PROBLEM TO BE SOLVED: To predict a vessel arriving in a target sea area within a fixed period of time from a time designated before the arrival in the target sea area.SOLUTION: The processor executes acquisition processing for acquiring a series of time-sequential data indicating the time-sequential position and time of a vessel traveling to a target port within a target sea area until its arrival at the target port, and specification processing for specifying the position of the oldest time-sequential data among the time-sequential data of the series of time-sequential data at which the vessel can enter the target sea area within a prediction period as the farthest position of the vessel from the target sea area based on two continuous time-sequential data among the series of time-sequential data acquired by the acquisition processing, arrival time indicated by the time-sequential data among the series of time-sequential data when the vessel is positioned at the target port, and the prediction period.SELECTED DRAWING: Figure 2
【課題】対象海域への到達以前の指定された時刻から一定期間内に対象海域に到着する船舶を予測すること。【解決手段】プロセッサは、対象海域内の目的港へ航行する船舶の前記目的港に到着するまでの時系列な位置および時刻を示す一連の時系列データを取得する取得処理と、前記取得処理によって取得された一連の時系列データの中の連続する2つの時系列データと、前記一連の時系列データのうち前記船舶が前記目的港に位置するときの時系列データが示す到着時刻と、予測期間と、に基づいて、前記一連の時系列データのうち前記船舶が前記予測期間以内で前記対象海域に進入できる時系列データの中の最古の時系列データの位置を、前記対象海域からの前記船舶の最遠位置として特定する特定処理と、を実行する。【選択図】図2
