Locating urban flying car vertiports part Ⅱ:two-stage optimization for hub-and-spoke networks
摘要
Abstract
[Background]Novel,low-altitude transportation systems based on flying cars can poten-tially alleviate ground-traffic pressure(caused by increasing,severe,urban-traffic congestion).Personalized service demands require systematic research on vertiport siting(selection and layout).[Objective]This study addressed optimal vertiport-siting requirements in urban environments.To balance multiple objectives,such as construction costs,service efficiency,and safety margins,a hub-and-spoke network architecture incorporating vertiport heterogeneity was constructed.A theoretical foundation for scientifically informed urban vertiport siting was thereby provided.[Methods]A two-stage optimization framework was proposed.Phase I:a multi-objective programming model was de-veloped to determine the optimal locations and affiliation relationships for primary and secondary vertiports,incorporating construction,coverage,and linkage costs.Phase Ⅱ:a route-planning model was formulated with to minimize total flight time,fleet size,and affiliation penalty.The optimization problem was solved using a hybrid approach that integrates simulated annealing,greedy algorithms,and local search strategies.[Data]The publicly available Chicago-Sketch network and related data were used,and the number of primary vertiports constructions and weighting ratio of different targets were considered.[Results]Our research demonstrated that the hub-and-spoke network structure sig-nificantly reduced vertiport construction costs,and the system achieved an optimal balance between performance and cost when five primary vertiports are deployed.Under the optimal configuration,the total flight time was 210.4 minutes,with an average flight time of 46.7 minutes per route,ensur-ing a 22.3％energy safety margin.关键词
