Introducing hesitant fuzzy equations and determining market equilibrium price

Abstract A vast majority of research has been performed in the field hesitant fuzzy sets (HFSs), involving introduction some properties, operations, relations and modifications such or considering application HFSs MCDM (multicriteria decision making). On other hand, no fully equations. Therefore, this paper, equations dual are introduced. First, a method is proposed to solve one-element Then, extended n -element effectively. Moreover, show applicability method, it used real world problem. Thus, applied determine market equilibrium price. Also, numerical examples presented better performance method.
