In this paper , authors analysis the process of decision - making of collision avoidance , based on it the fuzzy decision - making method of ship collision risk is presented 摘要作者分析了船舶避碰的决策过程及已有的决策模型，提出了船舶碰撞危险的模糊决策方法。
It should be noted that the prediction of ship maneuvering motion is imported to the ship intelligent avoiding collision expert system , which is used to inspect the decision in ship collision avoidance 值得指出的是，本文将船舶操纵运动仿真模块引入智能避碰专家系统中，可以为船舶避碰决策提供检测。
Abstract : this paper analyses the necessity and urgency of exploitation of a marine collis ion - avoidance expert system . it specifies the thinking , scheme and the criterion of the software and makes a study of a mathematical model of risk degree 文摘:分析了航海避碰专家系统软件开发的必要性与紧迫性，并对整个软件开发的思路、方法及软件要求作了论述，同时建立了船舶避碰危险度的数学模型
The teaching quality of this course will determine the students " comprehension and application of the avoiding collisions rules . it also influences whether the crew can adopt the correct action in ship handling and the avoidance of collision 《船舶避碰与值班》教学的好坏决定了学生对避碰规则的理解与运用，影响船员在船舶操纵与避让中能否采取正确的行动，并最终影响碰撞事故的发生。
The system of the computer - assisted instruction and simulation for preventing collision is a multimedia courseware of research and development against above - mentioned situations and it aims at using the advanced teaching means to improve the teaching results 船舶避碰计算机辅助教学与碰撞局面模拟系统就是针对上述形势而研究开发的一个多媒体课件，旨在运用先进的教学手段，提高教学效果。
Although human beings have achieved a remarkable progress in maritime technology , maritime theories , marine instruments and equipments , up to now the problem of safely navigating unmanned ship along a planned route and preventing collision with encountering ships has not been satisfactorily solved 摘要迄今为止，无人驾驶船舶沿计划航向航行以及与相遇船舶避碰的问题未能令人满意地加以解决。
In case of ship collision , not only the hull is damaged , the goods is jeopardized , but also the ship and people are killed , and even the sea is polluted . the consequence is serious and it is the big misfortune of navigation 船舶碰撞，不但损坏船体、危及货物，甚至造成船毁人亡、海洋污染，其后果之严重、危害之大，堪称航海之大劫，船舶避碰及安全航行因此也一直是国际航海界关注的重要课题。
Automatic identification system ( ais ) provides a new means of collision avoidance for ships by utilizing its advanced communication method with high accurate information , which includes much information available for collision avoidance 船舶自动识别系统( ais ? automaticidentificationsystem )可利用其先进的通讯手段自动提供高精度信息，其中包含了许多可用于避碰的信息，为船舶避碰提供了一种新方法。
And then , to understand the sensitivity of the parameter in the mmg mathematical model to the maneuvering index , based on the above program , the author alter certain model parameters , then discuss the change of the maneuvering index , the sensitivity of the ma 另外，船舶操纵仿真在工程中有着广泛的应用背景，本文最后对船舶操纵仿真在船舶避碰、船舶过桥仿真和港口航道设计等工程领域中的应用进行了讨论。
Our studies present that neural networks will have good applications to water target detection - recognition - tracking based on radar and infrared and sonar technologies , and to information fusion for water traffic safety , and to making - decision for preventing collisions 研究分析表明，神经网络在水上目标的雷达、红外和声纳检测，识别，跟踪，水上交通安全信息融合，船舶避碰决策支持等方面，具有良好的应用前景。
