基于Vague集的空中目标威胁评估群决策方法

主观威胁评估方法是空中目标威胁评估的必要手段。将基于Vague集的群决策方法用于空中目标的主观威胁评估，用Vague数表示决策者对目标威胁度的主观评价值，提出一种Vague熵诱导的有序加权平均算子，用于集结各个Vague评价值，可以消除集结过程中人为误差带来的不良影响。为了直观评估各目标威胁程度大小，还提出一种基于Vague数距离和优劣点法的决策方法，来对目标威胁度进行比较和排序。算例证明该方法在空中目标威胁评估中是可行的，而且比常用的模糊综合评估方法更加有效。

Group decision-making method for air target threat assessment based on Vague sets

Subjective threat evaluation is necessary for air target threat assessment.A group decision-making method based on Vague sets is used to accomplish this evaluation.Vague values are used to express the decision-maker's uncertainty subjective preference in the air target threat assessment,and a Vague entropy induced ordered weighted averaging(VE-IOWA) operator is proposed to synthesize these Vague values,which can eliminate the harmful uncertainty man-made accidents in the process.Then a decision method based...
