本文选取人员行走速度、客流量、报警时间、出口宽度、闸机开启的延迟时间这五个参数作为研究对象。分析因素本身的不确定性,采用Pathfinder软件模拟人员疏散时间,利用正则化的敏感度指标计算公式计算参数的敏感性指标,从而分析得到地铁人员疏散时间影响因素的不确定性,确定工程实际应用中人员疏散需要量化处理的输入参数。 In this paper, five parameters of walking speed, traffic volume, alarm time, exit width, gate opening delay time are selected as the research object. Analyze the uncertainty of the factors, use Pathfinder software to simulate the evacuation time, and use the regularized sensitivity index calculation formula to calculate the sensitivity index of the parameters, so as to get the uncertainty of the influential factors of subway evacuation time, Personnel evacuation requires quantification of input parameters.
