摘　　要：鉴于 2型模糊集对于模糊现象的描述更为深刻的特点 ,将系统的模糊成功和模糊故障用 2型模糊集表示 ,引入模糊随机变量等数学工具对率模系统可靠性进行了分析 ,得到了率模可靠度 ,率模寿命 ,率模故障率等结论 ,推广了文献The type 2 fuzzy sets have the character that can describe the reality much more deeplier, so in this composition, we use type 2 fuzzy sets to describe fuzzy success and fuzzy failure. Then we utilize such mathematical tools as fuzzy random variable to analyze the reliability of profust system and get such results as profust reliability, profust lifetime and profust failure rate which are the generalization of some results in [1].

关 键 词：模糊集合 系统可靠性 寿命期限 故障率
