Abstract: [This abstract is based on the author's abstract.] Although not a serious problem in simple additive systems, the confounding of two-factor interactions in fractional factorial experimental design configurations produces clouded information. This prevents the engineer from taking advantage of the nonlinearities of the system that can lead to robust design. Separating the confounded interactions increases cost of investigation. Building on Box's procedure that uses prior information from the first investigation, an approach is developed that expands the concept to permit its application to even more complex patterns.
