation de posséder plusieurs formules 'd'explicatiOns. Le formateur prépare cette souplesse face aux réactibD.s diverses des formés par rapport à l'ensemble des difficultés susceptibles de surgir tout au long du stage. 1.4.3 Effets sur le système de formation : Le caractère encore expérimental et limité dans le temps permettra seulement d'apporter quelques résultats significatifs et surtout des hypothèses pour l'avenir. En effet, toute réflexion quant à· la nature des effets sur le système de formation impose un recul temporel suffisant. L'intégration de l'EAO dans cette formation en commande numérique induit un effet réel sur la durée d'une session de formation. Pour atteindre les m€mes objectifs pédagogiques, huit journées au lieu de dix s'avèrent nécessaires. Ce gain s'est confirmé tout au long des sessions évaluées. Il faut noter, parallèlement, une meilleure connaissance individuelle des formés, ce qui ne permet pas d'envisager une réduction de temps sans vérification réelle des acquis. Ce gain de deux jours est un effet important pour le système de formation puisqu'il peut avoir d'importantes répercussions. En effet, une telle diminution s'appliquant sur plusieurs stages, des possibilités d'organisation de sessions supplémentaires apparaissent. Par ce biais, l'emploi de ce nouvel outil rendra 62 possible, à terme, dans ces mêmes conditions d'utilisation, une formation d'un plus grand nombre de personnes. Sans anticiper sur des résultats perceptibles plus tard, il est possible d'envisager des répercussions sur le cycle suivant. Aucun groupe (ayant suivi l'EAO) n'étant revenu en formation 11Base de programmation Num 760", l'impact relève d'hypothèses. Il s'agit, parallèlement à l'amélioration permanente du premier niveau, d'analyser le second et éventuellement d'apporter les modifications nécessaires. Le réinvestissement permanent des notions apprises et l'acquisition d'une forme de travail individuelle devraient générer des influences sur le second cycle. Ce dernier débutant par un jour et demi d'exercices de rappel, il sera facile d'apprécier les évolutions du groupe. De plus, toute révision habituellement assurée par le formateur, pourra l'être avec l'EAO. Dès lors, ces reprises de cours, nécessaires pour la suite, glissent là encore vers une plus grande individualisation. Chacun reverra le, ou les modules spécifiques à ces carences et trouvera de ce fait une adaptation à ses propres difficultés. S'ils se vérifiaient lors de la prochaine session 11Base de programmation Num 760", ces apports pourraient aussi développer des effets sur la suite du cursus ; des modifications apparaîtraient envisageables et seraient apportées en fonction des constats. Partant d'observations réalisées au niveau des stages et d'entretiens avec divers responsables de formation, quelques directions pour les années à venir se dessinent. 63 Le système de formation, sans cesse à l'écoute des différents services de l'entreprise, tente d'accorder une réponse à chacun des besoins. Les sessions de Commande Numérique accueillant des personnes d'origines professionnelles diverses (utilisation, méthodes, gestion, maintenance ... ), n'apportent pas nécessairement satisfaction complète. Des remarques de ce type reviennent sans cesse de la part des formés. Dès !989, un réaménagement du cours, avec complément spécifique selon le cadre d'activité, devrait voir le jour. Le corpus théorique, les exercices de· réinvestissement seraient modulés par rapport aux attentes. La plateforme théorique indispensable quel que soit le secteur, demeurerait apportée par 1 'EAO et complétée par le formateur. L'individualisation se doublerait de la personnalisation de la formation. Cette totale adéquation entre le besoin exprimé et l'apport effectif des connaissances serait un effet considérable de l'EAO à la fois sur la formation et sur le poste de travail. Corrélativement, l'objectif d'"apprendre à apprendre", devrait, dans quelques années redéployer le système de formation. La création de centres-ressources avec animateur viendrait en complément des formations conventionnelles. Ce type d'enseignement intégrant l'EAO, réalisé essentiellement à St Priest, n'induit, à l'heure actuelle, aucun effet sur la décentralisation des stages. Quoi qu'il en soit, la libre circulation des disquettes sur les différents sites imposerait la mise en place de démultiplicateurs. Il serait alors certain que le même contenu se diffuserait sur toutes les unités de l'entreprise. Une véritable homogénéisation des contenus développés à partir des mêmes cadres, verrait le jour. Pour l'heure actuelle, la priorité reste aux centres de formation. Les toutes prochaines années apporteront des éiéments de réflexion plus précis. La mise en oeuvre progressive de l'EAO à partir d'un véritable tâtonnement expérimental fournira un terrain 64 riche et une expérience suffisante pour approfondir les effets qualitatifs sur le système. 1.5 Rapport coût-efficacité de I'EAO mis en oeuvre en "Initiation à la commande numérique 11 : Avant d'établir, à 1 'issue des formations évaluées, les conclusions relatives à la mise en oeuvre de l'EAO, il est important de bien situer le niveau des connaissances et savoir-faire à acquérir par rapport au public ciblé. Tout d'abord il faut considérer ce cours comme difficile pour des personnes agissant chaque jour dans le concret, opérant par manipulations réelles et abordant tel ou tel problème par tâtonnement expérimental. Le niveau d'un tel enseignement sollicite un pouvoir d'abstraction relativement fort et un degré très important d'anticipation face à l'action. Il est bien certain que l'élaboration de programmes en commande numérique, objectif non visé en soi mais passage quasi obligé pour décoder, par la suite, un programme courant, n'est pas de première évidence. Les stagiaires, remarqués comme de bons professionnels, abordent une démarche intellectuelle de résolution de problèmes qui contraste avec leur vécu habituel manifestement très empirique. Ayant bien situé le cadre général de ces actions de formation, il apparait dès lors opportun de réfléchir sur le rapport coût-efficacité. Ainsi que nous avons pu le constater lors de l'étude des coûts, l'introduction de ce nouvel outil induit un surcoût lorsque l'on raisonne en collt heure/stagiaire. Par contre, si l'on prend en compte le coût du stage à effectif identique, on voit apparaitre une baisse du coût. Il est certain que le gain de deux jours de formation contribue à limiter les surcoûts liés au matériel supplémentaire nécessaire. La 65 conclusion à tirer, quant aux coûts, dépend de l'indice de comparaison choisi. Si l'on retient la, comparaison en termes de coût de stage, la conclusion est pleinement favorable. Par contre, si l'on regarde le coût heure/stagiaire, un surcoût apparaît. Ce dernier n'est cependant pas considérable puisqu'il représente une augmentation de 13% du coût de formation traditionnelle. Ayant apprécié les différents aspects de la problématique des coûts, il devient opportun d'envisager les éléments susceptibles d'améliorer l'efficacité. Pour cela, une reprise des divers effets de la mise en oeuvre du nouvel outil permettra d'envisager pour chacun d'eux les possibilités d'amélioration (voir synoptique, en fin de chapitre, sur les formés, le formateur et le système de formation). Tout d'abord, il paraît difficile d'abaisser encore le temps d'apprentissage. Seule une individualisation très forte (ce qui oblige une évaluation préalable de la personne) pourrait permettre d'amenuiser drastiquement cette période d'acquisition. Il est bien sür pOssible à des personnes connaissant déjà un peu la commande numérique d'aborder plus rapidement les exercices individuels. Une question se pose alors : ont-elles encore une place en ce stage d'initiation? Par ailleurs la très forte individualisation du travail, renforcée par une relation personnelle avec l'ordinateur assure un effet non négligeable sur la proportion des stagiaires ayant atteint le niveau souhaité. Cela est d'autant plus vrai qu'une réelle appréciation des acquisitions s'avère possible au niveau de chacun des formés. Pour ce qui relève du temps d'intervention du formateur, il est possible d'envisager à terme une présence un peu plus partielle. Elle ne peut, dans ce contexte, baisser beaucoup, la reformulation individuelle gardant toute son importance. La session ayant déjà diminué de deux jours, il semble, là encore, difficile d'envisager une durée bien moindre. Pour certains stagiaires ayant déjà quelques 66 notions, ou d'importants pré-requis, un gain supplémentaire d'une journée apparaît possible. Quoi qu'il en soit, la durée de huit jours semble bien adaptée au public ciblé. L'amélioration de l'efficacité repose aussi sur d'autres facteurs qualitatifs donc non mesurables. Ils revêtent néanmoins, comme nous l'avons étudié, un caractère fondamental et agissent même sur les éléments quantitatifs. Plus généralement, il est certain que de plus en plus, chacun trouvera en formation une réponse réelle à ses besoins spécifiques, et ce, poUr son propre secteur d'activité. Cette spécificité s'établira à double niveau : celui de l'individu et celui du service dans lequel il travaille. Bien au-delà de tous les apports relatifs à l'initiation à la Commande Numérique, un autre point fondamental, qui sera capital pour aborder les années futures se doit d'être pris en compte : apprendre à apprendre. L'évolution rapide des postes de travail ainsi que leur spécificité croissante induiront inéluctablement une nécessité de se former. La demande de formation trouvera-t-elle en face d'elle une offre suffisante ? Le rééquilibrage de l'inadéquation quasi probable entre les deux passera certainement par une démarche individuelle. 67 Renault Véhicules Industriels Tableau synoptique des effets de l'EAO par rapport à une formation traditionnelle 111nitiation à la Commande Numérique" Evaluation quantitative Approfondissement des notions par réinvestissement dans un plus grand nombre d'exercices (8 au lieu de 2) Réalisation de tous les exercices par tous· les stagiaires Baisse du temps d'apprentissage (plus de temps dégagé pour les exercices) Evaluation qualitative Meilleur suivi de chaque stagiaire Individualisation très forte de l'apprentissage : travail à son propre rythme Activité intra binôme et inter binômes forte : développement du travail par équipes Autonomie dans le travail ; retour arrière, reprises, révisions toujours possibles Interactivité : dialogue permanent avec la machine Apprentissage d'un "savoir-être" :prise de notes (articulation, clarté), recherche d'informations ...

Chapitre 2 Evaluation coût-efficacité de I'EAO en formation "Connaissance de l'entreprise" au Centre de Formation de la petite entreprise et du commerce (CEPC) de la Chambre de Commerce et d'Industrie de Lyon 71 Dans le cadre du dispositif de l'alternance pour les jeunes, la Chambre de Commerce et d'Industrie de Lyon (CCIL) propose les différents stages relatifs aux principaux contrats. Leur réalisation, leur suivi, et la gestion de leur financement relèvent de la Délégation à la Formation Continue et à l'emploi, service de la CCIL. A chacun des trois types de contrats (initiation à la vie professionnelle, adaptation, qualification), correspond une formation spécifique comprenant quelques parties identiques. Parmi celles-ci, se trouve le module 11 Connaissance de 1' entreprise" intégrant 1' enseignement assisté par Ordinateur, objet de notre évaluation. Avant d'aborder plus spécifiquement cette dernière, quelques considérations générales relatives à ce jeune public s'imposent. Tout d'abord, la spécificité du cursus scolaire de ces personnes, ainsi que leur grande instabilité professionnelle les rendent, pour la plupart, fort démotivées face à toute formation. De plus, une vision négative de l'entreprise, apparue à l'issue de leurs divers emplois précaires ne les incite pas à une curiosité aigüe en ce domaine. Le caractère contraignant ou obligatoire de la présence à ce stage ne contribue pas à une réelle motivation. Il s'agit, par conséquent, d'apporter à ces jeunes une formation très proche de leur vécu quotidien, intégrant une pédagogie adaptée. Face à ces difficultés inhérentes au stage lui-même, la délégation à la formation continue, ainsi que le Centre de Formation de la Petite Entreprise et du Commerce (CEPC) ont, sans cesse, tenté d'améliorer les conditions d'enseignement. 72 Lors des premières sessions, le formateur intervenait de manière magistrale et diffusait unilatéralement les connaissances. Très vite, les stagiaires renouaient avec le milieu scolaire et devaient rester passifs durant tout le cursus. Un jeu fut alors introduit ; il apportait une certaine action mais faisait passer une idée vieillie de 1' entreprise. L'arrivée des techniques modernes de communication incita à envisager l'intégration de films video au sein de la formation. En tout état de cause, il s'agit de trouver des outils pédagogiques permettant une valorisation du jeune, développant ainsi un certain intérêt. L'animation repose avant tout sur 1' expérience personnelle, et a pour obligation de proposer des situations actives. Dans ce contexte, la naissance de l'ARDEMI ouvrit l'opportunité d'une mise en oeuvre de l'EAO. La création du didacticiel relatif à ce type de public se substitua à l'élaboration d'un film vidéo. Ce nouvel auxiliaire pédagogique va-t-il permettre d'améliorer la formation ? Contribuera-t-il à développer chez les stagiaires, le goût et le désir de se former ? Autant de questions difficiles auxquelles doivent répondre les responsables, afin de toujours mieux aider ces jeunes intégrant peu à peu la vie professionnelle. 2.1 Introduction de l'EAO dans la formation "Connaissance de l'entreprise 11 : Partant des préoccupations inhérentes à ce public jeune et spécifique, il a donc semblé opportun d'introduire l'enseignement assisté par ordinateur. 73 Présentation du stage : Le stage intitulé 11Connaissance de l'~ntrepris;e" s'adresse aux jeunes en contrats d'alternance. Diffusé au Centre dè Formation de la Petite Entreprise et du commerce (CEPC) à Lyon-Vaise, il porte sur une durée de deux jours et demi. Une demi-journée complémentaire prise en charge par une personne de la Délégation à la Formation Continue et à l'Emploi (DFCE) de la CCIL traite la législation.Le statut juridique du stagiaire, ainsi que ses droits et obligations sont abordés. Pour notre part, nous considérons les deux jours et demi relatifs à la découverte de l'entreprise. Ces objectifs sont : - la sensibilisation à une culture et à une image moderne de 1' entreprise. -l'insertion du jeune dans la vie professionnelle par une connaissance concrète de 1' entreprise . - la diffusion d'une meilleure compréhension du fonctionnement de l'entreprise et de la place occupée par le stagiaire en son sein. - l'incitation à la réflexion et au désir d'en savoir plus afin de renouer avec la formation et ses opportunités. Forme d'intégration de l'EAO : Prenant en compte la typologie des formes d'intégration de l'EAO telle que définie par nos soins, il s'agit d'appliquer cette grille au cas évalué: 74 But apporte une formation nouvelle à l'apprenant Contexte intègre les formations existantes Lieu dans le centre de formation Nombre de micro-ordinateurs une salle de type "laboratoire" : 8 appareils Moment pendant le temps de travail Manière intégrée Public public à motiver Unité de base quasi individuelle Nature apprentissage Intégration "mode mixte" Relation au formateur avec alternance Déroulement des stages et évaluation: La formation diffusée au CEPC se présente sur deux jours et demi et intègre un enseignement "mixte" avec' alternance d'EAO et de traditionnel. Le formateur appuyant son intervention sur un module du didacticiel dégage et reprend les notions clés. Peu à peu, une ouverture du sujet s'opère soit sur son initiative soit par questions spécifiques des stagiaires. Lors du passage de l'un à l'autre, le groupe change de lieu. La salle informatique se trouve au premier étage, les cours étant dispensés au second. Cela ne doit pas être considéré comme un détail ; en effet, les jeunes trouvent dans ces mutations une certaine trève pour mieux appréhender la suite. Il ne faut pas négliger la très faible capacité d'attention qu'ils développent et, par conséquent, la 75 nécessité pour eux d'être actifs physiquement et intellectuellement. Ces déplacements obligés leur permettent donc une reconcentration pour aborder la plage suivante. Cela apparaît d'autant plus vrai que, pour un ou deux cas particuliers de demi journées vécues entièrement en traditionnel (indisponibilité partielle de la salle informatique), trois heures d'enseignement traditionnel s'écoulaient difficilement (malgré quelques pauses). Il ne s'agit absolument pas de cours au sens habituellement entendu, les stagiaires ne prennent aucune note manuscrite (ou très peu). Afin de les faire mieux réfléchir sur la nature même de 1' entreprise (vécue par eux comme un tout indissociable), il est utile de 11 Casser" cette entité et de recomposer les diverses parties en un 11 tout" moins figé. D'autre part, il s'agit de montrer qu'elle évolue dans un contexte général dont le responsable a obligation de tenir compte. Toute une approche positive s'avère donc nécessaire. Dans 'bien des cas, une reconstruction totale de la notion s'impose. Cette double difficulté de recomposition des idées et de remotivation des élèves doit être surmontée au mieux. Une appréciation positive du stage doit être véhiculée par les contractants lors de leur retour en poste. Dans le cas présent, le souci d'efficacité se double de celui de qualité. Mise en oeuvre de l'évaluation : Dans un premier temps, nous avons pris contact avec ce public et avec plusieurs personnes intervenant auprès de lui. Nous. avons ensuite réalisé une approche précise du contenu d'enseignement (afin d'élaborer des tests de connaissances). Une présence régulière et une participation effective à de nombreuses sessions nous ont permis de 76 mener à bien cette évaluation qui porte sur 123 stagiaires. Par la suite, nous avons tenté, par notre assistance aux cours et lors de divers entretiens tant avec les formateurs qu'avec le responsable administratif du stage, de bien cerner chaque groupe. Le CEPC ne diffusant désormais plus de cours traditionnel comme auparavant, nous ne disposons d'aucun cadre de comparaison entre les deux formes d'enseignement. Didacticiel utilisé : Le didacticiel réalisé dans le contexte de l' ARDEMI par la Chambre de Commerce et d'lodustrie de Lyon, propose essentiellement des situations concrètes. Son objectif essentiel est de permettre au stagiaire de mieux se situer dans 1' entreprise et, corrélativement, de comprendre les flux entrée/sortie. Pour cela, llD cadre réel se met en place avec implication de l'apprenant. Par l'intermédiaire de différentes situations ludiques, le formé découvre en six modules les grandes fonctions de 1' entreprise créée par six amis (Vente-Finances-Production-Approvisionnement-Personnel-Direction générale). 2.1.6 Objectifs atteints : L'atteinte des objectifs fixés s'apprécie avant tout qualitativement, par une vision plus positive de l'entreprise. Cela induit une meilleure compréhension de son fonctionnement, et l'acquisition de notions fondamentales spécifiques. Ces dernières, abordées lors du stage, relèvent d'apports cognitifs quantitativement évaluables. Les 77 écarts entre les deux tests de début et de fin permettent de les analyser. Cependant, cela s'avère être un des éléments d'appréciation parmi d'autres. Ce qui est visé se rapporte avant tout au degré de satisfaction du jeune par rapport au stage et à son insertion réussie au sein de l'unité de travail. Comme indiqué ci-avant, notre étude ne peut être totalement comparative, aucune formation de ce type n'étant désormais diffusée selon le mode traditionnel. L'évaluation de l'efficacité interne se place, dans ce contexte, par rapport à l'atteinte des objectifs. 2.2 Etude comparative des coûts d'une formation traditionnelle puis 11mixte" : "Connaissance de l'entreprise": Cette étude comparative des coûts a pour base les calculs relevant d'une formation traditionnelle telle qu'elle était réalisée avant l'introduction de l'EAO. D'après les indications des différents responsables de ce type de formation, le stage se présentait effectivement de manière similaire, mais avec intervention de l'enseignant. 2.2.1 Cadrage méthodologique et hypothèses retenues : Avant de présenter pour chacun des cas le détail des coûts, il nous faut indiquer que seuls les coû.ts opérationnels seront pris en compte. Nous ne pouvons intégrer la part (quasi négligeable par rapport à l'ensemble des prestations fournies) de la direction générale, et des services fonctionnels rapportés à la formation envisagée (CCIL). 78 Par ailleurs, nous sommes en possession de chiffres relatifs à tout le centre de Vaise ; cela nous oblige de faire apparaltre la part relative au stage "Connaissance de l'entreprise". Les données mises à notre disposition appartenant à des documents internes non publiables, nous ne pouvons qu'indiquer les différents ratios utilisés (chiffres hors taxes). Dans le cas de cette évaluation, nous nous plaçons dans le contexte CEPC, et ne prenons, par conséquent, pas en compte le salaire et les frais de déplacement des formés. Ces derniers sont pris en charge par les entreprises. Il est vrai que le coût de formation s'en trouve sous-estimé. Cependant, la base de comparaison des coûts étant la même ( coüt horaire d'enseignement par stagiaire), il est tout de même intéressant d'examiner leurs rapports selon -les deux modes d'enseignement. L'introduction de l'EAO limitant, actuellement, le nombre de stagiaires à 16, nous proposons les calculs élaborés à partir de ce chiffre ; l'effectif en traditionnel était de 18. En ce qui concerne l'amortissement des matériels informatiques, nous conservons une période de quatre années pour les micro-ordinateurs et de trois pour le didacticiel. 79 Collts d'une formation traditionnelle ; 665 heures annuelles de diffusion en "Connaissance de l'entreprise" Année 1987 Groupe de 18 stagiaires- Durée: 2 jours et demi: 17,5 heures Personnel .

U.l Effets sur les formés · Effets cognitifs : Ainsi que nous 1 'avons déjà mentionné, nous soumettons en début et fin de stage un test de connaissances élaboré par nos soins (avec les conseils des différentes personnes rencontrées à la Chambre de Commerce). Sa création a suscité beaucoup de difficultés puisque la formation aborde, de manière générale, beaucoup de points clés relatifs à l'entreprise. De plus, les stagiaires, pour une grande partie, ne sauraient apporter des définitions, ou résoudre des problèmes quelque peu structurés. C'est pour cela que l'exercice proposé se présente sous forme d'affirmations justes ou fausses. La même 82 structure de questions se trouve posée initialement et à postériori. Il s'agit, en l'occurrence, de mesurer un progrès par rapport au stade de départ, les écarts entre les deux notes donnant une progression par rapport aux .connaissances premières. Cela permet d'apprécier en quoi la formation reçue autorise une meilleure appréhension de notions fortes. Le tableau ci-dessous présente, pour chaque groupe de stage, les moyennes des notes obtenues aux différentes passations du test. CEPC Lyon stages Initiale Finale Ecarts Stage du 5 au 7 juillet 1988 14,64 16,56 + 1,92 Stage du 11 au 13 juillet 1988 . 13,81 15,36 + 1,55 Stage du 22 au 24 août 1988 13,56 15,17 + 1,61 Stage du 29 au 31 août 1988 12 13,89 + 1,89 Stage du 27 au 29 septembre 1988 14,85 15,78 + 0,93 Stage du 4 au 6 octobre 1988 16,15 17,60 + 1,45 Stage du 5 au 7 octobre 1988 14,58 15,82 + 1,24 Stage du 11 au 13 octobre 1988 15,68 16,54 + 0,86 Stage du 2 al). 4 novembre 1988 15,5 16,6 + 1,1 Stage du 8 au 10 novembre 1988 12,6 13,4 + 0,8 Stage du 16 au 18 novembre 1988 14,2 16,41 + 2,21 A la lecture de ce tableau, un constat général s'impose: les nOtes tant au début qu'à la fin du stage apparaissent élevées. Cela peut 83 remettre quelque peu en cause la validité de l'exercice proposé. Ainsi que nous l'avons déjà mentionné, toute élaboration de test face à un tel public se montre difficile. Dans tous les cas, on observe des écarts positifs entre les deux tests. Temps d'apprentissage : Comme nous avons déjà pu le constater, l'apport cognitif repose sur l'EAO. Il est diffusé par modules examinés séparément. Lors du premier contact avec la salle informatique et le matériel, une séquence d'une quinzaine de minutes permet de présenter le micro-ordinateur, le clavier et quelques manipulations simples relatives au didacticiel. Immédiatement après, les formés abordent la partie introductive. Dans l'ensemble, les temps de passage s'étalent entre vingt et trente minutes. Cette durée est très rarement dépassée. Selon les leçons appréhendées, les temps augmentent _ou diminuent selon l'intérêt des stagiaires pour cette formation. Sans livrer une présentation exhaustive des chiffres, un certain nombre d'enseignements se dégagent. Tout d'abord, il ressort au travers de nos constatations sur le terrain, que les stagiaires les plus motivés ont un temps de passage devant l'EAO, plus élevé. Les binomes terminant souvent les derniers sont les "éléments moteurs" du groupe classe. Cela s'explique par un échange plus riche entre eux avant de livrer une réponse. A l'inverse, les équipes terminant les premières, n'apparaissent pas comme celles connaissant déjà un peu le sujet, mais plutôt comme peu attirées par le cours. Dans certains cas, à l'issue de quelques leçons, certains éléments peu intéressés au départ se laissent absorber peu à peu par les diverses situations proposées. Quoi qu'il en soit, une relative homogénéité des temps se dégage et l'on peut considérer un temps 84 moyen de passage de l'ordre de vingt-cinq minutes. Il est vrai qu'au delà de trente minutes, une saturation assez forte intervient. En raisonnant au niveau du stage, les formés abordent l'EAO trois heures sur les dix-sept heures et demie. Cela représente approximativement 18% de leur temps de formation en 11 connaissance de l'entreprise". Quelquefois, certains binômes ayant terminé la leçon à visionner, la rappellent ou revoient un module sur lequel ils ont travaillé. Une telle pratique relève encore de l'exception. Bien que non mis en évidence, on peut penser que I'EAO contribue à une certaine diminution du temps d'apprentissage, puisque le corpus théorique est apporté en trois heures. Certes, la reformulalion par le formateur est toujours nécessaire, elle peut être réalisée alors sous différentes formes : cours magistral, exercice d'application, jeu ... Aux travers de nos observations directes et de l'enquête soumise aux formés, nous apprécions l'ensemble des effets qualitatifs sur les stagiaires. Dans le cas de cette formation, il ne faut pas envisager un suivi particulier très approfondi dans les progressions. Certes, une relation plus individuelle s'instaure entre intervenant et élève. Cependant, l'introduction du nouvel outil n'induit pas, dans ce cadre, une meilleure connaissance de chacun. Globalement, les groupes progressent quasi conjointement et les reprises de cours traditionnelles, à l'issue de chaque module, permettent une appréciation générale. 85 Ressentie un peu moins fortement que dans d'autres formations, elle se manifeste surtout par une plus forte implication personnelle. La passivité, face à un intervenant présentant son cours, laisse place à une activité canalisée. L'individualisation se note plus par une obligation d'action face à l'ordinateur, que par rapport à un suivi précis des acquisitions. L'apport essentiel pour ce public, recouvre une plus forte motivation d'apprendre, l'outil moderne qu'est l'ordinateur excitant une certaine curiosité. Dans ce cadre particulier, l'élément fondamental est en fait la participation active ; la vérification et la progression individuelle apparaissant secondaires. Bien évidemment, une relation enseignant/stagiaire s'instaure plus facilement et le dialogue devient plus simple. Cela représente une seconde forme d'individualisation dont il faut tenir compte. L'organisation des séquences d'EAO repose sur la constitution de binômes. Dans l'ensemble, cette structure semble plutôt convenir puisque 93 personnes la considèrent comme un avantage, 26 autres y trouvent plutôt un handicap. Cela ne surprend pas, car ces groupes sont constitués, très souvent, de stagiaires se marginalisant volontairement. Concernant le handicap au clavier, les réponses se présentent dans les mêmes proportions. En ce qui concerne 1' adaptation aux rythmes et connaissances propre à chaque formé, pour les 77 personnes sur les 123 interrogées, le cours se déroule à leur rythme ... Remarquons tout de même que ce nombre ne révèle pas une majorité écrasante. Selon le niveau scolaire initial, les appréciations des formés diffèrent. Les 28 stagiaires de niveau 11 correct" estiment que les informations leur parviennent trop vite alors que 18 seulement notent une excessive lenteur. Ces derniers sont de niveaux scolaires peu élevés. Ils se déclarent moins attirés par 86 des présentations délibérément simplifiées. Ceux qui trouvent une vitesse d'apprentissage trop grande approfondissent généralement beaucoup plus le cours. L'organisation de l'enseignement définit intrinsèquement des plages horaires. De ce fait, nous avons pu remarquer que des binômes plus lents, restant seuls en salle d'informatique pour terminer, accélèrent leur rythme pour compenser leur retard. Ils se sentent quelque peu remarqués par les autres et hésitent à déranger le cours. Il serait peut-être envisageable dans ce cas là de proposer une reprise du didacticiel en autoformation en dehors des créneaux de cours imposés. La découverte d'une possibilité de rappel de modules déjà visionnés attire quelque peu les jeunes. C'est ainsi, que, parfois, ayant terminé la leçon à examiner, ils revoient un module appréhendé le matin ou la veille. Cent quatorze stagiaires apprécient la très grande souplesse qu'apporte la formation assistée par ordinateur. Pour ce qui relève de l'adaptation aux connaissances de l'élève, les réponses sont partagées. Il est clair que le didacticiel ne développe pas un cursus particulier en fonction de tests préàlables. Cependant, les stagiaires notent une possibilité d'adaptation : ils avancent plus vite sur des questions déjà connues et, de ce fait, abordent plus rapidement les points nouveaux. En ce qui concerne l'interactivité, les foi"més, dans leur très grande majorité (104), se considèrent en dialogue permanent avec l'ordinateur et, par conséquent, très actifs pendant le cours. Les connaissances nouvelles leur semblent suffisamment reprises sans toutefois avoir le sentiment que leurs réponses influencent le déroulement du didacticiel. Une certaine conversation s'instaure entre la machine et les formés (78). La relative modestie de ce chiffre s'explique selon nous, par un excès de textes, peu apprécié par les jeunes. Un des principaux reproches apparus lors de nos conversations 87 avec les élèves, recouvre l'effet de lassitude face à une abondance d'écrits. Malgré leurs remarques à ce sujet, les apprenants apprécient, dans l'ensemble, la richesse du dialogue et les importantes sollicitations pour des interventions diverses. Cette implication directe, personnelle, apparaît fondamentale pour ce -type de public. 72% des personnes interrogées reconnaissent fournir une attention plus soutenue favorisée par les demandes de l'ordinateur. Globalement, ce dialogue avec la machine leur rend le cours plus attrayant (113 réponses), plus vivant (105), plus facile quant à l'effort à fournir (98). Les différents résultats montrent dans l' ensemble une implication plus forte des formés quant à l'apprentissage. Malgré la surabondance de textes, ils notent tout de même une activité soutenue face à l'acquisition des notions. Pour ce public, en grande majorité en rupture avec tout système d'enseignement, cela se révèle positif. De plus, la sensation de pénétrer un système économique et d'y apporter réflexions et influences représente une forte motivation. Ce n'est plus un contenu délivré in extenso mais un partage entre 1' apprenant et la machine. En ce qui concerne le degré d'acceptation du didacticiel et de l'EAO, comme que nous 1' avons énoncé plus haut, les stagiaires reprochent un excès de textes. La lecture tant au niveau déchiffrage que quantité à décripter demeure une question importante pour ce type de population. Notre évaluation a porté sur le didacticiel modifié mais non définitif. La version finale, mise en place depuis peu, a vu sa part de messages écrits considérablement diminuée. Dans l'ensemble, le cours se montre intéressant et attrayant avec bonne mise en relief des notions importantes. Plus généralement, les personnes sondées émettent des avis favorables sur l'EAO : outil très 88 intéressant (113), à développer (121) et très efficace pour apprendre (117). Une sensation d'étudier beaucoup plus rapidement se dégage de manière très forte (116 stagiaires). Ce constat apparalt fondamental lorsqu'il s'agit d'aborder des populations particulièrement marquées par le système scolaire. Il est parallèlement significatif de remarquer l'influence de l'EAO sur l'impression d'une plus courte durée de formation. Impliqués dans le processus, les élèves ne mesurent pas le temps. Une séance d'EAO leur parait toujours assez courte. 81 stagiaires ressentent une sensation d'avoir connu, par rapport au traditionnel, un stage plus court. De plus l'introduction de l'ordinateur semble enrichir les relations entre les formés et les rendre beaucoup plus importantes (88), plus faciles (98) et plus coopératives (91). L'ensemble des appréciations concernant ce nouvel outil 'se présentent de façon plutôt positive. Signalons, tout de même, que 16. stagiaires auraient préféré une formation traditionnelle. Certains jugent nécessaire d'apporter des améliorations, mais les annotations générales qu'ils font relèvent l'intérêt d'avoir travaillé sur l'ordinateur, pour eux "outil moderne et plein d'avenir". De fait, l'utilisation d'outils informatiques en tant que tels amorce un premier contact avec les nouvelles technologies. Cette familiarisation timide apporte un "plus" face aux objectifs atteints puisque, de plus en plus, les postes de travail intègrent l'ordinateur. 2..U Effets sur le formateur · Pour l'approche quantitative relative au formateur, l'EAO n'induit aucun effet. Son temps d'intervention reste absolument 89 identique puisqu'il demeure à la fois en salle de cours et en informatique. Pendant que les formés abordent le didacticiel, il est présent, répond aux questions et ne s'absente jamais. Comme pour les autres cadres d'évaluation, nous appuyons nos propos sur les enquêtes soumises aux formateurs et aux formés. Dans le cas présent, deux personnes assurent ces stages, ce qui amènera parfois des idées différentes pour une même question posée. Place du fonnateur : (dimension pratique) La place du formateur reste, sans conteste, très forte. Alors qu'un des enseignants n'en mesure pas un amoindrissement, 1 'autre perçoit, peut-être indirectement, une diminution de ses prérogatives. Selon lui, son intervention se limite à la phase d'introduction et de reformalisation des concepts. Il doit donc partager la diffusion des connaissances avec l'ordinateur. Bien que demeurant en pratique le centre du groupe, la transmission cognitive se partage ... , le formateur n'apparaissant plus comme le seul détenteur du savoir. Les deux enseignants ressentent, pour leur part, une transformation de leur relation avec les stagiaires. Les échanges particuliers deviennent plus riches, plus nombreux et, dans certains cas, s'instaure un véritable cours particulier. La place du formateur, tout en restant aussi importante, glisse d'une relation collective vers un rapport individuel ayant pour référent l'EAO. Quoi qu'il en soit, l'objectif général repose sur le développement de la complémentarité EAO/animateur. En l'état actuel de développement de l'EAO dans cette formation : il ne parait pas envisageable de voir diminuer la place de l'animateur au bénéfice d'une utilisation "libre service absolu". 90 Rôle du formateur : (dimension pédagogique) Pour l'un des deux formateurs, l'aisance d'emploi de l'ordinateur ne se révéla pas immédiate. Un sentiment de perte de contrôle du cours et de disparition derrière la machine apparut. Peu à peu, une accoutumance s'instaura, et aboutit à une plus grande sécurité face au cours. L'élément premier de diffusion de la connaissance étant l'EAO, chacun retrouve une modification de son rôle. L'intervention de 1' animateur prend corps à partir du contenu du didacticiel. C'est alors que l'un des formateurs se sent plus "conseil 11 que professeur. La tâche n'en demeure pas plus facile, puisqu'il s'agit d'apporter un complément à ce qui a été appréhendé. La partie traditionnelle relève tout d'abord de la synthèse du module visionné. Les stagiaires insistent beaucoup sur l'importance de ces mises en commun, car il leur est très souvent difficile de synthétiser ce qui vient de se dérouler sous leurs yeux. Au-delà de l'individualisation lors du travail devant les consoles, l'animateur régule son apport de cours en fonction du groupe : vécu de chacun ... Il reformule en quelque sorte les points clés du didacticiel, en approfondit certains et personnalise la formation en fonction des cas particuliers. Un nouveau 11 style" d'animation de groupe s'instaure : soit directement lors des séances EAO, soit indirectement lors des reprises traditionnelles. Tout d'abord, le découpage des séquences avec changements de salles modifie considérablement l'attitude des stagiaires en situation pédagogique. 11Le cours magistral" s'amenuise en temps et en contenu, puisque, le plus souvent, l'animateur utilise les interventions des élèves, et leurs questions sur ce qu'ils viennent de visionner. Cependant, bien que différentes, ces séquences de reprises de notions restent encore "lourdes" pour certains, et dénuées de toute activité individuelle. L'implication 91 constante, et active représente le maître-mot de toute pédagogie afférente à ce type de public. Certes, les jeunes sollicitent eux-mêmes ces moments de synthèses, mais un juste équilibre se doit d'être trouvé. L'introduction de l'EAO redéfmit le rôle pédagogique de l'enseignant et l'incite à mener plus loin encore toute idée d'implication, et d'action effective pour chacun. Rigueur pédagogique demandée au formateur dans la conception et la réalisation de la formation : L'introduction de l'EAO nécessite effectivement une certaine rigueur sur le découpage de la journée. L'alternance EAO/reprise collective instaure un cadre d'évolution du stage. La formation traditionnelle laisse souvent, pour ce type d'enseignement, une place importante à la "dérive" et donc à la spontanéité. Une question fondamentale surgit alors : Doit-on imposer un programme établi ou 11Satisfaire" les stagiaires par rapport à ce qu'ils recherchent ? Un partage équitable doit s'opérer. Bien que l'apport cognitif ne représente pas l'essentiel du stage, beaucoup d'informations, et d'explications sont à diffuser et à manipuler. L'EAO permet de répondre à cette double exigence. Une structure rigide en soi et comportant l'ensemble des connaissances à diffuser, pénètre le stage; elle en forme l'archétype. Le formateur traite alors tous les ·sujets, même si certains lui paraissent moins faciles ou moins fondamentaux. Il s'appuie donc sur le didacticiel, et alimente ses interventions en fonction de celui-ci. Le cours autrefois assez souple trouve par là même une structure ; l'initiative pédagogique n'appartient plus essentiellement à 1' enseignant 92 mais repose en grande partie, pour son contenu, sur l'auxiliaire didactique. 2.3.3 Effets sur le système de formation · L'introduction de l'EAO n'induit aucun effet quantitatif majeur sur le système de formation. La durée d'une session demeure la même (2 jours et demi). Le nombre de formés reste quasi identique. A ce niveau, en l'état actuel de fonctionnement, l'EAO impose même une limitation dans les groupes puisqu'au delà de 16 stagiaires, les binômes deviennent des équipes de trois. Quelques cas de travaux à trois ont montré les limites d'une telle utilisation, chacun ne pouvant approcher convenablement 1' ordinateur. Conscients des difficultés encore réelles des synthèses traditionnelles, les responsables vont introduire un jeu. Il faut impliquer d'une autre façon les formés, et leur permettre de réinvestir les connaissances préalablement reçues. L'objectif sera alors de gagner du temps sur les révisions et apprentissages (EAO et reprises collectives) pour parvenir assez vite au jeu. Ce dernier, en cours de création, complètera donc la formation et, combiné avec l'EAO, conduira à un plus grand approfondissement des connaissances. La structure générale du stage reposerait alors sur l'alternance EAO/synthèse collective rapide et se terminerait par le jeu. L'idée d'une mise à disposition de l'EAO pour réviser une nouvelle fois certaines notions serait envisageable. Un des effets qualitatifs principaux de la mise en oeuvre de l'EAO relève de l'homogénéisation du contenu entre animateurs. Ce 93 véritable cadre apporté au sein du cours donne une ligne directrice forte. D'ores et déjà, la formation est mieux appréhendée. Avant l'introduction de cette "charpente" il fallait noter une grande hétérogénéité dans les cours, le formateur s'adaptant à son public. Par là-même, les responsables du système de formation possèdent une plus grande maîtrise du discours tenu durant ce stage. Le message à délivrer apparaît mieux cerné, puisque la base de travail s'appuie sur un support pédagogique fort. Cet effet, au niveau de toutes les sessions organisées, forme "un plus 11 fondamental apporté par l'EAO. Par ailleurs, le particularisme de ces formations rend très difficile la mise à disposition d'animateurs expérimentés. Sans intervenir sur le coû.t, la mise en oeuvre de cet outil peut permettre aux responsables du centre de formation de recruter plus facilement des formateurs pour ce type d'enseignement. L'introduction de l'EAO apportant le corpus théorique, et livrant assez de souplesse pour adjoindre d'autres outils pédagogiques, la tâche de l'enseignant se trouve allégée. Cela lui permet alors de se consacrer plus précisément aux problèmes relationnels, point clé pour une meilleure réussite du stage. 2.4 Rapport coût-efficacité de l'EAO mis en oeuvre en "Connaissance de l'entreprise" : Ainsi que nous avons pu le mettre en lumière tout au long de l'évaluation, la spécificité du public ciblé pose le problème coût-efficacité en termes particuliers. Ces jeunes en échec scolaire et quelquefois professionnel ne désirent plus emprunter les chemins de la formation. Les enseignements traditionnels jusqu'alors reçus n'ont pu agir en ce sens. Il fallait donc améliorer le stage. Cela passe inévitablement par la multiplication des outils pédagogiques, l'EAO en était 94 un parmi d'autres. Comme le rappellent très souvent les responsables du centre et les enseignants, la part importante relève plutôt de la forme, de l'état d'esprit, du comportement. Mais l'acquisition d'un fond cognitif reste un objectif prioritaire mais pour une meilleure intégration dans l'entreprise. Partant de l'idée d'améliorer la formation, l'introduction d'outils modernes, motivants, valorisants, s'impose. Cette intégration d'auxiliaires pédagogiques supplémentaires justifie-t-elle le surcoût engendré:·? Dans ce cas, l'optimisation du rapport coût-efficacité signifie 1' obtention d'effets ayant au moins la même ampleur que le surcoût. Tout d'abord, il semble opportun de rappeler le coût heure/stagiaire pour chacune des deux formations. Formation traditionnelle Formation mixte Coftt horaire ensei- 28 F 50 F gnementlstagiaire Ces chiffres montrent un surcoût représentant 78,5% du coût de formation traditionnelle. Cette hausse importante s'explique par l'absence de gains en termes de durée de formation et du nombre de stagiaires formés. Dans cette perspective, le surcoût peut effectivement sejustifier par une meilleure qualité de formation (voir synoptique en fin de chapitre). Il permet alors de mieux réaliser ce qui apparaissait très difficile auparavant. En l'état actuel, la conclusion ne semble pas très favorable (coût plus élevé).

Ces personnes, toutes volontaires, viennent, pendant trois années successives, suivre un trimestre d'enseignement spécifique (90 heures) : économie/gestion, mécanique/automatismes, électricité/électronique. Pour la partie 11 Economie-gestion", et plus particulièrement pour le module "l'entreprise et sa comptabilité", le didacticiel ARDEMI, 11Les mécanismes de base de la comptabilité\ se trouve intégré. L'évaluation menée se situe donc précisément dans ce contexte. 6.1 Introduction de l'EAO en formation "Mécanismes de base de la comptabilité" : Objectifs de la formation : - Se forger une représentation de l'entreprise au travers de la comptabilité ; se construire une image plus claire de l'activité de l'entreprise. -S'initier à une lecture de comptes, être capable de lire un bilan et un compte de résultats. - Passer des écritures simples sans exigence professionnelle. 160 - Susciter chez les personnes un intérêt et les motiver afin de connaître plus en ce domaine. Que ce cOurs soit réalisé traditionnellement ou par EAO, les objectifs restent identiques. Forme d'intégration de l'EAO : Prenant en compte la typologie des formes d'intégration de l'EAO telle que définie par nos soins, il s'agit d'appliquer cette grille au cas évalué : But apporte une formation nouvelle à l'apprenant Contexte intègre la formation existante Lieu dans le centre de formation Nombre de micro-ordinateurs une salle de type "laboratoire" : 2 appareils Moment pendant le temps de formation Manière libre accès total Public très captif Unité de base individuelle/en binôme Nature apprentissage Intégration substitution totale Relation au formateur avec alternance 161 Mise en oeuvre de 1' évaluation : Notre intervention repose sur divers entretiens avec le professeur responsable de la formation (et concepteur du didacticiel) et sur notre présence en fin de module. Pour chacune des deux sessions évaluées, un tirage au sort de quatre personnes a été réalisé. Ce sont donc quatre Stagiaires qui travaillent en autoformation complète sur EAO. Les autres suivent le cours dispensé de manière traditionnelle par l'enseignant. Au-delà de l'intervention magistrale, le professeur intègre transparents, diapositives et surtout le jeu 11 ldeco, un nouvel outil pour découvrir la comptabilité 11 • 6.2 Etude comparative d'une formation traditionnelle puis avec EAO : "L'entreprise et sa comptabilité" : Cadrage méthodologique et hypothèses retenues · Ne pouvant connaître le montant des charges diverses (bâtiments, électricité, assurances ... ) afférentes aux formations dispensées, nous ne pouvons fournir qu'un coût partiel de la formation. Par ailleurs, la prise en compte des frais de déplacements et des salaires ne peut s'opérer puisque, là encore, aucun chiffre n'a pu être fourni. Mais l'absence de ces deux derniers types de données ne doit pas, pour la comparaison, modifier les conclusions puisque frais et salaires demeurent dans les deux cas, identiques. Par contre, l'évaluation de la durée d'utilisation annuelle des micro-ordinateurs et surtout du didacticiel apparaît plus aléatoire. 162 Nous avons retenu, pour les premiers une base de 37 semaines pendant l'année, tenant compte des trèves de congés scolaires. Pour le second, nous prenons en compte le temps réel de mise en oeuvre du logiciel pendant l'année. En fait, vingt-quatre personnes d'une autre classe du Centre (Préparatoire CAPET) et douze stagiaires de la formation continue l'ont utilisé. Il est clair que toute évaluation du temps réel de pratique sur le dida~ticiel _est impossible, d'autres usagers pouvant très bien venir travailler en dehors des cadres prévus. A noter que nous retenons pour le coüt du didacticiel son prix de vente hors taxe (Franklin Partners). En effet, il s'avère difficile d'évaluer le coüt ARDEMI pour l'Education Nationale et surtout d'établir la part afférente au Centre de Formation des Maîtres de Châlon sur Saône par rapport aux autres usagers de l'Education Nationale. Le Centre posSède un didacticiel installé sur deux micro-ordinateurs (procédure ARDEMI). Pour les durées d'amortissement, nous maintenons le choix établi auparavant : micro-ordinateurs et matériels connexes: 4 ans - didacticiels : 3 ans.

Les moyennes sur 20 obtenues en pré et post tests figurent dans les tableaux ci-dessous : MATIERE OUTIL TEST 1 TEST2 ECART L'entreprise et sa comptabilité traditionnel 9,62 12,69 + 3,07 (20 stagiaires) L'entreprise et sa comptabilité EAO 8,27 12,68 + 4,41 (8 stagiaires) La lecture de ce tableau montre des acquisitions dans les deux cas. La moyenne de départ des personnes travaillant en EAO étant plus basse, un phénomène de "rattrapage" se réalise. En effet, les scores de fin de session atteignent le même niveau. Par rapport au public visé, il semble que l'EAO rende possible, pour ce contexte de mise en oeuvre de l'outil, de meilleures acquisitions cognitives. Temps d'apprentissage : Pour la session traditionnelle, la durée de l'intervention professorale s'élève à huit heures. En autoformation, les temps de travail 165 varient entre trois heures quarante cinq et sept heures quarante cinq réparties, bien évidemment, en plusieurs plages d'étude. En tout état de cause, il est à noter une baisse certaine du temps d'apprentissage par EAO. Même les personnes 11 les moins rapides" n'atteignentjamais les huit heures nécessaires en traditionnel. Une réduction du temps d'apprentissage s'avère donc réelle. Du point de vue qualitatif, exceptées deux personnes percevant un déroulement trop rapide du cours, l'ensemble des personnes interrogées considèrent une adaptation convenable au rythme de travail. Les différentes questions relevant de l'interactivité livrent des réponses convergentes. Le dialogue avec l'ordinateur s'avère permanent, la machine faisant réagir très souvent l'apprenant. Une conversation s'instaure, les échanges se présentent assez riches, une sensation d'intervention constante se dégage. Les appréciations relatives au didacticiel paraissent plutôt positives. Cependant, les explications données se montrent, pour six personnes, plutôt difficiles et quelque peu insuffisantes. Il faut noter, corrélativement, une impression de passer beaucoup de temps à réfléchir à la solution (7 réponses), à comprendre les questions (6 réponses). En fait, ces enseignants considérent surtout l'EAO comme un support et non comme un substitut au pédagogue. Une liaison entre le professeur et l'apprenant doit, selon eux, demeurer (explications, 166 compléments d'informations, ... ou EAO complément du cours). D'une façon générale, l'ensemble des personnes interrogées reconnaissent, sans excès, des atouts indéniables à ce nouvel outil. .. tout en émettant une certaine réserve sur 1 'utilisation en auto formation telle que vécue. Effets sur le formateur : Dans le cas présent d'une pratique de l'autoformation pure, l'enseignant disparaît totalement. Son temps d'intervention devient nul. Le formateur ne trouvant aucune place, aucun rôle sous cette forme d'utilisation de l'EAO, aucune évaluation qualitative n'est réalisable. Malgré tout, le professeur responsable de cette formation, concepteur du didacticiel utilisé, a dû mener une réflexion pédagogique approfondie lors de son élaboration. D'après ses indications, cela a induit une reprise de son cours traditionnel réinvestissant en quelque sorte la démarche structurée du didacticiel. Effets sur le système de formation : L'évaluation comparative autoformation/cours traditionnel telle que réalisée dans cette étude ne correspond pas entièrement aux perspectives d'utilisation futures. L'EAO se présenterait essentiellement en complément de l'enseignement magistral. Prenant en compte cette optique à venir, aucun effet quantitatif sur le système de formation n'apparaît envisageable. L'apport qualitatif essentiel recouvrira la mise à disposition sans condition de l '-EAO à toute heure de la journée en vue d'un travail individuel. Il s'agira avant tout d'un 167 complément du cours (résumé, reprise et réinvestissement des notions) ou d'un soutien pédagogique. 6.4 Rapport coût-efficacité de l'EAO mis en oeuvre au Centre de Formation des Maîtres de Chalon sur Saône : Ainsi que nous avons pu le constater, nous disposons, pour cette étude de cas, de coûts partiels. Seul est pris en compte l'acte d'enseignement ; de plus, le coût de formation par EAO repose sur des hypothèses très subjectives. L'égalité apparente du cotît heure par stagiaire pour chacun des deux modes (15 F) laisse montrer que les coûts de l'EAO sans formateur n'atteignent pas des niveaux dispendieux. Une utilisation du didacticiel sur un nombre plus conséquent de stagiaires devrait aboutir à un coût horaire par EAO bien moindre. Cette égalité apparente des coûts résulte, pour l'heure, du faible nombre de stagiaires utilisant l'EAO. Le développement futur sur une population plus nombreuse devrait, sans conteste, abaisser notoirement les coüts. Par ailleurs, quelques éléments relatifs à l'efficacité apparaissent évidents : meilleures acquisitions cognitives, temps d'apprentissage réduit, disponibilité permanente des cours (voir synoptiques en fin de chapitre). Il semble donc qu'une amélioration des deux termes du rapport coût-efficacité soit, dans ce contexte possible. Dans le cas spécifique que nous venons d'évoquer, le public ciblé diffère notablement. Ce cadre d'étude apporte néanmoins des enseignements significatifs. Il ne peut que conforter l'idée fondamen- 168 tale "d'apprendre à apprendre 11 si utile pour des popuhitions peu tournées vers la formation. 169 CENTRE DE FORMATION DES MAITRES DE CHALON SUR SAONE Tableau synoptique des effets de I'EAO par rapport à une formation traditionnelle "L'entreprise et sa comptabilité" ··· .• ···· .. ••.•• ... ·.·•· .. ·... .. · ...• ···.·· .EF~J'}!8,§URLE~ FORMES • .. •Ï••+>.·•fi.i.s Evaluation quantitative Meilleures acquisitions cognitives Réduction du temps d'apprentissage Evaluation qualitative Individualisation de l'apprentissage : travail à son propre rythme Interactivité : dialogue permanent avec la machine Evaluation quantitative Temps d'intervention nul Evaluation qualitative Evaluation quantitative Evaluation qualitative Disponibilité totale des cours à toute heure de la journée '·· Chapitre 7 Evaluations qualitatives de l'introduction de l'EAO aux Gaz de France (GDF) et Electricité de France (EDF) --------~------------------~~~ 173 N'ayant pu mener à bien des évaluations du type de celles développées ci-avant, il nous est, par contre, possible d'apporter quelqués réflexions qualitatives sur l'intégration de ce nouvel Outil dans ces deux institutions. La présentation n'en apparaît pas moins intéressante puisqu'elle· permet d'enrichir particulièrement l'analyse des effets de l'EAO dans des cadres particuliers. Les enseignements diffusés recouvrent des matières spécifiques, techniques non développés sur d'autres 11 terrains 11 • 7.1 Evaluation au Gaz de France (GDF) : La Société Auxiliaire de l'Industrie Gazière (SAIG), filiale du groupe GDF, produit depuis quelques années des modules d'Enseignement Assisté par Ordinateur. Confronté à deux problèmes majeurs liés à la diffusion des connaissances gazières - nombre limité de formateurs, coüt de déplacement de nombreux agents vers des centres de formation - GDF commence à développer l'utilisation de l'EAO sur différents sites. Introduction de 1 'EAO en diverses formations : Divers didacticiels accompagnés parfois de simulateurs ont été mis en oeuvre : 174 - Calcul informatisé des réseaux de distribution de gaz : ETRE-CESAR. - Réponse aux appels de tiers signalant une odeur de gaz et première intervention : PIRATE-S NIF. - Remblayage, compactage des tranchées. Prenant en compte la typologie des formes d'intégration de l'EAO telle que définie par nos soins, il s'agit d'appliquer cette grille au cas évalué : But apporte une formation nouvelle à l'lapprenant Contexte intègre la formation existante/répond à un énorme problème de formation difficile à résoudre par des enseignements traditionnels Lieu local très proche du lieu de travail/centre de formation Nombre de micro-ordinateurs souvent un seul, parfois plusieurs (cela dépend des sites) Moment pendant le temps de travail Manière libre accès contrôlé/intégré Public captif Unité de base individuelle Nature apprentissage Intégration substitution totale/mixte Relation au formateur avec suivi 175 7 1 2 Etude des effets de la mise en oeuvre de l'EAO · Après un entretien avec le directeur de la SAIG à Paris puis avec le responsable EAO/GDF à Lyon (chargé de développer le nouvel outil sur ce site), il a été procédé à un envoi de notre enquête à différents centres GDF de France. Quarante-cinq personnes ont été interrogées ; la répartition par didacticiel se présente de la manière suivante: ETRE (16), PIRATE (18), SNIF (4), COMPACTAGE (7), soit un total de 45 personnes. 7.1.2.1 Effets sur les formés: Corroborant les répons~s aux questions proposées dans l'enquêtet les commentaires libres écrits laissent dégager des points fondamentaux liés à l'efficacité de l'EAO sur les formés. Ils relèvent essentiellement de l'individualisation très forte de l'apprentissage encore bien plus nécessaire sur des matières techniques, spécifiques telles que celles enseignées. Cet apport sans cesse mis en lumière recouvre les points suivants : . . travail à son propre rythme . formation souple (reprises possibles au début ou simple retour arrière limité), modulable en fonction de ses disponibilités, adaptable à ses besoins . Implication forte et très grande activité au niveau de l'apprentissage . Réflexion personnelle importante, peu de dérivation hors sujet 176 . Absence de censure de ses réponses, moindre appréhension face à une réponse à livrer (problème de timidité). Chacun reconnaît en cet outil une possibilité de travail personnel important et approfondi, source d'un meilleur apprentissage. 7 .1.2.2 Effets sur le formateur : Sur les quarante-cinq personnes interrogées, vingt-neuf ont suivi les didacticiels avec un formateur, les autres ayant travaillé seuls. Bien que la manière de mettre en oeuvre ce nouvel outil soit laissée au choix des différentes unités, il semble que le libre accès contrôlé retienne souvent l'attention des responsables. Notons cependant la possibilité pour certains formateurs d'intégrer cet outil dans leur propre cours. Si l'on garde l'idée d'une intégration sous forme de libre-service contrôlé, le rôle et la place du formateur disparaissent. Le complément pédagogique relève alors d'une personne pouvant intervenir à la demande de l'apprenant. Un ou deux cadres (ou agents de maîtrise) assurent, conjointement à leur tâche habituelle, les apports complémentaires. Cela conduit à formuler l'hypothèse d'une baisse importante des coûts, un formateur désigné n'intervenant pas. Certes, les personnes "ressources" voient le temps réservé à la tâche normale diminuer mais, en tout état de cause, leur intervention auprès des apprenants ne peut qu'être assez partielle. L'idée fondamentale ressortant de ces quelques propos repose sur l'utilité de la présence d'un "homme ressource" dès lors que les stagiaires abordent seuls un didacticiel. 177 7 .1.2.3 Effets sur le système de formation : Nos différents entretiens avec des responsables GDF et SA!G, ainsi que la lecture de quelques rapports internes établis suite à des expérimentations partielles laissent dégager quelques effets sur le système de formation. Tout d'abord, il est à souligner l'intérêt de la mise en place de mêmes didacticiels sur l'ensemble du territoire. En effet, cela permet une homogénéisation des connaissances diffusées et une tendance à uniformiser certaines pratiques. De plus, l'apport d'un "corpus théorique" stable limite la difficulté d'engager ou de former des enseig·nants spécialistes en ces domaines. La possibilité du recours à des personnels locaux essentiellement voués à un complément d'informations apparaît non négligeable. Corrélativement, la hiérarchie immédiate peut, à tout moment, connaître les éléments de connaissances apportés à ses subordonnés. La relative souplesse de l'EAO contribue, par ailleurs, en une réduction notoire de la 11 gêne 11 liée à l'absence d'une personne (moindre déplacement- souplesse dans la réalisation de la formation : possibilité de reporter sans difficulté une plage horaire en cas d'absolue nécessité de mise à disposition opérationnelle d'un formé, moindre nécessité de prévoir bien à l'avance i'envoi en stage d'une personne ... ). Tout cela devrait permettre une massification importante de la formation, le recours à dès sessions traditionnelles s'avérant, pour un nombre important de personnes à former, impossible. 178 7.2 Evaluation au Centre de Production Nucléaire EDF du Bugey: Le Centre de Production Nucléaire du Bugey (CPN du Bugey) ayant introduit l'EAO depuis 1982, un recul temporel plus large en ce domaine rend l'étude de première importance. Certes, ce cadre a été plusieurs fois retenu pour des investigations liées à l'intrOduction de cette nouvelle technologie ; ·néanmoins, il forme, pour notre recherche, un cas tout à fait significatif permettant d'apporter à notre réflexion des éléments dignes d'intérêt. En effet, l'utilisation de l'EAO n'étant jamais parvenue au niveau prévu et voyant- même, depuis ces dernières années, sa fréquentation baisser, il conviènt de s 'inter'roger. 1.Ll Introduction de 1 'EAO au CPN du Bugey : L'objectif général, quel que soit le thème traité, relève du maintien des connaissances. Les formations dispensées par EAO demeurent essentiellement techniques et très spécifiques au système nucléaire. Elles se rajoutent à celles intégrées dans le cycle de travail (six semaines dont une de formation) et stages. Il ne s'agit absolument pas du passage sur simulateur de conduite de Centrale mais d'étude sur didacticiel avec très grande variété des thèmes abordés. Prenant en compte la typologie des formes d'intégration de l'EAO telle que définie par nos soins, il s'agit d'appliquer cette grille au cas évalué. A noter que les terminaux sur lesquels travaillent les 179 apprenants sont reliés par lignes PTT à un ordinateur central situé à Clamart. But qualifier/mettre à jour les connaissances Contexte massification de la formation Lieu dans une salle près du lieu de travail Nombre de micro-ordinateurs un micro-ordinateur Moment pendant le temps de travail Manière libre accès total non supervisé Public public captif 1 Unité de base individuelle Nature complément de formation Intégration substitution totale Relation au formateur non conduit L'évaluation repose sur divers entretiens avec un Ingénieur Sûreté Radio Protection (!SR) qui a été chargé d'adapter l'EAO au CPN Bugey. Notre enquête habituelle a été soumise à soixante personnes de la Centrale travaillant essentiellement en salle de commandes et contrôles. Effets et limites de la mise en oeuvre de l'EAO: Effets qualitatifs de la mise en oeuvre de l'EAO : La mise en oeuvre de 1 'EAO en libre accès non supervisé nous a fait interroger des personnes motivées quant à l'utilisation de l'outil (incitation individuelle, promotionnelle). 180 D'un point de vue pratique, ordinateur et didacticiels fonctionnent "assez bien". La mise en route paraît un peu. compliquée. En ce qui concerne l'interactivité, le dialogue avec l'ordinateur semble limité. A de nombreuses reprises, des personnes mentionnent la difficulté de connexion et d'accès au didacticiel désiré. De plus, certaines soulèvent le problème de la rigidité de cet EAO et du manque d'analyse de réponse (blocage de la leçon pour un mot clé difficile à trouver). Malgré cela, beaucoup d'apprenants notent la diversité des sujets abordés et l'intérêt de cette nouvelle technique comme support de formation (complément à un stage, à une formation ... ) ou outil de révision. Un dernier point fort souvent mis en exergue recouvre la disponibilité totale des cours y compris la nuit. Beaucoup soulignent leur préférence pour un travail sur EAO, la nuit ... se sentant moins motivés pour une étude sur livre ou document en cette période de la journée. Pour le formateur, l'ensemble des personnes ne ressentent pas une nécessité absolue de sa présence. Il est sûr que chacun des membres de l'équipe de quart peut recourir, pour explications ou compléments d'informations, à un autre membre du groupe. Le supérieur immédiat, voire même le chef de quart remplissent cette fonction. Ainsi que nous l'avons abordé en début d'étude, l'EAO ne connait pas un taux de fréquentation aussi élevé que prévu. Il est opportun, après ces présentations, de réfléchir sur les conditions expliquant cet intérêt modéré pour le nouvel outil. 181 Limites d'utilisation de l'EAO: Si l'utilisation de l'EAO par GDF connaît un certain succès (voir synoptique en fin de chapitre), en revanche les applications qui en sont faites à EDF montrent quelques limites de cette intégration des NTI. Bien que n'ayant pas atteint un taux de fréquentation maximal, l'EAO s'est vu utilisé plus abondamment lorsqu'une partie de la préparation d'épreuves pour une promotion interne a été mise en place. Il est certain qu'un recours à l'EAO repose, dans ce cadre, sur une motivation intéressée. Dans une équipe de quart, chacun peut trouver un moment pour se former et donc travailler sur EAO. Ce sont bien souvent les personnes les plus accoutumées au travail personnel qui abordent les didacticiels. Les indications fournies montrent, du point de vue du niveau scolaire des apprenants, une fréquentation habituelle des personnes de niveau DUT/BTS et au-delà. Celles de niveau CAP/BEP se sentent relativement moins concernées par cet enseignement... bien que des cours adaptés à leur niveau soient proposés dans la palette. La dimension 11 culture personnelle 11 autonome, rendue possible par ce nouvel outil, ne peut se développer. Une incitation profonde des personnes est, par conséquent, nécessaire. Cette réticence face à l'utilisation de l'outil repose, en fait, sur trois facteurs déterminants. Le premier, à caractère technique, provient de l'EAO lui-même : connexion au réseau, qualité des didacticiels. Les deux autres, liés à la mise en oeuvre de l'outil appartiennent à la motivation des formés et corrélativement à l'attitude de la hiérarchie. D'une manière plus générale, une nouvelle fois se confirme cette nécessité, pour les années futures "d'apprendre à apprendre". Face à cette première phase d'implantation de l'EAO montrant quelques difficultés et limites, le Service de la Production Thermique 182 met en place depuis 1988 un nouveau plan d'action EAO. Ce dernier vise, en particulier, de par une restructuration complète des matériels, à améliorer l'image de l'EAO et à en développer l'utilisation dans des formations centralisées et décentralisées (avec implication de la hiérarchie). Par ailleurs, le projet P9 relatif à l'informatique dans la formation mène une réflexion plus large en ce domaine et entend donner une impulsion supplémentaire à 1 'intégration de ce nouvel outil. 183 GAZ DE FRANCE Tableau synoptique des effets de l'EAO par rapport à une formation traditionnelle "Techniques gazières" (I) Evaluation quantitative Individualisation très forte de l'apprentissage : travail à son propre rythme, implication personnelle forte Autonomie dans le travail : retour arrière, reprises personnelles Interactivité : dialogue permanent avec la machine Réflexion personnelle importante Formation souple, modulable en fonction de ses disponibilités, adaptable à ses besoins Absence de censure de ses réponses, moindre appréhension face à une réponse à livrer Evaluation qualitative Disparition du rôle et de la place du formateur en tant que tel/Rôle et place pouvant être tenus par des supérieurs hiérarchiques Compléments pédagogiques, apports complémentaires Evaluation qualitative Homogénéisation du contenu des formations et ..des connaissances diffusées Limitation des difficultés d'engager ou de former des enseignants spécialistes Plus grande souplesse pour réaliser les formations ; moindre gêne liée à l'absence d'une personne E.ffit futur : Massification importante de la formation Conclusion 187 Tout au long de cette étude, nous avons tenté, face à l'approche collt-efficacité de l'EAO pour la formation en cours d'emploi, de réaliser un travail le plus large possible. Saisir toutes les dimensions du problème ne fut pas toujours facile. Sachons surtout que Ie"terrain" sur lequel nous avons oeuvré se présente comme fort mouvant et en constante mutation. Il était cependa~t clair qu'une base de réflexion se devait d'être engagée et qu'il fallait examiner, un peu plus profondément, ce "bouillonnement". Notre action_ s'est donc placée à ce niveau. Afin de bien cadrer l'ensemble des enseignements à dégager, il est intéressant de dresser une typologie des modes d'utilisation positifs ou négatifs de l'EAO face aux "terrains" examinés. Par ailleurs, il convient de réaliser, par rapport aux travaux engagés, une synthèse spécifique des dimensions abordéeS : répercussions sur les coûts, efficacité de l'EAO (aspects positifs et négatifs), évolution du rapport coût-efficacité. TYPOLOGIE DES MODES D'UTILISATION POSITIFS OU NEGATIFS DE L'EAO A partir de l'échantillon examiné, il est possible de déterminer certaines utilisations de l'EAO fonctionnant efficacement. * "Formation mixte 11 (EAO et intervention du forl1).ateur) à contenu technique - public de bas et moyen niveaux. * "Formation mixte" à contenu général (français-mathématique) public de bas niveau volontaire. 188 * "Formation mixte" à contenu général (initiation économique) - public de très bas niveau non demandeur - Caractère moderne, motivant, valorisant de l'outil. * "Autoformation" à contenu technique (initiation comptable)- public de bon niveau. * -"Autoformation11 en libre-accès contrôlé (homme ressource) et supervisé (suivi assuré par le supérieur hiérarchique ou une autre personne)" à contenu technique - public de bas et moyen niveaux. * ~~ Autoformation" en libre-accès à contenu technique diplômant ou qualifiant - public de bas et moyen niveaux. A 1 'inverse, les études de cas laissent apparaître certaines utilisations non efficaces. * "Autoformation 11 libre-accès tout contenu - public de bas ·niveau. Il faut noter que plus les niveaux sont bas, plus la désaffection pour la formation volontaire est grande (sauf si la motivation est intéressée). * "Autoformation" à contenu technique- public bas niveau. Pour l'heure, deux enseignements généraux sont à retenir de ces évaluations : Le mode de ''formation mixte" apporte des effets largement positifs et en particulier avec les populations en difficultés. Secondement, l'autoformation pose des problèmes qui vont croissant avec l'abaissement des niveaux. 189 Corrélativement, la mise à disposition de cours en libre-accès ne bénéficie qu'aux personnes possédant déjà une relative autonomie d'apprentissage. REPERCUSSIONS SUR LES COUTS En premier lieu, avant toute comparaison de coûts, il cOrivient de bien rappeler l'indicateur de coût utilisé. Comme nous avons pu le constater dans le cas de chez.RVI, le choix de tel ou tel indice conduit - à des conclusions différentes : coû.t horaire par stagiaire, coût du stage (à effectif égal). Si l'on regarde le coüt global du stage chez RVI, l'introduction de l'EAO induit une baisse du coût. Globalement, les gains en termes de jours de stage sont plus importants que les coüts supplémentaires liés aux matériels e( didacticiels utilisés. Par contre, le coüt horaire par, stagiaire est plus élevé en formation mixte ; cependant, ce surcoût ne se révèle absolument pas dispendieux. A quelques rares exceptions près (CEPC), la hausse du coût horaire par apprenant est modérée. Une analyse plus approfondie de la situation actuelle et des perspectives de développement de l'EAO, montre que l'on peut s'attendre, en toute logique, à une baisse des coûts horaires. Deux facteurs importants peuvent intervenir dans la baisse des coûts : une moindre intervention du fonnateur et une réduction du temps de formation (Session plus courte suite à un gain de temps d'apprentissage). 190 EFFICACITE DE L'EAO Tout au long de notre étude, nous avons été amenés à mettre en évidence les effets quantitatifs et qualitatifs liés à J'introduction de l'EAO. L'objet de notre présent propos sera de les rappeler brièvement puis, dans un second temps de livrer quelques réflexions sur les limites de l'efficacité de ce nouvel outil. Récapitulation des effets liés à l'introduction d.e I'EAO : Les études strictement comparatives enseignement traditionnel- /autoformation par EAO, certes difficiles à mettre en oeuvre, laissent apparaître : un niveau égal d'acquisitions cognitives pour un temps d'apprentissage moindre lorsqu 'on utilise les nouvelles technologies. Ces effets ne sont possibles qu'à condition que les personnes sachent être autonomes dans le travail sur didacticiel. En "mode mixte" (formateur + EAO), de meilleurs résultats sont obtenus. Ils se traduisent par une baisse du temps d'apprentissage ayant des répercussions sur le nombre d'exercices réalises et sur la durée de la session, une meilleure motivation des formés, une individualisation et personnalisation de la formation, ainsi que par l'apprentissage d'un savoir être. Il est clair qu'actuellement, il semble difficile d'embrasser tout le problème; des effets à plus long terme ne se manifestent pas pour l'heure. Bien que prenant largement en compte les effets qualitatifs, il est souvent peu facile de mesurer ou d'apprécier toutes les répercus- 191 sions de l'EAO (tant sur les formés, sur le formateur que sur 1' entreprise). Exceptées quelques formes d'utilisation avec certains publics, l'intégration de l'EAO se montre, dans la plupart des cas, efficace. Certes, l'autoformation, le libre accés posent des difficultés notamment lors de la mise à disposition de populations de bas niveaux. Cependant, le recensement de tous ces effets, dans l'ensemble plutôt positifs, ne doit en rien cacher quelques limites de l'outillui-même ou de son utilisation. Limites de l'efficacité de I'EAO : Pour une étude plus précise, il convient de distinguer les limites liées à l'outil lui-même et celles relatives à son utilisation. Limites liées à l'outillui-même : En premier lieu, il faut mentionner les problèmes liés à la qualité des matériels. Les problèmes techniques d'une part, sont encore relativement présents sur les divers terrains : lancement du didacticiel, dysfonctionnement/interruption du didacticiel, accès au module désiré ... D'autre part, un nombre encore significatif de didacticiels se montrent médiocres. Il est s(\r que l'analyse des réponses fournies par l'apprenant soulève souvent des problèmes. En l'occurence, la non acceptation de réponses justes par le didacticiel se trouve très frustrante pour l'élève. On discerne parfois des difficultés de déchiffrage de lecture ou de saturation rapide suite à 1' abondance de messages écrits. Les formés ne lisent alors plus; ils balaient des yeux l'écran. Aucune acquisition n'est donc possible. 192 Il est certain que la production de tels logiciels nécessite des personnes très compétentes ayant une expérience riche dans ce domaine. La structure ARDEMI relève ce défi mais un enrichissement de la palette proposée est encore nécessaire. Il sera véritablement possible d'appréhender toute l'efficacité potentielle de l'outil seule" ment lorsqu'un panel très large de didacticiels s'utilisera. L'intérêt se verra peut-être renforcé si les responsables de formation dispo~ent de 11 briques 11 emboitables leur permettant de composer un cours à leur convenance. Cela suscite le dépassement de beaucoup de contraintes techniques et l'homogénéisation des langages. En second lieu, la dimension des effets ne semble pas devoir être négligée. Par son individualisation forte, l'EAO implique réellement chaque personne. Un phénomène de jugement émis par le groupe sur chacun de ses membres est ressenti parfois plus durement qu'en formation traditionnelle. Les stagiaires arrivant déjà avec un relatif complexe d'infériorité se sentent encore plus gênés car appréciés intrinséquement par leurs collègues ou le formateur. Cette plus grande mise en relief des différents niveaux de chacun accentue quelquefois des situations d'échecs déjà mal vécues antérieurement en période scolaire. Pour ces cas précis, le rôle du formateur devient très fort. A cet égard, soulignons la dimension affective de la relation enseignant/enseigné souvent clé de voüte de tout apprentissage (en particulier avec des apprenants en difficultés). Cet aspect relationnel se trouve modifié dès lors que l'instructeur disparait ou intervient beaucoup moins pendant le stage. Pour certains apprenants, l'aspect convivial et parfois ludique de l'EAO les rend un peu distants face à cette forme d'apprentissage. Assimilant ces logiciels à des jeux, ils ne traitent pas leur travail 193 devant les micro-ordinateurs avec autant de "sérieuxn et d"'application" qu'ils ne le feraient devant un livre, une fiche .... voire même un enseignant. Se tenir devant un écran relève pour certains de la même démarche qu'une présence active devant un jeu informatique ou électronique. Limites liées à l'utilisation de l'outil: Que le cadre de l'utilisation de l'EAO soit une totale autoformation ou un travail individuel avec présence de l'enseignant, le stagiaire se trouve dans l'obligation d'apprendre à apprendre. Or, la tendance de 1 'apprenant à progresser trop vite, ou à croire en une assimilation très rapide du cours peuvent le décourager lorsqu'il prend conscience qu'il n'a pas compris. Une validation régulière de ses acquisitions semble nécessaire de façon à ce qu'il mesure ses assimilations et ses incompréhensions. Par ailleurs, lorsqu'il étudie un didacticiel relativement long, ou plusieurs logiciels successifs, un phénomène de saturation se produit, cela indépendamment de sa propre volonté. Il lui faut par conséquent, savoir ménager de temps à autre des pauses. L'ensemble des remarques précédentes liées à la nécessité d'apprendre à apprendre, montre donc à quel point l'efficacité de l'outil informatique dépend de l'organisation. Cette dernière doit être différente de celle de l'enseignement traditionnel et très rigoureuse. Une mise à disposition plus libre de l'outil demeure toujours possible mais il est bon alors de prendre en compte les points suivants. A l'heure actuelle, la mise en pratique de l'EAO (sous quelque forme que ce soit) a bien souvent pour élément moteur un formateur 194 ou responsable de foZ.mation croyant aux vertus de ce nouvel outil. Le problème principal à court terme est celui de la généralisation possible de l'EAO. Cette dernière dépend avant tout de la motivation de l'ensemble des formateurs. Il s'agit alors de casser les barrières d'appréhensions techniques et pédagogiques. Il est vrai que l'instructeur ne représente plus le seul détenteur du savoir, il partage la diffusion des connaissances avec les micro-ordinateurs. Son rôle s'en trouve modifié, il faut qu'il en accepte les nouvelles modalités. La liberté d'action au sein du cours, chère à l'enseignant, peut lui apparaître quelque peu limitée par 1 'introduction d'un cadre plus strict. D'ailleurs, les détracteurs de ce nouvel outil retiennent comm"~:mément comme argumentation cette pénétration d'un élément contraignant. L'intégration de l'EAO pose très vite le problème de la densité du matériel. Cela ne doit pas contribuer à la création d'un système trop sélectif même si l'entreprise accorde une priorité aux secteurs les plus productifs. Cependant, il ne s'agit en aucun cas de privilégier certains stagiaires aux dépens d'autres. Il est sûr qu'il est difficilement concevable d'envisager une mise en oeuvre rapide sur tous les terrains. Souvent, la solution de 11 Saupoudrage 11 de matériel ne représente pas une solution idéale. Néanmoins, il serait préjudiciable de voir se développer une certaine inégalité ayant pour origine des raisons géographiques (ordinateurs concentrés sur un site), matérielles (insuffisance notoire de micro-ordinateurs), pédagogiques (utilisation de l'EAO sur quelques domaines essentiellement). Il se comprend fort bien qu'en première étape, l'entreprise cherche à améliorer la formation auprès d'un nombre de personnes plus limité. Il est, en effet, préférable, dans un premier temps, de bien former une minorité plutôt que de s'adresser de façon médiocre à l'ensemble des travailleurs. De toute manière, cela ne peut se concevoir qu'en étape préliminaire servant de base à un développement plus large de l'outil. 195 La mise en oeuvre de l'EAO en autoformation sur ou près du poste de travail demande, de la part du supérieur hiérarchique immédiat une reconnaissance de la fonnation individuelle. Une attitude négative de sa part annihile toute idée d'enrichissement personnel. La massification de la formation par ouverture de centres-ressources accessibles en libre service, devra permettre à chacun de se former selon ses besoins. Une pédagogie de soutien pourrait faciliter le travail de publics en difficultés et leur apporter une aide précieuse. Cette structure accueillera bien évidemment les éléments déjà autonomes désireux de parfaire des connaissances mais aura aussi pour tâche d'aider les populations qualifiées de "bas ou sans niveaux 11 • Les principaux éléments relatifs aux coûts et à l'efficacité ayant été cernés, il convient maintenant de poser la question primordiale : L'introduction de l'EAO améliore-t-elle le rapport cotit-efficacité? LE RAPPORT COUT-EFF1CACITE: Comme nous avons pu le mettre en lumière à plusieurs reprises, les résultats des évaluations vont en général dans le sens d'une amélioration de ce rapport. Dans cette phase d'éclosion et, pour certains de début de maturation, on note essentiellement l'apport de meilleurs et de nouveaux effets. Il est sûr que cela sous-entend un mode d'utilisation positif de l'EAO tel que défini ci-avant. Dans ce premier temps, le rapport évolue favorablement du fait d'une meilleure efficacité de l'outil considéré. Il faut même signaler, 196 à ce niveau, que tous les effets possibles de la mise en oeuvre de 1 'EAO ne s_ont pas mis en lumière ; certains ne pouvant apparaître, pour l'entreprise, qu'à moyen et long termes. Au-delà de cette seule prise en compte des effets présents ou à venir, il est possible d'émettre l'hypothèse d'une baisse future des coûts. Elle peut intervenir à deux niveaux. Dans le cas de stages, les gains de temps d'apprentissage (intervenant parfois dans les durées de session) devraient agir sur les cursus complets de formation (cas des stages en plusieurs modules) et donc apporter des réponses plus rapides aux besoins de l'entreprise. L'individualisation de l'apprentissage et l'acquisition d'une certaine autonomie dans le travail permettront au formateur de s'absenter de manière plus significative ... ce qui est source d'une minoration des coûts. Cela suscite, il est vrai, une reformulation totale de la notion de formation et plus particulièrement de la place et du rôle de l'instructeur. La création et le développement de 11Centres-ressourcesu pose d'une autre manière la question du rapport coût-efficacité. Si l'on suppose que l'efficacité est identique à celle des stages spécifiques, les coûts liés au formateur se trouvent considérablement diminués. Seuls subsistent les coûts de "l'homme ressource" chargé du suivi des apprenants ainsi que ceux de la personne supervisant l'individu envoyé en formation (supérieur hiérarchique par exemple). Il est certain que nous ne pouvons, en l'état, qu'approcher timidement la question. Tout semble, à l'heure actuelle, encore fragile mais les deux pistes de réflexion dégagées nous paraissent, elles, suffisamment solides. Bibliographie 199 ARDO!NO, J. et BERGER, G.

