These two issues have not yet been considered simultaneously in the scientific literature. So far, the focus has been placed on process performance. However, this paper shows, by performing an empirical study and applying the proposed model, that it is important to consider these two issues simultaneously. This will allow for the sustainable development of air transport. As a case study, three system configurations for single, dual and single fast screening lanes were analyzed. For each configuration, 3 different types of X-ray devices were checked, and the results were compared. The results showed that for example calculations with 2 million passengers handled per year, the gains could be as high as 4614 kWh/year. This article therefore shows that it is important to manage the process with power consumption in mind. Keywords: airport; security control; process management; simulation modelling; power consumption 1. Introduction Power consumption costs airports as much as 15% of expenses for operating activi- ties [1]. Over 75% of the power is consumed by the terminal buildings [2]. The remainder is the maintaining of the navigation infrastructure, runway lighting, taxiways, aprons, etc. Inside the terminals, there are cooling, lighting and air ventilation facilities as well as information and technical infrastructure for passenger service. This article will focus on analyzing the operation of equipment that relates to passenger service. Power consumption is at every stage of passenger and baggage handling. The passen- ger completes the transport process at the check-in, security screening, documents control, gate. The highest power consumption is at the security checkpoint, where each security lane is equipped with electrical devices like X-ray, explosive trace detectors, metal detectors, body scanners, etc. There are also supporting devices that control the flow of baggage like belt conveyors and roller conveyors that are controlled by electric motors or manually. The primary purpose of the system is to scan the passenger and items in the passen- ger’s possession. This screening is designed to identify items that could lead to an act of unlawful interference by a passenger. The screening lane must also have an adequate level of performance [3]. The airport operator must ensure that the screening system is efficient enough to allow passengers to arrive at the gate on time. This system is usually designed to be redundant and is managed by the scheduling of security line operations. The manner in which screening is conducted and the passenger space is important on Level of Service (LoS) [4–6]. LoS is directly related to the airport’s non-aeronautical revenue. The higher the LOS the higher the revenue. According to [7], 40–60% of airport revenues are from non-aeronautical activities.
