Optimising airport slot allocation considering network-wide interactions

The rapid air-transport growth coupled with political, physical and institutional constraints in building new airport capacity has resulted to acute airport congestion.

Traditionally, capacity at congested airports is expressed in slots. Currently used slot allocation procedures result to sub-optimal airport capacity utilisation with significant impacts on airport revenues, airline operating costs, and passenger level of service.

The objective of this project is to develop and solve models aiming to optimise slot allocation for a: i) single airport, and ii) a network of airports. The resulting slot allocation problems will be formulated as integer optimisation models which will consider simultaneously airline and airport operators’ objectives, and a set of operational and regulatory constraints. The contribution of the proposed project stems from the: i) formulation of alternative optimisation models using different airline and airport utility functions, ii) development of a methodology for determining, as opposed to setting, the airport declared capacity, iii) consideration of the inherent interaction of slots at airport-network level, iv) development of efficient algorithms for solving the resulting large scale slot allocation models.
