摘要：	The perception of maritime security in the post 9/11 era has been changed to focus on prevention and managing risks of terrorist attacks on the nation's supply chains, specifically the ports. Ports remain a vulnerable terrorist target because of high volumes passing through large concentrated ports. Government and industry participants have played a major role in tightening maritime security by implementing legislation, programs, and technologies that focus on developing more secure and transparent supply chains. This research effort was to evaluate the effects that various port security measures have on an electronic firm's supply chain for the movement televisions through the six major west coast ports. A constrained transportation optimization model was developed to represent the firm's distribution system. Using the firm's distribution network, the study expanded the model to represent all the television imports into the west coast and further expanded it to represent all of the west coast import volume. Three scenarios were evaluated for the firm, industry, and west coast volumes. The first scenario estimated the effect of increasing the rate charged for services at the port by five, ten, and fifteen percent. Scenarios two and three investigated the impacts of shutting down operations at the Ports of Seattle and Long Beach. Results in all scenarios indicated that the impacts at the ports caused an increase in per-unit costs, while the total transportation cost decreased because of loss of quantity demanded. The results for the firm and industry level volumes were similar, but the west coast model produced larger impacts. The port rate scenarios caused the most changes among distribution centers and retail store locations in response to increased costs. The port shutdown scenarios created the largest impacts because of the shifting of volumes that occurred between the ports, thus creating a chain reaction to optimize cost for shipments to distribution centers and retail store locations. Overall, the key insights of this study are the adjustments a firm makes to their distribution systems to counteract negative impacts imposed at ports, while meeting demands and maintaining supply chain efficiency.
