Abstract

This paper considers vector optimization problems via co-radiant sets and studies the existence conditions of the Benson weakly efficient solutions of these problems. Firstly, the properties of radiant sets and co-radiant sets were discussed. Then, models of vector optimization problems via co-radiant sets and their Benson weakly efficient solutions were proposed. Finally, using the linear scalarization method, sufficient conditions for these Benson weakly efficient solutions are formulated.

Keywords: Vector optimization problem, Benson weakly efficient solution, existence, radiant set, co-radiant set.
