基于多源信息和改进证据理论的空战攻击决策

Attacking Decision-Making of Air Combat Based on Multi-Source Information and Improved Evidence Theory

针对证据理论不能有效地处理带冲突证据信息的缺点,结合已有的证据理论改进算法研究了一种新的多源信息融合策略并应用于多机协同空战决策。根据不同的前提条件采用不同的融合规则,并在融合过程中引入可靠性度量,以反映具体证据的信任度。同时采用闭世界和开世界的观点,区别两种不同部分冲突信息的分配并考虑融合的顺序,提高冲突证据的融合效率。仿真结果表明所研究的融合策略能够得到较好的空战攻击决策结果。

In order to overcome the shortcoming of evidence theory of being unable to deal with evidence with high conflict effectively, a new multi-source information fusion strategy is given based on the existing improved evidence theory algorithm. The proposed fusion strategy is used for multi-aircraft cooperative decision-making in air combat. In this strategy, different combination rules are taken for different preconditions, and reliability measurement is introduced to reflect the credit of specifically evidences. The concepts of open world and closed world are used, the assignment of different parts of the conflict information is distinguished, and the order of fusion is taken into account either. The new strategy can improve the fusion efficiency of conflict evidences and a better decision of attacking strategy is indicated through the experiment results of the given example.
