摘　　要：为防止船舶在恶劣海况下出现横摇(参数)、谐摇和海损等风险,构建船舶在各种海况下的横摇(参数)和谐摇预估模型,提出一种基于船舶稳性和海况的多目标、多约束和多变量航行船舶航线优化模型。在此基础上,运用决策变量在时序和空间分布上的耦合特点作为先验基础理论,设计航行船舶的平滑航线。试验验证结果表明:该方法既能为船舶规划出合理的航线,使其绕开大风浪海区,又能防止船舶出现谐摇和横摇现象,提升船舶航行的安全性。To avoid navigation risks,based on a prediction model of ship rolling(parameters)and harmonic rolling under different sea conditions,a multi-objective,multi-constraint and multi-variable navigation optimization model is proposed.The smooth route is designed for a ship on basis of a priori basic theory that the decision variables are coupled in time series and spatial distribution.Tests show that safety navigation plan can be achieved by this model,avoiding areas of huge wind and wave and keeping ship stability.
