Rough set model under logical computing of granules

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.
