模糊数在系统模糊可靠性分析中的应用

Fuzzy Reliability Analysis of a System by Fuzzy Number

在本文中，我们定义了模糊可靠度为一个模糊数，并用模糊数而不是一个概率值来估计系统的模糊可靠度，同时还在不同的置信水平λ上，用置信区间来确定系统的普通可靠度。

In this paper,the fuzzy reliability is defined as a fuzzy number.A fuzzy number in-stead of a certain probability is used for evaluating fuzzy reliability of a system. And usual reliability of the system with confidence interval at any confidence levelλis obtained.
