摘要
复杂系统中广泛存在着模糊问题,故障与征兆之间的关系更具有模糊性。首先简要介绍了模糊评判的基本原理及其数学模型,提出了将模糊综合评判应用于复杂系统故障诊断专家系统的新思路,重点分析了复杂系统知识信息的获取与表示方法,给出了知识库的建立及推理过程。证明了某型导弹测试设备故障诊断专家系统组建方法的可行性。
Complicated systems are usually subjected to fuzzy problems,and the case is quite special in the relations between faults and theirs signs.This paper,first of all,presents a brief introduction to the basic theory and mathematics model of fuzzy judgment,and then applies the use of fuzzy synthesis judgment to fault diagnosis expert system in complex system,together with the analysis of the methods that can acquire the knowledge and the expression methods.Based on this,this paper presents the way to build the knowledge data and the reasoning process.The setup of the expert system in certain missile ATE fault diagnosis proves the realization of this method.
