Abstract

For measuring the goodness of 2m41 designs, Wu and Zhang (1993) proposed the minimum aberration (MA) criterion. MA 2m41 designs have been constructed using the idea of complementary designs when the number of two-level factors, m, exceeds n/2, where n is the total number of runs. In this paper, the structures of MA 2m41 designs are obtained when m>5n/16. Based on these structures, some methods are developed for constructing MA 2m41 designs for 5n/16<m<n/2 as well as for n/2≤m<n. When m≤5n/16, there is no general method for constructing MA 2m41 designs. In this case, we obtain lower bounds for A 30 and A 31, where A 30 and A 31 are the numbers of type 0 and type 1 words with length three respectively. And a method for constructing weak minimum aberration (WMA) 2m41 designs (A 30 and A 31 achieving the lower bounds) is demonstrated. Some MA or WMA 2m41 designs with 32 or 64 runs are tabulated for practical use, which supplement the tables in Wu and Zhang (1993), Zhang and Shao (2001) and Mukerjee and Wu (2001).
