合理的空箱调运可降低班轮公司的营运成本、提高市场竞争力。针对班轮公司空箱调运问题,在对中国港口群分析的基础上,提出了基于融舱的中转调运策略。综合考虑运输成本、装卸成本、租赁成本和调运约束等条件,以最小化调运成本为目标,建立了在保证重箱运输前提下有中转的空箱调运整数线性规划模型。通过对模型求解,得到了比传统调运方式更为满意的调运方案,对结果进行分析制定出相应的调运策略。所建立的模型对空箱调运问题具有较强的指导意义。
Reasonable allocation of empty containers can reduce the liner company's operating costs and improve its market competitiveness. This paper analyzes the Chinese port and proposes a transit dispatching strategy in merging of cabins to deal with the allocation of empty transportation containers considering the transportation costs, handling costs, leasing costs and transporting constraints. The objective is to minimize transporting costs. This integer linear programming model allows transit of an empty container with the transport of heavy container under the premise. By solving the model we get a result better than the one obtained from that a traditional scheduling mode. In addition, we analyze the results and developed appropriate dispatching strategies. The model has a strong guiding significance for the empty container's reposition.
