基于模糊数学的地铁站安全疏散综合评价模型及应用

Comprehensive assessment model of safety evacuation in subway station based on fuzzy mathematics and its application

阐述了地铁站人员疏散的安全评价在消防中的重要意义,并根据地铁站的特点建立了评估因素集,根据模糊数学原理和层次分析法,建立了地铁站安全疏散评估模型,并结合此模型给出了地铁站安全疏散的评估实例。因素权重采用模糊层次分析法确定,对评估结果采用最大隶属度法进行了处理。模糊综合评估不仅可用于地铁站,亦可用于其他建筑。

The important meaning of safety assessment of evacuation in fire fighting was expatiated.Evaluation factor set was built according to characteristics of subway station.Evaluation model of safe evacuation of subway station was established based on fuzzy mathematical fundamentals and analytic hierarchy process.According to this model,assessment instance of safe evacuation from subway station was given.Factor weights were defined by fuzzy analytic hierarchy process.The result was processed by maximum membership grade.Fuzzy comprehensive assessment can be used not only in subway station,but also in other buildings.