Son intégration, sous quelque forme que ce soit, induit une multiplication des conditions d'apprentissage. De plus, son développement au sein d'institutions très diverses laisse apparattre un éventail très riche de potentialités. Le choix d'intégration de cette nouvelle technologie informatique repose avant tout sur les responsables de formation. Ces derniers doivent faire face à des questions particulières propres à l'entreprise pour laquelle ils agissent. D'une manière générale, l'EAO se considère principalement comme outil individuel ou quasi individuel (binôme). A l'heure ac~ tuelle, une utilisation collective ne retient pas les pr~orités. Bien que ne délaissant pas cette dimension, notre tYPologie privilégiera et gardera comme fil directeur cette perspective individuelle. Face à la.très grande diversité de mise en oeuvre de ce nouvel outil, nous retenons onze critères d'ordres organisationnel et pédagogique. L•imbrication entre les deux se trouvant assez forte, il semble difficile de séparer, dans la présentation, les deux dimansions. · - Le but L'introduction de l'EAO répond, selon les institutions rencontrées à~~ multitude-d'objectifs finals. Certaines entreprises axent le développement de ce nouvel auxiliaire pédagogique sur des objectifs culturels alors que d'autres l'introduisent dans le cur·sus mSme d'une formation. EA diplÔmant : exemple : modules préparant le brevet professionnel par unités capitalisables ••••• qUalifiant : exemple : préparation d'examens pour passage à l'échelon . s~périeur .ipportant une formation nouVelle à l'apprenant : l'individu appréhende des concepts et connaissances inconnues pour lui. mettant à jour les connaissances la personne confirme ses acquis "et les actualise (normes nouvelles, évolution technique •••• ) développant une cul ture générale - Le contexte Un nouvel outil pédagogique apparaît •••• il peut répondre à différents problèmes posés par la formation. Selon le cadre, il intervient dana un contexte différent. • Le lieu intégrant les formations existantes •· répondant à un énorme problème de formation difficile à résoudre par des enseignements traditionnels : massification de la formation améliorant quantitativement et qualitativement l'offre afin de mieux répondre au marché de la formation et faire face, ainsi, à la concurrence • Pour toute problématiqUe relative à l 1EA0 1 ce critère est fondamental. Aux différentes situations possibles, cOrrespond une utilisation particulière de l'EAO dans un site pr~- ci s. sur le poste de travail : l'ordinateur sert à l'exécution des tâches ·et conjointement à la formation dans un local ou une salle très proche du lieu de travail dans un centre pédagogique "ressource" proche intégrant l'EAO et d'autres moyens pédagogiques. dans le centre de formation à domicile : minitel actuellement, télématique dans un futur proche. - Le nombre de micro-ordinateurs L'implantation des micro-ordinateurs est très souvent sub·ordonnée au nombre de machines que possède 1 1 entreprise. De plus, leur choix d'affectation gestion+ EAO ou EAO seul pose de manière radicalement différente la question de son introduction. - Le moment un micro-ordinateur affecté à la formation pour un service .ou un secteur de l'entrepr~se quelques micro-ordinateurs disséminés dans un service une salle de ty-pe "laboratoire" regroupant un certain nombre d'ordinateurs un micro-ordinateur par personne servant à la fois au poste de travail et à la formation Suivant les orientations données, les moments d'utilisation de l'EAO diffèrent complètement. E A 0 --=============:: pendant le temps de travail hors du temps de travail - La manière Ce critère demeure lui aussi principal. Il co~stitue une des bases de la stratégie de développement de" 1 1EAO. E A 0 libre accès total : les formés travaillent à leur guise sans aucune "surveilla.ncen. libre accès contrôlé : les formés travaillent à leur guise mais s 1 inscrivent pour une séance et souvent font valider leur passage. intégré : 1 1EAO est introduit dans une formation conventionnelle conjointement au cours tradi tiom1el. Corrélativement à cette séparation, il faut-considérer 1 1 importance du suivi du fermé soit par sa hiérarchie immédiate soit par un responsable formation (ou autre personne). supervisé : le suivi est ass_uré par un hiérarchique ou E A 0 une autre personne non supervisé ·- Le public La nature du public ciblé doit être prise en compte lors de.la décision d 1intégration de llEAO. Ce nouvel outil apparaît parfois plus motivant pour des élèves totalement décon.~ectés de tout système de formation. pubiic très capti.t" : ce sOnt des personnes volontaires qui désirent se former. public captif : il représente la moyenne partie des formés, c 1 est-à-dire envoyés en formation pour acquérir de nouvelles connaissances. public à motiver : qualifié souvent de "difficile", ayant Vécu W'le scolarité en si tua ti on d1 échec permanent • . -L'unité de base Bien que demeurant essentiellement un outil indiv.iduel, l 1EAO peut se voir utilisé dans le cadre d'un groupe classe •••• un travail d'équipe facilitant pour certains leur travail.personnel. E A 0 - La nature individuel : une seule personne travaille devant la console quasi individuel : les formés interviennent par binômes ou trinSmes devant l'ordinateur. collectif_ : une seule console est utilisée dans la salle. Les informations apparaissent sur plusieurs écrans placés dans toute la pièce. L1EAO répond selon les cas, à une mission pédagogique· très particulière. Trois voiets se définissent ailÏsi apprentissage : le didacticiel apporte le "corpus" de connaissances complément : l 1EAO s'Utilise alors soit pour préparer une formation soit pour réviser des notions déjà appréhendées. e;x:erciseur 1 1EAO propose essentiellement des exercices d'application. Au niveau des compléments apportés par l'EAO, il faut distinguer trois aspects : avant la formation : révision pour mise à niveau des pré-requis. pendant la formation : selon les points abordés, il semble quelquefois nécessaire de reprendre plus particulièrement des notions. après la formation ~ le réinvestissement des connaissances n'est souvent pas immédiat, ·ainsi fautil revoir au moment ~pportun les . éléments nécessaires à la 'résolution d'un problème pratique. L'introduction de l 1EAO dans la formatien s'opère de manière très diversifiée. A ce stade de la réflexi on surgit la question très souvent posée : "l'EAO est-il un outil de substitution?" La pratique démontre une certaine difficulté pour répondre à une telle interrogation. E. A 0 substitution totale : le cours EAO remplace entière- _ment la formation tradition~ nelle. substitution partielle : "mode mixte", l'outil est introduit conjointement à une intervention du formateur. un outil supplémentaire : dans ce cas, il n'est plus question de substitution. L1EAO s'utilise en plus, parmi d'autres auxiliaires pédagogiques. L'objectif recherché repose sur la diversification des moyens pour un meilleur apprentissage. - La relation au formateur La part d'intervention du formateur rev~t une dimension importante. De plus, la nature même de ses prestations définit des rÔles .pédagogiques de l 1EAO totalemerit différents : EAO outil principal/outil secondaire. E A O. conduit : le formateur reste et apporte parallèlement aes éléments de connaissances. non conduit : le formateur s'absente. Plus significative encore apparaît la forme de ses interventions. -•. avec alternance : reprise synthétique et systé~atique par le formateur de ce qui a été vu dans le module. avec suivi : apports complémentaires d'explications par le formateur au fur et à mesure du déroulement du didacticiel. avec application pratique : autoformation avec réinvestissemant immédiat des connaissances dans des exercices soumis par le formateur. Selon les objectifs visés et la conception que l'on se fait de l 1EAO, les termes de réflexion sur l'opportunité d'introduction de ce nouvel outil varient. Le très grand nombre d'institutions rencontrées nous laisse entrevoir-une variété immense quant à sa mise en oeuvre. Cependant, une remarque de premier ordre s'impose. 1 ,-arrivée progressive actuelle de 1 'EAO sur les différents "te:::-rains" permet, le plus souvent, de valider ou pas, les hypothèses émiSes sur la forme d'utilisation de cet auxiliaire pédagogique. Il est, de ce fait, possible que certaines situations développées dans cette typologie-disparaissent naturellement. Quoi qu'il en soit, le pQint clé de toute considération concernant la pédagogie de l 1EAO appartient à la place du formateur. De sa présence ou non, en découle tout un éventail d'utilisations différentes de ce nouveau moyen d'enseignement. Au-delà de cet aspect principal, ce nouvel outil doit manifester des effets à la fois sur les_ formés, le formateur et le système de formation.

Gregory Mankiw est professeur d’économie à l’Université de Harvard. Il a étudié l’économie à l’Université de Princeton et au Massachusetts Institute of Technology (MIT). Il a enseigné la macroéconomie, la microéconomie, les statistiques et les principes de l’économie. Le professeur Mankiw est un écrivain très prolifique ; il est aussi très présent dans les débats économiques et politiques. En plus de ses activités d’enseignement, de recherche et d’écriture, le professeur Mankiw a été chercheur au National Bureau of Economic Research (NBER) et conseiller auprès de la Réserve fédérale de Boston et du Congressional Budget Office (Bureau du Budget du Congrès américain). De 2003 à 2005, il a été président du US President’s Council of Economic Advisors (littéralement, président du Conseil des Conseillers économiques du Président américain). Il a aussi été conseiller de Mitt Romney lors de la campagne électorale américaine de 2012. Le professeur Mankiw vit à Wellesley, dans le Massachusetts, avec sa femme Deborah, leurs trois enfants et leur border terrier, Tobin. Mark P. Tayl or est doyen de la Business School de l’Université de Warwick et professeur de finance internationale. Il est diplômé en philosophie, en science politique et en économie de l’Université d’Oxford. Il a obtenu un master, puis un doctorat en économie et finance internationale à l’Université de Londres. Le professeur Taylor a enseigné l’économie dans de nombreuses universités (incluant Warwick, Oxford, New York), à des niveaux différents (depuis des cours d’introduction jusqu’à des cours de 3e cycle ). Il a été économiste senior auprès du Fonds monétaire international et de la Banque d’Angleterre et avant d’être nommé doyen de l’Université de Warwick, il a été directeur général de BlackRock, le plus grand organisme de placement collectif au monde. Il était en charge de l’étude de l’allocation internationale des actifs du point de vue de l’analyse macroéconomique. Ses travaux ont été publiés dans des revues académiques et il fait partie aujourd’hui des économistes les plus cités dans le monde de la recherche. Le professeur Taylor vit en famille dans une ferme du quinzième siècle près de Stratford sur Avon dans le Warwickshire ; il y collectionne des pendules et élève des abeilles. Le contrIbuteur Andrew Ashwin a plus de 20 ans d’expérience en tant que professeur d’économie. Il est titulaire d’un MBA et rédige une thèse de doctorat portant sur la notion de seuil en X PrinciPes de l’économie économie. Andrew est un auteur expérimenté qui a conçu des manuels pour étudiants de différents niveaux. Andrew est président du collège des examinateurs d’un organisme d’accréditation en économie et gestion de premier plan et est éditeur de la revue de l’Economics, Business and Enterprise Association (EBEA). Il est aussi rédacteur pour le site internet Biz/ed basé à l’université de Bristol et consultant pour le régulateur britannique Ofqual. Andrew, qui développe un intérêt particulier pour l’enseignement et l’évaluation en économie est membre expert du Chartered Institute of Educational Assessors. Andrew vit dans le Rutland avec sa femme Sue et ses jumeaux Alex et Johnny. AVANT-PROPOS La quatrième édition de « Principes de l’Économie » est différente des deux précédentes. Tenant compte des remarques des utilisateurs, étudiants et enseignants, son contenu a été remanié, de nouvelles sections traitent en profondeur les grandes questions de la micro et de la macroéconomie. Cette édition est, comme les précédentes, une adaptation européenne du célèbre ouvrage de Mankiw. Elle a ainsi son identité propre, qui la différencie de la version américaine originale. Les auteurs ont cependant eu à cœur de conserver le style dynamique et le caractère abordable de cet ouvrage d’introduction à l’économie. L’analyse économique fait référence à toutes les situations de notre quotidien et les concepts fondamentaux peuvent s’appliquer à un ensemble d’expériences bien réelles. « L’économie est une étude de l’humanité dans l’activité ordinaire de la vie » : voici qu’écrivit Alfred Marshall, le grand économiste britannique du 19e siècle dans son livre, Principe s d’ économie pol itique . Gardez cela à l’esprit, à mesure que vous progresserez dans votre étude de l’économie. Alors même que les actualités focalisent sur le monde de la banque et de la finance, les impôts et la politique économique, l’analyse économique offre bien plus qu’un simple aperçu de ces thématiques. Elle permet de comprendre le processus de formation d’un ensemble de décisions de la vie courante. Par exemple, vous avez l’intention de voyager, mais vous vous étonnez du prix qu’il vous faut payer pour être vacciné contre des maladies tropicales. Partirez-vous quand même ? Alors que vous vous apprêtez à éviter une dépense substantielle, ne pensez-vous pas que ce prix reste bien faible lorsqu’il est comparé au coût de tomber gravement malade, vous et votre famille ? Ces questions sont du même ordre que celles liées à la fixation du taux d’intérêt de la politique monétaire ou aux décisions d’investir des firmes. Bienvenue dans le monde merveilleux de l’économie – apprenez à penser comme un économiste et un monde nouveau s’ouvrira à vous.

Avec ces compléments, les étudiants sont actifs : ils interagissent avec le contenu du manuel, visualisent les effets concrets de certains événements, reconstruisent par eux-mêmes les concepts économiques et leur utilisation. Les compléments sont insérés sous forme de pictogrammes dans la version numérique NOTO. Ils précisent, détaillent et approfondissent les sections et les notions importantes des principaux chapitres pour conduire les étudiants à s’approprier par eux-mêmes les connaissances. Ils incluent des documents additionnels, des animations et des explications supplémentaires à celles comprises dans le manuel. Ils incluent aussi des questions/réponses pour permettre aux étudiants de s’assurer par eux-mêmes de la maîtrise des notions, définitions et concepts importants. Ils comprennent également un grand nombre de graphiques, figures et tableaux en complément de ceux du manuel. Les compléments ont ainsi été conçus pour inciter les étudiants à développer leur esprit critique lorsqu’ils lisent un ouvrage et à faire des liens entre leurs lectures et leurs connaissances préalablement acquises. Pour chacun des principaux chapitres, des exercices sont proposés. Ces exercices sont de niveaux de difficulté croissants et possèdent tous un solutionnaire détaillé. Les étudiants peuvent ainsi évaluer leur apprentissage et se préparer efficacement à leurs examens. Il est possible d’imprimer ces exercices ou leur solution au besoin. Enfin, un livret de rappels mathématiques et un livret de rappels méthodo logiques. Ces livrets permettent aux étudiants de réviser les mathématiques nécessaires à la compréhension du manuel. Les rappels méthodologiques sont fournis pour aider les étudiants à présenter leurs réponses lors d’examens et de travaux. Des outILs InteractIFs et InnoVants Les compléments multimédias associés aux Principe s de l’économie de Mankiw-Taylor offrent plusieurs outils interactifs et innovants. XVi PrinciPes de l’économie Des animations avec voix-off Les compléments multimédias et les exercices comptent plus d’une centaine d’animations avec voix-off. Ces animations permettent de suivre visuellement la manière dont certains graphiques ou figures du manuel sont construits, tout en écoutant les commentaires. Elles offrent une version animée de certains raisonnements du manuel. Les compléments numériques XVII Elles permettent d’approfondir certaines affirmations ou concepts du manuel difficilement accessibles au premier abord. Par ailleurs, certaines animations ont été scénarisées pour familiariser les étudiants avec les raisonnements théoriques sous-jacents utilisés dans les outils de simulation interactifs. Des outils de simulation interactifs Des simulations permettent aux étudiants d’analyser par eux-mêmes les conséquences d’un choc macroéconomique. Un choc et une situation initiale sont tirés aléatoirement et les étudiants analysent les conséquences de ce choc en sélectionnant des actions qui sont jouées graphiquement au fur et à mesure. XViii PrinciPes de l’économie Ces simulations ont été développées avec une interaction conviviale. Elles permettent d’appliquer les concepts étudiés avec des exemples concrets et de visualiser directement les effets de chaque étape de l’analyse du choc. Vidéos 85 exercices sont corrigés à l’aide de vidéos. Ces vidéos ont été développées pour faciliter l’apprentissage de concepts économiques abstraits. En visualisant la manière dont un économiste pose puis résout un problème donné, les étudiants acquièrent des réflexes qu’ils peuvent ensuite mobiliser dans leurs échanges avec leurs professeurs ou lors de leurs examens. Par ailleurs, ces vidéos permettent de revoir à loisir les corrections de ces exercices. Les compléments numériques XIX Certaines démonstrations sont également faites à l’aide de vidéos, afin d’aider les étudiants à les assimiler. un aPPrentIssaGe FacILItÉ Les compléments associés aux Principe s de l’économie de Mankiw -Taylor facilitent l’acquisition des connaissances en associant les trois systèmes de perception actifs dans tout apprentissage : le visuel, l’auditif et le kinesthésique. Les animations avec voix-off font appel au système de perception visuel et auditif des étudiants. Une centaine de problèmes de synthèse sont corrigés par des vidéos permettant aux étudiants de visualiser et d’écouter la manière dont un économiste pose puis résout un problème donné. Des outils de simulation reprennent la même interface que certaines animations et permettent aux étudiants de mettre en œuvre leurs connaissances en faisant appel au système de perception kinesthésique des étudiants. De la même manière, tout au long de l’analyse guidée, l’attention des étudiants est sollicitée par des questions sur les concepts théoriques immédiatement abordés dont la réponse est directement accessible.

Le mot économie a une origine grecque, oikonomos, il signifie « celui qui gère la maison ». À première vue, cette étymologie peut paraître surprenante, mais en réalité les ménages et les économies ont beaucoup de choses en commun. Un ménage fait face à de nombreuses décisions. Il doit décider qui effectue quelles tâches et ce que chacun reçoit en retour : qui prépare le dîner ? Qui lave le linge ? Qui aura une tranche de gâteau supplémentaire à l’heure du thé ? Qui choisit le programme télévisé ? En bref, le ménage doit allouer ses ressources rares entre ses différents membres en prenant en compte les capacités, les efforts et les souhaits de chacun. Au même titre qu’un ménage, une société est confrontée à de nombreuses décisions. Une société doit décider des emplois nécessaires et qui les occupera. Elle a besoin de personnes qui produisent de la nourriture, d’autres qui confectionnent des vêtements et d’autres encore qui créent des logiciels. Une fois que la société a affecté les hommes (ainsi que la terre, les bâtiments et les machines) aux différents emplois, elle doit aussi répartir les quantités de biens et de services produits. Elle doit décider qui mange du caviar et qui mange des pommes de terre. Elle doit décider qui conduit une Jaguar et qui prend le bus. 1.1.1 Le problème économique Ces décisions sont représentatives de ce que l’on peut appeler « le problème économique ». T oute société doit répondre à trois questions : Ɣ quels biens et services devraient être produits ? Ɣ comment ces biens et services devraient être produits ? Ɣ à qui sont destinés ces biens et services produits ? Les réponses à ces questions seraient simples si les ressources étaient si abondantes que la société pourrait produire tout ce que les individus désirent. Il n’en est rien. La société ne dispose jamais assez de ressources pour produire tous les biens désirés et répondre aux besoins de ses citoyens. Ces ressources peuvent être classées dans une de ces trois grandes catégories : Ɣ la terre – Il s’agit de toutes les ressources naturelles de la planète. Elles incluent les minerais de fer, d’argent, d’or, de cuivre, les poissons des océans, le charbon et toutes les ressources alimentaires issues de la terre. Dans son ouvrage de 1817, Principe s de l’économie pol itique et de l’impôt , David Ricardo parle des « facultés primitives et indestructibles du sol ». Ɣ le travail – Il s’agit de l’effort humain, physique et intellectuel, appliqué à la production. Les activités d’un technicien qui fabrique des outils de précision, d’un banquier spécialisé dans les investissements, d’un balayeur, d’un enseignant sont toutes des formes de travail. Ɣ la capital – Il s’agit de l’équipement et des structures utilisées pour produire des biens et des services. Les biens capitaux incluent les machines dans les usines, les bâtiments, Dix principes de l’économie 5 les tracteurs, les ordinateurs, les fours,… en bref, tout ce qui n’a pas d’autre destination que la contribution à la production. Ź Terre toutes les ressources naturelles de la planète Ź Travail l’effort humain, intellectuel et physique, dédié à la production Ź Capital l’équipement et les structures utilisés pour produire des biens et services 1.1.2 Rareté et choix La gestion des ressources de la société est importante car les ressources sont rares. La rareté signifie que les ressources existent en quantités limitées et que la société ne peut pas produire tous les biens et services que les individus souhaiteraient avoir. De la même manière qu’un ménage ne peut pas donner à chacun de ses membres tout ce qu’il désire, une société ne peut pas faire accéder chaque individu au niveau de vie auquel il aspire. L’économie est l’étude de la manière dont la société gère ses ressources rares, elle tente de répondre aux trois questions posées précédemment. Dans la plupart des sociétés, l’allocation des ressources résulte de l’action combinée de millions de ménages et de firmes au sein d’un système de marchés. Les économistes : Ɣ étudient comment les individus prennent leurs décisions : combien d’heures ils travaillent, ce qu’ils achètent, combien ils épargnent et comment ils investissent leur épargne, Ɣ étudient aussi comment les individus interagissent les uns avec les autres. Par exemple, ils examinent comment la multitude d’acheteurs et de vendeurs d’un bien détermine le prix auquel le bien est vendu et en quelle quantité, Ɣ analysent les forces et les tendances qui affectent l’économie dans sa globalité, incluant la croissance du revenu moyen, la part de la population qui ne peut pas trouver de travail et le taux auquel les prix augmentent. Ź Rareté la caractéristique des ressources économiques qui existent en quantités limitées Ź Économie l’étude de la façon dont l’économie gère ses ressources rares Bien que l’étude de l’économie comporte de nombreuses facettes, cette discipline est structurée autour de plusieurs idées majeures. Dans le reste de ce chapitre, nous nous intéresserons aux Dix pr incipe s de l’économie. Ne vous inquiétez pas si vous ne les comprenez pas tous tout de suite, ou si vous ne les trouvez pas complètement convaincants. Dans les chapitres suivants, nous explorerons ces idées plus en détail. Les dix principes sont exposés ici pour que vous puissiez vous faire une idée générale de l’analyse économique. Vous pouvez concevoir ce chapitre comme une « mise en bouche ». 6 introduction à l’économie 1.2 comment Les InDIVIDus Prennent Leurs DÉcIsIons Le terme « économie » n’a rien de mystérieux. Que l’on parle de l’économie d’un groupe de pays comme l’Union européenne ou de l’économie d’un pays en particulier, comme la France, ou du monde entier, une économie est juste un groupe d’individus qui interagissent au quotidien. L’économie fait référence à toutes les activités de production et d’échange qui se déroulent chaque jour – tous les achats et toutes les ventes. Le niveau d’activité économique est une mesure de tout ce qui est acheté et vendu dans l’économie pour une période donnée. Ź L’économie toutes les activités de production et d’échange qui se déroulent chaque jour Ź L’activité économique la mesure des achats et des ventes dans l’économie, pour une période donnée Puisque le comportement d’une économie reflète le comportement des individus qui la composent, nous débutons notre étude de l’économie par les quatre principes de la prise de décision. 1.2.1 Principe 1 : Les individus font face à des arbitrages La première leçon relative à la prise de décision peut se résumer par un adage familier aux économistes : « il n’y a pas de repas gratuit ». Pour obtenir quelque chose que nous aimons, nous devons généralement abandonner quelque chose d’autre que nous aimons aussi. Prendre une décision signifie arbitrer entre différents objectifs. Considérons un étudiant qui doit décider de quelle manière il va répartir la ressource la plus importante dont il dispose – son temps. Il peut passer tout son temps à étudier l’économie, il peut passer tout son temps à étudier la psychologie, ou encore il peut partager son temps entre les deux disciplines. Pour chaque heure qu’il passe à étudier une matière, il renonce à une heure qu’il aurait pu passer à étudier l’autre matière. De même, pour chaque heure passée à étudier, il renonce à une heure passée à faire de la gymnastique, à rouler à vélo, à regarder la télévision, à faire la sieste ou à travailler à temps partiel pour gagner un peu d’argent de poche. Intéressons-nous maintenant aux parents qui doivent décider de la façon de dépenser le revenu familial. Ils peuvent acheter de la nourriture, des vêtements ou se payer des vacances. Alternativement, ils peuvent aussi épargner une part du revenu familial pour leur retraite ou pour aider leurs enfants à s’acheter un logement plus tard. Lorsqu’ils décident de dépenser un euro supplémentaire pour l’un de ces biens, ils ont un euro en moins à dépenser pour acquérir un autre bien. Lorsque les individus sont regroupés au sein de sociétés, ils font face à différents types d’arbitrages. L’arbitrage classique est celui qui porte sur les dépenses liées à la défense nationale ou à l’alimentation. Plus nous investissons dans la défense nationale Dix principes de l’économie 7 pour protéger nos frontières des agressions extérieures, moins nous pouvons acheter de biens de consommation afin d’augmenter notre niveau de vie à l’échelle de la nation. Un arbitrage tout aussi important dans la société moderne est celui qui concerne un environnement sain et un haut niveau de revenu. Les lois qui imposent aux firmes la réduction de la pollution poussent à la hausse les coût s de production des biens et services. Du fait de ces coût s plus élevés, les firmes finissent par dégager des profits moindres, payer des salaires plus faibles, augmenter les prix ou recourir à une combinaison de ces trois éléments. Ainsi, alors que la réglementation de la pollution nous fait bénéficier d’un environnement plus sain et de meilleures conditions sanitaires qui lui sont associées, elle a pour prix la réduction des revenus des entrepreneurs, des travailleurs et des clients des entreprises. Un autre arbitrage rencontré par la société est celui qui concerne l’efficacité et l’équité. L’efficacité signifie que la société tire le meilleur parti de ses ressources rares. L’équité signifie que les produits de ces ressources sont distribués de manière juste entre les membres de la société. En d’autres termes, l’efficacité représente la taille du gâteau économique et l’équité représente la façon selon laquelle le gâteau est partagé. Souvent, lorsque l’État élabore ses politiques, les deux objectifs entrent en conflit. Ź Efficacité la propriété qui caractérise une économie capable de tirer le meilleur parti de ses ressources rares Ź Équité la propriété qui caractérise une économie capable de distribuer les richesses de manière équitable entre ses participants Prenons le cas, par exemple, de politiques visant à atteindre une distribution plus équitable du bien-être économique. Certaines de ces mesures, telles que le système de sécurité sociale ou l’assurance chômage cherchent à soutenir les membres de la société qui sont le plus en difficulté. D’autres mesures, comme l’impôt sur le revenu, imposent à ceux qui ont une situation financière positive de contribuer plus que les autres à l’action de l’État. Alors même que ces politiques ont pour résultat davantage d’équité, elles ont un coût qui se traduit par une efficacité réduite. Lorsque l’État redistribue le revenu des riches vers les pauvres, il réduit la rémunération du travail et par conséquent les individus travaillent moins et produisent moins de biens et services. En d’autres termes, lorsque le gouvernement essaie de couper le gâteau économique en parts plus égales, le gâteau se rétrécit. Reconnaître que les individus sont confrontés à des arbitrages ne nous renseigne pas vraiment sur les décisions qu’ils prendront ou devraient prendre. Un étudiant ne devrait pas cesser d’étudier la psychologie, ce qui aurait pour effet d’augmenter le temps disponible pour l’étude de l’économie. La société ne devrait pas cesser de protéger l’environnement pour la simple raison que les réglementations environnementales réduisent notre train de vie. Les pauvres ne devraient pas être ignorés parce que l’aide qui leur est apportée influence les incitations à travailler. Néanmoins, il est important de reconnaître les arbitrages de la vie quotidienne car il n’est de bonne décision qu’en connaissance des différentes alternatives. 8 introduction à l’économie Testez-vous Est-ce que l’adage « il n’y a jamais de repas gratuit » se réfère simplement au fait que quelqu’un doit payer pour avoir un repas, ou bien cela signifie-t-il que le bénéficiaire de ce repas gratuit supporte également un coût ? 1.2.2 Principe 2 : Le coût d’une chose mesure ce à quoi on renonce pour l’obtenir Puisque les individus font face à des arbitrages, la prise de décision nécessite de comparer les coût s et les bénéfices des alternatives qui se présentent. Dans de nombreux cas, cependant, le coût d’une action n’est pas facile à déterminer. Considérons, par exemple, la décision d’étudier à l’université. L’avantage associé en est l’enrichissement intellectuel personnel ainsi qu’un ensemble d’opportunités professionnelles de qualité tout au long de la vie active. Mais quel en est le coût ? Afin de répondre à cette question, vous seriez tenté d’additionner les montants dépensés au titre des frais de scolarité, des livres, du logement et de la nourriture. En fait, ceci ne représente pas réellement ce à quoi vous renoncez pour étudier une année à l’université. Le premier problème associé à ce type de réponse provient de ce qu’elle inclut des éléments qui ne sont pas vraiment des coût s liés à aux études universitaires. Même si vous renoncez à étudier à plein temps, vous avez toujours besoin d’un endroit pour dormir et vous devez aussi vous nourrir. Le logement et la nourriture ne font partie des coût s des études supérieures que dans la mesure où ils sont plus élevés à l’université qu’ailleurs. De même, il est possible que les coût s du logement et de la nourriture à l’université soient moins élevés que le loyer et les dépenses que vous supporteriez en vivant de manière indépendante. Dans ce cas, les économies réalisées sur le logement et la nourriture sont de réels avantages résultant de la décision d’étudier à l’université. Le deuxième problème découlant de cette manière de calculer les coûts est qu’elle ignore le coût le plus important lié aux études supérieures – le temps personnel des individus. Lorsque vous consacrez une année à suivre des cours, lire des livres et rédiger des dissertations, vous ne pouvez pas dédier ce temps à une activité professionnelle. Pour la plupart des étudiants, les salaires qu’ils sacrifient représentent le coût le plus important de leurs études supérieures. Le coût d’opportunité d’une chose mesure ce à quoi il faut renoncer pour l’obtenir. Lors du processus de décision concernant, par exemple, les études supérieures, ceux qui décident doivent être conscients des coûts d’opportunité associés à chaque action possible. En réalité, ils en sont généralement conscients. Les joueurs de football en âge d’étudier à l’université et qui pourraient gagner des millions en abandonnant leurs études pour jouer au niveau professionnel sont bien conscients de l’importance du coût d’opportunité. Il n’est pas surprenant qu’ils décident que, finalement, le jeu n’en vaille pas la chandelle. Ź Coût d’opportunité ce à quoi il faut renoncer pour obtenir quelque chose Dix principes de l’économie 9 Testez-vous Supposons que les coûts suivants sont supportés par un étudiant pour trois années d’études à l’université : coût d’inscription de 9 000 euros par an = 27 000 euros ; logement pour un coût moyen de 4 500 euros annuels = 13 500 euros ; coût d’opportunité représentant la perte de revenu potentiel évalué à 15 000 euros annuels = 45 000 euros ; coût total = 85 500 euros. Étant donné ce coût relativement élevé, pourquoi aller à l’université ? 1.2.3 Principe 3 : Les individus rationnels raisonnent à la marge Les décisions courantes sont rarement du type « tout ou rien », elles sont habituellement plus nuancées. Au moment du dîner, la décision n’est pas de savoir si on va jeûner ou au contraire s’empiffrer, on doit juste déterminer si on va se resservir en frites. Lorsque la période d’examens se rapproche, la décision n’est pas de tout rater ou de réviser 24 heures par jour, mais de réviser une heure supplémentaire au lieu de regarder la télévision. Les économistes utilisent l’expression « variation marginale » pour décrire les petites variations autour d’un plan d’action donné. Rappelez-vous que le terme « marge » signifie « limite » et par conséquent les variations marginales sont des ajustements aux limites de l’action en cours. Ź Variations marginales ajustements de faible ampleur concernant un plan d’action choisi Dans de nombreuses situations, les individus prennent les meilleures décisions possibles en raisonnant à la marge. Supposons par exemple que vous vous intéressez à l’opportunité de compléter vos études supérieures par un master. Afin de trancher, vous devez identifier les avantages résultant de cette année supplémentaire (des salaires élevés tout au long de votre vie et l’immense joie d’apprendre) ainsi que les coûts additionnels que vous devrez supporter (une année supplémentaire de frais de scolarité et une année de salaire sacrifiée). En comparant ces avantages marginaux à ces coûts marginaux, vous pouvez déterminer en quoi cette dernière année vaut la peine d’être effectuée. Un décideur rationnel entreprend une action si et seulement si l’avantage marginal de cette action est supérieur au coût marginal. 1.2.4 Principe 4 : Les individus réagissent aux incitations Puisque les individus prennent leurs décisions en comparant les avantages et les coûts, leur comportement peut aussi changer lorsque les coûts ou les avantages se modifient. Cela signifie que les individus réagissent aux incitations. Lorsque, par exemple, le prix des pommes augmente, les individus décident de manger plus de poires et moins de pommes puisque le prix d’achat d’une pomme est plus élevé. En même temps, les exploitants des vergers décident d’embaucher plus d’ouvriers et de récolter plus de pommes, puisqu’il est devenu 10 introduction à l’économie encore plus avantageux de vendre une pomme. Comme nous le verrons, connaître l’effet du prix sur le comportement des acheteurs et des vendeurs sur un marché – en l’occurrence, le marché des pommes – est crucial pour comprendre comment l’économie fonctionne. Les décideurs publics ne devraient jamais oublier les incitations car de nombreuses politiques changent les coût s et les avantages auxquels les individus sont confrontés et, par conséquent, modifient les comportements. Une taxe sur l’essence, par exemple, encourage les automobilistes à conduire des voitures plus petites et plus économiques. Elle encourage aussi les automobilistes à utiliser les transports en commun plutôt qu’à prendre leur voiture, et à se rapprocher de leur lieu de travail. Si la taxe était suffisamment importante, les automobilistes commenceraient à conduire des voitures électriques. Lorsque les décideurs publics échouent à identifier comment leurs politiques affectent les incitations, ils obtiennent des résultats non désirés. Par exemple, le gouvernement britannique a accordé un allègement fiscal aux propriétaires de locaux vides afin de les inciter à les remettre sur le marché. Or, cette mesure a été décidée au moment où l’économie rentrait en récession et les propriétaires ont eu les plus grandes difficultés à trouver des locataires pour leurs locaux. Certains propriétaires ont alors estimé qu’il valait mieux détruire les immeubles vides plutôt que payer la taxe. Était-ce le résultat attendu par l’État ? Certainement pas. Cet exemple illustre bien le fait que les individus réagissent aux incitations. Certaines d’entre elles, étudiées par les économistes sont évidentes, d’autres sont plus complexes. Personne n’est surpris d’apprendre que les automobilistes préfèrent acheter des voitures plus petites lorsque le prix de l’essence augmente du fait de nouvelles taxes. En revanche, les effets de la suppression des allègements fiscaux sur les locaux vides ne sont pas faciles à prévoir. Lorsque l’on analyse n’importe quelle politique, il est nécessaire de prendre en compte non seulement les effets directs mais aussi les effets indirects qui passent par les incitations. Si la politique modifie les incitations, les individus modifieront en retour leur comportement. Testez-vous De nombreuses personnes sont sans emploi en Europe, elles demandent des allocations-chômage. Les gouvernements essaient de réduire la dépense publique, mais sont contraints de dépenser davantage en allocations-chômage. Quelles sortes d’incitations les gouvernements pourraient-ils mettre en place afin d’encourager les chômeurs à trouver un emploi au plus vite ? Quelles pourraient être les conséquences inattendues des schémas d’incitations que vous proposez ? 1.3 comment Les InDIVIDus InteraGIssent Les quatre premiers principes portaient sur la manière selon laquelle les agents forment leurs décisions. En ce qui nous concerne personnellement, nombreuses sont nos décisions qui, Dix principes de l’économie 11 non seulement nous affectent nous-mêmes, mais ont aussi un effet sur les autres. Les trois principes suivants concernent la façon dont les agents interagissent les uns avec les autres. 1.3.1 Principe 5 : L’échange est profitable pour tous Les Américains et les Chinois sont souvent présentés dans les actualités comme les concurrents des Européens dans l’économie mondiale. À certains égards, cela est vrai car les firmes américaines et chinoises produisent souvent les mêmes biens que les firmes européennes. Les fabricants de jouets se concurrencent pour conquérir les mêmes clients dans le marché de l’aéronautique. Toyota et Citroën se battent pour les mêmes acheteurs sur le marché des jouets. Les producteurs de fruits se font concurrence pour les mêmes clients sur le marché des fruits. Aussi est-il facile de se tromper lorsque l’on pense à la concurrence entre les pays. Le commerce, ou échange international, entre l’Europe et les États-Unis ou entre l’Europe et la Chine n’est pas assimilable à une compétition sportive, au terme de laquelle il y a un gagnant et un perdant (c’est ce que l’on appelle un jeu à somme nulle). En fait, c’est le contraire qui se produit : l’échange entre deux économies peut améliorer la situation de chacune de ces économies. Pour le comprendre, considérons comment l’échange affecte votre famille. Lorsqu’un membre de votre famille cherche un emploi, il entre en concurrence avec des membres d’autres familles qui cherchent aussi un emploi. Les familles se concurrencent aussi lorsqu’elles vont faire leurs courses, car chacune d’entre elles veut acheter les meilleurs produits au meilleur prix. Ainsi, en un certain sens, d’un point de vue économique, chaque famille se bat contre toutes les autres familles. En dépit de cette concurrence, votre famille ne gagnerait pas à s’isoler des autres familles. Dans ce cas, elle devrait produire sa propre nourriture, fabriquer ses propres vêtements et construire sa propre maison. De toute évidence, votre famille retire beaucoup de sa capacité à échanger avec les autres. L’échange permet à chaque personne de se spécialiser dans les activités pour lesquelles elle est la meilleure, qu’il s’agisse d’élevage, de couture ou de construction. En échangeant avec les autres, les individus peuvent accéder à une plus grande variété de biens et ce, à un coût plus faible. Comme les familles, les pays retirent aussi un avantage de leur capacité à échanger les uns avec les autres. Le commerce permet aux pays de se spécialiser dans ce qu’ils font le mieux et de bénéficier d’une plus grande variété de biens et de services. Les Chinois et les Américains, comme les Coréens et les Brésiliens, sont tout autant nos partenaires dans l’économie mondiale qu’ils sont nos concurrents. 1.3.2 Principe 6 : Les économies de marché sont habituellement un bon mode d’organisation de l’activité économique L’effondrement du communisme dans l’Union Soviétique et dans l’Europe de l’Est au cours des années 1980 est certainement l’un des changements les plus importants intervenus dans le monde au cours du dernier demi-siècle. Le fonctionnement des pays communistes reposait sur le principe selon lequel les planificateurs centraux au pouvoir étaient 12 introduction à l’économie les mieux à même de guider l’activité économique et répondre aux trois questions du problème économique. Ces planificateurs déterminaient quels biens étaient produits, en quelle quantité, par qui et pour qui. La théorie sous-jacente à la planification centralisée prévoyait que seul le gouvernement pouvait organiser l’activité économique de manière à promouvoir le bien-être du pays dans son intégralité. Aujourd’hui, la plupart des pays qui adoptèrent par le passé les économies centralisées ont abandonné ce système et essaient de développer des économies de marché. Dans une économie de marché, les décisions d’un planificateur central sont remplacées par les décisions de millions de firmes et de ménages. Les firmes décident qui embaucher et que produire. Les ménages décident pour quelles firmes travailler et comment dépenser leur revenu. Ces firmes et ces ménages interagissent au sein du marché et les prix ainsi que leur intérêt personnel guident leurs décisions. Ź Économie de marché une économie qui alloue les ressources au travers des décisions décentralisées des nombreuses firmes et des nombreux ménages qui interagissent au sein des marchés des biens et services À première vue, le succès des économies de marché est déconcertant. Après tout, dans une économie de marché, personne ne considère le bien-être de la société dans son ensemble. Les marchés libres (ou décentralisés) présentent de nombreux acheteurs et vendeurs de nombreux biens et services et tous sont intéressés au premier titre par leur propre bien-être. Cependant, en dépit d’un processus de décision décentralisé et de décideurs égoïstes, les économies de marché s’avèrent remarquablement talentueuses dans l’organisation de l’activité économique, de manière à assurer le bien-être économique global. PouR VoTRE infoRmaTion Adam Smith et la main invisible Le célèbre ouvrage d’Adam Smith, La Riche sse de s Nations, fut publié en 1776 et constitue une référence fondamentale en économie. En soulignant le rôle de la main invisible dans les économies de marché, il reflète un point de vue propre aux auteurs des Lumières de la fin du dix-huitième siècle – l’idée selon laquelle les individus vont mieux lorsqu’ils sont livrés à euxmêmes et que la main lourde du gouvernement ne guide pas leur action. Cette philosophie politique fournit la base intellectuelle des économies de marché. Pourquoi les économies de marché fonctionnent-elles aussi bien ? Est-ce parce que l’on compte sur les individus pour traiter leur prochain avec amour et considération ? Pas du tout. Voici comment Adam Smith décrit la façon dont les individus interagissent dans des économies de marché : L’homme a presque continuellement besoin du secours de ses semblables, et c’est en vain qu’il l’attendrait de leur seule bienveillance. Il sera bien plus sûr de réussir, s’il s’adresse à leur intérêt personnel et s’il les persuade que leur propre avantage leur commande de faire ce qu’il souhaite d’eux. […] Ce n’est pas de la bienveillance du boucher, du marchand de bière et du boulanger, que nous attendons notre dîner, mais bien du soin qu’ils apportent à leurs intérêts. […] L’individu […] n’a pas du tout l’intention de promouvoir l’intérêt public pas plus qu’il n’a l’idée de la mesure dans laquelle il est en train d’y contribuer. […] Il ne pense qu’à son propre gain ; en cela, comme dans beaucoup Dix principes de l’économie 13 Dans un ouvrage datant de 1776, Recherches sur la nature et les causes de la richesse des nations, l’économiste écossais Adam Smith a fait une très célèbre observation en économie : les ménages et les firmes qui se rencontrent sur des marchés agissent comme s’ils étaient guidés par une « main invisible », qui les conduit à des situations désirables. Un de nos objectifs dans ce livre est de comprendre comment fonctionne la magie de la main invisible. En étudiant l’économie, vous apprendrez pourquoi les prix sont les instruments avec lesquels la main invisible dirige l’activité économique. Les prix reflètent à la fois la valeur que la société accorde à un bien et ce qu’il lui en coûte de produire ce bien. Puisque les ménages et les firmes se réfèrent au prix lorsqu’ils prennent leurs décisions d’achat et de vente, ils prennent en considération, sans le savoir, les avantages et les coûts sociaux relatifs à leurs actions. Finalement, les prix conduisent les décideurs individuels à des situations qui, dans de nombreux cas, maximisent le bien-être de la société dans son intégralité. 1.3.3 Principe 7 : L’État peut parfois améliorer les situations de marché Si la main invisible du marché est si merveilleuse, pourquoi alors avons-nous besoin de l’État ? Une réponse consisterait à dire que la main invisible a besoin de l’État pour la protéger. Les marchés ne fonctionnent que si les droits de propriété sont respectés. Un agriculteur ne produira pas de produits alimentaires s’il s’attend à ce que ses récoltes soient volées, et un restaurant ne servira pas de repas tant qu’il ne sera pas assuré que les clients paieront avant qu’ils ne partent. Nous nous reposons tous sur le contrôle public et sur les tribunaux pour assurer nos droits sur les choses que nous produisons. Une autre réponse à la même question de l’utilité de l’État trouve sa source dans le fait que, bien que les marchés soient habituellement un bon moyen de coordonner l’activité économique, cette règle connaît des exceptions importantes. En réalité, deux grandes raisons plaident pour qu’un État intervienne dans l’économie : la promotion de l’efficacité et la promotion de l’équité. Cela signifie que la plupart des politiques visent soit à augmenter la taille du gâteau économique, soit à changer la façon dont le gâteau est partagé. Bien que la main invisible conduise habituellement les marchés à allouer les ressources de manière efficace, cela n’est pas toujours le cas. Les économistes utilisent le mot d’autres cas, il est conduit par une main invisible à remplir une fin qui n’entre nullement dans ses intentions ; et ce n’est pas toujours ce qu’il y a de plus mal pour la société, que cette fin n’entre pour rien dans ses intentions. Tout en ne cherchant que son intérêt personnel, il travaille souvent d’une manière bien plus efficace pour l’intérêt de la société, que s’il avait réellement pour but d’y travailler. Smith affirme que les acteurs de l’économie sont motivés par la poursuite de leur intérêt individuel et que la « main invisible » oriente ces intérêts de façon à promouvoir le bien-être économique général. De nombreux apports de Smith sont au centre de l’économie moderne. Notre analyse, dans les chapitres suivants, nous permettra d’expliquer de manière plus précise les conclusions de Smith et d’examiner de plus près les forces et les faiblesses de la main invisible du marché. 14 introduction à l’économie défaillance (ou échec) de marché en référence à une situation dans laquelle le marché livré à lui-même ne réussit pas à produire une allocation des ressources efficace. Une cause possible d’échec de marché réside dans les externalités, qui mesurent l’impact sans contrepartie d’une action d’une personne sur le bien-être d’un tiers. L’exemple classique d’un coût externe est celui de la pollution. Une autre cause possible d’échec de marché est le pouvoir de marché qui fait référence à la capacité d’une personne seule (ou d’un petit groupe de personnes) à influencer outre mesure les prix de marché. Par exemple, si tous les habitants d’un village isolé des Highlands d’Écosse ont besoin d’eau et qu’il n’y a qu’un seul puits, le propriétaire du puits n’est pas soumis à la concurrence rigoureuse par laquelle la main invisible garde normalement l’intérêt individuel sous contrôle. En présence d’externalités ou de pouvoir de marché, une politique publique bien conçue peut augmenter l’efficacité économique. Ź Défaillance (ou échec) de marché une situation dans laquelle le marché décentralisé échoue à allouer les ressources de manière efficace Ź Externalité l’impact sans contrepartie des actions d’un individu sur le bien-être d’un tiers à l’échange Ź Pouvoir de marché la capacité d’un agent économique unique (ou d’un petit groupe d’agents) à exercer une influence substantielle sur les prix de marché La main invisible peut aussi échouer à garantir que la prospérité économique soit distribuée équitablement. Une économie de marché récompense les individus en fonction de leur capacité à produire des choses pour lesquelles d’autres individus sont prêts à payer. Le meilleur footballeur du monde gagne plus que le meilleur joueur d’échecs du monde simplement parce que les gens sont prêts à payer plus pour voir du football plutôt que des échecs. La main invisible ne garantit pas que tout individu disposera d’assez de nourriture, de vêtements décents et jouira d’une assurance santé adaptée. De nombreuses politiques publiques, telles que l’impôt sur le revenu et le système de sécurité sociale visent à obtenir une distribution plus équitable du bien-être économique. Dire que l’État est capable d’améliorer parfois les situations de marché ne signifie pas qu’il le fera systématiquement. La politique publique n’est pas faite par des anges et passe par des processus qui sont loin d’être parfaits. Quelquefois elle est le fait de dirigeants bien intentionnés mais qui ne sont pas parfaitement informés. Un objectif de l’étude de l’économie est de vous aider à juger si une politique publique est justifiée au regard de la promotion de l’efficacité ou de l’équité, ou bien si elle ne l’est pas. 1.4 comment FonctIonne L’ÉconomIe Dans son ensembLe Nous avons commencé en discutant de la façon selon laquelle les individus prennent leurs décisions puis nous avons observé comment ils interagissent les uns avec les autres. Dix principes de l’économie 15 L’ensemble de ces décisions et de ces interactions forme « l’économie ». Les trois derniers principes concernent le fonctionnement de l’économie dans son ensemble. 1.4.1 Microéconomie et macroéconomie L’analyse économique comporte plusieurs niveaux. Les sept premiers principes concernent le niveau individuel, ils étudient les décisions de ménages et des firmes ainsi que leurs interactions sur des marchés spécifiques. Les trois derniers principes que nous étudions portent sur le fonctionnement de l’économie dans son ensemble, il s’agit simplement de l’agrégation de toutes les activités de tous les décideurs sur tous les marchés. Depuis les années 1930, le champ de l’économie est traditionnellement divisé en deux grandes branches. La microéconomie est l’étude de la manière selon laquelle les ménages et les firmes prennent leurs décisions et interagissent sur des marchés particuliers. La macroéconomie est l’étude des phénomènes qui affectent l’économie dans sa globalité. Un microéconomiste pourrait étudier les effets d’une taxe sur le trafic sur l’utilisation des voitures dans le centre de Londres, l’impact de la concurrence étrangère sur l’industrie automobile européenne ou les effets des études universitaires sur les revenus que percevra un individu tout au long de sa vie. Un macroéconomiste pourrait étudier les effets de l’emprunt par les États nationaux, les variations du taux de chômage d’une économie dans le temps ou les politiques alternatives visant à faire progresser les niveaux de vie d’une nation. Ź microéconomie l’étude de la façon dont les ménages et les firmes prennent leurs décisions et interagissent au sein des marchés Ź macroéconomie l’étude de phénomènes économiques globaux incluant l’inflation, le chômage et la croissance économique Microéconomie et macroéconomie sont fortement liées. Comme les changements dans l’économie globale proviennent des décisions de millions d’individus, il est impossible de comprendre les développements macroéconomiques sans considérer les décisions microéconomiques impliquées. Par exemple, un microéconomiste pourrait étudier les effets de la diminution d’un impôt sur le revenu sur le niveau global de production de biens et services dans une économie. Pour analyser cette question, il doit considérer comment la réduction de la taxe affecte les décisions des ménages concernant le montant à dépenser en biens et services. Malgré le lien organique entre microéconomie et macroéconomie, les deux champs sont distincts. En économie, il semble en effet naturel de démarrer la construction sur la base de la plus petite unité. Or faire de la sorte n’est ni nécessairement ni toujours la meilleure façon de procéder. Comme la microéconomie et la macroéconomie traitent de questions différentes, elles adoptent parfois des approches très différentes et sont souvent enseignées dans des cours séparés. 16 introduction à l’économie Un concept clé de l’analyse économique est la croissance économique, elle mesure le taux d’augmentation (en %) de la quantité de biens et services dans une économie au cours d’une période, habituellement le trimestre ou l’année. Ź Croissance économique le taux d’augmentation de la quantité de biens et services d’une économie au cours d’une période 1.4.2 Principe 8 : Le niveau de vie d’une économie dépend de sa capacité à produire des biens et services Le tableau 1.1 montre le produit intérieur brut par tête dans un certain nombre de pays. Il est évident que de nombreux pays avancés présentent un revenu par tête relativement élevé ; il est de 39 160 dollars américains au Royaume-Uni, de 41 865 dollars en Allemagne et de 41 233 dollars en France. En Italie, le revenu moyen est légèrement inférieur à 33 115 dollars ; il est bien plus élevé en Suisse où il s’établit à 78 880 dollars, le Luxembourg culminant à 106 406 dollars. Ces valeurs sont à mettre en parallèle avec les performances nord-américaines, 52 299 dollars au Canada et 51 703 dollars aux États-Unis. Dès que l’on s’éloigne des économies prospères de l’Europe de l’Ouest et de l’Amérique du Nord, nous commençons à constater des écarts dans le revenu et le niveau de vie, au niveau mondial, qui sont renversants. Par exemple, cette même année 2012, le revenu moyen du Gabon, 11 942 dollars, s’établissait à la moitié du revenu grec, en Bolivie il était seulement de 2 514 dollars, en Inde 1 500 dollars et en Haiti 758 dollars – soit un peu moins de 0,7 pour cent du revenu moyen par personne au Luxembourg ! Il n’est pas surprenant que cette grande variation dans le revenu moyen se reflète dans les autres mesures de la qualité et du niveau de la vie. Les citoyens des pays à hauts revenus bénéficient d’une meilleure alimentation, d’un meilleur système de santé et d’une espérance de vie plus longue que les citoyens des pays à bas revenus, et ils disposent aussi de plus de téléviseurs, d’enregistreurs numériques et de voitures. Les variations dans le niveau de vie au cours du temps sont aussi importantes. Au cours des 5 dernières années, l’Albanie a connu une croissance économique de 4,68 % par an, contre 10,5 % par an en Chine, alors qu’en Lettonie, le PIB a baissé de 1,4 % sur la même période (source : Banque Mondiale). Ź niveau de vie la quantité de biens et services qui peuvent être achetés par la population d’un pays. Il est habituellement mesuré par le revenu réel (ajusté par l’inflation) par habitant Qu’est-ce qui explique ces différences importantes dans les niveaux de vie entre les pays et au cours du temps ? De manière surprenante, la réponse est simple. Presque tout l’écart de niveau de vie est attribuable aux différences de productivité des pays – c’està-dire la quantité de biens et services produits par chaque heure de travail. Dans les nations où les travailleurs sont capables de produire une grande quantité de biens et services par Dix principes de l’économie 17 unité de temps, la plupart des citoyens bénéficient d’un niveau de vie élevé, dans les nations où les travailleurs sont moins productifs, la plupart des citoyens connaissent des conditions de vie plus modestes. De manière similaire, le taux de croissance de la productivité d’une nation détermine le taux de croissance de son revenu moyen. Ź Productivité la quantité de biens et services produite en une heure par un travailleur tableau 1.1 Produit Intérieur Brut par tête, prix courants, dollars US 2009 Pays PIb par tête Afghanistan 633 Allemagne 41 865 Autriche 46 642 Belgique 43 615 Bénin 752 Bolivie 2 514 Burundi 281 Cameroun 1 181 Canada 52 299 Chine 6 071 Côte d'Ivoire 1 057 Danemark 56 426 Finlande 45 634 France 41 223 Gabon 11 942 Grèce 22 072 Guinée 518 Haiti 758 Inde 1 500 Italie 33 115 Japon 46 706 Luxembourg 106 406 Maroc 2 955 Norvège 99 170 République démocratique du Congo 230 République Dominicaine 5 766 Royaume-Uni 39 160 Russie 14 302 Singapour 52 051 Suisse 78 880 Tunisie 4 213 Turquie 10 526 USA 51 703 Vietnam 1 752 Yemen 1 366 Zimbabwe 755 Source : Fonds Monétaire International, base de données World Economic Outlook, octobre 2013 18 introduction à l’économie Cette relation fondamentale entre productivité et niveau de vie est simple, mais ses implications sont vastes. Si la productivité est le déterminant premier des niveaux de vie, d’autres explications sont nécessairement secondaires. Par exemple, il serait tentant de porter au crédit des syndicats de travailleurs ou des lois sur le salaire minimum l’augmentation des niveaux de vie des travailleurs européens au cours des 50 dernières années. En fait, le véritable héros des travailleurs européens est leur productivité croissante. La relation entre productivité et niveau de vie a aussi des implications considérables pour la politique publique. Lorsque l’on pense à la façon dont une politique affecte les niveaux de vie, la question clé est de savoir comment elle affectera notre capacité à produire des biens et des services. Afin de doper les niveaux de vie, les décideurs politiques doivent faire augmenter la productivité en s’assurant que les travailleurs ont un bon niveau d’instruction, qu’ils ont les outils nécessaires pour produire des biens et services et qu’ils ont accès à la meilleure technologie disponible. 1.4.3 Principe 9 : Les prix augmentent lorsque la Banque centrale imprime trop de monnaie Ź inflation l’augmentation du niveau général des prix de l’économie Au Zimbabwe en mars 2007, il y avait à peu près 2 200 pour cent d’inflation. Cela signifie qu’un bien qui valait 2,99 euros en mars 2006 avait un prix de 65,78 euros à peine un an après. En février 2008, l’inflation se montait à 165 000 %. Cinq mois plus tard, elle culminait à 2 200 000 %. En juillet 2008, la banque centrale a imprimé un billet de 100 milliards zimbabwéens. À ce moment-là, il était à peine suffisant pour acheter une miche de pain. Des prévisions d’inflation en juillet 2008 ont fixé le taux de croissance des prix à 231 millions de pour cent. En janvier 2009, la banque centrale zimbabwéenne a émis des billets de 10, 20, 50 et 100 mille milliards de dollars – 100 trillions valant le nombre 100 suivi de 12 zéros. Comme l’inflation impose différents coût s à la société, garder l’inflation à un bas niveau est un objectif pour tous ceux qui font de la politique économique. Qu’est-ce qui est à l’origine de l’inflation ? Dans presque tous les cas d’inflation forte ou persistante, le coupable est le même : la croissance dans la quantité de monnaie. Lorsqu’une banque centrale émet de larges quantités de la monnaie nationale, la valeur de la monnaie baisse. Il est aussi largement accepté qu’il existe un lien entre la croissance monétaire et l’inflation. 1.4.4 Principe 10 : À court terme, la société est confrontée à un arbitrage entre inflation et chômage Lorsque la banque centrale fait augmenter la quantité de monnaie dans l’économie, une des conséquences est l’inflation. Une autre conséquence, au moins à court terme, est un niveau de chômage plus faible. La courbe qui illustre cet arbitrage à court terme entre inflation et chômage s’appelle la courbe de Phillips, du nom de l’économiste qui l’a étudiée en premier alors qu’il travaillait à la London School of Economics. Dix principes de l’économie 19 Ź Courbe de Phillips la courbe qui montre l’arbitrage de court terme entre l’inflation et le chômage La courbe de Phillips reste un sujet controversé parmi les économistes, bien que la plupart d’entre eux acceptent aujourd’hui l’idée qu’il existe à court terme un arbitrage entre l’inflation et le chômage. Cela signifie simplement qu’au cours d’une période d’un an ou deux, de nombreuses politiques économiques poussent l’inflation et le chômage dans des directions opposées. Les décideurs politiques sont confrontés à cet arbitrage, que les niveaux d’inflation ou de chômage d’origine soient tous deux élevés (comme ils l’étaient au début des années 1980) ou faibles (comme à la fin des années 1990), ou encore qu’ils se situent quelque part entre ces deux extrêmes. L’arbitrage entre l’inflation et le chômage est seulement temporaire, mais il peut aussi durer plusieurs années. La courbe de Phillips est, par conséquent, essentielle à la compréhension de nombreux développements de l’économie. En particulier, elle est importante pour la compréhension du cyc le économique – les fluctuations irrégulières et largement imprévisibles dans l’activité économique, telles qu’elles apparaissent dans le nombre de personnes employées ou dans la production de biens et services. Ź Cycle économique les fluctuations de l’activité économique, comme celles de l’emploi et de la production Les décideurs politiques peuvent exploiter l’arbitrage de court terme entre inflation et chômage en utilisant différents instruments de politique économique. En modifiant les montants que l’État dépense, ceux qu’il taxe et la quantité de monnaie qu’il imprime, les décideurs politiques peuvent influencer la combinaison d’inflation et de chômage que connaît l’économie. Comme ces instruments de politique monétaire et de politique budgétaire sont potentiellement si puissants, la question de savoir comment les décideurs politiques devraient les utiliser pour contrôler l’économie, fait l’objet d’un débat permanent.

