摘要
对具有模糊性的各种系统和问题,用常规可靠性理论和方法对其进行描述非常困难,甚至是不可能的。为解决这个问题,提出了一种模糊可靠性的计算方法,它重点解决工程实际中的随机应力———模糊强度模型。该计算模型的数学基础是,模糊可靠性可以用常规概率通过数学转换来计算。基于这种计算模型,提出一种计算鱼雷圆柱形壳体模糊可靠性的方法,它为可靠性分析建立了一种系统组成单元模糊可靠性的基础。实例计算结果证明,该方法与工程实际一致。
A computational model of fuzzy reliability aimed at the solution of engineering problems with random stress-fuzzy strength was presented. Its mathematical basis is that fuzzy probability can be computed with the method of conventional probability by use of a mathematical transition, Based on this, a numerical algorithm was given which can be applied to compute the fuzzy reliability of cylindrical shell. This lays a foundation for the reliability analysis of systems consisting of the components with fuzzy reliability, Computational result fits well with engineering experience.
