The invention relates to the technical field of navigation, and discloses an ocean vessel voyage number performance evaluation algorithm, which comprises the following steps of: in good weather, calculating a voyage distance of a vessel according to a time interval in two noon reports fed back by the vessel, obtaining corresponding meteorological data through a fed-back point location, and calculating the voyage number performance of the vessel according to the voyage number performance of the vessel; a flow factor is calculated according to the following formula: (float) Math.Cos (GetWayAngle (deg1, deg2)) * speed, speed is the flow speed, deg1 is the flow direction, deg2 is the bow direction, if the obtained flow factor is a positive number, the flow is forward flow, otherwise, the flow is reverse flow, and the weather is good as long as wind and waves do not exceed set values. The ocean-going ship voyage number performance evaluation algorithm is expanded to a method, a system and a computer program product for an ocean-going ship voyage number comprehensive algorithm, and the distance, the voyage time, the voyage speed, the oil consumption and the like of a ship in voyage number driving are analyzed and evaluated in various aspects according to ocean-going ship voyage number data. And real and reliable data analysis and evaluation are provided for the ship in ocean navigation, so that a captain can make the most correct decision.

    本发明涉及航海技术领域,且公开了远洋船舶航次性能评估算法,所述远洋船舶航次性能评估算法包括:好天气:针对船舶反馈的两次午报中的时间间隔计算船舶的航行距离,再通过反馈的点位拿到相应的气象数据,利用下式计算得出流因子:(float)Math.Cos(GetWayAngle(deg1,deg2))*speed其中speed是流速,deg1是流向,deg2是船首向,如得出的流因子是正数则是顺流,反之则是逆流,再结合风、浪只要不超过设定的数值就是好天气。该远洋船舶航次性能评估算法,扩展到用于远洋船舶航次综合算法的方法、系统和计算机程序产品,各方面根据远洋船舶航次数据来分析评估船舶在航次行驶中的距离、航行时间、航速、油耗等,给船舶在远洋航行中提供真实可靠的数据分析评估,供船长进行最正确的决策。
