基于熵权-TOPSIS-灰色关联的目标威胁评估研究

Target Threat Evaluation Based on Entropy Weight-TOPSIS-Grey Correlation

针对空战目标威胁评估问题进行研究,建立了基于熵权-TOPSIS-灰色关联方法的威胁评估模型。首先利用熵权法确定评估指标的客观权重,其次利用TOPSIS法确定目标与理想解和负理想解的欧氏距离;利用灰色关联法确定目标的关联度,据此计算威胁源的相对贴近程度,并对威胁目标进行评估排序。最后通过实例对建立的模型进行了仿真验证,结果表明,该方法综合运用TOPSIS和灰色关联法,使得目标威胁评估结果更加合理有效。

Aiming at threat evaluation for targets during air combats, a model based on entropy weight-TOPSIS（technique for order preference by similarity to solution）-grey correlation is established. The entropy weight method is used to identify the reasonable amount for evaluation parameters in the beginning. Then it goes on with the TOPSIS method to calculate the Euclidean distance between the target and the ideal and negative solutions. The grey correlation method is also used to judge the relations between the targets. Based on these, the comparative close degree will be calculated to evaluate and rank the threat targets. Simulation result shows that the method takes the advantage of both TOPSIS and grey correlation method and achieves more reasonable and effective evaluation on threat targets.
