Abstaract−The notions of (λ, µ)-fuzzy ideals, (λ, µ)-fuzzy k-ideals, (λ, µ)-fuzzy k-bi-ideals, (λ, µ)-fuzzy k-quasi-ideals of an ordered Γ-semirings are introduced and some related properties are investigated. The concepts of k-regularity, k-intra-regularity are studied along with some of their characterizations
