Design of Airline Hub-and-Spoke Network Based on Airport Capacity Envelope
From the perspective of airlines,building a hub-and-spoke network has become a strategic need for the development of airlines.When constructing the optimization model of hub-and-spoke network,the traditional ap-proach is to regard the airport capacity as a constant value and consider the optimization problem of constant capacity(model B).In this paper,the airport capacity was regarded as the function of arrival and departure flights,the airport capacity envelope was obtained,and the airline hub-and-spoke network design model(model A)based on the airport capacity envelope was constructed.Then we took the operation data of China United Airlines in 2017 and 2019 as an example,and compiled MATLAB program based on particle swarm optimization algorithm to solve model A and model B.The results show that the network optimization model based on airport capacity envelope can optimize a better hub-and-spoke network and further reduce the total network cost of airlines.
