To provide a navigation avoidance support device capable of automatically deriving an optimum navigation avoidance operation method corresponding to steering performance of a ship.SOLUTION: A preference degree calculation section 24 calculates a preference degree expressing subjective preference of a ship operator associated with selection of respective positions for each position of a navigation avoidance operation space (space where a choice of a veering angle is combined with a choice of a speed change ratio). A danger degree calculation section 26a assumes a state of an own ship after a predetermined time from a present point of time by reflecting a steering performance parameter expressing steering performance of the own ship, and calculates a degree of collision danger with respect to another ship in a case where the own ship performs a navigation avoidance operation under the state for each position of a navigation avoidance performance space. A utility value calculation section 20 calculates a utility value by subtracting a degree of collision danger from the preference degree for each position of the navigation avoidance operation space. An operation instruction section 23 instructs an operation method of the own ship so as to meet a route in a case where the navigation avoidance operation based on a calculation result of the utility value calculation section 20 is performed under a state after a predetermined time.SELECTED DRAWING: Figure 1

    【課題】船舶の操縦性能に応じた最適な避航操船方法を自動的に導出可能な避航支援装置を提供する。【解決手段】選好度算出部24は、避航操船空間(変針角の選択肢と変速率の選択肢とを組み合わせた空間)の各位置毎に、各位置の選択に伴う操船者の主観的な好みを表す選好度を算出する。危険度算出部26aは、自船の操縦性能を表す操縦性能パラメータを反映して現時点から所定時間後の自船の状況を仮定し、当該状況下で自船が避航操船を行った場合の他船に対する衝突危険度を、避航操船空間の各位置毎に算出する。効用値算出部20は、避航操船空間の各位置毎に、選好度から衝突危険度を減算することで効用値を算出する。操船指示部23は、効用値算出部20の算出結果に基づく避航操船を所定時間後の状況下で行った場合の航路に乗るように、自船の操船方法を指示する。【選択図】図1
