The Simulator
Simulation allows you to discover the distribution of model outputs as a function of the random variation in
the factors and model noise. The simulation facility in the profilers provides a way to set up the random
inputs and run the simulations, producing an output table of simulated values.
An example of this facility’s use would be to find out the defect rate of a process that has been fit, and see if
it is robust with respect to variation in the factors. If specification limits have been set in the responses, they
are carried over into the simulation output, allowing a prospective capability analysis of the simulated model
using new factors settings.
In the Profiler, the Simulator is integrated into the graphical layout. Factor specifications are aligned below
each factor’s profile. A simulation histogram is shown on the right for each response.
