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 Coevolutionary 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.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
