考虑拥塞成本的B2C配送网络成长模型

A Growth Model of B2C Distribution Network Considering Congestion Costs

为了解决基于电子商务的大规模配送网络的构建问题,以电商企业自营物流模式下的B2C配送网络为研究对象,利用复杂网络理论,构建了考虑拥塞成本的大规模配送网络成长模型.在选择节点与新增节点建立连接时,以节点度、运输成本和拥塞成本为依据.仿真结果表明:与不考虑拥塞相比,该模型能够使无拥塞节点或者拥塞程度较轻的节点获得较大的优先连接概率,从而有效地降低整个配送网络的总成本.

How to build a large-scale distribution network that serves the e-commerce is a difficult prob- lem. In this paper, with a B2C distribution network of an e-commerce enterprise with self-run logistics as the research object, using complex network theory, a growth model taking into account congestion costs for the large-scale distribution network was constructed. Network growth depends on the increase of new nodes and connections between the nodes generated to meet the logistics needs of new online shopping. Node degrees, transportation costs and congestion costs are the basis of selecting an original node to connect with a new node. The simulation results show that ： compared with the situation of ignoring congestion, this model can make the nodes which have no congestion costs or lower congestion costs obtain a larger priority connection probability, thus the total costs of the entire distribution network can be effectively reduced.
