TABLES OF MINIMUM-COST, LINEAR TREND-FREE RUN SEQUENCES FOR 2-LEVEL AND 3-LEVEL FRACTIONAL FACTORIAL-DESIGNS

For the two- and three-level fractional factorial designs tabled in National Bureau of Standards Applied Mathematics Series publications 48 and 54, plus the resolution V plans developed by Addelman (Technometrics 7, 1965), we present generator sequences that may be used with the Generalized Foldover Scheme of Coster and Cheng (Ann. Statist. 16, 1988) to produce systematic run orders which minimize, or nearly minimize, a cost function equal to the number of times the factors change levels during the time sequence in which the runs are performed and which simultaneously have all factor main effects components orthogonal to a polynomial time trend.
