Abstract: We extend the grouping scheme introduced by Wu (1989) and construct a class of saturated asymmetrical orthogonal arrays of the type , where s is a prime power and r is any positive integer. The method is generalized to construct for any prime power s, any positive integer ri, and some combination of m and nj.
Key words and phrases: Asymmetrical orthogonal arrays, fractional factorial designs, method of replacement, grouping scheme.