Listez trois questions qui relèvent de la microéconomie et trois questions qui relèvent de la macroéconomie. concLusIon Vous avez pu entrevoir ce sur quoi porte l’économie. Dans les chapitres à venir, nous développerons de nombreuses idées caractéristiques des individus, des marchés et des économies. Maîtriser ces idées vous demandera des efforts, mais ce n’est pas une tâche écrasante. Le champ de l’économie développe quelques idées de base qui peuvent être appliquées à un grand nombre de situations différentes. 20 introduction à l’économie Tout au long de ce livre, nous continuerons à nous référer aux Dix pr incipe s de l’économie introduits dans ce chapitre et résumés dans le tableau 1.2. Vous devriez garder présents à votre esprit ces éléments fondateurs. Toute analyse économique, même la plus sophistiquée, est élaborée en référence à ces dix principes. tableau 1.2 Dix principes de l’économie Comment les individus prennent leurs décisions 1. Les individus font face à des arbitrages. 2. Le coût d’une chose mesure ce à quoi on renonce pour l’obtenir. 3. Les individus rationnels raisonnent à la marge. 4. Les individus réagissent aux incitations. Comment les individus interagissent 5. L’échange est profitable pour tous. 6. Les économies de marché sont habituellement un bon mode d’organisation de l’activité économique. 7. L’État peut parfois améliorer les situations de marché. Comment fonctionne l’économie dans son ensemble 8. Le niveau de vie d’une économie dépend de sa capacité à produire des biens et services. 9. Les prix augmentent lorsque la banque centrale imprime trop de monnaie. 10. À court terme, la société est confrontée à un arbitrage entre inflation et chômage. Dans L’aCTuaLiTÉ Pensée récente en économie – les incitations Un des Dix pr incipe s de l’économie stipule que les individus réagissent aux incitations. Cela ne paraît pas à première vue surprenant, mais illustre bien le fait que les économistes peuvent tirer d’un lieu commun une réflexion plus complexe. Gneezy et al . montrent que la complexité de la nature humaine rend la question des incitations un vrai défi à la réflexion (Gneezy, U., Meier, S. et P. Ray-Biel (2011) « Quand et pourquoi les incitations (ne) parviennent (pas) à modifier les comportements » Jour nal of Economic Perspe ctives 25 : 4, pp. 191-210). Ces auteurs montrent que les incitations fonctionnent dans certaines conditions seulement et ils concluent que les décideurs politiques doivent prendre en compte une diversité de situations possibles lorsqu’ils mettent en place ces incitations. Ils doivent tout d’abord s’intéresser au type de comportement qui doit être changé. Par exemple, selon Gneezy et al . une société pourrait encourager ses citoyens à se comporter de manière davantage « pro-sociale », c’est-à-dire développer le don de sang, de sperme ou d’organes, le recyclage des déchets, l’assiduité et le sens de l’effort à l’école, l’installation de panneaux solaires afin de réduire la consommation d’électricité, ou encore diminuer la consommation de tabac. Ensuite, il faut identifier les parties prenantes à ces initiatives. Cela peut s’assimiler à un problème de principal-agent. Le principal est une personne, ou un groupe de personnes, pour le compte de laquelle, une autre personne ou groupe de personnes, (l’agent), agit. Dans l’exemple de la lutte contre le tabac, la société est le principal et l’agent est le groupe de fumeurs. Dix principes de l’économie 21 Il faut alors déterminer le type d’incitations mises en place – elles sont en général de nature monétaire. Les incitations monétaires ont deux effets principaux détaillés par Gneezy et al . : l’effet-prix direct et l’effet psychologique. Une fois que tous ces éléments ont été identifiés, le comportement à changer, le principal, l’agent et le type d’incitations, il faut passer à l’étape suivante, la définition du schéma d’incitations. Une première solution possible est plutôt simple : mettre en place une incitation monétaire, c’est-à-dire payer les gens pour qu’ils se comportent comme prévu. La question est de savoir si cela va fonctionner. Gneezy et al. dénombrent des raisons pour lesquelles le résultat peut ne pas être conforme aux attentes. Dans certains cas, les incitations monétaires peuvent « évincer » le comportement attendu. Donner de l’argent pour inciter les gens à donner de leur sang ou aller régulièrement à l’école peut ne pas produire les effets escomptés car cela change la perception des individus. En effet, ces derniers ont des motivations propres, des raisons personnelles de faire des choses. D’autres sont sensibles à l’avis d’autrui et donnent leur sang pour gagner en estime sociale. Selon Gneezy, l’échec des incitations monétaires peut s’expliquer par le fait que l’effet psychologique l’emporte sur l’effet prix. Comment ? Certains individus qui donnent de leur sang par conviction personnelle pourraient finalement ne plus continuer à le faire, au motif que, aux yeux de la société ils ne seraient finalement plus motivés que par l’appât du gain. Ainsi, dans le cas où l’effet psychologique l’emporte sur l’effet prix direct, le nombre de donneurs pourrait diminuer. En ce qui concerne la lutte contre le tabac, l’impact financier peut être un facteur déterminant. Le principe 5 des Dix pr incipe s de l’économie stipule que les individus raisonnent à la marge. La décision de fumer une cigarette supplémentaire induit des avantages et des coût s – le plaisir de fumer contre la réduction de la durée de vie (estimée à 11 minutes) du fumeur. Le problème provient du fait que le coût ne se fait pas ressentir au moment même où la cigarette est fumée (sans compter le risque d’addiction) et l’avantage marginal l’emporte. À long terme, les avantages liés à l’arrêt de la consommation de tabac deviennent bien plus importants que le coût total. L’incitation offerte doit alors être conçue au regard de ce raisonnement marginal, ce qui peut être une tâche difficile. D’autres questions relatives aux incitations renvoient à la confiance mutuelle entre le principal et l’agent. La mise en place d’une incitation envoie le message selon lequel le comportement attendu n’est pas effectif et qu’il doit y avoir une raison pour cela. Les incitations véhiculent aussi l’idée que le principal n’est pas persuadé de la motivation intrinsèque de l’agent (ex. les gens ne donneront pas leur sang, les déchets ne seront pas recyclés…) . De plus, si les incitations parviennent à faire changer les comportements à court terme, cela sera-t-il toujours le cas à long terme, une fois que l’incitation est retirée ? Enfin, le succès des incitations peut dépendre de la manière dont elles sont libellées ou bien présentées par le principal à l’agent. Gneezy et al . présentent un exemple très intéressant. Imaginez, disent-ils, une situation dans laquelle vous rencontrez une personne avec qui vous engagez une relation. Vous souhaitez l’inciter à aller plus loin et avoir des relations plus poussées. La manière de procéder peut avoir un impact considérable sur le résultat. Si par exemple, vous formulez votre « offre » de la manière suivante « je veux faire l’amour avec toi et pour t’y inciter je te donne 50 euros » alors vous pourriez obtenir un résultat très différent comparé à la situation dans laquelle vous dites « je veux faire l’amour avec toi – je t’ai acheté un bouquet de roses rouges [qui d’ailleurs coût ent 50 euros]. L’efficacité des incitations doit être aussi évaluée au regard de leur coût . Les autorités sanitaires dépensent des millions d’euros en Europe au titre de médicaments contre l’hypertension et le cholestérol. Faire en sorte que les gens fassent davantage d’exercice pourrait conduire au même résultat. Qu’est-ce qui pourrait être moins coût eux et plus efficace en termes d’allocation 22 introduction à l’économie PouR VoTRE infoRmaTion Comment lire ce livre L’étude de l’économie est plaisante, mais elle peut aussi être difficile. Notre objectif en écrivant ce manuel a été de le rendre aussi abordable et plaisant que possible. Mais vous, en tant qu’étudiant, vous avez aussi votre rôle à jouer.

À la fin de chaque chapitre, la rubrique « Questions pour réviser » teste votre compréhension, puis « Problèmes et applications » vous demande d’appliquer et d’aller plus loin. Il est possible que votre professeur vous demande de faire certains exercices dans le cadre de devoirs. Si c’est le cas, faites-les. Si ce n’est pas le cas, faites-les quand même. Plus vous utilisez votre nouveau savoir, plus il devient solide. 4. Trav ai llez en gr oupe . Après avoir lu le livre et travaillé les problèmes de votre côté, réunissezvous avec d’autres étudiants pour en discuter le contenu. Vous apprendrez les uns des autres – c eci est une illustration des gains à l’échange. QuEsTions 1. Pourquoi les gens ont-ils besoin d’incitations pour faire des « bonnes » choses, comme donner leur sang ou recycler les déchets ? 2. Qu’est-ce qu’un problème « principal-agent » ? 3. Quels seraient l’effet-prix et l’effet psychologique d’une incitation monétaire destinée à des étudiants afin qu’ils obtiennent de très bonnes notes à l’université ? 4. En quoi est-ce que la mesure de l’incitation est un facteur déterminant dans l’atteinte du comportement désiré ? Quels pourraient être les effets collatéraux dans le cas où cette incitation est renforcée ? 5. En quoi la formulation d’une incitation contribue à l’atteinte du résultat escompté ? Prenez le cas du don d’organes pour répondre à la question. des ressources ? Inciter les gens à faire plus de sport en subventionnant une partie de l’abonnement à la salle de gym ou bien dépenser des fortunes en médicaments sans se préoccuper de la cause de ces problèmes de santé ? Dix principes de l’économie 23 RÉsumÉ 1. Les leçons fondamentales relatives à la formation des décisions individuelles sont que les individus font face à des arbitrages entre des objectifs alternatifs, que le coût de n’importe quelle action est mesuré en termes d’opportunités sacrifiées, que les individus rationnels prennent leurs décisions en comparant les coûts marginaux et les avantages marginaux et qu’ils changent de comportement en réaction aux incitations auxquels ils sont confrontés. 2. Les leçons fondamentales relatives aux interactions entre individus sont que les échanges peuvent être mutuellement bénéfiques, que les marchés sont habituellement un bon moyen de coordonner les échanges entre les individus et que l’État peut potentiellement améliorer les situations de marché s’il y a des échecs de marché ou si la situation est inéquitable. 3. L’analyse économique comporte deux branches : la microéconomie et la macroéconomie. Les microéconomistes étudient la manière dont les ménages et les firmes prennent leurs décisions et comment ils interagissent sur les différents marchés. Les macroéconomistes étudient les forces et les tendances au niveau de l’économie dans son ensemble. 4. Les leçons fondamentales relatives à l’économie dans son ensemble sont que la productivité est la source fondamentale des niveaux de vie, que la croissance de la monnaie est la source fondamentale de l’inflation et que la société est confrontée à un arbitrage de court terme entre l’inflation et le chômage. QuEsTions PouR RÉVisER 1. Donnez trois exemples d’arbitrage que vous rencontrez dans votre vie. 2. Quel est le coût d’opportunité lié au fait d’aller manger au restaurant ? 3. L’eau est nécessaire à la vie. L’avantage marginal d’un verre d’eau est-il grand ou petit ? 4. Pourquoi les décideurs politiques doivent-ils penser aux incitations ? 5. Pourquoi l’échange n’est-il pas comme un jeu, avec des gagnants et des perdants ? 5. N’oubl iez pas le monde réel. Au milieu de tous les nombres, graphiques et nouveaux mots étranges, il est facile de perdre de vue ce qu’est vraiment l’économie. Les encarts « Études de cas » et « Dans l’actualité », disséminés un peu partout dans le livre, devraient vous aider à vous en souvenir. Ne les ignorez pas. Ils montrent comment la théorie est liée aux événements qui arrivent dans nos vies. La rubrique « Dans l’actualité » vous permettra de revenir sur les questions traitées dans le chapitre et de les mettre en application dans des situations particulières. Tenter de répondre à toutes ces questions vous permettra de renforcer votre compréhension.

Franck Jovanovic est professeur de finance à l’Université de Leicester. Il a acquis une expertise dans la création de cours en ligne basés sur les nouvelles technologies lorsqu’il était en poste à la TELUQ - l’Université à distance et en ligne du Québec. Il a développé une expertise pédagogique à travers les postes et responsabilités qu’il a occupés dans des universités en France, au Canada, en Côte d’Ivoire et en Grande-Bretagne (incluant HEC Montréal, l’UQAM, l’Université York, l’Université Paris 1 - Panthéon-Sorbonne, l’Université d’Angers, l’Université d’Orléans, l’Institut Universitaire d’Abidjan), et conseille aujourd’hui des universités sur l’intégration de nouvelles technologies et pratiques pédagogiques dans leurs cours. Ses recherches portent sur l’économie financière, ses fondements, son influence sur les marchés financiers, et ses liens avec l’éconophysique. Ses travaux ont été publiés dans de nombreuses revues académiques et ouvrages. Il a également été consultant ou analyste pour l’OCDE, l’Agence Française de Développement et le Ministère français de l’Économie et des Finances, et pour des organisations professionnelles (comme la compagnie nationale des commissaires aux comptes ou la Fédération Française de la Franchise). Ils comportent : • Plus d’une centaine d’animations avec voix off, facilitant l’apprentissage. Ils incluent près de 600 graphiques, figures et tableaux en complément de ceux du manuel. Ils incluent également plus de 400 questions avec leurs réponses détaillées. Ces questions permettent aux étudiants de tester au cours de leur lecture leur compréhension et maîtrise des connaissances étudiées et d’appliquer les concepts à des cas réels. • 7 outils de simulation interactifs permettant d’appliquer les concepts étudiés avec des exemples concrets et de visualiser les effets des politiques publiques et monétaires sur l’activité économique d’un pays. Ces outils offrent une interface conviviale et facile d’utilisation. • 162 exercices et problèmes avec pour chacun un solutionnaire détaillé. En outre, 85 exercices sont corrigés à l’aide de vidéos permettant de visualiser la manière dont un économiste pose et résout ces types d’exercices. • Des rappels mathématiques et méthodologiques pour rappeler les notions de base utilisées dans le manuel.

We not only look at things to identify and classify them, but we can scan for differences, and obtain an overall rough “feeling” for a scene with a quick glance. Humans have evolved very precise visual skills: we can identify a face in an instant; we can differentiate colours; we can process a large amount of visual information very quickly. However, the world is in constant motion: stare at something for long enough and it will change in some way. Even a large solid structure, like a building or a mountain, will change its appearance depending on the time of day (day or night); amount of sunlight (clear or cloudy), or various shadows falling upon it. We are concerned with single images: snapshots, if you like, of a visual scene. Although image processing can deal with changing scenes, we shall not discuss it in any detail in this text. For our purposes, an image is a single picture which represents something. It may be a picture of a person, of people or animals, or of an outdoor scene, or a microphotograph of an electronic component, or the result of medical imaging. Even if the picture is not immediately recognizable, it will not be just a random blur. 1.2 What is image processing? Image processing involves changing the nature of an image in order to either 1. improve its pictorial information for human interpretation, 2. render it more suitable for autonomous machine perception. We shall be concerned with digital image processing, which involves using a computer to change the nature of a digital image (see below). It is necessary to realize that these two aspects represent two separate but equally important aspects of image processing. A procedure which satisfies condition (1)—a procedure which makes an image “look better”—may be the very worst procedure for satisfying condition (2). Humans like their images to be sharp, clear and detailed; machines prefer their images to be simple and uncluttered. Examples of (1) may include: 1 2 CHAPTER 1. INTRODUCTION Enhancing the edges of an image to make it appear sharper; an example is shown in figure 1.1. Note how the second image appears “cleaner”; it is a more pleasant image. Sharpening edges is a vital component of printing: in order for an image to appear “at its best” on the printed page; some sharpening is usually performed. (a) The original image (b) Result after “sharperning” Figure 1.1: Image sharperning Removing “noise” from an image; noise being random errors in the image. An example is given in figure 1.2. Noise is a very common problem in data transmission: all sorts of electronic components may affect data passing through them, and the results may be undesirable. As we shall see in chapter 7 noise may take many different forms;each type of noise requiring a different method of removal. Removing motion blur from an image. An example is given in figure 1.3. Note that in the deblurred image (b) it is easy to read the numberplate, and to see the spokes on the wheels of the car, as well as other details not at all clear in the original image (a). Motion blur may occur when the shutter speed of the camera is too long for the speed of the object. In photographs of fast moving objects: athletes, vehicles for example, the problem of blur may be considerable. Examples of (2) may include: Obtaining the edges of an image. This may be necessary for the measurement of objects in an image; an example is shown in figures 1.4. Once we have the edges we can measure their spread, and the area contained within them. We can also use edge detection algorithms as a first step in edge enhancement, as we saw ab 1.2. WHAT IS IMAGE PROCESSING? 3 (a) The original image (b) After removing noise Figure 1.2: Removing noise from an image (a) The original image (b) After removing the blur Figure 1.3: Image deblurring 4 CHAPTER 1. INTRODUCTION From the edge result, we see that it may be necessary to enhance the original image slightly, to make the edges clearer. (a) The original image (b) Its edge image Figure 1.4: Finding edges in an image Removing detail from an image. For measurement or counting purposes, we may not be interested in all the detail in an image. For example, a machine inspected items on an assembly line, the only matters of interest may be shape, size or colour. For such cases, we might want to simplify the image. Figure 1.5 shows an example: in image (a) is a picture of an African buffalo, and image (b) shows a blurred version in which extraneous detail (like the logs of wood in the background) have been removed. Notice that in image (b) all the fine detail is gone; what remains is the coarse structure of the image. We could for example, measure ther size and shape of the animal without being “distracted” by unnecessary detail. 1.3 Images and digital images Suppose we take an image, a photo, say. For the moment, lets make things easy and suppose the photo is black and white (that is, lots of shades of grey), so no colour. We may consider this image as being a two dimensional function, where the function values give the brightness of the image at any given point, as shown in figure 1.6. We may assume that in such an image brightness values can be any real numbers in the range  (black) to   (white). The ranges of  and  will clearly depend on the image, but they can take all real values between their minima and maxima. A digital image differs from a photo in that the , , and     values are all discrete. Usually they take on only integer values, so the image shown in figure 1.6 will have  and  ranging from 1 to 256 each, and the brightness values also ranging from 0 (black) to 255 (white). A digital image can be considered as a large array of discrete dots, each of which has a brightness associated with it. These dots are called picture elements, or more simply pixels. The pixels surrounding a given pixel constitute its neighbourhood. A neighbourhood can be characterized by its shape in the same way as a matrix: we can speak of a  neighbourhood, or of a  neighbourhood. Except in very special circumstances, neighbourhoods have odd numbers of rows and columns; this ensures that the current pixel is in the centre of the neighbourhood. An example of a neighbourhoo 1.3.

Here is a short list just to give some indication of the range of image processing applications. 1. Medicine Inspection and interpretation of images obtained from X-rays, MRI or CAT scans, analysis of cell images, of chromosome karyotypes. 2. Agriculture Satellite/aerial views of land, for example to determine how much land is being used for different purposes, or to investigate the suitability of different regions for different crops, inspection of fruit and vegetables—distinguishing good and fresh produce from old. 3. Industry Automatic inspection of items on a production line, inspection of paper samples. 4. Law enforcement Fingerprint analysis, sharpening or de-blurring of speed-camera 1.5. ASPECTS OF IMAGE PROCESSING 7 1.5 Aspects of image processing It is convenient to subdivide different image processing algorithms into broad subclasses. There are different algorithms for different tasks and problems, and often we would like to distinguish the nature of the task at hand. Image enhancement. This refers to processing an image so that the result is more suitable for a particular application. Example include: sharpening or de-blurring an out of focus image, highlighting edges, improving image contrast, or brightening an image, removing noise. Image restoration. This may be considered as reversing the damage done to an image by a known cause, for example: removing of blur caused by linear motion, removal of optical distortions, removing periodic interference. Image segmentation. This involves subdividing an image into constituent parts, or isolating certain aspects of an image: finding lines, circles, or particular shapes in an image, in an aerial photograph, identifying cars, trees, buildings, or roads. These classes are not disjoint; a given algorithm may be used for both image enhancement or for image restoration. However, we should be able to decide what it is that we are trying to do with our image: simply make it look better (enhancement), or removing damage (restoration). 1.6 An image processing task We will look in some detail at a particular real-world task, and see how the above classes may be used to describe the various stages in performing this task. The job is to obtain, by an automatic process, the postcodes from envelopes. Here is how this may be accomplished: Acquiring the image. First we need to produce a digital image from a paper envelope. This an be done using either a CCD camera, or a scanner. Preprocessing. This is the step taken before the “major” image processing task. The problem here is to perform some basic tasks in order to render the resulting image more suitable for the job to follow. In this case it may involve enhancing the contrast, removing noise, or identifying regions likely to contain the postcode. Segmentation. Here is where we actually “get” the postcode; in other words we extract from the image that part of it which contains just the 8 CHAPTER 1. INTRODUCTION Representation and description. These terms refer to extracting the particular features which allow us to differentiate between objects. Here we will be looking for curves, holes and corners which allow us to distinguish the different digits which constitute a postcode. Recognition and interpretation. This means assigning labels to objects based on their descriptors (from the previous step), and assigning meanings to those labels. So we identify particular digits, and we interpret a string of four digits at the end of the address as the postcode. 1.7 Types of digital images We shall consider four basic types of images: Binary. Each pixel is just black or white. Since there are only two possible values for each pixel, we only need one bit per pixel. Such images can therefore be very efficient in terms of storage. Images for which a binary representation may be suitable include text (printed or handwriting), fingerprints, or architectural plans. An example was the image shown in figure 1.4(b) above. In this image, we have only the two colours: white for the edges, and black for the background. See figure 1.8 below. 1 1 0 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 0 1 0 0 0 0 0 1 1 0 0 0 0 0 0 1 Figure 1.8: A binary image Greyscale. Each pixel is a shade of grey, normally from (black) to   (white). This range means that each pixel can be represented by eight bits, or exactly one byte. This is a very natural range for image file handling. Other greyscale ranges are used, but generally they are a power of 2. Such images arise in medicine (X-rays), images of printed works, and indeed  different grey levels is sufficient for the recognition of most natural objects. An example is the street scene shown in figure 1.1 above, and in figure 1.9 bel 1.7.

Here each pixel has a particular colour; that colour being described by the amount of red, green and blue in it. If each of these components has a range –  , this gives a total of        different possible colours in the image. This is enough colours for any image. Since the total number of bits required for each pixel is , such images are also called -bit colour images. Such an image may be considered as consisting of a “stack” of three matrices; representing the red, green and blue values for each pixel. This measn that for every pixel there correspond three values. We show an example in figure 1.10. Indexed. Most colour images only have a small subset of the more than sixteen million possible colours. For convenience of storage and file handling, the image has an associated colour map, or colour palette, which is simply a list of all the colours used in that image. Each pixel has a value which does not give its colour (as for an RGB image), but an index to the colour in the map. It is convenient if an image has  colours or less, for then the index values will only require one byte each to store. Some image file formats (for example, Compuserve GIF), allow only  colours or fewer in each image, for precisely this reason. Figure 1.11 shows an example. In this image the indices, rather then being the grey values of the pixels, are simply indices into the colour map. Without the colour map, the image would be very dark and colourless. In the figure, for example, pixels labelled 5 cor 10 CHAPTER 1.

Indices Colour map Figure 1.11: An indexed colour image 1.8 Image File Sizes Image files tend to be large. We shall investigate the amount of information used in different image type of varying sizes. For example, suppose we consider a    binary image. The number of bits used in this image (assuming no compression, and neglecting, for the sake of discussion, any header information) is           bytes    Kb   Mb. (Here we use the convention that a kilobyte is one thousand bytes, and a megabyte is one million bytes.) A greyscale image of the same size requires:         bytes    Kb   Mb. If we now turn our attention to colour images, each pixel is associated with 3 bytes of colour information. A   image thus requires  12 CHAPTER 1. INTRODUCTION     Kb    Mb. Many images are of course such larger than this; satellite images may be of the order of several thousand pixels in each direction. “A picture is worth one thousand words” Assuming a word to contain 10 ASCII characters (on average), and that each character requires 8 bits of storage, then 1000 words contain     bits of information. This is roughly equivalent to the information in a   binary image    greyscale image    RGB colour image. 1.9 Image Acquisition We will briefly discuss means for getting a picture “into” a computer. CCD camera. Such a camera has, in place of the usual film, an array of photosites; these are silicon electronic devices whose voltage output is proportional to the intensity of light falling on them. For a camera attached to a computer, information from the photosites is then output to a suitable storage medium. Generally this is done on hardware, as being much faster and more efficient than software, using a frame-grabbing card. This allows a large number of images to be captured in a very short time—in the order of one ten-thousandth of a second each. The images can then be copied onto a permanent storage device at some later time. Digital still cameras use a range of devices, from floppy discs and CD’s, to various specialized cards and “memory sticks”. The information can then be downloaded from these devices to a computer hard disk. Flat bed scanner. This works on a principle similar to the CCD camera. Instead of the entire image being captured at once on a large array, a single row of photosites is moved across the image, capturing it row-by-row as it moves. Since this is a much slower process than taking a picture with a camera, it is quite reasonable to allow all capture and storage to be processed by suitable software. 1.10 Image perception Much of image processing is concerned with making an image appear “better” to human beings. We should therefore be aware of the limitations of the the human visual system. Image perception consists of two basic steps: 1. capturing the i 1.10. IMAGE PERCEPTION 13 2. recognising and interpreting the image with the visual cortex in the brain. The combination and immense variability of these steps influences the ways in we perceive the world around us. There are a number of things to bear in mind: 1. Observed intensities vary as to the background. A single block of grey will appear darker if placed on a white background than if it were placed on a black background. That is, we don’t perceive grey scales “as they are”, but rather as they differ from their surroundings. In figure 1.12 a grey square is shown on two different backgrounds. Notice how much darker the square appears when it is surrounded by a light grey. However, the two central squares have exactly the same intensity. Figure 1.12: A grey square on different backgrounds 2. We may observe non-existent intensities as bars in continuously varying grey levels. See for example figure 1.13. This image varies continuously from light to dark as we travel from left to right. However, it is impossible for our eyes not to see a few horizontal edges in this image. 3. Our visual system tends to undershoot or overshoot around the boundary of regions of different intensities. For example, suppose we had a light grey blob on a dark grey background. As our eye travels from the dark background to the light region, the boundary of the region appears lighter than the rest of it. Conversely, going in the other direction, the boundary of the background appears darker than the rest of it. 14 CHAPTER 1. INTRODUCTION Figure 1.13: Continuously varying intensities Chapter 2 Basic use of Matlab 2.1 Introduction Matlab is a data analysis and visualization tool which has been designed with powerful support for matrices and matrix operations. As well as this, Matlab has excellent graphics capabilities, and its own powerful programming language. One of the reasons that Matlab has become such an important tool is through the use of sets of Matlab programs designed to support a particular task. These sets of programs are called toolboxes, and the particular toolbox of interest to us is the image processing toolbox. Rather than give a description of all of Matlab’s capabilities, we shall restrict ourselves to just those aspects concerned with handling of images. We shall introduce functions, commands and techniques as required. A Matlab function is a keyword which accepts various parameters, and produces some sort of output: for example a matrix, a string, a graph or figure. Examples of such functions are sin, imread, imclose. There are manyfunctions in Matlab, and as we shall see, it is very easy (and sometimes necessary) to write our own. A command is a particular use of a function. Examples of commands might be >> sin(pi/3) >> c=imread(’cameraman.tif’); >> a=imclose(b); As we shall see, we can combine functions and commands, or put multiple commnds on a single input line. Matlab’s standard data type is the matrix—all data are considered to be matrices of some sort. Images, of course, are matrices whose elements are the grey values (or possibly the RGB values) of its pixels. Single values are considered by Matlab to be    matrices, while a string is merely a   matrix of characters; being the string’s length. In this chapter we will look at the more generic Matlab commands, and discuss images in further chapters. When you start up Matlab, you have a blank window called the “Command Window” in which you enter commands. This is shown in figure 2.1. Given the vast number of Matlab’s functions, and the different parameters they can take, a command line style interface is in fact much more efficient than a complex sequence of pull-down menus. The prompt consists of two right arrows: >> 16 CHAPTER 2. BASIC USE OF MATLAB Figure 2.1: The Matlab command window ready for action 2.2 Basic use of Matlab If you have never used Matlab before, we will experiment with some simple calculations. We first note that Matlab is command line driven; all commands are entered by typing them after the prompt symbol. Let’s start off with a mathematical classic: >> 2+2 What this means is that you type in 2 at the prompt, and then press your Enter key. This sends the command to the Matlab kernel. What you should now see is ans = 4 Good, huh? Matlab of course can be used as a calculator; it understands the standard arithmetic operations of addition (as we have just seen), subtraction, multiplication, division and exponentiation. Try these: >> 3*4 >> 7-3 >> 11/7 2.3. VARIABLES AND THE WORKSPACE 17 >> 2^5 The results should not surprise you. Note that for the output of 11/7 the result was only given to a few decimal places. In fact Matlab does all its calculations internally to double precision. However, the default display format is to use only eight decimal places. We can change this by using the format function. For example: >> format long >> 11/7 ans = 1.57142857142857 Entering the command format by itself returns to the default format. Matlab has all the elementary mathematical functions built in: >> sqrt(2) ans = 1.4142 >> sin(pi/8) ans = 0.3827 >> log(10) ans = 2.3026 >> log10(2) ans = 0.3010 The trigonometric functions all take radian arguments; and pi is a built-in constant. The functions log and log10 are the natural logarithm and logarithms to base 10. 2.3 Variables and the workspace When using any sort of computer system, we need to store things with appropriate names. In the context of Matlab, we use variables to store values. Here are some examples: 18 CHAPTER 2. BASIC USE OF MATLAB >> a=5^(7/2) a = 279.5085 >> b=sin(pi/9)-cos(pi/9) b = -0.5977 Note that although a and b are displayed using the short format, Matlab in fact stores their full values. We can see this with: >> format long;a,format a = 2.795084971874737e+02 We can now use these new variables in further calculations: >> log(a^2)/log(5) ans = 7 >> >> atan(1/b) ans = -1.0321 2.3.1 The workspace If you are using a windowed version of Matlab, you may find a Workspace item in the View menu. This lists all your currently defined variables, their numeric data types, and their sizes in bytes. To open the workspace window, use the View menu, and choose Workspace. The same information can be obtained using the whos function: >> whos Name Size Bytes Class a 1x1 8 double array ans 1x1 8 double array b 1x1 8 double array 2.4. DEALING WITH MATRICES 19 Grand total is 3 elements using 24 bytes Note also that ans is variable: it is automatically created by Matlab to store the result of the last calculation. A listing of the variable names only is obtained using who: >> who Your variables are: a ans b The numeric date type double is Matlab’s standard for numbers; such numbers are stored as doubleprecision 8-byte values. Other data types will be discussed below. 2.4 Dealing with matrices Matlab has an enormous number of commands for generating and manipulating matrices. Since a greyscale image is an matrix, we can use some of these commands to investigate aspects of the image. We can enter a small matrix by listing its elements row by row, using spaces or commas as delimiters for the elements in each row, and using semicolons to separate the rows. Thus the matrix                      can be entered as >> a=[4 -2 -4 7;1 5 -3 2;6 -8 -5 -6;-7 3 0 1] 2.4.1 Matrix elements Matrix elements can be obtained by using the standard row, column indexing scheme. So for our image matrix a above, the command >> a(2,3) ans = -3 returns the element of the matrix in row 2 and column 3. Matlab also allows matrix elements to be obtained using a single number; this number being the position when the matrix is written out as a single column. Thus in a  matrix as a 20 CHAPTER 2. BASIC USE OF MATLAB the order of elements is                       So the element a(2,3) can also be obtained as a(10): >> a(10) ans = -3 In general, for a matrix  with rows and columns, element    corresponds to        . Using the single indexing allows us to extract multiple values from a matrix: >> a([1 6 11 16]) ans = 4 5 -5 1 To obtain a row of values, or a block of values, we use Matlab’s colon operator (:). This generates a vector of values; the command a:b where a and b are integers, lists all integers from a to b. The more general version of this command: i:b lists all values from a by increment i up to b. So for example: >> 2:3:16 generates the list ans = 2 5 8 11 14 Applied to our matrix a, for example: >> a(2,1:3) ans = 6 -8 -5 lists all values in row 2 which are between columns 1 and 3 inclusive. Simil 2.4. DEALING WITH MATRICES 21 >> a(2:4,3) ans = -3 -5 0 lists all the values in column 3 which are between rows 2 to 4 inclusive. And we can choose a block of values such as >> a(2:3,3:4) ans = -3 2 -5 -6 which lists the 2 by 2 block of values which lie between rows 2 to 3 and columns 3 to 4. The colon operator by itself lists all the elements along that particular row or column. So, for example, all of row 3 can be obtained with: >> a(3,:) ans = 6 -8 -5 -6 and all of column 2 with >> a(:,2) ans = -2 5 -8 3 Finally, the colon on its own lists all the matrix elements as a single column: a(:) shows all the 16 elements of a. 2.4.2 Matrix operations All the standard operations are supported. We can add, subtract, multiply and invert matrices, and take matrix powers. For example, with the matrix a from above, and a new matrix b defined by 22 CHAPTER 2. BASIC USE OF MATLAB >> b=[2 4 -7 -4;5 6 3 -2;1 -8 -5 -3;0 -6 7 -1] we can have, for example: >> 2*a-3*b ans = 2 -16 13 26 -13 -8 -15 10 9 8 5 -3 -14 24 -21 1 As an example of matrix powers: >> a^3*b^4 ans = 103788 2039686 1466688 618345 964142 2619886 2780222 345543 -2058056 -2327582 721254 1444095 1561358 3909734 -3643012 -1482253 Inversion is performed using the inv function: >> inv(a) ans = -0.0125 0.0552 -0.0231 -0.1619 -0.0651 0.1456 -0.0352 -0.0466 -0.0406 -0.1060 -0.1039 -0.1274 0.1082 -0.0505 -0.0562 0.0064 A transpose is obtained by using the apostrophe: >> a’ ans = 4 1 6 -7 -2 5 -8 3 -4 -3 -5 0 7 2 -6 1 As well as these standard arithmetic operations, Matlab supports some geometric operations on matrices; flipud and fliplr flip a matrix up/down and left/right respectively, and rot90 rotates a matrix by 90 degrees: 2.4. DEALING WITH MATRICES 23 >> flipud(a) ans = -7 3 0 1 6 -8 -5 -6 1 5 -3 2 4 -2 -4 7 >> fliplr(a) ans = 7 -4 -2 4 2 -3 5 1 -6 -5 -8 6 1 0 3 -7 >> rot90(a) ans = 7 2 -6 1 -4 -3 -5 0 -2 5 -8 3 4 1 6 -7 The reshape function produces a matrix with elements taken column by column from the given matrix. Thus: >> c=[1 2 3 4 5;6 7 8 9 10;11 12 13 14 15;16 17 18 19 20] c = 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 >> reshape(c,2,10) ans = 1 11 2 12 3 13 4 14 5 15 6 16 7 17 8 18 9 19 10 20 >> reshape(c,5,4) 24 CHAPTER 2. BASIC USE OF MATLAB ans = 1 7 13 19 6 12 18 5 11 17 4 10 16 3 9 15 2 8 14 20 Reshape produces an error if the product of the two values is not equal to the number of elements of the matrix. Note that we could have produced the original matrix above with >> c=reshape([1:20],5,4])’ All these commands work equally well on vectors. In fact, Matlab makes no distinction between matrices and vectors; a vector merely being a matrix with number of rows or columns equal to 1. The dot operators A very distinctive class of operators in Matlab are those which use dots; these operate in an element-wise fashion. For example, the command b performs the usual matrix multiplication of a and b. But the corresponding dot operator: *b produces the matrix whose elements are the products of the corresponding elements of a and b. That is, if a.*b then           : >> a.*b ans = 8 -8 28 -28 5 30 -9 -4 6 64 25 18 0 -18 0 -1 We have dot division, and dot powers. The command a.^2 produces a matrix each element of which is a square of the corresponding elements of a: >> a.^2 ans = 16 4 16 49 1 25 2.4. DEALING WITH MATRICES 25 36 64 25 36 49 9 0 1 Similarly we can produce a matrix of reciprocals by writing 1./a: >> 1./a ans = 0.2500 -0.5000 -0.2500 0.1429 1.0000 0.2000 -0.3333 0.5000 0.1667 -0.1250 -0.2000 -0.1667 -0.1429 0.3333 Inf 1.0000 The value Inf is Matlab’s version of infinity; it is returned for the operation  . Operators on matrices Many functions in Matlab, when applied to a matrix, work by applying the function to each element in turn. Such functions are the trigonometric and exponential functions, and logarithms. The use of functions in this way means that in Matlab many iterations and repetitions can be done with vectorization rather than by using loops. We will explore this below. 2.4.3 Constructing matrices We have seen that we can construct matrices by listing all their elements. However, this can be tedious if the matrix is large, or if it can be generated by a function of its indices. Two special matrices are the matrix consisting of all zeros, and the matrix consisting of all ones. These are generated by the zero and ones functions respectively. Each function can be used in several different ways: zeros(n) if n is a number, will produce a zeros matrix of size  zeros(m,n) if m and n are numbers, will produce a zeros matrix of size   zeros(m,n,p,...) where m, n, p and so on are numbers, will produce an     multidimensional array of zeros zeros(a) where a is a matrix, will produce a matrix of zeros of the same size as a. Matrices of random numbers can be produced using the rand and randn functions. They differ in that the numbers produced by rand are taken from a uniform distribution on the interval    , and those produced by randn are take from a normal distribution with mean zero and standard deviation one. For creating matrices the syntax of each is the same as the first three options of zeros above. The rand and randn functions on their own produce single numbers taken from the appropriate distribution. We can construct random integer matrices by multiplying the results of rand or randn by an integer and then using the floor function to take the integer part of the result: >> floor(10*rand(3)) 26 CHAPTER 2. BASIC USE OF MATLAB 8 4 6 8 8 8 5 8 6 >> floor(100*randn(3,5)) ans = -134 -70 -160 -40 71 71 85 -145 68 129 162 125 57 81 66 The floor function will be automatically applied to every element in the matrix. Suppose we wish to create a matrix every element of which is a function of one of its indices. For example, the    matrix for which      . In most programming languages, such a task would be performed using nested loops. We can use nested loops in Matlab, but it is easier here to use dot operators. We can first construct two matrices: one containing all the row indices, and one containing all the column indices: >> rows=(1:10)’*ones(1,10) rows = 1 1 1 1 1 1 1 1 1 1 2 2 2 2 2 2 2 2 2 2 3 3 3 3 3 3 3 3 3 3 4 4 4 4 4 4 4 4 4 4 5 5 5 5 5 5 5 5 5 5 6 6 6 6 6 6 6 6 6 6 7 7 7 7 7 7 7 7 7 7 8 8 8 8 8 8 8 8 8 8 9 9 9 9 9 9 9 9 9 9 10 10 10 10 10 10 10 10 10 10 >> cols=ones(10,1)*(1:10) cols = 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 9 10 1 2 3 4 5 6 7 8 2.4. DEALING WITH MATRICES 27 Now we can construct our matrix using rows and cols: >> A=rows+cols-1 A = 1 2 3 4 5 6 7 8 9 10 2 3 4 5 6 7 8 9 10 11 3 4 5 6 7 8 9 10 11 12 4 5 6 7 8 9 10 11 12 13 5 6 7 8 9 10 11 12 13 14 6 7 8 9 10 11 12 13 14 15 7 8 9 10 11 12 13 14 15 16 8 9 10 11 12 13 14 15 16 17 9 10 11 12 13 14 15 16 17 18 10 11 12 13 14 15 16 17 18 19 The construction of rows and cols can be done automatically with the meshgrid function: [cols,rows]=meshgrid(1:10,1:10) will produce the two index matrices above. The size of our matrix a can be obtained by using the size function: >> size(a) ans = 4 4 which returns the number of rows and columns of a. 2.4.4 Vectorization Vectorization, in Matlab, refers to an operation carried out over an entire matrix or vector. We have seen examples of this already, in our construction of the    matrix above, and in our use of the dot operators. In most programming languages, applying an operation to elements of a list or array will require the use of a loop, or a sequence of nested loops. Vectorization in Matlab allows us to dispense with loops in almost all instances, and is a very efficient replacement for them. For example, suppose we wish to calculate the sine values of all the integer radians one to one million. We can do this with a for loop: >> for i=1:10^6,sin(i);end and we can measure the time of the operation with Matlab’s tic, toc timer: tic starts a stop watch timer, and toc stops it and prints out the elapsed time in seconds. Thus, on my computer: >> tic,for i=1:10^6,sin(i);end,toc elapsed_tim 28 CHAPTER 2. BASIC USE OF MATLAB 27.4969 We can perform the same calculation with: >> i=1:10^6;sin(i); and print out the elapsed time with: >> tic,i=1:10^6;sin(i);toc elapsed_time = 1.3522 Note that the second command applies the sine function to all the elements of the vector 1:10^6, whereas with the for loop, sine is only applied to each element of the loop in turn. As another example, we can easily generate the first 10 square nunmbers with: >> [1:10].^2 ans = 1 4 9 16 25 36 49 64 81 100 What happens here is that [1:10] generates a vector consisting of the numbers 1 to 10; and the dot operator .^2 squares each element in turn. Vectorization can also be used with logical operators; we can obtain all positive elements of the matrix a above with: >> a>0 ans = 1 0 0 1 1 1 0 1 1 0 0 0 0 1 0 1 The result consists of 1’s only in the places where the elements are positive. Matlab is designed to perform vectorized commands very quickly, and whenever possible such a command should be used instead of a for loop. 2.5 Plots Matlab has outstanding graphics capabilities. But we shall just look at some simple plots. The idea is straightforward: we create two vectors x and y of the same size, then the command plot(x,y) will plot y against x. If y has been created from x by using a vectorized function     the plot will show the graph of      . Here’s a simple example 2.5. PLOTS 29 >> x=[0:0.1:2*pi]; >> plot(x,sin(x)) and the result is shown in figure 2.2. The plot function can be used to produce many different plots. 0 1 2 3 4 5 6 7 −1 −0.8 −0.6 −0.4 −0.2 0 0.2 0.4 0.6 0.8 1 Figure 2.2: A simple plot in Matlab We can, for example, plot two functions simultaneously with different colours or plot symbols. For example: >> plot(x,sin(x),’.’,x,cos(x),’o’) produces the graph shown in figure 2.3. 0 1 2 3 4 5 6 7 −1 −0.8 −0.6 −0.4 −0.2 0 0.2 0.4 0.6 0.8 1 Figure 2.3: A different plot in Matlab 30 CHAPTER 2. BASIC USE OF MATLAB 2.6 Help in Matlab Matlab comes with a vast amount of online help and information. So much, in fact, that it’s quite easy to use Matlab without a manual. To obtain information on a particular command, you can use help. For example: >> help for FOR Repeat statements a specific number of times. The general form of a FOR statement is: FOR variable = expr, statement, ..., statement END The columns of the expression are stored one at a time in the variable and then the following statements, up to the END, are executed. The expression is often of the form X:Y, in which case its columns are simply scalars. Some examples (assume N has already been assigned a value). FOR I = 1:N, FOR J = 1:N, A(I,J) = 1/(I+J-1); END END FOR S = 1.0: -0.1: 0.0, END steps S with increments of -0.1 FOR E = EYE(N), ... END sets E to the unit N-vectors. Long loops are more memory efficient when the colon expression appears in the FOR statement since the index vector is never created. The BREAK statement can be used to terminate the loop prematurely. See also IF, WHILE, SWITCH, BREAK, END. If there is too much information, it may scroll past you too fast to see. In such case you can turn on the Matlab pager with the command >> more on For more help on help, try: >> help help Better formatted help can be obtained with the doc function, which opens up a help browser which interprets HTML-formatted help files. The result of the command >> doc help is the window shown in figure 2.4. 2.6. HELP IN MATLAB 31 Figure 2.4: The Matlab help browser You can find more about the doc function with any of >> doc doc >> help doc If you want to find help on a particular topic, but don’t know the function to use, the lookfor function is extremely helpful. The command lookfor topic lists all commands for which the first line of the help text contains the string topic. For example, suppose we want to find out if Matlab supports the exponential function   Here’s how: >> lookfor exponential EXP Exponential. EXPINT Exponential integral function. EXPM Matrix exponential. EXPM1 Matrix exponential via Pade approximation. EXPM2 Matrix exponential via Taylor series. EXPM3 Matrix exponential via eigenvalues and eigenvectors. BLKEXP Defines a function that returns the exponential of the input. and we now know that the function is implemented using exp. We could have used >> lookfor exp and this would have returned many more functions. Note that Matlab convention is to use uppercase names for functions in help texts, even though the function itself is called in lowercase 32 CHAPTER 2. BASIC USE OF MATLAB Exercises 1.

Experiment Chapter 3 Images and Matlab We have seen in the previous chapter that matrices can be handled very efficiently in Matlab. Images may be considered as matrices whose elements are the pixel values of the image. In this chapter we shall investigate how the matrix capabilities of Matlab allow us to investigate images and their properties. 3.1 Greyscale images Suppose you are sitting at your computer and have started Matlab. You will have a Matlab command window open, and in it the Matlab prompt >> ready to receive commands. Type in the command >> w=imread(’wombats.tif’); This takes the grey values of all the pixels in the greyscale image wombats.tif and puts them all into a matrix w. This matrix w is now a Matlab variable, and so we can perform various matrix operations on it. In general the imread function reads the pixel values from an image file, and returns a matrix of all the pixel values. Two things to note about this command: 1. It ends in a semicolon; this has the effect of not displaying the results of the command to the screen. As the result of this particular command is a matrix of size  , or with     elements, we don’t really want all its values displayed. 2. The name wombats.tif is given in single quote marks. Without them, Matlab would assume that wombats.tif was the name of a variable, rather than the name of a file. Now we can display this matrix as a greyscale image: >> figure,imshow(w),pixval on This is really three commands on the one line. Matlab allows many commands to be entered on the same line; using commas to separate the different commands. The three commands we are using here are: 34 CHAPTER 3. IMAGES AND MATLAB figure, which creates a figure on the screen. A figure is a window in which a graphics object can be placed. Objects may include images, or various types of graphs. imshow(g), which displays the matrix g as an image. pixval on, which turns on the pixel values in our figure. This is a display of the grey values of the pixels in the image. They appear at the bottom of the figure in the form  where is the column value of the given pixel; its row value, and its grey value. Since wombats.tif is an 8-bit greyscale image, the pixel values appear as integers in the range –  . This is shown in figure 3.1. Figure 3.1: The wombats image with pixval on If there are no figures open, then an imshow command, or any other command which generates a graphics object, will open a new figure for displaying the object. However, it is good practice to use the figure command whenever you wish to create a new figure. We could display this image directly, without saving its grey values to a matrix, with the command imshow(’wombats.tif’) However, it is better to use a matrix, seeing as these are handled very efficiently in Matl 3.2. RGB IMAGES 35 3.2 RGB Images Matlab handles 24-bit RGB images in much the same way as greyscale. We can save the colour values to a matrix and view the result: >> a=imread(’autumn.tif’); >> figure,imshow(a),pixval on Note now that the pixel values now consist of a list of three values, giving the red, green and blue components of the colour of the given pixel. An important difference between this type of image and a greyscale image can be seen by the command >> size(a) which returns three values: the number of rows, columns, and “pages” of a, which is a threedimensional matrix, also called a multidimensional array. Matlab can handle arrays of any dimension, and a is an example. We can think of a as being a stack of three matrices, each of the same size. To obtain any of the RGB values at a given location, we use similar indexing methods to above. For example >> a(100,200,2) returns the second colour value (green) at the pixel in row 100 and column 200. If we want all the colour values at that point, we can use >> a(100,200,1:3) However, Matlab allows a convenient shortcut for listing all values along a particular dimension; just using a colon on its own: >> a(100,200,:) A useful function for obtaining RGB values is impixel; the command >> impixel(a,200,100) returns the red, green, and blue values of the pixel at column 200, row 100. Notice that the order of indexing is the same as that which is provided by the pixval on command. This is opposite to the row, column order for matrix indexing. This command also applies to greyscale images: >> impixel(g,100,200) will return three values, but since g is a single two-dimensional matrix, all three values will be the same. 3.3 Indexed colour images The command >> figure,imshow(’emu.tif’),pixval on 36 CHAPTER 3. IMAGES AND MATLAB produces a nice colour image of an emu. However, the pixel values, rather than being three integers as they were for the RGB image above, are three fractions between 0 and 1. What is going on here? If we try saving to a matrix first and then displaying the result: >> em=imread(’emu.tif’); >> figure,imshow(em),pixval on we obtain a dark, barely distinguishable image, with single integer grey values, indicating that em is being interpreted as a single greyscale image. In fact the image emu.tif is an example of an indexed image, consisting of two matrices: a colour map, and an index to the colour map. Assigning the image to a single matrix picks up only the index; we need to obtain the colour map as well: >> [em,emap]=imread(’emu.tif’); >> figure,imshow(em,emap),pixval on Matlab stores the RGB values of an indexed image as values of type double, with values between 0 and 1. Information about your image A great deal of information can be obtained with the imfinfo function. For example, suppose we take our indexed image emu.tif from above. >> imfinfo(’emu.tif’) ans = Filename: ’emu.tif’ FileModDate: ’26-Nov-2002 14:23:01’ FileSize: 119804 Format: ’tif’ FormatVersion: [] Width: 331 Height: 384 BitDepth: 8 ColorType: ’indexed’ FormatSignature: [73 73 42 0] ByteOrder: ’little-endian’ NewSubfileType: 0 BitsPerSample: 8 Compression: ’PackBits’ PhotometricInterpretation: ’RGB Palette’ StripOffsets: [16x1 double] SamplesPerPixel: 1 RowsPerStrip: 24 StripByteCounts: [16x1 double] XResolution: 72 YResolution: 72 3.3.

For comparison, let’s look at the output of a true colour file (showing only the first few lines of the output): >> imfinfo(’flowers.tif’) ans = Filename: [1x57 char] FileModDate: ’26-Oct-1996 02:11:09’ FileSize: 543962 Format: ’tif’ FormatVersion: [] Width: 500 Height: 362 BitDepth: 24 ColorType: ’truecolor’ Now we shall test this function on a binary image: >> imfinfo(’text.tif’) ans = Filename: [1x54 char] FileModDate: ’26-Oct-1996 02:12:23’ FileSize: 3474 Format: ’tif’ FormatVersion: [] Width: 256 Height: 256 BitDepth: 1 ColorType: ’grayscale’ 38 CHAPTER 3. IMAGES AND MATLAB What is going on here? We have a binary image, and yet the colour type is given as “grayscale”. The fact is that Matlab does not distinguish between greyscale and binary images: a binary image is just a special case of a greyscale image which has only two intensities. However, we can see that text.tif is a binary image since the number of bits per pixel is only one. 3.4 Data types and conversions Elements in Matlab matrices may have a number of different numeric data types; the most common are listed in table 3.1. There are others; see the help for datatypes. These data types are also Data type Description Range int8 8-bit integer   — 127 uint8 8-bit unsigned integer 0 — 255 int16 16-bit integer    — 32767 uint16 16-bit unsigned integer 0 — 65535 double Double precision real number Machine specific Table 3.1: Data types in Matlab functions, we can convert from one type to another. For example: >> a=23; >> b=uint8(a); >> b b = 23 >> whos a b Name Size Bytes Class a 1x1 8 double array b 1x1 1 uint8 array Even though the variables a and b have the same numeric value, they are of different data types. An important consideration (of which we shall more) is that arithmetic operations are not permitted with the data types int8, int16, uint8 and uint16. A greyscale image may consist of pixels whose values are of data type uint8. These images are thus reasonably efficient in terms of storage space, since each pixel requires only one byte. However, arithmetic operations are not permitted on this data type; a uint8 image must be converted to double before any arithmetic is attempted. We can convert images from one image type to another. Table 3.2 lists all of Matlab’s functions for converting between different image types. Note that the gray2rgb function, does not create a colour image, but an image all of whose pixel colours were the same as before. This is done 3.4. DATA TYPES AND CONVERSIONS 39 Function Use Format ind2gray Indexed to Greyscale y=ind2gray(x,map); gray2ind Greyscale to indexed [y,map]=gray2ind(x); rgb2gray RGB to greyscale y=rgb2gray(x); gray2rgb Greyscale to RGB y=gray2rgb(x); rgb2ind RGB to indexed [y,map]=rgb2ind; ind2rgb Indexed to RGB y=ind2rgb(x,map); Table 3.2: Converting images in Matlab simply replicating the grey values of each pixel: greys in an RGB image are obtained by equality of the red, green and blue values.

Make a list of these sample images, and for each image (a) determine its type (binary, greyscale, true colour or indexed colour), (b) determine its size (in pixels) (c) give a brief description of the picture (what it looks like; what it seems to be a pixture of) 2. Pick a greyscale image, say cameraman.tif or wombats.tif. Using the imwrite function, write it to files of type JPEG, PNG and BMP. What are the sizes of those files? 3. Repeat the above question with (a) a binary image, (b) an indexed colour image, (c) a true colour image. 40 CHAPTER 3. IMAGES AND MATLAB Chapter 4 Image Display 4.1 Introduction We have touched briefly in chapter 2 on image display. In this chapter, we investigate this matter in more detail. We look more deeply at the use of the imshow function, and how spatial resolution and quantization can affect the display and appearance of an image. In particular, we look at image quality, and how that may be affected by various image attributes. Quality is of course a highly subjective matter: no two people will agree precisely as to the quality of different images. However, for human vision in general, images are preferred to be sharp and detailed. This is a consequence of two properties of an image: its spatial resolution, and its quantization. 4.2 The imshow function Greyscale images We have seen that if x is a matrix of type uint8, then the command imshow(x) will display x as an image. This is reasonable, since the data type uint8 restricts values to be integers between 0 and 255. However, not all image matrices come so nicely bundled up into this data type, and lots of Matlab image processing commands produces output matrices which are of type double. We have two choices with a matrix of this type: 1. convert to type uint8 and then display, 2. display the matrix directly. The second option is possible because imshow will display a matrix of type double as a greyscale image as long as the matrix elements are between 0 and 1. Suppose we take an image and convert it to type double: >> c=imread(’caribou.tif’); >> cd=double(c); >> imshow(c),figure,imshow(cd) 41 42 CHAPTER 4. IMAGE DISPLAY (a) The original image (b) After conversion to type double Figure 4.1: An attempt at data type conversion The results are shown in figure 4.1. However, as you can see, figure 4.1(b) doesn’t look much like the original picture at all! This is because for a matrix of type double, the imshow function expects the values to be between 0 and 1, where 0 is displayed as black, and 1 is displayed as white. A value with    is displayed as grey scale   . Conversely, values greater than 1 will be displayed as 1 (white) and values less than 0 will be displayed as zero (black). In the caribou image, every pixel has value greater than or equal to 1 (in fact the minimum value is 21), so that every pixel will be displayed as white. To display the matrix cd, we need to scale it to the range 0—1. This is easily done simply by dividing all values by 255: >> imshow(cd/255) and the result will be the caribou image as shown in figure 4.1(a). We can vary the display by changing the scaling of the matrix. Results of the commands: >> imshow(cd/512) >> imshow(cd/128) are shown in figures 4.2. Dividing by 512 darkens the image, as all matrix values are now between 0 and 0.5, so that the brightest pixel in the image is a mid-grey. Dividing by 128 means that the range is 0—2, and all pixels in the range 1—2 will be displayed as white. Thus the image has an over-exposed, washed-out appearance. The display of the result of a command whose output is a matrix of type double can be greatly affected by a judicious choice of a scaling factor. We can convert the original image to double more properly using the function im2double. This applies correct scaling so that the output values are between 0 and 1. So the commands >> cd=im2double(c); >> imsho 4.2. THE IMSHOW FUNCTION 43 (a) The matrix cd divided by 512 (b) The matrix cd divided by 128 Figure 4.2: Scaling by dividing an image matrix by a scalar will produce a correct image. It is important to make the distinction between the two functions double and im2double: double changes the data type but does not change the numeric values; im2double changes both the numeric data type and the values. The exception of course is if the original image is of type double, in which case im2double does nothing. Although the command double is not of much use for direct image display, it can be very useful for image arithmetic. We have seen examples of this above with scaling. Corresponding to the functions double and im2double are the functions uint8 and im2uint8. If we take our image cd of type double, properly scaled so that all elements are between 0 and 1, we can convert it back to an image of type uint8 in two ways: >> c2=uint8(255*cd); >> c3=im2uint8(cd); Use of im2uint8 is to be preferred; it takes other data types as input, and always returns a correct result. Binary images Recall that a binary image will have only two values: 0 and 1. Matlab does not have a binary data type as such, but it does have a logical flag, where uint8 values as 0 and 1 can be interpreted as logical data. The logical flag will be set by the use of relational operations such as ==, < or > or any other operations which provide a yes/no answer. For example, suppose we take the caribou matrix and create a new matrix with >> cl=c>120; (we will see more of this type of operation in chapter 5.) If we now check all of our variables with whos, the output will include the line: cl 256x256 65536 uint8 array (logical) 44 CHAPTER 4. IMAGE DISPLAY This means that the command >> imshow(cl) will display the matrix as a binary image; the result is shown in figure 4.3. (a) The caribou image turned binary (b) After conversion to type uint8 Figure 4.3: Making the image binary Suppose we remove the logical flag from cl; this can be done by a simple command: >> cl = +cl; Now the output of whos will include the line: cl 256x256 65536 uint8 array If we now try to display this matrix with imshow, we obtain the result shown in figure 4.3(b). A very disappointing image! But this is to be expected; in a matrix of type uint8, white is 255, 0 is black, and 1 is a very dark grey–indistinguishable from black. To get back to a viewable image, we can either turn the logical flag back on, and the view the result: >> imshow(logical(cl)) or simply convert to type double: >> imshow(double(cl)) Both these commands will produce the image seen in figure 4.3. 4.3 Bit planes Greyscale images can be transformed into a sequence of binary images by breaking them up into their bit-planes. If we consider the grey value of each pixel of an 8-bit image as an 8-bit binary word, 4.4. SPATIAL RESOLUTION 45 then the 0th bit plane consists of the last bit of each grey value. Since this bit has the least effect in terms of the magnitude of the value, it is called the least significant bit, and the plane consisting of those bits the least significant bit plane. Similarly the 7th bit plane consists of the first bit in each value. This bit has the greatest effect in terms of the magnitude of the value, so it is called the most significant bit, and the plane consisting of those bits the most significant bit plane. If we take a greyscale image, we start by making it a matrix of type double; this means we can perform arithmetic on the values. >> c=imread(’cameraman.tif’); >> cd=double(c); We now isolate the bit planes by simply dividing the matrix cd by successive powers of 2, throwing away the remainder, and seeing if the final bit is 0 or 1. We can do this with the mod function. >> c0=mod(cd,2); >> c1=mod(floor(cd/2),2); >> c2=mod(floor(cd/4),2); >> c3=mod(floor(cd/8),2); >> c4=mod(floor(cd/16),2); >> c5=mod(floor(cd/32),2); >> c6=mod(floor(cd/64),2); >> c7=mod(floor(cd/128),2); These are all shown in figure 4.4. Note that the least significant bit plane, c0, is to all intents and purposes a random array, and that we see more of the image appearing. The most significant bit plane, c7, is actually a threshold of the image at level 127: >> ct=c>127; >> all(c7(:)==ct(:)) ans = 1 We shall discuss thresholding in chapter 5. We can recover and display the original image with >> cc=2*(2*(2*(2*(2*(2*(2*c7+c6)+c5)+c4)+c3)+c2)+c1)+c0; >> imshow(uint8(cc)) 4.4 Spatial Resolution Spatial resolution is the density of pixels over the image: the greater the spatial resolution, the more pixels are used to display the image. We can experiment with spatial resolution with Matlab’s imresize function. Suppose we have an    8-bit greyscale image saved to the matrix x. Then the command imresize(x,1/2 46 CHAPTER 4.

It does this by taking out every other row and every other column, thus leaving only those matrix elements whose row and column indices are even:                                                                             . . . . . . . . . . . . . . . . . . . . .  imresize(x,1/2)                             . . . . . . . . . . . .

IMAGE DISPLAY Chapter 5 Point Processing 5.1 Introduction Any image processing operation transforms the grey values of the pixels. However, image processing operations may be divided into into three classes based on the information required to perform the transformation. From the most complex to the simplest, they are: 1. Transforms. We require a knowledge of all the grey levels in the entire image to transform the image. In other words, the entire image is processed as a single large block. This may be illustrated by the diagram shown in figure 5.1.  Image Transformed image Processed transformed image Processed original image Transform Inverse transform Image processing operation Figure 5.1: Schema for transform processing 2. Spatial filters. To change the grey level of a given pixel we need only know the value of the grey levels in a small neighbourhood of pixels around the given pixel. 3. Point operations. A pixel’s grey value is changed without any knowledge of its surrounds. Although point operations are the simplest, they contain some of the most powerful and widely used of all image processing operations. They are especially useful in image pre-processing, where an image is required to be modified before the main job is attempted. 5 52 CHAPTER 5. POINT PROCESSING 5.2 Arithmetic operations These operations act by applying a simple function      to each grey value in the image. Thus     is a function which maps the range      onto itself. Simple functions include adding or subtract a constant value to each pixel:   " or multiplying each pixel by a constant:  "  In each case we may have to fiddle the output slightly in order to ensure that the results are integers in the      range. We can do this by first rounding the result (if necessary) to obtain an integer, and then “clipping” the values by setting:    if   , if   . We can obtain an understanding of how these operations affect an image by looking at the graph of old grey values against new values. Figure 5.2 shows the result of adding or subtracting 128 from each pixel in the image. Notice that when we add 128, all grey values of 127 or greater will     Old values New values Adding 128 to each pixel     Old values New values Subtracting 128 from each pixel Figure 5.2: Adding and subtracting a constant be mapped to 255. And when we subtract 128, all grey values of 128 or less will be mapped to 0. By looking at these graphs, we see that in general adding a constant will lighten an image, and subtracting a constant will darken it. We can test this on the “blocks” image blocks.tif, which we have seen in figure 1.4. We start by reading the image in: >> b=imread(’blocks.tif’); >> whos b Name Size Bytes Class b 256x2 5.2. ARITHMETIC OPERATIONS 53 The point of the second command was to find the numeric data type of b; it is uint8. The unit8 data type is used for data storage only; we can’t perform arithmetic operations. If we try, we just get an error message: >> b1=b+128 ??? Error using ==> + Function ’+’ not defined for variables of class ’uint8’. We can get round this in two ways. We can first turn b into a matrix of type double, add the 128, and then turn back to uint8 for display: >> b1=uint8(double(b)+128); A second, and more elegant way, is to use the Matlab function imadd which is designed precisely to do this: >> b1=imadd(b,128); Subtraction is similar; we can transform out matrix in and out of double, or use the imsubtract function: >> b2=imsubtract(b,128); And now we can view them: >> imshow(b1),figure,imshow(b2) and the results are seen in figure 5.3. b1: Adding 128 b2: Subtracting 128 Figure 5.3: Arithmetic operations on an image: adding or subtracting a constant We can also perform lightening or darkening of an image by multiplication; figure 5.4 shows some examples of functions which will have these effects. To implement these functions, we use the immultiply function. Table 5.1 shows the particular commands required to implement the functions of figure 5.4. All these images can be viewed with imshow; they are shown in figure 5.5. Compare the results of darkening b2 and b3. Note that b3, although darker than the original, is 54 CHAPTER 5.

