Abstract
Consensus Reaching Process in the Two-Rank Group Decision-Making with Heterogeneous Preference Information
Highlights
Group decision-making (GDM) [1,2] as an important field in decision analysis has gained the increasing attentions since its first appearance
To overcome the weaknesses in the existing consensus reaching process (CRP) with heterogeneous preference structures, the aim of this paper is to develop a novel CRP for the two-rank GDM problems with heterogeneous preference information
The feedback adjustment rules are composed of two key components: (i) Transforming the collective preference vector into the type of preference information expressed by each individual
Summary
Group decision-making (GDM) [1,2] as an important field in decision analysis has gained the increasing attentions since its first appearance. In real applications of GDM problems, due to the differences of the professional knowledge, cultural background, and social experience among different individuals, it is natural that different decision makers may utilize heterogeneous representation structures to express their preferences on the alternatives [3]. Over the last few decades, a mass of consensus models for the GDM with heterogeneous preference structures have been developed from different focuses: (i) Heterogeneous formats of expressions. With the consideration of the individuals may use different scale of linguistic terms to express their preferences, various CRPs with the multi-granularity linguistic term information have been proposed [15,16,17,18,19].
