| With the rapid development of mobile Internet,the Internet second-hand trading platform is gradually improved with the maturity of e-commerce.From the comprehensive trading platform to the vertical fields of various categories,from the main form of C2 C trading to the C2B2 C model,the second-hand e-commerce is booming.Compared with C2 C model,C2B2 C model can effectively solve the trust problem in commodity transaction and improve transaction efficiency.Such platforms recycle goods,process them uniformly,and then sell them back to consumers.Such a process leaves the enterprise burdened with heavy assets and heavily dependent on the circulation of goods.And the construction of a suitable logistics network can play a role in maintaining the smooth circulation of goods,thus reducing the logistics cost.Therefore,this paper studies how to optimize the logistics network to save the circulation cost of enterprises.This paper considers the key role of the platform enterprises in the C2B2 C model.Based on the hub node characteristics in the hub and spokes network,it optimizes the existing logistics network to find out the number and location of nodes that can be upgraded to hubs,and to determine the connection relationship between radiating nodes and hub nodes.Based on the theory of hub-and-spoke logistics network,this paper studied the key characteristics of the platform enterprises in the C2B2 C model.Based on the assumption of unlimited capacity,a model of multi-hub single-distribution pure hub-and-spoke logistics network was constructed.The gravity model was introduced to obtain partial parameter data,and the Lingo and Cplex were used to solve the model.The research results of this paper have important application value for the construction and optimization of the logistics network model of the second-hand e-commerce platform of the Internet using the C2B2 C model,so as to reduce the circulation cost and improve the competitiveness of enterprises. |
