The concepts of ( )-fuzzy bi-hyperideals and ( )-fuzzy quasi-hyperideals of a semihyperring are introduced, and some related properties of such ( )-fuzzy hyperideals are investigated. In particular, the notions of hyperregular semihyperrings and left duo semihyperrings are given, and their characterizations in terms of hyperideals and ( )-fuzzy hyperideals are studied.
