This paper studies the dual theory of the cone-constrained vector optimization problem with variable ordering structures. The Lagrangian associated with the nonlinear scalar function is defined. The saddle point’s properties of this Lagrangian are discussed, and the properly minimal solution in the sense of Benson is characterized according to the saddle point of the Lagrangian. Furthermore, the corresponding dual set of the given cone-constrained vector optimization problem is defined according to the Lagrangian, and the associated strong dual results are proved under the assumption of stability.
