Functional Resonance of the Airport Passengers Security Check

The aim of this work is evaluation of the process of airport passenger and cabin luggage security check, using methods originally dedicated to safety engineering. The evaluation is based on the Functional Resonance Analysis Method (FRAM) and the applied computation of the model follows existing research on FRAM. Variability for each security check function in terms of time and precision is defined, considering also the external conditions affecting the system. Next, an application is developed, which represents the interface between the FRAM-based calculations and the user. The main goal of the application is evaluation of security check according to the provided measurement inputs and provision of practical representation of the results to the industry experts. The results indicate that FRAM can be used for the purpose of modeling security systems and that the modeling results can help industry experts to identify their weak points, together with suggestions how they could be improved.
