Abstract
A typical minimax model of stochastic programming can be described as minimizeT∈T,supH∈H EHf (T, ξ). Here T is a vector of decision variables, restricted to a fixed feasible set T ⊂ ℝ N. The function f to be minimized depends not only on T but also on the unknown realization of an n-dimensional random vector ξ. For that reason the expected value of f is chosen as the objective function. However, the distribution function H of ξ is not completely known to the decision maker: it may be any element of a family H of distribution functions. The supremization in the “inner problem” indicates that a worst-case approach is adopted: the decision on T in the “outer problem” is based on the most unfavorable distributions in H
