摘要

We present a computational analysis of the planning horizon effects on emptycontainer management for multimodal transportation networks. A distinctive aspect of our analysis is that we consider three different modes explicitly, namely truck, rail and river barge. The barge mode makes the network structure and underlying operational problem interesting, since it is the slowest and cheapest of the three modes. To analyze how the planning horizon affects the empty container flows in such a multimodal network, we develop an integer programming model. We discuss the sensitivities of initial inventory at each container pool, number of container pools in the system, and transport mode usage to the length of planning horizon. We conduct controlled experiments using the actual Mississippi River basin network. Our results show that the application of long planning horizon (used on a rolling basis) can give a better empty container distribution for the earlier periods. The longer horizon allows better management of container outsourcing and also encourages use of cheaper but slower transportation modes, such as barge. However, the advantages of using a rolling horizon might be small for a system that has a sufficient number of container pools since such a system has small end-of-horizon effects. We finally discuss related issues that one needs to consider when determining the length of planning horizon.
