A reformed lattice Gas model and its application in the simulation of evacuation in hospital fire

In order to provide the rescuing decision-maker with the optimal evacuation plan when hospital fire happens, so as to improve the rescuing capability, the evacuation process is divided into two sections which include rescue and evacuation. Taking factors of fire to in-patient department into account, combine the swarm behavior in fish school algorithm with Agent-based technology, a reformed lattice gas model is established. Ultimately with the help of simulation software Anylogic, on the basis of reformed lattice gas model the paper simulates the pedestrian evacuation and chase down a plan to solve during rescue. The simulation result indicated that the reformed lattice gas model can simulate the scene of evacuation in hospital fire realistically.
