ON THE DEVELOPMENT OF ANTI-COLLISION SYSTEM AMONG SHIPS

本研究的主要目的是建立所有值班人员都能使用的防止船舶碰撞和搁浅的操作标准。首先，利用船舶操纵模拟器进行了一系列实验，获得了无地质约束海域船舶碰撞导航知识库；采用模糊推理理论对导航员的主观风险水平进行建模。在此基础上进行了一系列的模拟实验，以了解航海家对航道地理限制的主观风险水平。将这些知识库组合并包含在窄海峡航行仿真模型中。一系列的航海仿真验证了作业标准在船舶间、船舶与交通控制中心之间拥挤受限水域使用的有效性。为了支持船长和引航员的工作负荷和船舶交通中心对船舶航迹的监控，研究了给定航道地质条件下航道线的设置算法。将该算法建立的模型与海上观测的航线进行了比较，得到了较好的验证。该模型同样适用于评估海上大型建筑工程对海上交通的影响。

The main purpose of this studies is to establish the operational standard for preventing ship's collision and stranding that all watch officers are usable. At the first, a series of experiment using a ship handling simulator was carried out to get the knowledge base of navigator of collision between ships at sea area without any geological restrictions. The subjective risk level of navigator were modeled by Fuzzy reasoning theory.Then anther series of the simulator experiments were done to get the knowledge of navigator on subjective risk level on geographical restriction of water way. These knowledge bases are combined and included in a simulation model for navigation at narrow straits. A series of the nautical simulation verified the effectiveness of usage of operational standard at congested and restricted waters among ships and between on board and traffic control center.The algorithm for setting the course line under given geological restrictions of water way were developed to support the work load of captains and pilots and monitoring the ship track from vessel traffic center. The model based on this algorithm were well verified comparing with the course lines observed at sea. This model were also applicable to assess the influence of marine traffic due to large scale construction work at sea.
