| Abstract: | In this paper, some necessary and sufficient optimality conditions for the weakly efficient solutions of vector optimization
problems (VOP) with finite equality and inequality constraints are shown by using two kinds of constraints qualifications
in terms of the MP subdifferential due to Ye. A partial calmness and a penalized problem for the (VOP) are introduced and
then the equivalence between the weakly efficient solution of the (VOP) and the local minimum solution of its penalized problem
is proved under the assumption of partial calmness.
