摘　　要：在工程实际中,通过人员安全疏散所需要的时间与人员安全疏散可用的时间进行比较来判断建筑的疏散设施能否满足突发情况下人员安全疏散的要求。将建筑的疏散设施抽象成网络的节点,从而将人员在建筑中的疏散流程简化成节点的串联系统模型,并联系统模型或者是串、并联系统组成的复杂模型,并给出了计算的方法。In practice, if available safety egress time is longer than required safety egress time, people can evacuate the building in urgency successfully. In this paper, the evacuation facilities such as doors were abstracted as units of the net, and the evacuation course was simplified as series-wound net, shunt-wound net or their built-up system. The expressions of the algorithms for the four different systems were presented.

关 键 词：人员疏散 疏散设施 串联模型 并联模型
