LC universal model for the enterprise information system structure

The analysis of the product lifecycle processes is one of the crucial industrial concerns. It highlights the role of knowledge capitalization and valorization. In this work, a generic model is proposed: the FBS-PPRE model (Function, Behav- ior, Structure - Process, Product, Resource, external Effect). The main scientific contribution consists in a conceptual unification making it possible to increase the homogeneity of the represented objects as well as the completeness of the modeling, when addressing all the life-cycle situations of the product, the tech- nologies and the enterprise. In order to allow a description of the various objects handled by the company according to the same formalism, the approach high- lights the distinction between the concepts of nature (material, temporal, soft- ware, organizational or energy) and of role. Four different roles are distin- guished: the role of product (object resulting from the process), of resource (means used in a process), of process (temporal, spatial and hierarchical organi- zation of activities) and of external effect (constraints influencing the course of a process). The same object can play successively various roles during its lifecy- cle. In addition, an effective management of behaviors is proposed: a behavior of an object is always combined with a process element, which makes it possible to define the context. It then becomes easier to manage the evolution of the object and of its representations, namely their transformational dynamic. This approach was implemented within the framework of a demonstrator of information system of a company designing and producing vehicles.
