The invention discloses an expanded game decision-making method for ship collision avoidance in a cross encounter situation. The method comprises the following steps: acquiring a target ship in the cross encounter situation and basic information of a cluster in which the target ship is located; a method for determining the collision avoidance priority when the ship takes collision avoidance measures is provided; proposing a ship action set of game decision actions according to the collision avoidance priority; and according to the priority function and the action set, proposing a revenue function when the ships carry out collision avoidance gaming under the cross encounter situation by utilizing ship related parameters, and providing an optimal scheme for collision avoidance decision making of the ships on the sea by calculating the revenue function. According to the method, decision support is provided for collision avoidance gaming when the ships are in the cross encounter situation, meanwhile, reference value is provided for the ships to apply the expansion type gaming theory to the collision avoidance field, and it is effectively guaranteed that the most efficient collision avoidance measures can be taken in a short time when the ships are in the cross encounter situation.
一种交叉相遇态势下船舶避碰的展开式博弈决策方法,该方法包括:获取处于交叉相遇态势下的目标船舶以及目标船舶所处集群的基本信息;提出了船舶在采取避碰措施时的避碰优先级的确定方法;根据避碰优先级提出了博弈决策行动的船舶行动集;根据优先级函数以及行动集,利用船舶相关参数提出了船舶在交叉相遇态势下进行避碰博弈时的收益函数,通过计算收益函数为船舶在海上进行避碰决策提供优选方案。本发明为船舶处于交叉相遇态势下进行避碰博弈提供决策支持的同时,也为船舶将展开式博弈理论应用至避碰领域提供参考价值,有效保证船舶处于交叉相遇态势下可以在短时间内采取最高效化的避碰措施。
