摘要
Abstract
Hub-and-spoke express networks achieve economies of scale by integrating express resources between hubs,and transportation costs can also be reduced.However,the agglomeration effect at the hub also makes it the most likely congested node in the network.When constructing an express network,it is necessary to optimize the basic layout of the network under cost control and design a resource-balancing strategy to alleviate the regional congestion of the network and further improve the network's reliability.Based on this,a two-phase decision-making method is constructed,where the first phase considers transportation costs for the decision of hub location.The second phase implements a resource-balancing strategy to alleviate congestion.The congested cargo flows are redistributed,and transportation is detoured to hubs with residual resources.A hub-and-spoke express network covering central-eastern China is constructed utilizing the two-stage decision-making model.In the study case,the resource balancing strategy reduces the number of congested hubs by 20%-67%,the variance of the resource utilization of the hubs decreases,and the resource balancing level of the network increases.The above case study results validate the effectiveness and application value of the two-phase decision-making method.关键词
