Network analysis of container barge transport in the port of Antwerp by means of simulation 总被引:2,自引:0,他引:2
Inland navigation plays an important role in the hinterland access of the port of Antwerp. In this paper alternative bundling strategies for container barge transport in the port of Antwerp are analyzed. Four alternative hub scenarios are simulated and compared with the current situation with respect to the operational characteristics of the network. Discrete event simulation is used to analyze the impact on waiting times and capacity utilization at potential hubs and at sea terminals. The hub scenarios under investigation are the organization of an intermodal barge hub on the right river bank, an intermodal hub on the left river bank, a first multihub scenario with a local collection/distribution network and a potentially improved multihub scenario taking into account the specific structure of the port of Antwerp. The second multihub scenario offers most opportunities for reducing the turnaround time of all inland terminals. All hub scenarios lead to important efficiency improvements in the handling of barges at sea terminals. 相似文献

This paper analyzes the intermodal transportation network of containerized imports to the United States. An optimization model is developed that integrates international and North America inland transport networks. The results indicate optimal ship size, route, port, and interior shipping corridor and are highly reflective of observed shipments. Sensitivity analyzes were performed to evaluate impacts of congestion on capacity constraints as well as the prospective impacts of the alternative routes that are emerging. Results indicate that Prince Rupert is highly competitive for shipments to some markets, but the expansion of the Panama Canal would have lesser impacts on container flows. 相似文献

We propose a bi-objective optimization framework for routing rail-truck intermodal shipments with hazardous materials, when shippers and receivers have access to alternate intermodal terminals. A tabu-search based solution methodology is developed, which together with the optimization framework is applied to realistic size problem instances to gain managerial insights. Our analysis indicates that drayage accounts for a significant portion of transport risk and that it can be reduced by scheduling direct and faster trains; and, that the mix of intermodal trains depends on the interest of the decision-makers, where the resulting traffic can facilitate planning emergency response systems. 相似文献
