基于三级轴辐式的快递网络设计问题

Express Network Designing Based on Three-level Hub-spoke Network

在快递区域的城镇分布确定的枢纽节点的基础上,分配辐节点构建三级轴辐式快递网络,并以实现运输成本最小化为目标构建三级轴辐式快递网络模型。通过算例实验表明:三级轴辐式快递网络模型的有效性;预先确定一级辐节点数目对网络运输成本的影响;干线折扣因子变动对快递网络的影响。

Based on the hub and spoke distribution in the urban express service area, the three-level hub-spoke express network can be established by allocating the spoke nodes. The design is proposed to minimize the total network transportation cost. Three numerical examples results tried to demonstrate the effectiveness of the three-level hub-spoke express network model, the impact on variable transportation costs in this network by the given number of the first spoke, and the impact on express delivery network by the changes of discount factors in trunk network.
