Mathematical Model of Evacuation Program in a Building

This article researches that how to organize personnel to escape of a building in the shortest time.In order to find out the best evacuation program, this paper establishes a mathematical model of flow of people to evacuate.The model takes the relationship between flow velocity and flow density into account to evacuate the shortest of the objective function.According to this model solution we get a quickly evacuate optimization program of a classroom building.Through the model tests,the authorities make a number of constructive comments.
