摘要
1.引言
粗糙集理论(rough set theory)是波兰Z.Pawlak教授于1982年提出的[1],1991年Z.Pawlak的专著<Rough Sets-Theoretical Aspects of Reasoning about Data>的问世[2],标志着粗糙集理论及研究进入了活跃时期.
Rough implication operator is the emphasis and difficulty in the study of rough logic. Due to the shortage of rough implication in [3]-[5],we redefine rough set and rough implication operator by Stone algebra, and introduce new rough operators such as rough intersection, rough union, and rough complement. Moreover the characteristics of the proposed rough implication are investigated,and we also point out that the proposed implication operation is superior to that of three-valued Lukasiewicz logic.
