集装箱航线资产配置鲁棒优化模型

研究了不确定条件下集装箱航线资产配置问题.根据集装箱航线运行的基本特点和要求,基于航线均衡运行原理,建立了集装箱航线资产配置确定性模型,优化船舶规模、集装箱配置与舱位分配.通过引入鲁棒优化理论,将此模型拓展为包含不确定因素的鲁棒优化模型,以船舶规模为设计变量,以舱位分配为控制变量建立分析模型.以钟摆型航线为例进行仿真实验,对模型的有效性进行了验证.结果表明,该模型既考虑了需求的不确定性影响,又考虑了解与模型的鲁棒性,并且体现了决策者对风险的厌恶程度,使模型结论更符合实际需要.

Robust optimization model for asset deployment in a container shipping line

Asset deployment in a container line experiencing uncertainty was studied.After considering the characteristics and requirements of a container line,a deterministic model for the problem was developed based on the equilibrium principle.The objective was to optimize ship size,the number of containers,and slot allocation.The deterministic model was expanded to a robust optimization model that considers uncertain factors.Ship size and slot allocation were treated separately as design variables and control vari...
