| Research Abstract |
In order to secure the natural resources and energies for Japan, we developed the logistics simulator with discretized models and time marching method. The simulator has some simulation models such as an ore carrier that transports iron ore by water from the port in a producing country to Japan's iron mills, a sea port with some capacity constraints, a stock yard of the iron mill and so on. The simulator can calculate not only shipping cost but also depleted risk evaluated from the stockpiles of each iron mill, so we can estimate the optimal shipping routes and fleet. Using this simulator, we found that the optimum routes was consisted of 30 % of the Japan?Australia?South America?EU combination route and 70% of the direct shuttle transportations routes.
