摘要
事故树分析要求上、下两层事件之间具有严格的逻辑关系 ,在大多数系统中这一点很难满足。本文提出了模糊逻辑关系及模糊概率的新概念 ,用于解决这个问题。文中给出了模糊与门逻辑关系和模糊或门逻辑关系的模糊概率计算公式 ,并分析了一个应用模糊事故树的实例。
It is difficult to fit the condition in majority sys tems that there is a rigid logic relation between previous event and the next event.The Paper puts forward a new concept of fuzzy logic relation and fuzzy probability to solve this problem,and presents a fuzzy probability formula of fuzzy and-gate logic relation and fuzzy or-gate logic relation,and analyses an example that it is in application of fuzzy fault tree.
