“…The Complex Systems team of the Airports of the Future Research group (ARC Linkage Grant LP0990135) was approached initially by the Australian Customs and Border Protection Service (ACBPS) to develop a model of overall system performance regarding international inbound passenger facilitation time. Through workshops and interviews, a model developed that was able to simulate passenger facilitation performance [33]. The complex output of this model required further interpretation to be useful to …”

“…They are widely used as a tool for automated learning in Artificial Intelligence [27]- [29], as well as for integrating disparate data and capturing expert opinion on decision processes [30], risk factors [31], [32], operations management [33] and rare events [34]. BN models output results in terms of likelihood of existing in a given state (or on a point of a continuous distribution in the case of continuous BNs [35]).…”

Bayesian Networks are complex systems models that present rich output that can be difficult to communicate to users. In this paper a novel information visualization tool is evaluated for performance on accuracy, efficiency and user comprehension criteria. The visualization is tested across a range of user tasks, including identifying important information, inferring relationships between factors and comparing model outputs. While the interpretation of model output is less accurate for the visualization tool in question, this is balanced by significant gains in efficiency and user comprehension. It is suggested that the visualization is appropriate in contexts such as operational management where users refer to the tool often for support in making uncertain decisions, and can best be defined as a casual visualization to complement existing decision making activities on a daily basis.

“…Thus, for SCO, these are security control objects and procedures influencing the level of security and capacity. In this way, the study [18] became the basis for developing a model of security control system readiness. The division of the system was implemented in the following models: the Business Process Modelling Notation (BPMN) model, Hybrid Queue-Based Bayesian Network (HQBN) model and the Agent-Based Model (ABM).…”

“…The authors claim it is necessary to assign weights to individual variables. Instead of the classical approach (the social, technical and natural environment), the authors in [18] propose a division of the socio-technical system into three groups of objects: static objects (object relationships, object definition), dynamic objects (events, activities, processes) and behaviour objects (performance, matrices). Thus, for SCO, these are security control objects and procedures influencing the level of security and capacity.…”

Model of reliability of security control operation at an airport

Preliminary communicationThe 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.

Svi putnici i njihova prtljaga prolaze sigurnosnu provjeru. Sustav te provjere je vrlo specifičan sustav. S jedne strane sigurnosna se provjera mora obaviti učinkovito kako bi se odstranili zabranjeni predmeti tijekom pregleda, a s druge strane treba biti učinkovita tako da zbog putnika koji je prijavio pregled prtljage avion ne treba kasniti. Gore spomenuti kriteriji su proturječni. Zbog toga se u radu predlaže model pouzdanosti sigurnosne provjere s više kriterija koji uzima u obzir pravovremenost i učinkovitost postupka provjere kao i pouzdanost uređaja koji se koriste za sigurnosnu provjeru. Razvijeni je model primijenjen u procjeni funkcioniranja sigurnosnih pultova na aerodromu u Wrocławu. Model omogućuje procjenu utjecaja kvalifikacija djelatnika sigurnosne provjere (njihovu učinkovitost) na pouzdanost provjere.
