DEVICE FOR COMPUTING OPTIMAL OPERATION PLAN AND METHOD FOR COMPUTING OPTIMAL OPERATION PLAN

摘要

The present invention is provided with an optimal-operation-plan-computing unit that computes an optimal operation plan including an optimal course on the basis of information inputted from an information-input-receiving unit, capability data pertaining to a vessel, and meteorological data pertaining to a course region through which the vessel navigates. The optimal-operation-plan-computing unit is provided with: a determination unit for determining, on the basis of the meteorological data, whether or not a nearby region close to a point of departure or a point of arrival is in a bad-weather state through which the vessel cannot navigate; and a constraint-condition-setting unit that, when it is determined that the nearby region close to the point of departure or the point of arrival is in a bad-weather state through which the vessel cannot navigate, sets as a constraint condition either that the vessel stops at a prescribed site for a prescribed period of time or that the vessel passes through the nearby region before the nearby region enters the bad-weather state. When the constraint condition is set, the optimal-operation-plan-computing unit computes an optimal course on the basis of the constraint condition.
