Project Objective:
The purpose of this proposal is to investigate methodologies to optimize the interchange of empty containers outside the marine ports. In particular we plan

1.To formulate the problem of empty container interchange, and provide analytical models.
2.To develop optimization techniques, that will minimize the cost of empty container interchange given demands and supplies of empties in deterministic and stochastic environments.
3.To develop realistic simulation scenarios using past, current and projected data in the Los Angeles/Long Beach port area. These scenarios will be used to evaluate the developed optimization methods.

The Los Angeles/Long Beach port complex is the intermodal gateway to Pacific Rim trade and busiest container port complex in the United States comprising of fourteen individually gated terminals. In 1999, the combined ports handled 8.2 million 20-foot equivalent units (TEUs). This figure implies that almost 4.43 million full containers were handled during 1999 in the LA/LB port complex[1]. Each container is typically handled twice, once as a loaded container, and the second time recycled as an empty. This translates into 8.86 million containers moved one way annually by road or rail within the region in 1999.

The loaded containers arriving at the port are picked up and transported by trucks to their destinations. After having been unloaded, they must be picked up as empty containers. The empties are typically moved back to the port (or in some cases to another depot - inland port). The exporters, who need empty containers that will be filled with exportable goods, will hire another trucking company to pick up the empties from the port, and transport them to their locations. After empties have been loaded at the export firm, the truckers will transport them back to the port where they will be loaded on the ship for export. A system, which facilitates the interchange of empties outside the ports, is necessary. This system will reduce the truck trips to and from container terminals, and as a consequence, will have major environmental effects. It will reduce the traffic congestion around the ports and therefore, reduce noise and emissions in addition to saving time for both truckers and port operators.

[1] Typically a container could be 20 ft or 40 ft in length, but the vast majority of containers are forty feet. It is estimated that on the average, a random container would correspond to 1.85 TEU [4].
