Research on Urban Fire Risk Comprehensive Evaluation and Its Applications in China

ABSTRACT

With the urbanization of China, the fire risk in urban areas is increasing. Thus an evaluation of the fire risk is necessary. This article analyzes the main factors influencing the city fire risk in China. The index system of city fire risk evaluation is constructed by various techniques. The mathematical model is established under the comprehensive assessment theory of fuzzy mathematics. The response time of fire departments corresponding to different risk regions is determined on the basis of risk evaluation. In the end the fire station coverage is calculated according to the response time. The evaluation results not only provide basic information for decision-making such as performance-based design of fire stations and city planning of fire protection, but also offer a theoretical foundation for optimizing fire fighting forces in cities.
