Abstract: To distinguish and refine the route and port choice of different types of goods, this paper takes the time value of goods as a type of transportation cost. The time value cost of goods is defined as the capital occupation cost and the loss of goods value. Considering the liner's timetable, transportation quotes and the time value of goods, this paper proposes the route choice model of port selection and the way and mode of port transportation. The case study of the Changsha-Durban using the depth-first traversal algorithm show that the liner schedule, transportation price, and the time value of the cargo would affect the choice of route. In terms of freight amplitude modulation, for high value and high time sensitivity cargo, the shipper's port selection has strong robustness. For low value and low time sensitivity goods, the amplitude modulation of freight quotation can be controlled (1000 USD·TEU-1 ) to realize the change of shipper's choice of multiple ports, which has relative flexibility and controllability.

Key words: integrated transportation, choice of exit port, depth first search, Sino- African multimodal transportation; time value of goods

摘要: 为区分细化不同货类的中非多式联运路径及出海港选择,将货物的时间价值作为一种运输成本。本文定义货物的时间价值成本由资金占用成本和货物价值损失两部分构成,考虑班轮的班期、运输报价及货物的时间价值,综合出海港的选择和到港运输路径、方式,构建路径选择模型,以期为实际的分货类出海港路径选择提供参考。通过深度优先遍历算法,求解长沙-德班算例。结果表明,班轮的班期、运输报价及货物的时间价值都将影响路径选择的结果。在运价调幅方面,对于高价值、高时间敏感度的货物,货主的出海港选择有较强的鲁棒性;对于低价值、低时间敏感度的货物,运费报价的调幅能在可控范围内(1000 USD·TEU-1 )实现货主对多个港口选择的变换,具有相对的灵活性和可控性。
