This method is still cited DS evidence theory synthesis formula and redistribute the main evidence source. This study has considered importance of fusion system's evidence and use the evidence right to express the conflict distance. It also considered different evidences to the same focal with different support. Evidence consistency and the concept of focal importance to recombine the source information have been used. Finally, through the synthesis formula of the DS evidence theory to fusion the evidences, compared with other scholars algorithm and it has been found that the results of the new algorithm is perfect and could solve the problem of one ticket veto and other DS theorys defects.]]>Cheng, L., L.
