An analysis of the cabin baggage security screening process incorporating automation elements

The existing regulations impose the obligation to perform random cabin baggage security screening for the presence of traces of explosives (explosive trace detection, ETD) at airports. As a result, a problem arises in relation to the proper organization of security screening checkpoints and the provision of telematic devices used to facilitate the process. The study considered three options a) a dedicated ETD checkpoint, b) ETD screening in all security checkpoints, c) equipping all checkpoints with an explosive detection system (EDS). The purpose of the paper is to propose a mathematical model and conduct a practical evaluation of options concerning security checkpoint modernization in terms of the following criteria: capacity, cost, and efficiency of detecting prohibited substances. An independent evaluation was conducted on the basis of the criteria, considering the analysis of the actual inflow of baggage in individual security checkpoints and the annual costs of equipment and staff, while the efficiency of screening was subjectively evaluated by experts. The proposed mathematical model and the established calculation tool were used to evaluate the options of security checkpoint organization at Katowice Airport. As a result of the conducted analysis, option c) was recommended. This solution showed the best results in terms of capacity and efficiency and generated medium costs
