摘要
基于函数S-粗集区间属性,定义了区间等价类和区间函数S-粗集,并给出了闭区间等价类有限覆盖定理及闭区间函数S-粗集的有限覆盖定理,从理论上证明了函数S-粗集与S-粗集之间的关系.
Interval equivalence classes and interval function S-rough Sets are defined based on interval attribute of function S-rough sets, and the finite covering theorem d closed interval equivalence classes and that d closed interval function S-rough sets are put forwant. The relation d function S-rough sets and S-rough sets is also theoretically proved.
