Mixture design screening

Statexplorer — Thu, 12 Sep 2024 09:21:33 GMT

I have four factors (A, B, C, D); out of that, I need to use only 3 at a time (either A, C, D or B, C, D at a single run) and the sum of three should be 100.

How can I do that in a single mixture design

Hi @Statexplorer,

The following discussion is very similar to your topic and might help you or the other JMP Users create a Custom mixture design respecting the constraint (even if you already found a solution) :

Also with Classical Mixture designs platform there are other options (when/if applicable) :

Without factors ranges restrictions and linear constraints: choosing a Simplex Centroïd design with K=3 generates a design with up to 3 factors in each experiment :
With factors ranges restrictions and/or linear constraints: choosing an Extreme Vertices design of degree K=3 generates a design with up to 3 factors in each experiment :

Hope this answer may help other users in the Community,