ARITHMETIC OPERATIONS 55 still quite clear, whereas a lot of information has been lost by the subtraction process, as can be seen in image b2. This is because in image b2 all pixels with grey values 128 or less have become zero. A similar loss of information has occurred in the images b1 and b4. Note in particular the edges of the light coloured block in the bottom centre; in both b1 and b4 the right hand edge has disappeared. However, the edge is quite visible in image b5. Complements The complement of a greyscale image is its photographic negative. If an image matrix m is of type double and so its grey values are in the range  to  , we can obtain its negative with the command >> 1-m If the image is binary, we can use >> ~m If the image is of type uint8, the best approach is the imcomplement function. Figure 5.6 shows the complement function     , and the result of the commands >> bc=imcomplement(b); >> imshow(bc)     Old values New values      Figure 5.6: Image complementation Interesting special effects can be obtained by complementing only part of the image; for example by taking the complement of pixels of grey value 128 or less, and leaving other pixels untouched. Or we could take the complement of pixels which are 128 or greater, and leave other pixels untouched. Figure 5.7 shows these functions. The effect of these functions is called so 56 CHAPTER 5. POINT PROCESSING     Old values New values Complementing only dark pixels     Old values New values Complementing only light pixels Figure 5.7: Part complementation 5.3 Histograms Given a greyscale image, its histogram consists of the histogram of its grey levels; that is, a graph indicating the number of times each grey level occurs in the image. We can infer a great deal about the appearance of an image from its histogram, as the following examples indicate: In a dark image, the grey levels (and hence the histogram) would be clustered at the lower end: In a uniformly bright image, the grey levels would be clustered at the upper end: In a well contrasted image, the grey levels would be well spread out over much of the range: We can view the histogram of an image in Matlab by using the imhist function: >> p=imread(’pout.tif’); >> imshow(p),figure,imhist(p),axis tight (the axis tight command ensures the axes of the histogram are automatically scaled to fit all the values in). The result is shown in figure 5.8. Since the grey values are all clustered together in the centre of the histogram, we would expect the image to be poorly contrasted, as indeed it is. Given a poorly contrasted image, we would like to enhance its contrast, by spreading out its histogram. There are two ways of doing this. 5.3.1 Histogram stretching (Contrast stretching) Suppose we have an image with the histogram shown in figure 5.9, associated with a table of the numbers  of grey values: Grey level                      5.3. HISTOGRAMS 57 0 50 100 150 200 250 0 500 1000 1500 2000 2500 3000 3500 4000 Figure 5.8: The image pout.tif and its histogram                                 Figure 5.9: A histogram of a poorly contrasted image, and a stret 58 CHAPTER 5. POINT PROCESSING (with  , as before.) We can stretch the grey levels in the centre of the range out by applying the piecewise linear function shown at the right in figure 5.9. This function has the effect of stretching the grey levels – to grey levels –  according to the equation:          where  is the original grey level and  its result after the transformation. Grey levels outside this range are either left alone (as in this case) or transformed according to the linear functions at the ends of the graph above. This yields:          and the corresponding histogram:                   which indicates an image with greater contrast than the original. Use of imadjust To perform histogram stretching in Matlab the imadjust function may be used. In its simplest incarnation, the command imadjust(im,[a,b],[c,d]) stretches the image according to the function shown in figure 5.10. Since imadjust is designed to    Figure 5.10: The stretching functio 5.3. HISTOGRAMS 59 work equally well on images of type double, uint8 or uint16 the values of , , and  must be between 0 and 1; the function automatically converts the image (if needed) to be of type double. Note that imadjust does not work quite in the same way as shown in figure 5.9. Pixel values less than are all converted to , and pixel values greater than are all converted to  . If either of [a,b] or [c,d] are chosen to be [0,1], the abbreviation [] may be used. Thus, for example, the command >> imadjust(im,[],[]) does nothing, and the command >> imadjust(im,[],[1,0]) inverts the grey values of the image, to produce a result similar to a photographic negative. The imadjust function has one other optional parameter: the gamma value, which describes the shape of the function between the coordinates   and    . If gamma is equal to 1, which is the default, then a linear mapping is used, as shown above in figure 5.10. However, values less than one produce a function which is concave downward, as shown on the left in figure 5.11, and values greater than one produce a figure which is concave upward, as shown on the right in figure 5.11.    gamma      gamma   Figure 5.11: The imadjust function with gamma not equal to 1 The function used is a slight variation on the standard line between two points:           Use of the gamma value alone can be enough to substantially change the appearance of the image. For example: >> t=imread(’tire.tif’); >> th=imadjust(t,[],[],0.5); >> imshow(t),figure,imshow(th) produces the result shown in figure 5.12. We may view the imadjust stretching function with the plot function. For example, >> plot(t,th,’.’),axis tight produces the plot shown in figure 5.13. Since p and ph are matrices which contain the original values and the values after the imadjust function, the plot function simply plots them, using 60 CHAPTER 5.

HISTOGRAMS 61 A piecewise linear stretching function We can easily write our own function to perform piecewise linear stretching as shown in figure 5.14. To do this, we will make use of the find function, to find the pixel values in the image between  and  . Since the line between the coordinates     and     has the equation     Figure 5.14: A piecewise linear stretching function              the heart of our function will be the lines pix=find(im >= a(i) & im < a(i+1)); out(pix)=(im(pix)-a(i))*(b(i+1)-b(i))/(a(i+1)-a(i))+b(i); where im is the input image and out is the output image. A simple procedure which takes as inputs images of type uint8 or double is shown in figure 5.15. As an example of the use of this function: >> th=histpwl(t,[0 .25 .5 .75 1],[0 .75 .25 .5 1]); >> imshow(th) >> figure,plot(t,th,’.’),axis tight produces the figures shown in figure 5.16. 5.3.2 Histogram equalization The trouble with any of the above methods of histogram stretching is that they require user input. Sometimes a better approach is provided by histogram equalization, which is an entirely automatic procedure. Suppose our image has different grey levels       , and that grey level  occurs  times in the image. Suppose also that the total number of pixels in the image is (so that      . To transform the grey levels to obtain a better contrasted image, we change grey level  to          and thi 62 CHAPTER 5.

These results are shown in figure 5.19. Notice the far greater spread of the histogram. This corresponds to the greater increase of contrast in the image. We give one more example, that of a very dark image. We can obtain a dark image by t 5.3.

POINT PROCESSING We now have an index matrix c; in this case consisting of values between 0 and 63, and without the colour map. Since the index matrix contains only low values it will appear very dark when displayed. We can display this matrix and its histogram with the usual commands: >> imshow(c),figure,imhist(c),axis tight and the results are shown in figure 5.20. 0 50 100 150 200 250 0 500 1000 1500 2000 2500 3000 Figure 5.20: The index values from cat.tif and its histogram As you see, the very dark image has a corresponding histogram heavily clustered at the lower end of the scale. But we can apply histogram equalization to this image, and display the results: >> ch=histeq(c); >> imshow(ch),figure,imhist(ch),axis tight and the results are shown in figure 5.21. 0 50 100 150 200 250 0 1000 2000 3000 4000 5000 6000 Figure 5.21: The image from 5.20 equalized and its histogram 5.4. THRESHOLDING 67                  Figure 5.22: The cumulative histogram Why it works Consider the histogram in figure 5.17. To apply histogram stretching, we would need to stretch out the values between grey levels 9 and 13. Thus, we would need to apply a piecewise function similar to that shown in figure 5.9. Let’s consider the cumulative histogram, which is shown in figure 5.22. The dashed line is simply joining the top of the histogram bars. However, it can be interpreted as an appropriate histogram stretching function. To do this, we need to scale the  values so that they are between and  , rather than and  . But this is precisely the method described in section 5.3.2. 5.4 Thresholding 5.4.1 Single thresholding A greyscale image is turned into a binary (black and white) image by first choosing a grey level in the original image, and then turning every pixel black or white according to whether its grey value is greater than or less than : A pixel becomes white if its grey level is  , black if its grey level is  . Thresholding is a vital part of image segmentation, where we wish to isolate objects from the background. It is also an important component of robot vision. Thresholding can be done very simply in Matlab. Suppose we have an 8 bit image, stored as the variable X. Then the command X>T will perform the thresholding. We can view the result with imshow. For example, the commands >> r=imread(’rice.tif’); >> imshow(r),figu 68 CHAPTER 5. POINT PROCESSING Figure 5.23: Thresholded image of rice grains will produce the images shown in figure 5.23. The resulting image can then be further processed to find the number, or average size of the grains. To see how this works, recall that in Matlab, an operation on a single number, when applied to a matrix, is interpreted as being applied simultaneously to all elements of the matrix; this is vectorization, which we have seen in chapter 2. The command X>T will thus return 1 (for true) for all those pixels for which the grey values are greater than T, and 0 (for false) for all those pixels for which the grey values are less than or equal to T. We thus end up with a matrix of 0’s and 1’s, which can be viewed as a binary image. The rice image shown above has light grains on a dark background; an image with dark objects over a light background may be treated the same:: >> b=imread(’bacteria.tif’); >> imshow(b),figure,imshow(b>100) will produce the images shown in figure 5.24. Figure 5.24: Thresholded image of bacteria 5.4. THRESHOLDING 69 As well as the above method, Matlab has the im2bw function, which thresholds an image of any data type, using the general syntax im2bw(image,level) where level is a value between 0 and 1 (inclusive), indicating the fraction of grey values to be turned white. This command will work on greyscale, coloured and indexed images of data type uint8, uint16 or double. For example, the thresholded rice and bacteria images above could be obtained using >> im2bw(r,0.43); >> im2bw(b,0.39); The im2bw function automatically scales the value level to a grey value appropriate to the image type, and then performs a thresholding by our first method. As well as isolating objects from the background, thresholding provides a very simple way of showing hidden aspects of an image. For example, the image paper.tif appears all white, as nearly all the grey values are very high. However, thresholding at a high level produces an image of far greater interest. We can use the commands >> p=imread(’paper1.tif’); >> imshow(p),figure,imshow(p>241) to provide the images shown in figure 5.25. Figure 5.25: The paper image and result after thresholding 5.4.2 Double thresholding Here we choose two values and  and apply a thresholding operation as: A pixel becomes white if its grey level is between and  , black if its grey level is otherwise. We can implement this by a simple variation on the above method: X>T1 & 70 CHAPTER 5. POINT PROCESSING Since the ampersand acts as a logical “and”, the result will only produce a one where both inequalities are satisfied. Consider the following sequence of commands, which start by producing an 8-bit grey version of the indexed image spine.tif: >> [x,map]=imread(’spine.tif’); >> s=uint8(256*ind2gray(x,map)); >> imshow(s),figure,imshow(s>115 & s<125) The output is shown in figure 5.26. Note how double thresholding brings out subtle features of the Figure 5.26: The image spine.tif an the result after double thresholding spine which single thresholding would be unable to do. We can obtain similar results using im2bw: imshow(im2bw(x,map,0.45)&~{}im2bw(x,map,0.5))} but this is somewhat slower because of all the extra computation involved when dealing with an indexed image. 5.5 Applications of thresholding We have seen that thresholding can be useful in the following situations: 1. When we want to remove unnecessary detail from an image, to concentrate on essentials. Examples of this were given in the rice and bacteria images: by removing all grey level information, the rice and bacteria were reduced to binary blobs. But this information may be all we need to investigate sizes, shapes, or numbers of blobs. 2. To bring out hidden detail. This was illustrated with paper and spine images. In both, the detail was obscured because of the similarity of the grey levels involved. But thresholding can be vital for other purposes. We list a few more: 3. When we want to remove a varying background from text or a drawing. We can simulate a varying background by taking the image text.tif and placing it on a random background. This can be easily implemented with some simple Matlab commands: 5.5. APPLICATIONS OF THRESHOLDING 71 >> r=rand(256)*128+127; >> t=imread(’text.tif’); >> tr=uint8(r.*double(not(t)); >> imshow(tr) The first command simply uses the rand function (which produces matrices of uniformly generated random numbers between  and  ), and scales the result so the random numbers are between 127 and 255. We then read in the text image, which shows white text on a dark background. The third command does several things at once: not(t) reverses the text image so as to have black text on a white background; double changes the numeric type so that the matrix can be used with arithmetic operations; finally the result is multiplied into the random matrix, and the whole thing converted to uint8 for display. The result is shown on the left in figure 5.27. If we threshold this image and display the result with >> imshow(tr>100) the result is shown on the right in figure 5.27, and the background has been completely removed.

POINT PROCESSING Chapter 6 Spatial Filtering 6.1 Introduction We have seen in chapter 5 that an image can be modified by applying a particular function to each pixel value. Spatial filtering may be considered as an extension of this, where we apply a function to a neighbourhood of each pixel. The idea is to move a “mask”: a rectangle (usually with sides of odd length) or other shape over the given image. As we do this, we create a new image whose pixels have grey values calculated from the grey values under the mask, as shown in figure 6.1. The combination of mask and function Pixel at position     Mask Original image Pixel at position     Image after filtering Figure 6.1: Using a spatial mask on an image is called a filter. If the function by which the new grey value is calculated is a linear function of all the grey values in the mask, then the filter is called a linear filter. We can implement a linear filter by multiplying all elements in the mask by corresponding elements in the neighbourhood, and adding up all these products. Suppose we have a   mask as illustrated in figure 6.1. Suppose that the mask values are given by: 75 76 CHAPTER 6. SPATIAL FILTERING                      and that corresponding pixel values are     ! "#$% &'! (&  )* +#! %  &,!  &#  &-  .&' ! /&,$% .&'&'! .&'(&  We now multiply and add: 0 132  0 42   5 ,   65  ,   A diagram illustrating the process for performing spatial filtering is given in figure 6.2. We see that spatial filtering requires three steps: 1. position the mask over the current pixel, 2. form all products of filter elements with the corresponding elements of the neighbourhood, 3. add up all the products. This must be repeated for every pixel in the image. An example: One important linear filter is to use a   mask and take the average of all nine values within the mask. This value becomes the grey value of the corresponding p 6.1.

SPATIAL FILTERING image. We may describe this operation as follows:           where is grey value of the current pixel in the original image, and the average is the grey value of the corresponding pixel in the new image. To apply this to an image, consider the    “image” obtained by: >> x=uint8(10*magic(5)) x = 170 240 10 80 150 230 50 70 140 160 40 60 130 200 220 100 120 190 210 30 110 180 250 20 90 We may regard this array as being made of nine overlapping   neighbourhoods. The output of our working will thus consist only of nine values. We shall see later how to obtain 25 values in the output. Consider the top left   neighbourhood of our image x: 170 240 10 80 150 230 50 70 140 160 40 60 130 200 220 100 120 190 210 30 110 180 250 20 90 Now we take the average of all these values: >> mean2(x(1:3,1:3)) ans = 111.1111 which we can round to 111. Now we can move to the second ne 6.2. NOTATION 79 170 240 10 80 150 230 50 70 140 160 40 60 130 200 220 100 120 190 210 30 110 180 250 20 90 and take its average: >> mean2(x(1:3,2:4)) ans = 108.8889 and we can round this either down to 108, or to the nearest integer 109. If we continue in this manner, we will build up the following output: 111.1111 108.8889 128.8889 110.0000 130.0000 150.0000 131.1111 151.1111 148.8889 This array is the result of filtering x with the    averaging filter. 6.2 Notation It is convenient to describe a linear filter simply in terms of the coefficients of all the grey values of pixels within the mask. This can be written as a matrix. The averaging filter above, for example, could have its output written as             and so we can describe this filter by the matrix                 An example: The filter       80 CHAPTER 6. SPATIAL FILTERING would operate on grey values as            Edges of the image There is an obvious problem in applying a filter—what happens at the edge of the image, where the mask partly falls outside the image? In such a case, as illustrated in figure 6.3 there will be a lack of grey values to use in the filter function. Figure 6.3: A mask at the edge of an image There are a number of different approaches to dealing with this problem: Ignore the edges. That is, we only apply the mask to those pixels in the image for with the mask will lie fully within the image. This means all pixels except for the edges, and results in an output image which is smaller than the original. If the mask is very large, we may lose a significant amount of information by this method. We applied this method in our example above. “Pad” with zeros. We assume that all necessary values outside the image are zero. This gives us all values to work with, and will return an output image of the same size as the original, but may have the effect of introducing unwanted artifacts (for example, edges) around the image. 6.3 Filtering in Matlab The filter2 function does the job of linear filtering for us; its use is filter2(filter,image,shape) and the result is a matrix of data type double. The parameter shape is optional, it describes the method for dealing with the edges: filter2(filter,image,’same’) is the default; it produces a matrix of equal size to the original image matrix. It uses zero padding: >> a=o 6.3.

We can see that the result will always be smaller than the original: >> filter2(a,x,’valid’) ans = 111.1111 108.8889 128.8889 110.0000 130.0000 150.0000 131.1111 151.1111 148.8889 We can obtain the result of ’same’ above by padding with zeros and using ’valid’: >> x2=zeros(7,7); >> x2(2:6,2:6)=x x2 = 0 0 0 0 0 0 0 0 170 240 10 80 150 0 0 230 50 70 140 160 0 0 40 60 130 200 220 0 0 100 120 190 210 30 0 0 110 180 250 20 90 0 0 0 0 0 0 0 0 >> filter2(a,x2,’valid’) filter2(filter,image,’full’) returns a result larger than the original; it does this by padding with zero, and applying the filter at all places on and around the image where the mask intersects the image matri 82 CHAPTER 6.

There is no single “best” approach; the method must be dictated by the problem at hand; by the filter being used, and by the result required. We can create our filters by hand, or by using the fspecial function; this has many options which makes for easy creation of many different filters. We shall use the average option, which produces averaging filters of given size; thus fspecial(’average’,[5,7]) will return an averaging filter of size ; more simply fspecial(’average’,11) will return an averaging filter of size      . If we leave out the final number or vector, the  averaging filter is returned. For example, suppose we apply the    averaging filter to an image as follows: >> c=imread(’cameraman.tif’); >> f1=fspecial(’average’); >> cf1=filter2(f1,c); We now have a matrix of data type double. To display this, we can do any of the following: transform it to a matrix of type uint8, for use with imshow, divide its values by 255 to obtain a matrix with values in the   –   range, for use with imshow, use mat2gray to scale the result for display. We shall discuss the use of this function later. Using the second method: >> figure,imshow(c),figure,imshow(cf1/255) will produce the images shown in figures 6.4(a) and 6.4(b). The averaging filter blurs the image; the edges in particular are less distinct than in the original. The image can be further blurred by using an averaging filter of larger size. This is sho 6.3. FILTERING IN MATLAB 83 (a) Original image (b) Average filtering (c) Using a  filter (d) Using a   filter Figure 6.4: Average filte 84 CHAPTER 6. SPATIAL FILTERING figure 6.4(c), where a  averaging filter has been used, and in figure 6.4(d), where a    averaging filter has been used. Notice how the zero padding used at the edges has resulted in a dark border appearing around the image. This is especially noticeable when a large filter is being used. If this is an unwanted artifact of the filtering; if for example it changes the average brightness of the image, then it may be more appropriate to use the ’valid’ shape option. The resulting image after these filters may appear to be much “worse” than the original. However, applying a blurring filter to reduce detail in an image may the perfect operation for autonomous machine recognition, or if we are only concentrating on the “gross” aspects of the image: numbers of objects; amount of dark and light areas. In such cases, too much detail may obscure the outcome. 6.4 Frequencies; low and high pass filters It will be convenient to have some standard terminology by which we can discuss the effects a filter will have on an image, and to be able to choose the most appropriate filter for a given image processing task. One important aspect of an image which enables us to do this is the notion of frequencies. Fundamentally, the frequencies of an image are the amount by which grey values change with distance. High frequency components are characterized by large changes in grey values over small distances; example of high frequency components are edges and noise. Low frequency components, on the other hand, are parts of the image characterized by little change in the grey values. These may include backgrounds, skin textures. We then say that a filter is a high pass filter if it “passes over” the high frequency components, and reduces or eliminates low frequency components, low pass filter if it “passes over” the low frequency components, and reduces or eliminates high frequency components, For example, the    averaging filter is low pass filter, as it tends to blur edges. The filter            is a high pass filter. We note that the sum of the coefficients (that is, the sum of all e elements in the matrix), in the high pass filter is zero. This means that in a low frequency part of an image, where the grey values are similar, the result of using this filter is that the corresponding grey values in the new image will be close to zero. To see this, consider a  block of similar values pixels, and apply the above high pass filter to the central four:                                    The resulting values are close to zero, which is the expected result of applying a high pass filter to a low frequency component. We shall see how to deal with negative values below. High pass filters are of particular value in edge detection and edge enhancement (of which we shall see more in chapter 8). But we can provide a sneak preview, using the 6.4.

(a) Laplacian filter (b) Laplacian of Gaussian (“log”) filtering Figure 6.5: High pass filtering In each case, the sum of all the filter elements is zero. 86 CHAPTER 6. SPATIAL FILTERING Values outside the range 0–255 We have seen that for image display, we would like the grey values of the pixels to lie between 0 and 255. However, the result of applying a linear filter may be values which lie outside this range. We may consider ways of dealing with values outside of this “displayable” range. Make negative values positive. This will certainly deal with negative values, but not with values greater than 255. Hence, this can only be used in specific circumstances; for example, when there are only a few negative values, and when these values are themselves close to zero. Clip values. We apply the following thresholding type operation to the grey values  produced by the filter to obtain a displayable value :    if    if        if     This will produce an image with all pixel values in the required range, but is not suitable if there are many grey values outside the 0–255 range; in particular, if the grey values are equally spread over a larger range. In such a case this operation will tend to destroy the results of the filter. Scaling transformation. Suppose the lowest grey value produced by the filter if  and the highest value is . We can transform all values in the range  – to the range 0–255 by the linear transformation illustrated below:   255 Since the gradient of the line is       we can write the equation of the line as          and applying this transformation to all grey levels  produced by the filter will result (after any necessary rounding) in an image which can be displayed. As an example, let’s apply the high pass filter given in section 6.4 to the cameraman image: >> f2=[1 -2 1;-2 4 -2;1 -2 1]; >> cf2=filter2(f2,c); Now the maximum and minimum values of the matrix cf2 are   and    respectively. The mat2gray function automatically scales the matrix elements to displayable values; for any matrix , it applies a linear transformation to to its elements, with the lowest value mapping to 0.0, and the highest value mapping to 1.0. This means the output of mat2gray is always of type double. The function also requires that t 6.5. GAUSSIAN FILTERS 87 >> figure,imshow(mat2gray(cf2)); To do this by hand, so to speak, applying the linear transformation above, we can use: >> maxcf2=max(cf2(:)); >> mincf2=min(cf2(:)); >> cf2g=(cf2-mincf2)/(maxcf2-mncf2); The result will be a matrix of type double, with entries in the range –  . This can be be viewed with imshow. We can make it a uint8 image by multiplying by 255 first. The result can be seen in figure 6.6. We can generally obtain a better result by dividing the result of the filtering by a constant before displaying it: >> figure,imshow(cf2/60) and this is also shown in figure 6.6. Using mat2gray Dividing by a constant Figure 6.6: Using a high pass filter and displaying the result High pass filters are often used for edge detection. These can be seen quite clearly in the right hand image of figure 6.6. 6.5 Gaussian filters We have seen some examples of linear filters so far: the averaging filter, and a high pass filter. The fspecial function can produce many different filters for use with the filter2 function; we shall look at a particularly important filter here. Gaussian filters are a class of low-pass filters, all based on the Gaussian probability distribution function      88 CHAPTER 6. SPATIAL FILTERING where is the standard deviation: a large value of produces to a flatter curve, and a small value leads to a “pointier” curve. Figure 6.7 shows examples of such one dimensional gaussians. Large value of Small value of Figure 6.7: One dimensional gaussians A two dimensional Gaussian function is given by        The command fspecial(’gaussian’) produces a discrete version of this function. We can draw pictures of this with the surf function, and to ensure a nice smooth result, we shall create a large filter (size    ) with different standard deviations. >> a=50;s=3; >> g=fspecial(’gaussian’,[a a],s); >> surf(1:a,1:a,g) >> s=9; >> g2=fspecial(’gaussian’,[a a],s); >> figure,surf(1:a,1:a,g2) The surfaces are shown in figure 6.8. Gaussian filters have a blurring effect which looks very similar to that produced by neighbourhood averaging. Let’s experiment with the cameraman image, and some different gaussian filters. >> g1=fspecial(’gaussian’,[5,5]); >> g1=fspecial(’gaussian’,[5,5],2); >> g1=fspecial(’gaussian’,[11,11],1); >> g1=fspecial(’gaussian’,[11,11],5); The final parameter is the standard deviation; which if not given defaults to  . The second parameter (which is also optional), gives the size of the filter; the default is   . If the filter is to be square, as in all the above examples, we can just give a single number in each case. Now we can apply the filter to the cameraman image matrix c and vier the result. >> imshow(filter2(g1,c)/256) >> figure,imshow(filter2(g2,c)/256) >> figure,imshow(filter2(g3,c)/256) >> figure,imshow(filter2( 6.6.

We see that to obtain a spread out blurring effect, we need a large standard deviation. In fact, if we let the standard deviation grow large without bound, we obtain the averaging filters as limiting values. For example: >> fspecial(’gaussian’,3,100) ans = 0.1111 0.1111 0.1111 0.1111 0.1111 0.1111 0.1111 0.1111 0.1111 and we have the  averaging filter. Although the results of Gaussian blurring and averaging look similar, the Gaussian filter has some elegant mathematical properties which make it particularly suitable for blurring. Other filters will be discussed in future chapters; also check the documentation for fspecial for other filters. 6.6 Non-linear filters Linear filters, as we have seen in the previous sections, are easy to describe, and can be applied very quickly and efficiently by Matlab. However, non-linear filters can also be used, if less efficiently. The function to use is nlfilter, which applies a filter to an image according to a pre-defined function. If the function is not already defined, we have to create an m-file which defines it. Here are some examples; first to define a filter which takes the maximum value in a    neighbourhood: cmax=nlfilter(c,[3,3],’max(x(: 90 CHAPTER 6. SPATIAL FILTERING   ,     ,      ,       ,  Figure 6.9: Effects of different gaussian filters on a 6.6. NON-LINEAR FILTERS 91 The nlfilter function requires three arguments: the image matrix, the size of the filter, and the function to be applied. The function must be a matrix function which returns a scalar value. The result of this operation is shown in figure 6.10(a). A corresponding filter which takes the minimum value can be just as easily applied: cmin=nlfilter(c,[3,3],’min(x(:))’); and the result is shown in figure 6.10(b). (a) Using a maximum filter (b) Using a minimum filter Figure 6.10: Using non-linear filters Both these filters can in fact be more efficiently implemented by using the Matlab function ordfilt2—see its help page! Note that in each case the image has lost some sharpness, and has been brightened by the maximum filter, and darkened by the minimum filter. The nlfilter function is very slow; in general there is little call for non-linear filters except for a few which are defined by their own commands. We shall investigate these in later chapters.

SPATIAL FILTERING Chapter 7 Noise 7.1 Introduction We may define noise to be any degradation in the image signal, caused by external disturbance. If an image is being sent electronically from one place to another, via satellite or wireless transmission, or through networked cable, we may expect errors to occur in the image signal. These errors will appear on the image output in different ways depending on the type of disturbance in the signal. Usually we know what type of errors to expect, and hence the type of noise on the image; hence we can choose the most appropriate method for reducing the effects. Cleaning an image corrupted by noise is thus an important area of image restoration. In this chapter we will investigate some of the standard noise forms, and the different methods of eliminating or reducing their effects on the image. 7.2 Types of noise We will look at four different noise types, and how they appear on an image. Salt and pepper noise Also called impulse noise, shot noise, or binary noise. This degradation can be caused by sharp, sudden disturbances in the image signal; its appearance is randomly scattered white or black (or both) pixels over the image. To demonstrate its appearance, we will first generate a grey-scale image, starting with a colour image: >> tw=imread(’twins.tif’); >> t=rgb2gray(tw); To add noise, we use the Matlab function imnoise, which takes a number of different parameters. To add salt and pepper noise: >> t_sp=imnoise(t,’salt & pepper’); The amount of noise added defaults to  ; to add more or less noise we include an optional parameter, being a value between 0 and 1 indicating the fraction of pixels to be corrupted. Thus, for example 96 CHAPTER 7. NOISE >> imnoise(t,’salt & pepper’,0.2); would produce an image with  of its pixels corrupted by salt and pepper noise. The twins image is shown in figure 7.1(a) and the image with noise is shown in figure 7.1(b). (a) Original image (b) With added salt & pepper noise Figure 7.1: Noise on an image Gaussian noise Gaussian noise is an idealized form of white noise, which is caused by random fluctuations in the signal. We can observe white noise by watching a television which is slightly mistuned to a particular channel. Gaussian noise is white noise which is normally distributed. If the image is represented as , and the Gaussian noise by , then we can model a noisy image by simply adding the two:  Here we may assume that is a matrix whose elements are the pixel values of our image, and  is a matrix whose elements are normally distributed. It can be shown that this is an appropriate model for noise. The effect can again be demonstrated by the imnoise function: >> t_ga=inoise(t,’gaussian’); As with salt and pepper noise, the “gaussian” parameter also can take optional values, giving the mean and variance of the noise. The default values are and   , and the result is shown in figure 7.2(a). Speckle noise Whereas Gaussian noise can be modelled by random values added to an image; speckle noise (or more simply just speckle) can be modelled by random values multiplied by pixel values, hence it is also called multiplicative noise. Speckle noise is a major problem in some radar applications. As above, imnoise can do 7.2. TYPES OF NOISE 97 >> t_spk=imnoise(t,’speckle’); and the result is shown in figure 7.2(b). In Matlab, speckle noise is implemented as    where is the image matrix, and  consists of normally distributed values with mean 0. An optional parameter gives the variance of ; its default value is  . (a) Gaussian noise (b) Speckle noise Figure 7.2: The twins image corrupted by Gaussian and speckle noise Although Gaussian noise and speckle noise appear superficially similar, they are formed by two totally different methods, and, as we shall see, require different approaches for their removal. Periodic noise If the image signal is subject to a periodic, rather than a random disturbance, we might obtain an image corrupted by periodic noise. The effect is of bars over the image. The function imnoise does not have a periodic option, but it is quite easy to create our own, by adding a periodic matrix (using a trigonometric function), to our image: >> s=size(t); >> [x,y]=meshgrid(1:s(1),1:s(2)); >> p=sin(x/3+y/5)+1; >> t_pn=(im2double(t)+p/2)/2; and the resulting image is shown in figure 7.3. Salt and pepper noise, Gaussian noise and speckle noise can all be cleaned by using spatial filtering techniques. Periodic noise, however, requires image transforms for best results, and so we will leave the discussion on cleaning up periodic noise until a later chap 98 CHAPTER 7. NOISE Figure 7.3: The twins image corrupted by periodic noise 7.3 Cleaning salt and pepper noise Low pass filtering Given that pixels corrupted by salt and pepper noise are high frequency components of an image, we should expect a low-pass filter should reduce them. So we might try filtering with an average filter: >> a3=fspecial(’average’); >> t_sp_a3=filter2(a3,t_sp); and the result is shown in figure 7.4(a). Notice, however, that the noise is not so much removed as “smeared” over the image; the result is not noticeably “better” than the noisy image. The effect is even more pronounced if we use a larger averaging filter: >> a7=fspecial(’average’,[7,7]); >> t_sp_a7=filter2(a7,t_sp); and the result is shown in figure 7.4(b). Median filtering Median filtering seems almost tailor-made for removal of salt and pepper noise. Recall that the median of a set is the middle value when they are sorted. If there are an even number of values, the median is the mean of the middle two. A median filter is an example of a non-linear spatial filter; using a   mask, the output value is the median of the values in the mask. For example:                    60          We see that very large or very small values—noisy values—will end up at the top or bottom of the sorted list. Thus the median will in general replace a noisy value with one closer to its surro 7.3. CLEANING SALT AND PEPPER NOISE 99 (a)    averaging (b)    averaging Figure 7.4: Attempting to clean salt & pepper noise with average filtering In Matlab, median filtering is implemented by the medfilt2 function: >> t_sp_m3=medfilt2(t_sp); and the result is shown in figure 7.5. The result is a vast improvement on using averaging filters. As Figure 7.5: Cleaning salt and pepper noise with a median filter with most functions, medfilt2 takes an optional parameter; in this case a 2 element vector giving the size of the mask to be used. If we corrupt more pixels with noise: >> t_sp2=imnoise(t,’salt & pepper’,0.2); then medfilt2 still does a remarkably good job, as shown in figure 7.6. To remove noise completely, 100 CHAPTER 7. NOISE (a) 20% salt & pepper noise (b) After median fitering Figure 7.6: Using a  median filter on more noise we can either try a second application of the    median filter, the result of which is shown in figure 7.7(a) or try a    median filter on the original noisy image: >> t_sp2_m5=medfilt2(t_sp2,[5,5]); the result of which is shown in figure 7.7(b). (a) Using medfilt2 twice (b) using a   median filter Figure 7.7: Cleaning 20% salt & pepper noise with median filtering Rank-order filtering Median filtering is a special case of a more general process called rank-order filtering. Rather than take the median of a set, we order the set and take the -th value, for some predetermined value o 7.3. CLEANING SALT AND PEPPER NOISE 101 Thus median filtering using a    mask is equivalent to rank-order filtering with . Similarly, median filtering using a    mask is equivalent to rank-order filtering with  . Matlab implements rank-order filtering with the ordfilt2 function; in fact the procedure for medfilt2 is really just a wrapper for a procedure which calls ordfilt2. There is only one reason for using rank-order filtering instead of median filtering, and that is that it allows us to choose the median of non-rectangular masks. For example, if we decided to use as a mask a    cross shape: then the median would be the third of these values when sorted. The command to do this is >> ordfilt2(t_sp,3,[0 1 0;1 1 1;0 1 0]); In general, the second argument of ordfilt2 gives the value of the ordered set to take, and the third element gives the domain; the non-zero values of which specify the mask. If we wish to use a cross with size and width 5 (so containing nine elements), we can use: >> ordfilt2(t_sp,5,[0 0 1 0 0;0 0 1 0 0;1 1 1 1 1;0 0 1 0 0;0 0 1 0 0]) An outlier method Applying the median filter can in general be a slow operation: each pixel requires the sorting of at least nine values1 . To overcome this difficulty, Pratt [16] has proposed the use of cleaning salt and pepper noise by treating noisy pixels as outliers; that is, pixels whose grey values are significantly different from those of their neighbours. This leads to the following approach for noise cleaning: 1. Choose a threshold value . 2. For a given pixel, compare its value with the mean  of the values of its eight neighbours. 3. If    , then classify the pixel as noisy, otherwise not. 4. If the pixel is noisy, replace its value with ; otherwise leave its value unchanged. There is no Matlab function for doing this, but it is very easy to write one. First, we can calculate the average of a pixel’s eight neighbours by convolving with the linear filter                                        We can then produce a matrix consisting of 1’s at only those places where the difference of the original and the filter are greater than ; that is, where pixels are noisy. Then   will consist of ones at only those places where pixels are not noisy. Multiplying by the filter replaces noisy values with averages; multiplying   with original values gives the rest of the output. 1 In fact, this is not the case with Matlab, which uses a highly optimized method. Nonetheless, we introduce a different method to show that there are other ways of clean 102 CHAPTER 7. NOISE A Matlab function for implementing this is shown in figure 7.8. An immediate problem with the outlier method is that is it not completely automatic—the threshold must be chosen. An appropriate way to use the outlier method is to apply it with several different thresholds, and choose the value which provides the best results. Suppose we attempt to use the outlier method to clean function res=outlier(im,d) % OUTLIER(IMAGE,D) removes salt and pepper noise using an outlier method. % This is done by using the following algorithm: % % For each pixel in the image, if the difference between its grey value % and the average of its eight neighbours is greater than D, it is % classified as noisy, and its grey value is changed to that of the % average of its neighbours. % % IMAGE can be of type UINT8 or DOUBLE; the output is of type % UINT8. The threshold value D must be chosen to be between 0 and 1. f=[0.125 0.125 0.125; 0.125 0 0.125; 0.125 0.125 0.125]; imd=im2double(im); imf=filter2(f,imd); r=abs(imd-imf)-d>0; res=im2uint8(r.*imf+(1-r).*imd); Figure 7.8: A Matlab function for cleaning salt and pepper noise using an outlier method the noise from figure 7.1(b); that is, the twins image with 10% salt and pepper noise. Choosing  gives the image in figure 7.9(a). This is not as good a result as using a median filter: the affect of the noise has been lessened, but there are still noise “artifacts” over the image. In this case we have chosen a threshold which is too small. If we choose  , we obtain the image in figure 7.9(b), which still has smoe noise artifacts, although in different places. We can see that a lower values of tends to remove noise from dark areas, and a higher value of tends to remove noise from light areas. A mid-way valaue, round about   does in fact produce an acceptable result, although not quite as good as median filtering. Clearly using an appropriate value of is essential for cleaning salt and pepper noise by this method. If is too small, then too many “non-noisy” pixels will be classified as noisy, and their values changed to the average of their neighbours. This will result in a blurring effect, similar to that obtained by using an averaging filter. If is chosen to be too large, then not enough noisy pixels will be classified as noisy, and there will be little change in the output. The outlier method is not particularly suitable for cleaning large amounts of noise; for such situations the median filter is to be preferred. The outlier method may thus be considered as a “quick and dirty” method for cleaning salt and pepper noise when the median filter proves too slow. 7.4 Cleaning Gaussian noise Image averaging It may sometimes happen that instead of just one image corrupted with Gaussian noise, we have many different copies of it. An example is satellite imaging; if a satellite passes over the same spot many times, we will obtain many different images of the same place. Anoth 7.4. CLEANING GAUSSIAN NOISE 103 (a)  (b)  Figure 7.9: Applying the outlier method to 10% salt and pepper noise microscopy: we might take many different images of the same object. In such a case a very simple approach to cleaning Gaussian noise is to simply take the average—the mean—of all the images. T To see why this works, suppose we have 100 copies of our image, each with noise; then the  -th noisy image will be:   where  is the matrix of original values, and  is a matrix of normally distributed random values with mean 0. We can find the mean  of these images by the usual add and divide method:    0   2      0   2    0   2     0   2  Since  is normally distributed with mean 0, it can be readily shown that the mean of all the  ’s will be close to zero—the greater the number of  ’s; the closer to zero. Thus   and the approximation is closer for larger number of images   . We can demonstrate this with the twins image. We first need to create different versions with Gaussian noise, and then take the average of them. We shall create 10 versions. One way is to create an empty three-dimensional array of depth 10, and fill each “level” with a noisy image: >> s=size(t); >> t_ga10=zeros(s(1),s(2),10); >> for i=1:10 t_ga10(:,:,i)=imno 104 CHAPTER 7. NOISE Note here that the “gaussian” option of imnoise calls the random number generator randn, which creates normally distributed random numbers. Each time randn is called, it creates a different sequence of numbers. So we may be sure that all levels in our three-dimensional array do indeed contain different images. Now we can take the average: >> t_ga10_av=mean(t_ga10,3); The optional parameter 3 here indicates that we are taking the mean along the third dimension of our array. The result is shown in figure 7.10(a). This is not quite clear, but is a vast improvement on the noisy image of figure 7.2(a). An even better result is obtained by taking the average of 100 images; this can be done by replacing 10 with 100 in the commands above, and the result is shown in figure 7.10(b). Note that this method only works if the Gaussian noise has mean 0. (a) 10 images (b) 100 images Figure 7.10: Image averaging to remove Gaussian noise Average filtering If the Gaussian noise has mean 0, then we would expect that an average filter would average the noise to 0. The larger the size of the filter mask, the closer to zero. Unfortunately, averaging tends to blur an image, as we have seen in chapter 6. However, if we are prepared to trade off blurring for noise reduction, then we can reduce noise significantly by this method. Suppose we take the    and    averaging filters, and apply them to the noisy image t_ga. >> a3=fspecial(’average’); >> a5=fspecial(’average’,[5,5]); >> tg3=filter2(a3,t_ga); >> tg5=filter2(a5,t_ga); The results are shown in figure 7.11. The results are not really particularly pleasing; although there has been some noise reduction, the “smeary” nature of the resulting images is unattractive. 7.4. CLEANING GAUSSIAN NOISE 105 (a)   averaging (b)  averaging Figure 7.11: Using averaging filtering to remove Gaussian noise Wiener filtering Before we describe this method, we shall discuss a more general question: given a degraded image  of some original image  and a restored version  , what measure can we use to say whether our restoration has done a good job? Clearly we would like  to be as close as possible to the “correct” image . One way of measuring the closeness of  to  is by adding the squares of all differences: 0     where the sum is taken over all pixels of  and  (which we assume to be of the same size). This sum can be taken as a measure of the closeness of  to . If we can minimize this value, we may be sure that our procedure has done as good a job as possible. Filters which operate on this principle of least squares are called Wiener filters. They come in many guises; we shall look at the particular filter which is designed to reduce Gaussian noise. This filter is a (non-linear) spatial filter; we move a mask across the noisy image, pixel by pixel, and as we move, we create an output image the grey values of whose pixels are based on the values under the mask. Since we are dealing with additive noise, our noisy image  can be written as    where  is the original correct image, and  is the noise; which we assume to be normally distributed with mean 0. However, within our mask, the mean may not be zero; suppose the mean is  , and the variance in the mask is  . Suppose also that the variance of the noise over the entire image is known to be  . Then the output value can be calculated as         where is the current value of the pixel in the noisy image. See Lim [13] for details. In practice, we calculate  by simply taking the mean of all grey values under the mask, and  by 106 CHAPTER 7. NOISE the variance of all grey values under the mask. We may not necessarily know the value  , so the Matlab function wiener2 which implements Wiener filtering uses a slight variant of the above equation:             where is the computed noise variance, and is calculated by taking the mean of all values of  over the entire image. This can be very efficiently calculated in Matlab. Suppose we take the noisy image shown in figure 7.2(a), and attempt to clean this image with Wiener filtering. We will use the wiener2 function, which can take an optional parameter indicating the size of the mask to be used. The default size is   . We shall create four images: >> t1=wiener2(t_ga); >> t2=wiener2(t_ga,[5,5]); >> t3=wiener2(t_ga,[7,7]); >> t4=wiener2(t_ga,[9,9]); and these are shown in figure 7.12. Being a low pass filter, Wiener filtering does tend to blur edges and high frequency components of the image. But it does a far better job than using a low pass blurring filter. We can achieve very good results for noise where the variance is not as high as that in our current image. >> t2=imnoise(t,’gaussian’,0,0.005); >> imshow(t2) >> t2w=wiener2(t2,[7,7]); >> figure,imshow(t2w) The image and its appearance after Wiener filtering as shown in figure 7.13. The result is a great improvement over the original noisy image. Exercises 1. The arrays below represent small greyscale images. Compute the  image that would result in each case if the middle   pixels were transformed using a    median filter:                                                                                           2.

NOISE Figure 7.13: Using Wiener filtering to remove Gaussian noise with low variance 4. Pratt [16] has proposed a “pseudo-median” filter, in order to overcome some of the speed disadvantages of the median filter. For example, given a five element sequence   , its pseudo-median is defined as psmed                              So for a sequence of length 5, we take the maxima and minima of all subsequences of length three. In general, for an odd-length sequence of length  , we take the maxima and minima of all subsequences of length  . We can apply the pseudo-median to    neighbourhoods of an image, or cross-shaped neighbourhoods containing 5 pixels, or any other neighbourhood with an odd number of pixels. Apply the pseudo-median to the images in question 1, using    neighbourhoods of each pixel. 5. Write a Matlab function to implement the pseudo-median, and apply it to the images above with the nlfilter function. Does it produce a good result? 6.

NOISE Chapter 8 Edges 8.1 Introduction Edges contain some of the most useful information in an image. We may use edges to measure the size of objects in an image; to isolate particular objects from their background; to recognize or classify objects. There are a large number of edge-finding algorithms in existence, and we shall look at some of the more straightforward of them. The general Matlab command for finding edges is edge(image,’method’,parameters. . . ) where the parameters available depend on the method used. In this chapter, we shall show how to create edge images using basic filtering methods, and discuss the Matlab edge function. An edge may be loosely defined as a line of pixels showing an observable difference. For example, consider the two blocks of pixels shown in figure 8.1. 51 52 53 59 54 52 53 62 50 52 53 68 55 52 53 55 50 53 150 160 51 53 150 170 52 53 151 190 51 53 152 155 Figure 8.1: Blocks of pixels In the right hand block, there is a clear difference between the grey values in the second and third columns. This would be easily discernable in an image—the human eye can pick out grey differences of this magnitude with relative ease. Our aim is to develop methods which will enable us to pick out the edges of an image. 8.2 Differences and edges 8.2.1 Fundamental definitions Suppose we follow the grey values of pixels in a line crossing an edge, as illustrated in figure 8.2. If we consider the grey values along this line, and plot their values, we will have something similar to that shown in figure 8.3 (a) or (b). If we now plot the differences between each grey value and its predecessor from the ramp edge, we would obtain a graph similar to that shown in figure 8.4. 111 112 CHAPTER 8. EDGES Figure 8.2: A line crossing an edge   (a) A “step” edge    (b) A “ramp” edge    (c) A line    (d) A “roof” Figure 8.3: Grey values across edges    Figure 8.4: Differences of the e 8.2. DIFFERENCES AND EDGES 113 To see where this graph comes from, suppose that the values of the “ramp” edge in figure 8.3(b) are, from left to right:        If we form the differences, by subtracting each value from its successor, we obtain: and it is these values which are plotted in figure 8.4. It appears that the difference tends to enhance edges, and reduce other components. So if we could “difference” the image, we would obtain the effect we want. We can define the difference in three separate ways: the forward difference:               , the backward difference:                , the central difference:                 . However, an image is a function of two variables, so we can generalize these definitions to include both the  and  values:                                                                                                               where the subscripts in each case indicate the direction of the difference. 8.2.2 Some difference filters To see how we might use  to determine edges in the  direction, consider the function values around a point    (and using the convention that  values increase to the right,  values to the bottom):                                                                To find the filter which returns the value  , we just compare the coefficients of the function’s values in  with their position in the array:       This filter thus will find vertical edges in an image and produce a reasonably bright result. However, the edges in the result can be a bit “jerky”; this can be overcome by smoothing the result in the opposite directio 114 CHAPTER 8. EDGES Both filters can be applied at once, using the combined filter:              This filter, and its companion for finding horizontal edges:             are the Prewitt filters for edge detection. We are now in the position of having to apply two filters to an image. The trick here is to apply each filter independently, and form the output image from a function of the filter values produced. So if  and were the grey values produced by applying  and to an image, then the output grey value can be chosen by any of these methods: 1.       , 2.     , 3.    . For example, let us take the image of the integrated circuit shown in figure 8.5, which can be read into Matlab with >> ic=imread(’ic.tif’); Figure 8.5: An integrated circuit Applying each of  and individually provides the results shown in figure 8.6 Figure 8.6(a) was produced with the foll 8.2. DIFFERENCES AND EDGES 115 (a) (b) Figure 8.6: The circuit after filtering with the Prewitt filters >> px=[-1 0 1;-1 0 1;-1 0 1]; >> icx=filter2(px,ic); >> figure,imshow(icx/255) and figure 8.6(b) with >> py=px’; >> icy=filter2(py,ic); >> figure,imshow(icy/255) Note that the filter  highlights vertical edges, and horizontal edges. We can create a figure containing all the edges with: >> edge_p=sqrt(icx.^2+icy.^2); >> figure,imshow(edge_p/255) and the result is shown in figure 8.7(a). This is a grey-scale image; a binary image containing edges only can be produced by thresholding. Figure 8.7(b) shows the result after the command >> edge_t=im2bw(edge_p/255,0.3); We can obtain edges by the Prewitt filters directly by using the command >> edge_p=edge(ic,’prewitt’); and the edge function takes care of all the filtering, and of choosing a suitable threshold level; see its help text for more information. The result is shown in figure 8.8. Note that figures 8.7(b) and 8.8 seem different to each other. This is because the edge function does some extra processing over and above taking the square root of the sum of the squares of the filter 116 CHAPTER 8. EDGES (a) (b) Figure 8.7: All the edges of the circuit Figure 8.8: The prewitt option of edge 8.2. DIFFERENCES AND EDGES 117 Slightly different edge finding filters are the Roberts cross-gradient filters:       and       and the Sobel filters:           and           The Sobel filters are similar to the Prewitt filters, in that they apply a smoothing filter in the opposite direction to the central difference filter. In the Sobel filters, the smoothing takes the form   which gives slightly more prominence to the central pixel. Figure 8.9 shows the respective results of the Matlab commands >> edge_r=edge(ic,’roberts’); >> figure,imshow(edge_r) and >> edge_s=edge(ic,’sobel’); >> figure,imshow(edge_s) (a) Roberts edge detection (b) Sobel edge detection Figure 8.9: Results of the Roberts and Sobel filters The appearance of each of these can be changed by specifying a threshold level. Of the three filters, the Sobel filters are probably the best; they provide good edges, and they perform reasonably well 118 CHAPTER 8. EDGES 8.3 Second differences 8.3.1 The Laplacian Another class of edge-detection method is obtained by considering the difference of differences; these are called second differences. To calculate a (central) second difference, take the backward difference of a forward difference:                                                                    This can be implemented by the filter        The corresponding filter for second differences  in the  direction is        The sum of these two is written    and is implemented by the filter          This is known as a discrete Laplacian. To see how the second difference affects an edge, take the difference of the pixel values as plotted in figure 8.4; the results are shown in figure 8.10.    Figure 8 8.3. SECOND DIFFERENCES 119 We see that the Laplacian (after taking an absolute value, or squaring) gives double edges. It is also extremely sensitive to noise. However, the Laplacian does have the advantage of detecting edges in all directions equally well. To see an example, suppose we enter the Matlab commands: >> l=fspecial(’laplacian’,0); >> ic_l=filter2(l,ic); >> figure,imshow(mat2gray(ic_l)) the result of which is shown in figure 8.11. Figure 8.11: Result after filtering with a discrete laplacian Although the result is adequate, it is very messy when compared to the results of the Prewitt and Sobel methods discussed earlier. Other Laplacian masks can be used; some are:             and             In Matlab, Laplacians of all sorts can be generated using the fspecial function, in the form fspecial(’laplacian’,ALPHA) which produces the Laplacian                If the parameter ALPHA (which is optional) is omitted, it is assumed to be  . The value gives the Laplacian de 120 CHAPTER 8. EDGES 8.3.2 Zero crossings A more appropriate use for the Laplacian is to find the position of edges by locating zero crossings. If we look at figure 8.10, we see that the position of the edge is given by the place where the value of the filter takes on a zero value. In general, these are places where the result of the filter changes sign. For example, consider the the simple image given in figure 8.12(a), and the result after filtering with a Laplacian mask in figure 8.12(b).                                                                                                                                                                                                                                                            (a) A simple image (b) After laplace filtering Figure 8.12: Locating zero crossings in an image We define the zero crossings in such a filtered image to be pixels which satisfy either of the following: 1. they have a negative grey value and are next to (by four-adjacency) a pixel whose grey value is positive, 2. they have a value of zero, and are between negative and positive valued pixels. To give an indication of the way zero-crossings work, look at the edge plots and their second differences in figure 8.13. In each case the zero-crossing is circled. The important point is to note that across any edge there can be only one zero-crossing. Thus an image formed from zero-crossings has the potential to be very neat. In figure 8.12(b) the zero crossings are shaded. We now have a further method of edge detection: take the zero-crossings after a laplace filtering. This is implemented in Matlab with the zerocross option of edge, which takes the zero crossings after filtering with a given filter: >> l=fspecial(’laplace’,0); >> icz=edge(ic,’zerocross’,l); >> imshow(icz) The result is shown in figure 8.14(a). We see that this is not in fact a very good result—far too many grey level changes have been interpreted as edges by this method. To eliminate them, we may fir 8.3.

This method was designed to provide a edge detection method to be as close as possible to biological vision. The first two steps can be combined into one, to produce a “Laplacian of Gaussian” or “LoG” filter. These filters can be created with the fspecial function. If no extra parameters are provided to the zerocross edge option, then the filter is chosen to be the LoG filter found by >> fspecial(’log’,13,2) This means that the following command: >> edge(ic,’log’); produces exactly the same result as the commands: >> log=fspecial(’log’,13,2); >> edge(ic,’zerocross’,log); In fact the LoG and zerocross options implement the same edge finding method; the difference being that the zerocross option allows you to specify your own filter. The result after applying an LoG filter and finding its zero crossings is given in fig 122 CHAPTER 8. EDGES (a) Zeros crossings (b) Using an LoG filter first Figure 8.14: Edge detection using zero crossings 8.4 Edge enhancement So far we have seen how to isolate edges in an image. A related operation is to make edges in an image slightly sharper and crisper, which generally results in an image more pleasing to the human eye. The operation is variously called “edge enhancement”, “edge crispening”, or “unsharp masking”. This last term comes from the printing industry. Unsharp masking The idea of unsharp masking is to subtract a scaled “unsharp” version of the image from the original. In practice, we can achieve this affect by subtracting a scaled blurred image from the original. The schema for unsharp masking is shown in figure 8.15. Original Blur with low pass filter Scale with   Subtract Scale for display Figure 8.15: Schema for unsharp masking Suppose we have an image x of type uint8. The we can apply unsharp masking by the following sequence of commands: >> f=fspecial(’average’); >> xf=filter2(f,x); >> xu=double(x)-xf/1. 8.4. EDGE ENHANCEMENT 123 >> imshow(xu/70) The last command scales the result so that imshow displays an appropriate image; the value may need to be adjusted according to the input image. Suppose that x is the image shown in figure 8.16(a), then the result of unsharp masking is given in figure 8.16(b). The result appears to be a better image than the original; the edges are crisper and more clearly defined. (a) Original image (b) The image after unsharp masking Figure 8.16: An example of unsharp masking To see why this works, we may consider the function of grey values as we travel across an edge, as shown in figure 8.17. As a scaled blur is subtracted from the original, the result is that the edge is enhanced, as shown in graph (c) of figure 8.17. We can in fact perform the filtering and subtracting operation in one command, using the linearity of the filter, and that the    filter     is the “identity filter”. Hence unsharp masking can be implemented by a filter of the form                    where is a constant chosen to provide the best result. Alternatively, the unsharp masking filter may be defined as                   so that we are in effect subtracting a blur from a scaled version of the original; the scaling fac 124 CHAPTER 8.

Notice in particular the rocks and trees in the background, and the ripples on the water. (a) The original (b) After unsharp masking Figure 8.18: Edge enhancement with unsharp masking Although we have used averaging filters above, we can in fact use any low pass filter for unsharp masking.

If  , then the high boost filter becomes an ordinary high pass filter. If we take as the low pass filter the    averaging filter, then a high boost filter will have the form                     where  . If we put   , we obtain a filtering very similar to the unsharp filter above, except for a scaling factor. Thus the commands: >> f=[-1 -1 -1;-1 11 -1;-1 -1 -1]/9; >> xf=filter2(x,f); >> imshow(xf/80) will produce an image similar to that in figure 8.16.

EDGES 8.5 Final Remarks As we have seen there are a great many different edge detection algorithms; we have only looked at those which are implemented in the edge function of the Matlab image Processing Toolbox. There are, however, a vast number of further algorithms and methods in existence. Most of them can be programmed as Matlab programs with little effort. As to which method is the best; like so many image processing tasks, this is highly subjective. The choice of an suitable edge detector will depend very much on the nature of the image, the amount (and type) of noise, and the use for which the edges are to be put. Exercises 1.

EDGES Chapter 9 The Fourier Transform 9.1 Introduction The Fourier Transform is of fundamental importance to image processing. It allows us to perform tasks which would be impossible to perform any other way; its efficiency allows us to perform other tasks more quickly. The Fourier Transform provides, among other things, a powerful alternative to linear spatial filtering; it is more efficient to use the Fourier transform than a spatial filter for a large filter. The Fourier Transform also allows us to isolate and process particular image “frequencies”, and so perform low-pass and high-pass filtering with a great degree of precision. Before we discuss the Fourier transform of images, we shall investigate the one-dimensional Fourier transform, and a few of its properties. 9.2 The one-dimensional discrete Fourier transform Our starting place is the observation that a periodic function may be written as the sum of sines and cosines of varying amplitudes and frequencies. For example, in figure 9.1 we show a function, and its decomposition into sine functions. Some functions will require only a finite number of functions in their decomposition; others will require an infinite number. For example, a “square wave”, such as is shown in figure 9.2, has the decomposition                       (9.1) In figure 9.2 we take the first four terms only to provide the approximation. The more terms of the series we take, the closer the sum will approach the original function. When we deal with a discrete function, as we shall do for images, the situation changes slightly. Since we only have to obtain a finite number of values, we only need a finite number of functions to do it. Consider for example the discrete sequence             which we may take as a discrete approximation to the square wave of figure 9.2. This can be expressed as the sum of only two sine functions; this is shown in figure 9.3. We shall see below how to obtain those sequenc 132 CHAPTER 9. THE FOURIER TRANSFORM                         Figure 9.1: A function and its trigonometric decomposition                   Figure 9.2: A square wave and its trigo 9.2. THE ONE-DIMENSIONAL DISCRETE FOURIER TRANSFORM 133 Figure 9.3: Expressing a discrete function as the sum of sines 134 CHAPTER 9. THE FOURIER TRANSFORM The Fourier transform allows us to obtain those individual sine waves which compose a given function or sequence. Since we shall bne concerend with discrete sequences, and of course images, we shall investigate only the discrete Fourier transform, abbreviated DFT. 9.2.1 Definition of the one dimensional DFT Suppose          is a sequence of length . We define its discrete Fourier transform to be the sequence         where    0 2    #     (9.2) The inverse DFT The formula for the inverse DFT is very similar to the forward transform:  0 2   #     (9.3) If you compare this equation with equation 9.2 you will see that there are really only two differences: 1. there is no scaling factor , 2. the sign inside the exponential function has been changed to positive. In Matlab, we can calculate the forward and inverse transforms with fft and ifft. Here fft stands for Fast Fourier Transform, which is a fast and efficient method of performing the DFT (see below for details). For example: a = 1 2 3 4 5 6 >> fft(a’) ans = 21.0000 -3.0000 + 5.1962i -3.0000 + 1.7321i -3.0000 -3.0000 - 1.7321i -3.0000 - 5.1962i We note that to apply a DFT to a single vector in Matlab, we should use a column 9.3. PROPERTIES OF THE ONE-DIMENSIONAL DFT 135 9.3 Properties of the one-dimensional DFT The one-dimensional DFT satisfies many useful and important properties. We will investigate some of them here. A more complete list can be found in, for example [9]. Linearity. This is a direct consequence of the definition of the DFT as a matrix product. Suppose and  are two vectors of equal length, and and are scalars, with . If ,  and  are the DFT’s of ,  and respectively, we have     This follows from the definitions of      and the linearity of the matrix product. Shifting. Suppose we multiply each element  of a vector  by      . In other words, we change the sign of every second element. Let the resulting vector be denoted  . The the DFT  of  is equal to the DFT  of  with the swapping of the left and right halves. Let’s do a quick Matlab example: >> x = [2 3 4 5 6 7 8 1]; >> x1=(-1).^[0:7].*x x1 = 2 -3 4 -5 6 -7 8 -1 >> X=fft(x’) 36.0000 -9.6569 + 4.0000i -4.0000 - 4.0000i 1.6569 - 4.0000i 4.0000 1.6569 + 4.0000i -4.0000 + 4.0000i -9.6569 - 4.0000i >> X1=fft(x1’) X1 = 4.0000 1.6569 + 4.0000i -4.0000 + 4.0000i -9.65 136 CHAPTER 9. THE FOURIER TRANSFORM 36.0000 -9.6569 + 4.0000i -4.0000 - 4.0000i 1.6569 - 4.0000i Notice that the first four elements of X are the last four elements of X1, and vice versa. Conjugate symmetry If  is real, and of length , then its DFT  satisfies the condition that    where   is the complex conjugate of   , for all         . So in our example of length 8, we have    In this case we also have   , which means  must be real. In fact if  is even, then    will be real. Examples can be seen above. The Fast Fourier Transform. Without an efficient method of calculating a DFT, it would remain only of academic interest, and of no practical use. However, there are a number of extremely fast and efficient algorithms for computing a DFT; such an algorithm is called a fast Fourier transform, or FFT. The use of an FFT vastly reduces the time needed to compute a DFT. One FFT method works recursively by dividing the original vector into two halves, computing the FFT of each half, and then putting the results together. This means that the FFT is most efficient when the vector length is a power of 2. Table 9.1 shows that advantage gained by using the FFT algorithm as opposed to the direct arithmetic definition of equations 9.6 and 9.7 by comparing the number of multiplications required for each method. For a vector of length  , the direct method takes      multiplications; the FFT only  . The saving in time is thus of an order of  . Clearly the advantage of using an FFT algorithm becomes greater as the size of the vector increases. Because of the this computational advantage, any implementation of the DFT will use an FFT algorithm.

THE TWO-DIMENSIONAL DFT 137 9.4 The two-dimensional DFT In two dimensions, the DFT takes a matrix as input, and returns another matrix, of the same size, as output. If the original matrix values are      , where  and  are the indices, then the output matrix values are   . We call the matrix  the Fourier transform of  and write      Then the original matrix  is the inverse Fourier transform of , and we write     We have seen that a (one-dimensional) function can be written as a sum of sines and cosines. Given that an image may be considered as a two-dimensional function      , it seems reasonable to assume that  can be expressed as sums of “corrugation” functions which have the general form       A sample such function is shown in figure 9.4. And this is in fact exactly what the two-dimensional 2 4 6 8 10 12 14 2 4 6 8 10 12 14 0.5 1 1.5 2 Figure 9.4: A “corrugation” function Fourier transform does: it rewrites the original matrix in terms of sums of corrugations. We can be more precise here: the magnitude of the fourier transform is a matrix (the same size as the starting matrix) whose elements  give the height of the corrugation for which the horizontal and vertical distances between consecutive troughs are   and  . This is shown in figure 9.5. The definition of the two-dimensional discrete Fourier transform is very similar to that for one dimension. The forward and inverse transforms for an    matrix, where for notational convenience we assume that the  indices are from 0 to    and the  indices are from to    , are:    0 2  0 2         #       (9.4)        0 2  0 2    #       (9.5) These are horrendous looking formulas, but if we spend a bit of time pulling them apart, we shall see that they aren 138 CHAPTER 9. THE FOURIER TRANSFORM    Figure 9.5: Corrugations and their measurements Before we do this, we note that the formulas given in equations 9.4 and 9.5 are not used by all authors. The main change is the position of the scaling factor . Some people put it in front of the sums in the forward formula. Others put a factor of   in front of both sums. The point is the sums by themselves would produce a result (after both forward and inverse transforms) which is too large by a factor of . So somewhere in the forward-inverse formulas a corresponding  must exist; it doesn’t really matter where. 9.4.1 Some properties of the two dimensional Fourier transform All the properties of the one-dimensional DFT transfer into two dimensions. But there are some further properties not previously mentioned, which are of particular use for image processing. Similarity. First notice that the forward and inverse transforms are very similar, with the exception of the scale factor  in the inverse transform, and the negative sign in the exponent of the forward transform. This means that the same algorithm, only very slightly adjusted, can be used for both the forward an inverse transforms. The DFT as a spatial filter. Note that the values  #      are independent of the values  or . This means that they can be calculated in advance, and only then put into the formulas above. It also means that every value   is obtained by multiplying every value of     by a fixed value, and adding up all the results. But this is precisely what a linear spatial filter does: it multiplies all elements under a mask with fixed values, an 9.4. THE TWO-DIMENSIONAL DFT 139 all up. Thus we can consider the DFT as a linear spatial filter which is as big as the image. To deal with the problem of edges, we assume that the image is tiled in all directions, so that the mask always has image values to use. Separability. Notice that the Fourier transform “filter elements” can be expressed as products:  #       #    #    The first product value  #   depends only on  and , and is independent of  and . Conversely, the second product value  #   depends only on  and , and is independent of  and . This means that we can break down our formulas above to simpler formulas that work on single rows or columns:    0 2        #   (9.6)       0 2     #    (9.7) If we replace  and with  and we obtain the corresponding formulas for the DFT of matrix columns. These formulas define the one-dimensional DFT of a vector, or simply the DFT. The 2-D DFT can be calculated by using this property of “separability”; to obtain the 2-D DFT of a matrix, we first calculate the DFT of all the rows, and then calculate the DFT of all the columns of the result, as shown in figure 9.6. Since a product is independent of the order, we can equally well calculate a 2-D DFT by calculating the DFT of all the columns first, then calculating the DFT of all the rows of the result. (a) Original image (b) DFT of each row of (a) (c) DFT of each column of (b) Figure 9.6: C 140 CHAPTER 9. THE FOURIER TRANSFORM Linearity An important property of the DFT is its linearity; the DFT of a sum is equal to the sum of the individual DFT’s, and the same goes for scalar multiplication:               where is a scalar, and  and are matrices. This follows directly from the definition given in equation 9.4. This property is of great use in dealing with image degradation such as noise which can be modelled as a sum:   where  is the original image; is the noise, and  is the degraded image. Since         we may be able to remove or reduce by modifying the transform. As we shall see, some noise appears on the DFT in a way which makes it particularly easy to remove. The convolution theorem. This result provides one of the most powerful advantages of using the DFT. Suppose we wish to convolve an image  with a spatial filter . Our method has been place over each pixel of  in turn, calculate the product of all corresponding grey values of  and elements of , and add the results. The result is called the digital convolution of  and , and is denoted   This method of convolution can be very slow, especially if is large. The convolution theorem states that the result  can be obtained by the following sequence of steps: 1. Pad with zeroes so that is the same size as ; denote this padded result by . 2. Form the DFT’s of both  and , to obtain  and   . 3. Form the element-by-element product of these two transforms:      4. Take the inverse transform of the result:         Put simply, the convolution theorem states:         or equivalently that        Although this might seem like an unnecessarily clumsy and roundabout way of computing something so simple as a convolution, it can have e 9.4. THE TWO-DIMENSIONAL DFT 141 For example, suppose we wish to convolve a    image with a   filter. To do this directly would require    multiplications for each pixel, of which there are      . Thus there will be a total of         multiplications needed. Now look at applying the DFT (using an FFT algorithm). Each row requires 4608 multiplications by table 9.1; there are 512 rows, so a total of       multiplications; the same must be done again for the columns. Thus to obtain the DFT of the image requires    multiplications. We need the same amount to obtain the DFT of the filter, and for the inverse DFT. We also require    multiplications to perform the product of the two transforms. Thus the total number of multiplications needed to perform convolution using the DFT is           which is an enormous saving compared to the direct method. The DC coefficient. The value   of the DFT is called the DC coefficient. If we put in the definition given in equation 9.4 we find that    0 2  0 2          0 2  0 2        That is, this term is equal to the sum of all terms in the original matrix. Shifting. For purposes of display, it is convenient to have the DC coefficient in the centre of the matrix. This will happen if all elements      in the matrix are multiplied by      before the transform. Figure 9.7 demonstrates how the matrix is shifted by this method. In each diagram the DC coefficient is the top left hand element of submatrix , and is shown as a black square. ! " An FFT " ! After shifting Figure 9.7: Shifting a DFT Conjugate symmetry An analysis of the Fourier transform definition leads to a symmetry property; if we make the substitutions  and  in equation 9.4 then we find that         for any integers and . This means that half of the transform is a mirror image of the conjugate of the other half. We can think of the top and bottom halves, or the left and right halves, being mirror images of the conjugates of each other. Figure 9.8 demonstrates this symmetry in a shifted DFT. As with figure 9.7, the black square shows the position of the DC coefficient. The symmetry means that its information is giv 142 CHAPTER 9. THE FOURIER TRANSFORM  ! !  Figure 9.8: Conjugate symmetry in the DFT Displaying transforms. Having obtained the Fourier transform   of an image     , we would like to see what it looks like. As the elements    are complex numbers, we can’t view them directly, but we can view their magnitude     . Since these will be numbers of type double, generally with large range, we have two approaches 1. find the maximum value  of      (this will be the DC coefficient), and use imshow to view     , 2. use mat2gray to view     directly. One trouble is that the DC coefficient is generally very much larger than all other values. This has the effect of showing a transform as a single white dot surrounded by black. One way of stretching out the values is to take the logarithm of     and to display           The display of the magnitude of a Fourier transform is called the spectrum of the transform. We shall see some examples later on. 9.5 Fourier transforms in Matlab The relevant Matlab functions for us are: fft which takes the DFT of a vector, ifft which takes the inverse DFT of a vector, fft2 which takes the DFT of a matrix, ifft2 which takes the inverse DFT of a matrix, fftshift which shifts a transform as shown in figure 9.7. of which we have seen the first two above. Before attacking a few images, let’s take the Fourier transform of a few small matrices to get more of a 9.5. FOURIER TRANSFORMS IN MATLAB 143 Example 1. Suppose we take a constant matrix       . Going back to the idea of a sum of corrugations, we see that in fact no corrugations are required to form a constant. Thus we would hope that the DFT consists of a DC coefficient and zeroes everywhere else. We will use the ones function, which produces an  matrix consisting of  ’s, where is an input to the function. >> a=ones(8); >> fft2(a) The result is indeed as we expected: ans = 64 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 Note that the DC coefficient is indeed the sum of all the matrix values.

