Abstract

In view of the deficiency that target threat assessment based on three-way decision(3WD) model is difficult to completely classified the targets, target threat assessment based on sequential three-way decision(S3WD) model was introduced in this paper. Firstly, the comprehensive information matrix of targets was established under intuitionistic fuzzy environment. Based on the comprehensive information matrix, VIKOR method was used to evaluate the conditional probability and calculate the threshold pair. Besides, two important parameters in VIKOR method with respect to classification effect in S3WD model were systematically analyzed. Finally, the numerical examples show that compared with traditional methods, this method can achieve the dynamic threat assessment by adjusting the threshold pair when attribute is updating, which is more suitable for modern air combat.
