Research On Optimization Of Distribution Network Of D Express Company In Shijiazhuang City

The vigorous development of the Internet and e-commerce economy,and the continuous improvement of the construction of the logistics distribution system have promoted the rapid rise of China's express delivery industry.As an important link in the operation and management of express delivery companies,the distribution network directly faces and serves customers,and is closely related to the work efficiency,management capabilities,service level and customer satisfaction of the express delivery company.Therefore,optimizing the delivery network of the express delivery company can improve the market competitiveness of the company.,Expanding the scale of the market and responding to the complex and volatile market environment has played a vital role.This article takes D express company's Shijiazhuang urban distribution network as the research object,obtains relevant data information through field research,and deeply analyzes the problems of D express company's Shijiazhuang urban distribution network.Combined with the actual situation of D Express Company in Shijiazhuang urban area,in view of the unreasonable distribution of business outlets,fully consider the operation of each business outlet and the express delivery needs of the customers responsible for determining the need to cancel,split and add new business outlets to business outlets With the strongest operating capability and the highest customer satisfaction,the location model of business outlets is built for the goal,and the best location for splitting and adding new business outlets is determined through the use of immune algorithms and MATLAB programming.In response to the problem of idle service capacity of intra-city express sorting centers,four intra-city express sorting centers were integrated,and the best location for intra-city express sorting centers after the integration was determined by using the center of gravity method.In view of the unreasonable division of the management scope of some business districts,the management scope of the four business districts was re-divided by using the K-means clustering algorithm based on the original business outlets and the split and the coordinate positions of the newly added business outlets.Aiming at the unreasonable problem of intra-city express delivery route planning,the intra-city express delivery route optimization model was established with the goal of minimizing the sum of transportation costs,time penalty costs,and cargo damage compensation costs incurred by intra-city express services,and re-planning was solved by using genetic algorithms and MATLAB programming.Express delivery routes in the same city.The research content has certain guiding significance for optimizing the Shijiazhuang urban distribution network of D Express Company and enhancing the company's market competitiveness and economic benefits.
