考虑集疏运均衡与空箱调运的内支线航线网络设计优化

    Optimization of domestic feeder container liner routes design considering consolidation balance and empty container transshipment

    • 摘要: 为了解决集装箱内支线运量结构差异以及航线结构单一,导致载箱率偏低与集疏运成本居高不下的问题,基于某集装箱枢纽港集疏运驳船运输网络的作业数据,提出了直达航线与环绕式航线结合的混合航线模式。在该模式下,将支线港按照航程距离进行聚类分析,并以集运与疏运均衡、重箱运输与空箱调运均衡为目标构建航线设计优化模型,通过小规模问题求解精确解验证模型,进而设计启发式算法求解现实规模问题。通过将提出的混合模式与现有直达航线模式进行运力需求对比分析,验证了混合航线模式可减少集疏运网络运力浪费,可为内支线航线网络设计提供决策参考。

       

      Abstract: For container feeder transportation, the differences in the volume structure of feeder ports and the single route structure always result in structural low container load factor and high cost of consolidation and transportation. Based on the operation data of the collection and evacuation barge transportation network of a container hub port, a hybrid route model combining direct routes and wrap-around routes is proposed. Under this model, the feeder ports are clustered according to the voyage distance, and the route design optimization model is constructed based on this model with the objectives of balanced consolidation and evacuation as well as balanced transportation of heavy containers and empty containers, the model is validated by solving the exact solution of the small-scale problem, and then heuristic algorithms are designed for solving the realistic scale problems. By comparing the proposed hybrid mode with the existing direct route mode, it is verified that the proposed hybrid mode can reduce the waste of capacity in the transportation network and provide a reference for the design of domestic feeder route network.
