Comparison of experimental designs combining process and mixture variables: Part I. Design construction and theoretical evaluation

The combination of process variables and mixture variables in experimental design is a problem which has not yet been solved. It is examined here whether a set of designs can be found which can be used for a series of models of reasonable complexity. The proposed designs are compared with known designs. A two process by three mixture variables case is used for examination of the designs. It is found that suitable designs do exist, and that the design depends on the system under research.
