摘　　要：针对传统多目标威胁评估方法通常是二支决策,只能得到目标威胁排序,需要主观地划定威胁等级与选择作战目标数,不适应于复杂动态任务环境的问题,提出直觉模糊信息下基于VIKOR和三支决策的多目标威胁评估方法.首先,对动态直觉模糊威胁评估信息进行集结并求取属性权重;然后,通过VIKOR方法求取目标决策所需的条件概率;最后,通过评估信息构造各属性下目标的损失函数矩阵,集结得到目标的综合损失函数矩阵,计算综合阈值,得到决策规则.算例分析表明,所提方法能够有效地处理动态不确定目标态势信息,将传统方法的二支排序结果转变为三支分类结果;可以依据目标态势信息客观地选取作战目标.The traditional multi-target threat assessment methods are usually two-way decisions,can only obtain the threat ranking of targets,and need to subjectively determine the threat level and select the number of combat targets,which is not suitable for the complex dynamic mission environment.This paper proposes a multi-target threat assessment method based on VIKOR and three-way decisions under intuitionistic fuzzy information.Firstly,the dynamic intuitionistic fuzzy threat information is aggregated and attribute weights are obtained.Then,the conditional probability of targets for decision making is obtained by VIKOR method.Finally,the loss function matrices of targets under each attribute are constructed by attribute information,the comprehensive loss function matrix is obtained after aggregation and the comprehensive thresholds and decision rules are obtained.The case studies show that the proposed method can effectively deal with the dynamic uncertain situation information,transform the ranking results of two-way decisions into classification results of three-way decisions,and can objectively select the combat targets via situation information.
