| Abstract | Currently, due to the continuing increases in demand, the U.S. freight transportation system is running at capacity and disruptions are commonplace. However, by improving the operational characteristics of the major resources in the network, the underutilization of capacities can be reduced and, therefore, the impact of disruptions can be mitigated. The purpose of this research is to study methods of modeling and evaluating the freight operations and distributions and to develop mitigation strategies for reducing their impact at terminal, port, and regional levels with special emphasis given to the ports of the U.S. west coast region.; The objective at the terminal level is to minimize the effect of disruption on the terminal throughput. In order to effectively utilize the capacity of terminal, we focus on the scheduling problem of calling vessels on a berth. It is the most essential planning since terminal operators are required to coordinate the deployment of various resources so that freight are moved as smoothly and as quickly as possible. We developed mathematical models and optimization methods for the berth allocation problem (BAP). The objective at the port level is to route ships to different terminals within the port so that the overall port throughput is affected less by disruption. We focus on the scheduling problem of calling vessels on multiple berths which is referred to as the multiple berth allocation problem (mBAP). We developed mathematical models and optimization methods for the mBAP. The objective at the regional level is to develop a mitigation strategy so that the regional throughput in moving goods is less affected by disruptions. The regional service network is defined at a high level of aggregation, which includes the major ports and aggregated zones representing broad geographical destinations and intermediary locations. The regional service network under disruption is modeled as the minimum cost flow problem with binary (or, integer) constraints. Furthermore, toward future integrated evaluation works, we address the problem of improving the capacity utilization of a transportation link (a freeway stretch) using an integrated freeway traffic control system comprised of ramp metering and variable speed limit strategies. |
