Process Improvement through Simplex EVOP Mini Paper Appearing in Summer 1987 Newsletter
Abstract: Simplex EVOP is especially suitable when the process variables can be perturbed only at special times, there are a number of product performance criteria, more than 2 or 3 process variables are to be perturbed, process performance is changing over time, and statistical calculations need be minimized. First the process performance characteristic(s) to be improved are defined. The process variables whose perturbation might lead to performance improvement are identified and their present conditions noted. One identifies small perturbations from these initial conditions and represent them as corners of a simplex. The key idea in this procedure is that you move away from the least favorable condition using the simplex.
