故障诊断群体决策理论的研究

Research on Group Decision Theory in Fault Diagnosis

文章把群体决策理论作为一种诊断决策方法引入到设备故障诊断领域,解决了在多专家会诊中对专家意见进行一致性分析和故障决策的问题。提出了一种“树型语言模糊量化方法”,并在此基础上构造了一套符合故障诊断特点的数据分析方法。最后举例说明了群体决策理论在故障诊断工作中的实施步骤,表明了该分析方法的可行性和有效性。

By introducing group decision theory into the field of facility fault diagnosis as a kind of diagnosis decision method in this paper, we solve the problem of consistency analysis and fault decision of experts＇ opinion in multi-expert consultation. Propose “Fuzzy Quantization Method based on Tree-shape Language （FQMTL）”. On the basis of FQMTL, we construct a set of data-analyzing method fitted for fault diagnosis. At last the example illustrates steps of group decision theory in the field of fault diagnosis and demonstrates its feasibility and effectiveness.
