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。
Based on the theory of fuzzy comprehensive judgment, a general model of fuzzy comprehensive diagnosis for complex equipment systems under the same and different diagnostic evaluation sets is established firstly. The fuzzy algorithms are given under different diagnosis principles, and the classification of the characteristic knowledge in fault diagnosis is established. Based on the comprehensive diagnosis model, the comprehensive problems of different levels and side diagnoses are discussed, and the knowledge-based fuzzy comprehensive diagnosis algorithm based on the knowledge of three different groups of experts is proposed. According to the three proposed algorithms, the cooperation of different diagnostic experts can be flexibly solved for multi-person, multi-level and multi-objective comprehensive diagnosis problems.
