Group decision making is a common and crucial human activity, where two or more specialists handle complex decision problems, involving conflicting and non-measurable attributes. Thus, new decision-making approaches have been proposed in order to deal with different types of imprecisions. The Dual Hesitant Fuzzy Sets (DHFS) is a recent approach that stands out in the literature due to its ability to combine the advantages of Hesitant Fuzzy Sets and Intuitionistic Fuzzy Sets representations, allowing different types of hesitations by the decision makers. However, no paper has been identified that seeks to conduct a literature review on this theme. Therefore, the purpose of this paper is to present the results of a systematic literature review to assess the state of the art of DHFS. In addition, current applications are presented, and opportunities for future studies are elucidated.
