Abstract. In this paper, based on the oriented distance function of Hiriart-Urruty, we investigate a set scalarization function of sup-inf type. Some properties of the set scalarization function allow us to define the Dini directional derivatives for set-valued mappings, which is an extension of the classical Dini derivatives for scalar functions. We also obtain some properties of the Dini directional derivatives for set-valued mappings. As applications, we derive some necessary and sufficient optimality conditions for set optimization problems.
