Production dynamic scheduling method based on improved contract net of multi-agent

Abstract

To solve the dynamic and complex problem of production scheduling, this paper proposed a new production dynamic scheduling method based on improved contract net of multi-agent. In this method, a production dynamic scheduling framework model based on multi-agent was built, and each agent function was analyzed in detail. An improved contract net was investigated by means of spirit parameters. By means of improved contract net, the negotiation procedure between scheduling negotiation agent and resource agent was constructed by improved contract net multi-agent. Finally, the simulation system of production dynamic scheduling based on improved contract net of multi-agent was demonstrated and validated by QUEST software. It has shown the proposed method can improve the benefit of production scheduling, and provide a support for adapting to complex and dynamic production scheduling. © 2013 Springer-Verlag.
