| Abstract: | A new approach to fault diagnosis on D-S theory of evidenceand AHP was discussed.The method of constructingthe functional form of basic probabilityassignment on AHP was proposed.Finally,the process of its application was expatiatedin 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. |
