基于可靠性的集装箱班轮轴辐式网络设计

Reliability-based Design of Container Liner Hub-and-spoke Network

对集装箱班轮运输航线网络的可靠性进行了研究,同时解决枢纽港选择、支线港配置和备选枢纽港选择三个问题。在模型中引入决策备选枢纽港的变量,并设置枢纽失灵产生的惩罚成本。设计算例进行分析,结果表明每个枢纽港都能够找到相应的备选枢纽港,作为应急预案,有效地提高了航线网络的可靠性,提升了班轮公司对突发事件的响应能力,弥补事后干扰恢复的被动性和高成本。算例验证了模型的可行性,可辅助班轮公司在航线网络规划阶段进行决策,并为海运网络可靠性的研究提供借鉴。

In the design of the shipping route network,the key to the successful completion of shipping tasks is whether the hub port can operate normally.Susceptible to emergency events such as adverse weather,natural disasters,and labor disputes,etc.,once disturbed,the hub port should be replaced by an alternative hub port in terms of transportation tasks and services.Based on this consideration,this paper studies the reliability of the container liner shipping route network,and attempts to solve the three issues of hub port selection,feeder port deployment and alternative hub port selection.It first introduces the declsion-making variable for the selection of the alternative hub port in the model and set the penalty cost in case of hub failure.Next a numerical example is used,the result of which shows that each hub port can correspond to an alternative hub port as its contingency plan,which can effectively improve the reliability of the shipping route network and the liner company's responsiveness to emergencies,and make up for the passivity and high cost due to ex post interference or recovery.
