Briefly reviewed are the polynomial plus inverse terms mixture models, and the approximately D-optimal measure and D sub n-optimal exact designs for these models in three and four components. The use of Atwoods 1973 improvement to Fedorovs D-optimality algorithm is reviewed and further improvements are suggested. In addition, design region and model symmetry, and a simplified procedure for re-distributing design measure, are used to obtain measure designs in five and six components. Finally, exact designs are obtained from these measure designs.
