模糊可靠性分析中的隶属函数确定

在可靠性分析中使用模糊方法可以处理实际工程中遇到的模糊问题，而使用模糊方法的根本问题就是确定模糊概念的隶属函数。根据实际需求，以待定系数法作为隶属函数确定的基础方法，通过分析具体隶属函数的分布特性与实际工程背景的关系，归纳总结了隶属函数确定的一般性原则，并结合具体可靠性实例进行了验证。

Determination of Membership Function in Fuzzy Reliability Analysis

Fuzzy method can be employed in reliability analysis in order to deal with the fuzzy uncertainty, and the critical problem of its application is the determination of the membership function of the fuzzy concept.In this paper, the genenral principle about determination of membership function was concluded through analyzing the relationship between the distributing characteristic of membership function and engineering background. Finally, an application example was given to validate the principle.
