摘要
从模糊可靠性和模糊可靠度的基本定义出发,通过各种模糊逻辑模型的可靠度计算公式,结合专家主观判断法,利用最小割集的概念及其逻辑关系,建立了长输管道模糊故障树并计算出了它的模糊可靠度。
The fuzzy reliability relating to some fuzzy functional set was inquired. The formula of each kind of fuzzy logic model and the expert judgment were passed. With the basic principle of the min set and their logic relationship,the system of oil and gas pipelines was analyzed. Finally, the fuzzyreliability of it was achieved.
