集装箱航线结构模式的选择

Choice of the container line structure mode

针对不同船型,研究基本港航线结构模式和核心港航线结构模式适宜选择和优化转化.提出以航次单位时间投资收益为度量的解决思路,运用数学分析方法构建两种航线结构模式的运行模型和优化转换的条件要求.以东北亚至美国西海岸贸易区域航线为例,运用Matlab编程进行求解,获得现行市场状况下,不同船型对航线结构模式选择的适宜性和相互转换的优化船型,验证了本文提出的思路和设计的模型具有很好的实用性.

Appropriate selection and optimization-conversion between the base-port structure mode and the hub-port structure mode were studied considering the different ship sizes.Choosing the unit-time per ship-slot profit as the basic standard,operating models of the two shipping structures and their requirements of optimization-conversion via mathematical analysis method were established.Taking the line from northeast Asian to west coast of American as example,the optimal mode under the given ship size was obtained and the balanced ship size was got by programming with the Matlab software,which proves that the optimized model agrees well with practice.
