摘要
为了对不确定的故障关系进行描述和分析 ,提出了模糊故障图。定义并分析了它的代数基础—模糊间集、间集的链关系及一些相关概念 ,提出了基于模糊故障图进行故障诊断的方法 ,并应用于实际系统 ,较好地实现了模糊故障诊断。模糊故障图可以有效地描述复杂系统的故障关系 ,实现模糊的系统故障分析。
To describe and analyze the uncertain fault relation,fuzzy fault graph was presented.Its mathematics foundation,named fuzzy Mid Set and some other relevant conceptions,were defined and analyzed.So the structure and property of fuzzy fault graph became definite.Then the method of fault diagnosis based on fuzzy fault graph was also put forward.When the method was used in a factual system analysis,the fuzzy fault diagnosis was realized preferably.The fuzzy fault graph can be used in describing the fault relationship of complicated system effectively and realizing the fuzzy fault analysis preferably.
