The definition of(α,β)-(β,α) type subadditive set-valued map on a cone subset of a vector space with zero was introduced,and theorems of existence and uniqueness of an additive selection for the above map with closed convex values were obtained.The main result generalize and improve the corresponding conclusion in the literature.
