Model of reliability of security control operation at an airport

The aim of the operation of the security control system at an airport is the prevention of the introduction of forbidden objects to the restricted area of the airport or onto the plane. All passengers and their luggage undergo security control. The security control system is a very specific system. On the one hand, the security control must be performed effectively so as to eliminate forbidden objects during the inspection and, on the other hand, it should be efficient so that the passenger who has checked in his/her luggage does not cause the aircraft to be delayed by a long wait. The criteria mentioned above are in conflict. For this reason, the study proposes a multi-criteria model of reliability of the security control operation, which takes into account both the timeliness and effectiveness of the control process as well as the reliability of devices that are used to perform security control. The developed model was used to evaluate the operation of the security counters at the Wrocław airport. The model makes it possible to assess the influence of security control operators' qualifications (their effectiveness) on the reliability of the control.
