冲突证据的融合方法研究*

证据理论是处理不确定问题的重要方法，但在现实中不同来源的证据往往存在相互冲突，采用合适的方法对其进行融合是解决这一问题的有效手段。讨论了D-S证据合成规则存在的问题和相对于其他合成方法的优势，提出了评价合成规则融合效果的指标，重点对几种证据合成方法进行分析和比较，指出其特点与不足，提出进一步研究的方向。

Research on fusion of conflict evidence

The theory of evidence is important for solving uncertain problem, but in reality the evidence from different sources often exists in conflict with each other, so finding a good fusion method is an effective tool to deal with conflict evidence.This paper discussed the problem in combination rules of D-S evidence and the advantages to the other combination methods,proposed some standards for evaluating the fusion result.analyzed and compared typical methods for combination of evidence,pointed out several problems for further research.
