TY - JOUR PY - 2004// TI - The Effect of Pre-evacuation on Evacuation Times in the Simulex Model JO - Journal of fire protection engineering A1 - Spearpoint, Michael J. SP - 33 EP - 53 VL - 14 IS - 1 N2 - The evacuation time of a building in an emergency can be broken down into a number of constituent times including the pre-evacuation time and the travel time. This paper examines how distributions of pre-evacuation times affect the occupant travel time and hence their effect on the evacuation time in the Simulex model. A simple scenario is assessed mathematically and compared with the results from Simulex with further simulations carried out on a somewhat more complex scenario. Because we expect the pre-evacuation time to be characterized by a distribution of values, simply adding the maximum pre-evacuation time and the movement time over-estimates the evacuation time. Furthermore, when the preevacuation distribution is small the travelling and queuing effects dominate the simulated evacuation time. When the pre-evacuation distribution is large, then travel and queuing effects are not so important and it is the pre-evacuation time that dominates. Finally, the paper examines some aspects of the Simulex model in situations where there is a high occupant density in a space.
