故障诊断专家系统中知识一致性检查算法的研究

知识库是故障诊断专家系统的推理依据,新规则的添加改善了系统的故障诊断能力,同时可能会导致新规则和原知识库中的规则冗余、闭路循环、矛盾等一致性问题,造成系统不稳定,甚至推理错误。本文从知识一致性入手,提出解决新加规则和原有规则的冗余、闭路循环、矛盾的判断算法,并用C 较好的解决了知识一致性检查算法问题。

Research of algorithm for consisitency checking on expert system of fault diagnosis

The reasoning of fault diagnosis expert system is based on Knowledge Base,the addition of new rules could improves the ability of fault diagnosis,but also may bring some problems such as rule redundancy,closed cycle or contradiction between new rules and original Knowledge Base,these problems could cause the system's instability even fault conclusion.This paper bring a new estimation algorithm to solve the problems of Knowledge Base consistency and tested in computer with C program.
