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。该研究计划提出了一种方法，以确保新引入的海洋运输系统相对于其他陆基和空基系统的可行性。基于ARENA实现了仿真程序。仿真中的模态选择基于牺牲模型。通过物流数据分析，测量货物的时间价值和货物在一天内的出现分布。并假设货物将选择最小牺牲模式。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，航程等，也取决于作战时间表。该系统应用于东京-北海道航线，这与卡车，铁路和飞机有冲突。通过这种模拟，舰船可以在夜间以30节的速度运行，具有很强的竞争力。这一结果也通过折现现金流量法作为一个项目进行评估。以少量船舶进行夜间高速服务是最可行的。系统的发达也让我们看到了其他方面的问题，比如如何提高铁路的利润。

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.
