The object-oriented approach allows the development of complex and reliable applications with less effort than with classical approaches. The objectives of this research are, on the one hand, to propose a complete conceptualization of object-oriented simulation models and, on the other hand, to implement them by using concurrent programming techniques. After the presentation of the manufacturing systems and their management in chapter I, we classify the different structure and simulation models for production systems in chapter n. In chapter rn, we propose an analysis method to identify object classes by five domain types: physical, role, incident, interaction and specification. Bach of these classes is specified by four models: communication, information, state transition and process. A general architecture of active objects and of simulation platform and the principal semantic object classes (like transactions, production facilities and decision objects) to establish production simulation models are presented in chapter N. In chapter V we illustrate the implementation of spatial and timing coordination between concurrent objects in the simulation by using the concept of light-weight processes based on the Meijin++ tool.
