Persistent and ever-changing threat of terrorism has led to the evolution of security systems in the air transportation industry. Passenger and checked-baggage screening prior to boarding an aircraft has become a priority for the airport security system. We propose a two-stage screening system by integrating the passenger prescreening and a multi-level checked-baggage screening. Based on the concept of the weighted k-out-of-n system, we introduce an integrated weighted alarm security screening system for a multi-level baggage screening system, where the system alarms when the total weight of its working levels is greater than a predefined system alarm threshold. To improve the security and efficiency of aviation systems, two optimization models are formulated to enhance the detection of possible threats in the passenger and baggage screening with consideration of the system life cycle cost. The optimal solutions of the threshold values are obtained for screening technologies and passenger classes to achieve the maximum security and efficiency. Numerical analysis is implemented to demonstrate the effectiveness of the proposed two-stage screening system.

The use of non-metallic pipes and composite components that are low-cost, durable, light-weight, and resilient to corrosion is growing rapidly in various industrial sectors such as oil and gas industries in the form of non-metallic composite pipes. While these components are still prone to damages, traditional non-destructive testing (NDT) techniques such as eddy current technique and magnetic flux leakage technique cannot be utilized for inspection of these components. Microwave imaging can fill this gap as a favorable technique to perform inspection of non-metallic pipes. Holographic microwave imaging techniques are fast and robust and have been successfully employed in applications such as airport security screening and underground imaging. Here, we extend the use of holographic microwave imaging to inspection of multiple concentric pipes. To increase the speed of data acquisition, we utilize antenna arrays along the azimuthal direction in a cylindrical setup. A parametric study and demonstration of the performance of the proposed imaging system will be provided.

Successful Execution

Visual search—the ability to locate visual targets among distractors—is a fundamental part of professional performance for many careers, including radiology, airport security screening, cytology, lifeguarding, and more. Successful execution of visual search in these settings is critically important because the consequences of a missed target can be horrific. Unfortunately, many of these professions place high demands on the people performing the searches, and either the task or the environment (or both) could lead to significant errors. One known source of error that exists across many fields is “multiple-target visual search” errors—a target is less likely to be detected if another target was already found in the same search than if the target was the only one present. These errors have proven to be stubborn and not easily eliminated. This article offers a brief overview of the existing research on multiple-target visual search errors and discusses possible policy implications of the errors for airport security screening. The policy suggestions are based on empirical research, with the hope of providing food for thought on using scientific data and theory to improve performance. Specifically, three policy suggestions are raised: shift screening to a remote location away from the checkpoint, reduce the number of prohibited items to lessen the searchers’ cognitive burden, and emphasize search consistency in the training process. Note that the focus here is on airport security screening, as this is a domain most readers can relate to, but the suggestions can equally apply to many search environments.
