Abstract

Box and Hunter [1] introduced very important concept of rotatability for response surface designs. Measure of rotatability that enable us to assess the degree of rotatability for a given response surface design have been introduced by Park et al. [9]. In this paper, following the method of construction of Park et al. [9], a new measure of rotatability for second order response surface designs using incomplete block designs like pairwise balanced designs (PBD) and symmetrical unequal block arrangements (SUBA) with two unequal block sizes is suggested, which enables us to assess the degree of rotatability for a given response surface design.
