The resolution of a design is a measure of the degree of confounding in the design. The trade-off in screening designs is between the number of runs and the resolution of the design.
Experiments are classified by resolution number into these groups:
A minimum aberration design is one that minimizes the number of confoundings for a given resolution. A minimum aberration design of a given resolution minimizes the number of words in the defining relation that are of minimum length. For a description of words, see Change Generating Rules. For a discussion of minimum aberration designs, see Fries and Hunter (1984).
