This paper presents the application of the multiagent system for modelling supply chains involving Small and Medium Enterprises (SMEs) in the mechatronic industry. This work is a combination of two research scopes. The first one deals with the identification of the different concepts able to model the particular manufacturing systems and production context in Savoie - France. The second one outlines the development process based on an agent modelling approach, which offers an easy and reusable modelling of supply chain concepts.
