The concept of interval‐valued Pythagorean fuzzy (IVPF) sets is capable of handling
imprecise and ambiguous information and managing complex uncertainty in real‐world …

An outranking method for duplex linguistic multi-criteria decisions is presented. We define a
duplex linguistic set that is especially suitable for describing a decision-maker's preference …

Preference relations could be originated from a decision making problem by pairwisely
comparing a finite set of alternatives. In order to find an optimal solution, a feasible approach …

Three-way decisions provide a trisecting-and-acting framework for complex problem solving.
For a cost-sensitive decision-making problem under multiple levels of granularity, sequential …

One of the key issues for support fuzzy decision-making is fuzzy number ranking. The
existing ranking methods either do not provide a total ordering or cannot be effectively …

Due to the effectiveness and advantages of interval-valued intuitionistic fuzzy sets (IVIFSs) in
evaluating uncertainty and risk, we introduce IVIFSs into loss functions of decision-theoretic …

Triangular fuzzy preference relation (TFPR) is an effective framework to model pairwise
estimations with imprecision and vagueness. In order to obtain a reliable and rational …

In this paper, we propose a novel multiple attribute decision making (MADM) method based
on the proposed nonlinear programming (NLP) model, the distance between the score …

In this paper, a new method of ranking trapezoidal intuitionistic fuzzy numbers has been
introduced based on the concept of value and ambiguity at different levels of decision …

Interval type-2 trapezoidal fuzzy sets, as a particular form of interval type-2 fuzzy sets, can
precisely characterize the subjective assessments and qualitative evaluations of a group of …
