火灾蔓延模型对建筑火灾风险-成本分析中的消防安全工程和保险行业具有重要意义。本文介绍了贝叶斯网络。给出了火灾蔓延模型的有向无环图。在已知着火位置的情况下，可以建立基于贝叶斯网络的火灾从起火点的舱室到另一个舱室的火灾蔓延模型，并利用贝叶斯网络的联合概率分布计算火灾蔓延的概率。给出了未安装喷水装置和安装喷水装置的情况下办公楼的具体应用。(C)2009爱思唯尔有限公司。保留所有权利。
Fire spread modeling is very important to fire safety engineering and to insurance industries involved in fire risk-cost analysis of buildings. In this paper, the Bayesian network is introduced. The directed acyclic graph of a fire spread model is presented. When the fire ignition location is known, the fire spread model based on the Bayesian network from the compartment of fire origin to another compartment can be built, and the probability of fire spread can be calculated by making use of the joint probability distribution of the Bayesian network. A specific application for an office building is presented for a case without sprinkler and one with sprinkler installed. (C) 2009 Elsevier Ltd. All rights reserved.
