Preference reliability analysis for preference relations reflected by the ordinal consistency
and the cardinal consistency was intensively studied. The ordinal consistency is a minimum …

This paper proposes an optimal consensus model to derive weights for linguistic preference
relations (LPRs). Two indexes, an individual‐to‐group consensus index (ICI) and a …

Preference ordering structures are useful and popular tools to represent experts'
preferences in the decision making process. In the existing preference orderings, they lack …

For group decision making with incomplete linguistic preference relations, this paper first
make an analysis about individual consistency, based on which a goal programming model …

We establish in this paper the optimization model of group consensus of 2-tuple linguistic
preferential relations (LPRGCO Model), put forward three kinds of solutions to this model …

This paper studies the group decision making problem with linguistic preference relations.
We first study the consensus measure between the individual preference relations and the …

In group decision making (GDM) situations, it is quite natural that the decision makers who
may have different background and knowledge will provide their preferences by means of …

The probabilistic linguistic preference relation (PLPR) reflects different preference degrees
(or weights) of experts over possible linguistic terms and improves the flexibility for experts in …

Preference relation has been one of the most useful tools for experts to express their
comparison information over alternatives in group decision‐making (GDM) problems …

Owing to the important role in group decision making (GDM), the consensus research has
received extensive attention from both theoretical and applied perspectives in recent years …
