Fire Risk Assessment of Living Areas in Old Quarters Based on Combined Empowerment Cloud Modeling:To take the Old Quarter of Hanshuiqiao Street,Qiaokou District,Wuhan City as an Example
In order to improve the accuracy and effectiveness of fire risk assessment of living areas in old quarters,we assessed the fire risk of living areas in old quarters on the basis of the combined empowerment cloud model.Firstly,based on the pressure-state-response(PSR)model,a Fire Risk Assessment Indicator System is established from the three levels,such as fire-causing factor sources,regional vulnerability characteristics and fire rescue prevention ability,and 12 fire indicator factors are selected.Then,subjective and objective assignments are made by the C-OWA-CRITIC method,and the combination empowerment method of game theory is used to determine the weights of the indicators.Finally,the cloud model is used to assess the fire level,and an old quarter of Hanshuiqiao Street,Qiaokou District,Wuhan City is selected for example application.The results show that the fire risk level of sub-regions of1,2,4,6,7,8,9 and 10 are at medium risk,and that of sub-regions of 3,5,11,12,13 and 14 are at low risk,which is in line with the actual situation.It is showing that the model is scientific,applicable,and resolving the subjectivity and uncertainty of the traditional evaluation system.
