The invention discloses a ship navigation risk assessment and decision support method and system. The method comprises the steps that a ship navigation area is expressed as a to-be-assessed area, navigation information and historical accident data of the to-be-assessed area are acquired, key risk factors influencing ship navigation safety are determined based on the navigation information, and the key risk factors are classified; building an accident scene based on the classified key risk factors and historical accident data, evaluating the accident scene, calculating a risk value of the evaluated accident scene, and dividing the accident scene into different grades according to the risk value; and constructing a risk control operation flow chart, and determining a risk value of the to-be-evaluated area based on the risk control operation flow chart and the accident scene. The method is suitable for risk assessment of different scales and complexities, the risk is comprehensively and accurately assessed, meanwhile, adaptability and flexibility to variable environments are kept, and the navigation safety performance and effect are improved.
本发明公开了一种船舶航行风险评估与决策支持方法及系统,包括将船舶航行的区域表示为待评估区域,获取待评估区域的航行信息和历史事故数据,基于航行信息确定影响船舶航行安全的关键风险因素,对关键风险因素进行分类;基于分类后的关键风险因素和历史事故数据构建事故场景,对事故场景进行评估,计算评估后的事故场景的风险值,根据风险值将事故场景划分为不同的等级;构建风险控制操作流程图,基于风险控制操作流程图和事故场景确定待评估区域的风险值。本发明适用于不同规模和复杂度的风险评估,全面准确地评估风险,同时保持了对多变环境的适应性和灵活性,提升了航行安全性能和效果。
