The aim of the paper is to introduce a modified hybrid algorithm to solve a wait-and-see reformulation of transportation optimization model with random demand parameters and 0-1 network design variables. Firstly, the deterministic linear transportation model with network design variables is reviewed. Then, uncertain demand parameters are introduced and modeled by random variables. The following deterministic reformulation is based on the wait-and-see (WS) approach. Finite discrete probability distributions are assumed for all random variables, and hence, the obtained separable scenario-based model can be repeatedly solved as a finite set of mixed integer linear programs (MILPs) by means of integer programming techniques or some heuristics. However, the authors combine a traditional optimization algorithm and a suitable genetic algorithm to obtain a hybrid algorithm that is modified for the WS case. Its implementation and test results illustrated by figures are also discussed in the paper.
