Book Description
L'OBJECTIF DE NOS TRAVAUX DE RECHERCHE EST DE CONTRIBUER AU DEVELOPPEMENT DU MODELE GRAI ET DES METHODES ASSOCIEES, EN VUE DE CONCEVOIR, DEVELOPPER ET IMPLANTER LES SYSTEMES DE PRODUCTION. NOUS PROPOSONS UNE ADAPTATION DES CONCEPTS AFIN DE PRENDRE EN COMPTE LE NOUVEAU CONTEXTE INDUSTRIEL. LA NECESSITE DE PILOTER DE FACON PRECISE LE SYSTEME DE PRODUCTION NOUS A CONDUIT A COMPLETER LES REGLES RELATIVES A LA COORDINATION DANS LES STRUCTURES DECISIONNELLES, A DEFINIR UN MODELE DE REFERENCE DES SYSTEMES DECISIONNELS DE PRODUCTION, AINSI QU'UNE EXTENSION DU MODELE GRAI A LA GESTION INDUSTRIELLE, PRENANT EN COMPTE LE CYCLE DE VIE DU PRODUIT. CES TRAVAUX DE RECHERCHE ONT ETE MIS EN UVRE A TRAVERS TROIS PROJETS INTERNATIONAUX DANS LE CADRE DES PROGRAMMES ESPRIT ET IMS (INTELLIGENT MANUFACTURING SYSTEMS)

Book Description
In today's changing world, enterprises need to survive in an ever volatile competitive market environment. Their success will depend on the strategies they practice and adopt. Every year, new ideas and concepts are emerging in order for companies to become successful enterprises. Cross Border Enterprises is the new 'hot' topic arising in the business process world at present. Many terms have been coined together and are being driven in the popular business press to describe this new strategy of conducting business, ie. Extended Enterprise (Browne et al. , 1995; O'Neill and Sacket, 1994; Busby and Fan, 1993; Caskey, 1995), Virtual Enterprise (Goldmann and Preiss, 1991; Parunak, 1994; Goranson, 1995; Doumeingts et al. , 1995), Seamless Enterprise (Harrington, 1995), Inter-Enterprise Networking (Browne et al. , 1993), Dynamic Enterprise (Weston, 1996) and so on. Many people have argued that they mean the same thing, just using different words. Others feel they are different. But how different are they? In this paper the authors will present some basic lines required from this new strategy for conducting and coordinating distributed business processes (DBP), as well as trying to clarify the particularities of two of the widest spread terms related to it: Virtual and Extended Enterprise. 2 CLUSTERS OF PRESSURES The business world currently faces an increased trend towards globalisation, environmentally benign production and customisation of products and processes, forcing individual enterprises to work together across the value chain in order to cope with market influences.

Book Description
This volume contains the selected manuscripts of the papers presented at the Second IDMME Conference on "Integrated Design and Manufacturing in Mechanical Engineering", held in Compiegne, France, at the University of Technology of Compiegne, May 27-29, 1998. The purpose of the Conference was to present and discuss topics dealing with the optimization of product design and manufacturing processes with particular attention to (1) the analysis and optimum design of mechanical parts and mechanisms (2) the modeling of forming processes (3) the development of computer aided manufacturing tools (4) the methodological aspects of integrated design and manufacturing in adapted technical and human environments. The initiative of the conference and the organization thereof is mainly due to the efforts of the french PRIMECA group (Pool of Computer ResoUfces for Mechanics). The international Institution for Production Engineering Research (C.I.R.P.) was helpful to attract international participants. The conference brought together three hundred and twenty worldwide participants.

Book Description
This handbook focuses on a series of concepts, models and technologies which can be used to improve current practice in life cycle engineering in manufacturing companies around the world. Experts on the main issues relating to life cycle engineering have produced a superb collection of chapters. All the contributing authors are researchers and engineers in the fields of manufacturing paradigms, enterprise integration, product life cycle and technologies for life cycle engineering. Academics and researchers will find this book to be a valuable reference tool. The book illustrates those key factors that ensure successful enterprise and product life cycle integration. Due to the book being developed as a joint industry and university project, its approach should be helpful to both practising professionals and academics. An overview of life cycle engineering concepts, models, methodologies and practices that have been proved to significantly improve the integration and productivity of manufacturing companies have been clearly explained in this handbook. This book will be essential for engineers, designers, product support personnel dealing with enterprise engineering projects. It will also be of immense use to lecturers and senior lecturers working in the fields of enterprise integration, product development, concurrent engineering and integrated manufacturing systems.

Book Description
Les travaux du GRAI (Groupe de Recherche en Automatique Intégrée) se sont attachés, depuis de nombreuses années, à modéliser la structure décisionnelle des systèmes de production. Le modèle GRAI décompose l'organisation décisionnelle en différents niveaux de conduite allant du long terme au court terme. Le modèle GRAI permet également d'effectuer la modélisation, l'analyse et la conception de systèmes de production. Ceci s'effectue en suivant un cheminement appelé démarche de GIM. Nos travaux s'inscrivent d'une part, comme la modélisation des connaissances nécessaires pour la conception des systèmes de production dans un environnement GRAI. Ces connaissances peuvent être explicites (modèles de référence, règles, ) ou tacites (anciennes études capitalisées). D'autre part, il s'agit de mettre en place pour la phase de conception de la méthodologie GRAI, un processus de conception simple, efficace et une formalisation de la conception de systèmes de production en vue de l'élaboration d'une aide informatique. Cette approche théorique est utilisée pour l'élaboration des spécifications du système hybride (GRAIXpert) d'aide à l'expertise pour le diagnostic et la conception de systèmes de production, représentant un sous-module de e-MAGIM. Nous proposons également une méthode de résolution de problèmes, basée sur plusieurs types de raisonnements (CBR, Décomposition, transformation, ..) pour faciliter le développement de GRAIXpert.

Book Description
An authoritative source about methods, languages, methodologies and supporting tools for constructing information systems that also provides examples for references models. Its strength is the careful selection of each of the above mentioned components, based on technical merit. The second edition completely revises all articles and features new material on the latest developments in XML & UML. The structure follows the definition of the major components of Enterprise Integration as defined by GERAM (Generalised Enterprise Reference Architecture and Methodology). 1st edition sold about 600 copies since January 2003.

Book Description
Cette thèse présente une méthode de conception des systèmes dans le domaine de la productique. Elle s'appuie sur un modèle conceptuel d la production, composé d'un ensemble de concepts permettant une structuration globale et une structuration détaillée. La méthode GRAI est ensuite présentée avec des exemples d'application et son extension à la conception des systèmes flexibles de production.
