基于信息扩散理论的火灾风险评估模型研究及其应用

Research and Application of Fire Risk Assessment Model Based on Information Diffusion Theory

城市火灾事故不断发生,严重威胁着人们的生命安全。当火灾样本数目较少时,针对传统统计模型难以胜任的特点,引入了信息扩散理论,给出了火灾风险评估的实用模型,并以某市为例进行火灾风险评估。结果表明,该方法简单易行,分析结果意义清楚,具有一定的现实意义,为防火抗灾提供了依据。

The city fire accident occurs unceasingly and it threatens people＇s lives seriously. When the fire samples are few, the tradition statistical model is unfit, so this article introduces the information diffusion theory, gives the fire risk assessment model, and takes some city as the example to conduct fire risk assessment. The result indicates that this method is easy and feasible and the analysed result is dear and has stone certin practical significances, which can provide the basis for the fire protection.
