摘要
将三角模糊数的概念引入事故树分析中，给出一种基本事件发生概率的模糊表征法——３σ表征法。运用三角模糊数的代数运算法则求顶上事件发生的模糊概率。
The concept of triangular fuzzy number is introduced in fauct tree analysis,and a kind of expession method of occurrence probability of basic accidents 3σ expression nethod is given in this paper.We have calculated the fauct tree with the law of trianglar fuzzy number s algebraic operation,thas obtaining the fuzzy probability of top accident,An actual expmple is giver as well.
