Combination rules which fusing multi evidence with various credibility were given. The traditional Dempster Shafer rules often result in wrong conclusion due to the difference of credibility from multi evidence. A new belief function was derived with λ joining in. λ is a parameter of expected credibility change in evidence authority. Evidences are first transferred according to their λ and then are combined. The method was applied to the power network expert. Compared with the traditional D S theory this method improves the decision making accuracy.
