人员疏散过程潜伏着巨大的安全隐患,合理出口设计是减免伤亡的有效方法。本文运用排队论知识,建立出口服务模型,结合算例分析,在相同情况下,单排队方式较优越,采用单排队方式对不同出口数目的情况进行模拟,将不同出口数目等效表示成单个出口的宽度,从而得出宽度与疏散指标的关系,再结合多排队方式,经多次模拟得到不同出口数目情况下的出口宽度与疏散时间的关系,综合疏散人员总数与安全疏散时间等制约因素,选出符合要求的出口方案。本文有助于人员疏散模型的完善,并对实际的出口方案设计提供了一个导向。
Personnel evacuation process lurks a huge security risk, reasonable export design is an effective way to reduce casualties. In this paper, the knowledge of queuing theory is used to establish the export service model. In combination with the example analysis, in the same situation, the single queuing method is superior. The single queuing method is used to simulate the different export numbers. The different export numbers are equivalently expressed as a single export The relationship between width and evacuation index is obtained. Combined with multi-queuing method, the relationship between exit width and evacuation time under different exit numbers is obtained through multiple simulations. Based on the constraints such as the total number of evacuees and the evacuation time, Select the export plan to meet the requirements. This article helps to perfect the evacuation model of personnel and provides a guide to the actual design of export programs.
