Abstract
Kim [1] introduced rotatable central composite designs of second type with two replications of axial points for 2≤v≤8 (v: number of factors). In this paper we have extended the work of Kim [1] for second order rotatable designs of second type using central composite designs for 9≤v≤17.
Keywords: Response surface methodology, central composite designs, rotatability, orthogonality, efficiency.
