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.
