Abstract：An unrealistic fusion result may be produced when fusing high-conflict evidences by using the classical D-S Evidence Theory. For this reason, to describe the conflict and uncertainty of evidence, the certainty indexes of evidence are determined based on information entropy, and the credibility and falsity of evidence are modified by these certainty indexes to construct the objective weight of evidence. Meanwhile, the index corresponding to the maximum of comprehensive weight is used as a benchmark to construct a discount factor to actualize the optimization of evidence source. A case study on a high-filled section of channel in Middle Route of South-to-North Water Diversion Project shows that conflict evidence can be fused well and the paradox of fusion can be avoided effectively by adopting the evidence discount factor method based on information entropy.
