摘　　要：为减少船舶碰撞事件,实现宽阔水域中多船避碰,以本船作为让路船,应用DCPA和TCPA加权法计算船舶会遇危险度,采用避碰重点船的方法分析多船会遇的影响因素,生成有效的行驶路线.为获得不同海况下多船(会遇的)避碰模拟,分别模拟四船不同起点、不同航速会遇,并比较四船会遇和三船会遇时船舶航行路线.结果表明,该方法可以使船舶安全避碰,证明了不同数量的船舶会遇时均可以智能寻找路径.To reduce the ship collision occurrence and achieve multi-ship collision avoidance in broad areas,DCPA and TCPA weighting method were used to calculate shipping risk by taking own ship as the give-way vessels.Effective factors of multi-ships encounter situation were analyzed by using avoidance key ship to generate an effective route.Four simulation schemes with this method were used to find a safe and automatic route,which includes different initial points and various speeds.Comparing four ships＇ traveling path with those of three ships＇,the safe and smart collision avoidance solution of different situations is presented.
