Generally, finding out the average security wait time is not as easy as it appears. This is because people (or vehicles) do not arrive at the queue on a precise schedule, not to mention the need for security check which makes the service process more involved. The objective of this proposal is to construct a queueing model to assist the Transportation Security Office understand how to design and manage the security wait environment with customers' satisfaction, e.g. the normal wait time is no more than 30 minutes. To accommodate the seurity conditions in practice, such as check in various security stages, we use a queueing model with service time of semi-Coxian distributions. The semi-Coxian distribution in fact complicates the computation but reflects relatively better estimation than a traditional model. Thus, it is useful both to maintain the security level and to release the tense in the security check points in airports, or international borders. The basic computable model will be built in the first year and further investigation for implementation issues and verification will be conducted in the second year.
