本研究通过单独最小化运输成本和库存成本来确定是通过枢纽运输还是直接到达目的地，从而制定了一个双目标模型。首先，制定了多港口停靠路线的运输和库存成本函数。运输成本包括资金和运营成本、燃料成本和港口费用，而库存成本包括等待时间成本和运输时间成本。然后，基于两种运输路线的运输成本和库存成本之间的权衡，确定了两目标模型的Pareto最优解，并在目标价值空间中进行了路线决策。给出了在每个库存成本水平下的最佳路线、船舶尺寸和出航频率。结果表明，随着始发港和目的港之间集装箱流量的增加，最优决策倾向于直接运输。
This study formulates a two-objective model by individually minimizing shipping costs and inventory costs to decide whether to route a shipment through a hub or directly to its destination. First, shipping and inventory cost functions are formulated for a multi-port calling route. Shipping costs include capital and operating cost, fuel cost and port charge, while inventory costs include waiting time cost and shipping time cost. Then, based on a trade-off between shipping costs and inventory costs for two types of shipping routes, Pareto optimal solutions of the two-objective model are determined, and a routing decision can be illustrated and made in objective value space. The optimal routing, ship size and sailings frequency with respect to each level of inventory cost is shown. The results show that the optimal decision tends to be direct shipping as container flow between origin and destination ports increases.
