A rational consensus model in group decision making using linguistic assessments
نویسندگان
چکیده
A new consensus model for the consensus reaching process, in a linguistic framework, is presented in heterogeneous group decision making problems, called rational consensus model. It is guided by some linguistic consensus and linguistic consistency meaures. All the measures are calculated from a set of linguistic preference relations used to provide experts' opinions. This consensus model allows more rational consensus solutions to be obtained and thus, more human consistency to be incorporated in decision support systems. @ 1997 Elsevier Science B.V.

A model of consensus in group decision making under linguistic assessments
This paper presents a consensus model in group decision making under linguistic assessments. It is based on the use of linguistic preferences to provide individuals' opinions, and on the use of fuzzy majority of consensus, represented by means of a linguistic quantifier. Several linguistic consensus degrees and linguistic distances are defined, acting on three levels. The consensus degrees indi...

متن کاملA Consensus Model for Group Decision Making Problems with Unbalanced Fuzzy Linguistic Information
Most group decision making (GDM) problems based on linguistic approaches use symmetrically and uniformly distributed linguistic term sets to express experts’ opinions. However, there exist problems whose assessments need to be represented by means of unbalanced linguistic term sets, i.e. using term sets that are not uniformly and symmetrically distributed. The aim of this paper is to present a ...
متن کاملManaging the consensus in group decision making in an unbalanced fuzzy linguistic context with incomplete information
To solve group decision-making problems we have to take in account different aspects. On the one hand, depending on the problem, we can deal with different types of information. In this way, most group decision-making problems based on linguistic approaches use symmetrically and uniformly distributed linguistic term sets to express experts’ opinions. However, there exist problems whose assessme...

Group decision-making is an essential activity is many domains such as financial, engineering, and medical fields. Group decision-making basically solicits opinions from experts and combines these judgments into a coherent group decision. Experts typically express their opinion in many different formats belonging to two categories: quantitative evaluations and qualitative ones. Many times exper...
