Book excerpt: Le travail presente s'interesse principalement au recouvrement des pannes materielles dans les sfpm. Cette fonction fait partie de la supervision et collabore avec les modules de surveillance, de gestion des modes et de pilotage afin d'elaborer une reaction lorsqu'une panne survient. Son role decisionnel consiste a determiner comment le systeme peut conserver un caractere operationnel malgre la presence d'une panne. Notre contribution est basee sur une demarche en deux temps, s'interessant a la conception puis a l'exploitation. La premiere partie concerne la tolerance aux pannes et vise a concevoir un sfpm dont la disponibilite reste elevee grace a l'analyse de sa flexibilite. L'approche originale se fonde sur la determination des elements critiques du systeme. Elle permet une analyse a priori des architectures de production et un classement par type. L'analyse de la tolerance participe ainsi a l'aide a la conception des architectures materielles. La seconde partie propose une procedure de reconfiguration qui determine, apres l'apparition d'une panne, la nouvelle configuration du sfpm (les ressources a arreter, celles a mettre en marche). La principale caracteristique est une reaction evolutive, fonction de la difficulte de mise en oeuvre et des imperatifs de production. L'approche est fondee sur une analyse de la capacite du systeme a realiser un type de production donne.

Book excerpt: NOUS AVONS MONTRE DANS CE MEMOIRE QU'UNE APPROCHE DES SYSTEMES DE PRODUCTION PAR LES FONCTIONS ET LES OPERATIONS PERMET D'ALLER BEAUCOUP PLUS LOIN DANS LA SPECIFICATION DES CONTRAINTES DE FONCTIONNEMENT ET DE GESTION DES CONFIGURATIONS ET DES MODES DE FONCTIONNEMENT. NOUS AVONS PRESENTE LA PROBLEMATIQUE DE LA SUPERVISION ET DE LA GESTION DES MODES EN ETENDANT LES CONCEPTS DU GEMMA. EN EFFET IL NE S'AGIT PLUS DE GERER LA MARCHE ET L'ARRET D'UN SYSTEME AUTOMATISE DE PRODUCTION UNITAIRE MAIS DE GERER LES CONFIGURATIONS D'UN SYSTEME FLEXIBLE DE PRODUCTION COMPOSE ET COMPLEXE. LA DEMARCHE QUE NOUS PROPOSONS, DANS UN PREMIER TEMPS, PERMET DE CONSTRUIRE UN MODELE DU SYSTEME DE PRODUCTION, PAR UNE ANALYSE ASCENDANTE DES CONTRAINTES ET DES LIENS DE FONCTIONNEMENT ENTRE OPERATIONS. CETTE TECHNIQUE DE MODELISATION ABOUTIT, DE MANIERE SYSTEMATIQUE, A UN MODELE ARBORESCENT FONCTIONNEL DU SYSTEME DE PRODUCTION. CE MODELE MET EN EVIDENCE LES DIFFERENTS NIVEAUX DE COMMANDE DU SYSTEME FLEXIBLE DE PRODUCTION MANUFACTURIERE ET FAIT RESSORTIR LES PRINCIPES D'ORGANISATION ET DE CONDUITE DES INSTALLATIONS EN SPECIFIANT LEURS LIENS AVEC LES FONCTIONS. L'ORIGINALITE DE CETTE DEMARCHE RESIDE DANS LA POSSIBILITE D'INTEGRER TOUS LES COMPOSANTS D'UNE UNITE DE PRODUCTION. ELLE PERMET AUSSI DE TENIR COMPTE D'UNE MANIERE TRES SIMPLE DE L'AJOUT OU DE LA SUPPRESSION D'UN COMPOSANT. DANS UNE SECONDE DEMARCHE, NOUS AVONS MONTRE COMMENT L'EXPLOITATION DE LA MODELISATION PERMET DE GENERER UNE SPECIFICATION DE LA SUPERVISION DU SFPM. CETTE PHASE DE TRADUCTION EST BASEE SUR LA TRANSCRIPTION DIRECTE DES MODELES DU SFPM DANS UN LANGAGE SYNCHRONE GRAPHIQUE: ARGOS. LA TRADUCTION DE CES ARBORESCENCES SOUS FORME DE PROGRAMMES SYNCHRONES PERMET LA MISE A JOUR REACTIVE DE L'ETAT ET DE LA DISPONIBILITE DES COMPOSANTS DU SYSTEME DE PRODUCTION ET LA TRANSMISSION DES ORDRES DE RECONFIGURATION DE FACON ORIGINALE

