摘要
海事事故通航环境风险动权量化模型研究是基于主观风险评价向客观风险评价的过渡阶段,涉及基于贝叶斯的事故特征通航环境因子量化、主观权重调整和客观权重调整等一系列建模过程。动权模型基于主观权重劣值倾向原则以及样本事故概率影响原则。针对通航环境定权风险评价的不足,从事故特征通航环境因子量化、主客观权重调整和事故案例分析对风险动权量化进行深入研究。研究结果表明:利用该模型进行案例分析可进一步明确航运事故风险机理,最终实现对事故风险预测和控制。
The weights of navigation environmental factors in a maritime risk analysis model should be dynamically adjusted towards an objective assessment as the analysis proceeding.The weights of factors are currently fixed based on experience in more or less subjective manner.The proposed modeling,instead,has the mechanism that the weights of environmental factors are chosen based on Bayesian analysis of accident characteristics,and adjusted in principle of objective assessment prior over subjective feeling,and taking sample accident probability into consideration.It proves that the proposed modeling analysis provides the better understanding of risk mechanism in objective assessment of maritime risks.
