The primary purpose of this paper was based on the notion of bi-Γ-hyperideal generated by non-empty subsets of an ordered Γ-semihypergroups. The notion of bi-bases on was introduced and the quasi-order was defined by the principal of bi-Γ-hyperideal. Moreover, a non-empty subset was a bi-base and it was characterized. The results were obtained by extending the concept on Γ-semigroup.