Available in PDF, EPUB and Kindle. Book excerpt: In the last decade, the production of mechanical components to be assembled in final products produced in high volumes (e.g. cars, mopeds, industrial vehicles, etc.) has undergone deep changes due to the overall modifications in the way companies compete. Companies must consider competitive factors such as short lead times, tight product tolerances, frequent market changes and cost reduction. Anyway, companies often have to define production objectives as trade-offs among these critical factors since it can be difficult to improve all of them. Even if system flexibility is often considered a fundamental requirement for firms, it is not always a desirable characteristic of a system because it requires relevant investment cost which can jeopardize the profitability of the firm. Dedicated systems are not able to adapt to changes of the product characteristics while flexible systems offer more flexibility than what is needed, thus increasing investment and operative costs. Production contexts characterized by mid to high demand volume of well identified families of products in continuous evolution do not require the highest level of flexibility; therefore, manufacturing system flexibility must be rationalized and it is necessary to find out the best trade-off between productivity and flexibility by designing manufacturing systems endowed with the right level of flexibility required by the production problem. This new class of production systems can be named Focused Flexibility Manufacturing Systems-FFMSs. The flexibility degree in FFMSs is related to their ability to cope with volume, mix and technological changes, and it must take into account both present and future changes. The required level of system flexibility impacts on the architecture of the system and the explicit design of flexibility often leads to hybrid systems, i.e. automated integrated systems in which parts can be processed by both general purpose and dedicated machines. This is a key issue of FFMSs and results from the matching of flexibility and productivity that respectively characterize FMSs and Dedicated Manufacturing Systems (DMSs). The market share of the EU in the machine tool sector is 44%; the introduction of focused flexibility would be particularly important for machine tool builders whose competitive advantage is based on the ability of customizing their systems on the basis of needs of their customers. In fact, even if current production contexts frequently present situations which would fit well with the FFMS approach, tradition and know-how of machine tool builders play a crucial role. Firms often agree with the focused flexibility vision, nevertheless they decide not to pay the risk and efforts related to the design of this new system architecture. This is due also to the lack of well-structured design approaches which can help machine tool builders to configure innovative systems. Therefore, the FFMS topic is studied through the book chapters following a shared mission: "To define methodologies and tools to design production systems with a minimum level of flexibility needed to face, during their lifecycle, the product and process evolution both in the technological and demand aspects. The goal is to find out the optimal trade-off between flexibility and productivity". The book framework follows the architecture which has been developed to address the FFMS Design problem. This architecture is both broad and detailed, since it pays attention to all the relevant levels in a firm hierarchy which are involved in the system design. Moreover, the architecture is innovative because it models both the point of view of the machine tool builder and the point of view of the system user. The architecture starts analyzing Manufacturing Strategy issues and generating the possible demand scenario to be faced. Technological aspects play a key role while solving process plan problems for the products in the part family. Strategic and technological data becomes input when a machine tool builder performs system configuration. The resulting system configurations are possible solutions that a system user considers when planning its system capacity. All the steps of the architecture are deeply studied, developing methods and tools to address each subproblem. Particular attention is paid to the methodologies adopted to face the different subproblems: mathematical programming, stochastic programming, simulation techniques and inverse kinematics have been used. The whole architecture provides a general approach to implement the right degree of flexibility and it allows to study how different aspects and decisions taken in a firm impact on each other. The work presented in the book is innovative because it gives links among different research fields, such as Manufacturing Strategy, Process Plan, System Design, Capacity Planning and Performance Evaluation; moreover, it helps to formalize and rationalize a critical area such as manufacturing system flexibility. The addressed problem is relevant at an academic level but, also, at an industrial level. A great deal of industrial sectors need to address the problem of designing systems with the right degree of flexibility; for instance, automotive, white goods, electrical and electronic goods industries, etc. Attention to industrial issues is confirmed by empirical studies and real case analyses which are presented within the book chapters.

Download or read book Arctic Shipping written by Frédéric Lasserre and published by Routledge. This book was released on 2019-09-05 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book considers both the present state of Arctic shipping and possible future trends with reference to the various sectors of maritime transportation: cruise tourism, container traffic and bulk shipping. Ports are analysed as tools that support the strategies of coastal states to foster the development of resource extraction, enhance the attractiveness of Arctic shipping lanes and enable the control of maritime activities through coast guard deployment. The aim of this book is to draw a picture of the trends of Arctic shipping. How is traffic evolving in Canada’s Arctic, or along the Northern Sea Route? Are there significant differences between bulk and container shipping segments when considering the Arctic market? How are the ports and the hinterland developing and what are the strategies behind those? How is the legal framework shaping the evolution of maritime transportation? The contributors to this book consider all of these questions, and more, as they map out the prospects for Arctic shipping and analyse in detail the development of Arctic shipping as a result of multi-variable interactions. This book will be key reading for industry professionals and post-graduate students alike.

Download or read book Strategic Management of Innovation and Design written by Pascal Le Masson and published by Cambridge University Press. This book was released on 2010-09-09 with total page 488 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is now widespread agreement that innovation holds the key to future economic and social prosperity in developed countries. Experts studying contemporary capitalism also agree that the battle against unemployment and relocations can only be won through innovation. But what kind of innovation is required and what is the best way to manage, steer and organize it? Grounded on experiences of innovative firms and based on recent design theories, this book argues that instead of relying on traditional R&D and project management techniques, the strategic management of innovation must be based on innovative design activities. It analyses and explains new management principles and techniques that deal with these activities, including innovation fields, lineages, C-K (Concept-Knowledge) diagrams and design spaces. The book is ideal for advanced courses in innovation management in industrial design schools, business schools, engineering schools, as well as managers looking to improve their practice.

Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and dis· seminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) *at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the ac· tivity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volume were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 20 (thesis year 1975) a total of 10,374 theses titles from 28 Canadian and 239 United States universities. We are sure that this broader base for theses titles reported will greatly enhance the value of this important annual reference work. The organization of Volume 20 is identical to that of past years. It consists of theses titles arranged by discipline and by university within each discipline.

Download or read book Multi party Elections in Africa written by Michael Cowen and published by . This book was released on 2002 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains electoral studies of multiparty politics in 14 African countries during the 1990s. Most are about national elections in Anglophone Africa. There are also less well-known examples from Sudan, Ethiopia and Guinea Bissau. The collection also features studies of the local elections in Namibia and of a significant by-election in Malawi. The multiparty period had been put, wherever possible, within the historical context of earlier elections in Africa. Questions addressed include: how did incumbent governing regimes learn to live with multiparty politics? Why have some elections been so closely fought and others have suffered from apathy? Why has there been relatively open political expression and activity when the elections have increased the political and economic manipulation by incumbent governments? Why have the elections of the 1990s been so marked by local and ethnic variations? To what extent did this wave of democracy result from pressure from donor countries?
