Abstract
We study a planning problem for freight carriers that aims to profitably match supply and demand under uncertain shipment volumes. On the supply side, decisions on hub locations and vehicle dispatches are made over a planning horizon. On the demand side, the carrier can expand service by selectively accepting additional long-term and transactional customers. The problem is formulated as a two-stage stochastic program and solved using an enhanced Benders Decomposition. Computational results demonstrate clear improvements over benchmark methods and the benefits of solving the integrated model.
