After probability theory, fuzzy set theory and evidence theory, rough set theory is a new
mathematical tool for dealing with vague, imprecise, inconsistent and uncertain knowledge …

Rough set theory is an efficient tool for dealing with inexact and uncertain information.
Numerous studies have focused on rough set theory and associated methodologies, and in …

Abstract Three-way decisions (3WD) is an important methodology in solving problems with
uncertainty. A systematic analysis on three-way based uncertainty measures is conducive to …

The key strategy of the three-way decisions theory is to consider a decision-making problem
as a ternary classification one (ie acceptance, rejection and non-commitment). Recently, this …

Pythagorean fuzzy sets (PFSs) as a new generalization of intuitionistic fuzzy sets (IFSs) can
effectively handle uncertain information more flexibly in the process of decision making. As a …

A trisecting-and-acting model explains three-way decisions (3WD) in terms of two basic
tasks. One task is to divide a universal set into three pair-wise disjoint regions called a …

In realistic decision-making environments, human behaviors bring influences to various
decision-making procedures, and classic multiattribute decision-making approaches based …

The existing multiattribute decision-making (MADM) methods on multiscale information
systems (MSISs) are generally studied from the utility point of view, which may cause two …

The rough set theory approximates a concept by three regions, namely, the positive,
boundary and negative regions. Rules constructed from the three regions are associated …

A theory of three-way decisions is constructed based on the notions of acceptance, rejection
and noncommitment. It is an extension of the commonly used binary-decision model with an …
