Homeland security airport security model
This model provides a framework for helping to understand and analyze the airport security problem. By modeling the security process, and identifying the weak points, we were able to make recommendations for possible Federal initiatives through legislative or management action to close the identified security loopholes. Passenger flow through the ticket counter, security station, and gate, which potentially includes terrorists, is modeled and quantified. A probability model estimates the probability of a terrorist escaping detection at the various stations. This probability is a function of the reliability of a proposed security database and the reliability of security equipment. The influence of these reliabilities on the probability of non detection is studied. In addition, a commonly overlooked security problem -- overloading security personnel with passenger traffic to the extent that they are distracted from thoroughly checking passengers - - is modeled and analyzed. Model quantitative results are used to delineate the implications for changes in security policy at the nation's airports.
