摘　　要：Dempster证据组合规则无法有效处理高冲突证据组合问题,往往引发反直观结果.针对这一问题,提出一种新的证据推理方法.该方法通过建立一个目标规划模型来获得各信源最优的属性权重向量,进而基于投影法对各个目标方案在区间型理想点上的投影进行排序.实验结果表明,所提出的方法能够有效应对高冲突证据组合问题.The Dempster’s rule of combination cannot efficiently handle highly conflicting evidence combination, because it can arouse counter-intuitive behaviors. Therefore, a novel evidence combination approach is proposed. Firstly, an objective programming model for determining the ideal attribute weights is proposed by considering in local. Then, the alternative is ranked by utilizing the projection on the interval ideal point. Finally, illustrative examples show that the proposed method can effectively handle conflicting evidence combination.
