Maintaining the interoperability in a dynamic competitive manufacturing environment in which different business enterprises collaborate is difficult to achieve. Our approach highlights negotiation as the best solution to solve interoperability problems by reaching the common decision suitable for all managers of various enterprises in the most optimized amount of time. In this context, this paper proposes a multi-agent negotiation model, able to coordinate several negotiations taking place in parallel among multiple participants. It is described the negotiation strategy for evaluating and generating offers and the protocol for sending the offers to the other agents. This model is being implemented in the H2020 C2NET project for supporting manufacturing.
