There are the advantage of Rough Sets Theory and evidence theory for processing uncertain information, and one fusion approach of fault diagnosis based on the Rough Sets Theory and Dezert-Smarandache Theory.Firstly the abundant condition attribution was reduced through Rough Sets Theory, then evidence combining results of each reduced result were calculated through the basic probability assignment and normalized attribution significance.The diagnosis results were combined by DSmT combining equation.Finally the above method was applied to some equipment diagnosis to verify its effectiveness.
