Minimum Aberration Blocking Schemes for 128-Run Designs

Several criteria have been proposed for ranking blocked fractional fac- torial designs. For large fractional factorial designs, the most appropriate minimum aberration criterion was one proposed by Cheng and Wu (2002). We justify this asser- tion and propose a novel construction method to overcome the computational challenge encountered in large fractional factorial designs. Tables of minimum aberration blocked designs are presented for N=128 runs and n=8-64 factors.
