Points to Remember

You can define linear constraints on the variables in mixture experiments.
Because no standard set of designs covers all possible linear constraints, ADX generates -optimal designs by using the vertices and centroids of the constrained region. The optimization tools automatically accommodate the constraints.
ADX can generate, analyze, and optimize mixture experiments (both unconstrained and constrained) with process variables.
ADX generates -optimal designs for mixture experiments with process factors.
ADX automatically includes process variables in the fitted model.
You can set the levels of the process variables in the Prediction Profiler or on the Fixed Levels tab in the Contour Optimizer.
