At the MassMotion User Group Day held at the Institution of Structural Engineers (London, UK) in September 2016, Dr. Michael Kinsey from the Arup Fire Shanghai office presented a talk entitled ‘Evacuation/Pedestrian Modelling: Methods for Determining the Number of Repeat Simulations’. Michael’s presentation was recorded and is available for you to watch below.
The talk initially provides an overview of what are random numbers and broadly how they are generated. The motivations for utilising random numbers are then discussed along with common aspects of evacuation/pedestrian modelling which use such values along with the justification for needing to run repeat simulations in the modelling process. A broad overview of methods for determining the number of repeat simulations is then presented along with some techniques which can be employed to potentially reduce the number of repeat simulation runs.
