基于组合赋权TOPSIS法的空战多目标威胁评估

Multi-target Threat Assessment in Air Combat Based on Combination Determining Weights TOPSIS

针对多目标攻击的空战态势和武器装备的特点,首先提出改进的空战多目标威胁评估量化指标。对组合赋权方法进行研究,提出最小加权隶属度偏差方法作为客观赋权方法,采用线性加权方法作为主客观权重组合赋权方法,并从理论上证明该方法的合理性。将得到的组合权重应用于TOPSIS法作为目标威胁评估解算方法,并进行仿真研究验证该方法是有效、合理的。

According to the battlefield situation and weapon systems＇ characteristics in the air multi-target attacking,a set of improved factors for threat assessment was introduced.Combination determining weights method for TOPSIS was studied,the objective weights were gained by minimizing deviations of weighted membership degree method,and linear weighted method was used to combine objective weights with subjective weights.The rationality of this combination method was also argued mathematically.TOPSIS based on combination determining weights was used to process multi-target threat assessment ultimately.An example indicated that the method is effective and reasonable finally.
