Abstract: For the newly proposed definitive screening designs, we show that, among all possible run orders, the extreme values of level changes depend only on the number of factors, and the corresponding designs can be characterized through some necessary and sufficient conditions. Systematic designs with minimum or maximum level changes are constructed for practical use.
