In this paper, the notation of a strongly ordered congruence on an orderedsemigroup s is introduced.
设s是有向序半群，本文给出了S上的一类正则同余，称为强序同余的定义及性质。

Finally, we characterize regular duo orderedsemigroup s by ordered fuzzy points and fuzzy bi-ideals of s.
最后我们利用序模糊点和模糊双理想对正则舵序半群给出了刻画。

The aim of this paper is to study prime fuzzy I deals of an orderedsemigroup s to characterize prime fuzzy ideals of s by fuzzy points and fuzzy left (right) ideals of s.
