The best consistency index (BCI) and the worst consistency index (WCI) were introduced
into interval additive preference relations (IAPRs) to guarantee that any APR within an IAPR …

This paper investigates a group decision making (GDM) method with interval valued fuzzy
preference relations (IVFPRs). According to the geometric consistency of IVFPR, the max …

This paper focuses on heterogeneous group decision making (GDM) in the setting of
incomplete preference relations, including incomplete fuzzy preference relations, incomplete …

To examine the multiplicative consistency of interval fuzzy preference relations (IFPRs), this
paper first analyzes the limitations associated with the previous consistency concepts …

The interval cross-efficiency approach is an effective technique to rank decision making
units (DMUs). It somewhat alleviates the selection difficulties between benevolent and …

Intuitionistic multiplicative preference relation (IMPR) has been successfully and widely used
to model the decision makers' preferences elicited by pairwise comparisons. As the critical …

Interval-valued fuzzy preference relations (IVFPRs) have been applied to many real-life
decision-making problems. However, most definitions of consistency of IVFPRs do not …

Many group decision making (GDM) models enable experts to use only one preference
information representation form. It is natural to allow experts to express preferences in …

This paper focuses on answering the following question: How to estimate the quality of off-
diagonal judgments in an interval multiplicative preference relation (IMPR) and obtain an …

In large-scale group decision-making (LSGDM), incomplete preferences often arise due to
the complexity of LSGDM or the limited experience of decision-makers (DMs). When DMs …
