基于因子和层次分析法的城市并发火灾危害严重度评估

The Assessment of Hazard Severity of Urban Concurrent Fire Based on Factors Analysis and Analytic Hierarchy Process

城市并发火灾具有并发性、突发性、高危害性等特点。为了控制和防范此类火灾的发生,并发火灾的不同火场火灾危害严重度评估十分必要。使用PASW18.0软件对火灾数据进行因子分析,得到因子综合得分,利用层次分析法确定各影响信息的权重,从而提出火灾危害严重度的计算方法,建立了并发火灾危害严重程度评价体系,得到了危害等级划分标准,为针对此类火灾救援与日常防火监督提供理论依据。

An urban concurrent fire is of the characteristics of being a concurrency, sudden, high hazard. To control and prevent such fires, the assessment of the hazard severity of different urban concurrent fires is crucial. Through the software PASW18.0, this paper carries on factors analysis on the fire data and gets comprehensive score of the factors. With the analytic hierarchy process, the influence information of each factor is confirmed, so that the rele- vant calculation method of the fire hazard can be putted forward. Setting up the system for assessment on the hazard severity of urban concurrent fire and the classification criterion of a hazard grade provides a theoretical basis for such fire rescue and daily fire prevention.
