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 …

In contrast to two-way decisions (2WD), three-way decisions (3WD) can effectively reduce
decision risks by utilizing a new delayed decision option. This article incorporates 3WD into …

A theory of three-way decision is about thinking, problem-solving, and computing in threes
or through triads. In this paper, we review fifteen years of research on three-way decision by …

The realization of the Web as a common platform, medium, and interface for supporting
human activities has attracted many researchers to the study of Web-based support systems …

A fundamental notion of granular computing is a multilevel granular structure in which
different levels are characterized by different degrees of abstraction and details. By making …

Based on the notion of information and knowledge granularity, sequential three-way
decisions can be interpreted and implemented as a multilevel trisecting-and-acting …

Decision-theoretic rough sets (DTRSs) as a classic model of three-way decisions have been
widely applied in the area of risk decision-making. When we confront the complicated and …

In rough set theory, a decision class (ie, a subset of objects) is approximated by three pair-
wise disjoint positive, boundary, and negative regions. The concept of three-way decisions …

The current single granularity-based static prediction approaches face difficulties in
capturing the dynamic trend of stock markets by the fusion of historical prices and streaming …
