摘要: 将粗糙集理论、逻辑运算与粒度计算进行嫁接,得到了粒度逻辑运算下的粗糙集理论模型。对粒度逻辑运算下的粗糙集进行了形式化的定义,讨论并证明了相关性质。同时,讨论了知识的粗细与基于粒度逻辑运算的粗糙集之间的关系,这为进一步研究基于粒计算的知识获取和粒度推理奠定了逻辑基础。

Abstract: This paper grafts rough set theory,logical computing with granular computing,and retrieves rough set model under logical computing of granules.First it defines rough set model under logical computing of granules formally and then presents its properties.In addition,this paper discusses the coarseness of knowledge with rough set under logical computing of granules.All of these will lay a foundation for knowledge acquisition based on granular computing and granular induction.

Key words: information granule, logical computing, rough set, granular computing
