Interactive Multi Response Surface Optimization under Model Uncertainty for Robust Parameter Design

Industrial Engineering Department, METU

Abstract
We develop interactive approaches for two-response robust parameter design problem considering preferences of a decision maker (DM) under model uncertainty for two cases where variance is homogeneous and heterogeneous. It is desired to minimize the joint variation in the responses and the distances of response means from their target values by deciding on the parameter settings of the product. To provide relevant information on the consequences of solutions to the DM, we produce visual aids on performance measures such as joint response confidence and prediction regions of solutions under consideration. We demonstrate that prediction error of the response surface models affects the quality of the solutions and should be considered in evaluating them.
