Simulation sensitivity analysis: A frequency domain approach

A procedure is presented for assessing the sensitivity of a discrete event digital simulation model to the values assumed for its input parameters. A frequency domain approach is taken where the input parameters oscillate throughout a run of the model. Parameter sensitivities are indicated by changes in the frequency spectrum of the simulation response. The spectrum can be used to identify a regression model for the simulated response surface. Several continuous parameters may be screened in a single run.
