A Catalog of Orthogonally Blocked 3-Level Second-Order Designs with Run Sizes $\le 100$
by
Nam-Ky Nguyen and Aloke Dey
Box-Behnken designs (Box and Behnken, 1958, 1960) form a very popular class of 3-level second-order designs when the number of factors is small, typically, seven or less. For larger number of factors these designs are not so popular because then, these designs require a large number of runs. This paper provides a catalog of 3-level second-order designs for 5-11 factors with run sizes $\le 100$. All the designs reported can be orthogonally blocked and are seen to have high $D$-efficiencies.
