国内物流システムに適合する船舶とその運航方法の設計に関する研究

国内分配制度是支撑我国经济和社会福利的重要基础。该研究计划提出了方法，以确保新引入的海上运输系统相对于其他陆地和空中系统的可行性。基于竞技场软件编制了仿真程序，仿真中的模态选择基于牺牲模型。通过物流数据分析，计算了货物的时间价值和货物在一天内的外观分布。并假设货物将选择牺牲最小的方式。船舶基本设计系统准确地确定了海上运输成本。海上系统的有效性取决于船舶的设计，即大小，速度，范围和其他人，也取决于操作的时间表。该系统适用于与卡车，铁路和飞机发生冲突的东京-北海道航线。通过仿真，船舶在夜间以30节的速度航行时，具有很强的竞争力。并将此结果作为一个项目，采用折现现金流量法进行了评价。本文所开发的系统对于解决铁路运输中的其他方面的问题，如如何提高铁路运输的效益等，具有一定的参考价值。

The domestic distribution system is an important base, which supports economy and the public welfare of our country. The research program proposed the methodology to make sure of the feasibility of the newly introduced marine transportation system with respect to other land and air based systems. Simulation program was implemented based on the ARENA.The modal selection in the simulation was based on the sacrifice model. The time value of the cargo and distribution of the appearance of the cargo in a day were measured by the logistic data analysis. And it is assumed that the cargo will choose the least sacrifice mode. The cost of the sea transportation is accurately determined by the ship basic design system. The effectiveness of sea systems depends on the design of the ship, that is, the size, speed, range and others and also on the timetable for the operationThis system was applied to Tokyo-Hokkaido route, which has the conflict with the trucks, railways and aircraft. By this simulation, Ship becomes very competitive when they can operate at night in the speed of 30knots. This result is also evaluated by the discount cash flow method as a project. The high-speed service at night with a small number of the ship is most feasible.The developed system is available to see other aspects of the problem, for example, how to improve the profit of the railways.
