Research on Diagnosis Model Distributed Intelligence and Key Technique Based On MAS

摘要

Modern malfunction diagnosis is a dynamic, distributed, flexible, real-time and uncertain complicated system. The paper tried to introduce multi-Agent technology to the complicated malfunction diagnosis. Based on distributed artificial intelligence. The paper analyzed MAS based on distributed intelligent malfunction diagnosis method and process, and discussed pattern-clustering based malfunction solution-finding mechanism and the identification and decomposing of a diagnosis task. It also studied the restriction and relationship of multi-agent in the sense of macroscopic, and designed the expression mechanism for applied agent's work status. Else it ascertained the influence and the communication and the interaction among applied agents, and constructed a multi-agent fuzzy related model. The last aspect is that the paper presented an integrated descriptive structure of local diagnosis decision and global diagnosis decision, and established a distributed agent diagnosis system structure and its prototype model system too. Diagnosis system can be divided into applied agent and service agent, they using distribute communication mechanism to realize intercommunication of information, realize distribute system's information exchange and diagnosis, enhance system's efficiency, security and error-standing for problem-dealing. When the model were applied in the power enterprise's security monitor system the result were similar to expert system, the model overcame many deficiencies of precious monitor diagnosis system, enhanced the efficiency of the enterprise security running. Compared with traditional diagnosis method, the result shows the special advantage in the distributed domain.
