OVERVIEW OF AVIATION AIRPORT INFRASTRUCTURE IN THE SYSTEM OF ENSURING SECURITY PROCEDURES AT THE AIRPORT

The study examines the «SECURITY–QUALITY» model in the context of airport operational efficiency. The assessment of airport performance is based both on calculations using simple linear indicators and on the application of more sophisticated models with specific parameters and clearly defined constraints. As a result of the analysis and research, a mathematical model of «SECURITY–QUALITY» has been developed. This model reflects the full dynamics of passenger flows through the lens of all technological procedures of the airport and enables the calculation of the dynamic allocation of available resources for performing all prescribed inspection procedures, both under normal operational conditions and in emergency situations. Scientific approaches to evaluating airport efficiency include both calculations based on simple linear indicators and the use of complex models with clearly established operational constraints. The study further analyzes the impact of security measures on the time intervals required for passengers to complete necessary airport procedures, which directly depend on passenger behavior and the throughput capacity of the airport. Airport infrastructure is a fundamental component of the aviation sector, providing essential facilities and services required to ensure efficient and seamless operations as well as satisfactory quality of air passenger transportation. Supporting aviation operations necessitates comprehensive planning, design, construction, and maintenance of a wide range of physical assets, complemented by the integration of advanced technologies and systems. Within this framework, security considerations remain a priority for all technological elements and operational resources within the airport environment. Analysis of the «SECURITY–QUALITY» model demonstrates that increasing the time allocated to passenger security procedures may lead to several subjectively perceived negative consequences for travelers. Accordingly, the implementation of additional security measures - which generally require additional time and apply to all flights - results in resource deficits and increased delays in subsequent flight operations.
