The sample data table Piepel.jmp, located in the Design Experiment folder, contains a mixture design with three continuous factors. The design is based on an experiment presented in Snee (1979) and Piepel (1988), where there are boundary constraints on each factor and three additional linear constraints. In the following example, you do the following:
1.
Select Help > Sample Data Library and open Design Experiment/Piepel.jmp.
Figure A.35 Linear Constraints beneath Factors Outline
Select from the inequality menu.
4.
Select Save Constraints from the Mixture Design red triangle menu.
Figure A.36 Constraint Table
Each column contains the coefficients of the factors X1, X2, and X3 in rows 1 through 3. Row 4 contains the value that appeared to the right of the inequality sign.

6.
Click ConstraintState.
Figure A.37 ConstraintState Column Property Panel
The ConstraintState panel for X1 indicates that the direction of the inequality is “greater than” indicating greater than or equal to .
