Abstract:
The overload and insufficient supply of air traffic lead to imbalances in airport systems,
resulting in increased operational costs, frequent flight delays, and passenger discomfort. These
factors are recurring issues in the sector and create challenges in operational processes, thus
directly affecting the efficiency and quality of services offered by airports and airlines.
Therefore, this study aims to develop an optimization heuristic based on local search to solve
the aircraft landing problem at an airport with a single runway. This approach aims to improve
operational efficiency and air traffic management. The methodology used to achieve the
research objective is classified as applied in nature, and in terms of approach, goals, and
technical procedures, it is characterized as quantitative, exploratory, and case study,
respectively. The study was carried out in six stages: data collection from a real database to
build the instances used in the heuristic approach, a literature review, an understanding of the
mathematical modeling of the aircraft landing problem, the construction of the heuristic
method, the execution of computational results, and the statistical analysis of these results. The
results showed that the proposed heuristic efficiently generates possible solutions with feasible
computational execution times. Additionally, in experiments based on three instances using real
data from Recife/Guararapes International Airport, the average total discrepancies ranged from
3875 UT to 3945 UT, with a standard deviation between 310.4 UT and 321 UT for the ten
executions that the instances underwent. In summary, the proposed approach was determined
to be a functional and practical tool for air traffic management.
