An experimenter wishes to run a three-component mixture experiment. The constraints in the component proportions are as follows:

 

(a) Set up an experiment to fit a quadratic mixture model. Use n = 14 runs, with four replicates. Use the D-criterion.

(b) Draw the experimental region. 

(c) Set up an experiment to fit a quadratic mixture model with it = 12 runs, assuming that three of these runs are replicates. Use the D-criterion.

(d) Comment on the two designs you have found.
