Mixture Designs

Now in Version 10, DOE++ includes mixture designs, which are used when the factors in an experiment are components in a mixture, and when you wish to determine the best proportions to use for each component. Since the proportions of all the components in a mixture must always sum to one, mixture designs assume that all the component factors are dependent (i.e., changing one component's value in an experiment will necessarily change others).

Mixture designs can also include process variables as factors. For example, if the components in a mixture are different metals that are combined to produce steel, the experimenter can choose to consider process variables like temperature and pressure in order to determine the best way to process the mixture (in addition to estimating the best proportions of the metals).

The following topics include information on specific mixture design types, including:

The ReliaWiki resource portal provides more information about mixture designs at http://www.ReliaWiki.org/index.php/Mixture_Design.

The information presented in these topics is not intended to be an exhaustive discussion of the software. Rather, it offers a summary of each design type along with notes on any special considerations for creation/use of the design and information on the types of analysis information and plots available. It is intended to be used in conjunction with the documentation on design folios.
