摘要:

研究综合运输体系下的快捷货物运输网络资源配置优化问题。阐述快捷货运网络服务水平的内涵,提出物理服务水平和组织服务水平的概念,并分析快捷货物运输的组织模式。在此基础上构建综合运输体系下快捷货运网络资源配置数学优化模型,首次将综合运输枢纽选址和运输服务网络设计问题结合到一起,以枢纽定位来指导各运输方式下运输服务网络的构建。给出一种多阶段混合遗传算法对模型进行求解,该算法采用多个阶段间决策变量相互反馈的策略分解模型以便于算法的设计。通过仿真生成算例对模型和算法进行测试,并给出了灵敏度分析。

In this paper,the resource planning optimization for the multi-modal express shipment network was investigated.The concept and value of express shipment network service level,including physical service level and operation service level,were expatiated firstly.The organization mode of express shipment was analyzed.Then based on this,the mathematical optimization model for the resource planning for the multi-modal express shipment network was proposed.For the first time,the multimodal hub location and transportation service network design were combined together,where hub location will guide the design of the service network under different transportation modes.A multi-stage hybrid genetic algorithm was presented to solve the model.The algorithm leveraged the strategy decomposition model of mutual feedback of decision variable between multiple stages to facilitate the design of the algorithm.Based on the simulation data set,the numerical experiment and sensitivity analysis showed the efficiency and practicability of the methodology.
