In the domain of Computing with words (CW), fuzzy linguistic approaches are known to be relevant in many decision-making problems. Indeed, they allow us to model the human reasoning in replacing words, assessments, preferences, choices, wishes. . . by ad hoc variables, such as fuzzy sets or more sophisticated variables. This paper focuses on a particular model: Herrera & Mart́ınez’ 2-tuple lingu...

Emergency management (EM) is a very important issue with various kinds of emergency events frequently taking place. One of the most important components of EM is to evaluate the emergency response capacity (ERC) of emergency department or emergency alternative. Because of time pressure, lack of experience and data, experts often evaluate the importance and the ratings of qualitative criteria in...

The linguistic terms used to describe the qualitative data in problems are symmetrical about central word. With increasing complexity and a large number of DMs with different domain expertise involved decision-making, symmetric term set seems constricted. This paper examines multiple-criteria group decision-making which decision-makers use unbalanced 2-tuple alternative–criteria assessments mat...
