Three-way decisions with decision-theoretic rough sets (DTRSs) provide a new
methodology to confront risk decision problems. The risk is associated with the loss function …

Decision-theoretic rough set provides a new perspective to handle decision-making
problems under uncertainty and risk. The three-way decision theory proposed by Yao is …

In an uncertain and complex decision-making environment, limited by the scope of human
cognition, traditional utility decision-making has a certain deviation to actual decision …

In three-way decision, how to reflect the risk attitude in determining decision rules is an
important issue. In the classical three-way decision model, loss functions are used to …

In this paper, a novel concept formation and novel concept lattices are developed with
respect to a binary information table to support three-way decisions. The three-way …

This study is concerned with the design of a three-way classification mechanism realized
through combing fuzzy decision trees and expressing uncertainty associated with …

This paper investigates the decision-theoretic rough sets involved multiple decision-makers
with linguistic evaluation information for the uncertainty and risk under the framework of …

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 …

In classical rough set models, attribute reduction generally keeps the positive or non-
negative regions unchanged, as these regions do not decrease with the addition of …

Three-way group decision-making is an important direction of study in the fields of three-way
decision-making and granular computing and has received much attention from scholars in …
