摘要
通过分析凝汽器的各种故障类型和征兆,采用基于规则的产生式规则表示法,建立了对分式凝汽器性能诊断专家系统的知识库。由于事实和规则的不确定性,采用隶属度和可信度处理模糊知识,以性能诊断知识库中的一条规则为例,计算了征兆的隶属度和规则的可信度,为知识库的建立提供了理论基础。
Through analysis of faults and failure symptoms of the condenser, a knowledge base of diagnositic expert system for condenser’s performance has been established by using rule representing method based on regular production mode. Because of the uncertainty of facts and rules, the subordinateness and credibility are used to process the fuzzy knowledge. Taking a rule in knowledge base of performance diagnosis as example, the subordinateness of symptom and the credibility of rule have been calculated, and a theoritical basis for establishment of the knowledge base being provided.
