摘要
通过对火灾导致电梯疏散失败的故障树的建立与分析,计算了导致顶事件发生的最小割集与最小径集,以及影响顶事件发生的结构重要度和割集重要度。并由此提出了火灾情况下降低电梯运行风险,提高可靠性的相关措施。为火灾情况下利用电梯进行疏散的可靠性提供了参考依据。
In this paper we establish and analyze the failure tree of elevator evacuation stopping caused by fire and calculate the minimal cut set, minimum path sets, structure important degree, cut-set important de- gree in the failure tree that affect the occurrence of the top event. We propose measures to reduce the risk of top events and provide the reference for the study of the reliability of elevator evacuation under fire condi- tions.
