摘要 结合某高档餐馆及其类似连锁店的人数统计记录,对比分析直接采用人数统计结果推算设计疏散人数带来的问题。引入Bootstrap模拟技术分析有限统计样本下疏散人数推算的可靠性,分析人员等效密度的置信区间,获得不同置信度下的人员等效密度的取值,给出了相应的人数推算方法和设计建议。 Based on the statistics of population in an upscale res taurant and its chain store,the problems of calculation on the e vacuation number according to the statistics of population were analyzed. The simulation by Bootstrap was carried out to analyze the reliability of calculation on evacuation number based on finite sample. The confidence interval of equivalent density of population was analyzed, and the value of equivalent density of population under different confidence interval was obtained. Suggestions on the calculation method of population and the design of restaurant were put forward.
