Previous studies on airport security have investigated alternative policies based on costbenefit analysis, but they have faced significant problems in the lack of considering social aspects of security policies as well as the concrete measurability of model parameters. Moreover most of the policies and strategies in aviation security have been implemented as a reactive result of terrorist activities rather than motivated by a proper assessment.
