## Custom DOE Factor Constraints for Col Sum

Hi,

I am designing an experiment where the physical availability of some inputs is limited.  Is is possible to use Factor Constraints to account for this?

For example, in the DOE below, is it possible to add a Factor Constraint such that

Sum(X1 == -1) <= 2

or

Col Sum(X1 == -1) <=2

I am using JMP12.  Thanks!

DOE(

Custom Design,

{Add Response( Maximize, "Y", ., ., . ), Add Factor( Continuous, -1, 1, "X1", 0 ),

Add Factor( Continuous, -1, 1, "X2", 0 ), Add Factor( Categorical, {"L1", "L2", "L3"}, "X3", 0 ),

Set Random Seed( 1377382337 ), Number of Starts( 194435 ), Add Term( {1, 0} ), Add Term( {1, 1} ),

Add Term( {2, 1} ), Add Term( {3, 1} ), Add Alias Term( {1, 1}, {2, 1} ), Add Alias Term( {1, 1}, {3, 1} ),

Add Alias Term( {2, 1}, {3, 1} ), Set Sample Size( 6 )}

)

## Re: Custom DOE Factor Constraints for Col Sum

Here is a slightly more user-friendly script, with Number of Starts( 10 )...

DOE(
Custom Design,
{Add Response( Maximize, "Y", ., ., . ), Add Factor( Continuous, -1, 1, "X1", 0 ),
Add Factor( Continuous, -1, 1, "X2", 0 ), Add Factor( Categorical, {"L1", "L2", "L3"}, "X3", 0 ),
Set Random Seed( 1377382337 ), Number of Starts( 10 ), Add Term( {1, 0} ), Add Term( {1, 1} ),
Add Term( {2, 1} ), Add Term( {3, 1} ), Add Alias Term( {1, 1}, {2, 1} ), Add Alias Term( {1, 1}, {3, 1} ),
Add Alias Term( {2, 1}, {3, 1} ), Set Sample Size( 6 )}
