Model choice at experiments with mixtures

VI ABSTRACT Experiments with mixtures, of which the property depends on the proportions of the components of mixture such that the sum of the components equal to one under the condition to fix the total amount of the mixture, is a mixture that has at the least cost price and at the most quality. This study entitled as "Model Choice at Experiments with Mixtures" consists of three chapters. In the first chapter, experiments with mixtures, the aim and the response surface of mixtures were given. In addition, the related papers published in the literature were given briefly. In the second chapter, the designs which are used for the cases either the sum of the proportions of the components present in the blend equals to one or not. In the third chapter, the models for experiments with mixtures were introduced. Finally, a model chosen for a chemical experiment and a fitting blend is found for it in the last chapter. Also the extreme vertices designs applied by using another property taken from the same experiment were given.
