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 organization mode of container transport in the upper reaches of the Yangtze River, this paper uses the Flexsim simulation software to simulate the container transport organization in the typical section of the Yangtze River.According to the container export trade in this section, the container transport organization optimization model is established. Algorithm to optimize the total cost of transportation and the ratio of ships by setting the experimental parameters and evaluation indexes.The results of the operation are in good agreement with the actual results.The transit mode has comparative advantages in three aspects: the total cost of the ship, the loading rate of the ship and the time of the container port pressure, However, the total transportation costs and average loading rates for both modes are almost the same.
