【摘要】：为了打造高效、便捷的国际物流通道,同时提高消费者的生活水平,在"海运+冷藏班列+公路短驳"多式联运新业务模式下,文章提出了基于海铁联运的冷藏集装箱路径优化模型.文章以普通集装箱多式联运为基础,以包括制冷成本、运输成本、转运成本在内的总成本最小为目标函数建立模型.在算法上提出改进后的动态规划算法,把每个节点视为一段虚拟路径,通过算例分析得到在冷藏集装箱多式联运和普通集装箱多式联运两种情况下所得到的最优路径各不相同,冷藏集装箱在海铁联运的运输模式下,制冷成本虽然增加了,但总成本有所降低.研究冷藏集装箱海铁联运路径优化问题对决策者在选择运输路径时提供了可靠的参考依据.
[Abstract]:In order to create an efficient and convenient international logistics channel and improve the living standard of consumers, under the new multi-modal transport business model of "sea transportation refrigerated train road barge", This paper puts forward the route optimization model of refrigerated container based on sea and rail transport, which is based on ordinary container multimodal transport, including refrigeration cost and transportation cost. The minimum total cost including transshipment cost is the objective function to build a model. An improved dynamic programming algorithm is proposed in this paper. Each node is regarded as a virtual path. Through the analysis of an example, the optimal paths of refrigerated container multimodal transport and common container multimodal transport are different. The refrigeration cost of refrigerated container in the sea / rail transport mode is increased. But the total cost has been reduced. The research on the route optimization of refrigerated container seaborne railway transport provides a reliable reference for decision makers to choose the transport route.
