The book dwells mainly on the optimality aspects of mixture-of-mixture experiments. In this book, mixture experiments with optimality have become the focus of much attention because of their wide range of applicability and the ease with which these can treat complicated problems. The techniques are ideally suited to express response variables as a function of the proportions of the mixture components within the limiting cost. The use of mixture experiments for production has not been fully explored. Therefore, an attempt is being initiated to assess the utility of mixture experiments for output in detail. Usage of optimal mixture experiments is quite helpful in practical production.
