摘　　要：战斗机空战效能评估在武器装备研制采购、对比敌我双方作战实力等方面发挥着重要作用,传统评估模型只能在宏观上对空战效能进行评估,无法通过对比不同战机的优劣指标来进行微观评估。借鉴双基点法改进多指标评估模型,构建空战效能评估模型;针对超视距空战和视距内空战,分别建立不同的指标体系;根据评估指标赋权时主观法与客观法存在的缺陷,利用最小信息熵原理综合结构熵和信息熵两种不同类型的赋权技术,构造组合赋权法。算法验证表明:组合赋权法不仅可以反映两种视距条件下指标重要程度的不同特点,而且改进模型能纠正传统模型的评估错误,可以对空战效能进行有效评估。Combat effectiveness evaluation of fighter plays an important role in the development and purchase of weapons and equipment,and in the comparison of the combat strength of both sides.An improved multi-index evaluation model based on technique for order preference by similarity to ideal solution(TOPSIS)is proposed in this article to build an air combat effectiveness evaluation model.This New model improves the shortcoming that the traditional evaluation method can only make a comprehensive evaluation of air combat effectiveness on a macro level,but cannot make a micro evaluation by comparing different aircraft strengths and weaknesses.Different index systems have been established for the over-the-horizon and dogfight air warfare tasks,and according to the defects of subjective method and objective method when evaluating the weights of indicators,the combined weighting method is constructed by using the minimum entropy principle to synthesize the two different types of weighting technologies:structural entropy weight and entropy weight.The algorithm verification shows that not only can the combined weighting method reflect the different characteristics of the index importance degree under the two line-of-sight conditions,but also the improved model can correct the evaluation errors of the original model,indicating that the method proposed in this paper is feasible and effective.
