Research On The Optimization Of The Delivery Network Of The D Delivery Center Of The Postal Branch Of W City

With the rapid development of China's e-commerce in the past 20 years,the scale of related express delivery continues to expand,the average unit price of express services continues to decline,the quality continues to increase,the competition of express companies further intensifies,and the market concentration also increases.According to data released by the State Post Bureau,in 2019,the average daily business volume and receipt of national express delivery companies reached 63.52 billion pieces and 749.78 billion yuan,an increase of 25.3% and 24.2% year-on-year.The gap between volume and revenue growth rate narrowed from 4.8% last year to 1.1 %,Industry homogenization competition is becoming increasingly fierce.Among the express companies participating in the competition,the growth rate of the "Tongda" is higher than the industry average,while the growth rate of the postal company,the earliest state-owned enterprise that provides express services,is only in the midstream.Facing the expanding market and fierce competition,How to further improve one's own competitiveness without being eliminated in the fierce competition has become a survival problem that postal companies urgently need to crack.For courier companies,optimizing delivery network operation management is a key aspect of solving this problem.Through optimization of delivery network operation management,delivery efficiency,service quality,and delivery cost can be further improved,thereby improving the competitiveness of enterprises.This article finds through the field survey of the existing delivery network operation status of the D delivery center of the W post branch that the D delivery center is also facing the practical dilemma of non-increasing revenue,low delivery service quality and unstable delivery team.Mainly caused by the poor operation and management of the existing delivery network,including the lack of a dedicated venue in the delivery distribution center,unscientific delivery road division and random delivery route without planning,etc.,it is urgent to optimize and improve the delivery network operation management of D delivery the center from these aspects.based on the study and analysis of various research theories of the existing center location and vehicle routing problem(VRP),this paper fully draws on these research results,combines the recent delivery operation data of D delivery center,and uses the center of gravity method to select location for The D delivery center,and the k-means clustering method to re-divide the D delivery center segment.Based on the Baidu map distance,the simulated annealing algorithm is used to optimize the delivery path of the new segment.Finally,the Through analysis and comparison of various key operating indicators of the delivery network of the D delivery center before and after optimization,it is concluded that the optimization can reduce the operating costs of the enterprise and the delivery time,thereby improving the service quality and competitiveness of the D delivery center.
