A decision analysis method based on group integrative dominance degree matrix, the priority-time based method is introduced to rank alternatives and a practical example verifies the feasibility and effectiveness of the proposed method.

Abstract

With respect to multiple attribute group decision-making problems with multi-granularity uncertain linguistic assessment information,a decision analysis method is proposed. First,the description and the property of dominance degree on pairwise comparisons of uncertain linguistic terms are given. Then,according to the dominance degrees,attribute weight vector and expert weight vector,a group integrative dominance degree matrix between pairwise comparisons of alternatives is built by using simple additive weighting method. Furthermore,based on group integrative dominance degree matrix,the priority-time based method is introduced to rank alternatives. Finally,a practical example verifies the feasibility and effectiveness of the proposed method.
