An emergency department simulation and a neural network metamodel

R A Kilmer, A E Smith, L J Shuman
Journal of the Society for Health Systems 1997, 5 (3): 63-79
This paper describes a discrete event stochastic simulation of a hospital emergency department, and the development of a metamodel of that simulation. The metamodeling technique used is artificial neural networks, which are trained utilizing the output of the simulation. The performance of the neural network metamodel is compared to the simulation performance for estimating the mean and variance of patient time in the emergency department.
