In order to effectively portray the uncertainty in the decision making process, a new intervalvalued hesitant fuzzy sets is defined based on the properties of hesitant fuzzy sets and the situation where the evaluation values are interval values. Then, based on the definition of interval-valued hesitant fuzzy sets and basic operations of interval value, some operations and properties of interval-valued hesitant fuzzy element are proposed. At the same time, the relationship between interval-valued hesitant fuzzy sets and other fuzzy sets such as interval-valued fuzzy sets, hesitant fuzzy sets and interval-valued intuitionistic fuzzy sets are illustrated.
