Design And Implementation Of UAV Terminal Distribution Simulation

In recent years,with the rapid increase of express delivery volume and expenses of labor,the contradictions in the terminal distribution chain are increasing day by day,and the problem of "last mile" has become a sore point in the logistics industry.At the same time,the booming development of the UAV industry provides a new way to solve the problem.Many logistics enterprises try to use UAVs to participate in the terminal distribution process,in order to reduce the labor cost and distribution pressure.The research of UAVs participating in terminal distribution mostly focuses on the joint distribution mode and joint distribution path algorithm,while the overall process of UAV terminal joint distribution scheme is less concerned.In this paper,a simulation system for the whole process of UAV terminal joint distribution in the industry has been designed and developed to provide a task data-driven distribution solution.This paper summarizes the theoretical research results of this problem at home and abroad;Three kinds of UAV joint distribution modes and the existing simulation theory and technology are summarized;Before the simulation modeling,we completed the work of workflow analysis,task planning,system model modeling,simulation system requirements and feasibility analysis,verification experiment design and so on;A UAV terminal distribution simulation system based on multi-agent simulation technology is developed;The practicability and reliability of the system are further verified by an example.The UAV terminal distribution simulation system is implemented based on anylogic software platform.Built in joint distribution mode selection,task data fast import,parameter and algorithm custom input,operation process visualization,performance index data statistics and other functions,and completed the function test.Finally,the practicability and performance of the simulation system are further verified by an example.The whole system uses simulation technology to provide a solution for the application of UAV in the terminal distribution field as a decision reference.It can be used as a pre simulation link before regional layout,greatly reducing the risk and cost of promotion;At the same time,it can also provide reference scheme for operators in the industry before single task operation.
