An Agent-Based Simulation Model for Occupant Evacuation under Fire Conditions

In this paper, an agent-based simulation model is presented to simulate occupant evacuation in fire environment. Based on the agent technology, a computer program is developed to simulate and analyze the egress progress in large public buildings. Through simulation, the occupant behaviors and fire safety performance of different architecture plans can be investigated and analyzed in case of emergency. A CFD (computational fluid dynamics) model is integrated into the model to simulate fire scenarios. By coupling with the fire scenario simulated by CFD technology, the computer simulation program may represent the overall and dynamic process of occupantspsila evacuation under fire expansion, and the mutual relationship between occupantspsila safety and fire hazard. A case study was presented to indicate that the model can be applied to evaluate the fire safety and evacuation efficiency of large public buildings.
