The Intelligent Scheduling Research Of Logistics Distribution Vehicle Based On Multi-Agent

With the development of market economy,the logistics,that was said "third profit source," is making great impact on economic activities and increasingly cause the enterprise's concern and attention,becoming one of the current "the most important areas of competition".In the field of logistics research,vehicle scheduling and distribution problems have always been the focus of theoretical research and practical work.Vehicle scheduling is a complex combination optimization problem involving multiple targets and constraints.The arrangement of distribution vehicles and the rationality of line planning have a great influence on the delivery time,distribution cost and the quality of the whole distribution.How to use scientific and reasonable method to plan distribution lines,related to the logistics system optimization,which is the core of the scheduling,but also a problem.In recent years,the development of various information technology has paved the way for the intelligent scheduling of logistics distribution vehicle.Agent,as a typical representative of the artificial intelligence fields,with the intelligent,distributed,dynamic and other characteristics,to perceive the external environment and its own changes,and produce the corresponding action.In the multi-agent system,each agent has a certain independent function,and the structural relationship between agents is dynamically adjustable.The architecture together with different function agents is adaptive,self-organized and good coordination.It is very suitable for solving the scheduling problems of logistics distribution vehicle,and can complete complex overall operation through coordination.In the paper,firstly expound the background,significance and related research status.On the basis of a lot of theoretical research,the structure model of vehicle scheduling system based on multi-agent is designed,including system layer,structure layer and function layer.By analyzing the communication and cooperation between agents in the system,the process of vehicle scheduling is clarified.On the base of former research,the model and algorithm of the vehicle scheduling problem are researched for the vehicle dispatching agent in the structural model.Then the mathematical model is established and the simulated annealing algorithm is used according to the characteristics of the model,and the validity of the model and the algorithm is verified by an example.Finally,the paper introduces the structural model of vehicle scheduling system,and combines the mathematical model and algorithm of vehicle scheduling problem based on Anylogic simulation software.The simulation results show the feasibility of agent technology's application in the field of vehicle scheduling,that has certain theoretical and practical significance.
