基于区间数TOPSIS法的空战目标威胁评估

Threat assessment for air combat target based on interval TOPSIS

针对空战目标威胁评估问题,提出了一种新的基于区间数TOPSIS法的评估方法。在分析了现有的目标威胁评估方法中距离威胁模型存在不足的基础上,提出了改进的距离威胁模型。给出了区间数特征向量法求解威胁指标权重的计算步骤,克服以往威胁指标权重确定方法的不足,建立了区间数TOPSIS法评估目标威胁的数学模型。给出了仿真算例,仿真结果表明该方法是合理和有效的。

A new assessment method based on intervals TOPSIS is proposed with regard to the problem of threat assessment for air combat targets. An improved model is proposed based on analyzing the existing target threat assessment methods which has deficiency in the distance threat model. The calculation steps for solving the weights of threat indexes by using the interval-number eigenvector method is given, which conquered the flaw of fomer methods for ascertaining weights of threat indexes. Then the mathematical model for evaluating target threat by intervals TOPSIS is established. Finally, an application example is given and the results show that the method is reasonable and effective.
