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,并给出运算实例
The concept of triangular fuzzy numbers is introduced into the analysis of fault tree, and a fuzzy representation method - 3σ characterization method is given. Applying the algebraic algorithm of trigonometric fuzzy number to find the fuzzy probability of the overhead event and giving the operation example
