Simulation and Optimization of Emergency Evacuation of Huoshenshan Hospital Based on BIM and Pathfinder

After the outbreak of the Covid-19 epidemic, Huoshenshan Hospital, as the main place for patient isolation, is characterized by large floor space and high staff density, and its evacuation time is directly related to the safety of patients and medical care. In this article, we use BIM and Pathfinder software to establish an emergency evacuation simulation model, setting 2400 patients of different ages and degrees to participate in the simulation, and carry out the simulation in Steering behavior mode to study the influence of evacuation mode, exit size and initial distribution of personnel on the evacuation time and evacuation distance of Huoshenshan Hospital respectively. The simulation results provide a theoretical basis for the standardized management of Huoshenshan Hospital and have certain reference significance.
