基于WSR-可拓云理论的地铁车站火灾安全评价

Fire Safety Evaluation of Subway Station Based on WSR-Extension Cloud Theory

为解决地铁车站火灾安全评价中指标量化的模糊问题和边界的不确定性问题,将物元可拓理论和云模型理论结合,提出基于可拓云理论的地铁车站火灾安全评价模型。基于“物理-事理-人理”(WSR)理论,从管理因素、设备因素、设计因素和人员因素4个维度出发,构建地铁车站火灾安全评价指标体系;基于博弈论修正G1法及熵权法算得的指标权重,得到各指标的组合权重;利用可拓云理论,最终确定地铁车站的火灾安全等级。以沈阳地铁十号线淮河街沈医二院车站为例进行评价,结果表明:该车站火灾安全等级为Ⅰ级,安全状态为安全,并为地铁车站未来的消防管理工作提出了有针对性的建议。

In order to solve the fuzzy problem of quantitative index and the uncertain problem of boundary in the fire safety evaluation of subway station,the matter-element extension theory and cloud model theory are combined to propose a fire safety evaluation model of subway station based on the extension cloud theory.Based on the theory of physics-reasoning-human reason(WSR),and starting from the four dimensions of management factor,equipment factor design factor and personnel factor,the index system of fire safety evaluation in subway stations is constructed.Based on game theory,the index weights calculated by G1 method and entropy weight method are modified to obtain the combined weights of each index.The extension cloud theory is used to determine the fire safety level of subway station.Taking Shenyang Metro Line 10,Huaihe Street,Shenyi Second Hospital Station as an example,the evaluation is conducted.The results show that the fire safety level of the station is level I and the safety status is safety,and some suggestions are put forward for the fire management of the subway station in the future.
