摘要
基于模糊理论 ,建立了压力管道安全状况等级评判的模糊评判模型 ,提出了压力管道安全状况等级的综合评判方法。模型 1综合评判中引入了水平截集 ,模型 2′通过引入相关系数因子矩阵 ,综合考虑了因素间的相互作用对压力管道安全状况等级的影响。最后 ,给出一算例 。
based on the Fuzzy theory, the Fuzzy model of the comprehensive assessment of the class of safety condition for pressure piping is established, and the comprehensive evaluation methods of the class of safety condition are described. In the model1, the level truncation setting function is presented during the course of comprehensive evaluation. In the model2, the reciprocity of the factors is comprehensively considered to redeem their influence on reliability index by introducing the correlative coefficient matrix. At the end, it is to demonstrate that the models are right by an given example.
