Software Package for Modeling the Process of Fire Spread and People Evacuation in Premises
2019
The article proposes a software package containing effective implementation of models of the dangerous fire factors spread dynamics and people evacuation in premises. The dangerous fire factors spread model included in the package consist of fire and heat spread models. The first one is based on two-dimensional four-state probabilistic cellular automaton, the second one is based on simple graph theory apparatus and basics of thermodynamics. The people evacuation model implemented in the package is based on multi-agent systems approach, simple graph theory and basics of mechanics which include kinematics, conservation laws and collision theory. The package implementation process in the Java programming language is described, advantages of the chosen language are listed. The software package distinctive features and functional requirements are listed and explained, its inner module structure is described and illustrated, user interaction types are shown. The package allows to simulate and analyze critical situations that arise during a fire, calculate the dynamics of dangerous fire factors development and simulate people evacuation from the premises. The implemented models and the algorithm for their interconnection provide high model performance and accuracy [1].
