Nowadays, in order to meet the demands of the global dynamic market and eliminate its disturbances, the supply chain and its integration across different organizations has become a competitive business advantage along the production processes. In particular, the mechatronic industry is very sensitive to these requirements. Our research deals with modelling the supply chain in order to manage and implement a simulation platform. Basically, we develop a modelling solution for an industrial environment composed of mechatronic Small and Medium Enterprises located in Savoie (France). The study is based on elements from real applications and the SMEs network organization. An analysis of the domain helped us to develop concepts and a modelling approach adapted to these companies. In this work, we present the area studied, the methodology used to construct the conceptual model of the supply chain, its structure and management rules. Then, we present the model obtained. Finally, we apply this conceptual model to a case study.
