In this paper,we derive a general vector Ekeland variational principle for set-valued mappings,which has a closed relation to εk^O-efficient points of set-valued optimization problems.The main result presentedin this paper is a generalization of the corresponding result in[3].
In this paper, relations between vector and weak vector variational inequalities and equilibrium principles for multiclass, multicriteria traffic network equilibrium problem in the fixed demand case and elastic demand case are established, respectively.
