Research On Vertiport Location For On-demand Delivery By UAV In Urban Aera

With the rapid development of e-commerce and the distribution boom,there have been problems with mismatches in riders,facilities and the huge demand for city distribution.Since the outbreak of new crown disease in late 2019,people have paid more attention to their own safety and health,and a kind of real-time delivery mode with unmanned aerial vehicle(UAV)automatic airport as the zero contact point has emerged.The application of UAVs in the express delivery industry has an inestimable future development space,both in terms of the future demand for UAVs and in terms of the distribution cost of UAVs compared to manpower distribution,drones are the future of express delivery.In order to solve the problem of resource mismatch in the current distribution process,the small unmanned aerial vehicle(UAV automatic airport-‘zero contact’)is adopted to carry out the real-time and effective distribution of parcels,in order to realize the real landing of UAV fully automatic airport distribution mode,it is necessary to study the site selection of UAV fully automatic airport,a multi-objective mixed integer programming model with minimum cost as objective functions.The characteristic of multi-UAV and multi-demand points makes the classical NP-hard problem and the local optimal problem in the research of UAV automatic airport location.Therefore,this paper proposes a method to reduce the dimensions of the problem by zoning the location area,so as to achieve the global optimization of the UAV automatic airport location results.Taking the real-time distribution commercial data of Heping District as an example,the results show that the zoning optimization method can make the distribution of demand points among districts more balanced and achieve the goal of global optimization.Compared with the distance by car,it is found that the coverage area of autonomous airports is related to the balanced distribution of the number of locations and demands.This zoning optimization model reduces the difficulty of establishing fully automated airports in urban areas in the future,and ensures the balance and practicality of airport use.
