Reusable models integration in a DEVS-based modelling and simulation environment

A model can be defined as an abstract description of a system or of a process, a simplified representation which allows the modeller to understand and simulate. Most domains of the Scientific Research use models and involve some software tools, generally designed by a research team. These tools lends themselves quite naturally to the aggregation of libraries of reusable components that will facilitate the description of the models and also their validation. We propose in this article an Object-Oriented architecture for the creation and the management of such Model Libraries. The originality of our approach lies in the facts that it is based on notions like the inheritance and abstraction links between the stored models. These two concepts are very useful for the Final User, since they help him to quickly design complex models.
