作战效能评估需面向不同的评估数据源，例如仿真数据、专家评估数据以及实测数据等,这些数据分别对应不同的评估准则，有时甚至会包含相互矛盾的信息。因此如何有效地融合不同的数据源，建立稳健的效能评估方法成为基于多源信息效能评估的关键问题之一。基于DS推理方法针对效能评估不同的信息源进行决策融合，考虑到不同数据源之间可能存在的矛盾决策问题，分别通过组合规则和证据源两个方面的修正，建立了修正的DS证据推理融合算法。

Nowadays,there exist different data sources in combat effectiveness evaluation,such as simulation data,expert evaluation data,and measured data.The various data may contain different evaluation criteria,and even sometimes contain contradictory information.How to effectively fuse the different data sources to build up a robust effectiveness evaluation method has become one of the key problems in effectiveness evaluation.In this paper,different evaluation methods are used for different information sources and decision fusion is made based on DS reasoning.Considering that contradictory decisions may exist among different data sources,a revised DS evidence theoretical formula is established by revision of both the combination rule and evidence source.Thus a modified DS evidence reasoning is established.
