Chapter 21 Mixture Designs Overview
Mixture Designs Overview
Mixture experiments are a special class of response surface experiments in which the
product under investigation is made up of ponents or ingredients. Designs
for these experiments are useful because many product design and development
activities in industrial situations involve formulations or mixtures. In these situations, the
response is a function of the proportions of the different ingredients in the mixture. For
example, you may be developing a pancake mix that is made of flour, baking powder,
milk, eggs, and oil. Or, you may be developing an insecticide that blends four chemical
ingredients.
In the simplest mixture experiment, the response (the quality or performance of the
product based on some criterion) depends on the relative proportions of the
components (ingredients). The quantities ponents, measured in weights,
volumes, or some other units, add up to mon total. In contrast, in a factorial
design, the response varies depending on the amount of each factor (input variable).
MINITAB can create designs and analyze data from three types of experiments:
