In this paper, we propose a technique for the negotiation between agents in the dynamic generation of a production plan in an autonomous production system using product parts agent and assembly machine agents. A part agent leads the promotion of processes in this type of assembly system. This agent generates the process plan that contains the assembly sequence to complete the product. The proposed system is defined as an event driven architecture. The increase in the costs of communication between agents is polynomial in the size of the agents. Moreover, this system adjusts the production schedule dynamically using only local negotiation when conditions will be changed. Finally, we show experimental results with simply examples. r.
