摘要
以不完备信息系统为研究对象,提出了基于邻域容差关系的乐观多粒度粗糙集和悲观多粒度粗糙集模型,它融合了邻域粗糙集与多粒度粗糙集的方法,亦称为邻域多粒度粗糙集.进一步,对邻域多粒度粗糙集的基本性质进行了讨论,这为采用粗糙集方法处理不完备信息系统提供了新的技术手段.
In the incomplete information system,the neighborhood rough sets and multigranulation rough sets methods are combined.Based on neighborhood tolerance relation is constructed of optimistic and pessimisticmultigranulation rough sets models,which are also called neighborhood multigranulation rough sets.Furthermore,we discuss the basic properties of neighborhood multigranulation rough sets,which provide a new technical means for using rough set method to deal with incomplete information system.
