The purpose of this paper is to consider the set‐valued optimization problem in Asplund spaces without convexity assumption. By a scalarization function introduced by Tammer and Weidner (1990), we obtain the Lagrangian condition for approximate solutions on set‐valued optimization problems in terms of the Mordukhovich coderivative.
