复杂设备的模糊综合诊断理论及算法

在模糊综合评判理论基础上，首先建立起复杂设备系统在相同和不同诊断评价集下模糊综合诊断的一般模型，给出了多种诊断原则下模糊运算法则，建立了故障诊断中特征知识分类、模糊特征隶属度和权系数的生成方法；在综合诊断模型的基础上，讨论了不同层次和侧面诊断的综合问题，提出在３种不同群专家诊断原则下基于知识的模糊综合诊断算法，依据提出的３种算法可以灵活地实现不同诊断专家对多人、多层次、多目标综合诊断问题的合作求解

The Theory and Algorithm of Fuzzy Comprehensive Diagnosis for Complex Equipment System

Based on fuzzy comprehensive evaluation theory, a general model of fuzzy comprehensive diagnosis (CDM) is developed under the same or different diagnosis evaluation set for complex equipment system.Fuzzy operation model under multiple diagnosis rule (DR) is summarized and the distinguishing of diagnosis feature knowledge and the assigning methods of subordination and weights of fuzzy feature are proposed. Then taking the CDM as basic models,the authors discusse synthesizing among diagnosis unit of different layers, propose knowledge-based fuzzy comprehensive diagnosis algorithms under three kinds of group experts diagnosis rules. Finallya real case is introduced. According to the three kinds of algorithms proposed in this paper, the cooperation solving of different diagnosis experts for multi-person,multi-layer,multi-objective comprehensive diagnosis problems (M3CDP) is available.
