Aim To study the cone subdifferential of the cone efficient solution sets for set valued vector optimization problem with perturbed order. Methods The theories of topology
convex analysis and functional analysis are used to study and analyze some properties of the set valued function in the problem. Results The sufficient conditions of cone subdifferential and weak cone subdifferential for cone efficient solutions set and weak cone efficient solutions set of the problem are obtained. Conclusion The theory of vector optimization is complemented.
