摘要
为了提高船舶火灾环境下人员应急疏散能力,本文基于船舶人员疏散时间计算精确数学模型,采用FLOYD算法与水力模型相结合的方法构建了一种船舶环境下人员疏散路线优化算法。采用FDS数值模拟方法分析火灾衍生物对人员运动能力的影响,发现能见度对人员安全疏散时间要求最高,并将其作为计算火灾环境下的人员疏散优化路线边界条件。以某船上层建筑为例对人员疏散路线进行优化,并采用火灾环境下人员疏散耦合数值分析的方法验证路径优化算法的有效性,结果表明:路径优化算法可降低全局人员疏散时间与伤亡率,提升主要通道利用的均衡性,提升火情下的人员安全。
A method combining the FLOYD algorithm and hydraulic model is employed to construct an optimization algorithm of evacuation routes in the ship environment based on the precise mathematical model for calculating the time of pedestrian evacuation on ships to improve the emergency evacuation capability in the ship fire environment.The FDS numerical simulation method is used to analyze the influence of fire derivatives on the movement ability of passengers.Results showed that visibility has the highest requirement for safe evacuation time and is used as the boundary condition for calculating the optimal evacuation routes under a fire environment.Finally,taking the upper layer building of a ship as an example,the evacuation routes are optimized,and the method for coupled numerical analysis of personnel evacuation under a fire environment is used to verify the effectiveness of the route optimization algorithm.These results indicate that the path optimization algorithm can reduce the overall evacuation time and casualty rate,improve the balance of main channel utilization,and enhance personnel safety under fire.
