摘　　要：针对空战目标威胁评估问题,综合考虑了主观和客观因素,将运用区间层次分析法(In-terval-based AHP,IAHP)求解出的威胁评估指标主观权重与运用离差最大化法求解出的威胁评估指标客观权重相融合得到组合权重。建立了改进的TOPSIS法评估空战目标威胁的数学模型,首先构造加权规范化决策矩阵,其次确定区间型正理想解和负理想解,然后计算每个目标分别到正理想解和负理想解的距离,最后计算每个目标对理想解的贴近度。给出评估实例,在3种不同权重影响因子组合的情况下,最终求解得到相同的目标威胁评估排序,评估结果表明:该方法合理有效,并针对原方法有了较大改进。With regard to the problem of target threat assessment for air combat.In the improved TOPSIS the subjective and objective factors are synthetically taken into account,so the combination weight is gained by combining the subjective weight of threat assessment index gained by IAHP with the objective weight of threat assessment index gained by the maximal deviation.The mathematical model of evaluating target threat for air combat by improved TOPSIS is established.Firstly,a Canonical decision-making matrix is established;secondly inter-zone positive and negative ideal solutions are fixed;thirdly the distances are calculated between every target and positive（negative） ideal solutions.Finally,the correlation between each target and the ideal solution is calculated.An application example is given and the results show that target threat assessment indexes are the same under three different combinations of weight factors and the method is reasonable and effective.
