In recent years,with the rapid development of online shopping and e-commerce,customers have become more and more demanding on the personalization and timeliness of orders.The delivery of pick-up tasks by UAV has gradually become an emerging research field.Several express delivery companies have carried out real testing of UAV delivery and pickup.In order to study the joint scheduling problem of UAV delivery and pick-up in e-commerce small parts express delivery,under the premise that the drone is flying at a constant speed,according to the characteristics of drone energy consumption at this time,which is only related to speed,there will be There are three modes of energy consumption when UAV responds to wind resistance: low speed and low energy consumption,medium speed and medium energy consumption,and high speed and high energy consumption.By constructing a UAV delivery and pickup model,designing a genetic algorithm,and studying three UAV energy consumption modes to complete the same batch of delivery and pickup task scheduling under the background of an example,the effectiveness of the model and algorithm was verified by an example.The specific research work is as follows:First of all,this article describes the concept,current situation and existing problems of e-commerce express logistics distribution,and introduces the related concepts,advantages and disadvantages of drone distribution.By analyzing the application scheduling model of UAV,it is confirmed that the research scenario of this paper is the distribution priority and backhaul mode.The force and energy consumption of the drone are analyzed,and the formula deduces that the energy consumption of the drone at a constant speed and horizontal flight is proportional to the cube of its flight speed,and the life time of the drone is equal to the cube of the flight speed.Inversely proportional.According to this characteristic,the energy consumption modes of UAV to deal with wind resistance are divided into three types: low speed low energy consumption,medium speed medium energy consumption and high speed high energy consumption.Secondly,this paper analyzes the constraints of the joint scheduling plan for UAV delivery and pickup under the distribution priority and return cargo mode,and establishes e-commerce express UAV distribution based on the constraints of outlet operating time,cruising range,carrying capacity and other constraints Based on the mathematical model of joint scheduling with pickup,a solution algorithm is designed,and detailed solution steps and algorithm flow chart are given.Finally,the algorithm is implemented through MATLAB programming to solve the distribution and pickup problems in the three modes of low speed and low energy consumption,medium speed and medium energy consumption,and high speed and high energy consumption of the UAV.The distribution and pickup requirements of large-scale distribution centers to express outlets are used as background.The proposed algorithm and designed program are used to verify,which proves that the model and algorithm proposed in this paper are effective in solving the joint scheduling scheme of e-commerce express UAV distribution and pickup.The rationality and practicality of the problem.
