We are located in the context of the simulation of complex industrial systems, which are distributed in geographical, decisional and informational terms. This paper is divided into three parts. The objective of the first one is to position us within the studying framework of a modeling and specification methodology proposed by (Galland et al. 1999). We expose, by the way of a short state of the art, the considerated approach. The second part is dealing with a multi- agent model corresponding to the first stage of our methodology development. Finally we conclude by the application of this model to a teaching case.
