Sequential Passenger and Baggage Screening Strategies for Enhancing Aviation Security

摘要

Emerging image-based technologies are critical components of airport security for screening checked baggage. Since these new technologies differ widely in cost and accuracy, a comprehensive mathematical framework should be developed for selecting technology or combination of technologies for efficient 100% baggage screening. In this paper, passenger information is incorporated in a two-level baggage screening system to determine the screening strategy for different subsets of passengers. By deploying a passenger prescreening system, this paper considers selectively applying baggage screening procedures for 100% screening. It also investigates the setting of threshold values for these screening technologies and the determination of the optimal combination of technologies. Probability and optimization techniques are used to quantify and evaluate the risk and cost-effectiveness of various deployment configurations, which is captured by using a system life-cycle cost model that incorporates the deployment cost, operating cost, and costs associated with system decisions. Numerical analysis for all possible system arrangements is demonstrated.
