Proposed Model

A model was developed for network design of a shipping service for large-scale intermodal liners that captured essential practical issues, including consistency with current services, slot purchasing, inland and maritime transportation, multiple-type containers, and origin-to-destination transit time. The model used a liner shipping hub-and-spoke network to facilitate laden container routing from one port to another. Laden container routing in the inland transportation network was combined with the maritime network by defining a set of candidate export and import ports. Empty container flow is described on the basis of path flow and leg flow in the inland and maritime networks, respectively. The problem of network design for shipping service of an intermodal liner was formulated as a mixed-integer linear programming model. The proposed model was used to design the shipping services for a global liner shipping company.

Node Capacity

To evaluate the transportation time reliability of the maritime transportation network for China’s crude oil imports under node capacity variations resulting from extreme events, a framework incorporating bi-level programming and a Monte Carlo simulation is proposed in this paper. Under this framework, the imported crude oil volume from each source country is considered to be a decision variable, and may change in correspondence to node capacity variations. The evaluation results illustrate that when strait or canal nodes were subject to capacity variations, the network transportation time reliability was relatively low. Conversely, the transportation time reliability was relatively high when port nodes were under capacity variations. In addition, the Taiwan Strait, the Strait of Hormuz, and the Strait of Malacca were identified as vulnerable nodes according to the transportation time reliability results. These results can assist government decision-makers and tanker company strategic planners to better plan crude oil import and transportation strategies.

The Impact

The terrorist acts that destroyed the World Trade Center and part of the Pentagon have, of course, changed much of the world in many ways since September 2001. Among those effects has been a pronounced and noticeable shift in airport and aircraft security. Much less noticeable to most Americans has been the impact of added security and changed priorities on maritime transportation systems. But maritime security actually has a far greater impact on commerce than does air security because most cargo moves worldwide via commercial ocean-going vessels. Security requirements and wartime priorities are compelling the worlds governments to more closely monitor and inspect all vessels and cargo entering their nations ports. The US Coast Guards inspections are forcing tremendous delays upon entering vessels. The consequences of losing millions of dollars daily both for shipping companies and cargo interests create severe economic and logistical problems that impact all transportation modes. The new US embargo on 24 small countries may force them into bankruptcy unless they comply with US requests to end terrorism. These countries depend on exports and imports for a large portion of their GDP, which will be dramatically reduced unless they join the war against terrorism. This paper examines five impacts on the US and world shipping industry caused by the war on terrorism--those on: 1) vessel and port security; 2) transportation- and trade-related communications; 3) trade levels; 4) marine insurance; and 5) maritime and related freight rates. Then the authors draw some conclusions regarding possibilities of reflagging of ships and effects on the status of the US merchant marine industry.

Regional Problems

In December 1993 Secretary of Transportation Federico Peña called for the creation of a National Transportation System (NTS). The goal of the NTS is to support national transportation planning and policy that maximize the efficiency and effectiveness of the nation's transportation network, in accordance with the mission of the Intermodal Surface Transportation Efficiency Act of 1991 (ISTEA). It is proposed that the U.S. Department of Transportation (DOT) pursue this goal by designing an NTS that can monitor the performance of the nation's transportation network; detect national and regional problems with the transportation system; facilitate the setting of performance goals and measure progress over time; and aid states and metropolitan areas in performance-based planning. To do this, the NTS must evaluate the transportation network's performance in terms of moving passengers and goods and of achieving the goals of the system's users. Therefore, the NTS must have as its basis a set of performance measures that apply to different modes and that reflect the varied goals of ISTEA, in the areas of system output as well as the environmental, social, and economic outcomes of system usage. Such performance measures are proposed, as is a general decision-making framework for using them. The ISTEA legislation, the NTS initiative, and potential data sources for supporting these performance measures are also examined.
