| Abstract: | With the developments of three historical stages on three-way decisions (3WD), this paper introduces the development track and evolution process of 3WD. Firstly, the historical context, internal connections and relations between 3WD and rough sets are carefully investigated. The inclusion relation among decision-theoretic rough sets, probabilistic rough sets, rough sets and 3WD is also discussed. Secondly, we discuss the methodology of 3WD via granular computing with two strategies of “multi-level” and “multi-view”. Thirdly, we propose a novel framework model of granular computing with 3WD. Finally, this paper gives the research status and future research directions of 3WD. |
