基于船舶破损安全性的舱室优化方法

Cabin optimization method based on damaged ship safety

[目的]船舶安全性是船舶最重要的性能之一,而舱室优化与提高船舶破损安全性密切相关,二者之间的关系是一个复杂的多因素问题。[方法]基于SOLAS 2009公约,评估概率破舱稳性,量化危险区域,采用层次分析法(AHP),以分舱指数、危险区域类型和数量为评估指标,求解各指标对船舶破损安全性的影响权重,并以提高船舶破损后的安全性为目标,评估出最优舱室优化方案。[结果]结果显示,调整危险区域边舱宽度、舱室长度及双层底高度均可提高船舶破舱稳性,以及船舶破损后的安全性。[结论]实验结果表明研究危险区域可提高船舶安全性,在基于多准则评估船舶破舱后的安全性上采用AHP方法可行。

[Objectives]Ship safety is one of the most important performance indicators,and cabin optimization is closely related to improving damaged ship safety.Studying the relationship between damaged ship safety and cabin optimization is a complicated multi-factor problem.[Methods]Based on SOLAS 2009,the probability of damaged stability is evaluated and the danger zones quantified.The analytic hierarchy process(AHP)method is adopted,and the subdivision index,type and quantity of danger zones are taken as the evaluation indexes for calculating the influence weight of each index on damaged ship safety;this is carried out in order to improve the safety of damaged ships and evaluate the optimal cabin optimization scheme.[Results]Adjusting the widths of side cabins,lengths of cabins and double bottom heights of cabins in dangerous areas can improve the stability and safety of damaged ships.[Conclusions]The experimental results show that the study of dangerous areas can improve the safety of damaged ships;moreover,based on multiple criteria,the AHP is feasible for evaluating the safety of ships after sustaining damage to the cabins.
