可变结构冗余模型的模糊可靠性分析

The Fuzzy Reliability Analysis of Structure Modifiable Redundant System

修正了可变结构冗余模型的定义。应用模糊数学的原理和方法 ,将可变结构冗余模型的经典可靠性拓展为模糊可靠性。定义了模糊正常和模糊故障 ,通过将可靠度和平均寿命时间的模糊化 ,把模糊正常的概念和隶属函数引入模糊可靠度。在模糊可靠性理论的基础上建立了数学模型 ,对可变结构冗余模型进行了模糊可靠性分析 ,并给出实例说明其计算方法。

The definition of structure modifiable redundant model is modified in this paper. The basic theory and method of fuzzy mathematics are applied to expand the classical reliability of the model to fuzzy reliability. It defines fuzzy normal and fuzzy failure. It inducsts concept of fuzzy normal and membership function with fuzzing reliability and average life span. Based on fuzzy reliability theory, the fuzzy reliability model of structure modifiable redundant model is established. An example is given to express the calculating method.\;
