If one of the components in a mixture design must have a fixed proportion, what's the best way of handling it?

As far as I can see Minitab only accepts upper and lower bounds, and the upper must be higher than (not equal to) the lower. I can probably rig it by making the difference very small, but is there a better way?

Alternatively I could convert the rest of the components to pseudo components.

Any thoughts?

Thanks, Glen
