Original Abstract

The aim of the paper is to introduce a modified hybrid algorithm to solve a wait-and-see reformulation of transportation optimization model including linear pricing with random demand parameters and 0-1 network design variables. We model the linearly price-dependent stochastic demand and the uncertain demand parameters are introduced and modeled by random variables. Our formulated scenario-based model can be repeatedly solved as a finite set of mixed integer linear programs 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 are illustrated by network and function graphs, which are also discussed and concluded in the paper.
