广义三支决策与狭义三支决策
Generalized Three-Way Decisions and Special Three-Way Decisions
摘要
Abstract
With the development and recent research of three-way decisions (3WD), this paper proposes generalized three-way decisions and special three-way decisions based on the models, algorithms and applications of 3WD at first. Generalized three-way decisions focus on illustrating the intension and extension of 3WD;and special three-way deci-sions take attention to the semantic interpretation of 3WD in real decision problems. Then, this paper presents a"four-level"three-way granular structure decision model. In order to clarify the development process and research context of 3WD, this paper uses two viewpoints (static and dynamic viewpoint, generalized and special viewpoint) to analyze 3WD. Finally, this paper gives the research status and future research directions of 3WD.关键词
