Hello, I was wondering if anyone else has had this problem. We have a DoE custom design for evaluating factors to optimize for product "B" over an impurity, "C." C isn't independent of B - it's a byproduct which forms only upon B forming, that is A -> B-> C. I see how in Column Info one can set independent limits for responses A and B, but is there a way to set constraints such that B + C < 100%? Thank you!
Not sure I understand completely, but here are my thoughts. Seems you Have A > B + C? In any case, you can add factors as mixture factors and impose linear constraints.
"All models are wrong, some are useful" G.E.P. Box
It sounds like both B and C are responses, rather than being controlled directly. If so, then would their measured values always be less than or equal to 100%? It seems like you might not need to introduce that constraint, and you could just try to maximize B and minimize C.
