Abstract: In ordered linear spaces，generalized vector Fritz-John saddle point and generalized vector Kuhn-Tucker saddle pojnt of set-valued optimization problems with generalized inequality constraints were defined，and the relations between them were established.And then，applying the alternative theorems under the generalized cone-subconvexlikeness，the relations among the weak efficient solutions of set-valued optimization problems and them were dicussed.

Key words: set-valued optimization, ordered linear spaces, generalized Y+-subconvexlikeness, generalized vector Fritz-John saddle point, generalized vector Kuhn-Tucker saddle point．

摘要： 在序线性空间中定义了带广义不等式约束集值优化问题的广义向量Fritz-John鞍点和广义向量Kuhn-Tucker 鞍点，建立了二者之间关系．最后，借助广义锥次似凸映射的择一定理，讨论了集值优化问题的弱有效解与它们之问 的关系．
