摘要: 在大风浪天气条件下, 为了使救助船在能够保障自身安全的前提下, 尽早靠近遇险目标实施救助, 采用专家问卷调查的方式, 得到了北海救助局主力救助船的失速情况、航行风压差与风险等级隶属度等数据。根据模糊数学和风险分析理论, 建立了救助船的风险评估模型, 提出了基于电子海图的大风浪信息综合显示与救助船舶航线优选平台的功能需求, 优化了航线风险评估流程, 并设计了大风浪天气条件下海面遇险目标快速接近辅助决策系统。仿真结果表明: 距离遇险目标最近的救助船北海救196航线风险等级过大, Ⅲ级风险的隶属度为1.0;救助船北海救108沿2号航线前往遇险目标时, 会遭遇8级横风, Ⅲ级风险的隶属度为0.5, 失速明显且航行时间过长; 救助船北海救113的1号航线安全性较佳, 时间最短, 为最佳航线。仿真结果与实际结果一致, 可见, 系统有效。Abstract: Under heavy weather condition, in order to make rescue ship approach distress target and implement assistance while the self-security of rescue ship could be guaranteed, the method of expert consult survey was used, and the stall situations, navigation leeways and risk grade membership degrees of brunt rescue ships in Beihai Rescue Bureau were obtained.Based on fuzzy mathematics and risk analysis theory, the risk evaluation model of rescue ship was set up, the functional requirements such as the integrated display of heavy weather information and the optimal route platform of rescue ship based on electronic chart were carried out, the evaluation process of route risk was optimized, and the quick approaching assistant decision system of distress target on sea surface under heavy weather condition was designed.Simulation result indicates that though BHJ196 is the nearest rescue ship to distress target, the route risk is too large, and the membership degree of Ⅲ-grade risk is 1.0.While approaching distress target by No.2 route, BHJ108 will encounter 8-grade crosswind, the membership degree of Ⅲ-grade risk is 0.5, stall situation is significant, and navigation time is too large.The safety of No.1 route for BHJ113 is better, and navigation time is the least, so the No.1 route of BHJ113 is the optimal route.The simulation result is consistent with the actual result, so the proposed system is effective.
