Abstract
Cargo shipments are a growing part of the transport carried out by many air carriers. One of the critical elements in this area of activity is shipment security inspection, which is a mandatory part of the transportation process. This article aimed to study the inspection system's capacity under disruption conditions and determine its dependence on possible technical and organizational improvements. For this purpose, simulation modeling was applied using a microscale model of the cargo security inspection process realized in a colored, timed, stochastic Petri net. Bayesian networks representing the actual process were used to validate the model. As a result of the research, experiments showed that for Katowice Airport in Pyrzowice, more advanced technical solutions can increase capacity by up to 50%. On the other hand, introducing modifications to the procedure, involving at least two checks using specialized assistive devices, can reduce it by up to 40%. Relatively small changes in capacity are expected with changes in the training and experience of screening operators. Based on these results, it can be recommended that airport managers consider using technical solutions with the parameters analyzed in the article. In addition, it is necessary to maintain the level of training at least at the current level. At the same time, any changes in control procedures should be made prudently, only when necessary, due to the need to strengthen the effectiveness of controls during periods of increased terrorist threat.
