Contribution à la gestion et à la conduite des systèmes manufacturiers par les objets nomades de production

Abstract : The work presented is a contribution towards defining and managing manufacturing systems. The proposed approach is based around the product, taken as an information vector. Each product behaves like an agent which manages and offers necessary information to given machines. The product, an actor in its development process, is characterized by its knowledge and its capacity to co-operate with the manufacturing processes which change its state. Our research work, by taking advantages of automatic identification technologies, proposes the nomadic object concept in production. After a state of the art in the corresponding fields, and a problem analysis concerning the definition and the data management of a product through its life cycle (in particular through the STEP methodology), we detail the nomadic object concept. A framework architecture and a realization methodology are specified which match the concept on mobile data carriers. Specifications of a layered data access interface model are discussed and analyzed. A method on how to generate this interface is also given. Il is based on a logical data model using the EXPRESS modeling language. Finally, we present and discuss a conception method for production systems taken into account the nomadic object concept. These propositions are supported by a tool detailed in this thesis, namely Tag-STEP. Tag-STEP allows us to generate diverse data supports by translating EXPRESS models; distribute information; and automatically configurate the data access interface embedded on the product. A demonstrator has been built to validate the proposed methodology and is based upon a simulation of the flexible assembly cell of the AIP Lorrain.
