| Abstract: | 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. |

| Keywords: | function S-rough sets closed(open)interval equivalence classes closed(open)function S-rough sets finite covering theorem |
