During a few months of the year seasonal airports face the challenging task of maintaining service quality while dealing with heavy traffic, often being pushed to operate on the limit of their available capacity. Under such circumstances, efficient allocation and timely reallocation of physical and human resources is what keeps the service quality of airports at an acceptable level. The paper describes a tool to support allocation of the physical resources, developed for particular seasonal airport falling in the range 1–5 million annual passengers. The tool is designed to work with the traffic schedule – to check it against existing constraints imposed by area, and to assign the appropriate alert if any of the constraints are violated. Thus, the tool provides airport planners with a clear overview of the traffic situation. Its main function is to allow airport planners to check the effects of different actions to resolve particular constraints violations on the overall situation, before making the final decision. Due to non-disclosure agreement, the tool and its features are presented in the paper on somewhat modified example.