Now we’ll take a matrix consisting of a single corrugation: >> a = [100 200; 100 200]; >> a = repmat(a,4,4) ans = 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 100 200 >> af = fft2(a) ans = 9600 0 0 0 -3200 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 144 CHAPTER 9. THE FOURIER TRANSFORM What we have here is really the sum of two matrices: a constant matrix each element of which is   , and a corrugation which alternates   and  from left to right. The constant matrix alone would produce (as in example 1), a DC coefficient alone of value      ; the corrugation a single value. By linearity, the DFT will consist of just the two values. Example 3. We will take here a single step edge: >> a = [zeros(8,4) ones(8,4)] a = 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 0 1 1 1 1 Now we shall perform the Fourier transform with a shift, to place the DC coefficient in the centre, and since it contains some complex values, for simplicity we shall just show the rounded absolute values: >> af=fftshift(fft2(a)); >> round(abs(af)) ans = 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 9 0 21 32 21 0 9 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 The DC coefficient is of course the sum of all values of a; the other values may be considered to be the coefficients of the necessary sine functions required to from an edge, as given in equation 9.1. The mirroring of values about the DC coefficient is a consequence of the symmetry of the DFT. 9.6 Fourier transforms of images We shall create a few simple images, and see what the Fourier transform produces. Example 1. We shall produce a simple image consisting of a single edge: >> a=[zeros(256,128) ones(25 9.6. FOURIER TRANSFORMS OF IMAGES 145 This is displayed on the left in figure 9.10. Now we shall take its DFT, and shift it: >> af=fftshift(fft2(a)); Now we’ll view its spectrum; we have the choice of two commands: 1. afl=log(1+abs(af)); imshow(afl/afl(129,129)) This works because after shifting, the DC coefficient is at position   ,   . We stretch the transform using log, and divide the result by the middle value to obtain matrix of type double with values in the range –  . This can then be viewed directly with imshow. 2. imshow(mat2gray(log(1+abs(af)))) The mat2gray function automatically scales a matrix for display as an image, as we have seen in chapter 6 It is in fact convenient to write a small function for viewing transforms. One such is shown in figure 9.9. Then for example >> fftshow(af,’log’) will show the logarithm of the absolute values of the transform, and >> fftshow(af,’abs’) will show the absolute values of the transform without any scaling. The result is shown on the right in figure 9.10. We see immediately that the result is similar (although larger) to example 3 in the previous section. Example 2. Now we’ll create a box, and then its Fourier transform: >> a=zeros(256,256); >> a(78:178,78:178)=1; >> imshow(a) >> af=fftshift(fft2(a)); >> figure,fftshow(af,’abs’) The box is shown on the left in figure 9.11, and its Fourier transform is is shown on the right. Example 3. Now we shall look at a box rotated  . >> [x,y]=meshgrid(1:256,1:256); >> b=(x+y<329)&(x+y>182)&(x-y>-67)&(x-y<73); >> imshow(b) >> bf=fftshift(fft2(b)); >> figure,fftshow(bf) The results are shown in figure 9.12. Note that the transform of the rotated box is the rotated transform of the ori 146 CHAPTER 9.

We will create a small circle, and then transform it: >> [x,y]=meshgrid(-128:217,-128:127); >> z=sqrt(x.^2+y.^2); >> c=(z<15); The result is shown on the left in figure 9.13. Now we will create its Fourier transform and display it: >> cf=fft2shift(fft2(z)); >> fftshow(cf,’log’) and this is shown on the right in figure 9.13. Note the “ringing” in the Fourier transform. This is an artifact associated with the sharp cutoff of the circle. As we have seen from both the edge and box images in the previous examples, an edge appears in the transform as a line of values at right angles to the edge. We may consider the values on the line as being the coefficients of the appropriate corrugation functions which sum to the edge. With the circle, we have lines of values radiating out from the circle; these values appear as circles in the transform. A circle with a gentle cutoff, so that its edge appears blurred, will have a transform with no ringing. Such a circle can be made with the command (given z above): b=1./(1+(z./15).^2); This image appears as a blurred circle, and its transform is very similar—check them out! 9.7 Filtering in the frequency domain We have seen in section 9.4 that one of the reasons for the use of the Fourier transform in image processing is due to the convolution theorem: a spatial convolution can be performed by elementwise multiplication of the Fourier transform by a suitable “filter matrix”. In this section we shall explore some filtering by this method. 9.7. FILTERING IN THE FREQUENCY DOMAIN 149 Figure 9.13: A circle and its DFT 9.7.1 Ideal filtering Low pass filtering Suppose we have a Fourier transform matrix , shifted so that the DC coefficient is in the centre. Since the low frequency components are towards the centre, we can perform low pass filtering by multiplying the transform by a matrix in such a way that centre values are maintained, and values away from the centre are either removed or minimized. One way to do this is to multiply by an ideal low-pass matrix, which is a binary matrix  defined by:     if     is closer to the center than some value if     is further from the center than  The circle c displayed in figure 9.13 is just such a matrix, with  . Then the inverse Fourier transform of the element-wise product of  and  is the result we require:      Let’s see what happens if we apply this filter to an image. First we obtain an image and its DFT. >> cm=imread(’cameraman.tif’); >> cf=fftshift(fft2(cm)); >> figure,fftshow(cf,’log’) The cameraman image and its DFT are shown in figure 9.14. Now we can perform a low pass filter by multiplying the transform matrix by the circle matrix (recall that “dot asterisk” is the Matlab syntax for element-wise multiplication of two matrices): >> cfl=cf.*c; >> figure,fftshow(cfl,’log’) and this is shown in figure 9.15(a). Now we can take the inverse transform and display the r 150 CHAPTER 9. THE FOURIER TRANSFORM Figure 9.14: The “cameraman” image and its DFT >> cfli=ifft2(cfl); >> figure,fftshow(cfli,’abs’) and this is shown in figure 9.15(b). Note that even though cfli is supposedly a matrix of real numbers, we are still using fftshow to display it. This is because the fft2 and fft2 functions, being numeric, will not produce mathematically perfect results, but rather very close numeric approximations. So using fftshow with the ’abs’ option rounds out any errors obtained during the transform and its inverse. Note the “ringing” about the edges in this image. This is a direct result (a) Ideal filtering on the DFT (b) After inversion Figure 9.15: Applying ideal low pass filtering of the sharp cutoff of the circle. The ringing as shown in figure 9.13 is transferred to the image. 9.7. FILTERING IN THE FREQUENCY DOMAIN 151 We would expect that the smaller the circle, the more blurred the image, and the larger the circle; the less blurred. Figure 9.16 demonstrates this, using cutoffs of 5 and 30. Notice that ringing (a) Cutoff of 5 (b) Cutoff of 30 Figure 9.16: Ideal low pass filtering with different cutoffs is still present, and clearly visible in figure 9.16(b). High pass filtering Just as we can perform low pass filtering by keeping the centre values of the DFT and eliminating the others, so high pass filtering can be performed by the opposite: eliminating centre values and keeping the others. This can be done with a minor modification of the preceding method of low pass filtering. First we create the circle: >> [x,y]=meshgrid(-128:127,-128:127); >> z=sqrt(x.^2+y.^2); >> c=(z>15); and the multiply it by the DFT of the image: >> cfh=cf.*c; >> figure,fftshow(cfh,’log’) This is shown in figure 9.17(a). The inverse DFT can be easily produced and displayed: >> cfhi=ifft2(cfh); >> figure,fftshow(cfhi,’abs’) and this is shown in figure 9.17(b). As with low pass filtering, the size of the circle influences the information available to the inverse DFT, and hence the final result. Figure 9.18 shows some results of ideal high pass filtering with different cutoffs. If the cutoff is large, then more information is removed from the transform, leaving only the highest frequencies. We see this in figure 9.18(c) and (d); only the edges of the image remain. If we have small cutoff, such as in figure 9.18(a), we 152 CHAPTER 9. THE FOURIER TRANSFORM (a) The DFT after high pass filtering (b) The resulting image Figure 9.17: Applying an ideal high pass filter to an image are only removing a small amount of the transform. We would thus expect that only the lowest frequencies of the image would be removed. And this is indeed true, as we see in figure 9.18(b); there is some greyscale detail in the final image, but large areas of low frequency are close to zero. 9.7.2 Butterworth filtering Ideal filtering simply cuts off the Fourier transform at some distance from the centre. This is very easy to implement, as we have seen, but has the disadvantage of introducing unwanted artifacts: ringing, into the result. One way of avoiding this is to use as a filter matrix a circle with a less sharp cutoff. A popular choice is to use Butterworth filters. Before we describe these filters, we shall look again at the ideal filters. As these are radially symmetric about the centre of the transform, they can be simply described in terms of their cross sections. That is, we can describe the filter as a function of the distance  from the centre. For an ideal low pass filter, this function can be expressed as      if    if  where is the cutoff radius. Then the ideal high pass filters can be described similarly:      if   if   These functions are illustrated in figure 9.19. Butterworth filter functions are based on the following functions for low pass filters:           and for high pass filters:     9.7.

THE FOURIER TRANSFORM             (a) Low pass (b) High pass Figure 9.19: Ideal filter functions where in each case the parameter is called the order of the filter. The size of dictates the sharpness of the cutoff. These functions are illustrated in figures 9.20 and 9.21.             (a) Low pass (b) High pass Figure 9.20: Butterworth filter functions with  It is easy to implement these in Matlab; here are the commands to produce a Butterworth low pass filter of size    with   and order : >> [x,y]=meshgrid(-128:217,-128:127)); >> bl=1./(1+((x.^2+y.^2)/15).^2); Since a Butterworth high pass filter can be obtained by subtracting a low pass filter from 1, we can write general Matlab functions to generate Butterworth filters of general sizes. These are shown in figures 9.22 and 9.23. So to apply a Butterworth low pass filter to the DFT of the cameraman image: >> bl=lbutter(c,15,1); >> cfbl=cf.*bl; >> figure,fftshow(cfbl,’log’) and this is shown in figure 9.24(a). Note that there is no sharp cutoff as seen in figure 9 9.7.

THE FOURIER TRANSFORM the outer parts of the transform are not equal to zero, although they are dimmed considerably. Performing the inverse transform and displaying it as we have done previously produces figure 9.24(b). This is certainly a blurred image, but the ringing seen in figure 9.15 is completely absent. Compare (a) The DFT after Butterworth low pass filtering (b) The resulting image Figure 9.24: Butterworth low pass filtering the transform after multiplying with a Butterworth filter (figure 9.24(a)) with the original transform (in figure 9.14). We see that the Butterworth filter does cause an attenuation of values away from the centre, even if they don’t become suddenly zero, as with the ideal low pass filter in figure 9.15. We can apply a Butterworth high pass filter similarly, first by creating the filter and applying it to the image transform: >> bh=hbutter(cm,15,1); >> cfbh=cf.*bh; >> figure,fftshow(cfbh,’log’) and then inverting and displaying the result: >> cfbhi=ifft2(cfbh); >> figure,fftshow(cfbhi,’abs’) The images are shown in figure 9.25 9.7.3 Gaussian filtering We have met Gaussian filters in chapter 6, and we saw that they could be used for low pass filtering. However, we can also use Gaussian filters in the frequency domain. As with ideal and Butterworth filters, the implementation is very simple: create a Gaussian filter, multiply it by the image transform, and invert the result. Since Gaussian filters have the very nice mathematical property that a Fourier transform of a Gaussian is a Gaussian, we should get exactly the same results as when using a linear Gaussian spatial filter. 9.7. FILTERING IN THE FREQUENCY DOMAIN 157 (a) The DFT after Butterworth high pass filtering (b) The resulting image Figure 9.25: Butterworth high pass filtering Gaussian filters may be considered to be the most “smooth” of all the filters we have discussed so far, with ideal filters the least smooth, and Butterworth filters in the middle. We can create Gaussian filters using the fspecial function, and apply them to our transform. >> g1=mat2gray(fspecial(’gaussian’,256,10)); >> cg1=cf.*g1; >> fftshow(cg1,’log’) >> g2=mat2gray(fspecial(’gaussian’,256,30)); >> cg2=cf.*g2; >> figure,fftshow(cg2,’log’) Note the use of the mat2gray function. The fspecial function on its own produces a low pass Gaussian filter with a very small maximum: >> g=fspecial(’gaussian’,256,10); >> format long, max(g(:)), format ans = 0.00158757552679 The reason is that fspecial adjusts its output to keep the volume under the Gaussian function always 1. This means that a wider function, with a large standard deviation, will have a low maximum. So we need to scale the result so that the central value will be 1; and mat2gray does that automatically. The transforms are shown in figure 9.26(a) and (c). In each case, the final parameter of the fspecial function is the standard deviation; it controls the width of the filter. As we see, the larger the standard deviation, the wider the function, and so the greater amount of the transform is preserved. 158 CHAPTER 9. THE FOURIER TRANSFORM The results of the transform on the original image can be produced using the usual sequence of commands: >> cgi1=ifft2(cg1); >> cgi2=ifft2(cg2); >> fftshow(cgi1,’abs’); >> fftshow(cgi2,’abs’); and the results are shown in figure 9.26(b) and (d) (a)  (b) Resulting image (c)  (d) Resulting image Figure 9.26: Applying a Gaussian low pass filter in the frequency domain We can apply a high pass Gaussian filter easily; we create a high pass filter by subtracting a low pass filter f 9.8.

As with ideal and Butterworth filters, the wider the high (a) Using  (b) Using  Figure 9.27: Applying a Gaussian high pass filter in the frequency domain pass filter, the more of the transform we are reducing, and the less of the original image will appear in the result. 9.8 Removal of periodic noise In chapter 7 we investigated a number of different noise types which can affect images. However, we did not look at periodic noise. This may occur if the imaging equipment (the acquisition or networking hardware) is subject to electronic disturbance of a repeating nature, such as may be caused by an electric motor. We can easily create periodic noise by overlaying an image with a trigonometric function: >> [x,y]=meshgrid(1:256,1:256); >> s=1+sin(x+y/1.5); >> cp=(double(cm)/128+s)/4; where cm is the cameraman image from previous sections. The second line simply creates a sine function, and adjusts its output to be in the range 0–2. The last line first adjusts the cameraman image to be in the same range; adds the sine function to it, and divides by 4 to produce a mat 160 CHAPTER 9. THE FOURIER TRANSFORM type double with all elements in the range –  . This can be viewed directly with imshow, and it is shown in figure 9.28(a). We can produce its DFT: (a) (b) Figure 9.28: The cameraman image (a) with periodic noise, and (b) its transform >> cpf=fftshift(fft2(cp)); and this is shown in figure 9.28(b). The extra two “spikes” away from the centre correspond to the noise just added. In general the tighter the period of the noise, the further from the centre the two spikes will be. This is because a small period corresponds to a high frequency (large change over a small distance), and is therefore further away from the centre of the shifted transform. We will now remove these extra spikes, and invert the result. If we put pixval on and move around the image, we find that the spikes have row, column values of       and    . These have the same distance from the centre:   . We can check this by >> z(156,170) >> z(102,88) There are two methods we can use to eliminate the spikes, we shall look at both of them. Band reject filtering. We create a filter consisting of ones with a ring of zeroes; the zeroes lying at a radius of 49 from the centre: >> br=(z < 47 | z > 51); where z is the matrix consisting of distances from the origin. This particular ring will have a thickness large enough to cover the spikes. Then as before, we multiply this by the transform: >> cpfbr=cpf.*br and this is shown in figure 9.29(a). The result is that the spikes have been blocked out by this filter. Taking the inverse transform produces the image shown in figure 9.29(b). Note that not all the noise has gone, but a significant amount has, especially in the centre of t 9.9. INVERSE FILTERING 161 (a) A band-reject filter (b) After inversion Figure 9.29: Removing periodic noise with a band-reject filter Notch filtering. With a notch filter, we simply make the rows and columns of the spikes zero: >> cpf(156,:)=0; >> cpf(102,:)=0; >> cpf(:,170)=0; >> cpf(:,88)=0; and the result is shown in figure 9.30(a). The image after inversion is shown in figure 9.30(b). As before, much of the noise in the centre has been removed. Making more rows and columns of the transform zero would result in a larger reduction of noise. 9.9 Inverse filtering We have seen that we can perform filtering in the Fourier domain by multiplying the DFT of an image by the DFT of a filter: this is a direct use of the convolution theorem. We thus have           where is the DFT of the image;  is the DFT of the filter, and is the DFT of the result. If we are given and , then we should be able to recover the (DFT of the) original image simply by dividing by :            (9.8) Suppose, for example we take the wombats image wombats.tif, and blur it using a low-pass Butterworth filter: >> w=imread(’wombats.tif’); >> wf=fftshift 162 CHAPTER 9. THE FOURIER TRANSFORM (a) A notch filter (b) After inversion Figure 9.30: Removing periodic noise with a notch filter >> b=lbutter(w,15,2); >> wb=wf.*b; >> wba=abs(ifft2(wb)); >> wba=uint8(255*mat2gray(wba)); >> imshow(wba) The result is shown on the left in figure 9.31. We can attempt to recover the original image by dividing by the filter: >> w1=fftshift(fft2(wba))./b; >> w1a=abs(ifft2(w1)); >> imshow(mat2gray(w1a)) and the result is shown on the right in figure 9.31. This is no improvement! The trouble is that some elements of the Butterworth matrix are very small, so dividing produces very large values which dominate the output. We can deal with this problem in two ways: 1. Apply a low pass filter to the division:              This should eliminate very low (or zero) values. 2. “Constrained division”: choose a threshold value  , and if        , we don’t perform a division, but just keep our original value. Thus:              if       ,    if     9.9. INVERSE FILTERING 163 Figure 9.31: An attempt at inverse filtering We can apply the first method by multiplying a Butterworth low pass filter to the matrix c1 above: >> wbf=fftshift(fft2(wba)); >> w1=(wbf./b).*lbutter(w,40,10); >> w1a=abs(ifft2(w1)); >> imshow(mat2gray(w1a)) Figure 9.32 shows the results obtained by using a different cutoff radius of the Butterworth filter each time: (a) uses 40 (as in the Matlab commands just given); (b) uses 60; (c) uses 80, and (d) uses 100. It seems that using a low pass filter with a cutoff round about 60 will yield the best results. After we use larger cutoffs, the result degenerates. We can try the second method; to implement it we simply make all values of the filter which are too small equal to 1: >> d=0.01; >> b=lbutter(w,15,2);b(find(b> w1=fftshift(fft2(wba))./b; >> w1a=abs(ifft2(w1)); >> imshow(mat2gray(w1a)) Figure 9.33 shows the results obtained by using a different cutoff radius of the Butterworth filter each time: (a) uses    (as in the Matlab commands just given); (b) uses   ; (c) uses   , and (d) uses    . It seems that using a threshold  in the range       produces reasonable results. Motion deblurring We can consider the removal of blur caused by motion to be a special case of inverse filtering. Suppose we take an image and blur it by a small amount. >> bc=imread(’board.tif’); >> bg= 164 CHAPTER 9.

The result is shown as figure 9.34(a). To blur it, we can use the blur parameter of the fspecial function. >> m=fspecial(’motion’,7,0); >> bm=imfilter(b,m); >> imshow(bm) and the result is shown as figure 9.34(b). The result of the blur has effectively obliterated the text (a) (b) Figure 9.34: The result of motion blur on the image. To deblur the image, we need to divide its transform by the transform corresponding to the blur filter. This means that we first must create a matrix corresponding to the transform of the blur: >> m2=zeros(256,256); >> m2(1,1:7)=m; >> mf=fft2(m2); Now we can attempt to divide by this transform. >> bmi=ifft2(fft2(bm)./mf); >> fftshow(bmi,’abs’) and the result is shown in figure 9.35(a). As with inverse filtering, the result is not particularly good, because the values close to zero in the matrix mf have tended to dominate the result. As above, we can constrain the division by only dividing by values which are above a certain threshold. >> d=0.02; >> mf=fft2(m2);mf(find(abs(mf)> bmi=ifft2(fft2(bm)./mf); >> imshow(mat2gray(abs(bmi))*2) 9.9.

Chapter 10 The Hough and Distance Transforms 10.1 The Hough transform As we have mentioned in chapter 5, an image transform is an operation which takes an image, or the array of its pixel values, and “transforms” it into a different form. This new form is then processed to provide the result we require. Sometimes it is necessary to apply an inverse transform after the processing, to obtain the processed image. In this chapter we investigate two important transforms, with many different applications. The Hough transform1 is designed to find lines in images, but it can be easily varied to find other shapes. The idea is simple. Suppose     is a point in the image (which we shall assume to be binary). We can write   , and consider all pairs   which satisfy this equation, and plot them into an “accumulator array”. The   array is the “transform array”. For example, take         . Since the equation relating and is    we can write    Thus the line   consists of all pairs of points relating to the single point     . This is shown in figure 10.1.       Image  Transform Figure 10.1: A point in an image and its corresponding line in the transform Each point in the image is mapped onto a line in the transform. The points in the transform corresponding to the greatest number of intersections correspond to the strongest line in the image. 1 “Hough” is 170 CHAPTER 10. THE HOUGH AND DISTANCE TRANSFORMS For example, suppose we consider an image with five points:    ,     ,    ,    and    . Each of these points corresponds to a line as follows:                                Each of these lines appears in the transform as shown in figure 10.2.           Image  Transform Figure 10.2: An image and its corresponding lines in the transform The dots in the transform indicate places where there are maximum intersections of lines: at each dot three lines intersect. The coordinates of these dots are      and        . These values correspond to the lines     and         or   and     . These lines are shown on the image in figure 10.3. We see that these are indeed the “strongest” lines in the image in that they contain the greatest number of points. There is a problem with this implementation of the Hough transform, and that is that it can’t find vertical lines: we can’t express a vertical line in the form   , as  represents the gradient, and a vertical line has infinite gradient. We need another parameterization of lines. Consider a general line, as shown in figure 10.4. Clearly any line can be described in terms of the two parameters and : is the perpendicular di 10.1. THE HOUGH TRANSFORM 171   Image Figure 10.3: Lines found by the Hough transform  Figure 10.4: A line and its paramet 172 CHAPTER 10. THE HOUGH AND DISTANCE TRANSFORMS angle of the line’s perpendicular to the -axis. In this parameterization, vertical lines are simply those which have . If we allow to have negative values, we can restrict to the range     Given this parameterization, we need to be able to find the equation of the line. First note that the point   where the perpendicular to the line meets the line is        . Also note that the gradient of the perpendicular is    . Now let     be any point on then line. The gradient of the line is rise run            But since the gradient of the line’s perpendicular is  , the gradient of the line itself must be        Putting these two expressions for the gradient together produces:           If we now multiply out these fractions we obtain:          and this equation can be rewritten as   &          We finally have the required equation for the line as:      The Hough transform can then be implemented as follows: we start by choosing a discrete set of values of and to use. For each pixel    in the image, we compute     for each value of , and place the result in the appropriate position in the   array. At the end, the values of   with the highest values in the array will correspond to strongest lines in the image. An example will clarify this: consider the image shown in figure 10.5. We shall discretize to use 10.1. THE HOUGH TRANSFORM 173 0 1 2 3 4 0 1 2 3 4   Figure 10.5: A small image We can start by making a table containing all values &   for each point, and for each value of :                                                                 The accumulator array contains the number of times each value of   appears in the above table:                                  In practice this array will be very large, and can be displayed as an image. We see that the two equal largest values occur at     and      . The lines then are     or  , and   174 CHAPTER 10. THE HOUGH AND DISTANCE TRANSFORMS 0 1 2 3 4 0 1 2 3 4   Figure 10.6: Lines found by the Hough transform 10.2 Implementing the Hough transform in Matlab The Image Processing Toolbox does not contain a hough routine, and although the Hough transform can be obtained by other means, it is a pleasant programming exercise to write our own. Following the procedure outlined above, we will: 1. decide on a discrete set of values of and to use, 2. for each foreground pixel    in the image calculate the values of &   for all of our chosen values of , 3. create an accumulator array whose sizes are the numbers of angles and values in our chosen discretizations from step 1, 4. step through all of our values updating the accumulator array as we go. We shall consider each step in turn: Discretizing and . We observe that even though a particular pair   corresponds to only one line, a given line can be parameterized in different ways. For example, the line     can be parameterized using # and  as shown in figure 10.7(a). However, the same line can be parameterized using  and   . So we have a choice: we may restrict the values of , say to the range      , and let have both positive and negative values, or we may let take any value chosen from the range   # and restrict to non-negative values. Since we are going to use the values of and as indices into the accumulator array, it is simplest to take the second option. However, consider figure 10.7(a) slightly redrawn to take into account the directions of  and  as column and row indices of a matrix, as shown in (b). Since our image, for which both  and  will be positive, will sit in the bottom right quadrant, we will only have positive values for     . For if is outside that range, the perpendicular will point into the second (upper left) quadrant, which would require a negative value of if the line was to intersect the image. We can choose any discrete set of values we like, but let us take all the integer degree values in the given range, but convert them to radians for the 10.2.

Suppose that the image is binary, then we can find the positions of all the foreground pixels with a simple application of the find function: >> [x,y]=find(im); If the image is not binary, we can create a binary edge image by use of the edge function. Now we can calculate all the values with one simple command: >> r=floor(x*cos(angles)+y*sin(angles)); where we use floor so as to obtain only integer values. Forming the accumulator array. If the image is of size   pixels, then supposing the origin to be at the upper left corner, the maximum value of will be   . So the size of the accumulator array can be set at     . However, we are only interested in positive values of : given our choice of range of , negative values can be discarded. So we can first find the largest positive value of , and use that as one dimension of the array: >> rmax=max(r(find(r>0))); >> acc=zeros(rmax+1,270); The rmax+1 allows us to have values of . Updating the accumulator array. We now have to step through the array of values, and for each value   , increase the corresponding accumulator value by one. First notic 176 CHAPTER 10. THE HOUGH AND DISTANCE TRANSFORMS r, as define above, has size    , where  is the number of foreground pixels. Hence the second index of both r and acc corresponds to the angle. This can be done with nested loops, at the heart of which will be the command if r(i,j)>=0, acc(r(i,j)+1,i)=acc(r(i,j)+1,i)+1; Note that this is not a very efficient method of creating the accumulator array, but it does have the advantage of following the theory very closely. The entire program is shown in figure 10.8. function res=hough(image) % % HOUGH(IMAGE) creates the Hough transform corresponding to the image IMAGE % if ~isbw(image) edges=edge(image,’canny’); else edges=image; end; [x,y]=find(edges); angles=[-90:180]*pi/180; r=floor(x*cos(angles)+y*sin(angles)); rmax=max(r(find(r>0))); acc=zeros(rmax+1,270); for i=1:length(x), for j=1:270, if r(i,j)>=0 acc(r(i,j)+1,j)=acc(r(i,j)+1,j)+1; end; end; end; res=acc; Figure 10.8: A simple Matlab function for implementing the Hough transform An example Let us take the cameraman image, and apply our Hough transform procedure to it: >> c=imread(’cameraman.tif’); >> hc=hough(c); This last command may take some time, because of the inefficient nested loops. The first thing we may do is to view the result: >> imshow(mat2gray(hc)*1.5) where the extra 1.5 at the end is just to brighten up the image. The result is shown in figure 10.9. What we are viewing here is the accumulator array. And it is what we should expect: a series of curves, with some bright points indicating places of maximum intersection. Because of the use o 10.2. IMPLEMENTING THE HOUGH TRANSFORM IN MATLAB 177 Figure 10.9: The result of a Hough transform sines and cosines in the construction of the transform, we can expect the curves to be of a sinusoidal nature. What now? Let us find the maximum value of the transform: >> max(hc(:)) ans = 91 We can now find the and values corresponding to the maximum: >> [r,theta]=find(hc==91) r = 138 theta = 181 However, since we are using the pixel coordinates as cartesian coordinates, our  and  axes have been rotated counter-clockwise by . Thus we are measuring in a clockwise direction from the left vertical edge of our image. Figure 10.10 shows how this works: We have also got the problem that We can easily create a small function to draw lines for us, given their perpendicular distance from the origin, and the angle of the perpendicular from the  axis. The tool for this will be the line function, which in the form >> line([x1,x2],[y1,y 178 CHAPTER 10. THE HOUGH AND DISTANCE TRANSFORMS     Figure 10.10: A line from the Hough transform draws a line between coordinates     and     over the current image. The only difficulty here is that line takes the  axis to be on the top, and the  axis going down on the left. This is easily dealt with by replacing with   , and a simple function for drawing lines is shown in figure 10.11. The only thing to notice is the expression 181-theta in the line angle=pi*(181-theta)/180; This can be interpreted as    ; the initial  swaps between cartesian and matrix coordinates, and the extra 1 counters the accumulation of r+1 in the function hough.m. We can use this as follows: >> c2=imadd(imdivide(cm,4),192); >> imshow(c2) >> houghline(c2,r,theta) The idea of using c2 is simply to lighten the image so as to show the line more clearly. The result is shown on the left in figure 10.12. To draw other lines, we can extract some more points from the transform: >> [r,theta]=find(hc>80) r = 14 10.2.

Clearly we can use these functions to find any lines we like. 10.3 The distance transform In many applications, it is necessary to find the distance of every pixel from a region  . This can be done using the standard Euclidean distance:                   This means that to calculate the distance of    to  , we find all possible distances from    to pixels in  , and take the smallest value as our distance. This is very computationally inefficient: if  is large, then we have to compute many square roots. A saving can be obtained by noting that since the square root function is increasing, we can write the above definition as                  which involves only one square root. But even this definition is slow to compute. There is a great deal of arithmetic involved, and the finding of a smallest value. The distance transform is a computationally efficient method of finding such distance. We shall describe it in a sequence of steps: Step 1. Attach to each pixel    in the image a label      giving its distance from  . Start with labelling each pixel in  with 0, and each pixel not in  with . Step 2. We now travel through the image pixel by pixel. For each pixel     replace its label with                                    using   . Step 3. Repeat step 2 until all labels have been converted to finite 10.3. THE DISTANCE TRANSFORM 181 To give some examples of step 2, suppose we have this neighbourhood:         We are only interested in the centre pixel (whose label we are about to change), and the four pixels above, below, and to the left and right. To these four pixels we add 1:     The minimum of these five values is 3, and so that is the new label for the centre pixel. Suppose we have this neighbourhood:         Again, we add 1 to each of the four pixels above, below, to the left and right, and keep the centre value:      The minimum of these values is , and so at this stage the pixel’s label is not changed. Suppose we take an image whose labels after step 1 are given below                                                                                Step 1 Step 2 (first pass) Step 2 (second pass)                                      Step 2 (third pass) Step 2 (final pass) At this stage we stop, as all label values are finite. An immediate observation is that the distance values given are not in fact a very good approximation to “real” distances. To provide better accuracy, we need to generalize the above transform. One way to do this is to 182 CHAPTER 10. THE HOUGH AND DISTANCE TRANSFORMS Step two in the transform then consists of adding the corresponding mask elements to labels of the neighbouring pixels, and taking the minimum. To obtain good accuracy with simple arithmetic, the mask will generally consist of integer values, but the final result may require scaling. Suppose we apply the mask     to the above image. Step 1 is as above; steps 2 are:                                                                         Step 2 (first pass) Step 2 (second) Step 2 (third) at which point we stop, and divide all values by three:                                          These values are much closer to the Euclidean distances than those provided by the first transform. Even better accuracy can be obtained by using the mask                         and dividing the final result by 5:                                                                      Result of transform After division by 5 The method we have described can in fact be very slow; for a large image we may require many passes before all distance labels become finite. A quicker method requires two passes only: the first pass starts at the top left of the image, and moves left to right, and top to bottom. The second pass starts at the bottom right of the image, and moves right to left, and from bottom to top. For this method we break the mask 10.3. THE DISTANCE TRANSFORM 183 1 1 0 1 0 1 Mask 1 Forward mask Backward mask 3 4 3 4 0 3 3 4 4 0 Mask 2 Forward mask Backward mask 11 11 11 7 7 11 5 5 0 0 5 5 11 11 11 11 7 7 Mask 3 Forward mask Backward mask Figure 10.13: Pairs of masks for the two pass distance transform 184 CHAPTER 10. THE HOUGH AND DISTANCE TRANSFORMS (this is used for the first pass), and the other half inspects only values to the right and below (this is used for the second pass). Such pairs of masks are shown in figure 10.13, and the solid lines show how the original mask is broken up into its two halves. We apply these masks as follows: first surround the image with zeros (such as for spatial filtering), so that at the edges of the image the masks have values to work with. For the forward pass, for each pixel at position    , add the values given in the forward mask to its neighbours and take the minimum, and replace the current label with this minimum. This is similar to step 2 in the original algorithm, except that we are using less pixels. We do the same for the backward pass, except that we use the backwards mask, and we start at the bottom right. If we apply forward masks 1 and 2 to our image, the results of the forward passes are:                                                 Use of mask 1 Use of mask 2 After applying the backward masks, we will obtain the distance transforms as above. Implementation in Matlab We can easily write a function to perform the distance transform using the second method as above. Our function will implement the transform as follows: 1. Using the size of the mask, pad the image with an appropriate number of zeros. 2. Change each zero to infinity, and each one to zero. 3. Create forward and backwards masks. 4. Perform a forward pass: replace each label with the minimum of its neighbourhood plus the forward mask. 5. Perform a backwards pass: replace each label with the minimum of its neighbourhood plus the backwards mask. Let’s consider each of these steps separately: 1. Suppose the image is of size  , and the mask is of size  , where both mask dimensions are odd numbers. We need to add, on each side of the image, a number of columns equal to     , and we need to add, on both top and bottom of the image, a number of rows equal to     . In other words we can embed the image in a larger array of size          : >> [r,c]=size(image); >> [mr,mc]=size(mask); >> nr=(mr-1)/2; >> nc=(mc-1)/2; >> image2=zeros(r+mr-1,c+mc-1); >> image2 10.3. THE DISTANCE TRANSFORM 185 2. This can be easily done using the find function: first change all zeros to infinity, and next change all ones to zeros: >> image2(find(image2)==0)=Inf; >> image2(find(image2)==1)=0; 3. Suppose we are given a forward mask. We can do this most simply by making all blank entries in the masks shown in figure 10.13 infinity; this means that pixels in these positions will have no effect on the final minimum. The backwards mask can be obtained by two rotations. For example: >> mask1=[Inf 1 Inf;1 0 Inf;Inf Inf Inf]; >> backmask=rot90(rot90(mask1)); 4. We can implement the forward mask with nested loops: >> for i=nr+1:r+nr, for j=nc+1:c+nc, image2(i,j)=min(min(image2(i-nr:i+nr,j-nc:j+nc)+mask)); end; end; 5. The backward pass is done similarly: >> for i=r+nr:-1:nr+1, for j=c+nc:-1:nc+1, image2(i,j)=min(min(image2(i-nr:i+nr,j-nc:j+nc)+backmask)); end; end; The full function is shown in figure 10.14. Let’s try it out, first creating our image, and the three masks: >> im=[0 0 0 0 0 0;... 0 0 1 1 0 0;... 0 0 0 1 0 0;... 0 0 0 1 0 0;... 0 0 0 1 1 0;... 0 0 0 0 0 0] im = 0 0 0 0 0 0 0 0 1 1 0 0 0 0 0 1 0 0 0 0 0 1 0 0 0 0 0 1 1 0 0 0 0 0 186 CHAPTER 10.

We can of course apply the distance transform to a large image; say circles.tif: >> c=~imread(’circles.tif’); >> imshow(c) >> cd=disttrans(c,mask1); >> figure,imshow(mat2gray(cd)) Note that we invert the circles image to produce black circles on a white background. This means that our transform will find distances towards the inside of the original circles. The only reason for doing this is that it is easier to make sense of the resulting image. The circles image is shown on the leftt in figure 10.15 and the distance transform on the right. Figure 10.15: An example of a distance transform 10.3. THE DISTANCE TRANSFORM 189 Application to skeletonization The distance transform can be used to provide the skeleton of a region  . We apply the distance transform, using mask 1, to the image negative, just as we did for the circle above. Then the skeleton consist of those pixels    for which                              For example, suppose we take a small region concisting of a single rectangle, and find the distance transform of its negative: >> c=zeros(7,9);c(2:6,2:8)=1 c = 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 0 0 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 >> cd=disttrans(~c,mask1) cd = 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 1 1 0 0 1 2 2 2 2 2 1 0 0 1 2 3 3 3 2 1 0 0 1 2 2 2 2 2 1 0 0 1 1 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 We can obtain the skeleton using a double loop: >> skel=zeros(size(c)); >> for i=2:6, for j=2:8, if cd(i,j)>=max([cd(i-1,j),cd(i+1,j),cd(i,j-1),cd(i,j+1)]) skel(i,j)=1; end; end; end; >> skel skel 190 CHAPTER 10.

This can be used to find the largest value in a neighbourhood, and the neighbourhood can be very precisely defined: >> cd2=ordfilt2(cd,5,[0 1 0;1 1 1;0 1 0]) cd2 = 0 1 1 1 1 1 1 1 0 1 1 2 2 2 2 2 1 1 1 2 2 3 3 3 2 2 1 1 2 3 3 3 3 3 2 1 1 2 2 3 3 3 2 2 1 1 1 2 2 2 2 2 1 1 0 1 1 1 1 1 1 1 0 >> cd2<=cd ans = 1 0 0 0 0 0 0 0 1 0 1 0 0 0 0 0 1 0 0 0 1 0 0 0 1 0 0 0 0 0 1 1 1 0 0 0 0 0 1 0 0 0 1 0 0 0 1 0 0 0 0 0 1 0 1 0 0 0 0 0 0 0 1 We can easily restrict the image so as not to obtain the extra 1’s in the corners of the result. Now let’s do the same thing with our circles image: >> c=~imread(’circles.tif’); >> cd=disttrans(c,mask1); >> cd2=ordfilt2(cd,5,[0 1 0;1 1 1;0 1 0]); >> imshow((cd2<=cd)&~c) and the result is shown in figure 10.16. The use of the command (cd2<=cd)&~c blocks out the outside of the circles, so that just the skeleton is left. We will see in chapter 11 how to thicken this skeleton, and also other ways of obtaining the skeleton. 10.3.

THE HOUGH AND DISTANCE TRANSFORMS Chapter 11 Morphology 11.1 Introduction Morphology, or mathematical morphology is a branch of image processing which is particularly useful for analysing shapes in images. Although morphology can be applied to grey-scale images, we shall only investigate binary morphology. Matlab has many tools for binary morphology in the image processing toolbox; most of which can be used for greyscale morphology as well. 11.2 Basic ideas Translation Suppose that is a set of pixels in a binary image, and     is a particular coordinate point. Then  is the set “translated” in direction    . That is             For example, in figure 11.1, is the cross shaped set, and   . The set has been shifted 5 4 3 2 1 0 0 1 2 3 4 5 4 3 2 1 0 0 1 2 3 4  Figure 11.1: Translation in the  and  directions by the values given in . Note that here we are using matrix coordinates, rather than Cartesian coordinates, so that the origin is at the top left,  goes down and 196 CHAPTER 11. MORPHOLOGY Reflection If is set of pixels, then its reflection, denoted , is obtained by reflecting in the origin:              For examples, in figure 11.2, the open and closed circles form sets which are reflections of each other.      0 1 2 3 3 2 1 0     Figure 11.2: Reflection 11.3 Dilation and erosion These are the basic operations of morphology, in the sense that all other operations are built from a combination of these two. 11.3.1 Dilation Suppose and ! are sets of pixels. Then the dilation of by !, denoted  !, is defined as  !     What this means is that for every point   !, we translate by those coordinates. Then we take the union of all these translations. An equivalent definition is that  !               !  From this last definition, we see that dilation is commutative; that  ! !   An example of a dilation is given in figure 11.3. In the translation diagrams, the grey squares show the original position of the object. Note that   is of course just itself. In this example, we have !                        and those these are the coor 11.3.

Figure 11.3 198 CHAPTER 11. MORPHOLOGY In general,  ! can be obtained by replacing every point    in with a copy of !, placing the   point of ! at     . Equivalently, we can replace every point   of ! with a copy of . As you see in figure 11.3, dilation has the effect of increasing the size of an object. However, it is not necessarily true that the original object will lie within its dilation  !. Depending on the coordinates of !,  ! may end up quite a long way from . Figure 11.4 gives an example of this: is the same as in figure 11.3; ! has the same shape but a different position. In this figure, we have !                so that  !        8 7 6 5 4 3 2 1 1 2 3 4 ! 14 13 12 10 9 8 7 6 5 4 3 2 1 1 2 3 4 5 6 7 8  ! Figure 11.4: A dilation for which    For dilation, we generally assume that is the image being processed, and ! is a small set of pixels. In this case ! is referred to as a structuring element or as a kernel. Dilation in Matlab is performed with the command >> imdilate(image,kernel) To see an example of dilation, consider the commands: >> t= 11.3. DILATION AND EROSION 199 >> td=imdilate(t,sq); >> subplot(1,2,1),imshow(t) >> subplot(1,2,2),imshow(td) The result is shown in figure 11.5. Notice how the image has been “thickened”. This is really what dilation does; hence its name. Figure 11.5: Dilation of a binary image 11.3.2 Erosion Given sets and !, the erosion of by !, written  !, is defined as: !  !  In other words the erosion of by ! consists of all points     for which ! is in . To perform an erosion, we can move ! over , and find all the places it will fit, and for each such place mark down the corresponding   point of !. The set of all such points will form the erosion. An example of erosion is given in figures 11.6. Note that in the example, the erosion  ! was a subset of . This is not necessarily the case; it depends on the position of the origin in !. If ! contains the origin (as it did in figure 11.6), then the erosion will be a subset of the original object. Figure 11.7 shows an example where ! does not contain the origin. In this figure, the open circles in the right hand figure form the erosion. Note that in figure 11.7, the shape of the erosion is the same as that in figure 11.6; however its position is different. Since the origin of ! in figure 11.7 is translated by      from its position in figure 11.6, we can assume that the erosion will be translated by the same amount. And if we compare figures 11.6 and 11.7, we can see that the second erosion has indeed been shifted by      from the first. For erosion, as for dilation, we generally assume that is the image being processed, and ! is a small set of pixels: the structuring element or kernel. Erosion in Matlab is performed with the command >> i 200 CHAPTER 11.

Notice how the image has been “thinned”. This is the expected result of an erosion; hence its name. If we kept on eroding the image, we would end up with a completely black result. Figure 11.8: Erosion of a binary ima 202 CHAPTER 11. MORPHOLOGY 11.3.3 Relationship between erosion and dilation It can be shown that erosion and dilation are “inverses” of each other; more precisely, the complement of an erosion is equal to the dilation of the complement. Thus: !  !  To show this, see the proof in the box below. First note that, by its definition:       We also know that from elementary properties of subsets, that if   , then   . Thus:       (11.1) But the complement of     is clearly the set     Recall from the definition of dilation that         ! #"  !" $ % So if & "   , then & '() for some *"  and !" . Then &$+, -.

Then     6 as required. It can be similarly shown that the same relationship holds if erosion and dilation are interchanged; that  ! !  We can demonstrate the truth of these using Matlab commands; all we need to know is that the complement of a binary image b is obtained using >> ~b and that given two images a and b; their equality is determined with >> all(a(:)==b(:)) To demonstrate the equality !  !  pick a binary image, say the text image, and a structuring element. Then the left hand side of this equation is produced with >> lhs=~imerode(t,sq); and the ri 11.4. OPENING AND CLOSING 203 >> rhs=imdilate(~t,sq); Finally, the command >> all(lhs(:)==rhs(:)) should return 1, for true. 11.3.4 An application: boundary detection If is an image, and ! a small structuring element consisting of point symmetrically places about the origin, then we can define the boundary of by any of the following methods: (i)  +! “ internal boundary” (ii)   !  “external boundary” (iii)   !   ! “morphological gradient” In each definition the minus refers to set difference. For some examples, see figure 11.9. We see that the internal boundary consists of those pixels in which are at its edge; the external boundary consists of pixels outside which are just next to it, and that the morphological gradient is a combination of both the internal and external boundaries. To see some examples, choose the image rice.tif, and threshold it to obtain a binary image: >> rice=imread(’rice.tif’); >> r=rice>110; Then the internal boundary is obtained with: >> re=imerode(r,sq); >> r_int=r&~re; >> subplot(1,2,1),imshow(r) >> subplot(1,2,2),imshow(r_int) The result is shown in figure 11.10. The external boundary and morphological gradients can be obtained similarly: >> rd=imdilate(r,sq); >> r_ext=rd&~r; >> r_grad=rd&~re; >> subplot(1,2,1),imshow(r_ext) >> subplot(1,2,2),imshow(r_grad) The results are shown in figure 11.11. Note that the external boundaries are larger than the internal boundaries. This is because the internal boundaries show the outer edge of the image components; whereas the external boundaries show the pixels just outside the components. The morphological gradient is thicker than either, and is in fact the union of both. 11.4 Opening and closing These operations may be considered as “second level” operations; in that they build on the basic operations of dilation and erosion. They are also, as we shall see, better behaved mat 204 CHAPTER 11.

MORPHOLOGY 11.4.1 Opening Given and a structuring element !, the opening of by !, denoted  !, is defined as:  !  !  !  So an opening consists of an erosion followed by a dilation. An equivalent definition is  ! ! !  That is, ! is the union of all translations of ! which fit inside . Note the difference with erosion: the erosion consists only of the   point of ! for those translations which fit inside ; the opening consists of all of !. An example of opening is given in figure 11.12. 5 4 3 2 1 0 0 1 2 3 4 5 5 4 3 2 1 0 0 1 2 3 4 5 ! 5 4 3 2 1 0 0 1 2 3 4 5 ! Figure 11.12: Opening The opening operation satisfies the following properties: 1.  ! . Note that this is not the case with erosion; as we have seen, an erosion may not necessarily be a subset. 2.  ! !  !. That is, an opening can never be done more than once. This property is called idempotence. Again, this is not the case with erosion; you can keep on applying a sequence of erosions to an image until nothing is left. 3. If ", then  ! " ! . 4. Opening tends to “smooth” an image, to break narrow joins, and to remove thin protrusions. 11.4.2 Closing Analogous to opening we can define closing, which may be considered as a dilation followed by an erosion, and is denoted !: !   ! !  Another definition of closing is that   ! if all translations ! which contain  have non-empty intersections with . An example of closing is given in figure 11.13. The closing operation 11.4.

If ", then  ! " ! . 4. Closing tends also to smooth an image, but it fuses narrow breaks and thin gulfs, and eliminates small holes. Opening and closing are implemented by the imopen and imclose functions respectively. We can see the effects on a simple image using the square and cross structuring elements. >> cr=[0 1 0;1 1 1;0 1 0]; >> >> test=zeros(10,10);test(2:6,2:4)=1;test(3:5,6:9)=1;test(8:9,4:8)=1;test(4,5)=1 test = 0 0 0 0 0 0 0 0 0 0 0 1 1 1 0 0 0 0 0 0 0 1 1 1 0 1 1 1 1 0 0 1 1 1 1 1 1 1 1 0 0 1 1 1 0 1 1 1 1 0 0 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 1 1 1 1 1 0 0 0 0 0 1 1 1 1 1 0 0 0 0 0 0 0 0 0 0 0 0 >> imopen(test,sq) ans = 0 0 0 0 0 0 0 0 0 0 0 1 1 1 0 0 0 0 0 0 0 1 1 1 0 1 1 1 1 0 0 1 1 208 CHAPTER 11.

Figure 11.14: An example of closing An application: noise removal Suppose is a binary image corrupted by impulse noise—some of the black pixels are white, and some of the white pixels are back. An example is given in figure 11.15. Then ! will remove the single black pixels, but will enlarge the holes. We can fill the holes by dilating twice:   !  !  210 CHAPTER 11. MORPHOLOGY The first dilation returns the holes to their original size; the second dilation removes them. But this will enlarge the objects in the image. To reduce them to their correct size, perform a final erosion:    +!  !  ! +!  We see that the inner two operations constitute an opening; the outer two operations a closing. Thus this noise removal method is in fact an opening followed by a closing:  ! !  This is called morphological filtering. Suppose we take an image and apply   shot noise to it: >> c=imread(’circles.tif’); >> x=rand(size(c)); >> d1=find(x<=0.05); >> d2=find(x>=0.95); >> c(d1)=0; >> c(d2)=1; >> imshow(c) The result is shown as figure 11.15(a). The filterWe have discussed the Fourier transform and its uses in chapter 9. However, asing process can be implemented with >> cf1=imclose(imopen(c,sq),sq); >> figure,imshow(cf1) >> cf2=imclose(imopen(c,cr),cr); >> figure,imshow(cf2) and the results are shown as figures 11.15(b) and (c). The results are rather “blocky”; although less so with the cross structuring element. (a) (b) (c) Figure 11.15: A noisy binary image and the result after morphological fi 11.5. THE HIT-OR-MISS TRANSFORM 211 11.4.3 Relationship between opening and closing Opening and closing share a relationship very similar to that of erosion and dilation: the complement of an opening is equal to the closing of a complement, and complement of an closing is equal to the opening of a complement. Specifically: ! ! and  ! !  These can be demonstrated using similar techniques to those in section 11.3.3. 11.5 The hit-or-miss transform This is a powerful method for finding shapes in images. As with all other morphological algorithms, it can be defined entirely in terms of dilation and erosion; in this case, erosion only. Suppose we wish to locate    square shapes, such as is in the centre of the image in figure 11.16. We have discussed the Fourier transform and its uses in chapter 9. However, as Figure 11.16: An image  containing a shape to be found If we performed an erosion ! with ! being the square structuring element, we would obtain the result given in figure 11.17. Figure 11.17: The erosion  The result contains two pixels, as there are exactly two places in where ! will fit. Now suppose we also erode the complement of with a structuring element " which fits exactly around the    square; and " are shown in figure 11.18. (We assume that   is at the centre of ".) If we now perform the erosion " we would obtain the result shown in figure 11.19. The intersection of the two erosion operations would produce just one pixel at the position of the centre of the    square in , which is just what we want. If ha 212 CHAPTER 11. MORPHOLOGY : ": Figure 11.18: The complement and the second structuring element Figure 11.19: The erosion  square, the final result would have been single pixels at the positions of the centres of each. This combination of erosions forms the hit-or-miss transform. In general, if we are looking for a particular shape in an image, we design two structuring elements: ! which is the same shape, and !  which fits around the shape. We then write ! ! !  and  !  !   !   for the hit-or-miss transform. As an example, we shall attempt to find the hyphen in “Cross-Correlation” in the text image shown in figure 11.5. This is in fact a line of pixels of length six. We thus can create our two structuring elements as: >> b1=ones(1,6); >> b2=[1 1 1 1 1 1 1 1;1 0 0 0 0 0 0 1; 1 1 1 1 1 1 1 1]; >> tb1=erode(t,b1); >> tb2=erode(~t,b2); >> hit_or_miss=tb1&tb2; >> [x,y]=find(hit_or_miss==1) and this returns a coordinate of     , which is right in the middle of the hyphen. Note that the command >> tb1=erode(t,b1); is not sufficient, as there are quite a few lines of length six in this image. We can see this by viewing the image tb1, which is given in fig 11.6.

Figure 11.21: An -connected boundary of a region to be filled Given a pixel within the region, we wish to fill up the entire region. To do this, we start with , and dilate as many times as necessary with the cross-shaped structuring element ! (as used in figure 11.6), each time taking an intersection with before continuing. We thus create a sequen 214 CHAPTER 11. MORPHOLOGY of sets:         for which      !  Finally  is the filled region. Figure 11.22 shows how this is done. :        Figure 11.22: The process of filling a region In the right hand grid, we have           Note that the use of the cross-shaped structuring element means that we never cross the boundary. 11.6.2 Connected components We use a very similar algorithm to fill a connected component; we use the cross-shaped structuring element for -connected components, and the square structuring element for -connected components. Starting with a pixel , we fill up the rest of the component by creating a sequence of sets       such that      ! until    . Figure 11.23 shows an example. In each case we are starting in the centre of the square in the lower left. As this square is itself a -connected component, the cross structuring element cannot go beyond it. Both of these algorithms can be very easily implemented by Matlab functions. To implement region filling, we keep track of two images: current an 11.6.

The places where the lines of fire meet form the skeleton. The skeleton may be produced by morphological methods. Consider the table of operations as shown in table 11.1.

MORPHOLOGY Chapter 12 Colour processing For human beings, colour provides one of the most important descriptors of the world around us. The human visual system is particularly attuned to two things: edges, and colour. We have mentioned that the human visual system is not particularly good at recognizing subtle changes in grey values. In this section we shall investigate colour briefly, and then some methods of processing colour images 12.1 What is colour? Colour study consists of 1. the physical properties of light which give rise to colour, 2. the nature of the human eye and the ways in which it detects colour, 3. the nature of the human vision centre in the brain, and the ways in which messages from the eye are perceived as colour. Physical aspects of colour Visible light is part of the electromagnetic spectrum: radiation in which the energy takes the form of waves of varying wavelength. These range from cosmic rays of very short wavelength, to electric power, which has very long wavelength. Figure 12.1 illustrates this. The values for the wavelengths of blue, green and red were set in 1931 by the CIE (Commission Internationale d’Eclairage), an organization responsible for colour standards. Perceptual aspects of colour The human visual system tends to perceive colour as being made up of varying amounts of red, green and blue. That is, human vision is particularly sensitive to these colours; this is a function of the cone cells in the retina of the eye. These values are called the primary colours. If we add together any two primary colours we obtain the secondary colours: magenta (purple) red blue cyan green blue yellow red green  224 CHAPTER 12. COLOUR PROCESSING Cosmic rays Gamma rays X-rays UV light VISIBLE LIGHT Infra-red Microwaves TV Radio Electric Power                          Blue Green Red                    Figure 12.1: The electromagnetic spectrum and colours The amounts of red, green, and blue which make up a given colour can be determined by a colour matching experiment. In such an experiment, people are asked to match a given colour (a colour source) with different amounts of the additive primaries red, green and blue. Such an experiment was performed in 1931 by the CIE, and the results are shown in figure 12.2. Note that for some wavelengths, various of the red, green or blue values are negative. This is a physical impossibility, but it can be interpreted by adding the primary beam to the colour source, to maintain a colour match. To remove negative values from colour information, the CIE introduced the XYZ colour model. The values of , and  can be obtained from the corresponding  ,  and ! values by a linear transformation:                               !    The inverse transformation is easily obtained by inverting the matrix:    !                                     The XYZ colour matching functions corresponding to the  , , ! curves of figure 12.2 are shown in figure 12.3. The matrices given are not fixed; other matrices can be defined according to the definition of the colour white. Different definitions of 12.1.

Figure 12.4 shows a simple function which takes the relevant information out of this file and plots it. Figure 12.5 shows the similar function for plotting the RGB values (obtained from their XYZ counterparts by the linear transformation above). The CIE required that the component corresponded with luminance, or perceived brightness of the colour. That is why the row corresponding to in the first matrix (that is, the second row) sums to 1, and also why the curve in figure 12.3 is symmetric about the middle of the visible spectrum. In general, the values of , and  needed to form any particular colour are called the tristimulus values. Values corresponding to particular colours can be obtained from published tables. In order to discuss colour independent of brightness, the tristimulus values can be normalized by dividing by  :       1This file can be obtained from the Colour & Vision Research Laboratories web page h 226 CHAPTER 12.

Thus a colour can be specified by  and  alone, called the chromaticity coordinates. Given , , and , we can obtain the tristimulus values and  by working through the above equations backwards:           We can plot a chromaticity diagram, again using the ciexyz31.txt file of XYZ values: >> z=zeros(size(xyz)); >> xy=xyz./(sum(xyz’)’*[1 1 1]); >> x=xy(:,1)’; >> y=xy(:,2)’; >> figure,plot([x x(1)],[y y(1)]),axis square Here the matrix xyz consists of the second, third and fourth columns of the data, and plot is a function which draws a polygon with vertices taken from the x and y vectors. The extra x(1) and y(1) ensures that the polygon joins up. The result is shown in figure 12.6. The values of  and  which lie within the horseshoe shape in figure 12.6 represent values which correspond to physically realizable colours. 12.2 Colour models A colour model is a method for specifying colours in some standard way. It generally consists of a three dimensional coordinate system and a subspace of that system in which each colour is represented by a single point. We shall investigate three 228 CHAPTER 12.

This model is used for displays on computer screens; a monitor has three independent electron “guns” for the red, green and blue component of each colour. We may imagine all the colours sitting inside a “colour cube” of side  :  !    Black    Red    Green    Blue     Magenta     Yellow     Cyan   12.2. COLOUR MODELS 229 The colours along the black-white diagonal, shown in the diagram as a dotted line, are the points of the space where all the  , , ! values are equal. They are the different intensities of grey. RGB is the standard for the display of colours: on computer monitors; on TV sets. But it is not a very good way of describing colours. How, for example, would you define light brown using RGB? Note also from figure 12.2 that some colours require negative values of  ,  or !. These colours are not realizable on a computer monitor or TV set, on which only positive values are possible. The colours corresponding to positive values form the RGB gamut; in general a colour “gamut” consists of all the colours realizable with a particular colour model. We can plot the RGB gamut on a chromaticity diagram, using the xy coordinates obtained above. To define the gamut, we shall create a      array, and to each point    in the array, associate an XYZ triple defined by             . We can then compute the corresponding RGB triple, and if any of the RGB values are negative, make the output value white. This is easily done with the simple function shown in figure 12.7. function res=gamut() global cg; x2r=[3.063 -1.393 -0.476;-0.969 1.876 0.042;0.068 -0.229 1.069]; cg=zeros(100,100,3); for i=1:100, for j=1:100, cg(i,j,:)=x2r*[j/100 i/100 1-i/100-j/100]’; if min(cg(i,j,:))<0, cg(i,j,:)=[1 1 1]; end; end; end; res=cg; Figure 12.7: Computing the RGB gamut We can then display the gamut inside the chromaticity figure by >> imshow(cG),line([x’ x(1)],[y’ y(1)]),axis square,axis xy,axis on and the result is shown in figure 12.8. 12.2.2 HSV HSV stands for Hue, Saturation, Value. These terms have the following meanings: Hue: The “true colour” attribute (red, green, blue, orange, yellow, and so on). Saturation: The amount by which the colour as been diluted with white. The more white in the colour, the lower the saturation. So a deep red has high saturation, and a light red (a pinkish colour) has low saturation. Value: The degree of brightness: a well lit colour has high intensity; a dark colour has 230 CHAPTER 12.

