Zusammenfassung
Response Surface Methodology (RSM) has applications in Chemical, Physical, Meteorological,
Industrial and Biological fields. The estimation of slope response surface occurs frequently in practical
situations for the experimenter. The rates of change of the response surface, like rates of change in the
yield of crop to various fertilizers, to estimate the rates of change in chemical experiments etc. are of
interest. If the fit of second order response is inadequate for the design points, we continue the
experiment so as to fit a third order response surface. Higher order response surface designs are
sometimes needed in Industrial and Meteorological applications. Gardiner et al (1959) introduced third
order rotatable designs for exploring response surface. Anjaneyulu et al (1994-1995) constructed third
order slope rotatable designs using doubly balanced incomplete block designs. Anjaneyulu et al (2001)
introduced third order slope rotatable designs using central composite type design points. Seshu babu et
al (2011) studied modified construction of third order slope rotatable designs using central composite
designs. Seshu babu et al (2014) constructed TOSRD using BIBD. In view of wide applicability of third
order models in RSM and importance of slope rotatability, we introduce A Cubic Slope Rotatable Designs
Using BIBD in four dimensions
