摘要：

摘要：  为研究大型舰船的通达性问题，针对大型舰船与客船的不同点，建立了紧急疏散宏观计算模型.以疏散用时最少及水密性最优为目标，在考虑各个集合点容量限制和同向流、逆向流影响的前提下，采用遗传算法，对不同地点出发的功能组进行疏散路径优选.与基于最短路径的方法对比表明，最短路径不一定是舰船疏散的最优路径.

关键词: 通达性, 疏散路径, 水密性, 最短路径

Abstract:

Abstract： To study the accessibility of large ships, a computational model for emergency evacuation was established based on the differences between naval ships and passenger ships. The minimum evacuation time and optimal watertight are two goals of the model. By using genetic algorithms, the evacuation routes for functional groups in different locations were calculated and selected, considering the capacity constraints and influence of encounter flow and counter flow. The comparison with the method based on the shortest path implied that the shortest path is not necessarily the optimal path of ship evacuation.

Key words: accessibility, evacuation path, watertight, shortest path