We can visualize this model as a cone, as shown in figure 12.9. Any point on the surface represents a purely saturated colour. The saturation is thus given as the relative distance to the surface from the central axis of the structure. Hue is defined to be the angle measurement from a pre-determined axis, say red. 12.2.3 Conversion between RGB and HSV Suppose a colour is specified by its RGB values. If all the three values are equal, then the colour will be a grey scale; that is, an intensity of white. Such a colour, containing just white, will thus have a saturation of zero. Conversely, if the RGB values are very different, we would expect the resulting colour to have a high saturation. In particular, if one or two of the RGB values are zero, the saturation will be one, the highest possible value. Hue is defined as the fraction around the circle starting from red, which thus has a hue of zero. Reading around the circle in figure 12.9 produces the following hues: 12.2. COLOUR MODELS 231 Black 0 Saturation 1 0 1 Value Cyan Red Green Yellow Blue Magenta White Figure 12.9: The colour space HSV as a cone Colour Hue Red Yellow     Green      Cyan   Blue    Magenta     Suppose we are given three  , , ! values, which we suppose to be between 0 and 1. So if they are between 0 and 255, we first divide each value by 255. We then define:    !    ! To obtain a value for Hue, we consider several cases: 1. if  then      ! , 2. if  then   232 CHAPTER 12. COLOUR PROCESSING 3. if ! then        . If  ends up with a negative value, we add 1. In the particular case   !   , for which both , we define     . For example, suppose   !       We have                          Since !  we have              Conversion in this direction is implemented by the rgb2hsv function. This is of course designed to be used on    arrays, but let’s just experiment with our previous example: >> rgb2hsv([0.2 0.4 0.6]) ans = 0.5833 0.6667 0.6000 and these are indeed the , and values we have just calculated. To go the other way, we start by defining:                       Since  is a integer between 0 and 5, we have six cases to consider:    !    Let’s take the HSV values we computed above. We have:                     12.2. COLOUR MODELS 233 Since   we have   !          Conversion from HSV to RGB is implemented by the hsv2rgb function. 12.2.4 YIQ This colour space is used for TV/video in America and other countries where NTSC is the video standard (Australia uses PAL). In this scheme Y is the “luminance” (this corresponds roughly with intensity), and I and Q carry the colour information. The conversion between RGB is straightforward:                                   !   and    !                                   The two conversion matrices are of course inverses of each other. Note the difference between Y and I:            #!         ! This reflects the fact that the human visual system assigns more intensity to the green component of an image than to the red and blue components. Since YIQ is a linear transformation of RGB, we can picture YIQ to be a parallelepiped (a rectangular box which has been skewed in each direction) for which the Y axis lies along the central   to      line of RGB. Figure 12.10 shows this. Figure 12.10: The RGB cube and its YIQ transformation That the conversions are linear, and hence easy to do, makes this a good choice for colour image processing. Conversion between RGB 234 CHAPTER 12. COLOUR PROCESSING 12.3 Colour images in Matlab Since a colour image requires three separate items of information for each pixel, a (true) colour image of size   is represented in Matlab by an array of size   : a three dimensional array. We can think of such an array as a single entity consisting of three separate matrices aligned vertically. Figure 12.11 shows a diagram illustrating this idea. Suppose we read in an RGB image: Blue Green Red Figure 12.11: A three dimensional array for an RGB image >> x=imread(’lily.tif’); >> size(x) ans = 186 230 3 We can isolate each colour component by the colon operator: x(:,:,1) The first, or red component x(:,:,2) The second, or green component x(:,:,3) The third, or blue component These can all be viewed with imshow: >> imshow(x) >> figure,imshow(x(:,:,1)) >> figure,imshow(x(:,:,1)) >> figure,imshow(x(:,:,2)) These are all shown in figure 12.12. Notice how the colours with particular hues show up wi 12.3. COLOUR IMAGES IN MATLAB 235 A colour image Red component Green component Blue component Figure 12.12: An RGB colour image and its components high intensities in their respective components. For the rose in the top right, and the flower in the bottom left, both of which are predominantly red, the red component shows a very high intensity for these two flowers. The green and blue components show much lower intensities. Similarly the green leaves—at the top left and bottom right—show up with higher intensity in the green component than the other two. We can convert to YIQ or HSV and view the components again: >> xh=rgb2hsv(x); >> imshow(xh(:,:,1)) >> figure,imshow(xh(:,:,2)) >> figure,imshow(xh(:,:,3)) and these are shown in figure 12.13. We can do precisely the same thing for the YIQ colour space: Hue Saturation Value Figure 12.13: The HSV components >> xn=rgb2ntsc(x); >> imshow(xn(:,:,1)) >> figure,imshow(xn(:,:,2)) >> figure,imshow(xn(:,:,3)) and these are shown in figure 12.14. Notice that the Y component of YIQ gives a better greyscale version of the image than the value of HSV. The top right rose, in particular, is quite washed out in figure 12.13 (Value), but shows better contrast in figure 12.14 (Y). We shall see below how to put three matrices, obtained by operations on the separate components, back into a single three dimensional array for display. 236 CHAPTER 12. COLOUR PROCESSING Y I Q Figure 12.14: The YIQ components 12.4 Pseudocolouring This means assigning colours to a grey-scale image in order to make certain aspects of the image more amenable for visual interpretation—for example, for medical images. There are different methods of pseudocolouring. 12.4.1 Intensity slicing In this method, we break up the image into various grey level ranges. We simply assign a different colour to each range. For example: grey level: –   –    –    –   colour: blue magenta green red We can consider this as a mapping, as shown in figure 12.15. blue magenta green red colour         grey level Figure 12.15: Intensity slicing as a mapping 12.4.2 Grey—Colour transformations We have three functions     ,     ,     which assign red, green and blue values to each grey level . These values (with appropriate scaling, if necessary) are then used for display. Using an appropriate set of functions can enhance a grey-scale image with impress 12.4. PSEUDOCOLOURING 237    grey levels     The grey level  in the diagram is mapped onto red, green and blue values of   ,    and   respectively. In Matlab, a simple way to view an image with added colour is to use imshow with an extra colormap parameter. For example, consider the image blocks.tif. We can add a colourmap with the colormap function; there are several existing colourmaps to choose from. Figure 12.16 shows the children’s blocks image (from figure 1.4) after colour transformations. We created the colour (a) (b) Figure 12.16: Applying a colour map to a greyscale image image (a) with: >> b=imread(’blocks.tif’); >> imshow(b,colormap(jet(256)) However, a bad choice of colourmap can ruin an image. Image (b) in figure 12.16 is an example of this, where we apply the vga colourmap. Since this only has 16 rows, we need to reduce the number of greyscales in the image to 16. This is done with the grayslice function: >> b16=grayslice(b,16); >> figure,imshow(b16,colorm 238 CHAPTER 12. COLOUR PROCESSING The result, although undeniably colourful, is not really an improvement on the original image. The available colourmaps are listed in the help file for graph3d: v - Hue-saturation-value color map. t - Black-red-yellow-white color map. ay - Linear gray-scale color map. ne - Gray-scale with tinge of blue color map. pper - Linear copper-tone color map. nk - Pastel shades of pink color map. ite - All white color map. ag - Alternating red, white, blue, and black color map. nes - Color map with the line colors. lorcube - Enhanced color-cube color map. a - Windows colormap for 16 colors. t - Variant of HSV. ism - Prism color map. ol - Shades of cyan and magenta color map. tumn - Shades of red and yellow color map. ring - Shades of magenta and yellow color map. nter - Shades of blue and green color map. mmer - Shades of green and yellow color map. There are help files for each of these colourmaps, so that >> help hsv will provide some information on the hsv colourmap. We can easily create our own colourmap: it must by a matrix with 3 columns, and each row consists of RGB values between 0.0 and 1.0. Suppose we wish to create a blue, magenta, green, red colourmap as shown in figure 12.15. Using the RGB values: Colour Red Green blue Blue 0 0 1 Magenta 1 0 1 Green 0 1 0 Red 1 0 0 we can create our colourmap with: >> mycolourmap=[0 0 1;1 0 1;0 1 0;1 0 0]; Before we apply it to the blocks image, we need to scale the image down so that there are only the four greyscales 0, 1, 2 and 3: >> b4=grayslice(b,4); >> imshow(b4,mycolourmap) and the result is shown in figure 12.17. 12.5. PROCESSING OF COLOUR IMAGES 239 Figure 12.17: An image coloured with a “handmade” colourmap 12.5 Processing of colour images There are two methods we can use: 1. we can process each R, G, B matrix separately, 2. we can transform the colour space to one in which the intensity is separated from the colour, and process the intensity component only. Schemas for these are given in figures 12.18 and 12.19. We shall consider a number of different image processing tasks, and apply either of the above schema to colour images. Contrast enhancement This is best done by processing the intensity component. Suppose we start with the image cat.tif, which is an indexed colour image, and convert it to a truecolour (RGB) image. >> [x,map]=imread(’cat.tif’); >> c=ind2rgb(x,map); Now we have to convert from RGB to YIQ, so as to be able to isolate the intensity component: >> cn=rgb2ntsc(c); Now we apply histogram equalization to the intensity component, and convert back to RGB for display: >> cn(:,:,1)=histeq(cn(:,:,1)); >> c2=ntsc2rgb(cn); >> imshow(c2) The result is shown in figure 12.20. Whether this is an improvement is debatable, but it has had its contrast enhanced. But suppose we try to apply histogram equalization to each of the RGB components: 240 CHAPTER 12. COLOUR PROCESSING Image   !   ! Output Figure 12.18: RGB processing   Image         Output Figure 12.19: Intensity proces 12.5. PROCESSING OF COLOUR IMAGES 241 >> cr=histeq(c(:,:,1)); >> cg=histeq(c(:,:,2)); >> cb=histeq(c(:,:,3)); Now we have to put them all back into a single 3 dimensional array for use with imshow. The cat function is what we want: >> c3=cat(3,cr,cg,cb); >> imshow(c3) The first variable to cat is the dimension along which we want our arrays to be joined. The result is shown for comparison in figure 12.20. This is not acceptable, as some strange colours have been introduced; the cat’s fur has developed a sort of purplish tint, and the grass colour is somewhat washed out. Intensity processing Using each RGB component Figure 12.20: Histogram equalization of a colour image Spatial filtering It very much depends on the filter as to which schema we use. For a low pass filter, say a blurring filter, we can apply the filter to each RGB component: >> a15=fspecial(’average’,15); >> cr=filter2(a15,c(:,:,1)); >> cg=filter2(a15,c(:,:,2)); >> cb=filter2(a15,c(:,:,3)); >> blur=cat(3,cr,cg,cb); >> imshow(blur) and the result is shown in figure 12.21. We could also obtain a similar effect by applying the filter to the intensity component only. But for a high pass filter, for example an unsharp masking filter, we are better off working with the intensity component only: >> cn=rgb2ntsc(c); >> a=fspecial(’unsharp’); 242 CHAPTER 12. COLOUR PROCESSING >> cn(:,:,1)=filter2(a,cn(:,:,1)); >> cu=ntsc2rgb(cn); >> imshow(cu) and the result is shown in figure 12.21. In general, we will obtain reasonable results using the Low pass filtering High pass filtering Figure 12.21: Spatial filtering of a colour image intensity component only. Although we can sometimes apply a filter to each of the RGB components, as we did for the blurring example above, we cannot be guaranteed a good result. The problem is that any filter will change the values of the pixels, and this may introduce unwanted colours. Noise reduction As we did in chapter 7, we shall use the image twins.tif: but now in full colour! >> tw=imread(’twins.tif’); Now we can add noise, and look at the noisy image, and its RGB components: >> tn=imnoise(tw,’salt & pepper’); >> imshow(tn) >> figure,imshow(tn(:,:,1)) >> figure,imshow(tn(:,:,2)) >> figure,imshow(tn(:,:,3)) These are all shown in figure 12.22. It would appear that we should apply median filtering to each of the RGB components. This is easily done: >> trm=medfilt2(tn(:,:,1)); >> tgm=medfilt2(tn(:,:,2)); >> tbm=medfilt2(tn(:,:,3)); >> tm=cat(3,trm,tgm,tbm); >> imshow(tm) and the result is shown in figure 12.23. We can’t in this instance apply the median filter to the intensity component only, because the conversion from RGB to YIQ spreads the noise across all the YIQ components. If we remove the noise from Y only: 12.5. PROCESSING OF COLOUR IMAGES 243 Salt & pepper noise The red component The green component The blue component Figure 12.22: Noise on a colour image 244 CHAPTER 12. COLOUR PROCESSING >> tnn=rgb2ntsc(tn); >> tnn(:,:,1)=medfilt2(tnn(:,:,1)); >> tm2=ntsc2rgb(tnn); >> imshow(tm2) we see, as shown in figure 12.23 that the noise has been slightly diminished, but it is still there. Denoising each RGB component Denoising Y only Figure 12.23: Attempts at denoising a colour image Edge detection An edge image will be a binary image containing the edges of the input. We can go about obtaining an edge image in two ways: 1. we can take the intensity component only, and apply the edge function to it, 2. we can apply the edge function to each of the RGB components, and join the results. To implement the first method, we start with the rgb2gray function: >> fg=rgb2gray(f); >> fe1=edge(fg); >> imshow(fe1) Recall that edge with no parameters implements Sobel edge detection. The result is shown in figure 12.24. For the second method, we can join the results with the logical “or”: >> f1=edge(f(:,:,1)); >> f2=edge(f(:,:,2)); >> f3=edge(f(:,:,3)); >> fe2=f1 | f2 | f3; >> figure,imshow(fe2) 12.5. PROCESSING OF COLOUR IMAGES 245 fe1: Edges after rgb2gray fe2: Edges of each RGB component Figure 12.24: The edges of a colour image and this is also shown in figure 12.24. The edge image fe2 is a much more complete edge image. Notice that the rose now has most of its edges, where in image fe1 only a few were shown. Also note that there are the edges of some leaves in the bottom left of fe2 which are completely missing from fe1. Exercises 1. By hand, determine the saturation and intensity components of the following image, where the RGB values are as given:                                                                                           2. Suppose the intensity component of an HSI image was thresholded to just two values. How would this affect the appearance of the image? 3. By hand, perform the conversions between RGB and HSV or YIQ, for the values:   !                               !                     246 CHAPTER 12. COLOUR PROCESSING 4. Check your answers to the conversions in question 3 by using the Matlab functions rgb2hsv, hsv2rgb, rgb2ntsc and ntsc2rgb. 5. Threshold the intensity component of a colour image, say flowers.tif, and see if the result agrees with your guess from question 2 above. 6. The image spine.tif is an indexed colour image; however the colours are all very close to shades of grey. Experiment with using imshow on the index matrix of this image, with varying colourmaps of length 64. Which colourmap seems to give the best results? Which colourmap seems to give the worst results? 7. View the image autumn.tif. Experiment with histogram equalization on: (a) the intensity component of HSV, (b) the intensity component of YIQ. Which seems to produce the best result? 8. Create and view a random “patchwork quilt” with: >> r=uint8(floor(256*rand(16,16,3))); >> r=imresize(r,16); >> imshow(r),pixval on What RGB values produce (a) a light brown colour? (b) a dark brown colour? Convert these brown values to HSV, and plot the hues on a circle. 9. Using the flowers image, see if you can obtain an edge image from the intensity component alone, that is as close as possible to the image fe2 in figure 12.24. What parameters to the edge function did you use? How close to fe2 could you get? 10. Add Gaussian noise to an RGB colour image x with >> xn=imnoise(x,’gaussian’); View your image, and attempt to remove the noise with (a) average filtering on each RGB component, (b) Wiener filtering on each RGB component. Chapter 13 Image coding and compression We have seen that image files can be very large. It is thus important for reasons both of storage and file transfer to make these file sizes smaller, if possible. In section 1.8 we touched briefly on the topic of compression; in this section we investigate some standard compression methods. 13.1 Lossless compression This refers to the compression keeping all information, so that the image can be decompressed with no loss of information. This is preferred for images of legal or scientific significance, where loss of data—even of apparent insignificance, could have considerable consequences. Unfortunately this style tends not to lead to high compression ratios. However, lossless compression is used as part of many standard image formats. Huffman coding The idea of Huffman coding is simple. Rather than using a fixed length code (8 bits) to represent the grey values in an image, we use a variable length code, with smaller length codes corresponding to more probable grey values. A small example will make this clear. Suppose we have a 2-bit greyscale image with only four grey levels: 0, 1, 2, 3, with the probabilities 0.2, 0.4, 0.3 and 0.1 respectively. That is, 20% of pixels in the image have grey value 50; 40% have grey value 100, and so on. The following table shows fixed length and variable length codes for this image: Grey value Probability Fixed code Variable code 0 0.2 00 000 1 0.4 01 1 2 0.3 10 01 3 0.1 11 001 Now consider how this image has been compressed. Each grey value has its own unique identifying code. The average number of bits per pixel can be easily calculated as the expected value (in a probabilistic sense):                         Notice that the longest codewords are associated with the lowest probabilities. Although this average is only slightly smaller than 2, it is smaller by a significant amoun 248 CHAPTER 13. IMAGE CODING AND COMPRESSION To obtain the Huffman code for a given image we proceed as follows: 1. Determine the probabilities of each grey value in the image. 2. Form a binary tree by adding probabilities two at a time, always taking the two lowest available values. 3. Now assign 0 and 1 arbitrarily to each branch of the tree from its apex. 4. Read the codes from the top down. To see how this works, consider the example of a 3-bit greyscale image (so the grey values are 0–7) with the following probabilities: Grey value 0 1 2 3 4 5 6 7 Probability 0.19 0.25 0.21 0.16 0.08 0.06 0.03 0.02 We can now combine probabilities two at a time as shown in figure 13.1. 7 6 5 4 3 2 1 0 0.02 0.03 0.06 0.08 0.16 0.21 0.25 0.19 0.05 0.11 0.19 0.35 0.60 0.40 1 Figure 13.1: Forming the Huffman code tree Note that if we have a choice of probabilities we choose arbitrarily. The second stage consists of arbitrarily assigning 0’s and 1’s to each branch of the tree just obtained. This is shown in figure 13.2. To obtain the codes for each grey value, start at the 1 on the top right, and work back towards the grey value in question, listing the numbers passed on the way. This produces: Grey value Huffman code 0 00 1 10 2 01 3 110 4 1110 5 11110 6 111110 7 111111 13.1. LOSSLESS COMPRESSION 249 7 6 5 4 3 2 1 0 0.02 0.03 0.06 0.08 0.16 0.21 0.25 0.19 0.05 0.11 0.19 0.35 0.60 0.40 1 0 1 0 1 0 1 0 1 0 1 0 1 0 1 Figure 13.2: Assigning 0’s and 1’s to the branches As above, we can evaluate the average number of bits per pixel as an expected value:                                             which is a significant improvement over 3 bits per pixel. Huffman codes are uniquely decodable, in that a string can be decoded in only one way. For example, consider the string            to be decoded with the Huffman code generated above. There is no code word 1, or 11, so we may take the first three bits 110 as being the code for grey value 3. Notice also that no other code word begins with this string. For the next few bits, we find that 1110 is a code word; no other begins with this string, and no other smaller string is a codeword. So we can decode this string as grey level 4. Continuing in this way we find:                            as the decoding for this string. For more information about Huffman coding, and its limitations and generalizations, see [5, 17]. Run length encoding Run length encoding (RLE) is based on a simple idea: to encode strings of zeros and ones by the number of repetitions in each string. RLE has become a standard in facsimile transmission. For a binary image, there are many different implementations of RLE; one method is to encode each line separately, starting with the number of 250 CHAPTER 13. IMAGE CODING AND COMPRESSION 0 0 1 1 1 0 1 1 1 0 0 1 0 1 1 1 1 0 0 0 0 1 1 1 1 0 0 0 1 1 would be encoded as                       Another method [20] is to encode each row as a list of pairs of numbers; the first number in each pair given the starting position of a run of 1’s, and the second number its length. So the above binary image would have the encoding                     Greyscale images can be encoded by breaking them up into their bit planes; these were discussed in chapter 4. To give a simple example, consider the following 4-bit image and its binary representation:                                              We may break it into bit planes as shown:          0th plane          1st plane       2nd plane         3rd plane and then each plane can be encoded separately using our chosen implementation of RLE. However, there is a problem with bit planes, and that is that small changes of grey value may cause significant changes in bits. For example, the change from value 7 to 8 causes the change of all four bits, since we are changing the binary strings 0111 to 1000. The problem is of course exacerbated for 8-bit images. For RLE to be effective, we should hope that long runs of very similar grey values would result in very good compression rates for the code. But as we see, this may not be the case. A 4-bit image consisting of randomly distributed 7’s and 8’s would thus result in uncorrelated bit planes, and little effective compression. To overcome this difficulty, we may encode the grey values with their binary Gray codes. A Gray code is an orderi 13.1. LOSSLESS COMPRESSION 251 between a string and the next. So a 4-bit Gray code is:                                               See [17] for discussion and detail. To see the advantages, consider the following 4-bit image with its binary and Gray code encodings:                                                                    where the first binary array is the standard binary encoding, and the second array the Gray codes. The binary bit planes are:          0th plane          1st plane          2nd plane        3rd plane and the bit planes corresponding to the Gray codes are: 0th plane 1st plane                 2nd plane   252 CHAPTER 13.

necessaire a l'utilisation du logiciel Matlab. Les conventions suivantes sont adoptees:  le texte en caractere typeset decrit des codes Matlab,  un \;" a la n de la ligne indique a Matlab de ne pas acher la commande qu'il execute.  De nombreuses fonctions et instructions ne sont pas detaillees dans cette note, mais leurs codes sont donnes en annexe. 1 Manipulations de vecteurs et de matrices 1.1 Construire une Matrice Il y a plusieurs manieres pour construire une matrice avec Matlab.  La premiere, et peut ^etre la plus simple, est de declarer la matrice comme on l'ecrit a la main: A=[1 2 3 4 5 6] Ceci cree une matrice (2 3) matrix de la forme: 1 2 3 4 5 6 !  Une autre possibilite est d'ecrire: A=[1 2 3;4 5 6] Ces exemples montrent que dans les crochets, un espace sert a separer les colonnes, alors qu'un \;" sert a separer les lignes de la matrice. 1  Finalement, il est possible de declarer une matrice element par element: A(1,1)=1; A(1,2)=2; A(1,3)=3; A(2,1)=4; A(2,2)=5; A(2,3)=6; 1.2 Les matrices particulieres Il y a des matrices particulieres qu'il est tres utile de conna^tre:  La matrice zero: on cree une matrice (r c) de 0 en utilisant l'instruction zeros(r,c). Par exemple: A=zeros(2,3); cree la matrice: A = 0 0 0 0 0 0 !  La matrice de un: on peut creer une matrice (rc) de 1 en utilisant l'instruction ones(r,c). Par exemple: A=ones(2,3); cree la matrice: A = 1 1 1 1 1 1 !  la matrice identite In peut ^etre cree gr^ace a la commande eye(n), ou n est la dimension de la matrice. Ainsi, A=eye(3); cree la matrice: A = 0 B @ 1 0 0 0 1 0 0 0 1 1 C A  une matrice aleatoire: on peut creer une matrice (rc) d'elements aleatoires en utilisant la commande rand(r,c), pour des elements uniformement distribues, ou randn(r,c), pour des elements normalement distribues. Il doit ^etre note que rand tire des nombre sur le support [0;1] alors que randn tire des nombres dans la une loi normale N (0; 1). 2  La matrice vide peut ^etre utile lors de l'initialisation d'une matrice: A=[ ]; de nit A comme la matrice vide. 1.3 Manipulations de base Une des operations de base les plus courante consiste a extraire des elements d'une matrice. Matlab donne un ensemble d'instruments tres puissants pour e ectuer ces operations. Considerons la matrice: A = 0 B B B B B @ 1 2 3 4 5 2 3 4 5 1 3 4 5 1 2 4 5 1 2 3 5 1 2 3 4 1 C C C C C A  On veut isoler la matrice centrale: B = 0 B B B @ 2 3 3 4 4 5 5 1 1 C C C A Pour obtenir B, les commandes Matlab sont: B=A(1:4,2:3) 1:4 signi e la sequence 1 2 3 4 et 2:3 la sequence 2 3, de telle sorte que B=A(1:4,2:3) est l'instruction qui va permettre de de nir B comme une selection des ligne 1 2 3 4 de A et de colonnes 2 et 3.  Supposons que nous voulions selectionner les colonnes 1 et 3, mais que nous voulions garder toutes les lignes. L'instruction est alors: B=A(:,[1 3]); Le : signi e "selectionner tout", alors que [1 3] est juste un vecteur contenant les nombres 1 et 3. Ainsi, tous les elements des colonnes 1 et 3 sont selectionne.  Mais des operations plus complexes peuvent ^etre envisagees. Imaginons que l'on veuille selectionner les elements de la matrice A superieur ou egal a 3, a n de les stocker dans un vecteru B: 3 B=A(A>=3); Si A(i; j) >= 3 alors stocker dans le vecteur B.  Maintenant, considerons la matrice: A = 0 B @ 1 2 3 4 5 6 1 C A et supposons que nous voulions en obtenir la vectorialisation, alors il sut de donner l'instruction: B=A(:); pour obtenir: B = 0 B B B B B B B @ 1 3 5 2 4 6 1 C C C C C C C A  Si on veut obtenir la matrice A a partir de la matrice B, il sut d'utiliser la commande reshape: A=reshape(B,3,2) ce qui signi e que le vecteur B prendra la forme d'une matrice (3 2), comme la matrice A.  Si l'on veut agglomerer des matrices, il sut de suivre les instructions suivantes. Supposons que nous ayons les deux matrices suivantes: A = 1 2 3 4 ! et B = 4 5 6 7 8 9 ! et que l'on veuille la matrice suivante: C = 0 B B B @ 1 2 0 0 0 3 4 0 0 0 0 0 4 5 6 0 0 7 8 9 1 C C C A alors, il sut d'ecrire: 4 C=[A zeros(2,3);zeros(2,2) B];  Le tableau suivant resume les autres manipulations possibles: rot90(A) rotation de A diag(A) cree ou extrait la diagonale de A tril(A) partie triangulaire inf. de A triu(A) partie triangulaire sup. de A 1.4 Operations de base Le tableau suivant resume les operations matricielles disponibles sous Matlab: Action equivalent Math. Matlab Commentaire taille A est (r c) [r,c]=size(A) Transposition A0 A' Addition A + B A+B dim(A) = dim(B) Produit A B A*B Compatilite Produit element par element AijBij A.*B dim(A) = dim(B) Division 1 X solution de A X = B An B Compatilite Division 2 X solution de X A = B An B Compatilite Division element par element Aij=Bij A./B dim(A) = dim(B) Puissance d'une matrice An A^ n A carree Puissance element par element An ij A.^ n Trace tr(A) trace(A) A carree Determinant det(A) det(A) A carree Produit de Kronecker A B kron(A,B) Inverse A1 inv(A) A carree Rang rang(A) rank(A) Noyau (A V = 0) V=null(A) Valeur propre A = D P 1 [P,D]=eig(A) A carree Somme des colonnes Prows(A) i=1 Ai: sum(A) Produit des colonnes rows(A) i=1 Ai: prod(A) 2 Contr^oler la sequence des instructions Comme beaucoup d'autre langage, Matlab peut contr^oler la sequence des instructions d'un programme. Il y a trois facons de faire. 2.1 La boucle avec for Matlab peut repeter un ensemble d'instruction un nombre donne de fois, en utilisant l'instruction for. La forme generale de la boucle est alors: for variable=expression; instruction; end; En fait, expression est une matrice contenant des nombres. Exemple 1 : Generer la matrice A t.q.: Aij = i 2 j 3 + 1; pour i = 1; : : : ; 20 et j = 1; : : : ; 10 Les codes Matlab correspondant sont: for i=1:1:20; % i va de 1 a 20 avec un pas de 1 : for i=init:step:final for j=1:1:10; % j va de 1 a 10 avec un pas de 1 : for j=init:step:final A(i,j)=i^2-j^3+1; end; end; Exemple 2 : Calculer Ab ij , pour b allant de 0 a 1 avec un pas de 0.1, et acher le resultat a chaque iteration. Les codes sont: A=[1 2;2 1]; for b=0:0.1:1; % i va de 0 a 1 avec un pas de 0.1 C=A.^b; disp(C) % afficher C end; 2.2 La boucle avec while Matlab peut aussi utiliser des boucles pour repeter des instructions jusqu'a ce qu'une condition terminale soit satisfaite. La syntaxe generale des boucles avec while est la suivante: while condition; instructions; end; Tant que condition est satisfait, les instructions seront executees. Exemple 1 : trouver un point xe de la relation dynamique suivante (pas de solution analytique): xt+1 = 1 + x0:2 t Tout ce que l'on peut faire, c'est iterer sur cette relation et stopper quand la difference en valeur absolue entre deux iterations est inferieur a un seuil de tolerance. Les codes sont: tol=1e-6; % critere de tolerance crit=1; % initialisation du critere x0=1; % valeur initiale de x while crit>tol; x=1+x0^0.2; % relation dynamique crit=abs(x-x0); % valeur absolue entre 2 iterations consecutives x0=x; % la nouvelle valeur de x(t) end; 2.3 La boucle avec if L'instruction if execute un ensemble de commande si une condition est satisfaite. La syntaxe generale est: if condition commandes 1 else commandes 2 end Exemple 1 : savoir si un entier est impair ou non. Les codes sont alors les suivants: x=input('entrer un entier: '); % Demande a l'utilisateur d'entrer un entier % et le stock dans le vecteur x if rem(x,2)==0; % si le reste de la division par 2 est nul, alors disp('x est pair'); % afficher le message: x est pair else; % sinon disp('x est impair'); % afficher le message: x est impair end; % fin du test Ces commandes peuvent ^etre enrichies de la facon suivante: if condition commandes 1 elseif condition commandes 2 else commandes 3 end Exemple 2 : Construction d'une fonction de demande de la forme: D(P ) = 8 >< >: 0 si p  2 1 0:5P si 2 < p  3 2P 2 sinon Les codes sont les suivant: P=input('entrer un prix : '); if P<=2; D=0; elseif (P>2)&(P<=3); D=1-0.5 P; else; D=2*P^(-2); end; disp(D); Ces instructions peuvent evidement ^etre combinees les unes avec les autres. L'exemple 3 donne une illustration de la combinaison entre les instructions for et if, en utilisant l'instruction break qui permet de sortir d'une boucle avant la n de celle-ci. Exemple 3: Construire la sequence suivante: xt = x0:4 t1 x0:2 t1 pour t = 1; : : : ; 100. On doit s'assurer que x reste positif autrement Matlab trouvera une valeur complexe! Les codes suivant permettent de generer cette sequence et nous font sortir de la boucle des que le resultat d'une iteration est negatif: x(1)=2; for i=2:1:100; y=x(i-1)^0.4-x(i-1)^0.2; if y<0; disp('le resultat ne peut pas etre negatif'); break; end; x(i)=y; end; Avec cette ensemble de trois instructions, il est normalement possible de resoudre tous vos problemes numeriques a l'aide de Matlab. Toutefois, une autre capacite de Matlab est de vous permettre de construire des nouvelles fonctions. 3 De nition et utilisation des vos propres fonctions Les fonctions sont des sous-programmes annexes qu'il est possible d'appeler avec des codes usuels. La syntaxe generale pour de nir une fonction est: function [output]=nom_de_la_fonction(input); instructions; ou output designe le vecteur des resultats, et input designe le vecteur des parametres a entrer pour la resolution de la fonction. Cette fonction doit ^etre sauvee dans un chier texte ("script le") portant le m^eme nom que la fonction. Par exemple, construisons une fonction, appelee stat, qui nous donne la moyenne et l'ecart-type d'un vecteur. On doit alors creer, a l'aide de votre editeur favori, un chier nomme stat.m, contenant le texte suivant: function [m,st]=stat(x); lx=length(x); m=sum(x)/lx; st=sqrt(sum(x-mx)^2)/lx; Soit le vecteur: x=[1;2;3;4;5;6]; En appelant [mx,sx]=stat(x) dans un autre programme, vous obtiendrez mx=3.5000 et sx=1.8708. Les fonctions sont tres importantes pour le traitement de certain probleme. Un des plus important en economie est le calcul de l'etat stationnaire d'un modele. Celui-ci peut ^etre resolu en utilisant la routine fsolve qui resout les systemes nonlineaires. Par exemple, dans le cas du modele neo-classique de croissance, on doit resoudre le suivant suivant 1 : 1 = ( A k 1 + 1 ) k = A k c Il faut alors creer une fonction a deux variables, appelee par exemple steady, dans un chier appele steady.m: function z=steady(x); alpha=0.35; beta=0.99; delta=0.025; A=1; k=x(1); c=x(2); z=zeros(2,1); % Initialisation de z. % Pas necessaire, mais recommande z(1)=1-beta*(alpha*A*k^(alpha-1)+1-\delta); % Remarque: la fonction est z(2)=delta*k-(A*k^alpha-c); % ecrite f(x)=0 et, dans un autre chier, donner les conditions initiales a n de permettre la resolution numerique de ce systeme: k0=10; c0=1; x0=[k0;c0]; sol=fsolve('steady',x0); Un autre avantage des fonctions est qu'elles permettent de vous creer une librairie que vous pouvez utiliser quand vous en avez besoin pour diverses problemes. 1 Remarque: cet exemple peut ^etre resolu a la main, mais il a ete choisi pour sa simplicite. 4 Outils Input{Output Les instructions Input { Output sont importantes car elles permettent d'acher, de sauver et d'utiliser vos resultats dans d'autres codes que ceux utilises par Matlab. 4.1 Textes Input { Output La premiere commande est celle permettant d'acher une commande: disp. Elle vous permet d'acher un message, une valeur ou ce que vous voulez comme texte. Ainsi disp('Ceci est un beau message') achera \Ceci est un beau message" a l'ecran. Soit une matrice A de la forme: A = 1 2 3 4 ! alors: disp(A) achera a l'ecran: 1 2 3 4 Si vous desirez stocker vos resultats dans un chier, il faut ouvrir un chier et faire acher vos resultats sous la forme que vous voulez. Pour cela, utiliser la commande diary name of file. Ne pas oublier de fermer votre chier avec la commande diary off. Par exemple: diary result.out disp('Salut') diary off cree un chier appele result.out contenant \Salut". Attention: l'instruction diary n'ecrase pas le(s) chier(s) existant sous le m^eme nom. Il est donc necessaire, dans un premier temps, d'e acer le(s) vieu(x) chier(s) en utilisant delete name of file, si vous ne voulez pas a jouter de nouvelles informations dans le chier existant, mais seulement avoir un chier donnant les nouveaux resultats. Si on desire que l'utilisateur du programme entre une information avec le clavier, utiliser l'instruction input. n=input('Donner un nombre'); 10 ache le message \Donner un nombre" a l'ecran en attendant une reponse. La reponse est enregistree dans la variable n. Si on desire charger des donnees, vous avez simplement a creer un chier ASCII contenant ces donnees. Par exemple supposons que le chier de donnees dat.txt est de la forme: 1 2 3 4 5 6 Donner juste l'instruction: load dat.txt -ascii; et vos donnees sont stockees dans une matrice, appelee dat, que vous pouvez manipuler comme toutes les matrices. 4.2 Graphiques La premiere instruction importante est clg: elle permet d'e acer le graphique a l'ecran. Dans cette note d'introduction a Matlab, seuls les graphiques en 2-d seront abordes (se sont les plus commun)2 . Il y a essentiellement une instruction: plot. La syntaxe generale de plot est: plot(X,Y,S) ou X et Y sont des matrices et S est une cha^ne de caracteres 1, 2 ou 3 de nissant l'aspect du graphique. L'instruction ci-dessus dessine Y comme une fonction de X. La cha^ne S est une option et peut prendre les valeurs suivantes: y jaune . point m magenta o cercle c cyan x x-marque r rouge + plus g vert - trait plein b bleu * etoile w blanc : pointille k noir -. tirets-point { traits espaces Ainsi plot(X,Y,'b*') dessine une etoile bleue en chaque point de l'echantillon. Il est possible d'a jouter des titres, des legendes pour les axes, en utilisant les instructions suivantes: 2 Pour le graphiques en 3-d, voir le manuel "Matlab Graphics". 11 title(string) % xlabel(string) % titre de l'axe des x ylabel(string) % titre de l'axe des y Il est egalement possible de ra jouter une grille sur votre graphique, en utilisant l'instruction grid. Les graphiques, crees a partir des instructions suivantes sont reportes en annexe (A). Le graphique (1) est de ni par les codes suivants: x=[-3:.01:3]; y1=exp(-0.5*x.^2)/sqrt(2*pi); y2=exp(-0.25*x.^2)/sqrt(2*pi); clg; plot(x,y1,'w',x,y2,'w--'); title('Un bel exemple ?'); ylabel('Les fonctions'); xlabel('Les valeurs'); grid; Il est egalement possible d'avoir simultanement plusieurs graphiques a l'ecran. Pour cela, utiliser la commande subplot(rcn) ou r, c, n sont respectivement le numero de la ligne, de la colonne et du graphique. Ainsi, le graphique (4) de l'annexe est de ni par les codes: x=[-3:.01:3]; y1=exp(-0.5*x.^2)/sqrt(2*pi); y2=sin(x); y3=cos(x); y4=abs(sqrt(x)); clg; subplot(221);plot(x,y1);ylabel('Y1');xlabel('X');title('Gauss'); subplot(222);plot(x,y2);ylabel('Y2');xlabel('X');title('Sin(X)'); subplot(223);plot(x,y3);ylabel('Y3');xlabel('X');title('Cos(X)'); subplot(224);plot(x,y4);ylabel('Y4');xlabel('X');title('Abs(Sqrt(X))'); Pour sauver un graphique dans un chier, il sut d'utiliser l'instruction print. La syntaxe generale est: print -options nom_du_fichier D'autres details sont donnes en annexe (C). 5 Applications economiques: le modele de cycles reels (RBC) L'ob jectif de cette section est de montrer comment resoudre numeriquement, a l'aide de Matlab, le modele d'equilibre general a horizon de vie in ni, dans un cadre stochastique. Ce modele est le cadre de reference des modeles RBC. Le programme est ecrit dans un chier rbc.m, et les resultats de ce programme dans un chier rbc.res. Ainsi, au debut du programme on a les codes suivants: 12 clear delete rbc.res diary rbc.res 5.1 Le modele economique 1. 9 un continuum d'agents identiques, indices par i 2 [0; 1]. 2. Ceux-ci sont a la fois producteur et consommateur, L'agent i maximise la fonction d'utilite suivante: max ci;s;li;s;ki;s+1 X1 s=t Et st " log(ci;s) l 1+ i;s 1 +  # sous la sequence de contraintes suivante: ci;t + ki;t+1  (1 )ki;t + pi;tyi;t 8 t = 1;    ; 1  pi;t prix de la production de l'agent i relativement aux prix des biens consommes,  ki;t, li;t, ci;t et yi;t representent respectivement le stock de capital, le nombre d'heure de travail, la consommation et la production de l'agent i,  les parametres  2 [0; 1), 2 [0; 1) et  2 [0; 1) representent respectivement le taux de depreciation, le facteur d'escompte psychologique et l'inverse de l'elasticite de l'o re de travail Chaque agent a acces a une technologie de production lui permettant de produire yi;t: yi;t = stkm i;t( t li;t) 1m  taux de croissance du P.T. incorpore au travail,  st choc de progres technique, incertitude intrinseque,  fonction de production de l'agent i: rendements constants,  le marche concurrentiel, pi;t = pj;t = 1 8 i; j (le bien nal est le numeraire). En supposant que la contrainte budgetaire de l'agent est saturee a chaque periode (i.e. l'agent utilise ces revenus), le probleme de l'agent i peut se reecrire de la facon suivante: max ks+1 ;li;s X1 s=t Et st " log (ci;s+1) l 1+ i;s 1 +  # avec ci;s = ki;s+1 + (1 )ki;s + sskm i;s( t l i;s) Les conditions d'optimalite de ce probleme sont: 1 ci;t + Et " 1 ci;t+1 1  + @yi;t+1 @ki;t+1 !# = 0 1 ci;t @yi;t @ li;t l  i;t = 0 (1 )ki;s + sskm i;s( t li;s) 1m ci;s = ki;s+1 5.2 Conditions d'equilibre 8 i, les conditions d'optimalite sont identiques: 1 ct = Et  1 ct+1  1  + m yt+1 kt+1  l  t = 1 ct  (1 m) yt lt  Les tra jectoires d'equilibre veri ent egalement: kt+1 = (1 )kt + yt ct yt = stkm t ( t lt) 1m st = s  t1vt ou  2 (0; 1) represente la persistance du choc technologique et vt est une innovation iid. Remarque: Il est possible de reduire la dimension du probleme substituant l'o re de travail par l'expression suivante l t =  (1 m) stkm t ct  1 (+m) ou lt est une fonction de ct, kt et st. 5.3 Sentier de croissance deterministe  hypotheses sur les fonctions de production et d'utilite =) existence d'un sentier de croissance equilibree,  tendance =) progres technique incorpore au travail (fonction de ),  exprimer le modele en variables intensives =) de ater l'ensemble des equations de nissant l'equilib  kt+1 t+1  = (1 )  kt t  +  yt t   ct t   yt t  = st  kt t m l 1m t (1 )  yt t  =  ct t  l +1 t t ct ! =   Et " t+1 ct+1 !

Dans le chier Matlab, ceci se fait de la facon suivante: beta=.99; delta=.025; chi=0; gamma=1.004; rhos=.95; epsilon=.0072; m=.36; mu=m; nu=1-m; phi=gamma^(nu/(1-mu)); Les coecients bi alors peuvent ^etre de nis dans le programme Matlab de la facon suivante: b1=1/(chi- nu +1); b2=mu*(chi+1)*b1; b3=-nu*b1; b4=b2-1; b5=(chi+1)*b1; psi=(1-m)^(-b3); L'etat stationnaire peut alors ^etre calcule par Matlab, etant donne la de nition de ces coecients. Les codes sont les suivants3 : 3 La resolution de cet etat stationnaire peut ^etre e ectue en de nissant une fonction telle que celle donnee dans l'exemple "stea AA=(phi+delta-1)-(1/(beta*m))*(phi-beta*(1-delta)); BB=((phi/beta)-1+delta)*(1/(m*psi)); k=(-(BB^(1/b3))/AA)^(1/(1+(b4/b3))); y=((phi/beta)-1+delta)*(k/m); l=(y/(k^mu))^(1/nu); c=y-(delta+phi-1)*k; I=y-c; Il est alors possible de calculer l'utilite, les utilite marginales, ainsi que les derivees des utilites marginales. Les code sont les suivants: util=log(c)-(1/(1+chi))*(l^(1+chi)); %utilite d'etat stationnaire uc=1/c; %utilite marg de la conso ucc=-1/(c^2); %derive seconde par rapport %\`a la conso xcc=ucc*c/uc; %elasticite de l'utilite marg de la conso ul=-l^chi; %desutilite marg du trav ; ull=-chi*(l^(chi-1)); %derive seconde par rapport au trav xll=ull*l/ul; %elasticite de la desutilite %marg du trav Toutes les equations de nissant la dynamique d'equilibre ont la forme generique suivante: f (~ kt; c~t; st) = Et[g(~ kt+1; ~ct+1; st+1)] Le developpement de Taylor jusqu'au premier ordre permet d'approximer, autour de fk; c; sg, toutes les conditions d'equilibre comme suit, les derivees des fonctions f et g etant evaluees au point (k; c; s): f (k; c; s) + @f @k (~kt k) + @f @c (~ct c) + @f @s (st s) = Et  g(k; c; s) + @g @k (~kt+1 k) + @g @c (~ct+1 c) + @g @s (st+1 s)  () f ;k (~kt k) k + f ;c (~ct c) c + f ;s (st s) s = Et " g;k (~ kt+1 k) k + g;c (~ct+1 c) c + g;s (st+1 () f ;k b kt + f ;ccbt + f ;ssbt = Et h g;k b kt+1 + g;c bct+1 + g;ssbt+1i ou i;j , pour i = f; g et j = k; c; s, sont les elasticites des fonctions f et g par rapport a k, c et s. Par exemple, f ;k = @f @k k f (k;c;s) .

ECONOMIQUE Le cours de grands courants de la pensée économique décrit l’évolution de la pensée économique depuis l’Antiquité. Le premier chapitre (de loin le plus long) présente les diverses conceptions de l’économie et l’émergence des concepts actuels avec les néo-classiques. Les autres chapitres s’attachent à l’histoire des grandes doctrines. 1. L’évolution des instruments d’analyse et des problématiques de l’Antiquité à nos jours : une vue d’ensemble 2. La richesse de la pensée antique 3. La pensée médiévale 4. Les mercantilistes 5. Les physiocrates 6. Les classiques 7. La réaction socialiste, marxiste et non marxiste 8. La réaction méthodologique : l’école historique et l’école institutionnaliste MATHEMATIQUES Le cours de mathématiques est construit de la façon suivante : 1. Equations de droites – programmation linéaire 2. Les polynômes 3. Les logarithmes et les exponentielles 4. Continuité et dérivabilité 5. Le calcul différentiel 6. Etudes de fonctions – développements limités Chaque chapitre est accompagné d’exemples d’applications à l’économie. MACROECONOMIE Dans le cours de macroéconomie, deux chapitres principaux sont traités (en 20 heures) : 1. L’équilibre macro-économique classique 2. L’équilibre macro-économique keynésien STATISTIQUES Le cours de statistiques permet l’étude d’une distribution à une variable. Il est composé de 5 chapitres : 1. Notions statistiques et collecte de données 2. Présentation des données statistiques : tableaux et graphiques 3. Les caractéristiques de tendance centrale des distributions à un caractère 4. Les caractéristiques de dispersion des distributions à un caractère 5. Les caractéristiques de forme et de concentration INTRODUCTION AU DROIT PRIVE Dans le cours d’introduction au droit privé, cinq aspects sont abordés : 1. Le droit et les droits 2. Les sources du droit 3. La mise en œuvre des droits 4. Les sujets de droit 5. La responsabilité délictuelle ECONOMIE DESCRIPTIVE Le cours d’économie descriptive présente, à partir de sujets d’actualité, les concepts de base de la science économique. Les étudiants sont ainsi incités à s’intéresser à l’actualité économique et formés à la décrypter. ECONOMIE D’ENTREPRISE Le cours d’économie d’entreprise aborde les principaux enjeux de la discipline et place les entreprises au cœur du circuit économique. Il revient sur les définitions et les mécanismes élémentaires (comme les facteurs de production, l’investissement, la création de valeur ajoutée et la répartition des revenus), ainsi que sur la diversité de ces entités (tant sur le plan des activités, des statuts juridiques, de la taille ou de la propriété). Ces bases permettent de discuter ensuite les structures et l’organisation des firmes, puis de comprendre la stratégie d’entreprise (démarche, diagnostic, choix…). L’enseignement mêle systématiquement les considérations pratiques aux développements théoriques. COMPTABILITE NATIONALE La comptabilité nationale est le cadre dans lequel sont définies et quantifiées la plupart des notions économiques qui sont la base des études d’économie mais aussi de la compréhension des actualités économiques. Nous allons présenter la logique interne de la comptabilité nationale afin de saisir sa cohérence et son intérêt, mais aussi ses limites et ses problèmes. Plan du cours : Introduction L’approche par les produits L’approche par les revenus Financement des patrimoines La synthèse des résultats : agrégats et TEE 5 Licence Economie - Première année MICROECONOMIE Dans le cours de microéconomie, on aborde les bases de l’analyse microéconomique : la définition de l’économie, la distinction entre micro- et macroéonomie ; la frontière des possibilités de production et le coût d’opportunité, la théorie du consommateur et de la demande ; la théorie du producteur et de l’offre ; les marchés de concurrence parfaite, monopole, oligopole, l’analyse de l’équilibre général. Le plan suivi sera le suivant : Introduction : L’ analyse microéconomique : définition, objectifs et méthodes. Chapitre 1 : Le marché Section 1 : La notion de biens économiques et de marché Section 2 : La fonction de demande Section 3 : La fonction d’offre Section 4 : L’équilibre du marché Chapitre 2 : Le comportement du consommateur Section 1 : Les axiomes de base du comportement du consommateur Section 2 : Utilité et courbes d’indifférence Chapitre 3 : L’équilibre du consommateur Section 1 : La contrainte budgétaire Section 2 : La recherche de l’équilibre du consommateur Section 3 : Le calcul de l’optimum Section 4 : Les modifications de l’équilibre et la demande individuelle Chapitre 4 : La demande du consommateur et son élasticité Section 1 : L'élasticité-prix Section 2 : L'élasticité-revenu Section 3 : L'élasticité croisée Chapitre 5 : Approche de l’entreprise et de sa production Chapitre 6 : La fonction de production de l’entreprise Section 1 : La production avec un seul facteur variable Section 2 : La production avec deux facteurs variables Section 3 : La recherche de l’optimum de production Chapitre 7 : Les coûts de l’entreprise Section 1 : Les coûts de courte période Section 2 : Les coûts de longue période Chapitre 8 : Comportements du producteur sur différent marchés GRANDS PROBLEMES ECONOMIQUES CONTEMPORAINS 1) Aspects microéconomiques : De quelle façon l'économiste analyse-t-il les problèmes d'environnement? La grande entreprise a-t-elle transformé les mécanismes du capitalisme? 2) Aspects macroéconomiques : L'économie du développement L'analyse des crises économiques 3) Aspects à la fois micro et macroéconomiques : Systèmes socialistes et centralisation Libéralisme et interventionnisme MATHEMATIQUES Le cours de mathématiques est construit de la façon suivante : 1. Suites numériques 2. Calcul intégral 3. Equations différentielles 4. Fonctions de plusieurs variables 5. Fonctions homogènes, fonctions implicites 6. Base du calcul matriciel 7. Déterminant et inverse d’une matrice Chaque chapitre est accompagné d’exemples d’applications à l’économie. STATISTIQUES Le cours de statistiques aborde l’étude d’une distribution à deux variables et les notions d’indices et de taux de croissance. Une introduction à la statistique probabiliste est également proposée. Il est composé de 3 chapitres : 1. Statistiques descriptives à deux dimensions (tableaux à double entrée, caractéristiques marginales et conditionnelles, indépendance, liaison fonctionnelle et relative) 2. Taux de croissance et indices (élémentaires et synthétiques) 3. Introduction à la statistique probabiliste (notions de variable aléatoire, de probabilités conditionnelles, …) METHODOLOGIE DU TRAVAIL UNIVERSITAIRE Dans le cours de méthodologie du travail universitaire, les étudiants sont formés aux techniques de prise de notes et de rédaction d’une dissertation. Ils sont également amenés à rechercher de l’information économique et à la présenter sous la meilleure forme. INFORMATIQUE Le cours d’informatique est consacré aux systèmes d’exploitation, à l’internet, aux traitements de textes et aux outils de présentation (préparation de la première partie du C2i). 6 Licence Economie - Première année INTRODUCTION AU DROIT PUBLIC Dans le cours d’introduction au droit public, trois aspects sont abordés : 1. Les notions et principes fondamentaux 2. Les sources du droit public 3. L’organisation constitutionnelle de la Ve République GRANDES FONCTIONS DE L’ENTREPRISE Le cours de grandes fonctions de l’entreprise passe en revue : la fonction de production (en y intégrant la gestion de la qualité, la logistique et la recherche-développement), la fonction commerciale (de la démarche marketing à la force de vente), la fonction comptable et financière, la fonction de gestion des ressources humaines. Ce tour d’horizon mène à l’élaboration d’un système d’information et considère l’entreprise comme un centre de décision. Une synthèse peut alors être réalisée en posant la question de la stratégie de l’entreprise (au niveau global, au niveau des domaines d’activités stratégiques, à l’échelle internationale). SOCIOLOGIE ECONOMIQUE Le cours de sociologie économique s’inscrit dans la continuité du cours de sociologie générale qu’ont reçu les bacheliers ES. Après une brève remise à niveau en sociologie et une présentation des fondateurs de la sociologie économique (Marx, Weber, Mauss), le cours vise à compléter la culture sociologique des étudiants en s’intéressant aux courants contemporains de la sociologie économique. Autour de l’étude des principaux objets de la sociologie économique (l’échange, la coordination, la monnaie, les conventions, les réseaux, la complexité, le travail, etc.), on montre la fécondité de cette approche et l’intérêt qu’elle peut revêtir pour les économistes. L’objectif du cours est donc de faire dialoguer les deux disciplines (économie et sociologie) autour d’objets communs pour montrer comment elles peuvent s’enrichir l’une l’autre dans la compréhension des phénomènes économiques. ECONOMIE EUROPEENNE L’objectif du cours d’économie européenne est de proposer une introduction à l’économie européenne à travers sept grands thèmes : 1. L’économie de l’Union européenne : une approche descriptive 2. Les institutions économiques de l’Union européenne 3. Les théories de l’intégration européenne 4. Les politiques économiques dans la zone Euro 5. La politique agricole commune 6. La concurrence fiscale en Europe 7. Les enjeux de l’élargissement de l’Union à l’est INFORMATIQUE Le cours d’informatique est consacré aux traitements de données, au travail collaboratif, à la sensibilisation au droit et à la déontologie (préparation de la deuxième partie du C2i) LANGUE VIVANTE 1 L’enseignement de langue vivante 1, assuré par le service commun de l’enseignement des langues vivantes (SCELV), porte sur la compréhension orale d’une langue vivante. 7 MACROECONOMIE Dans le cours de macroéconomie, quatre points sont abordés : 1. Analyse approfondie des deux grandes fonctions : consommation et investissement 2. Examen des modèles doctrinaux du côté de la demande 3. Examen des modèles doctrinaux du côté de l’offre 4. Possibilité de synthèse Licence Economie - Deuxième année ECONOMIE MONETAIRE Le cours d’économie monétaire fournit une introduction à la théorie monétaire en trois chapitres : 1. L’utilité de la monnaie 2. La demande de monnaie 3. L’offre de monnaie MATHEMATIQUES Le cours de mathématiques présente les points suivants : 1. Espaces vectoriels 2. Opérations sur les matrices 3. Systèmes d’équations linéaires 4. Vecteurs propres et valeurs propres 5. Fonctions de plusieurs variables réelles 6. Optimisation libre 7. Optimisation contrainte Chaque chapitre est accompagné d'exemples d'applications à l'économie. POLITIQUE DE LA CONCURRENCE Le cours de politique de la concurrence a pour vocation à faire la transition entre les deux cours de microéconomie de L1 (concurrence parfaite) et de L2 (concurrence imparfaite). On montre d’abord comment le modèle de concurrence pure et parfaite peut servir d’étalon afin de juger les situations réelles des marchés. A cet égard, les institutions en charge de la politique de la concurrence sont présentées ainsi que leurs objectifs et la manière dont elles mettent en œuvre leur politique. Puis, on lève progressivement les hypothèses de la concurrence parfaite (atomicité, barrière à l’entrée, ententes) et on introduit de manière non-technique la concurrence imparfaite. L’objectif est ici de faire comprendre les grandes problématiques de la concurrence imparfaite afin de montrer la nécessité d’outils techniques précis pour étudier ces situations (ce qui est fait en Microéconomie II) et pour juger des cas de politique de la concurrence. DEMOGRAPHIE Le cours de démographie répond à trois objectifs : 1. une connaissance des instruments de base de l’analyse démographique, 2. une connaissance des principaux faits démographiques en France, en Europe et dans le monde, 3. une approche empirique et théorique des interactions entre population et économie. Il porte sur les différents phénomènes démographiques (natalité et fécondité, nuptialité, mortalité, migrations). INSTITUTIONS ADMINISTRATIVES L’objectif du cours d’institutions administratives est de sensibiliser les étudiants à l’organisation administrative de la France et à ses modes d’action. Trois parties sont proposées : 1. Présentation générale de l’administration 2. L’administration d’Etat 3. Les collectivités locales GESTION D’ENTREPRISE Le cours de gestion d’entreprise propose aux étudiants une approche concrète des modalités de gestion d’une entreprise, et ce, à partir d’exercices de simulation (jeux d’entreprise). LANGUE VIVANTE 2 Le cours de langue vivante 2, assuré par le service commun de l’enseignement des langues vivantes (SCELV), porte sur la compréhension écrite d’une langue vivante. INFORMATIQUE 1 (Statistiques et probabilités avec Excel) Le cours d’informatique 1 (statistiques et probabilités avec Excel) a pour objet de permettre aux étudiants d’utiliser l’outil informatique pour construire et présenter des travaux de statistiques. Il s’agit de leur montrer comment gérer une base de données, comment construire des tableaux et des graphiques, comment calculer des caractéristiques statistiques, et ce, en insistant sur l’interprétation des résultats obtenus. 8 MICROECONOMIE Le cours de microéconomie reprend les acquis du cours de microéconomie de L1 en exposant les deux théorèmes du bienêtre. En plus, il introduit à l’économie publique (l’Etat comme agent producteur de biens publics et comme agent redistributeur, par le biais de l’impôt et des transferts sociaux) et à la théorie des jeux en concurrence imparfaite (économie industrielle). Licence Economie - Deuxième année POLITIQUES ECONOMIQUES Le cours de politiques économiques présente les différentes politiques économiques conjoncturelles ayant pour objectif de modifier une évolution macroéconomique spontanée jugée sousoptimale. L’introduction permet d’établir et de définir le concept de politique conjoncturelle, de la resituer dans son contexte historique et théorique et de présenter la politique conjoncturelle française depuis 1950. La première partie analyse les deux grands instruments de régulation conjoncturelle : la politique budgétaire et la politique monétaire. La seconde partie se présente comme une application des concepts introduits dans la première aux politiques de lutte contre le chômage. Enfin, la conclusion s’interroge sur la pertinence d’une politique économique conjoncturelle et montre que l’action étatique semble, actuellement, s’orienter vers des actions structurelles de long terme. STATISTIQUES ET PROBABILITES Le cours de statistiques et probabilités propose les cinq points suivants : 1. Probabilités 2. Variables aléatoires 3. Vecteurs aléatoires et lois conditionnelles 4. Principales lois de probabilité 5. Convergences HISTOIRE DES FAITS ECONOMIQUES Le cours d’histoire des faits économiques aux 19e et 20e siècles utilise les principaux concepts acquis en comptabilité nationale et en macroéconomie pour analyser l’évolution des économies européennes (ex URSS incluse) de la révolution industrielle à la fin du 20è siècle. 1. Les méthodes de l’histoire économique 2. La révolution industrielle : histoire et interprétations 3. L’économie française de 1820 à 1914 4. Les spécificités de l’histoire américaine 5. Développement de l’Europe de 1820 à 1914 6. L’ère des crises (1918-1940) : faits et interprétations 7. 1945-2000. Les « trente glorieuses » à la croissance molle COMPTABILITE GENERALE Le cours de comptabilité générale a pour objectif de donner à chaque étudiant les bases de compréhension nécessaires à la lecture et au traitement des principales opérations comptables de l'entreprise. La lecture et la manipulation des états financiers, et notamment de la liasse fiscale, sont en effet indispensables pour tout étudiant d'une filière économie-gestion souhaitant poursuivre sa formation supérieure dans un domaine en rapport avec le monde de l'entreprise. Pour ce faire, nous concilions à la fois l'opératoire, au travers de la tenue d'une comptabilité fictive, et l'analyse en traitant de la logique comptable sous-jacente de façon simple et générale. Aucun pré-requis n'est nécessaire. Le cours est divisé en deux parties. La première s'intéresse aux fondements de la comptabilité générale dans une perspective temporelle ainsi qu'à la mise en évidence de ses principaux objectifs, principes et méthodes. La seconde partie, plus appliquée, traite de la tenue et de l'enregistrement des opérations de constitution, d'exploitation, de financement, d'investissement et d'inventaire. FINANCE D’ENTREPRISE Le cours de finance d’entreprise présente les outils utiles à la gestion des finances d’une entreprise. Sont ainsi abordées, entre autres, les notions de rentabilité, de trésorerie, de liquidité, de choix optimal d’investissement, … . LANGUE VIVANTE 3 L’enseignement de langue vivante 3, assuré par le service commun de l’enseignement des langues vivantes (SCELV), est consacré à l’expression écrite et orale d’une langue vivante. INFORMATIQUE 2 Le cours d’informatique 2 propose une initiation à la création et à la gestion d’une base de données sous Access. Les points suivants sont traités : 1. Analyse fonctionnelle (définition de la notion de bases de données relationnelles) 2. Les tables (création des champs ; définition des propriétés des champs ; création de la clé primaire ; création de liste de choix avec l’assistant ; utilisation et personnalisation du masque de saisie ; définition des relations entre les tables) 3. Les requêtes (création de requêtes de sélections simples) 4. Les formulaires (création de formulaires avec sous formulaire avec l’assistant) 5. Les états (création avec l’assistant) 9 Licence Economie - Troisième année MARCHES ET ACTIFS FINANCIERS L’objet du cours de marchés et actifs financiers est l’étude du marché financier français, ainsi que des grands marchés dérivés de gestion des risques, en se plaçant du point de vue de leur utilisation par les entreprises. L’accent y est mis sur le rôle fondamental des banques. 1. Les financements sur les marchés de valeurs mobilières 2. La gestion du risque de taux d’intérêt sur les marchés de gré à gré 3. La gestion des risques de prix et de change sur les marchés organisés de contrats à terme négociables 4. La gestion du risque boursier sur les marchés organisés d’options négociables MACROECONOMIE APPROFONDIE Le cours de macroéconomie approfondie aborde deux aspects très contemporains de la macroéconomie. Au préalable l’introduction générale définit le champ du cours dans le cadre de la macroéconomie financière. Les problèmes de l’instabilité du cycle économique induite par le cycle du crédit bancaire, ou l’ampleur des déficits budgétaires et de la dette publique, sont abordés, mettant en exergue la macroéconomie du crédit bancaire (Chapitre I) et la macroéconomie des déficits budgétaires (Chapitre II). D’autres problèmes sont signalés en introduction générale mais sans qu’il ne soit possible de leur donner un traitement exhaustif : l’instabilité du cycle économique du fait des décisions d’investissement des firmes privées en régime d’incertitude, ou du fait de l’instabilité financière. Le Chapitre I revient sur le rôle décisif du crédit bancaire dans les économies contemporaines. La Section I montre comment le modèle de base en économie fermée ignore ce rôle, le taux d’intérêt assurant l’équilibre étant celui des actifs financiers. Ce modèle est alors enrichi pour expliquer les raffinements contemporains des fonctions de comportement. Mais surtout, la Credit View est plus exhaustivement abordée (Section II), et ce dans différentes directions, dont la moindre est la mise en évidence du canal du crédit. Le rôle du crédit bancaire dans la détermination du volume d’activité d’équilibre, et surtout dans l’apparition d’une déflation potentielle de l’activité est illustré. Le Chapitre II revient sur la macroéconomie des déficits budgétaires. D’abord à partir des fondements intergénérationnels des transferts redistributifs dans le cadre des ménages dynastiques (Section I). Ensuite avec le rôle central des prévisions rationnelles dans les comportements desdits ménages (Section II). Pour enfin aborder l’échec des politiques de relance par l’emprunt (équivalence ricardienne), lorsque l’Etat « joue contre le secteur privé » dans les pays riches (Section III-A), ou lorsque la stabilisation des déficits publics ignore les contraintes redistributives des ménages dynastiques dans les pays pauvres d’Afrique (Section III-B). ECONOMIQUE PUBLIQUE Le cours d’économie publique s’articule autour de trois parties qui couvrent l’ensemble des domaines traditionnellement étudiés par cette branche de l’économie, essentiellement dans une perspective normative. Ainsi, la première partie traite des fondements de l’économie publique. La deuxième partie est consacrée au rôle de l’Etat dans la correction des défaillances du marché. Enfin, la dernière partie présente une vision plus critique de l’Etat à travers l’analyse des déviances bureaucratiques, de la démocratie et des groupes de pression. DYNAMIQUE ECONOMIQUE Ce cours présente : 1. Les principales approches de la dynamique à long terme, des cycles longs aux théories de la croissance endogène, en les confrontant aux enseignements de l’histoire. 2. Les théories des crises avec une attention particulière aux explications de la crise actuelle comparée à celle de 1929. STATISTIQUE APPROFONDIE Le cours de statistique approfondie propose les trois parties suivantes : 1. Théorie de l’estimation 2. Tests d’hypothèses 3. Introduction à la loi normale multidimensionnelle ECONOMIE DU RISQUE ET DE L’ENVIRONNEMENT Le cours d’économie du risque et de l’environnement est développé en deux parties. La première partie introduit les principales problématiques appréhendées par l’économiste en matière d’environnement (effets externes, bien public, évaluation des biens environnementaux...) et de ressources naturelles (épuisables et renouvelables). Il présente notamment les différentes théories qui ont été développées afin de proposer une gestion optimale des ressources environnementales, ainsi que des instruments de politique environnementale. Sont ensuite abordés des sujets plus pratiques concernant les services d'eau potable, l'écocertification, la déforestation tropicale et la modélisation de filière forestière. L'objectif est de donner une matière pour réfléchir aux questions d'actualité telles que la préservation de la biodiversité, la pertinence d'une taxe carbone, le prix de l'eau... La seconde partie présente l'approche de l'économiste des domaines du risque et de l'incertain. Sont étudiés les outils essentiels de l'analyse microéconomique de l'incertain, tels que la théorie du comportement individuel dans l'incertain, les mesures d'aversion pour le risque et les mesures de risque, la notion d'équivalent certain et les structures d'information. Sont ensuite traités les thèmes de l'assurance et de l'échange en incertain. 10 COMPTABILITE APPROFONDIE Le cours de comptabilité approfondie vise à compléter les connaissances d'étudiants futurs concepteurs ou utilisateurs des comptes. Il traitera de l'application comptable de situations clés de la vie des sociétés. Il s'articulera autour de la connaissance du traitement comptable et des incidences fiscales d'opérations réalisées par les entreprises depuis leur constitution jusqu'à leur fusion ou leur liquidation, en passant par la recherche de sources de financement par capitaux propres ou par endettement. La comptabilité de groupe ainsi que les normes internationales IFRS y seront également abordées en détail. L'objectif principal est d'être capable, à travers la compréhension de la traduction comptable d'opérations fondamentales, de concevoir, analyser, auditer ou utiliser des comptes annuels modifiés par ces opérations. Licence Economie - Troisième année CROISSANCE ET DEVELOPPEMENT DURABLE Le cours de croissance et développement durable vise à apporter aux étudiants des connaissances leur permettant d’appréhender les différentes dimensions du développement durable, économiques, sociales et environnementales. Il inclut une présentation des mécanismes de base de l’analyse de la croissance et du développement ainsi que des acteurs du développement durable, (entreprises socialement responsables, société civile, collectivités territoriales) et du principe de précaution. Les nouveaux modes de fonctionnement de l’économie, tels que l’économie de fonctionnalité ou les symbioses industrielles qui relèvent de l’écologie industrielle sont abordés, ainsi qu’une comparaison des principaux instruments économiques visant à protéger l’environnement, comme les taxes et les permis d’émission négociables. DROIT DU TRAVAIL Le cours de droit du travail présente l’ensemble des règles qui régissent les relations entre les employeurs et les salariés. Ce sont donc les différents aspects du contrat de travail qui sont analysés. ECONOMIE DES ORGANISATIONS Le cours d’économie des organisations présente les principales analyses relatives à l’organisation des systèmes économiques (marchés, entreprises) en se concentrant sur les concepts majeurs de coûts de transaction, d’information, d’aléas moraux, de sélection adverse ou de droits de propriété. De nombreuses applications empiriques de ces concepts sont proposées, abordant ainsi la relation d’emploi, les contrats de franchise ou encore les droits de propriété intellectuelle. 1. Organisation économique et efficacité : coordination, incitation, information 2. Les prix comme mécanisme organisationnel 3. Informations privées et sélection adverse 4. Aléa moral et réputation 5. Les droits de propriété STRATEGIE D’ENTREPRISES Le cours de stratégies d’entreprises présente les avantages et limites de la mise en œuvre des différentes stratégies utilisées par les entreprises en fonction de leur environnement concurrentiel et institutionnel ainsi que de leurs capacités intrinsèques. Cet enseignement conduit à l’analyse des principaux thèmes de l’économie industrielle. ECONOMIE DU TRAVAIL ET DE LA REPARTITION Le cours d’économie du travail et de la répartition est composé de quatre chapitres : 1. Les grandes théories de la répartition du revenu global 2. Chômage et répartition 3. L’offre de travail 4.

PRODUITS BANCAIRES D’EPARGNE DU PARTICULIER Analyse de l’épargne des particuliers, comptes, livrets, plans d’épargne,… GESTION DE OPCVM Produits d’épargne non bancaires, organismes de placement collectif en valeurs mobilières. STATISTIQUES ET ECONOMETRIES APPLIQUEES A LA FINANCE Ce cours est composé de deux parties. La première partie permet de présenter la théorie de l’estimation et différents tests statistiques (test d’égalité de deux moyennes, de deux variances, de deux proportions, test du khi-deux, …). Dans la seconde partie, on propose une introduction à l’économétrie dans laquelle on présente d’abord le modèle de régression linéaire simple que l’on applique à l’analyse du risque de la firme. On s’intéresse ensuite au modèle de régression multiple, en l’appliquant à la théorie de l’évaluation par arbitrage. Enfin, on ouvre sur d’autres types de modèles tels que les modèles à retard échelonnés, les modèles autorégressifs ou les modèles d’ajustement partiel, les tests d’efficience du marché fournissant les applications appropriées. ANALYSE MICROECONOMIQUE Ce cours est scindé en deux parties. La première présente l’analyse néoclassique des marchés concurrentiels : théorie du consommateur, théorie de la firme en équilibre (général) de marché. La seconde propose une introduction à la théorie des jeux (non-coopératifs), à la théorie des choix en environnement incertain et à la théorie des contrats et des incitations. ANALYSE MONETAIRE Ce cours est une introduction aux analyse théoriques des éventuelles conséquences de la présence de la monnaie sur les variables économiques réelles (théorie quantitative de la monnaie, l’approche keynésienne, dilemme inflation-chômage, influence du crédit bancaire sur l’activité économique…). 12 ANALYSE DE DONNEES L’objectif du cours et des TD d’analyse des données est de former les étudiants (ayant choisi cette option) aux principales techniques statistiques permettant, face à des données concernant de nombreux individus et de nombreuses variables (quantitatives ou qualitatives), de résumer au mieux l’information. Cela peut se faire par exemple en créant des groupes d’individus qui se ressemblent, et en caractérisant ensuite chaque groupe par les valeurs moyennes ou les modalités les plus fréquentes de certaines variables. Il s’agit de donner aux étudiants qui le désirent un panorama des diverses techniques d’analyse des données, de leur indiquer les critères de choix entre ces techniques et, pour chacune d’entre elles, de leur fournir des clés d’interprétation des résultats, ainsi qu’une idée claire des limites. Cela se fait, en cours, au moyen d’exemples commentés par le professeur, ce qui rend quasiment nécessaire la participation assidue aux cours, ainsi qu’un travail régulier au fil des semaines. En TD, les étudiants apprennent à interpréter des résultats d'analyse de données, en appliquant les principes indiqués lors des cours. Un groupe de perfectionnement est créé à l'intention des étudiants volontaires pour y participer régulièrement toutes les semaines et pour fournir le travail de révision et de préparation nécessaire. Ils y apprennent, avec l’aide du professeur, à mettre en oeuvre euxmêmes les techniques d'analyse de données, en faisant usage d’un logiciel statistique (SAS) et de macro-programmes INSEE spécialisés. Le plan du cours est le suivant : Chapitre 1 : L’analyse en composantes principales (ACP) Chapitre 2 : L’analyse factorielle des correspondances (AFCSimples et AFCMultiples) Chapitre 3 : Méthodes de classification (CAH, CDH, « k-means », nuées dynamiques) Chapitre 4 : L’analyse factorielle discriminante (AFD) THEORIE DES JEUX La théorie des jeux constitue un ensemble d’outils analytiques qui ont été développés afin de comprendre et étudier les situations d’interaction entre individus rationnels. Elle s’inscrit en cela dans les limites de la théorie de l’Equilibre général, théorie dans laquelle les agents économiques interagissent uniquement par l’intermédiaire du système de prix sur lequel leurs décisions individuelles n’ont aucune influence. L’objectif de ce cours, qui se veut introductif, est de familiariser l’étudiant avec l’utilisation de cette « boîte à outils » via la maîtrise des concepts clés du domaine, à savoir les notions de stratégie dominante, d’équilibre de Nash, d’équilibre de Nash parfait en sous-jeux, ? La maîtrise de ces concepts permettra à l’étudiant d’appréhender diverses situations d’interaction stratégique, telles que la concurrence imparfaite, les enchères, le vote... . Ce cours est composé de 4 grandes parties : 1. Concepts clés : jeux, stratégies et information 2. La déviation dans un jeu : l’équilibre de Nash 3. Dynamique et « rétroduction » 4. Négociation : jeux coopératifs et non coopératifs HISTOIRE DE L’ANALYSE ECONOMIQUE Dans le cours d’histoire de l’analyse économique, on présente les bases anciennes de l'analyse économique : le circuit du capital et la formation des prix. L'adoption du paradigme de concurrence et ses implications analytiques en microéconomie et macroéconomie. Le développement des systèmes d'analyse modernes. Licence Economie - Troisième année ECONOMIE PUBLIQUE APPLIQUEE L’objectif du cours d’économie publique appliquée est de mettre en perspective des exemples marquants d’interventions publiques récentes à la lumière des concepts et des modes de raisonnement développés dans le cours d’économie publique du semestre précédent. Un chapitre préliminaire dresse un état des lieux du poids des pouvoirs publics dans l’économie française. Le corps du cours envisage ensuite, successivement, trois motifs d’intervention publique : la fourniture de biens collectifs, la gestion d’externalités et la redistribution. Les mesures de politique publique présentées et analysées sont choisies dans les domaines classiques d’intervention des pouvoirs publics : politique environnementale, politique énergétique, politique de santé, politique éducative, politique de lutte contre la pauvreté. MONDIALISATION ET ECONOMIE INTERNATIONALE Le cours de mondialisation et économie internationale est composé de trois chapitres : 1. La spécialisation internationale dans le cadre mondial 2. Les déséquilibres de paiements extérieurs et les politiques correctrices 3. La recherche de l’optimisation économique nationale à travers l’échange mondial MARCHES D’ASSURANCE ET DE PROTECTION SOCIALE Le cours de marchés d’assurance et de protection sociale, donné par un professionnel, présente les différents marchés d’assurance (IARD, vie, responsabilité civile, risques majeurs, santé,…) ainsi que les produits adaptés à la gestion des risques considérés. La différence est faite entre les mécanismes de l’assurance (dont le concept support est celui de l’efficacité économique) et ceux qui relèvent de la protection sociale (et donc du concept 13 GESTION D’ENTREPRISE APPLIQUEE Le cours de gestion d’entreprise appliquée (jeu) est un enseignement innovant, qui s’appuie sur l’utilisation d’un logiciel et qui vise à sensibiliser les étudiants à l’interdépendance des décisions, tant entre entreprises sur un même marché qu’au sein de l’entreprise. Licence Economie - Troisième année ANALYSE ECONOMIQUE DES POLITIQUES SOCIALES Le cours d’analyse économique des politiques sociales est centré sur la protection sociale. Après un chapitre introductif présentant les principales typologies des systèmes de protection sociale et les fonctions de la protection sociale, le cours traite du financement de la protection sociale et de ses liens avec l’emploi, puis aborde les différents domaines de la protection sociale (politiques familiales, politiques de la santé, politique des retraites, politiques de lutte contre la pauvreté). METHODES D’ENQUÊTES Le cours de méthodes d’enquêtes permet d’aborder les points suivants : 1. Formuler une problématique appréhendable par enquête 2. Echantillonnage et représentativité 3. Rédaction et test d’un questionnaire 4. Choix du mode de collecte 5. Organisation du protocole d’enquête 6. Après la collecte GOUVERNANCE D’ENTREPRISE L’objectif du cours de gouvernance d’entreprise est de présenter l’ensemble des règles régissant la façon dont l’entreprise est dirigée. Différents aspects sont abordés, notamment le fonctionnement du conseil d’administration, le rôle des actionnaires et celui des dirigeants. DROIT DES AFFAIRES Le cours de droit des affaires permet d’aborder les points suivants : - Présentation d’ensemble des règles juridiques qui régissent la vie des Entreprises. - Le cadre juridique du Droit des Affaires. - Le statut de l’Entreprise.

