【摘要】 智能多代理者系统(MAS)为电子设备的故障定位和诊断提供了一种新的分析和求解思路。本文展示了应用MAS体系结构设计和实现的智能故障诊断系统——MDIDS。文章首先介绍MDIDS系统的数据结构——分为三个层次的代理者群体,给出了系统中代理者的知识表示。然后说明MDIDS使用的诊断推理算法,并提出了一种新的基于估价函数的故障状态空间搜索算法。该算法能够实现对复杂电路的快速故障定位。文章最后总结了MDIDS系统的特点和将来的工作。更多还原

【Abstract】 Intelligent multi - agent system (MAS) provides a brand - new method for fault location and diagnosis in electronic devices. This paper introduces MDIDS- an intelligent fault diagnosis system that is designed and implemented with the concept of MAS architecturc.Firstly.it presents the data structure of MDIDS,a three- layer a-gent community and gives the knowledge presentation of the agent in this system. Secondly, the fauit reasoning algorithms used in MDIDS is illustrated in details. It demonstrates a new fault searching method - cost function based status space search algorithm. It performs a fast fault - locating for complex circuit. Finally, the characteristics of MDIDS system and future plans are summarized in this paper.更多还原
