基于AHP-Fuzzy和灰关联分析的决策级融合故障诊断

hrough analyzing the currently domestic and foreign research, fusion diagnostic methods based on Analytic Hierarchy Process-Fuzzy (AHP-Fuzzy) with gray correlation analysis are presented. The software simulations of algorithms are made with fault multi-sensor information. The application of the AHP-Fuzzy in information fusion is analyzed in the paper, and used it in the fault diagnosis. It is the key point to obtain the fuzzy relationship between fault symptom and fault type in the application of the AHP-Fuzzy in fault diagnosis. .To the difficulty of obtaining, the fuzzy relation matrix by the output of the gray correlation is presented, establish the partial fusion diagnosis based on AHP-Fuzzy and gray correlation analysis, and execute the whole fusion diagnosis in the basis of the diagnosis results. The diagnosis results indicate that the method can reduce the uncertainty of the decision and greatly enhances the precision of the diagnosis.