La gestion des liquidités débute par le budget de trésorerie et un raisonnement en date de valeur. Les instruments de financement et de placement des liquidités sont étudiés dans le contexte bancaire et financier actuels. La gestion de trésorerie est aussi une gestion des risques financiers, parmi lesquels le risque de taux d’intérêt, faisant l’objet de mesures et de couvertures. De même, le risque de change est abordé dans le cadre d’une gestion de trésorerie internationale et d’une gestion de trésorerie de groupe. LANGUE VIVANTE 5 L’enseignement de langue vivante 5, assuré par le service commun de l’enseignement des langues vivantes (SCELV), est consacré à la préparation aux épreuves du certificat de langue CLES2. La part du travail en autonomie est majoritaire dans cet enseignement. ANALYSE DES RISQUES MACROFINANCIERS Dans le cours d’analyse des risques macrofinanciers, il s’agit principalement d’analyser les risques de taux (d’inflation, de change), les risques sur les marchés de capitaux internationaux (liquidité, ....) et la question de la stabilité du système financier. Ces risques affectent autant les entités macroéconomiques (un pays, une zone monétaire, une zone économique, une banque centrale, …) que des entités telles que l’entreprise (financière ou non financière).

Il s'agit d'un cours semestriel d'une trentaine d'heures environ, réparties entre l'étude proprement dite de la vie économique des entreprises dans leur environnement d'une part, des applications d'autre part. Ces dernières qui ont lieu à la fin des cours magistraux sont des études de cas simplifiées dont le but est d'intéresser les étudiants à l'évaluation sommaire et à l'interprétation de quelques indicateurs de performance des entreprises dans leur rôle de création et de répartition de richesses au plan national. Pour ce faire, des documents de travaux dirigés contenant un certain nombre d'exercices d'application sont préalablement distribués aux étudiants et illeur revient de recourir aux diverses formulations présentées dans le cours pour résoudre les problèmes posés dans chaque cas. C'est dans l'intention de faciliter l'assimilation du cours par les étudiants et leur conférer une meilleure aptitude à traiter les exercices qui leur sont soumis dans les séances de travaux dirigés et à leur examen partiel, qu'il nous a paru utile de mettre cette brochure que nous avons conçue à leur disposition. le document comprend: des extraits du cours, une bibliographie, et treize études de cas avec leurs corrigés. la conception des exercices d'application répond à un souci de simplicité et de pédagogie et n'est donc pas à confondre avec la situation réelle fort complexe vécue par les entreprises, dans un environnement national ou international dynamique, que celui-cisoit économique, institutionnel, juridique, administratif, politique ou social. Il est à signaler que les exercices et leurs corrigés ne sont pas nécessairement liés au contenu ou à l'application de tel ou tel plan comptable, mais tout simplement à l'assimilation de quelques notions "comptables", financières ou économiques élémentaires, enseignées dans le cours. 3 Il reste à souhaiter que les étudiants en fassent une bonne utilisation. L'auteur demeure ouvert à toutes observations de nature à permettre l'amélioration du travail accompli. Le Professeur 4 INTRODUCTION A L'ECONOMIE DE L'ENTREPRISE ~ L'Economie de l'Entreprise est une branche de l'économie générale qui étudie les fondements et les mécanismes des actes économiques de l'entreprise. L'objet de cette discipline scientifique étant l'entreprise, il convient de préciser ce qu'est cet agent économique. Dans la théorie économique, la notion d'entreprise correspond à une entité dont la fonction est de produire des biens et des services en combinant des facteurs. Il existe cependant différentes conceptions de l'entreprise et différents types d'entreprises. La définition généralement acceptée de l'entreprise et que l'on retrouve dans les LEXIQUES D'ECONOMIE est la suivante: "L'entreprise est une unité économique autonome, combinant divers facteurs de production, produisant pour la vente, des biens et des services, et distribuant des revenus en contrepartie de l'utilisation des facteurs." En ce sens, les organisations à activité marchande constituent des entreprises. En revanche, les entités à caractère non marchand, celles dont la production n'est pas en principe destinée à une clientèle solvable, ne sont pas des entreprises. C'est le cas des administrations, des organisations à but non lucratif en général, des associations. De la définition de l'entreprise, on peut retenir trois aspects qu'il est nécessaire d'expliciter. Ces aspects sont les suivants: 1- L'entreprise, centre de calcul économique 2- L'entreprise, système commandé 3- L'entreprise en tant qu'organisation 5 1. L'entreDrise est un centre de calcul économiaue A l'origine du calcul économique réside la volonté de l'entrepreneur de réaliser une combinaison rationnelle des facteurs de production. Celle-ci en intégrant le plus possible les dernières innovations au plan scientifique et technologique vise à permettre une meilleure transformation des matières en biens et services de consommation intermédiaire ou finale en vue de satisfaire la demande potentielle. Cela suppose un choix judicieux des ressources productives compte tenu de leur disponibilité et de leur coût de possession. En somme, le calcul économique s'apparente à un calcul d'optimisation sous contraintes: "recherche de la meilleure fonction de production c'est à dire celle qui, tout en minimisant les coûts de production, maximise l'objectif de l'entrepreneur et en particulier, le profit maximum tiré du capital investi". Le calcul économique est donc à la fois: un calcul d'efficacité: comment mobiliser les ressources productives pour atteindre le ou les objectifs que l'on s'est fixés? (Produire et vendre au maximum pour rentabiliser le capital investi), un calcul d'efficience: comment atteindre le ou les objectifs que l'on s'est fixés en utilisant la voie la moins coûteuse? (faire des économies de ressources ou maîtriser les coûts de production). 2. L'entreDrise est un svstème commandé En la présentant comme un système, cela présuppose que l'entreprise se structure autour d'un certain nombre d'éléments qui entretiennent des relations nécessaires entre eux en vue d'assurer un fonctionnement régulier de l'unité de production dans son environnement. Le système réalise des transformations et peut changer d'état au cours du temps sous l'effet des perturbations venues de l'environnement. En tant que système commandé, l'entreprise a des organes de commande dont le rôle est de décider des actions à mener, de choisir les méthodes, de fixer les objectifs, d'apprécier les 6 résultats atteints. Système commandé ou système finalisé, l'entreprise fonctionne dans un environnement incertain qui fait intervenir la notion de risque. Ce risque peut être lié à l'évolution sociale, technologique, économique, politique. Ces perturbations possibles et multiples de l'environnement impliquent que le système soit doté d'organes de prévisions et soit capable de réagir à l'imprévu. Le système est par conséquent, appelé à être flexible. 3. L'entreDrise est une oraanisation On entend par là, un groupe de personnes qui œuvrent en commun à la réalisation de certains objectifs avec des moyens plus ou moins limités. Les personnes membres de l'organisation sont régies dans leur comportement et dans leur fonction par un ensemble de relations professionnelles, sociales, un ensemble de rôles (position dans la hiérarchie), un ensemble de normes (règles de conduite). L'organigramme de l'entreprise est un schéma par lequel on exprime les relations professionnelles, les rôles, c'est à dire la structure organisationnelle que celle-ci a mise en place pour mener à terme ses activités. La bonne marche de l'organisation suppose la résolution de trois types de problèmes: +:+ un problème de coordination: comment assurer la poursuite d'objectifs en commun avec la division du travail, la répartition des tâches? +:+un problème de communication - décision: à partir de quel réseau d'information va-t-on prendre les décisions. Comment assurer la communication dans l'entreprise? +:+un problème d'animation: comment gérer un processus d'intégration des efficacité individuelles par une élévation de la compétence et de la motivation des individus afin d'améliorer l'efficacité organisationnelle? Etant donné que l'économie et l'organisation de l'entreprise sont deux domainesintimementliés, on se trouve en présence d'une disciplined'enseignement 7 assez vaste dont on ne peut épuiser le contenu en une année, encore moins en un semestre comme le veut la répartition officielledes cours. Le plan de cours ainsi proposé aux étudiants de deuxième année s'articule autour d'un certain nombre de points considérés comme essentiels. Il reste entendu qu'un élargissement et un approfondissement de ce plan seront nécessaires pour les étudiants en année de Licence et de Maîtrise. 8 1ère PARTIE IIème PARTIE CORRIGEES [ PLAN DU DOCUMENT] ELEMENTS DE COURS ETUDES DE 9 CAS PREMIERE PARTIE I ELEMENTS DE COURS ~ I.

Mécanismes comptables et financement des entreprises. 10 : LA PLACE DE L'ENTREPRISE DANS LES SYSTEMES ECONOMIQUES Généralités sur les systèmes économiques De façon générale, le système économique est conçu comme étant un ensemble de structures économiques, institutionnelles, juridiques, sociales, mentales, organisées par une société, en vue d'assurer la poursuite et la réalisation des objectifs économiques qui sont essentiels à l'épanouissement collectif et individuel de ses membres. On distingue cinq principaux systèmes économiques historiquement vécus qui sont les suivants: - le système d'économie fermée. C'est l'exemple du domaine féodal, de l'économie villageoise ou paysanne où l'activité économique est toute orientée vers la satisfaction des besoins de ceux qui vivent sur le domaine. Les débouchés de la production sont limités à un domaine précis dont le chef a la pleine disposition des moyens de production et procède à la redistribution du produit, - le système d'économie artisanale ou pré-industrielle en vigueur dans certains pays européens du XIyè et du Xyè siècle. L'organisation économique, juridique et sociale se caractérise par la propriété privée des moyens de production qui sont entre les mains d'artisans indépendants constitués en corps de métiers, dont les règles coutumières déterminent à la fois les conditions de production et la répartition du produit, - le système d'économie capitaliste. Ce système caractéristique depuis le XYIIIè siècle, la plupart des pays d'Europe Occidentale et des Etats Unis. Il L'esprit de l'activité économique est la recherche du profit individuel. L'organisation juridique et sociale se caractérise essentiellement par la propriété privée des moyens de production, la liberté d'entreprise, la neutralité absolue de l'Etat dans l'activité économique. - le système d'économie collectiviste. Ce système a été en vigueur notamment dans l'ex-Union Soviétique, dans les ex- pays socialistes d'Europe de l'Est. On le retrouve encore en Chine populaire, à Cuba, en Corée du Nord. L'esprit de ce système est de substituer à la recherche du profit individuel dans le système capitaliste, la recherche de l'intérêt collectif qui passe par la satisfaction intégrale des besoins de la population. L'organisation juridique et sociale se caractérise par l'appropriation collective des moyens de production. L'Etat, par l'intermédiaire des instances de la planification, assume sans concession la direction de l'activité économique, et répartit le produit national qui en résulte. - le système d'économie corporatiste. Ce système a été vécu dans certains pays pendant les périodes de guerre et de crises sociales majeures (France, Allemagne, Italie, Espagne, Portugal, Amérique Latine). Il a été institué essentiellement, pour permettre à l'Etat d'organiser la vie politique, économique et sociale dans un environnement marqué par des risques de bouleversements de la situation nationale sur tous les plans. Ainsi, les moyens de production restent propriété privée, mais l'Etat joue un rôle d'arbitre et oriente les activités en vue de ce qu'il appelle: l'intérêt général (ou intérêt supérieur de la nation). L'organisation juridique et sociale se caractérise par la création de groupements professionnels (Corporations ou Corps de Métiers) dans lesquels sont élaborées les règles qui régissent l'activité économique, sous le contrôle de l'Etat. 12 Le système d'économie corporatiste n'est ni un système d'économie capitaliste, ni un système d'économie collectiviste. C'est un système dit « d'économie de guerre ou de crise». Les deux systèmes économiques qui ont cependant le plus marqué l'économie mondiale et sur lesquels il convient de revenir, sont: l'économie de marché et l'économie planifiée. : L'ECONOMIE DE MARCHE Elle est issue de l'application des principes du système capitaliste libéral. Ces principes sont les suivants: - La recherche de l'intérêt personnel et le profit. - La propriété privée des biens de production. - La liberté d'entreprise. - La liberté des échanges ou principe du "laisser faire, laisser aller" . - La liberté de la concurrence dans le respect des textes en vigueur. - La régulation de l'activité économique par le marché, lieu où s'effectuent des transactions commerciales qui mettent en présence d'un côté des offreurs (producteurs ou vendeurs de marchandises ou de services), d'un autre, les demandeurs (clients ou consommateurs). Le prix qui se forme résulte de l'arbitrage du marché, c'est à dire de la force respective des demandeurs et des offreurs (structure du marché, atomicité ou molécularité des intervenants, fluidité). Le marché peut se dérouler en un seul endroit ou en plusieurs endroits (marché local, quotidien, hebdomadaire, régional, national, international) ; le produit concerné peut être homogène ou non homogène. On distingue ainsi huit grandes catégories de marché: concurrence, oligopole, duopole, monopole, monopsone, duopsone, oligopsone, monopole bilatéral (Classification de Stackelberg). 13 NOMBRE DE NOMBRE SITUATION VENDEURS D'ACHETEURS DU MARCHE Multitude Multitude Concurrence Petit nombre Multitude Oligopole Deux Multitude Duopole Un Multitude Monopole Multitude Un Monopsone Multitude Deux Duopsone Multitude Petit nombre Oligopsone Un Un Monopsone Bilatéral STRUCTURE DES MARCHES - La non intervention de l'Etat dans l'activité économique. L'Etat devant se comporter en simple garant de la sécurité des personnes et des biens (principe de neutralité ou encore principe de l'Etat gendarme). - L'application de ce principe a connu essentiellement deux phases qui sont les suivantes: - le capitalisme atomistique. Système d'économie de marché en vigueur en Europe aux ISe, Ige siècles, issus des premières applications des principes du libéralisme économique: la liberté d'entreprise, des échanges, de la concurrence la neutralité de l'Etat à travers notamment, une législation du travail peu contraignante, une libre détermination de l'offre et des salaires, la recherche effrénée de l'accumulation et du profit, ont abouti à la naissance de nombreuses petites entreprises (capitalisme de petites unités). De par leur modeste dimension, ces entreprises n'ont que très peu de moyens d'influencer le marché (en termes de fixation de prix et de 14 publicité par exemple). Ce qui a pu donner aux économistes classiques et néoclassiques, l'illusion d'un marché de concurrence pure et parfaite. - le capitalisme moléculaire. Ce système apparaît sous les formes de capitalisme libéral interventionniste depuis la crise de 1929 où l'on prône désormais l'intervention systématique de l'Etat dans l'activité économique (Etat providence), jusqu'au début des années 1980 où avec l'essoufflement et les imperfections constatées dans l'intervention de l'Etat, on en vient à réclamer à nouveau une réduction systématique du poids de l'Etat dans l'activité économique (capitalisme néolibéral ou retour progressif à I'Etat gendarme). Dans un système capitaliste moléculaire, un petit nombre de grandes entreprises domine le marché. Ce système présente les caractéristiques suivantes: - la recherche du profit n'est plus une préoccupation immédiate de l'entreprise. Elle s'opère dans une perspective à moyen terme en passant par la croissance et la paix sociale; - la grande entreprise influence le marché par la différenciation des produits, la publicité, la fixation des prix, l'amélioration des techniques; - le marché impose à l'entreprise certaines contraintes: quantités vendues, qualité des produits; - l'intervention de l'Etat dans la vie économique. Celle-ci peut prendre deux formes. La première forme est d'ordre administratif. C'est la réglementation de l'activité des entreprises: par exemple, réglementation de la fixation des prix dans certains cas, réglementation du travail et des salaires, réglementation du commerce et des affaires, réglementation de la concurrence, institution d'une fiscalité d'entreprise plus ou moins contraignante, réglementation de la circulation des capitaux, réglementation du crédit. 15 On retrouve ici le concept classique d'Etat gendarme où l'Etat joue un rôle de contrôle, de régulation ou d'assainissement de la vie économique. La deuxième forme est d'ordre économique et social. Il s'agit pour l'Etat, de jouer un rôle d'opérateur économique et social en créant des entreprises ou des services publics, seul ou en association avec des opérateurs économiques privés, dans l'objectif de satisfaire des besoins collectifs tels la culture, l'éducation et la recherche, l'urbanisme, l'équipement, la santé, le logement social, l'emploi, l'aménagement du territoire, les communications, certains biens de grande consommation (électricité, gaz, eau, téléphone, hydrocarbure). On retrouve ici aussi le concept keynésien d'Etat providence où l'Etat intervient pour suppléer les insuffisances du secteur privé ou pour éviter des déséquilibres économiques. C'est précisément ce rôle de l'Etat qui est aujourd'hui remis en cause par les partisans du libéralisme économique pur ou les défenseurs du droit de propriété qui voudraient promouvoir l'entreprise privée, comme étant le seul moteur de l'activité économique. C'est du reste l'une des justifications des privatisations observées à 1'heure actuelle. : L'ECONOMIE PLANIFIEE Elle est issue de l'application des principes du système socialiste, dont les plus éminents penseurs sont: KARL MARX, F. ENGELS, LENINE, STALINE, MAO, ENVER HOXA, TITO. Pour atteindre le bien-être collectif qui est la finalité de l'économie planifiée, on a adopté le principe de la collectivisation des biens de production par la suppression de la propriété privée et le principe d'une planification impérative de l'activité économique qui fait de l'Etat le seul centre de décision, par l'intermédiaire d'un organisme central de planification, où l'on détermine les besoins à satisfaire et les programmes de production à exécuter par les entreprises. 16 Dans ce contexte, l'entreprise propriété publique, ou collective, a une autonomie plus réduite qu'en économie de marché. Elle se voit imposer des objectifs de production à réaliser. En contrepartie, elle reçoit des moyens de production de l'Etat (Terre, Capital, Travail, Technologie, Matières). La recherche du profit privé est impossible puisque l'entreprise ne peut agir sur le niveau de ses bénéfices car les salaires et les prix des biens et services qu'elle achète ou qu'elle vend lui sont imposés. Les bénéfices éventuels sont rigoureusement planifiés, puis répartis en fonction des choix opérés par l'autorité centrale de planification. Tout comme les principes du libéralisme économique, les principes du système d'économie socialiste ou collectiviste ont été diversement appliqués dans les différents pays, en raison de l'environnement. 'Î : LES RELATIONS ENTRE L'ENTREPRISE ET LES AUTRES AGENTS ECONOMIQUES L'activité des entreprises est tributaire des relations qu'elles sont en mesure de développer avec d'autres agents dans l'économie nationale. Ces agents peuvent être regroupés en cinq catégories. Ce sont: les Ménages, l'Administration, les Entreprises non Financières, les Institutions Financières, l'Extérieur. Le contenu des relations entre agents dans une économie est représenté par deux sortes de flux, matérialisées dans un circuit économique. On peut montrer ces flux à travers des schémas successifs. Ce sont: - des flux réels ou « physiques» qui portent sur des biens et services ou des facteurs de production - des flux monétaires ou financiers qui constituent les contreparties des flux réels. 17 Biens et :M54.~C:J{'E Biens et services services 'E:N'r~'EP'lUS D'ES 13I'ENS 'ES Recettes 'ET Règlement :M'EN 54.{i'ES des achats S'E~YIC'ES A.

UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC ÉPREUVE DE STATISTIQUE DESCRIPTIVE Filière : Tronc commun (1ère année) Année académique : 2013-2014 Rédigé par : BAHOUAYILA MILONGO Chancel Bardin1 1 E-mail : bardinbahouayila@yahoo.fr / bardin.bahouayila@facebook.com Tel : 05 075 33 71 / 06 837 81 85 UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC INTRODUCTION L’analyse économique se distingue de l’économie que l’on étudie au lycée, principalement par sa démarche. L’économie du lycée est surtout descriptive (elle décrit les systèmes économiques ou l’histoire économique) et aborde les problèmes et théories économiques sur un plan assez général. L’analyse économique par contre adopte en grande partie la démarche hypothético-déductive. C’est à dire qu’on obtient des résultats en partant des hypothèses particulières et ces hypothèses caractérisent complètement le domaine de validité des résultats obtenus. Dans cette démarche les mathématiques sont un outil particulièrement efficace. En effet, les mathématiques permettent de se libérer des contraintes et des ambiguïtés du langage courant et elles nous fournissent un système de représentation objective, protégé des interprétations subjectives diverses. L’économiste doit donc maîtriser tout un ensemble d’outils mathématiques (statistiques, économétrie, etc.) pour conduire son analyse et cela le rapproche dans une certaine mesure de l’ingénieur. Avec cette démarche l’analyse économique aborde des questions de niveaux assez différents : le chômage dans l’économie nationale, l’inflation monétaire, la balance commerciale du pays, mais aussi, l’offre de travail des ménages, la formation des prix sur un marché, les stratégies des entreprises et les processus de concurrence entre les firmes. La dernière partie des questions que nous venons d’évoquer concerne les comportements des agents individuels dans l’économie (entreprises et ménages). Ces questions sont abordées par l’analyse microéconomique qui fait l’objet de ce cours. Les questions de la première partie concernent des phénomènes plus agrégés, qui ne sont observables qu’au niveau d’une économie nationale (un individu peut être au chômage mais le niveau du chômage dans l’économie ne peut être défini au niveau de l’individu). Ces questions sont abordées par l’analyse macroéconomique. L’objet de ce cours est l’analyse microéconomique. Dans ce cours nous allons d’abord présenter quelques notions sur la microéconomie afin de nous familiariser avec le jargon des économistes. Ensuite, nous expliquerons l’équilibre du marché et la détermination du prix, en passant par l’étude des comportements du consommateur et du producteur. Enfin, nous parachèverons avec l’étude de la fonction de la demande. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC CHAPITRE 1 La consommation La consommation se caractérise par l’utilisation des biens et services dans le but de satisfaire un besoin. Ces biens et services peuvent être : détruits immédiatement (consommation finale) ; transformés lors du processus de production (consommation intermédiaire). Certains biens peuvent être utilisés dans le processus de production pendant au moins un an (ce sont des biens durables). L’ensemble de ces biens est appelé capital fixe. La consommation du capital fixe est l’utilisation de ces biens. Par conséquent, une règle pratique consiste à inclure dans les consommations intermédiaires (CI) les biens qui durent moins d'un an, par opposition à l'investissement (formation brute de capital fixe) qui représente l'achat de biens d'équipement durables (plus d'un an). Mais le petit outillage est inclus, même s’il dure plus d’un an. L’usure des actifs fixes (machines, équipements), est exclue des CI ; elle est enregistrée dans la consommation de capital fixe (CCF). Si les CI excluent les acquisitions de biens d’équipement, elles incluent leur location (équipements, bureaux, terrains, etc.). Les logiciels achetés ou produits pour compte propre sont exclus des CI. Les dépenses en munitions sont clairement des CI de la production des services de défense ou de police. Les tanks, canons et autres porte-avions, sont, par contre, des investissements productifs. En fait, des règles complexes ont été mises au point – par exemple, les achats d’armes de l’armée sont des CI, mais les achats d’armes ou de camions blindés de la police sont … des investissements. Les agents économiques L'agent économique est une personne physique ou morale prenant des décisions d'ordre économique. La comptabilité nationale regroupe les agents économiques (ou unités institutionnelles) selon leurs fonctions en six types, appelés secteurs institutionnels : Ménages (y compris les entrepreneurs individuels), Sociétés financières (institutions financières, banque centrale, sociétés d'assurance etc.), Quelques notions sur la microéconomie UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC Sociétés non financières (entreprises), Administrations publiques (État, administrations locales, de sécurité sociale etc.), Institutions sans but lucratif au service des ménages (ISBLSM) « Reste du monde ». Chaque agent économique est caractérisé par ses fonctions dans l'économie (consommation, investissement etc.). L'agent économique est à la base de l'analyse microéconomique, et aussi de la macroéconomie agrégée. La différence entre la microéconomie et la macroéconomie La macroéconomie est l'approche théorique qui étudie l'économie à travers les relations existant entre les grands agrégats économiques (la croissance, le développement, la pauvreté, l’inflation, etc.) La microéconomie (ou micro-économie) est la branche de l'économie qui « analyse les comportements des individus ou des entreprises et leurs choix dans le domaine de la production, de la consommation, de la fixation des prix et des revenus. Elle est le champ privilégié de la théorie néo-classique » 2 . Elle analyse les comportements des agents économiques individuels (la consommation, la production, l’épargne et l’investissement) et de leurs relations sur les différents marchés où s'échangent les produits et les facteurs de production. Le marché Pour les économistes le marché est le lieu physique ou virtuel où se rencontrent l'offre et la demande et où s'opère la détermination du prix d'un bien ou d'un service. Il existe plusieurs types de marchés parmi lesquels on peut citer: Le marché d’emploi : ce marché, désigné aussi par abus de langage comme « marché du travail », est le lieu théorique de rencontre de l'offre d'emploi et de la demande d'emploi. Le travail y est régulé et fait l'objet, dans la majorité des cas, d'une rémunération. Ce marché est rarement à l'équilibre, c'est-à-dire avec une offre égale à la demande. Le plein emploi parfait correspondrait à l'absence de chômage3 . Pour les économistes néoclassiques, le travail est considéré comme une marchandise standard qui suit les règles de l'offre et de la demande et s'ajuste en fonction des quantités et des prix. Cependant, certains économistes keynésiens remettent en cause l’existence d’un marché du travail. Ils considèrent qu'une baisse des salaires a pour conséquence mécanique une baisse de la 2 Dictionnaire d'Economie et de Sciences sociales, Paris , Nathan 1993 3 Rappeler les notions du sous-emploi visible (heures de travail), sous-emploi invisible (revenu, declassement) et du chôme élargi. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC demande, donc des besoins de production et, au final, de la demande de travail. Pour eux, il n’existe pas de mécanisme de régulation du marché du travail. Le marché des changes : c’est le marché sur lequel les devises sont échangées l’une contre l’autre à des taux de change qui varient sans cesse. Le marché des capitaux : ce marché permet la rencontre entre les agents économiques ayant un excédent de capitaux et les agents ayant des besoins de financement. Ils se subdivisent en trois compartiments : le marché financier, marché monétaire et le marché obligataire.  Les marchés financiers sont les marchés sur lesquels se rencontrent les demandes et les offres de capitaux à long terme. Le marché financier primaire repose sur l'émission nouvelle d'actions et d'obligations alors que le marché financier secondaire est lui le marché où s'échangent les titres déjà émis. C'est ce marché secondaire qui est traité par les bourses des valeurs mobilières (Wall Street, Douala Stock Exchange : DSX, Bourse des Valeurs Mobilières de l’Afrique Centrale : BMVAC par exemple).  Les marchés monétaires désignent les marchés informels où les institutions financières (Trésors nationaux, banques centrales, banques commerciales, assureurs, etc.) et les grandes entreprises (marché des billets de trésorerie) placent leurs avoirs (DAV) ou empruntent (Compte à vue) à court terme (moins d'un ou deux ans) ;  Le marché obligataire est le marché sur lequel les entreprises ainsi que les États se financent. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC CHAPITRE 2 Dans ce chapitre, nous allons expliquer comment le consommateur choisit parmi tous les biens et services disponibles dans l'économie ceux qu'il désire acquérir et en quelles quantités. Le consommateur Le consommateur est un agent économique dont la caractéristique dans l’économie est l’acquisition et la consommation de biens et services grâce à un revenu donné. Il est relié aux entreprises par: son travail; un travail qui lui procure un salaire (rémunération). l’achat de biens et services produits, offerts par l’entreprise. Le consommateur peut être une personne seule, un ménage avec ou sans enfants, ou une communauté. Le consommateur fait son choix de consommation parmi toutes les options qui lui sont ouvertes. Ces options correspondent à toutes les combinaisons possibles de quantités de biens de consommation. Chaque combinaison est appelée un panier de consommation. Nous n’ignorons pas qu’il existe une infinité de paniers à la disposition des consommateurs. Le consommateur classe tous les paniers de consommations par ordre de préférence. La notion de préférence Soit A et B deux paniers de consommation, on distingue : la relation de préférence stricte : Le panier A est strictement préféré au panier B : la relation d’indifférence : Le consommateur est indifférent entre la consommation du panier A ou B quand ils lui procurent la même satisfaction : La relation « préféré ou indifférent » : Les relations (1) et (2) peuvent être combinées en une seule relation : Le panier A est ‘‘au moins aussi désiré’’ que le panier B. La notion de RATIONNALITé Tout consommateur dont le comportement satisfait les 3 axiomes suivants est supposé rationnel : L’axiome de totalité : Tout consommateur est capable de comparer tout panier de biens à un autre de l’ensemble de consommation. Il n’y a pas de panier inclassable par le consommateur. Le consommateur doit pouvoir comparer les 2 paniers A et B : ou L’axiome de réflexivité : Tout panier est indifférent à lui-même: Cet axiome présente un intérêt purement mathématique. Comportement du consommateur UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC L’axiome de transitivité : La relation de préférence est transitive ce qui pourrait conduire à des situations de préférences suivantes: La notion d’UtiLITé Pour représenter les préférences ou les goûts des consommateurs, les économistes ont d'abord eu recours à la notion d'utilité. Le consommateur achète un certain bien parce qu'il lui procure une certaine satisfaction. S'il préfère du foufou le matin à une tasse de lait, dans certaines circonstances, c'est que le foufou lui procure plus d'utilité que le lait. Formellement, on définit sur l'ensemble des consommations possibles une fonction U, dite fonction d'utilité. La fonction d'utilité introduit une relation de préférences sur l'ensemble des consommations possibles. On dit qu'un panier de consommation 𝑋 1 est préféré à un panier 𝑋 2 si et seulement si 𝑈(𝑋 1 ) ≥ 𝑈(𝑋 2 ). On note cette relation On en déduit aussi que 𝑿 𝟏~𝑿 𝟐 ⇔ 𝑼(𝑿 𝟏 ) = 𝑼(𝑿 𝟐 ) Si la notion d'utilité correspond bien à l'intuition, elle n'est pas cependant sans poser un problème sérieux, celui de la mesure. En effet, l'utilité est subjective et difficilement mesurable. Les économistes ont d'abord raisonné comme si l'utilité était mesurable et ont construit des fonctions d'utilité cardinales où l'utilité est mesurée en termes d'unités appelées "utils". Les économistes modernes se sont néanmoins débarrassés de cette vision peu réaliste et raisonnent maintenant en termes d'utilité ordinale. Ils supposent seulement qu'il est possible d'ordonner les satisfactions procurées par deux paniers différents de consommation, sans attacher à chacun des deux paniers un nombre particulier d'utils. La notion de coUrbe et de carte d’indiFFÉrence Soit un panier de consommation x1 qui procure un niveau de satisfaction U0. Le consommateur peut accepter moins d'un bien contre plus d'un autre bien et garder le même niveau de satisfaction. Par exemple, il peut accepter d'avoir 2 kg de lait de moins pour 1 kg de foufou de plus. Ceci exprime une propriété fréquemment répandue dans l'économie : les biens sont substituables entre eux du point de vue de leur faculté de procurer de la satisfaction au consommateur. Comment se fait donc cette substitution ? Nous allons nous intéresser, pour simplifier, à toutes les combinaisons de consommation de deux biens (x1 , x 2 ) qui donnent la même satisfaction. Ces combinaisons sont représentées dans le plan (x1 , x 2 ) par une courbe C0. Parce que les paniers de consommation représentés par des points sur la courbe C0 donnent tous la même satisfaction, ils sont tous équivalents. Par exemple x1 ~ x 2 . Le consommateur est indifférent entre tous ces paniers. C'est pourquoi cette courbe est appelée courbe d'indifférence UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC (figure 1.1). La courbe d’indifférence étant une représentation de tous les paniers considérés par le consommateur comme équivalents, donc procurant la même utilité, la forme de cette courbe reflète la manière avec laquelle des quantités de différents biens contribuent à procurer un certain niveau de satisfaction au consommateur. Lorsqu'on fait varier le niveau de satisfaction on obtient d'autres courbes d'indifférence, correspondant chacune à un certain niveau de satisfaction. Par exemple la courbe C1 située au-dessus de C0 correspond à tous les paniers de consommation donnant un niveau d'utilité U1 > U0. Par contre la courbe C2 située au-dessous de C0 représente les paniers de consommation procurant une satisfaction U2 < U0. L'ensemble des courbes d'indifférence d'un même consommateur forment sa carte d'indifférence (figure 1.2). La notion DU TAUX MARGINAL DE SUBSTITUTION En se déplaçant le long d'une courbe d'indifférence de gauche à droite (figure 1.3) on substitue du bien 1 (bien alimentaire) au bien 2 (vêtements), c'est-à-dire qu'on consomme de moins en moins de vêtements et de plus en plus de biens alimentaires. En se déplaçant de droite à gauche on substitue au contraire le bien 2 au bien 1. Soit un panier de consommation représenté par le point A(x1 0 , x2 0 ) et procurant une satisfaction U0. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC Considérons maintenant une petite augmentation ∆X2 du bien 2. Pour que la satisfaction ne change pas, il faut qu'il y ait diminution de la consommation du bien 1. Soit ∆X1 < 0 cette diminution. Cette substitution du bien 2 au bien 1 est représentée par le déplacement du point A à un point B proche de A et situé sur la même courbe d’indifférence (figure 1.3). Le rapport − ∆X1 ∆X2 est appelé Taux Marginal de Substitution du bien 2 au bien 1 entre les points A et B de la courbe d’indifférence. Il est noté TMS2/1(A, B). Géométriquement, il est représenté par la valeur absolue de la pente de la droite qui relie les points A et B. Le TMS2/1 exprime ainsi la quantité du bien 2 que le consommateur exige si on lui demande de céder une unité supplémentaire du bien 1 (∆X1 = -1). C’est donc la valeur psychologique qu’attache le consommateur à une unité du bien 1. Cette valeur est exprimée en unités du bien 2. Le TMS du bien 1 au bien 2 est l’inverse du TMS du bien 2 au bien 1. Par conséquent : TMS1/2. TMS2/1 = 1 En gros, le Taux Marginal de Substitution de X à Y noté TMSX/Y est la quantité du bien Y à laquelle il faut renoncer pour avoir une unité supplémentaire du bien X tout en gardant constant le même niveau d’utilité. On définit le taux marginal de substitution entre le bien x et le bien y comme suit : 𝑇𝑀𝑆𝑋/𝑌 = − ∆𝑌 ∆𝑋 = − 𝑑𝑈 𝑑𝑋 𝑑𝑈 𝑑𝑌 = 𝑈𝑚𝑋 𝑈𝑚𝑌 Umx est l’utilité marginale du bien X. En effet, l’utilité marginale d’un bien est le supplément d’utilité procurée par la consommation d’une unité supplémentaire de ce bien, toutes choses étant égale par ailleurs. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC L’utilité marginale d’un bien est toujours décroissante car l’utilité procurée par la dernière unité consommée décroit au fur et à mesure que le consommateur augmente sa consommation de ce bien. Exemple : Un voyageur dans le désert qui a soif. Le premier verre d’eau lui procure une grande utilité. Le deuxième verre lui procure une moindre utilité. . . Le nième verre lui procure une satisfaction très faible voire négative (s’il ne peut plus boire). Cet exemple montre que l’utilité marginale de l’eau est décroissante. La NOTION DE LA contrainte budgétaire Etant donné que notre consommateur possède un revenu R déterminé et que les biens 1 et 2 ont respectivement les prix suivants : P1 et P2, alors notre consommateur ne peut pas les acheter que dans la limite de son revenu. D’où on définit la contrainte budgétaire (CB) comme l’ensemble des combinaisons des deux biens (1, 2) donnant lieu à une dépense égale au revenu du consommateur. Dans ce cas, le consommateur doit répartir son revenu entre les deux biens en tenant compte de leurs prix relatifs. Sa contrainte budgétaire s’écrit alors R = P1 ∗ X1 + P2 ∗ X2. La représentation graphique de la contrainte budgétaire (CB) passe par la détermination de ses points extrêmes : Pour X1 = 0 alors X2 =R/P2 ; Pour X2 = 0 alors X1 =R/P1 Une variation des prix des biens 1 et 2 ou de revenu R est accompagnée graphiquement par un déplacement de la contrainte budgétaire comme le décrit le schéma suivant : UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC Tous les paniers situés en dessous de la CB sont accessibles au consommateur. Par contre, le consommateur n’a pas les moyens d’acquérir les paniers situés en dessus de la CB. Le problème du consommateur est de choisir parmi les paniers qui lui sont accessibles celui/ceux qui lui permettent de maximiser son utilité. Il existe 2 méthodes pour résoudre le problème du consommateur : 1 ère méthode Puisque il s’agit d’un problème de maximisation ( le consommateur cherche toujours à maximiser sa satisfaction ou son utilité), on peut donc utiliser le Lagrangien. Tout d’abord il faut écrire le programme du consommateur A ce programme on peut associer la fonction du Lagrange (ou Lagrangien) suivant : Les conditions de premier ordre du Lagrangien sont: Les équations (1) et (2) permettent de déduire que : L’équation (3) permet de s’assurer que la CB est saturée. A l’optimum, la pente de la CI donnée par -Ux1/Ux2 doit être identique à celle de la CB donnée par –p1/p2. 2 ème méthode La détermination de l’équilibre passe par la résolution du modèle à deux équations et deux inconnues suivant : { 𝑇𝑀𝑆 = 𝑈𝑚1 𝑈𝑚2 = 𝑃1 𝑃2 𝑆/𝑐 𝑅 = 𝑃1 ∗ 𝑋1 + 𝑃2 ∗ 𝑋2 UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC CHAPITRE 3 Pour de nombreux économistes, réduire le rôle de l’entreprise à celui de simple producteur ne permet pas de comprendre et de saisir toute la complexité de l’acte de produire, d’organiser et de manager l’entreprise. En tant que producteur, l’entreprise dispose de facteurs de production, nécessairement limités. Les ressources étant rares, il est important de les employer du mieux possible. Généralement, les économistes utilisent une fonction de production pour décrire la relation entre les quantités produites (Y) et les quantités de facteurs de production. Cette approche consiste à définir une relation de transformation d’inputs (intrants ou facteur de production) en output, c’est à dire une fonction de production. Cette fonction permet d’étudier les techniques de production et de choisir la combinaison qui permet d’atteindre l’optimum de production. Pour vérifier l’efficacité de la combinaison productive, on calcule la productivité La productivité La productivité apparaît généralement sous la forme d’un rapport entre la production totale et un facteur de production. La productivité indique comment varie la production totale lorsque l’on fait varier l’un des facteurs de production. On recherche en d’autres termes à préciser la contribution du facteur de production à la croissance de la production. On retient en général deux mesures de la productivité : la productivité moyenne (ou produit moyen) et la productivité marginale (ou produit marginal). La productivité moyenne : Elle exprime la contribution de chaque unité du facteur utilisé dans la production totale. Si l’on suppose que Y est la production totale et que les facteurs de production sont des Xi , alors la production moyenne, notée PM serait : 𝑃𝑀(𝑋𝑖) = 𝑌 𝑋𝑖 La productivité marginale: Elle détermine la production supplémentaire suite à l’utilisation d’une unité de plus du facteur de production. Si l’on suppose que Y est la production totale et que les facteurs de production sont des Xi , alors la production marginale, notée Pm serait : 𝑃𝑚(𝑋𝑖) = 𝜕𝑌 𝜕𝑋𝑖 Comportement du producteur UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC Les facteurs de production Définition Il s’agit des moyens engagés dans les différents processus de la production. Propriétés On peut distinguer les différents facteurs de production selon plusieurs critères. En premier lieu, la provenance des facteurs utilises par la firme permet de distinguer entre les matières premières et les consommations intermédiaires. Les facteurs qui sont directement extraits de la nature (du bois, du charbon, de l’eau) sont des matières premières. Les facteurs qui sont le produit d’une autre firme (du papier, de l’acier, de l’eau lourde) sont des consommations intermédiaires. Certains facteurs de production sont fixes d’autres sont variables. On suppose en général que les équipements lourds comme les bâtiments ou les machines d’une usine (le capital de la firme) et la terre correspondent à des facteurs fixes, tandis que la main d’œuvre (le travail) et les matières premières sont des facteurs variables. Les facteurs de production peuvent être complémentaires (combinés dans les mêmes proportions) ou substituables (remplacer une certaine quantité d’un des facteurs par une quantité supplémentaire de l’autre tout en gardant le même niveau de production). On retient généralement deux facteurs de production : le travail et le capital. 1-Le facteur travail La production réalisée est généralement liée à la quantité de travail disponible et à la qualité de la main d’œuvre. La mesure de la richesse produite par le facteur travail est généralement appréhendée par ce que l’on nomme « productivité du travail ». a- L’approche quantitative du facteur travail La population active est définie comme l’ensemble des personnes en âge de travailler, ayant ou recherchant une activité rémunérée. Elle rassemble donc par convention : les personnes ayant un emploi (actifs occupés) et les chômeurs au sens du BIT (Bureau International du Travail). L’évolution de la population active est liée au taux d’activité, définis comme le rapport entre le nombre d’actifs et l’effectif total des personnes ayant de travailler. La quantité de travail disponible résulte non seulement du nombre de personnes désirant travailler, mais également de la durée moyenne du travail. A cet égard, on peut observer deux phénomènes : l’augmentation du nombre d’emplois à temps partiel et la réduction de la durée du travail. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC La réduction de la durée du travail porte sur la durée de vie. Il y a un siècle, un ouvrier travaillait jusqu’à la fin de son existence, sans retraite. Aujourd’hui l’âge moyen de départ à la retraite au Congo est de 65 ans. En 1850, un ouvrier travaillait 3 000 heures par an, sans week-end ni vacances, aujourd’hui la plupart des salariés bénéficient de weekends de deux jours ainsi que de quelques semaines de congés payés ou non. b- L’approche qualitative du facteur travail Au sein d’une entreprise, d’une branche à l’autre, le facteur travail est rarement homogène. Sa diversité est généralement appréhendée sous l’angle de la répartition par âge, par sexe, par qualification et par Catégories Socioprofessionnelles de la population active. L’âge des salariés est une variable prise en compte par les entreprises dans leur politique de gestion du personnel. Les salariés les plus âgés sont nécessaires à l’entreprise en raison de l’expérience qu’ils ont acquise et qu’ils peuvent transmettre. Les jeunes salariés sont susceptibles quant à eux d’apporter des connaissances théoriques récentes, un certain dynamisme et un esprit d’innovation. C’est pourquoi l’entreprise essaie régulièrement de bâtir une pyramide des âges optimale. Le sexe de la population active, et plus précisément la féminisation de l’emploi est un phénomène majeur des sociétés occidentales contemporaines. En France, le taux d’activité des femmes de 25 à 49 ans, qui était en 1970 inférieur à 50%, tourne aujourd’hui autour de 80%. Les écarts entre les différents pays de la Communauté Européenne sont relativement disparates (en Italie, ce taux est passé de 35% à 45%). Bien que cette tendance concerne toutes les professions, il reste cependant plus marqué dans certaines catégories socioprofessionnelles. La qualification requise de la main d’œuvre est différente selon les emplois, mais elle a souvent des fondements communs. On parle généralement d’emplois à dominante de technicité et d’emplois à dominante d’organisation. En ce qui concerne les emplois à dominante de technicité, la qualification repose sur un savoir-faire permettant d’utiliser l’outil (la machine, l’ordinateur...), de repérer d’éventuelles défaillances et d’y remédier. Ce savoir-faire doit sans cesse s’adapter et évoluer. Au niveau des emplois à dominante d’organisation, la qualification suppose sur la capacité d’organisation, l’aptitude au commandement et la maîtrise de plusieurs activités (polyvalence des cadres). La qualification nécessite au préalable une formation, toutefois la grille des qualifications (c’est-à-dire la grille définie par les Conventions Collectives) ne se calque pas entièrement sur les niveaux de formation. La qualification exige en effet l’acquisition d’une expérience professionnelle plus ou moins longue selon les cas. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC c- La productivité du travail La productivité est au cœur du débat économique. Sans elle, pas de progrès du niveau de vie, ni réduction du temps de travail. La croissance de la productivité détermine en effet les revenus réels, le taux d’inflation et le taux d’intérêt, les profits et les cours boursiers. La productivité du travail indique la contribution du facteur travail à la croissance de la production. On recherche en d’autres termes à préciser comment varie la production totale lorsque l’on fait varier le facteur travail. On appelle productivité moyenne du travail (ou production par tête), le rapport production sur facteur travail. Si Y représente la production et L le travail, alors la productivité moyenne est égale à Y/L. La productivité moyenne du travail peut être définie comme la quantité produite soit par salarié, soit par heure de travail. En pratique, la mesure la plus utilisée est la production horaire par travailleur dans le secteur industriel. L’inverse de la productivité moyenne du travail est appelée : le coefficient d’utilisation de la main d’œuvre, notée u=L/Y. On appelle productivité marginale du travail, la variation de la production engendrée par une variation du facteur travail (c’est à dire d’une unité supplémentaire de facteur travail). La productivité marginale du travail peut être définie comme la quantité supplémentaire produite à l’aide d’un salarié nouveau, ou d’une heure additionnelle. Certaines observations tirées de l’agriculture, ont montré que lorsque l’on augmentait l’utilisation du facteur travail, les autres facteurs demeurant fixes, à partir d’un certain seuil, la productivité marginale du travail diminuait. Tableau 1 : Productivité moyenne et marginale d’un travailleur Ce résultat, observé dès le XVIIIème siècle et plus connu sous le nom de loi des rendements décroissants, a une importance capitale pour l’entreprise, puisqu’il lui permet de comparer le produit d’un salarié supplémentaire (c’est-à-dire d’une embauche) avec son coût. Si le produit d’un salarié UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC supplémentaire est appréhendé par la productivité marginale du travail, et le coût par le salaire, on obtient alors la règle suivante : L’entreprise embauchera des salariés jusqu’à ce que la productivité marginale du travail soit égale au salaire (𝜔) : ∆𝑌 ∆𝐿 = 𝜔 Lorsque la productivité marginale du travail est supérieure au coût du travail (salaire), on considère que l’entreprise réalise des gains de productivité. L’origine de ces gains peut être très diverse : il peut s’agir de l’amélioration de la qualité ou de l’intensité du travail, du progrès technique, de la quantité de facteur capital mis à la disposition du salarié. 2-Le facteur capital Dans son ouvrage « Des principes de l’économie politique et de l’impôt », David Ricardo (1821, [1977, p. 83]) proposait une conception large du capital : « Le capital est cette partie de la richesse d’une nation qui est employée à la production. Il se compose des matières alimentaires, des vêtements, des instruments et ustensiles, des machines, des matières premières, etc., nécessaires pour rendre le travail productif ». D’une certaine manière, on peut considérer que le facteur capital est protéiforme. On parle à la fois de capital fixe, capital technique, capital circulant, capital immatériel… Sa mesure passe par le calcul de la productivité moyenne et de la productivité marginale afin de les comparer au coût de l’investissement. a- Les différents concepts du capital Le capital est un concept qui recouvre plusieurs réalités. C’est un bien qui est produit, non pour satisfaire directement des besoins, mais pour permettre de produire d’autres biens. On appelle capital technique, l’ensemble des biens de production utilisés par l’entreprise, que ceux-ci soient détruits au cours du processus de production (matières premières) ou qu’ils puissent servir à plusieurs reprises (biens d’équipement). Le capital technique est généralement composé de capital fixe (terrains, bâtiments, installations, machines), non détruit au cours du processus de production (utilisé sur plusieurs périodes) et de capital circulant (énergie, matières premières, produits semi-finis), transformé et incorporé au produit au cours du processus de production (détruit au cours de la période). On peut noter dans nos sociétés, une forte dématérialisation du capital. Ainsi du matériel informatique ne peut fonctionner sans logiciels. Ces derniers étant assimilés à du capital immatériel. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC L’accroissement du rôle de l’Etat dans l’économie, illustrée par la politique des grands travaux (tels que les autoroutes, les routes, chemin de fer, aéroports, ports...) fait apparaître une autre forme de capital. Ce capital appelé capital improductif car il ne participe pas directement à la production, mais est constitué de biens d’équipement collectifs. L’acquisition de ce capital physique stipule cependant que l’entreprise dispose à l’origine de moyens de paiements que l’on désigne sous le nom de d’un capital financier. L’origine de ce capital financier peut être très diverse, il peut s’agir : de l’autofinancement d’une émission de titres sur le marché financier, d’une émission d’un emprunt ou d’un don. b- Le capital humain Le capital constitue un stock de ressources permettant de donner naissance à un flux de revenus futurs. Pour Gary Becker, Prix Nobel d’Economie, cette définition ne s’applique pas seulement au capital matériel, mais également à un autre facteur qu’il appelle capital humain. Cette notion n’est pas nouvelle, elle était déjà présente dans l’ouvrage d’Adam Smith, « Recherches sur la nature et les causes de la richesse (1776) ». Adam Smith considérait que les fonds accumulés par un pays pouvaient être décomposés en trois types : (i) le fonds destiné à servir immédiatement à la consommation et dont le caractère distinctif est de ne rapporter aucun profit ou revenu (vivres, habits, meubles, maison d’habitation…) ; (ii) le fonds capital circulant (argent, vivres, matières premières, ouvrage d’un artisan…) dont la spécificité est de ne rapporter de revenu qu’en circulant ou en changeant de propriétaire ; (iii) le fonds capital fixe susceptible de rapporter un revenu ou un profit sans changer de propriétaire. Ce fonds pouvait prendre la forme de machines, de bâtiments, de terres (tout ce qui a été utilisé pour améliorer ses rendements) et de talents. Ce sont ces derniers qui renvoient au concept de capital humain. Adam Smith (1776, [1991, p. 361]) note que « l’acquisition de ces talents coûte toujours une dépense réelle produite par l’entretien de celui qui les acquiert, pendant le temps de son éducation, de son apprentissage ou de ses études, et cette dépense est un capital fixé et réalisé pour ainsi dire, dans sa personne. Si ces talents composent pareillement une partie de la fortune de la société à laquelle il appartient. La dextérité perfectionnée, dans un ouvrier, peut être considérée sous un même point de vue qu’une machine ou un instrument d’industrie qui facilite et abrège le travail, et qui, malgré la dépense qu’il a coûté, restitue cette dépense avec un profit ». Gary Becker a montré qu’un certain nombre de dépenses, assimilables à des investissements, permettent de valoriser les ressources de ce capital humain et d’accroître sa productivité. Ces investissements en capital humain peuvent être : des investissements en éducation et en formation (initiale ou continue) UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC des dépenses de santé et d’hygiène pouvant avoir des effets bénéfiques sur le long terme (idée de préserver certaines facultés intellectuelles ou physiques) le temps consacré à la recherche d’un emploi. Il s’agit d’une comparaison entre le coût de la recherche (coût temporel, consultation de revues, achats de journaux, entretiens, rédaction de CV...) et les gains escomptés de la recherche (salaire, possibilité de promotion, qualité de travail, avantages en nature...). Tous ces investissements ont un coût, cependant ils doivent être entrepris dans l’expectative de gains futurs. G.S Becker propose à cet effet, un critère de choix de l’investissement en capital humain : les individus rationnels devraient sélectionner leurs investissements en capital humain de telle sorte que la somme des bénéfices escomptés dans le temps soit supérieure au coût actuel de l’investissement. Au niveau de l’économie prise dans son ensemble et à long terme, on peut considérer que les dépenses d’investissement en capital humain (éducation, formation continue, stage) sont des facteurs de croissance économique. c. La productivité du capital Le capital peut être appréhendé à partir des notions de productivités. La productivité moyenne du capital est la quantité produite par unité de capital utilisée. Si Y est la production et K le capital, alors la productivité moyenne est égale à Y/K. La productivité moyenne du capital peut être définie comme la quantité produite par machine. Son inverse est appelé : coefficient de capital, noté v=K/Y. Le rapport K/L est appelé intensité capitalistique. La productivité marginale du capital mesure la variation de la production engendrée par une variation du facteur capital. Soit le rapport 𝜕𝑌/𝜕𝐾. La productivité marginale du capital peut être définie comme la quantité supplémentaire produite à l’aide d’une nouvelle machine. L’utilisation accrue du facteur capital, les autres facteurs de production restant fixes et sans progrès technique, conduit à la loi des rendements décroissants. On obtient alors la règle suivante : L’entreprise utilisera du capital jusqu’à ce que la productivité marginale du capital soit égale au taux d’intérêt. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC 3-Le Progrès technique On peut définir le progrès technique comme une nouvelle manière de faire qui permet de produire plus de produits avec la même quantité des deux facteurs de production à savoir le travail et le capital. De façon plus détaillée, P. Ralle et D. Guellec expliquent que « le progrès technique est défini de façon générale comme un accroissement de la connaissance que les hommes ont des lois de la nature appliquées à la production. Il consiste donc de l’invention de produits et procédés nouveaux, qui augmentent le bien-être des individus soit par un accroissement soit par une transformation de la consommation ». Dans les théories de la croissance économique, le progrès technique est désigné comme l’ensemble des éléments qui contribuent à l’augmentation de la production au-delà de ce qui est expliqué par le capital et le travail. Le progrès technique est alors considéré comme un troisième facteur de production. L’isoqUante Nous allons supposer, pour simplifier, que la production résulte de la combinaison de deux facteurs de production: 𝑌 = 𝑓(𝑋1, 𝑋2) Une isoquante (ou un isoquant) est le lieu géométrique de toutes les combinaisons de facteurs correspondant à un même niveau de production. C’est ce que nous avons appelé par la courbe d’indifférence dans le chapitre précédent. Lorsque les facteurs de production sont substituables, on peut définir un taux marginal de substitution des facteurs. Pour faire la différence entre la substitution des produits de consommation et celle des facteurs de production, on parle respectivement de taux marginal de substitution subjectif (TMSS) et de taux marginal de substitution technique (TMST). De ce fait : 𝑻𝑴𝑺𝑺𝑿𝟏/𝑿𝟐 = − 𝑼𝒎𝑿𝟏 𝑼𝒎𝑿𝟐 𝒆𝒕 𝑻𝑴𝑺𝑻𝑿𝟏/𝑿𝟐 = − 𝑷𝒎𝑿𝟏 𝑷𝒎𝑿𝟐 La fonction homogene Soit une fonction de production ayant deux facteurs de production X1 et X2. Par définition, on dira qu’une fonction de production est homogène de degré m si elle vérifie la condition suivante: ∀ 𝜆 > 1, 𝑌(𝜆𝑋1, 𝜆𝑋2 ) = 𝜆 𝑚𝑌(𝑋1,𝑋2) UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC Les rendements d’echeLLe Jusqu'ici, nous nous sommes intéressés à la sensibilité de la production à une variation de la quantité utilisée d'un facteur, quand tous les autres facteurs sont maintenus constants. On peut cependant être intéressé par les conséquences d'une variation simultanée de tous les facteurs. Par exemple, on peut s'interroger sur ce qu'adviendra de la production d'une usine de chaussures si on double les machines, le cuir, les bâtiments, la main-d’œuvre et tous les autres inputs ? Une telle question se réfère aux rendements d'échelle, c'est à dire aux conséquences de la variation de l'échelle de production. Les rendements d'échelle ont donc trait à la sensibilité de la production à une variation proportionnelle de tous les facteurs. Si l’on considère une fonction homogène, c’est-à-dire que ∀ 𝜆 > 1, 𝑌(𝜆𝑋1, 𝜆𝑋2 ) = 𝜆 𝑚𝑌(𝑋1, 𝑋2 ) Formellement, il est possible d'identifier les situations suivantes de rendements d'échelle : si m<1, les rendements sont décroissants à l’échelle (si vous augmentez les facteurs de production, la production diminue), si m = 1, les rendements sont dits constants à l’échelle (si vous doublez les quantités de facteurs employés, vous doublerez également la quantité produite). si m > 1, les rendements sont croissants à l’échelle (la production est plus que proportionnelle aux quantités de facteurs). L’analyse économique retient le plus souvent les fonctions de production à rendements constants à l’échelle. Tel est le cas, entre autres, de la fonction Cobb-Douglass. La fonction de production Cobb-Douglas a été inventée par un mathématicien et un économiste en 1928 pour représenter les conditions de production utilisant deux facteurs, le capital en quantité K et le travail en quantité L. Elle a pour forme : 𝑌 = 𝐴𝐾 𝛼𝐿 𝛽 , 𝑎𝑣𝑒𝑐 𝐴 > 0, 0 < 𝛼 < 1 𝑒𝑡 0 < 𝛽 < 1 𝛼 𝑒𝑡 𝛽 représentent respectivement la contribution du travail et du capital. Exercice 1 : Calculer les productivités moyennes et marginales, le TMST et étudier la nature des rendements d’échelle de la fonction Cobb-Douglas. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC La combinaison optimale des facteurs de production Pour produire, l’entrepreneur a besoin de facteurs de production. Etant donné qu’il se les procure à titre onéreux sur les marchés du travail et du capital, ils représentent pour lui des coûts. Ses ressources n’étant pas illimitées, il doit intégrer une contrainte dans ses prévisions. Cette contrainte a pour nom isocoût et englobe les diverses combinaisons (exprimées en valeur) de facteurs de production correspondant à une enveloppe de coûts donnée. Soit une entreprise utilise deux types de facteurs de production et C le coût de production. On note 𝐶 = 𝜔1𝑋1 + 𝜔2𝑋2 (1) 𝜔1 𝑒𝑠𝑡 𝑙𝑒 𝑝𝑟𝑖𝑥 𝑢𝑛𝑖𝑡𝑎𝑖𝑟𝑒 𝑑𝑢 𝑓𝑎𝑐𝑡𝑒𝑢𝑟 𝑑𝑒 𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛 1 𝑒𝑡 𝜔2 𝑒𝑠𝑡 𝑙𝑒 𝑝𝑟𝑖𝑥 𝑢𝑛𝑖𝑡𝑎𝑖𝑟𝑒 𝑑𝑢 𝑓𝑎𝑐𝑡𝑒𝑢𝑟 𝑑𝑒 𝑝𝑟𝑜𝑑𝑢𝑐𝑡𝑖𝑜𝑛 2 Souvent, on considère X2 comme facteur de production fixe et X1 comme le facteur de production variable. Lorsqu’on exprime X2 en fonction de X1 en utilisant l’équation (1), on obtient le sentier d’expansion ou l’isocoût. Par contre, en posant : 𝑇𝑀𝑆𝑇𝑋1/𝑋2 = 𝜔1 𝜔2 (2) On peut exprimer aussi X2 en fonction de X1. Dans ce cas, on parle l’eutope. L’équation (2) est appelé condition d’optimalité. Les équations de l’isocoût et de l’eutope permettent d’obtenir les conditions optimales (ou combinaison optimale). Exercice 2 : La fonction de production d’une entreprise s’écrit: 𝒀 = √𝑲 ∗ 𝑳 1. Montrer que cette fonction peut se mettre sous la forme de la fonction Cobb-Douglas. 2. Quelle est le degré d’homogénéité de cette fonction et interpréter. 3. Représenter les isoquantes pour Y=2 et Y=5 4. Présenter l’expression du taux marginal de substitution technique (T.M.S.T.). 5. Si le prix d’une unité de capital est 5 et celui de travail de 10, l’entreprise disposant d’un budget de 100 : a) Présenter les expressions du sentier d’expansion et de l’eutope. b) Rechercher la condition d’optimalité et la combinaison optimale de capital et de travail; c) Quel volume de production optimale l’entreprise peut-elle alors atteindre ? UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC CHAPITRE 4 Nous savons comment se comportent le consommateur et le producteur. Les deux étant rationnels, le consommateur achète un panier de bien qui maximise son utilité de manière optimale et le producteur vend son produit en quantité optimale. Chacun vient dans un marché pour atteindre son objectif. Le marché est le lieu de rencontre entre l’offre d’un bien matérialisée par les producteurs de ce bien et la demande matérialisée par les consommateurs qui demandent ce bien. Parmi les marchés qui existent, nous pouvons citer le marché concurrentiel ou marché en concurrence pure et parfaite. Les propriétés de ce marché sont : - L’atomicité du marché : Existence d’une multitude d’acheteurs et de producteurs, de taille comparable, de telle façon qu’aucun d’entre eux ne puisse influencer la détermination du prix du bien; - La fluidité du marché : existence d’une libre entrée et libre sortie du marché pour les agents (absence de barrière à l’entrée) - L’homogénéité du produit : des producteurs différents offrent sur le marché des produits strictement identiques. Le prix est alors la seule variable qui sera prise en compte par l’acheteur ; - La transparence du marché : les offreurs et les demandeurs disposent d’une information parfaite et gratuite sur les conditions du marché et notamment sur les prix des biens proposés par tous les producteurs; - La mobilité parfaite des facteurs de production qui doivent pouvoir, à tout moment, se déplacer du marché d’un bien à celui d’un autre bien. Lorsque l’une de ces propriétés n’est pas vérifiée dans un marché, ce dernier est appelé, marché en concurrence imparfaite. Dans le cas où il y a différenciation des produits et un grand nombre de producteurs, on parle de marché en concurrence monopolistique. L’hypothèse de l’homogénéité du produit caractéristique de la concurrence pure et parfaite est donc abandonnée. Dans ce modèle chaque firme offre un produit qui lui est spécifique, se trouvant ainsi en position de monopole. Les producteurs disposent alors d’une certaine latitude pour déterminer le prix et la quantité offerte puisque la différenciation du produit réduit l’élasticité de la demande en fidélisant les consommateurs. Le marché peut être en situation de monopsone (un seul acheteur et plusieurs producteurs), de monopole (un seul producteur et plusieurs acheteurs), de monopole bilatéral (un seul acheteur et un seul producteur), de duopole (deux offreurs et plusieurs acheteurs), d’oligopole (peu de vendeurs et beaucoup d’acheteurs) ou d’oligopsone (peu d’acheteurs et beaucoup de vendeurs). ÉQUILIBRE DU MARCHÉ ET DÉTERMINATION DU PRIX UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC La fonction demande La demande est l’ensemble de nécessité ou de besoins que l’on exprime pour obtenir un bien ou service. La demande est toujours exprimée par rapport à un bien ou un service, Elle se présente sous la forme d’une fonction inverse entre la quantité maximale demandée d’un bien et le prix de ce bien. C’est la loi de la demande. Si le prix d’un bien augmente, alors la quantité diminue et inversement. On distingue : - La demande individuelle : c’est une relation qui indique la quantité maximale du bien que le consommateur est prêt à acheter, pendant une période de temps, pour différentes valeurs possibles du prix du bien. - La demande globale d’un bien, appelée aussi demande du marché, est la somme des demandes individuelles de ce même bien. Dans le cas où les consommateurs ont la même fonction de demande individuelle, la demande globale est égale à leur effectif multiplié par la demande individuelle : 𝑫𝑮𝒍𝒐𝒃𝒂𝒍𝒆 = 𝒏 ∗ 𝑫𝒊𝒏𝒅𝒊𝒗𝒊𝒅𝒖𝒆𝒍𝒍𝒆, avec n=nombre de consommateurs. Dans le cas où les consommateurs ont des demandes individuelles différentes, la détermination de la demande globale se fait par la discussion en fonction du niveau du prix. Exemple : Soit deux consommateurs qui présentent chacun les fonctions de demandes suivantes : D1 = 5 – p et D2 = 15 – 5p La demande globale sera alors : 𝐷𝐺𝑙𝑜𝑏𝑎𝑙𝑒 = { 0 𝑠𝑖 𝑃 > 5 5 − 𝑃 𝑠𝑖 3 ≤ 𝑃 ≤ 5 20 − 6𝑃 𝑠𝑖 𝑃 < 3 - Déterminer la demande globale dans les cas suivants : P=1, P=4 ou P=10. - Représenter les courbes des trois demandes. La fonction offre La demande est l’ensemble de biens et services mis à la disposition (d’une clientèle) sur un marché à un prix donné. Elle se présente sous la forme d’une fonction croissante entre la quantité maximale offerte d’un bien et le prix de ce bien. C’est la loi de l’offre. UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC Si le prix d’un bien augmente, alors la quantité augmente et inversement. On distingue : - L’offre individuelle d’un bien: c’est une relation qui indique la quantité maximale du bien que le producteur est disposer à offrir, pendant une période de temps, pour différentes valeurs possibles du prix du bien. - L’offre globale d’un bien, appelée aussi offre du marché, est la somme des offres individuelles de ce même bien. Dans le cas où les producteurs ont la même fonction d’offre individuelle, l’offre globale est égale à leur effectif multiplié par la demande individuelle : 𝑶𝑮𝒍𝒐𝒃𝒂𝒍𝒆 = 𝒏 ∗ 𝑶𝒊𝒏𝒅𝒊𝒗𝒊𝒅𝒖𝒆𝒍𝒍𝒆, avec n=nombre de producteurs. Dans le cas où les producteurs ont des offres individuelles différentes, la détermination de l’offre globale se fait par la discussion en fonction du niveau du prix. Exemple : Soit deux producteurs qui présentent chacun les fonctions d’offres suivantes : O1 = 5P – 15 et O2 = P - 5 L’offre globale sera alors : 𝑂𝐺𝑙𝑜𝑏𝑎𝑙𝑒 = { 0 𝑠𝑖 𝑃 < 3 5𝑃 − 15 𝑠𝑖 3 ≤ 𝑃 ≤ 5 6𝑃 − 20 𝑠𝑖 𝑃 > 5 - Déterminer la demande globale dans les cas suivants : P=1, P=4 ou P=10. - Représenter les courbes des trois demandes. L’eqUiLibre dU marche L’équilibre du marché désigne l’équilibre qui résulte de la flexibilité des prix et correspond à une situation où, pour un niveau de prix (le prix d’équilibre), il y a égalité entre les quantités offertes (l’offre) et les quantités demandées (la demande). En concurrence pure et parfaite, cet équilibre est également un optimum qui maximise le surplus du consommateur et le surplus du producteur. Exemple : Soit un marché en situation de concurrence pure et parfaite sur lequel se vend un produit au prix P. La demande et l’offre globales sur ce marché sont : D= - 0,5P + 30 et O=2P-20. Déterminer le prix d’équilibre et les quantités optimales offerte et demandée. Représenter graphiquement les deux fonctions et calculer le surplus social (collectif). LA NOTION DE L’eLasticitÉ UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC L’élasticité est un indicateur de sensibilité : elle donne le sens et mesure l’intensité de la réaction d’une fonction à la variation de sa variable déterminante. Si on a la fonction 𝑦 = 𝑓(𝑥), l’élasticité de y par rapport à x est : 𝑒𝑦/𝑥 = 𝑑𝑦 𝑦 𝑑𝑥 𝑥 = 𝑑𝑦 𝑑𝑥 ∗ 𝑥 𝑦 Il peut y arriver que dans un marché, la demande du bien d’un consommateur puisse dépendre du prix de ce bien, du prix des autres biens et du revenu du consommateur. De ce fait : - L’élasticité de la demande d’un bien par rapport au revenu du consommateur est appelé élasticitérevenu et est notée 𝒆(𝑫𝒊/𝑹) ; - L’élasticité de la demande d’un bien par rapport au prix de ce bien est nommé élasticité-prix directe et est notée 𝒆(𝑫𝒊/𝑷𝒊 ) ; - L’élasticité de la demande d’un bien par rapport au prix d’un autre bien est nommée élasticité-prix croisée et est notée 𝒆(𝑫𝒊/𝑷𝒋 ) . A partir de ces résultats, on a le tableau suivant : Bien inférieur Bien supérieur Bien de luxe Bien normal et nécessaire Elasticité-revenu e < 0 e > 0 e > 1 0 < e ≤ 1 Biens complémentaires Biens indépendants Biens substituables Elasticité-prix croisée e < 0 e = 0 e > 0 Bien ordinaire ou bien typique Bien de Giffen ou bien atypique Elasticité-prix directe e < 0 e > 0 Demande rigide ou inélastique Demande élastique Elasticité-prix directe | e | < 1 | e | > 1 Exemple : Pour consommer du poisson, Jean doit faire le choix entre le consommer avec du manioc ou avec du pain. Cependant, il choisit d’acheter le pain. Or plusieurs études ont montré que la demande du pain dépend de son prix, du revenu du demandeur, du prix du poisson et du prix du manioc. Dans un marché quelconque, la demande du pain s’écrit de la manière suivante : 𝐷𝑝𝑎𝑖𝑛 = 10𝑅 2 20𝑃𝑝𝑎𝑖𝑛 + 5𝑃𝑝𝑜𝑖𝑠𝑠𝑜𝑛 − 2𝑃𝑚𝑎𝑛𝑖𝑜𝑐 UNIVERSITÉ LIBRE DU CONGO Cours de MICROÉCONOMIE BAHOUAYILA MILONGO Chancel Bardin ULC a) Quelle est la nature du pain dans ce marché (bien normal et de nécessité ou bien de luxe)? b) Le pain est-il un bien ordinaire dans ce marché ? c) La demande du pain est-elle rigide ou élastique ? d) Comment sont le manioc et le poisson par rapport au pain (substituable, complémentaire ou indépendant)?

