A Framework of Group Decision Making with Hesitant Fuzzy Preference Relations Based on Multiplicative Consistency

摘要: The purpose of this paper is to develop a general framework group decision making with hesitant fuzzy preference relations based on the multiplicative consistency. First, we define consistency index measure whether or not relation acceptably A improving process developed improve level unacceptably until it multiplicative. Then, present consensus deviation between individual and their collective relation. reaching help makers among they meet predefined level. Subsequently, establish complete relations. In framework, are simultaneously highlighted each still maintained in achievement Finally, an illustrative numerical example given verify effectiveness practicality method.
