Efficiency Analysis Of A Congested Brazilian Airport Applying Slots Optimization Control: Congonhas Airport Case

The current slot allocation mechanism in Brazil, based on the International Air Transport Association (IATA) rules, and its supplementary local regulation The National Civil Aviation Agency (ANAC), displays a few issues and limitations (e.g. slot misuse, allocation inefficiencies). Such issues are particularly present in the case of busy airports that works near their maximum capacity for major parts of the day. This inefficiency problem is generated because of the complexity of slot allocation added to the limited decision support available for the Brazilian system. This study focuses on the implementation of an optimal slot model, based on IATA regulations with local adaptations from ANAC at Congonhas Airport (CGH/SBSP). Final results include the reallocated slots examined within airport capacity limits and declared capacity for flights GOL 1389 and GOL 1666. This optimal solution represents an improvement in the slot allocation efficiency of 35,22% and 67,83% for flights GOL 1389 for GOL 1666 respectively. The main limitation is that the model focuses only on the availability of slots and their optimization. No consideration is given to the airport capabilities such as gate availability, baggage handling capacity and aircraft size. This leads to a less systemic analysis of the whole system.
