| Abstract: |
| Based on the concept of rough sets, this paper discusses the relationship between rough ideal and rough direct product in congruence relation, gets some good properties theorem, and further enriches and improves the rough set theory in semigroups. |
| Key words: semigroups congruence relation rough direct product rough ideal |
