In real-world decision problems, decision makers usually express their opinions with
different preference structures. In order to deal with the heterogeneous preference …

Interval type-2 fuzzy sets are useful and valuable for depicting uncertainty and managing
imprecision in decision information. In particular, interval type-2 trapezoidal fuzzy numbers …

A key step in group decision making (GDM) with linguistic preference relations (LPRs) is to
derive the priority weight vector of the alternatives. However, the lack of consistency in GDM …

Multiple criteria decision aiding aims to recommend decisions that are consistent with the
decision-maker's value system by making trade-offs among multiple criteria to measure the …

This study presents a novel minimum deviation ordinal consensus model (MDOCM) for
group decision making with heterogeneous preference structures (utility values, preference …

Multiplicative preference relations (MPRs) are broadly employed in the Analytic Hierarchy
Process (AHP) to support group decision making (GDM). In AHP-GDM, aggregation of …

Existing decision making methodologies like the Analytic Hierarchy Process (AHP) address
imprecise pairwise comparisons by modeling crisp pairwise comparisons as fuzzy sets or a …

Uncertainty is a common phenomenon in our real world. Interval utility values and interval
preference orderings are two of the simplest and most convenient tools to describe uncertain …

The priority weight vectors of an intuitionistic fuzzy preference relation (IFPR) with linear
uncertainty distribution characteristics in group decision making (GDM) are determined in …

The hesitant multiplicative elements (HMEs) are useful tool to address situations in which
the decision makers (DMs) are hesitant about several possible multiplicative values …
