A survey of approaches to decision making with intuitionistic fuzzy preference relations

Intuitionistic fuzzy preference relations (IFPRs) have attracted more and more scholars' attentions in recent years due to their efficiency in representing experts' imprecise cognitions. With IFPRs, people can express their opinions over different pairs of alternatives from positive, negative and hesitative points of view. This paper presents a comprehensive survey on decision making with IFPRs with the aim of providing a clear perspective on the originality, the consistency, the prioritization, and the consensus of IFPRs. Finally, some directions for future research are pointed out. (C) 2015 Elsevier B.V. All rights reserved.
