Group Decision Making with Comparative Linguistic Terms
In group decision making (GDM) framework, we focus on decision problems defined under uncertainty where decision makers can hesitate among several values to elicit their preferences. In such cases, the use of hesitant fuzzy linguistic term sets (HFLTS) can facilitate the elicitation of decision makers preferences. In this contribution, our aim is to propose a linguistic GDM model that allows to decision makers use single linguistic terms or comparative linguistic terms to express their preferences and obtain the solution set of alternatives of the GDM problem.
