Research on the Suitability of the Emergency Shelter in Tianjin

Emergency shelter is an important part of the urban public safety system, which plays an important role in coping with emergencies. The research on the suitability of the completed emergency shelter is helpful to understand its shortcomings and optimize the city's emergency shelter capability. Based on the three aspects of effectiveness, safety, and accessibility, this paper selected 9 evaluation factors of the suitability of the emergency shelter, used AHP to determine the index weight, and constructed the evaluation index system. On this basis, the paper applied TOPSIS technology to establish an evaluation model for the suitability of emergency shelter in Tianjin and made a comprehensive evaluation of 28 emergency shelters in Tianjin. The results show that there are 11 emergency shelters in excellent level, 15 in a good level, and 2 in the middle level, and 0 in poor level. The research results can provide some references for emergency management departments to evaluate the suitability of urban emergency shelter site selection and optimize its emergency service capacity.
