In this paper, we investigate group decision making problems with multiple types of linguistic
preference relations. The paper has two parts with similar structures. In the first part, we …

To better deal with imprecise and uncertain information in decision making, the definition of
linguistic intuitionistic fuzzy sets (LIFSs) is introduced, which is characterized by a linguistic …

A large-scale group decision-making (LGDM) problem is studied from the perspective of
multi-stage hesitant fuzzy linguistic term sets (MHFLTSs). Solving an LGDM problem …

A game is a situation which conceives and concludes through reality involving a set of
players, may be two or more. Conclusions of such situations are not always very easy, eg, if …

In this paper, we propose a linguistic hybrid arithmetic averaging (LHAA) operator, which is
based on linguistic weighted arithmetic averaging (LWAA) operator and extended ordered …

Large-scale group decision-making (LSGDM) is characterised by a large number of experts
and a complex consensus reaching process. Clustering is used to divide the large group …

Supply chain sustainability management is gaining increasing importance. Several studies
propose quantitative evaluation approaches to manage sustainable supply chains …

Rough set theory has become an effective tool to address uncertain decision-making
problems. Nevertheless, existing rough set-based decision-making methods cannot …

Herrera and Martínez initiated a 2-tuple fuzzy linguistic representation model for computing
with words. Moreover, Wang and Hao further developed a new 2-tuple fuzzy linguistic …

In this work, we consider the problem of consensus of multiple attribute group decision
making, and develop an automatic approach to reaching consensus among group opinions …
