A combined model of the development of events in case of fire

In modern conditions, evacuation is one of the main ways to ensure the safety of people in the event of an emergency, in particular, in case of fire. The task of determining the level of fire risk in buildings includes many factors that affect the outcome of the evacuation. This leads to the need to simulate evacuation using information technology. The article describes a combined model of the development of events during a fire, including modeling both the spread of a fire in a building and its dangerous factors, as well as the behavior of people during evacuation in an emergency. Using the Unity 3D engine, a software product has been developed that allows you to visualize the course of events during a fire, taking into account these factors. Simulation of fire and agent behavior is performed using Microsoft Visual Studio 2017 in C#. The use of Unity component structure allowed to bind the scripts to the corresponding types of objects (agent, fire source, evacuation area) and reproduce the described patterns of their behavior. The behavior of agents is modeled taking into account the level of emotional state of the agent, his field of vision, his level of awareness of the structure of the building, volitional and leadership qualities. To test the performance of the model, the premises of the building were recreated. A number of experiments have been performed. On the basis of the developed model, it is possible to obtain, without using large computing power, the most complete picture of the evacuation course during a fire, to evaluate the level of fire risk taking into account both objective and psychological factors.
