A HYBRID PARAMETRIC STOCHASTIC PROGRAMMING APPROACH FOR MIXED-INTEGERLINEAR-PROBLEMS UNDER UNCERTAINTY/

In this paper, a novel hybrid parametric/stochastic approach for the s olution of stochastic mixed-integer problems is introduced. The approa ch, based on a two-stage stochastic programming framework recently pro posed by the authors, effectively avoids the repetitive solution of th e second-stage subproblems by solving instead multiparametric programs , resulting in a much more efficient evaluation of the expected value. The approach is detailed with two example problems in which computati onal issues are also discussed.