Il ne s’agit pas de démontrer les théorèmes ou les résultats énoncés mais d’expliquer leurs utilisations et leurs règles de calcul. À la fin de chaque chapitre, de nombreux exercices corrigés, permettant aux étudiants de tester leurs connaissances, complètent et illustrent le cours.

Remarque 1.1.1 Une fonction peut avoir une limite quand x tend vers x0 sans qu’elle soit définie en x0. Remarque 1.1.2 Dire que x tend vers x0 c’est-à-dire que x s’approche de x0 sans jamais l’atteindre. Remarque 1.1.3 On définit la limite à droite et à gauche de f comme suit : 1. Limite à droite : lim x−→x0 x>x0 f (x) = l si ∀ > 0, ∃η > 0; ∀x ∈ R tels que 0 < x−x0 < η alors |f (x) − l| < , et on note lim x−→x + 0 f (x) = l. 1 Un voisinage d’un point x0 ∈ R est un intervalle ouvert qui contient ce point. ✐ ✐ “belhaj” — 2011/10/20 — 16:16 — page 4 — #10 ✐ ✐ ✐ ✐ ✐ ✐ 4 Chapitre 1. Les fonctions numériques d’une variable réelle 2. Limite à gauche : lim x−→x0 x 0, ∃η > 0; ∀x ∈ R tels que 0 < x0−x < η alors |f (x) − l| < , et on note lim x−→x − 0 f (x) = l. Proposition 1.1.1 La limite d’une fonction, lorsqu’elle existe, est unique. Preuve. Supposons que lim x−→x0 f (x) = l et lim x−→x0 f (x) = l 0 avec l 6= l 0 . Ainsi, ∀ > 0, ∃η > 0; ∀x ∈ R tels que |x − x0| < η alors |f (x) − l| <  et ∀ 0 > 0, ∃η 0 > 0; ∀x ∈ R tels que |x − x0| < η0 alors |f (x) − l 0 | < 0 . On a |l − l 0 | = |l − f (x) + f (x) − l 0 | ≤ |f (x) − l| | {z } < +|f (x) − l 0 | | {z } <0 . Alors, |l − l 0 | <  +  0 | {z }  00 . Pour  00 << 2 , on peut écrire |l − l 0 | < 00. Donc, l = l 0 . Ce qui est absurde. 1.1.1 Opérations sur les limites Supposons que lim x−→x0 f (x) = l1 et lim x−→x0 g (x) = l2 et soit λ ∈ R, alors on a : 1. lim x−→x0 (f + g) (x) = l1 + l2 2. lim x−→x0 (f × g) (x) = l1 × l2 3. lim x−→x0 |f (x)| = |l1| 4. lim x−→x0 (λf) (x) = λl1 5. lim x−→x0  f g  (x) = l1 l2 , (l2 6= 0) 6. Si f ≥ g au voisinage de x0 alors l1 ≥ l2. Exemple 1.1.1 Vérifier que lim x−→1 2 4x 2 − 1 2x − 1 = 2. En effet, il suffit de simplifier : 4x 2−1 2x−1 = (2x−1)(2x+1) 2x−1 = 2x + 1. 1.1.2 Formes indéterminées Les quatres formes indéterminées les plus connues sont : 0 0 , ∞ ∞ , ∞ − ∞, 0 × ∞.

En effet, multipliant q x + p x + √ x − √ x par son conjugué. On a r x + q x + √ x − √ x = q x + p x + √ x − √ x  q x + p x + √ x + √ x  q x + p x + √ x + √ x = x + p x + √ x − x q x + p x + √ x + √ x = p x + √ x q x + p x + √ x + √ x . Ensuite, mettant √ x en facteur : r x + q x + √ x − √ x = √ x q 1 + √ 1 x  √ x r 1 + q1 x + 1 x √ x + 1. Ainsi, quand x −→ +∞, q x + p x + √ x − √ x  −→ 1 2 . Exercice 1.1.1 Montrer que limx−→0 sin (3x) − 3 sin (x) tan (2x) − sin (2x) = −1. 1.2 Fonctions continues Soit f : Df x −→ 7−→ R f (x) et x0 ∈ R. Définition 1.2.1 On dit que f est continue en x0 ∈ R si : 1. f est définie en x0 (x0 ∈ Df), 2. lim x−→x0 f (x) = f (x0). Remarque 1.2.1 1. On dit que f est continue sur une partie A ⊆ Df si f est continue en tout point de A. 2. Soient f et g deux fonctions continues en x0 et soit λ un réel alors (f + g), (f × g), (λf), f g (g (x0) 6= 0) et |f| sont aussi continues en x0. ✐ ✐ “belhaj” — 2011/10/20 — 16:16 — page 6 — #12 ✐ ✐ ✐ ✐ ✐ ✐ 6 Chapitre 1. Les fonctions numériques d’une variable réelle Exemple 1.2.1 1. Étudier la continuité de la fonction f : R −→ R définie comme suit : f (x) =  0 si x = 0 sin 1 x si x 6= 0 2. Étudier la continuité de la fonction g : R −→ R définie comme suit : g (x) =  1 si x = 0 sin x x si x 6= 0 1.2.1 Propriétés des fonctions continues Théorème 1.2.1 Soit I = [a, b] , a < b, un intervalle fermé borné sur R. Toute fonction continue sur I est bornée et atteint ses bornes. Théorème 1.2.2 (des valeurs intermédiaires) Soit f : I−→ R continue sur I et soient a et b deux points de I tels que f (a) f (b) < 0. Alors, il existe c compris entre a et b tel que f (c) = 0. Exemple 1.2.2 Montrer que x 5 + x 3 + 1 = 0 admet une solution unique comprise entre −1 et 0. Théorème 1.2.3 L’image d’un intervalle de R par une fonction continue est un intervalle de R. Définition 1.2.2 (Prolongement par continuité) soit f : I−→ R une fonction et soit a /∈ I. Si f admet une limite l en a, alors la fonction fe: I ∪ {a} −→ R définie par fe(x) =  f (x) si x 6= a l si x = a est continue sur I ∪ {a} . Cette fonction est appelée prolongement de f par continuité en a. Exemple 1.2.3 Soit f (x) = sin x x . Puisque limx−→0 sin x x = 1. On peut vérifier que fe(x) =  f (x) si x 6= 0 1 si x = 0 est le prolongement par continuité de f en 0. 1.2.2 Théorème des fonctions réciproques Soit I un intervalle de R. Théorème 1.2.4 Toute fonction f : I−→ R, continue et strictement monotone admet une fonction réciproque, notée f −1 , qui est continue, strictement monotone et de même sens de variation que f. Remarque 1.2.2 Le graphe de f −1 s’obtient à partir de celui de f par la symétrie par rapport à la première bissectrice. ✐ ✐ “belhaj” — 2011/10/20 — 16:16 — page 7 — #13 ✐ ✐ ✐ ✐ ✐ ✐ 1.3 Dérivabilité 7 • Exemples de fonctions réciproques : Les fonctions Exponentielle et Logarithme Il existe une fonction notée e (ou exp) définie sur R comme suit : e : R x −→ 7−→ R e x continue et strictement croissante sur R avec e(R) = R ∗ +, donc il existe une fonction notée log telle que : log : ]0, +∞[ t −→ 7−→ R log (t) vérifiant log(e x ) = x ∀x ∈ R et exp(log(t)) = t, ∀t ∈ R ∗ +. Exercice 1.2.1 Étudier la continuité en 0 de la fonction f : R −→ R définie par : f (x) = sin 1 x  e 1 x + 1 si x 6= 0 et f (0) = 0. 1.3 Dérivabilité Soit f : Df ⊆ R −→ R une fonction continue en x0 ∈ Df. Définition 1.3.1 On dit que f est dérivable en x0 si et seulement si la fonction x 7−→ f (x) − f (x0) x − x0 admet une limite finie quand x tend vers x0. Lorsque cette limite existe et finie, elle sera notée f 0 (x0) et elle est appelée la dérivée de f en x0. 1.3.1 Opérations sur les fonctions dérivables Soit f : Df ⊆ R −→ R et g : Dg ⊆ R −→ R deux fonctions dérivables en x0 ∈ Df∩Dg, et soit λ ∈ R. Théorème 1.3.1 1. (f + g) est dérivable en x0 et on a (f + g) 0 (x0) = f 0 (x0) + g 0 (x0). 2. (λf) est dérivable en x0 et on a (λf) 0 (x0) = λf0 (x0). 3. (f ×g) est dérivable en x0 et on a (f ×g) 0 (x0) = f 0 (x0)×g(x0) + f(x0)×g 0 (x0). 4. Si g(x0) 6= 0, f g est dérivable en x0 et on a (f × g) 0 (x0) = f 0 (x0) × g(x0) − f(x0) × g 0 (x0) g 2 (x0) . 5. Si de plus f est dérivable en g(x0), alors (f ◦ g) est dérivable en x0 et on a : (f ◦ g) 0 (x0) = f 0 (g(x0)) × g 0 (x0).

Exemple 1.3.2 limx−→0 cos x−1 x = 0, pour f (x) = cos x − 1 et g (x) = x, on a f(0) = g(0) = 0 et g 0 (0) 6= 0.

Les fonctions numériques d’une variable réelle Exercice 1.6.1 La fonction de production d’une entreprise utilisant le travail "L" comme seul facteur de la production est donnée par f (x) = 1 2 √ x = production, notée p en économie. 1. Supposant qu’une entreprise utilise 900 unités pour produire 15 unités. Quelle sera l’augmentation de la production si l’entreprise décide d’utiliser une unité de travail supplémentaire. 2. On suppose que l’entreprise diminue l’effort du travail en passant de 900 à 891 unités. Donner une estimation de la variation de la production qui en résulte. Corrigé 1. On a ∆x = 1, x0 = 900. L’augmentation du produit est ∆f = f (901) − f (900) = 1 2 √ 901 − 1 2 √ 900 = 8.331 × 10−3 ' f 0 (900).∆x = 1 120 . 2.

Définition 1.6.6 (Notion d’élasticité) L’élasticité est un indicateur qui permet à un économiste ou gestionnaire d’évaluer l’effet d’une variation de ”x” (variable indépendant) sur une variable ”y” (dépendant) : y = f(x), variable endogène. Ainsi, l’élasticité de f par rapport à x au point x0 est donnée par ef/x (x0) = x0 f 0 (x0) f (x0) où f (x0) 6= 0. Exemple 1.6.5 f (x) = x 2 , x0 = 100 donc, ef/x (x0) = 100 × 2×100 1002 = 2. Remarque 1.6.1 L’élasticité ef/x donne une valeur approchée de la variation relative de f divisée par la variation relative de x : ef/x (x0) ' ∆f(x0) f(x0) ∆x x0 . En effet, f 0 (x0) ' f(x)−f(x0) x−x0 au voisinage V (x0) alors ef/x (x0) ' x0 ×  f (x) − f (x0) ∆x  × 1 f (x0) ' x0 ∆x × ∆f (x0) f (x0) . ✐ ✐ “belhaj” — 2011/10/20 — 16:16 — page 13 — #19 ✐ ✐ ✐ ✐ ✐ ✐ 1.7 Fonctions usuelles 13 Remarque 1.6.2 Si ef/x ' 0 alors la variation de x : ∆x à un effet négligeable sur la variation de f : ∆f.

Trouver la variation de la demande, puis la calculer numériquement. Corrigé 1. efQ/p = − 1 14 . 2.

Cette fonction est donc dérivable sur I = ]0; +∞[ et log0 (x) = 1 x , elle est donc strictement croissante sur I. Soit y > 0, la fonction f : x 7→ log (xy) et dérivable sur I et f 0 (x) = y 1 xy = 1 x , on en déduit que f (x) = log (x) + c où c est une constante, on a log (y) = f (1) = log (1) + c = c, par conséquent on obtient : Propriété 1.7.1 (fondamentale du logarithme) ∀x, y > 0, log (xy) = log (x) + log (y). ✐ ✐ “belhaj” — 2011/10/20 — 16:16 — page 14 — #20 ✐ ✐ ✐ ✐ ✐ ✐ 14 Chapitre 1.

Lorsque k = 0 la fonction f est nulle, lorsque k 6= 0, il existe un unique réel a > 0 différent de 1 tel que log (a) = 1 k , ce qui donne f (x) = log(x) log(a) .

La fonction exp est strictement croissante sur R et continue, de plus exp (0) = 1 et exp (1) = e. 2. La fonction log est dérivable sur ]0; +∞[ et sa dérivée ne s’annule pas, donc la fonction exp est dérivable sur R et exp0 (x) = 1 log0 (exp(x)) = exp (x). 3.

Troubleshooting Chapter 4 78 Chapter 4 System Check Procedures External Diskette Drive Check Do the following to isolate the problem to a controller, driver, or diskette. A write-enabled, diagnostic diskette is required. NOTE: Make sure that the diskette does not have more than one label attached to it. Multiple labels can cause damage to the drive or cause the drive to fail. Do the following to select the test device. 1. Boot from the diagnostics diskette and start the diagnostics program. 2. See if FDD Test is passed as the program runs to FDD Test. 3. Follow the instructions in the message window. If an error occurs with the internal diskette drive, reconnect the diskette connector on the system board. If the error still remains: 1. Reconnect the external diskette drive/DVD-ROM module. 2. Replace the external diskette drive/CD-ROM module. 3. Replace the main board. External Optical Disk Drive Check Do the following to isolate the problem to a controller, drive, or optical disk. Make sure that the optical disk does not have any label attached to it. The label can cause damage to the drive or can cause the drive to fail. Do the following to select the test device: 1. Boot from the diagnostics disc and start the diagnostics program. 2. See if CD-ROM Test is passed when the program runs to CD-ROM Test. 3. Follow the instructions in the message window. If an error occurs, reconnect the connector on the System board. If the error still remains: 1. Reconnect the optical disk drive module. 2. Replace the optical disk drive module. 3. Replace the main board. Keyboard or Auxiliary Input Device Check Remove the external keyboard if the internal keyboard is to be tested. If the internal keyboard does not work or an unexpected character appears, make sure that the flexible cable extending from the keyboard is correctly seated in the connector on the system board. If the keyboard cable connection is correct, run the Keyboard Test. If the tests detect a keyboard problem, do the following one at a time to correct the problem. Do not replace a non-defective FRU: 1. Reconnect the keyboard cables. 2. Replace the keyboard. 3. Replace the main board. The following auxiliary input devices are supported by this computer: q Numeric keypad Chapter 4 79 q External keyboard If any of these devices do not work, reconnect the cable connector and repeat the failing operation. Memory check Memory errors might stop system operations, show error messages on the screen, or hang the system. 1. Boot from the diagnostics diskette and start the diagnostic program (please refer to main board. 2. Go to the diagnostic memory in the test items. 3. Press F2 in the test items. 4. Follow the instructions in the message window. NOTE: Make sure that the DIMM is fully installed into the connector. A loose connection can cause an error. Power System Check To verify the symptom of the problem, power on the computer using each of the following power sources: 1. Remove the battery pack. 2. Connect the power adapter and check that power is supplied. 3. Disconnect the power adapter and install the charged battery pack; then check that power is supplied by the battery pack. If you suspect a power problem, see the appropriate power supply check in the following list: q “Check the Power Adapter” on page 79 q “Check the Battery Pack” on page 80 Check the Power Adapter Unplug the power adapter cable from the computer and measure the output voltage at the plug of the power adapter cable. See the following figure 1. If the voltage is not correct, replace the power adapter. 2. If the voltage is within the range, do the following: q Replace the System board. q If the problem is not corrected, see “Undetermined Problems” on page 90. q If the voltage is not correct, go to the next step. NOTE: An audible noise from the power adapter does not always indicate a defect. 3. If the power-on indicator does not light up, check the power cord of the power adapter for correct continuity and installation. 4. If the operational charge does not work, see “Check the Battery Pack” on page 80. Pin 1: +19 to +20.5V Pin 2: 0V, Ground 80 Chapter 4 Check the Battery Pack To check the battery pack, do the following: From Software: 1. Check out the Power Management in control Panel 2. In Power Meter, confirm that if the parameters shown in the screen for Current Power Source and Total Battery Power Remaining are correct. 3. Repeat the steps 1 and 2, for both battery and adapter. 4. This helps you identify first the problem is on recharging or discharging. From Hardware: 1. Power off the computer. 2. Remove the battery pack and measure the voltage between battery terminals 1(+) and 6(ground). 3. If the voltage is still less than 7.5 Vdc after recharging, replace the battery. To check the battery charge operation, use a discharged battery pack or a battery pack that has less than 50% of the total power remaining when installed in the computer. If the battery status indicator does not light up, remove the battery pack and let it return to room temperature. Re-install the battery pack. If the charge indicator still does not light up, replace the battery pack. If the charge indicator still does not light up, replace the DC/DC charger board. Touchpad Check If the touchpad doesn’t work, do the following actions one at a time to correct the problem. Do not replace a non-defective FRU: 1. Reconnect the touchpad cables. 2. Replace the touchpad. 3. Replace the system board. After you use the touchpad, the pointer drifts on the screen for a short time. This self-acting pointer movement can occur when a slight, steady pressure is applied to the touchpad pointer. This symptom is not a hardware problem. No service actions are necessary if the pointer movement stops in a short period of time. Chapter 4 81 Power-On Self-Test (POST) Error Messages The POST error message index lists the error message and their possible causes. The most likely cause is listed first. NOTE: Perform the FRU replacement or actions in the sequence shown in FRU/Action column, if the FRU replacement does not solve the problem, put the original part back in the computer. Do not replace a non-defective FRU. This index can also help you determine the next possible FRU to be replaced when servicing a computer. If the symptom is not listed, see “Undetermined Problems” on page 90. The following lists the error messages that the BIOS displays on the screen and the error symptoms classified by function. NOTE: Most of the error messages occur during POST. Some of them display information about a hardware device, e.g., the amount of memory installed. Others may indicate a problem with a device, such as the way it has been configured. NOTE: If the system fails after you make changes in the BIOS Setup Utility menus, reset the computer, enter Setup and install Setup defaults or correct the error. 82 Chapter 4 Post Code Table POST

FRU replacement should be considered only when a recurring problem exists. When analyzing an intermittent problem, do the following: 1. Run the advanced diagnostic test for the system board in loop mode at least 10 times. 2. If no error is detected, do not replace any FRU. 3. If any error is detected, replace the FRU. Rerun the test to verify that there are no more errors. 90 Chapter 4 Undetermined Problems The diagnostic problems does not identify which adapter or device failed, which installed devices are incorrect, whether a short circuit is suspected, or whether the system is inoperative. Follow these procedures to isolate the failing FRU (do not isolate non-defective FRU). NOTE: Verify that all attached devices are supported by the computer. NOTE: Verify that the power supply being used at the time of the failure is operating correctly. (See “Power System Check” on page 79.): 1. Power-off the computer. 2. Visually check them for damage. If any problems are found, replace the FRU. 3. Remove or disconnect all of the following devices: q Non-Acer devices q Printer, mouse, and other external devices q Battery pack q Hard disk drive q DIMM q CD-ROM/Diskette drive Module q PC Cards 4. Power-on the computer. 5. Determine if the problem has changed. 6. If the problem does not recur, reconnect the removed devices one at a time until you find the failing FRU. 7. If the problem remains, replace the following FRU one at a time.

There is one Hardware Open Gap on the main board for clearing the password check and one Hotkey for enabling BIOS Recovery. Clearing Password Check Hardware Open Gap Description HW Gap position on M/B space: Gap name is G61. Hardware Default Setting Operation Description Gap Open (Normal) Short (Clearing Password Check) G61 96 Chapter 5 Steps for Clearing BIOS Password Check If the user sets the BIOS Password (Supervisor Password and/or User Password) for a security reason, the BIOS will ask for the password during system POST or when the system enters into the BIOS Setup menu. If it is necessary to bypass the password check, the user needs to short the hardware gap to clear the password by following these steps: • Power off the system, and remove the HDD, AC adapter and battery from the computer. • Open the back cover of the computer and look for the hardware gap on the main board as shown in the picture(s) above. • Use an electric conductivity tool to short the two points of the hardware gap. • Plug in the AC adapter while retaining the short condition on the hardware gap. Press the power button to turn on the computer until the BIOS POST routine is finished. Finally, remove the tool from the hardware gap. • Restart the system. Press the F2 key to enter BIOS Setup menu. • If there is no password request, the BIOS Password is cleared. Otherwise, repeat the steps above and try again. NOTE: The steps are only for clearing the BIOS password (Supervisor Password and User Password). BIOS Recovery by Crisis Disk BIOS Recovery Boot Block BIOS Recovery Boot Block is a special block of the BIOS. It is used to boot up the system with minimum BIOS initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous BIOS flashing process failed. BIOS Recovery Hotkey The system provides a function hotkey: Fn+Esc, for enabling the BIOS Recovery process at system power-on during BIOS POST. To use this function, the AC adapter and the battery must be connected. If this function is enabled, the system will force the BIOS to enter a special BIOS block called Boot Block. Steps for BIOS Recovery by Crisis Disk Before doing this, prepare a Crisis Disk (refer to the “Steps for Creating the Crisis Disk in Windows XP/Vista” section below) and keep it ready in hand. Follow these steps for BIOS recovery: 1. Power off the system. 2. Connect a removable USB storage device containing the Crisis Disk to a USB port connected to the BIOS flash failed system. 3. Under power-off state, press and hold Fn+Esc and then press the power button. The system should be powered on with the Crisis BIOS Recovery process. 4. BIOS Boot Block starts to restore the BIOS code from the Crisis Disk to BIOS ROM on the failed system. 5. After the crisis flashing process is finished, the system will restart. After the Crisis Recovery process is finished, the system should have a successful and workable BIOS after power on. The user can then update the latest BIOS version for this system using the regular BIOS flashing process. Chapter 5 97 Creating the Crisis Disk in Windows XP/Vista Follow these steps to create the Crisis Disk: 1. Prepare a removable USB storage device (size greater than 10MB). Note that all data on the USB storage device will be cleared during the creation of the Crisis Disk. 2. Set up another computer loaded with Windows XP or Vista operating system. 3. Decompress the Crisis Package Source. Select WINCRIS.EXE and then select Run as administrator under Vista. 4. Keep the default settings and then click on the Start button. 5. When the pop-up warning dialog box appears, press OK to continue creating the Crisis Disk. 98 Chapter 5 6. The Crisis Disk will be created after a few seconds. 7. Press No if you do not want to create another Crisis Disk. 8. Reconnect the USB removable storage device and check if it contains the 3 files shown in the following figure.

produit Caractéristiques de la configuration standard Ses caractéristiques peuvent varier en fonction du modèle. Pour obtenir une liste complète du matériel et des logiciels installés sur l'ordinateur, exécutez l'utilitaire de diagnostic (uniquement fourni sur certains modèles d'ordinateurs). Figure 1-1 Configuration minitour convertible REMARQUE : La minitour convertible HP Compaq peut facilement être convertie en un ordinateur de bureau. Reportez-vous à la section Transformation de la minitour en ordinateur de bureau à la page 47 de ce manuel pour plus de détails. Figure 1-2 Configuration microtour FRWW Caractéristiques de la configuration standard 1 Figure 1-3 Configuration compact REMARQUE : L’ordinateur compact peut aussi être utilisé dans une orientation tour. Reportez-vous à la section Conversion de la configuration bureau en minitour à la page 100 de ce manuel pour plus de détails. Figure 1-4 Configuration d'ordinateur de bureau Ultra-Slim 2 Chapitre 1 Caractéristiques du produit FRWW Composants du panneau avant de la microtour convertible (CMT) La configuration des unités peut être différente selon le modèle. Certains modèles sont munis d’un cache protecteur qui recouvre un ou plusieurs compartiments d’unité. Figure 1-5 Éléments du panneau avant Tableau 1-1 Éléments du panneau avant 1 Unités optiques 5,25 pouces 5 Connecteur pour microphone/casque 2 Lecteur de cartes multimédia de 5,25 pouces (en option) 6 Voyant d’alimentation 3 Bouton d’alimentation double état 7 Connecteur de casque 4 Voyant d’activité du disque dur 8 Ports USB (Universal Serial Bus) ATTENTION : Le compartiment 5,25 pouces inférieur est moins profond que les deux compartiments supérieurs. Le compartiment inférieur peut recevoir une unité demi-hauteur ou tout autre périphérique dont la longueur ne dépasse pas 14,5 cm (5,7 pouces). Ne forcez pas une unité plus longue, comme une unité optique, dans le compartiment inférieur. Vous pourriez abîmer l’unité et la carte mère. Si vous forcez trop en mettant une unité de disque en place, vous risquez de l’endommager. REMARQUE : Lorsqu-un périphérique sera branché sur le connecteur Microphone/Casque, une boîte de dialogue apparaîtra et vous demandera si vous souhaitez utilisez le connecteur pour un périphérique d'entrée de ligne microphone ou un casque. Vous pouvez reconfigurer le connecteur à tout moment en double-cliquant sur l'icône Realtek HD Audio Manager de la barre des tâches Windows. REMARQUE : Le voyant d’alimentation est normalement vert lorsque l'ordinateur est sous tension. S’il clignote en rouge, un problème est survenu au niveau de l’ordinateur et un code de diagnostic est affiché. Reportez-vous au Guide de maintenance et d'entretien pour pouvoir interpréter le code.

Modules DIMM Les supports mémoire de la carte mère peuvent recevoir un maximum de quatre modules DIMM standard. À la livraison, ces connecteurs pour module mémoire accueillent au moins un module mémoire préinstallé. Pour exploiter entièrement la prise en charge de mémoire, vous pouvez équiper la carte mère d’un maximum de 16 Go de mémoire dans une configuration hautes performances à deux canaux. DDR3-SDRAM DIMM ATTENTION : Ce produit NE prend PAS en charge la mémoire DDR3 Ultra Low Voltage (tension ultra faible) (DDR3U). Le processeur n'est pas compatible avec la mémoire DDR3U et si vous branchez de la mémoire DDR3U sur la carte mère, cela peut endommager physiquement le module DIMM ou provoquer un dysfonctionnement du système. Pour que le système fonctionne correctement, les modules mémoire DDR3-SDRAM DIMM doivent être : ● standard à 240 broches ● sans tampon, non-ECC, conformes à la norme PC3-8500 DDR3-1066 MHz ou à la norme PC3-10600 DDR3-1333 MHz ● 1,5 volt DDR3-SDRAM DIMM Les modules mémoire DDR3-SDRAM DIMM doivent également : ● prendre en charge une latence CAS 7 DDR3 1066 MHz (rythme 7-7-7) et une latence CAS 9 DDR3 1333 MHz (rythme 9-9-9) ● contenir les informations obligatoires du JEDEC SPD De plus l’ordinateur doit prendre en charge : ● les technologies de mémoire non-ECC à 512 Mbits, 1 Gbit et 2 Gbits ● les modules DIMM à une face ou deux faces ● les modules DIMM construits avec des puces x8 et x16 DDR ; les puces x4 SDRAM ne sont pas prises en charge REMARQUE : Le système ne fonctionnera pas correctement si vous installez des modules DIMM non pris en charge. 24 Chapitre 2 Mises à niveau matérielles de la minitour convertible (CMT) FRWW Remplissage des supports DIMM La carte mère est équipée de quatre supports DIMM, deux par canal. Ceux-ci sont identifiés DIMM1, DIMM2, DIMM3 et DIMM4. Les sockets DIMM1 et DIMM2 fonctionnent sur le canal mémoire B. Les sockets DIMM3 et DIMM4 fonctionnent sur le canal mémoire A. Le système fonctionnera automatiquement en mode à un canal, à deux canaux ou flexible, en fonction de la position des modules DIMM. ● Le système fonctionne dans le mode à un canal si les modules DIMM sont installés dans les supports d’un même canal. ● Le système fonctionne en mode performant entrelacé à deux canaux si la capacité totale des modules DIMM du canal A est égale à celle des modules du canal B. Cependant, la technologie et la capacité des modules peuvent être différentes entre les deux canaux. Par exemple, si le canal A comporte deux modules DIMM de 1 Go et le canal B un module de 2 Go, le système fonctionnera en mode double canal. ● Le système fonctionne en mode flexible entrelacé si la capacité totale des modules DIMM du canal A n’est pas égale à celle des modules du canal B. En mode flexible, le canal doté de la quantité la plus faible de mémoire décrit la capacité totale de mémoire attribuée aux deux canaux et le reste est alloué à un canal unique. Pour obtenir une vitesse optimale, les canaux doivent être équilibrés afin que la quantité la plus élevée de mémoire soit répartie entre les deux canaux. Si un canal doit disposer de plus de mémoire que l’autre, la plus grande quantité doit être attribuée au canal A. Par exemple, si vous remplissez les supports avec un module DIMM de 2 Go et trois modules DIMM de 1 Go, le canal A devra être rempli avec le module DIMM de 2 Go et un module DIMM de 1 Go, tandis que le canal B devra être rempli avec les deux autres modules DIMM de 1 Go. Dans cette configuration, 4 Go sont exécutés en tant que double canal et 1 Go en tant que canal unique. ● Dans chaque mode, le module DIMM le plus lent du système détermine la vitesse maximum de fonctionnement. Installation de modules DIMM ATTENTION : Avant d'ajouter ou de retirer des modules mémoire, vous devez déconnecter le cordon d'alimentation et attendre environ 30 secondes pour éliminer toute énergie résiduelle. Quel que soit l'état de mise sous tension, une tension est toujours fournie aux modules mémoire tant que l'ordinateur est branché sur une prise secteur active. L'ajout ou le retrait de modules mémoire alors qu'une tension est toujours présente peut endommager de manière irrémédiable les modules mémoire ou la carte mère. Les supports des modules mémoire possèdent des contacts en or. Lors de la mise à niveau de la mémoire, il convient d’utiliser des modules DIMM avec des contacts en or, afin d’éviter les risques de corrosion et/ou d’oxydation pouvant résulter du contact de deux métaux incompatibles. L'électricité statique peut endommager les composants électroniques de l'ordinateur ou des cartes en option. Il est conseillé de toucher un objet métallique relié à la terre avant de commencer l'installation. Pour plus d'informations, reportez-vous à Décharges électrostatiques à la page 176. Lorsque vous manipulez un module mémoire, ne touchez aucun contact, car vous risqueriez d’endommager le module. 1. Retirez/désengagez tout périphérique de sécurité qui entrave l’ouverture de l’ordinateur. 2. Retirez tout support amovible de l’ordinateur, par exemple des CD ou des lecteurs flash USB. 3. Exécutez la procédure d’arrêt du système d’exploitation, puis mettez l’ordinateur et les périphériques externes hors tension. FRWW Installation de mémoire supplémentaire 25 4.

DIMM Les supports mémoire de la carte mère peuvent recevoir un maximum de quatre modules DIMM standard. À la livraison, ces connecteurs pour module mémoire accueillent au moins un DIMM préinstallé. Pour exploiter entièrement la prise en charge de mémoire, vous pouvez équiper la carte mère d'un maximum de 16 Go de mémoire dans une configuration hautes performances à deux canaux. DDR3-SDRAM DIMM ATTENTION : Ce produit NE prend PAS en charge la mémoire DDR3 Ultra Low Voltage (tension ultra faible) (DDR3U). Le processeur n'est pas compatible avec la mémoire DDR3U et si vous branchez de la mémoire DDR3U sur la carte mère, cela peut endommager physiquement le module DIMM ou provoquer un dysfonctionnement du système. Pour que le système fonctionne correctement, les modules mémoire DDR3-SDRAM DIMM doivent être : ● standard à 240 broches ● sans tampon, non-ECC, conformes à la norme PC3-8500 DDR3-1066 MHz ou à la norme PC3-10600 DDR3-1333 MHz ● 1,5 volt DDR3-SDRAM DIMM Les modules mémoire DDR3-SDRAM DIMM doivent également : ● prendre en charge une latence CAS 7 DDR3 1066 MHz (rythme 7-7-7) et une latence CAS 9 DDR3 1333 MHz (rythme 9-9-9) ● contenir les informations JEDEC SPD obligatoires En outre, l'ordinateur prend en charge : ● les technologies de mémoire non-ECC à 512 Mbits, 1 Gbit et 2 Gbits ● les modules DIMM monoface/double face. ● Modules DIMM conçus à partir de dispositifs DDR x8 et x16 ; Les modules DIMM conçus à partir de SDRAM x4 ne sont pas pris en charge REMARQUE : Le système ne fonctionnera pas correctement si vous installez des modules DIMM non pris en charge. FRWW Installation de mémoire supplémentaire 67 Remplissage des supports DIMM La carte mère est équipée de quatre supports DIMM, deux par canal. Ceux-ci sont identifiés DIMM1, DIMM2, DIMM3 et DIMM4. Les sockets DIMM1 et DIMM2 fonctionnent sur le canal mémoire B. Les sockets DIMM3 et DIMM4 fonctionnent sur le canal mémoire A. Le système fonctionnera automatiquement en mode canal unique, en mode double canal ou en mode flexible. Cela dépendra de l’installation des modules DIMM. ● Le système fonctionne en mode canal unique si les supports DIMM sont remplis dans un seul canal. ● Le système fonctionne en mode performant entrelacé à deux canaux si la capacité totale des modules DIMM du canal A est égale à celle des modules du canal B. Cependant, la technologie et la capacité des modules peuvent être différentes entre les deux canaux. Par exemple, si le canal A comporte deux modules DIMM de 1 Go et le canal B un module de 2 Go, le système fonctionnera en mode double canal. ● Le système fonctionnera en mode flexible si la capacité mémoire totale des modules DIMM du canal A n'est pas égale à la capacité mémoire totale des modules DIMM du canal B. En mode flexible, le canal occupé par le moins de mémoire représente la mémoire totale attribuée au double canal et la mémoire restante est attribuée au canal unique. Pour obtenir une vitesse optimale, les canaux doivent être équilibrés afin que la quantité la plus élevée de mémoire soit répartie entre les deux canaux. Si un canal dispose de plus de mémoire que l'autre, la plus grande capacité doit être attribuée au canal A. Par exemple, si vous occupez les sockets avec un module DIMM 2 Go et avec trois modules DIMM 1 Go, le canal A devra être occupé par le module DIMM 2 Go et par un module DIMM 1 Go. Le canal B devra être occupé par les deux autres modules DIMM 1 Go. Dans cette configuration, 4 Go sont exécutés en tant que double canal et 1 Go en tant que canal unique. ● Quel que soit le mode, la vitesse de fonctionnement maximale est déterminée par le module DIMM le plus lent du système. Installation des modules DIMM ATTENTION : Avant d'ajouter ou de retirer des modules mémoire, vous devez déconnecter le cordon d'alimentation et attendre environ 30 secondes pour éliminer toute énergie résiduelle. Quel que soit l'état de mise sous tension, une tension est toujours fournie aux modules mémoire tant que l'ordinateur est branché sur une prise secteur active. L'ajout ou le retrait de modules mémoire alors qu'une tension est toujours présente peut endommager de manière irrémédiable les modules mémoire ou la carte mère. Les supports de modules mémoire ont des contacts en métal doré. Lorsque vous mettez à niveau la mémoire, il est important d'utiliser des modules mémoire avec des contacts en métal doré pour éviter la corrosion et/ou l'oxydation due à l'incompatibilité des métaux en contact les uns avec les autres. L'électricité statique peut endommager les composants électroniques de l'ordinateur ou des cartes en option. Il est conseillé de toucher un objet métallique relié à la terre avant de commencer l'installation. Pour plus d'informations, reportez-vous à Décharges électrostatiques à la page 176. Lorsque vous manipulez un module de mémoire, ne touchez aucun contact, vous risqueriez d'endommager le module. 1. Retirez/dégagez tout périphérique de sécurité qui gêne l'ouverture de l'ordinateur. 2. Retirez tout support amovible de l'ordinateur, par exemple des CD ou des lecteurs flash USB. 3. Mettez l'ordinateur hors tension sans risque via le système d'exploitation, puis mettez les périphériques externes hors tension. 68 Chapitre 3 Mises à niveau matérielles de la microtour (MT) FRWW 4. Débranchez le cordon d'alimentation de la prise électrique, puis débranchez tout périphérique externe. ATTENTION : Avant d'ajouter ou de retirer des modules mémoire, vous devez déconnecter le cordon d'alimentation et attendre environ 30 secondes pour éliminer toute énergie résiduelle.

DIMM Les supports mémoire de la carte mère peuvent recevoir un maximum de quatre modules DIMM standard. À la livraison, ces connecteurs pour module mémoire accueillent au moins un DIMM préinstallé. Pour exploiter entièrement la prise en charge de mémoire, vous pouvez équiper la carte mère d'un maximum de 16 Go de mémoire dans une configuration hautes performances à deux canaux. DDR3-SDRAM DIMM ATTENTION : Ce produit NE prend PAS en charge la mémoire DDR3 Ultra Low Voltage (tension ultra faible) (DDR3U). Le processeur n'est pas compatible avec la mémoire DDR3U et si vous branchez de la mémoire DDR3U sur la carte mère, cela peut endommager physiquement le module DIMM ou provoquer un dysfonctionnement du système. Pour que le système fonctionne correctement, les modules mémoire DDR3-SDRAM DIMM doivent être : ● standard à 240 broches ● sans tampon, non-ECC, conformes à la norme PC3-8500 DDR3-1066 MHz ou à la norme PC3-10600 DDR3-1333 MHz ● 1,5 volt DDR3-SDRAM DIMM Les modules mémoire DDR3-SDRAM DIMM doivent également : ● prendre en charge une latence CAS 7 DDR3 1066 MHz (rythme 7-7-7) et une latence CAS 9 DDR3 1333 MHz (rythme 9-9-9) ● contenir les informations JEDEC SPD obligatoires En outre, l'ordinateur prend en charge : ● les technologies de mémoire non-ECC à 512 Mbits, 1 Gbit et 2 Gbits ● les modules DIMM monoface/double face. ● Modules DIMM conçus à partir de dispositifs DDR x8 et x16 ; Les modules DIMM conçus à partir de SDRAM x4 ne sont pas pris en charge REMARQUE : Le système ne fonctionnera pas correctement si vous installez des modules DIMM non pris en charge. FRWW Installation de mémoire supplémentaire 105 Remplissage des supports DIMM La carte mère est équipée de quatre supports DIMM, deux par canal. Ceux-ci sont identifiés DIMM1, DIMM2, DIMM3 et DIMM4. Les sockets DIMM1 et DIMM2 fonctionnent sur le canal mémoire B. Les sockets DIMM3 et DIMM4 fonctionnent sur le canal mémoire A. Le système fonctionnera automatiquement en mode canal unique, en mode double canal ou en mode flexible. Cela dépendra de l’installation des modules DIMM. ● Le système fonctionne en mode canal unique si les supports DIMM sont remplis dans un seul canal. ● Le système fonctionne en mode performant entrelacé à deux canaux si la capacité totale des modules DIMM du canal A est égale à celle des modules du canal B. Cependant, la technologie et la capacité des modules peuvent être différentes entre les deux canaux. Par exemple, si le canal A comporte deux modules DIMM de 1 Go et le canal B un module de 2 Go, le système fonctionnera en mode double canal. ● Le système fonctionnera en mode flexible si la capacité mémoire totale des modules DIMM du canal A n'est pas égale à la capacité mémoire totale des modules DIMM du canal B. En mode flexible, le canal occupé par le moins de mémoire représente la mémoire totale attribuée au double canal et la mémoire restante est attribuée au canal unique. Pour obtenir une vitesse optimale, les canaux doivent être équilibrés afin que la quantité la plus élevée de mémoire soit répartie entre les deux canaux. Si un canal dispose de plus de mémoire que l'autre, la plus grande capacité doit être attribuée au canal A. Par exemple, si vous occupez les sockets avec un module DIMM 2 Go et avec trois modules DIMM 1 Go, le canal A devra être occupé par le module DIMM 2 Go et par un module DIMM 1 Go. Le canal B devra être occupé par les deux autres modules DIMM 1 Go. Dans cette configuration, 4 Go sont exécutés en tant que double canal et 1 Go en tant que canal unique. ● Quel que soit le mode, la vitesse de fonctionnement maximale est déterminée par le module DIMM le plus lent du système. Installation des modules DIMM ATTENTION : Avant d'ajouter ou de retirer des modules mémoire, vous devez déconnecter le cordon d'alimentation et attendre environ 30 secondes pour éliminer toute énergie résiduelle. Quel que soit l'état de mise sous tension, une tension est toujours fournie aux modules mémoire tant que l'ordinateur est branché sur une prise secteur active. L'ajout ou le retrait de modules mémoire alors qu'une tension est toujours présente peut endommager de manière irrémédiable les modules mémoire ou la carte mère. Les supports de modules mémoire ont des contacts en métal doré. Lorsque vous mettez à niveau la mémoire, il est important d'utiliser des modules mémoire avec des contacts en métal doré pour éviter la corrosion et/ou l'oxydation due à l'incompatibilité des métaux en contact les uns avec les autres. L'électricité statique peut endommager les composants électroniques de l'ordinateur ou des cartes en option. Il est conseillé de toucher un objet métallique relié à la terre avant de commencer l'installation. Pour plus d'informations, reportez-vous à Décharges électrostatiques à la page 176. Lorsque vous manipulez un module de mémoire, ne touchez aucun contact, vous risqueriez d'endommager le module. 1.

Ce type de dégât peut diminuer la durée de vie du dispositif. Prévention des décharges électrostatiques Afin d’éviter tout risque de dégât par l’électricité statique, prenez les précautions suivantes : ● Évitez tout contact avec les mains, en transportant et en rangeant les produits dans des emballages antistatiques. ● Laissez les éléments sensibles à l’électricité statique dans leur emballage jusqu’au moment de l’installation. ● Placez les éléments sur une surface mise à la terre, avant de les retirer de leur emballage. ● Évitez de toucher les broches, les conducteurs et les circuits. ● Veillez à toujours être relié à la terre lorsque vous touchez un élément ou un assemblage sensible à l’électricité statique. Méthodes de mise à la terre Il en existe plusieurs. Prenez au moins l’une des précautions suivantes lorsque vous installez ou manipulez des éléments sensibles à l’électricité statique : ● Utilisez un bracelet électrostatique relié par un cordon de terre au châssis de l’ordinateur ou à une station de travail. Les bracelets électrostatiques sont des bracelets flexibles dont les cordons ont une résistance d’au moins 1 mégohm +/- 10 %. Pour une mise à la terre optimale, veillez à maintenir le bracelet serré contre la peau. ● Utilisez les autres types de bracelets antistatiques disponibles lorsque vous travaillez debout. Portez-les à chaque pied lorsque vous vous trouvez sur des sols ou des tapis conducteurs. ● Utilisez des outils d’entretien conducteurs. ● Utilisez un kit de réparation équipé d’un tapis antistatique. Si vous ne disposez d’aucun des équipements suggérés pour une mise à la terre correcte, contactez votre revendeur ou fournisseur de services agréé HP. REMARQUE : Pour plus d’informations sur l’électricité statique, adressez-vous à votre revendeur ou fournisseur de services agréé HP. 176 Annexe D Décharges électrostatiques FRWW E Utilisation, entretien courant et préparation au transport Utilisation et entretien courant de l’ordinateur Les instructions suivantes doivent être suivies pour installer et entretenir convenablement l’ordinateur et son moniteur : ● Protégez l’ordinateur de l’humidité, des rayons du soleil et des températures extrêmes. ● Faites fonctionner l’ordinateur sur une surface stable et plane. Laissez un espace libre d’au moins 10 cm tout autour des côtés ventilés de l’ordinateur et au-dessus du moniteur afin d’assurer une bonne aération. ● Ne réduisez jamais l’aération en bloquant les orifices d’aération ou les entrées d’air. Ne placez pas le clavier - pieds repliés - directement contre l’avant de l’ordinateur de bureau, car cela gêne également la circulation de l’air. ● Ne faites jamais fonctionner l’ordinateur lorsque le panneau d’accès ou l’un des caches de connecteur de carte d’extension est ouvert. ● N’empilez pas les ordinateurs l’un sur l’autre ou ne les placez pas l’un à côté de l’autre pour éviter de faire recirculer l’air chaud qu’ils évacuent. ● Si l’ordinateur doit être utilisé dans un boîtier séparé, celui-ci doit être pourvu d’orifices d’aération (aspiration et refoulement) ; les autres instructions d’utilisation énoncées ci-dessus restent d’application. ● Ne laissez pas de liquides à proximité de l’ordinateur ou du clavier. ● N’obstruez jamais les grilles d’aération du moniteur (n’y déposez aucun objet). ● Installez ou activez les fonctions d’économie d’énergie du système d’exploitation ou d’un autre logiciel, y compris les états de veille. ● Mettez l’ordinateur hors tension avant d’effectuer l’une des opérations suivantes : ◦ Essuyez l’extérieur de l’ordinateur avec un chiffon doux humide. Les produits d’entretien pourraient ternir ou abímer la finition de l’ordinateur. ◦ Nettoyez de temps à autre toutes les entrées d’air de l’ordinateur. Les poussières, les matières pelucheuses et autres corps étrangers peuvent obstruer les entrées et réduire l’aération. FRWW Utilisation et entretien courant de l’ordinateur 177 Précautions relatives à l’unité optique Assurez-vous de respecter les recommandations suivantes lorsque vous utilisez ou nettoyez l’unité optique. Procédure ● Ne déplacez pas l’unité pendant son fonctionnement car vous risqueriez de provoquer une erreur de lecture. ● N’exposez pas l’unité à des changements subits de température. Il pourrait se former de la condensation à l’intérieur de l’unité. En cas de changement brutal de la température en cours d’utilisation de l’unité, attendez au moins une heure avant de mettre l’équipement hors tension. Si vous l’utilisiez immédiatement, des erreurs de lecture pourraient se produire. ● Évitez de placer l’unité dans un environnement soumis à une forte humidité, à des températures extrêmes, à des vibrations mécaniques ou aux rayons du soleil. Nettoyage ● Nettoyez le panneau et les boutons avec un chiffon doux et sec ou légèrement humecté d’un produit détergent doux. Ne vaporisez jamais de liquides nettoyants directement sur l’unité. ● N’employez pas de dissolvants, comme l’alcool ou l’essence, qui risqueraient d’abímer la surface. Sécurité Si un objet ou un liquide pénètre dans l’unité, débranchez immédiatement l’ordinateur et faites-le contrôler par un fournisseur de services agréé HP. Préparation au transport Pour préparer l’ordinateur en vue de son transport, suivez les recommandations suivantes : 1. Sauvegardez les fichiers du disque dur sur des disques PD, des cartouches de bande, des CD ou des lecteurs flash USB. Assurez-vous que le support de sauvegarde n’est pas exposé à des impulsions électriques ou magnétiques pendant qu’il est stocké ou en transit. REMARQUE : Le disque dur se verrouille automatiquement lorsque le système est mis hors tension. 2. Retirez et stockez tous les supports amovibles. 3. Éteignez l’ordinateur et les périphériques externes. 4. Débranchez le cordon d’alimentation de la prise secteur, puis de l’ordinateur. 5. Débranchez les composants du système et les périphériques externes de leur source d’alimentation, puis de l’ordinateur. REMARQUE : Assurez-vous que toutes les cartes sont correctement fixées et verrouillées dans leurs connecteurs avant d’expédier l’ordinateur. 6. Emballez les composants du système ainsi que les périphériques externes dans leur emballage d’origine ou dans un emballage similaire suffisamment protégé. 178 Annexe E Utilisation, entretien courant et préparation au transport FRWW Index A alimentation Branchement du câble à l'USDT 138 C cache de carte d'extension Retrait du CMT 28 Retrait du MT 71 Retrait du SFF 110 carte d'extension Installation du CMT 27 Installation du MT 70 Installation du SFF 109 Retrait du CMT 27 Retrait du MT 70 Retrait du SFF 109 clavier éléments 12 touche de logo Windows 13 clé FailSafe 173 connexions d'unité de carte mère CMT 22 MT 64 SFF 101 USDT 144 conversion de la tour CMT 49 USDT 100, 143 conversion en ordinateur de bureau CMT 47 couvercle des ports Installation de l'USDT 155 D déverrouillage du panneau d’accès 173 directives d'installation 95 disque dur Installation de l'USDT 152 Installation du CMT 42 Installation du MT 84 Installation du SFF 126 Retrait du CMT 32 Retrait du MT 82 Retrait du SFF 126 Retrait du USDT 152 E électricité statique, prévention 176 éléments de la face arrière CMT 7 MT 8 SFF 9 USDT 10 éléments du panneau avant CMT 3 MT 4 SFF 5 USDT 6 emplacements de l'ID du produit 14 emplacements du numéro de série 14 I installation Câbles des lecteurs du CMT 36 câbles du lecteur du MT 75 Câbles du lecteur SFF 114 carte d'extension CMT 27 carte d'extension MT 70 carte d'extension SFF 109 Couvercle de port USDT 155 Disque dur CMT 42 Disque dur MT 84 Disque dur SFF 126 Disque dur USDT 152 lecteur de cartes multimédia du MT 79 lecteur de cartes multimédia du SFF 122 lecteur de cartes multimédias du CMT 38 Lecteur optique CMT 38 Lecteur optique MT 79 Lecteur optique SFF 118 Lecteur optique USDT 151 Mémoire du CMT 24 Mémoire du MT 67 Mémoire SFF 105 Mémoire USDT 145 pile 165 instructions d’aération 177 instructions pour l’installation 17, 59, 137 L lecteur de cartes multimédia caractéristiques 11 Installation du MT 79 Installation du SFF 122 Retrait du MT 77 Retrait du SFF 121 lecteur de cartes multimédias Installation du CMT 38 Retrait du CMT 32 lecteur optique Fixation du loquet de dégagement de l'USDT 150 Installation de l'USDT 151 Installation du CMT 38 Installation du SFF 118 Installation MT 79 Retrait du CMT 32 Retrait du MT 77 Retrait du SFF 116 Retrait du USDT 149 lecteurs branchements de câbles du MT 75 Branchements des câbles du CMT 36 branchements des câbles du SFF 114 Emplacements sous CMT 31 Emplacements sous MT 74 Emplacements sous SFF 113 Installation du CMT 36 Installation du MT 75 Installation du SFF 114 FRWW Index 179 M mémoire Installation de l'USDT 145 Installation du CMT 24 Installation du MT 67 Installation du SFF 105 Occupation des sockets du MT 68 Occupation du socket de l'USDT 146 Occupation du socket du CMT 25 Occupation du socket du SFF 106 Spécifications du CMT 24 Spécifications du MT 67 Spécifications SFF 105 Spécifications USDT 145 Modules de mémoire DIMM.

Modules DIMM Les supports mémoire de la carte mère peuvent recevoir un maximum de quatre modules DIMM standard. À la livraison, ces connecteurs pour module mémoire accueillent au moins un module mémoire préinstallé. Pour exploiter entièrement la prise en charge de mémoire, vous pouvez équiper la carte mère d’un maximum de 16 Go de mémoire dans une configuration hautes performances à deux canaux. DDR3-SDRAM DIMM ATTENTION : Ce produit NE prend PAS en charge la mémoire DDR3 Ultra Low Voltage (tension ultra faible) (DDR3U). Le processeur n'est pas compatible avec la mémoire DDR3U et si vous branchez de la mémoire DDR3U sur la carte mère, cela peut endommager physiquement le module DIMM ou provoquer un dysfonctionnement du système. Pour que le système fonctionne correctement, les modules mémoire DDR3-SDRAM DIMM doivent être : ● standard à 240 broches ● sans tampon, non-ECC PC3-12800 DDR3-1600 MHz ● 1,5 volt DDR3-SDRAM DIMM Les modules mémoire DDR3-SDRAM DIMM doivent également : ● prendre en charge une latence CAS 11 DDR3 1600 MHz (synchronisation 11-11-11) ● contenir les informations obligatoires du JEDEC SPD De plus l’ordinateur doit prendre en charge : ● les technologies de mémoire non-ECC à 512 Mbits, 1 Gbit et 2 Gbits ● les modules DIMM à une face ou deux faces ● les modules DIMM construits avec des puces x8 et x16 DDR ; les puces x4 SDRAM ne sont pas prises en charge REMARQUE : Le système ne fonctionnera pas correctement si vous installez des modules DIMM non pris en charge. 24 Chapitre 2 Mises à niveau matérielles de la minitour convertible (CMT) Remplissage des supports DIMM La carte mère est équipée de quatre supports DIMM, deux par canal. Ceux-ci sont identifiés DIMM1, DIMM2, DIMM3 et DIMM4. Les sockets DIMM1 et DIMM2 fonctionnent sur le canal mémoire B. Les sockets DIMM3 et DIMM4 fonctionnent sur le canal mémoire A. Le système fonctionnera automatiquement en mode à un canal, à deux canaux ou flexible, en fonction de la position des modules DIMM. ● Le système fonctionne dans le mode à un canal si les modules DIMM sont installés dans les supports d’un même canal. ● Le système fonctionne en mode performant entrelacé à deux canaux si la capacité totale des modules DIMM du canal A est égale à celle des modules du canal B. Cependant, la technologie et la capacité des modules peuvent être différentes entre les deux canaux. Par exemple, si le canal A comporte deux modules DIMM de 1 Go et le canal B un module de 2 Go, le système fonctionnera en mode double canal. ● Le système fonctionne en mode flexible entrelacé si la capacité totale des modules DIMM du canal A n’est pas égale à celle des modules du canal B. En mode flexible, le canal doté de la quantité la plus faible de mémoire décrit la capacité totale de mémoire attribuée aux deux canaux et le reste est alloué à un canal unique. Pour obtenir une vitesse optimale, les canaux doivent être équilibrés afin que la quantité la plus élevée de mémoire soit répartie entre les deux canaux. Si un canal doit disposer de plus de mémoire que l’autre, la plus grande quantité doit être attribuée au canal A. Par exemple, si vous remplissez les supports avec un module DIMM de 2 Go et trois modules DIMM de 1 Go, le canal A devra être rempli avec le module DIMM de 2 Go et un module DIMM de 1 Go, tandis que le canal B devra être rempli avec les deux autres modules DIMM de 1 Go. Dans cette configuration, 4 Go sont exécutés en tant que double canal et 1 Go en tant que canal unique. ● Dans chaque mode, le module DIMM le plus lent du système détermine la vitesse maximum de fonctionnement. Installation de modules DIMM ATTENTION : Avant d'ajouter ou de retirer des modules mémoire, vous devez déconnecter le cordon d'alimentation et attendre environ 30 secondes pour éliminer toute énergie résiduelle. Quel que soit l'état de mise sous tension, une tension est toujours fournie aux modules mémoire tant que l'ordinateur est branché sur une prise secteur active. L'ajout ou le retrait de modules mémoire alors qu'une tension est toujours présente peut endommager de manière irrémédiable les modules mémoire ou la carte mère. Les supports des modules mémoire possèdent des contacts en or. Lors de la mise à niveau de la mémoire, il convient d’utiliser des modules DIMM avec des contacts en or, afin d’éviter les risques de corrosion et/ou d’oxydation pouvant résulter du contact de deux métaux incompatibles. L'électricité statique peut endommager les composants électroniques de l'ordinateur ou des cartes en option. Il est conseillé de toucher un objet métallique relié à la terre avant de commencer l'installation. Pour plus d'informations, reportez-vous à Décharges électrostatiques à la page 173. Lorsque vous manipulez un module mémoire, ne touchez aucun contact, car vous risqueriez d’endommager le module. 1. Retirez/désengagez tout périphérique de sécurité qui entrave l’ouverture de l’ordinateur. 2. Retirez tout support amovible de l’ordinateur, par exemple des CD ou des lecteurs flash USB. 3. Exécutez la procédure d’arrêt du système d’exploitation, puis mettez l’ordinateur et les périphériques externes hors tension. Installation de mémoire supplémentaire 25 4.

DIMM Les supports mémoire de la carte mère peuvent recevoir un maximum de quatre modules DIMM standard. À la livraison, ces connecteurs pour module mémoire accueillent au moins un DIMM préinstallé. Pour exploiter entièrement la prise en charge de mémoire, vous pouvez équiper la carte mère d'un maximum de 16 Go de mémoire dans une configuration hautes performances à deux canaux. DDR3-SDRAM DIMM ATTENTION : Ce produit NE prend PAS en charge la mémoire DDR3 Ultra Low Voltage (tension ultra faible) (DDR3U). Le processeur n'est pas compatible avec la mémoire DDR3U et si vous branchez de la mémoire DDR3U sur la carte mère, cela peut endommager physiquement le module DIMM ou provoquer un dysfonctionnement du système. Pour que le système fonctionne correctement, les modules mémoire DDR3-SDRAM DIMM doivent être : ● standard à 240 broches ● sans tampon, non-ECC PC3-12800 DDR3-1600 MHz ● 1,5 volt DDR3-SDRAM DIMM Les modules mémoire DDR3-SDRAM DIMM doivent également : ● prendre en charge une latence CAS 11 DDR3 1600 MHz (synchronisation 11-11-11) ● contenir les informations JEDEC SPD obligatoires En outre, l'ordinateur prend en charge : ● les technologies de mémoire non-ECC à 512 Mbits, 1 Gbit et 2 Gbits ● les modules DIMM monoface/double face. ● Modules DIMM conçus à partir de dispositifs DDR x8 et x16 ; Les modules DIMM conçus à partir de SDRAM x4 ne sont pas pris en charge REMARQUE : Le système ne fonctionnera pas correctement si vous installez des modules DIMM non pris en charge. 66 Chapitre 3 Mises à niveau matérielles de la microtour (MT) Remplissage des supports DIMM La carte mère est équipée de quatre supports DIMM, deux par canal. Ceux-ci sont identifiés DIMM1, DIMM2, DIMM3 et DIMM4. Les sockets DIMM1 et DIMM2 fonctionnent sur le canal mémoire B. Les sockets DIMM3 et DIMM4 fonctionnent sur le canal mémoire A. Le système fonctionnera automatiquement en mode canal unique, en mode double canal ou en mode flexible. Cela dépendra de l’installation des modules DIMM. ● Le système fonctionne en mode canal unique si les supports DIMM sont remplis dans un seul canal. ● Le système fonctionne en mode performant entrelacé à deux canaux si la capacité totale des modules DIMM du canal A est égale à celle des modules du canal B. Cependant, la technologie et la capacité des modules peuvent être différentes entre les deux canaux. Par exemple, si le canal A comporte deux modules DIMM de 1 Go et le canal B un module de 2 Go, le système fonctionnera en mode double canal. ● Le système fonctionnera en mode flexible si la capacité mémoire totale des modules DIMM du canal A n'est pas égale à la capacité mémoire totale des modules DIMM du canal B. En mode flexible, le canal occupé par le moins de mémoire représente la mémoire totale attribuée au double canal et la mémoire restante est attribuée au canal unique. Pour obtenir une vitesse optimale, les canaux doivent être équilibrés afin que la quantité la plus élevée de mémoire soit répartie entre les deux canaux. Si un canal dispose de plus de mémoire que l'autre, la plus grande capacité doit être attribuée au canal A. Par exemple, si vous occupez les sockets avec un module DIMM 2 Go et avec trois modules DIMM 1 Go, le canal A devra être occupé par le module DIMM 2 Go et par un module DIMM 1 Go. Le canal B devra être occupé par les deux autres modules DIMM 1 Go. Dans cette configuration, 4 Go sont exécutés en tant que double canal et 1 Go en tant que canal unique. ● Quel que soit le mode, la vitesse de fonctionnement maximale est déterminée par le module DIMM le plus lent du système. Installation des modules DIMM ATTENTION : Avant d'ajouter ou de retirer des modules mémoire, vous devez déconnecter le cordon d'alimentation et attendre environ 30 secondes pour éliminer toute énergie résiduelle. Quel que soit l'état de mise sous tension, une tension est toujours fournie aux modules mémoire tant que l'ordinateur est branché sur une prise secteur active. L'ajout ou le retrait de modules mémoire alors qu'une tension est toujours présente peut endommager de manière irrémédiable les modules mémoire ou la carte mère. Les supports de modules mémoire ont des contacts en métal doré. Lorsque vous mettez à niveau la mémoire, il est important d'utiliser des modules mémoire avec des contacts en métal doré pour éviter la corrosion et/ou l'oxydation due à l'incompatibilité des métaux en contact les uns avec les autres. L'électricité statique peut endommager les composants électroniques de l'ordinateur ou des cartes en option. Il est conseillé de toucher un objet métallique relié à la terre avant de commencer l'installation. Pour plus d'informations, reportez-vous à Décharges électrostatiques à la page 173.

DIMM Les supports mémoire de la carte mère peuvent recevoir un maximum de quatre modules DIMM standard. À la livraison, ces connecteurs pour module mémoire accueillent au moins un DIMM préinstallé. Pour exploiter entièrement la prise en charge de mémoire, vous pouvez équiper la carte mère d'un maximum de 16 Go de mémoire dans une configuration hautes performances à deux canaux. DDR3-SDRAM DIMM ATTENTION : Ce produit NE prend PAS en charge la mémoire DDR3 Ultra Low Voltage (tension ultra faible) (DDR3U). Le processeur n'est pas compatible avec la mémoire DDR3U et si vous branchez de la mémoire DDR3U sur la carte mère, cela peut endommager physiquement le module DIMM ou provoquer un dysfonctionnement du système. Pour que le système fonctionne correctement, les modules mémoire DDR3-SDRAM DIMM doivent être : ● standard à 240 broches ● sans tampon, non-ECC PC3-12800 DDR3-1600 MHz ● 1,5 volt DDR3-SDRAM DIMM Les modules mémoire DDR3-SDRAM DIMM doivent également : ● prendre en charge une latence CAS 11 DDR3 1600 MHz (synchronisation 11-11-11) ● contenir les informations JEDEC SPD obligatoires En outre, l'ordinateur prend en charge : ● les technologies de mémoire non-ECC à 512 Mbits, 1 Gbit et 2 Gbits ● les modules DIMM monoface/double face. ● Modules DIMM conçus à partir de dispositifs DDR x8 et x16 ; Les modules DIMM conçus à partir de SDRAM x4 ne sont pas pris en charge REMARQUE : Le système ne fonctionnera pas correctement si vous installez des modules DIMM non pris en charge. 102 Chapitre 4 Mise à niveau du matériel de l'ordinateur compact (SFF) Remplissage des supports DIMM La carte mère est équipée de quatre supports DIMM, deux par canal. Ceux-ci sont identifiés DIMM1, DIMM2, DIMM3 et DIMM4. Les sockets DIMM1 et DIMM2 fonctionnent sur le canal mémoire B. Les sockets DIMM3 et DIMM4 fonctionnent sur le canal mémoire A. Le système fonctionnera automatiquement en mode canal unique, en mode double canal ou en mode flexible. Cela dépendra de l’installation des modules DIMM. ● Le système fonctionne en mode canal unique si les supports DIMM sont remplis dans un seul canal. ● Le système fonctionne en mode performant entrelacé à deux canaux si la capacité totale des modules DIMM du canal A est égale à celle des modules du canal B. Cependant, la technologie et la capacité des modules peuvent être différentes entre les deux canaux. Par exemple, si le canal A comporte deux modules DIMM de 1 Go et le canal B un module de 2 Go, le système fonctionnera en mode double canal. ● Le système fonctionnera en mode flexible si la capacité mémoire totale des modules DIMM du canal A n'est pas égale à la capacité mémoire totale des modules DIMM du canal B. En mode flexible, le canal occupé par le moins de mémoire représente la mémoire totale attribuée au double canal et la mémoire restante est attribuée au canal unique. Pour obtenir une vitesse optimale, les canaux doivent être équilibrés afin que la quantité la plus élevée de mémoire soit répartie entre les deux canaux. Si un canal dispose de plus de mémoire que l'autre, la plus grande capacité doit être attribuée au canal A. Par exemple, si vous occupez les sockets avec un module DIMM 2 Go et avec trois modules DIMM 1 Go, le canal A devra être occupé par le module DIMM 2 Go et par un module DIMM 1 Go. Le canal B devra être occupé par les deux autres modules DIMM 1 Go. Dans cette configuration, 4 Go sont exécutés en tant que double canal et 1 Go en tant que canal unique. ● Quel que soit le mode, la vitesse de fonctionnement maximale est déterminée par le module DIMM le plus lent du système. Installation des modules DIMM ATTENTION : Avant d'ajouter ou de retirer des modules mémoire, vous devez déconnecter le cordon d'alimentation et attendre environ 30 secondes pour éliminer toute énergie résiduelle. Quel que soit l'état de mise sous tension, une tension est toujours fournie aux modules mémoire tant que l'ordinateur est branché sur une prise secteur active. L'ajout ou le retrait de modules mémoire alors qu'une tension est toujours présente peut endommager de manière irrémédiable les modules mémoire ou la carte mère. Les supports de modules mémoire ont des contacts en métal doré. Lorsque vous mettez à niveau la mémoire, il est important d'utiliser des modules mémoire avec des contacts en métal doré pour éviter la corrosion et/ou l'oxydation due à l'incompatibilité des métaux en contact les uns avec les autres. L'électricité statique peut endommager les composants électroniques de l'ordinateur ou des cartes en option. Il est conseillé de toucher un objet métallique relié à la terre avant de commencer l'installation. Pour plus d'informations, reportez-vous à Décharges électrostatiques à la page 173. Lorsque vous manipulez un module de mémoire, ne touchez aucun contact, vous risqueriez d'endommager le module. 1. Retirez/dégagez tout périphérique de sécurité qui gêne l'ouverture de l'ordinateur. 2. Retirez tout support amovible de l'ordinateur, par exemple des CD ou des lecteurs flash USB. 3.
