The Mode Of Joint Distribution For Urban Commercial Logistics And Vehicle Route Planning

With the continuous improvement of people's living standards,people's pursuit of a better life and consumption experience is not only reflected in the availability of goods,but also reflected in the timeliness and convenience of consumer services and other higher-level needs,which puts forward new and higher requirements for urban commercial logistics distribution.As an important carrier of urban commercial circulation function,transaction market is an important guarantee for the daily life of urban residents.However,with the acceleration of urbanization process,in order to ease and optimize the functions of core urban areas,the large-scale transaction market and professional wholesale market in the central urban areas have become the mainstream trend.However,after the exchange market moved out,the strong consumption demand in the city could not be satisfied in time.In order to meet the needs of consumers,distribution enterprises and commercial enterprises take advantage of the empty factories,old warehouses,underground garages and even residential houses as their own transit warehouses.This approach can not fundamentally solve the problem of urban distribution,but also has great hidden danger of prevention and control.Therefore,whether from the improvement of people's life quality or from the efficiency of logistics distribution,we need to improve the existing distribution mode and distribution network system.This paper mainly studies the mode of unified warehouse distribution of urban commerce logistics and the problem of vehicle path selection under this mode.In view of the real contradiction that the current large-scale trading market moves out and the demand of urban internal logistics distribution increases sharply,this paper puts forward the idea of selecting and configuring the shared warehouse in the city,so as to build the distribution network of the shared warehouse and implement the unified warehousedistribution.At the same time,the model of freight mixed vehicle path planning considering customer satisfaction is established,and the solution model of single parent genetic algorithm is designed.Through the corresponding calculation example and using MATLAB software,the validity of the model is verified by comparing with the commonly used scanning method of small and medium-sized logistics enterprises.The main contents of this paper are as follows:First of all,this paper analyzes the existing problems of the distribution mode from three perspectives of social macro,urban meso and enterprise micro,and puts forward the necessity and significance of carrying out the joint distribution mode of unified warehouse.Then,combined with the relevant theories of shared logistics and joint distribution,and based on the research status of urban distribution mode and vehicle path planning,three kinds of joint distribution modes with different sharing degrees are designed,and the distribution network system based on shared warehouse is constructed.At last,according to the reality of the mode,the paper constructs a cargo mixed load path planning model considering customer satisfaction,and designs the judging process of cargo mixed load relationship,and uses single parent genetic algorithm to design the algorithm,and at the same time,combines with the calculation of an example to test.
