CEPO-based Research on Evacuation Route for High-rise Building Fire

The decision-making problem of evacuation route in high-rise building fire is actually the dynamic path optimization problem under fire spreading. Since DPO method can not guarantee the actual optimal path, increase unnecessary evacuation route and extend evacuation time under fire, improving ripple spreading algorithm to increase the number of successful evacuation in the safe evacuation time and achieve Co-evolutionary path optimization (CEPO), synchronizing the process of personal evacuation with the process of fire diffusion. Simulate evacuation process of high-rise building by fire dynamics simulator and evaluate the efficiency of DPO method and CEPO method. The result shows that the CEPO method can solve the above DPO problems through an off-line optimization, and greatly improve the efficiency of fire evacuation.
