在阐释粗糙集理论基本体系结构的基础上,从多个角度探讨粗糙集模型的研究思路,分析粗糙集理论与模糊集、证据理论、粒计算、形式概念分析、知识空间等其它理论之间的联系,介绍国内外关于粗糙集理论研究的主要方向和发展状况,讨论当前粗糙集理论研究的热点研究领域以及将来需要重点研究的主要问题.
This paper presents a framework for a systematic study of the rough set theory. Various views and interpretations of the theory and different approaches to study the theory are discussed. The relationships between the rough sets and other theories, such as fuzzy sets, evidence theory, granular computing, formal concept analysis, knowledge spaces, etc. , are examined. The paper also reviews recent theoretic studies and applications of rough sets and points out future research directions.
