| 摘 要： | 鉴于恶劣海况将引起船舶失速、剧烈横摇甚至倾覆,为避开恶劣海况区域,提出一种考虑复杂气象变化的智能船舶动态航线规划方法。通过改进A*算法的启发式函数,将风、浪对船舶失速的影响加入路径代价值的估算中,进而规划出一条避开恶劣海况的动态航线。跨北大西洋的航线规划仿真结果表明:本文提出的动态航线规划方法可以将船舶的跨洋航行时间缩短18.17%,并且能有效地避开风浪较大的危险海域。运用该动态航线规划方法能缩短船舶航行时间,节约航行成本,提高航运企业的经济效益。

| Abstract: | In view of the fact that the severe sea conditions will cause ships to
stall, roll violently and even capsize, in order to avoid the severe sea condition
areas, an intelligent ship dynamic route planning method that takes into account
complex meteorological changes is proposed. By improving the heuristic function of
the A* algorithm, the influence of wind and wave on ship stall is added to the
estimation of the path cost value, and a dynamic route to avoid severe sea
conditions is planned. The simulation result of the route planning across the North
Atlantic shows that the application of the dynamic route planning method proposed
in this paper can shorten the sailing time of ships across the ocean by 18.17%, and
can effectively avoid the dangerous sea areas with large wind and waves. Using this
dynamic route planning method can shorten the sailing time, save the shipping cost,
and improve the economic benefit of shipping companies. |
