Abstract. In this paper, using improvement-valued maps, we define two types of -Benson proper efficient elements for subsets within a linear space under a variable ordering map
. Consequently, we delve into studying two types of
-Benson proper efficient solutions of vector optimization problems under variable ordering structures. We establish relationships among different types of
-Benson proper efficient elements. Furthermore, we demonstrate that the two types of
-Benson proper efficiency, in relation to the ordering map
, not only unify and extend certain notions of (weakly) nondominated elements but also extend some well-known notions of Benson proper efficiency under fixed ordering structures. Lastly, under suitable assumptions, we establish linear scalarization theorems for
-Benson proper efficient solutions of vector optimization problems under variable ordering structures. Several examples are also provided to illustrate the derived results.
