In this paper, we define and develop several operation laws for hesitant fuzzy elements based on the Archimedean t-conorm and t-norm. The developed operators provide a family of hesitant fuzzy aggregation operators that include the existing hesitant fuzzy aggregation operators based on the Algebraic, Einstein, and Hamacher t-conorms and t-norms as special cases. Moreover, we study the operators??? properties and relationships and provide several specific hesitant fuzzy aggregation operators, which can be considered to be the extensions of the known operators. Finally, we apply the developed operators to present an approach for multi-criteria decision making with hesitant fuzzy information and provide a numerical example to illustrate the developed operators and approach.
