中文摘要：

研究机舱内人员疏散有利于获取最佳逃生路径，保护生命安全。机舱内的空间相对封闭，在突发状况下，疏散的渠道有限，受到突发状况影响很多，无法对意外进行完全的约束建模。传统的疏散模型在小空间疏散路径寻优计算过程中，以固定约束条件描述疏散时的状况，路径选择设定了很多前提条件，应用性较差。提出利用非规则变异算法的机舱内紧急人员疏散模型。计算机舱内紧急人员疏散目标函数，并且针对所有的疏散路径进行编码，获取不同疏散方法的评价标准，并利用上述标准对人员疏散模型进行评价，针对所有的疏散路径进行选择、交叉和变异运算，建立机舱内紧急人员疏散最优模型，得到改进模型的最优解，获取机舱内紧急人员疏散的最优路径。实验结果表明，利用改进算法进行机舱内紧急人员疏散，能够获取最优疏散路径，提高疏散效率。

英文摘要：

A cabin emergency evacuation model is proposed based on the algorithm of irregular variation. Firstly, objective function of emergency evacuation is calculated, and then all the evacuation paths are coded. Afterwards, e- valuation standards of different evacuation methods are obtained and applied to evaluate the evacuation model. Selec- tion, crossover and mutation operations are performed for all the evacuation paths. The optimal model of cabin emer- gency evacuation is set up, with getting the optimal solution of the model, through which the optimal path of emergen- cy evacuation is achieved finally. Experimental results show that the optimal evacuation path can be obtained by this improved algorithm for cabin emergency evacuation, and the efficiency of evacuation can be improved as well.
