To provide an optimal shipping schedule calculating device and an optimal shipping schedule calculating method that can automatically settle on a suitable route in further accordance with the actual condition.SOLUTION: An optimal shipping schedule calculating device comprises an optimal shipping schedule calculating unit that calculates an optimal shipping schedule including an optimal route on the basis of information input from an information input receiving unit, ship performance data, and weather data in a route area where the ship travels. The optimal shipping schedule calculating unit includes: a determination unit that determines whether an area in the vicinity of the departure place or the destination is in bad weather in which the ship cannot travel on the basis of the weather data; a constraint setting unit that, when the area in the vicinity of the departure place of the destination is determined to be in bad weather in which the ship cannot travel, sets, as a constraint, the ship stopping at a predetermined point for a predetermined time, or the ship passing through the vicinity area before the weather in the vicinity area gets bad. When the constraint is set, the optimal shipping schedule calculating unit calculates the optimal route on the basis of the constraint.SELECTED DRAWING: Figure 2
【課題】より実情に即した好適な航路の策定を自動的に行うことができる最適運航計画演算装置および最適運航計画演算方法を提供する。【解決手段】情報入力受付部から入力された情報と、船舶の性能データと、船舶が航行する航路領域の気象データと、に基づいて、最適航路を含む最適運航計画を演算する最適運航計画演算部と、を備え、最適運航計画演算部は、気象データに基づいて、出発地または到着地の近傍領域が、船舶が航行不能な天候不良状態であるか否かを判定する判定部と、出発地または到着地の近傍領域が、船舶が航行不能な天候不良状態であると判定された場合、船舶が所定地点で所定時間停止すること、または、近傍領域が天候不良状態となる前に船舶が当該近傍領域を通過すること、を拘束条件として設定する拘束条件設定部と、を備え、最適運航計画演算部は、拘束条件が設定された場合、当該拘束条件に基づいて最適航路を演算する。【選択図】図2
