摘要
基于双向S-粗集和一般二元关系,提出广义双向S-粗集,对广义双向S-粗集的一般结构进行了描述,对广义双向S-粗集的有关性质进行了讨论,并给出了具体实例和意义解释。广义双向S-粗集为研究一般系统动态的近似特性提供了新的途径和方法。
Based on two-direction singular rough sets and general binary relation, this article puts forward the model of generalized two-direction singular rough sets and briefly describes its general structures. It follows to discuss the relevant nature of generalized two-direction singular rough sets with specific examples and significance interpretation. It is hold that the modol provides the new way and method for the research of general system dynamical approximations.
