Based On Mas Coordination Mechanism Of The Agricultural Expert System Development Platform

The paper mainly discusses the Cooperation Mechanism in Multi-Agent System basing on the analysis of the present intelligent agent technology and theory. MAS cooperation methods such as Contract Net Mechanism, Functionally Accurate Cooperative, Coalition Formation, Joint Intentions are analyzed. When these methods are adopted, some factors to be considered are also presented.MAS is the muster of many agents which can do network computing. Each agent paddles its own canoe, can act on itself and environment, can reflect the change of environment. The most important thing is agent can communicate, cooperate with other agents to complete the common complicated task. This is the emphase of my paper.The aim is to build cooperation model of MAS to realize the cooperation in .NET environment. To overcome several defects in solving real problem, a concept of relation web is introduced, then an extension of the contract net model is presented, which chooses strategy dynamically during negotiation. The model is applied to the development of expert system platform. The strategy of negotiation based on relation web can reduce cost of communication, and can compute effectively during negotiation. At the same time, the paper discusses the realizing techniques and offers a realization project of Web Services-Based MAS Cooperative Mechanism. This project not only perfects and enriches the theory of MAS cooperative mechanism, but also offers an effective method or realizing technology for the development of a practical MAS.
