Airlines
Published in Milan Janić, System Analysis and Modelling in Air Transport, 2021
A route of an airline network consists of a pair of airports and a link connecting them. The link will exist if there is at least one non-stop flight scheduled between the airports in a given period (a day, week, and month). Two concepts of air route capacity have been frequently considered: the route supply capacity and the route productive capacity, both determined for some period (τ). The route supply capacity can be estimated as follows (Janić, 2000; Vuchic, 2007): RSC(τ)=fmax(τ)⋅swhere fmax (τ) is the maximum flight frequency, e.g., the maximum number of flights that can be carried out on a given route during time (τ) (dep/h or day); ands is the average seat capacity of an aircraft carrying out the flights fmax(τ) (seats; tons of payload).

In the analysis of a weighted network, previous literature assessed the associated capacity (Cats, Koppenol, and Warnier 2017), the Origin-Destination flows (Hamedmoghadam et al. 2021; Xu, Chopra, and Lee 2021), or both (Goldbeck, Angeloudis, and Ochieng 2019). This paper adopted the capacity data for the robustness analysis because the O-D flow data is currently not available. We estimated the route capacity (passengers per day) based on the vehicle capacity and the timetable. Between sequential stops, the link capacity was computed from all parallel links that belonged to different bus routes. The maximum capacity of a bus link is where is the set of IDs of the contributed routes.
