长江上游集装箱运输组织优化研究

Optimization research on container transport organization of upper Yangtze river

为科学评判和优化长江上游集装箱运输组织模式,利用Flexsim仿真软件对长江典型区段集装箱运输组织进行系统仿真.结合该区段集装箱外贸出口情况,建立集装箱运输组织优化模型.使用Flexsim自带的优化算法,通过设置实验参数和评价指标,优化运输总成本和船舶配比,运行结果与实际吻合.中转模式在船舶投入总成本、船舶航次装载率及集装箱压港时间三个方面均具有比较优势,但两种模式的运输总成本和平均装载率相差无几.

In order to scientifically evaluate and optimize the container transport organization mode of upper Yangtze river, the typical segment of Yangtze fiver container transport organi- zation mode was simulated by Flexsim simulation software. Combining with the exports of upper Yangtze container, the upper Yangtze container transport organization model was es- tablished. The Flexsim simulation tester was used, and the total transportation cost and the ratio of the ship were opti- mized by setting the experimental parameters and evaluations. The results of transport organization system coincides with that of the actual situation. Transit mode has a comparative advan- tage on aspects of vessel cost, voyage loading rate and waiting time in port, but the differences between the two modes on to- tal cost and average loading rate are very small.
