英文摘要：

In this paper,we introduce a new concept of generalized quasi-approximate,solution for set-valued optimization problems,intend to unify the other approximate solutions mentioned in this paper.Further,we study some properties of generalized quasi-approximate solution and obtain the existence theory for generalized quasi-approximate efficient solution.
