【摘要】：提出人員疏散過程確定性與隨機性的數學描述,建立人員安全疏散時間概率模型。假定某劇院發(fā)生火災,采用拉丁超立方抽樣方法,利用MATLAB編程對疏散過程中的不確定性因素進行計算機抽樣模擬,用概率密度函數描述人員疏散過程中不確定性因素的隨機性,確定人員疏散時間的預期概率分布。概率模型較傳統(tǒng)的確定性人員安全疏散評估方法更適合于人員流動性較大、人員分布不規(guī)律建筑的火災風險評估。
[Abstract]:A mathematical description of the determinacy and randomness of evacuation process is presented, and a probability model of safety evacuation time is established. If a theater fire occurs, the Latin hypercube sampling method is used. The uncertain factors in the evacuation process are simulated by MATLAB programming, and the probability density function is used to describe the randomness of the uncertain factors in the evacuation process. The probabilistic model is more suitable for fire risk assessment of buildings with large mobility and irregular personnel distribution than the traditional deterministic assessment method of safety evacuation.
