Advantages of rough sets theory and evidence theory for processing uncertain information are combined to es-tablish one fusion approach of fault diagnosis based on the rough sets theory and dezert-smarandache theory .Firstly the a-bundant condition attribution is reduced through rough sets theory ,then evidence combining results of each reduced result are calculated through the basic probability assignment and normalized attribution significance .The diagnosis results are com-bined by DSmT combining equation .Finally the above method is applied to some equipment diagnosis to verify its effective-ness .
