Soft sets have been regarded as a useful mathematical tool to deal with uncertainty. In recent years, many scholars have shown\nan intense interest in soft sets and extended standard soft sets to intuitionistic fuzzy soft sets, interval-valued fuzzy soft sets, and\ngeneralized fuzzy soft sets. In this paper, hesitant fuzzy soft sets are defined by combining fuzzy soft sets with hesitant fuzzy sets. And\nsome operations on hesitant fuzzy soft sets based on Archimedean t-norm and Archimedean t-conorm are defined. Besides, four\naggregation operations, such as the HFSWA, HFSWG, GHFSWA, and GHFSWG operators, are given. Based on these operators,\na multicriteria group decision making approach with hesitant fuzzy soft sets is also proposed. To demonstrate its accuracy and\napplicability, this approach is finally employed to calculate a numerical example.
