| Abstract: | A new approach to fault diagnosis on D-S theory of evidence and AHP was discussed. The method of constructing the functional form of basic probability assignment on AHP was proposed. Finally, the process of its application was expatiated in a case of fault diagnosis. When combining these pieces of evidence supported by different sensors, the reliability of the diagnostic result improved evidently and its uncertainty was reduced obviously. Therefore, this approach to fault diagnosis is reasonable and effective. |
