摘要
传统结构重要度分析方法是基于数值模式（０，１）的方法，是确定的二值问题。本文将模糊熵的概念引入故障树结构重要度分析当中，提出一种重要度分析的模糊法，它是基于非数特征值的模式分类方法，其基本事件可以是多表达式，特别适用于大模式整体结构，同时对二值问题也同样适用。
The traditional analysis method of structure importance is a determined logical problem which is based on numerical mode (0,1). A fuzzy method in the analysis of structure importance for fault tree was put forward in this paper by introducting the concept of fuzzy entropy. It is a pattern recognition method based on non numerical characteristic mode, and its basic events can be multiple expressions. It is especially fit for large mode structure, and the logical problem too.
