A PROPOSAL FOR AN INTEGRATED MODEL OF A MANUFACTURING SYSTEM - APPLICATION TO THE REENGINEERING OF AN ASSEMBLY SHOP

Designing a manufacturing system or, more generally, modelling an exis ting system in order to make it evolve to provide better performance l eads to the use of an integrated methodology. This methodology enables one to understand the system studied for several points of view in a consistent way. This paper presents GIM (GRAI Integrated Methodology) which has been developed within the framework of several ESPRIT projec ts based on the research work developed by the GRAI research group. Th is integrated methodology proposes a conceptual model, several modelli ng formalisms and a structured approach supporting the project. The ma in part of this paper aims at showing a real application of GIM, the p urpose of which was to reengineer an assembly shop.
