Abstract: The purpose of this paper is to discuss the interpretation of dispersion effects in un-replicated fractional factorials from a robust design perspective. We propose an interpretation of dispersion effects as manifested interactions between control factors and unobserved and uncontrolled factors, an interpretation shown to be useful in achieving robust designs. Further, we show the consequences this interpretation has on the identification of dispersion effects.
