Treść
Every passenger who makes an air journey is first subjected to security screening. As part of this procedure, passengers must be screened by a walk-through metal detector (WTMD). On the one hand, such devices should effectively detect prohibited metal items, while on the other hand, they should ensure adequate throughput at a security screening checkpoint. One must adopt a certain method of evaluating both these factors in order to be able to select an appropriate walk-through metal detector and its parameters. While it is easy to establish passenger throughput, it is much more difficult to determine a detector’s effectiveness, which is a subjective concept. Therefore, the aim of this paper was to develop a quantitative method for evaluating the effectiveness of a WTMD. Since this evaluation is subjective and, at the same time, there is no complete, precise input information, a fuzzy inference method was used; input values are expressed as linguistic variables. Many field measurements had to be carried out, mainly of walk-through metal detectors’ sensitivity, and a survey had to be conducted among experts in order to correctly determine these values. The model for evaluating a WTMD that has been developed, together with the computer tool FUGAS (FUzzy Gate Assessment System) that has been created, make it possible to evaluate the effectiveness of the existing types of WTMDs. This paper presents an example of such an evaluation which was carried out at the Katowice-Pyrzowice airport. Also, a universal walk-through metal detector sensitivity scale was developed, and the relationship between a WTMD’s effec-tiveness and the sensitivity it had been set at was analyzed. The experiments that are presented in this paper show that fuzzy inference systems can be effectively used to assist an airport manager in selecting the equipment and its parameters for a security screening checkpoint at an airport.
