Major researches in the domain of complex systems are interdisciplinary, collaborative and geographically distributed. The purpose of our work is to explore a new methodology that facilitates scientist's interactions during the simulation process. Through the analysis of the collaboration and multi-disciplinarity in a simulation project, we have identified the needs of a generic specification (meta-model) of simulator that will be integrated in a collaborative platform. This meta-model is a combination of three basic definitions: simulator, role and user. Accordingly, our meta-model has been developed to help identifying collaboration in simulation. In this paper, we will present our meta-model and an application of it in a simulation project.
