Optimization of process parameters using weighted convex loss functions

Setting the optimal process parameters under certain criterion is among the most important factor to determine a product's profit. In this study, we generalize Taguchi quality model to more general process scenario, which consider multiple input and output quality variables simultaneously. Using the weighted convex loss function, we discuss the optimization of process parameters for Taguchi quality model and a trade-off problem as well. The working requirements for optimization are presented and the examples to illustrate our result are demonstrated.
