大型公共建筑火灾的Petri网评价方法研究

随着城市化进程不断加快，各类大型公共建筑不但涌现，其火灾造成的人员伤亡和财产损失也日益严重。日前，火灾风险的随机性评价方法虽比较成熟，但难以对其进行定量和动态分析。在综合当前火灾风险评价方法的基础上，针对大型公共建筑的火灾财产损失和人员伤亡的预期风险，提出使用Petri网建模和仿真的方法进行火灾风险评价。将面向对象的Petri网引入到火灾风险评价领域，对风险评价Petri网建模方法、动态监控以及仿真系统设计等方面进行了系统地研究。将该方法应用到某地下商场火灾风险评价中，对评估模型进行验证。

RESEARCH ON FIRE RISK ASSESSMENT OF LARGE PUBLIC BUILDING BASED ON PETRI NET

As the acceleration of urbanization, a lot of large public buildings are welled up. Damage which is caused by fire tends to be more serious. Until now, some fire risk assentment methods have become mature, but difficult to analyze fire risk quantitatively. Based on sununarizing the current fire risk assessment methods, a method based on Petri Nets modeling and simulation is put forward for fire monetary loss assessment and expected fire safety assess- ment of large public building. The paper presents the Object - Oriented Petri Nets into fire risk assessment, studies the risk evaluate model method on Petri net, the dynamic state supervise and control and emulate system design etc . At the same time, the papers apply the method to a market on fire risk evaluation and verify the appraisal model.
