摘　　要：针对当前防空作战的目标威胁评估方法对于敌方目标间态势考虑不全、未能较好利用目标动态信息等问题,提出基于作战态势和改进的客观赋权法(criteria importance though intercrieria correlation,CRITIC)和逼近理想解排序法(technique for order preference by similarity to ideal solution,TOPSIS)的目标动态威胁评估模型。首先,在敌我态势指标体系的基础上,提出基于作战环理论的敌方目标间态势威胁指标体系。然后,使用改进的CRITIC确定权重,通过TOPSIS方法计算威胁度。最后,提出基于态势变化程度计算时间权重,通过态势因子加权得到最终评估结果。实验结果表明,基于作战态势和改进CRITIC-TOPSIS的目标威胁评估模型可以综合考虑敌我态势、敌方目标间态势和态势动态信息,对目标做出灵活全面的威胁评估。Aiming at the problems that the current target threat assessment method in air defense operations does not fully consider the situational factors of enemy’s inter-target and cannot make good use of dynamic information,a target dynamic threat assessment model based on the improved criteria importance though intercrieria correlation(CRITIC)and technique for order preference by similarity to ideal solution(TOPSIS)is proposed.Firstly,on the basis of situational index system of enemy targets relative to our side,a situational threat index system between enemy’s inter-target based on the operational loop theory is proposed.Then,the improved CRITIC method is used to determine the weights,and the TOPSIS is used to calculate the threat level.Finally,a time weighting factor is introduced to consider the degree of situational changes in the calculation of time weight,and the final evaluation result is obtained by weighting the situational factors.The experimental results show that the target threat assessment model based on operational situation and improved CRITIC-TOPSIS can comprehensively consider the situation between the enemy and ourside,the situation enemy targets and the dynamic changes,and can make flexible and comprehensive threat evaluation of targets.
