Abstract: Multi-agents approach is such as the problem resolution is located beyond the complexity of agents system and resides in the multitude interactions between the system components. These multitude interactions, if they permit the resolution of complex problem, also lead to conflicting situations and situations which are undertaken by agents of the redundant actions. Then, it becomes necessary to coordinate the existing interactions between agents, in order to structure their activities. This problem is tackled through the notion of the organization that is one of fundamental aspect of multi-agents paradigm. In this paper, we propose a model for the description of agents society based on the description and with an explicit manner, of models of agents, of interaction models in view of an adaptive organization.
