The Distance of Hesitant Interval-valued Fuzzy Sets and its Application in Multi-criteria Decision Making

In this paper, some operations of hesitant interval-valued fuzzy sets are introduced. Then the corresponding distance measures between two hesitant interval-valued fuzzy numbers is developed, which obtained motivating by the distance for discrete sets, and s ome desirable properties are examined in detail. Furthermore, an approach to multi-criteria decision making with hesitant interval-valued fuzzy information is proposed. Finally, an application of the proposed method is shown to demonstrate its practicality and effectiveness, and the results are compared by utilizing the other existing method.
