Abstract

The uncertain group decision-making (UGDM) methodology has developed rapidly in recent years, which is synchronous with the evolution of fuzzy set (FS) theory and linguistic term set theory. Generally, the UGDM methods can be divided into three categories, i.e., the multi-attribute decision-making (MADM) methods, the preference-based methods and the dynamic decision-making methods. In this paper, we present an overview on UGDM, including the methodology, framework and recent development of the methods. These methods are classified into different types according to their features and calculation processes. Also, we connect the recent decision-making methods with the development of FS theory, linguistic term set theory and their extensions, etc. We can find that the development of UGDM methodology and the evolution of information expressions interactively influence and promote each other’s progress. This paper integrates the recent development and provides a framework containing different aspects of uncertain decision-making methods.
