摘要
The minimum aberration criterion has been advocated for ranking foldovers of 2(k-p) fractional factorial designs (Li and Lin, 2003): however, a minimum aberration design may not maximize the number of clear low-order effects. We propose using foldover plans that sequentially maximize the number of clear low-order effects in the combined (initial plus foldover) design and investigate the extent to which these foldover plans differ from those that are optimal under the minimum aberration criterion. A small catalog is provided to summarize the results. (C) 2009 Elsevier B.V. All rights reserved.
