摘　　要：为提高船舶避台的安全性和经济性,提出基于动态规划算法的船舶避台航线优化模型。选取一个对我国近海船舶航行安全造成严重影响的台风天气过程作为研究对象,以我国近海一艘实际运营的散货船的典型航线为例,充分考虑船舶在大风浪中的风增阻和波浪增阻及其引起的失速特征,得出台风动态移动过程中的船舶避台航时最短航线。仿真结果表明:优化航线可安全、动态地避开台风的大风浪区。In order to decide safe and economy route,the typhoon-avoiding optimization model is built based on dynamic programming algorithm.A typhoon,which harmed the offshore navigation safety severely,is picked as the typical condition,and a typical bulk carrier is chosen as the object ship.A typical voyage of the carrier is processed for optimization.The added wind resistance,the added wave resistance and the ship speed loss in the storm conditions are investigated.With the dynamic programming algorithm,the minimum-time route for avoiding typhoon is planed and automatically adjusted with the dynamic wind and wave environment.The simulation tests show that the optimized ship route can safely and dynamically avoid the typhoon storm area.
