Approach of linguistic group decision making based on combination weighting 2-tuple linguistic VIKOR

Abstract

This paper presented an approach of linguistic group decision-making based on combination weighting 2-tuple linguistic VIKOR. Firstly, the 2-tuple linguistic is used to cope with assessment information of attribute values and weights that represented with linguistic variable. Subjective weights of attribute are calculated by using the weighted averaging operator for 2-tuple linguistic and the objective weights of attribute are determined based on the statistical variance. And subjective weight and objective weight are integrated into combination weight. Then, through the 2-tuple linguistic VIKOR method, the compromise ranking result of alternatives can be determined. Finally, an example analysis is given to illustrate the validity and applicability of the proposed method.
