Abstract:

With the rapid development of city construction, property loss and casualties caused by burning buildings have been increasing fast. As a result, scientific decision-making of emergency resource supply is required to guarantee the safety of a city. The spread trend and suppression function of building fires are portrayed, attaining the fire spread curve. On this basis, a quantitative analysis and calculation of fire-related casualties, property loss and costs of firefighting are given. This may hopefully provide practical solutions to emergency resource supply. A mixed-integer nonlinear planning model is constructed to achieve the minimum of overall loss plus costs of firefighting. This led to an optimal supply scheme of firefighting emergency resources such as extinguishers, fire trucks and firefighters. Finally, in reference to real fire accidents, the feasibility of the model is verified. At the same time, a sensitivity analysis is performed upon such parameters as related to fire response time and fire suppression coefficient. Researches have shown that emergency resource supply scheme of firefighting based upon this paper’s model may effectively improve the utilization efficiency, reduce the time required for fire extinguishing, and reduce property loss and casualties. The scientific reference is provided for analysis upon fire spread mechanisms and emergency resource supply in this study.
