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.
According to different types of ships, it is necessary to study the mode of basic air route structure and the mode of core harbor route structure to select and optimize the transformation.A solution to the problem of investment return per unit time is put forward, and two operational models of route structure model and optimization The conditions of the conversion.According to the trade routes between Northeast Asia and the United States west coast, this paper uses Matlab programming to solve the problem, and obtains the optimal ship model of suitability and mutual conversion of different ship types for the route structure mode under the current market conditions. The idea and design of the model has good practicality.
