【摘要】 分析船舶领域和动界的研究现状.在研究船舶碰撞危险度的基础上,建立船舶动态避碰行动领域模型.该模型为船舶自动避碰决策系统提供依据,并能直接指导航海人员的避碰行动.其领域边界随碰撞危险度阈值的不同而变化,对于碰撞危险度为零的船舶,该领域不存在.最后,通过实例说明避碰行动领域模型的应用.更多还原

【Abstract】 The present situation of ship’s domain and arena is analyzed. Based on ship’s collision risk index (CRI), a dynamic domain model for ships to avoid collision is put forward. This model is for the ship’s automatic collision avoidance system and can be used to guide the navigator’s behavior. The ship’s domain is changed with a selected critical value of CRI. For a target ship with CRI equals to zero, its domain does not exit at all. At the end of this paper, an example is given to illustrate the application of this model.更多还原
