This paper presents a conceptually simple and resource efficient method for robust
parameter design. The proposed method varies control factors according to an adaptive one-
factor-at-a-time plan while varying noise factors using a two-level resolution III fractional
factorial array. This method is compared with crossed arrays by analyzing a set of four case
studies to which both approaches were applied. The proposed method improves system
robustness effectively, attaining more than 80% of the potential improvement on average if …

This paper presents a conceptually simple and resource efficient method for robust
parameter design. The method varies control factors according to an adaptive one-factor-at-
a-time plan while varying noise factors using a two-level resolution III fractional factorial
array. The method is assessed and compared against a crossed array method which uses
fractional factorial inner arrays. The comparison is made by looking at the improvements in
robustness across four case studies. The proposed method improves system robustness to …
