So I want to perform an optimization but I want to include constraints of the factor combinations possible, from which the optimum should be found. So I want T1, T2, T3 as well as D1, D2, D3 to be varied at the same time. So all factors containing T should have the same level and all factors containing D should have the same level at the end of the optimization. So in a sense, the respective factors should be tied together for the optimization (T1 = T2 = T3, D1 = D2 = D3). Sadly I did not find how to do this in JMP. Any help is welcome!
