摘　　要：将模糊集合论应用于可靠性设计，建立了戒上型、戒下型及对称型隶属函数与不同概率密度函数相遇时的模糊可靠度计算模型，为模糊可靠性的设计计算提供了理论依据和便利。最后，对公式作了简要的说明，并给出了使用示例。Upper Limit, lower limit and symmetry membership functions are reformed and the suitable ranges of them are explained. The basic concept and method of fuzzy mathematics are used in this paper. Based on the combination integration between membership functions and different probability density functions, Fuzzy reliability calculation models are set up. Detailed explanations on the models are given and some applied examples show the correctness and generality of the models.
