Observable Uncontrollable Factors in Parameter Design

Summary: Parameter design does not take into account the common occurrence that some of the uncontrollable factors are observable during production. The extra information any observable uncontrollable factors provides should enhance our choice of values for the controllable factors that both keeps the mean response on target and reduces the variance. This paper describes an approach to explicitly introduce uncontrollable factors into a designed experiment.
