Specialized designs are used to efficiently explore the simplex region: An Introduction to Mixture Designs - AFIT
: Unlike standard factorial experiments where factors are independent, changing one component in a mixture requires a compensatory change in at least one other component to maintain the total. A primer on experiments with mixtures
The defining feature of a mixture experiment is that the sum of the components always equals a constant (usually 100% or 1.0). Specialized designs are used to efficiently explore the

: The response (e.g., taste, tensile strength, or cost) is a function of the proportions .
refers to the foundational concepts and methodologies used to design, conduct, and analyze experiments where the response variable depends on the relative proportions of the ingredients rather than their absolute amounts . This field is widely used in industries like food, pharmaceuticals, and chemicals to optimize product formulations. Core Principles and Characteristics
