Abstract

Since September 11, 2001, the United States has invested a significant amount of resources into improving aviation security operations, with the Transportation Security Administration (TSA) assuming the responsibilities for security policy-making at commercial airports. This article reviews the literature that supports policies for risk-based passenger screening procedures and chronicles the analytical analysis leading up to the launch (in October 2011) of the TSA Precheck program, as a first step toward implementing a risk-based security strategy for passenger and baggage screening. Multi-level passenger prescreening is the basis of the mathematical framework behind TSA Precheck; the framework provides a prescriptive control of security operations in settings with limited resources. TSA Precheck assigns each passenger to a risk group, based on the initial perceived risk level (assessed in the prescreening stage), and then calibrates the security measures to mitigate the risk associated with each group. With passengers arriving in real-time and the order of their arrivals uncertain, the resource utilization problem is solved by dynamic programming. A numerical comparison between a risk-based and an equal-risk (i.e., non-risk-based) security model is presented to quantify the benefits of risk-based security.

审查基于风险的安全性及其对TSA PreCheck的影响

摘要

自2001年9月11日以来,美国已投入大量资源来改善航空安全运营,由运输安全局(TSA)负责商业机场的安全决策。本文回顾了支持基于风险的旅客筛查程序政策的文献,并记述了TSA Precheck计划启动(2011年10月)之前的分析分析,这是朝着对旅客实施基于风险的安全策略的第一步和行李检查。多级旅客预检是TSA Precheck背后的数学框架的基础;该框架在资源有限的情况下提供了对安全操作的规范性控制。TSA Precheck将每位乘客分配到一个风险组,根据最初的感知风险水平(在预筛查阶段进行评估),然后对安全措施进行校准,以减轻与每个组相关的风险。在旅客实时到达且到达顺序不确定的情况下,通过动态规划解决了资源利用问题。提出了基于风险的和相等风险(即非基于风险)的安全模型之间的数值比较,以量化基于风险的安全性的收益。
