In order to scientifically and accurately evaluate the operational efficiency of the terminal area, consider the operation process and characteristics of the terminal area control system, and establish an evaluation index system for the operation efficiency of the terminal area control system. The triangular weight method and the entropy weight method are used to obtain the subjective weight and objective weight of each index respectively, and the minimum relative information entropy method is used to obtain the combined weight of the two weights. Based on VIKOR method, the terminal area control operation efficiency evaluation model is constructed, the terminal area control operation efficiency index value is calculated, the terminal area control system is evaluated according to the operation efficiency index value, and the evaluation result is compared with the gray correlation TOPSIS method. In contrast, the rationality of the evaluation model is verified.
