Schoen, E.D. Goos, P. Publication year 2020 Abstract Row–column designs involve two crossed blocking factors. We propose three combinatorial criteria and a criterion based on D-efficiency to identify optimal row–column arrangements of fractional factorial two-level designs. We search for such arrangements in complete catalogs of 16-run and 24-run orthogonal arrays of strength 2 with two-level treatment factors and two multi-level blocking factors. One of the combinatorial criteria is a good surrogate for the efficiency-based criterion. For searching similar catalogs of strength-3 orthogonal arrays, we adapt the criteria and conduct a complete search for optimal row–column arrangements in catalogs with 64 and 72 runs. © 2019, © 2019 American Society for Quality.
