Abstract
Shopping and entertainment centers represent a great potential danger to the life and health of customers, viewers, as they are unique buildings with a massive presence of people. At any object with a massive stay of people, safe evacuation should be organized before the dangerous factors of a fire reach the maximum permissible values. . The building must have such space planning solutions so that all people in the building can easily get into the safe zone in case of fire before the danger of fire reaches critical values. Fire hazard factors dynamics (OFP) mathematical modeling problem during people evacuation from buildings and structures has not been fully resolved. The OFP dynamics calculation accuracy is largely determined by the source data on the fire load properties reliability. Modern scientific methods for OFP predicting are based on mathematical modeling - on mathematical models of fire. Fire mathematical model describes, in its most general form, the environment condition change in a room over time, as well as a change in the parameters condition of the protecting structures of this room and various elements of the process equipment. The article discusses the types of mathematical models of fire and their use scope. Mathematical models of a fire in a room are conventionally divided into three classes: integral, zone, field (differential). Mathematical modeling allows us to predict the dynamics of fires in buildings for various purposes, and therefore allows us to bring the fire hazard studies of objects to a qualitatively new stage of development and to ensure the transition from comparative to predictable methods, taking into account the operating conditions of the object.
