This work studies the aggregation operators on the set of all possible membership degrees of typical hesitant fuzzy sets, which we refer to as HH, as well as the action of HH-automorphisms which are defined over the set of all finite non-empty subsets of the unitary interval. In order to do so, the partial order ⩽H⩽H, based on α -normalization, is introduced, leading to a comparison based on selecting the greatest membership degrees of the related fuzzy sets. Additionally, the idea of interval representation is extended to the context of typical hesitant aggregation functions named as the HH-representation. As main contribution, we consider the class of finite hesitant triangular norms, studying their properties and analyzing the HH-conjugate functions over such operators.
