为优化集装箱运输方案,提出干-支线的运输网络形式.基于综合成本最小原则,构建干-支线集装箱运输网络优化模型,寻找两个区域间优化的干-支线航线组合方案.优化的航线方案包括干线挂靠港及挂靠次序、支线数量和每条支线的运行方案.基于环渤海港口群和美国西海岸两个港口间的集装箱出发地-目的地(O-D)矩阵对模型进行测试,利用遗传算法对模型进行求解,得到该区间干-支线集装箱运输网络的具体形式.
In order to optimize the container transportation scheme, a dry-branch transport network is proposed.On the basis of the minimum cost of comprehensive cost, an optimization model of dry-feeder container transport network is constructed to find the optimal combination of dry-feeder routes between the two regions.The optimized routes include Trunk anchored ports and anchored order, the number of branch lines and the operation plan of each branch.The model was tested based on container departure-destination (OD) matrix between the two ports of the Bohai Sea Port Group and the West Coast of the United States, and the genetic algorithm was used to analyze the model To solve, get the dry-branch container transport network in the specific form.
