The evidence combination method is the key part of the evidence theory.It can combine the independent evidences from different information sources to acquire more reliable information.However,its application is limited by the shortcomings of Dempster-Shafer evidence combination method.This method may be useless when the conflict among evidences is rather great or even complete.A new evidence combination method is presented.In this improved method,the importance of the evidences is calculated.It enhances the rationality and reliability of the evidence combination through introducing weight coefficients and allotting the conflicted probability again and better results can be acquired.
