Abstract: Prescott (2000) has used augmented pair designs for the projection of response surface designs onto the mixture space and obtained orthogonally blocked designs. Singh (2003) used the Darroch and Waller quadratic model to construct orthogonal designs in two blocks for three and four components. In this paper, we have used quantitative screening designs based on weighing matrices to obtain mixture designs by the method of projection. These mixture designs have been further compared on the basis of uniformity and optimality criteria. Orthogonal blocking of the projected mixture designs has also been presented.
