摘要
Abstract
In this paper, we mainly discuss the properties of upper approximation operator and lower ap- proximation operator based on graded rough set. Then a new approximation operator which is compared with other definition forms of operators is defined. Finally various kinds of relation to approximation opera- tors are concluded.关键词
