Yang Liuzhuang express drone application and development study

This paper presents a feasibility study on the application of delivery drones in Yang Liu Zhuang. In order to make the cost calculation convincing, the article realistically simulates the delivery scenario of Yang Liu Zhuang during the epidemic, and then analyzes its transportation cost in depth, and finally concludes that using drones to partially replace traditional delivery in Yang Liu Zhuang can save costs and improve logistics efficiency. However, at present, the delivery by express drones is mainly limited by their own load weight, and they cannot deliver medium and large goods.
