基于随机多权重TOPSIS法的目标威胁评估

Target threat assessment based on random multi-weights TOPSIS method

在目标威胁评估问题中,为了解决目标各项特征权重选取可能存在主观决策误差的问题,提出了一种基于随机多权重TOPSIS法的空中目标威胁评估方法。基于层次分析法确定了各项特征之间的权重,对难以定量衡量的目标特性进行了特征提取,并基于随机多权重TOPSIS法将空中目标的威胁度进行了评估。仿真实例表明:随机多权重TOPSIS法威胁评估与AHP、TOPSIS方法排序一致,但给出了各目标威胁度的不确定范围,实验中不确定范围值最低为0.08%,最高为3.78%。战场指挥人员可以通过本文中提出的威胁度不确定性范围得到更多参考信息。

In the problem of target threat assessment,in order to solve the shortcomings of possible subjective decision-making errors in the selection of weights of various characteristics of the target,an air target threat assessment method based on the random multi-weight TOPSIS method is proposed.This paper determines the weights between various features based on the analytic hierarchy process,extracts features of target characteristics that are difficult to quantitatively measure,and evaluates the threat of air targets based on the random multi-weighted TOPSIS method.The simulation results show that the threat assessment ranking of the random multi-weighted TOPSIS method is consistent with the AHP and TOPSIS methods,but the uncertainty range of each target’s threat degree is given.The lowest uncertainty range value in the experiment is 0.08%and the highest is 3.78%.Combat commanders can obtain more reference information through the threat uncertainty range proposed in this article.
