Evolutionary Fleet Development Considering Airport Capacity Limitations and their Mitigation

Influence of Airport Capacity Limitation Mitigation on Air Traffic Networks and Fuel Consumption

“…The system view of airport congestion effects requires an integrated approach to modeling future fleet development and airport capacity constraints ("integrated model" in the following). Such an approach was described by Michelmann et al [8], using an evolutionary fleet development model after Randt [9] to derive scenario-based estimates of future global fleet development. Important simplifications in this modeling approach include the clustering of routes into route groups between and within six air transport network (ATN) regions (as of OAG 2016 [10]) and of aircraft into aircraft clusters.…”

“…The former are represented by frequency-based average routes per aircraft cluster, the latter by a representative aircraft type. Current technology aircraft clusters can be complemented by new and future technology clusters, e.g., to investigate the fleet uptake of novel aircraft designs (see [8] for more information on the clusters used). Different airlines are not modeled, as the focus is on technology assessment and global network aspects.…”

“…APC5 and 6 are small airports with usually limited regional significance. [8] By comparing demand and supply, we can identify surplus traffic at congested airports as demand which cannot be accommodated by the airport. As airlines usually still want to cover that additional demand, strategies for mitigating capacity constraints are implemented [8], as shown in the subsequent section.…”

As airlines usually still want to cover that additional demand, strategies for mitigating capacity constraints are implemented [8], as shown in the subsequent section. Surplus traffic which cannot be accommodated despite using mitigation strategies is called remaining surplus.…”

“…A model integrating the scenario-based simulation of global air transport fleet development with airport congestion and strategies for its mitigation (in the following "mitigation strategies") was introduced in preliminary work [8]. The implemented mitigation strategies comprise shifting traffic to uncongested airports and using aircraft with higher passenger capacity.…”
