Kesearch On Analysis And Optimization Of Terminal Delivery

Along with the great development of internet shopping,the express delivery services also a quick growth.Because of the business growth and diversified demands,the issues on terminal delivery appeared.The cost of terminal delivery is more than other parts,and it's close to the customers,hence this is the most important cycle that all the service providers focus on and the one needs to be optimized urgently.This paper aims at "last mile”deliveries,according to the investigation and statistics analysis of the consumers'(hereinafter referred to as customers')demands on terminal delivery,based on fulfilling customers demands,analysis the advantages and disadvantages of current delivery mode.Raise the idea of new terminal delivery mode that separating the delivery part and the pickup part.Specifically,the main researches are as follows:First,through reading documents and reports,systematically analyse the terminal delivery situations and the delivery modes,both in China and abroad.The analysis contains terminal delivery environment,customers demands,modes applicability,the advantages and disadvantages.Come to the conclusions that currently Directly deliver(DD)and Self-service Pickup(SP)are the two modes used most,by using this as the theoretically references.Secondly,starting from the actual problem,use the method of combining theory with investigation to analyze,classify and optimize delivery service provider,customers,terminal delivery demands.By issuing the paid Internet questionnaire,visit Haidian District delivery service company B personally to collect reliable data information and do cross-tabs and clustering analysis.According to the characteristics of regional features,the customers job characteristic,to provide data basis for the terminal delivery mode that separating the delivery part and the pickup part.And confirm the cost,factors of terminal delivery,then provide optimize rules and plans.Based on the actual research and the existing optimization theory,raise the optimization model,that is the minimum cost in the terminal delivery model(the model of separating directly deliver and self-pickup in terminal delivery).From the perspective of demand,judging the delivery of demand with distance,meet the demand of regional customers at the same time,reduce the secondary delivery rate,total delivery cost reduced.Based on the current Self-service Pickup mode has the advantages of obvious economies of scale,cost savings,improve the efficiency,therefore under the condition of meet customer needs,as far as possible will apply the Self-service Pickup mode.The model sets apart DD and SP,the two modes of delivery,and applies the two-layer method of genetic algorithm.Last,test the mode s accuracy and calculations' efficiency.The examples proved that the cost of this delivery mode decreased 23%than the traditional one.
