摘　　要：采用数学变换的手段将基于模糊集合的模糊可靠度计算方法进行了修正,解决模糊强度隶属函数为连续型函数的模糊可靠度计算问题,简化计算过程。文中分析了修正后的方法与基于模糊安全事件概率表示的模糊可靠度计算方法的联系。By using mathematical transformation, the calculation method of fuzzy reliability based on fuzzy set is modified. It helps to solve the calculation problem of fuzzy reliability in which fuzzy strength membership function is continuous function, and to simplify the calculation. This paper analyzes the relationship between the modified method and the calculating method for fuzzy reliability based on the probabilistic presentation of fuzzy safety event
