CONSISTENCY OF HESITANT FUZZY PREFERENCE RELATIONS

摘要

In decision making it is necessary to study the consistency of preference relations to make sure that experts do not provide their preferences randomly. The lack of consistency might drive to wrong decisions. Taking into account the importance of checking the consistency in preference relations and the recent use of hesitant fuzzy sets to model the expert's hesitancy in decision making problems, the aim of this contribution is to propose and study definitions of consistency for hesitant fuzzy preference relations.
