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 …

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 …

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 …

Three-way decisions with decision-theoretic rough sets (DTRSs) as a typical risk decision
method, are generated by Bayesian decision theory and have three kinds of decision …

Practical decision situations are becoming increasingly complicated. It is common for a
person to select or rank alternatives with respect to multiple attributes, and the TODIM (an …

Covering based intuitionistic fuzzy (IF) rough set is a generalization of granular computing
and covering based rough sets. By combining covering based rough sets, IF sets and fuzzy …

Three-way decisions were originally derived from decision-theoretic rough sets (DTRSs). A
fundamental and important problem on DTRSs operating in multiple environments is how to …

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 …

Although the rough set and intuitionistic fuzzy set both capture the same notion, imprecision,
studies on the combination of these two theories are rare. Rule extraction is an important …

Three-way decision model (3WDM) with decision-theoretical rough sets (DTRSs) always
addresses precise cost parameters and precise attribute values in uncertain problem …
