粗糙集的代数分析是粗糙集理论研究的一个重要方向,为了用代数的手段研究粗糙集,将粗糙集理论应用于格蕴涵代数,利用LI-理想诱导的同余关系,引入了格蕴涵代数的上、下粗糙LI-理想的概念,并讨论了粗糙LI-理想的相关性质。
The algebraic analysis is one important research field in rough set theory study.For investigating rough set though algebraic method,rough set theory was applied into lattice implication algebra,and the concepts of upper/lower rough LI-ideals in lattice implication algebra were proposed.Some relative properties of rough LI-ideals were discussed.
