Dempster-Shafer theory is an effective method for dealing with uncertainty problems.It can combine evidences from different sources and therefore it has been successfully applied in many domains.However,its application is limited by the shortcomings of D-S evidence combination method.The D-S evidence combination method may be useless when the conflict among evidences is rather great or even complete.Yager had presented some modified combination methods,but these methods have some deficiencies.According to the importance of the evidences,the paper is concerned with a new evidence combination method with introducing weight factors and allotting the conflicted probability again.This method improves the rationality and reliability of the evidence combination and better results can be acquired.
