Many models and methods have been developed to determine numerical thresholds in
three-way decision. However, there are challenges such as local optimum-based …

In this paper, we investigate hybrid multiple attribute decision making problems with various
forms of attribute values (real numbers, linguistic labels, interval numbers, intuitionistic fuzzy …

Preference relations as information representation form are widely used to manage
complexity and uncertainty in practical decision-making cases. Intuitionistic trapezoidal fuzzy …

The determination of both thresholds in decision-theoretic rough sets is an important
problem of study that has aroused widespread attention in recent years. Although many …

Problems with qualitative, quantitative and uncertain information can be modelled better
using trapezoidal intutionistic fuzzy numbers (TrIFNs) than fuzzy numbers. Due to the partial …

Faced with any decision-making problems with fuzzy multicriteria information, decision-
makers generally set a minimum requirement on each criterion for satisfying their own …

In order to use three-way decision (TWD) to solve multiple attribute decision making (MADM)
problems, in this article, a new TWD model with intuitionistic fuzzy numbers (IFNs) is …

Triangular intuitionistic fuzzy numbers (TIFNs) is one of the useful tools to manage the
fuzziness and vagueness in expressing decision data and solving decision making …

Triangular fuzzy preference relations (TFPRs) have long been viewed as an effective
framework to express subjective preferences with ambiguity in fuzzy multicriteria decision …

When using linguistic approaches to solve decision problems, we need the techniques for
computing with words (CW). Together with the 2-tuple fuzzy linguistic representation models …
