Let S be an ordered semigroup. In this paper we first introduce the concepts of ∈, ∈ ∨ qk-fuzzy ideals, ∈, ∈ ∨ qk-fuzzy bi-ideals and ∈, ∈ ∨ qk-fuzzy generalized bi-ideals of an ordered semigroup S by the ordered fuzzy points of S, and investigate their related properties. Furthermore, characterizations of regular ordered semigroups by the properties of ∈, ∈ ∨ qk-fuzzy left ideals, ∈, ∈ ∨ qk-fuzzy right ideals and ∈, ∈ ∨ qk-fuzzy generalized bi-ideals are given.
