报告简介

With increasing container-shipping traffic, congestion at transshipment hub ports happens from time to time incurring longer-than-expected waiting time for vessels and loss of transshipment connections. This situation is even worse for feeder companies, due to their relatively lower berthing priority. It is essential to design the feeder vessel routes and schedules in response to hub port congestion while ensuring efficient transshipment connection. In this paper, we study, for a feeder liner company, the vessel routing and transshipment coordination problem with limited choices of berthing time slots. We propose a set covering model with the objective of minimizing total operational cost and transshipment connection cost. A branch-&-price exact algorithm is developed, which can solve instances with up to 30 ports to optimality within one hour. Computational results based on a real-world shipping network demonstrate that, by integrating the hub port visiting time decision with feeder vessel routing, transshipment coordination can be significantly enhanced even under hub port congestion situations.
