[Help-glpk] Simple KPI Functions

Hi all,

I'm looking for two functions that could represent simple KPIs.

In other world, I would like two MILP, in this way:


MAX J = 0.5 * Z1 + 0.5 * Z2

Z1 = -AX + C
Z2 = BX + D



MAX J = 0.32 * Z1 + 0.68 * Z2

Z1 = -AX + C
Z2 = BX + D

Z1 and Z2 are the values of the KPI and they depend on X. The constraints should be equal but the results (the values of Z1 and Z2) should be different changing the coefficients fo the objective function, in this case (0.5 - 0.5) for the MILP1 and (0.32 - 0.68) for the MILP 2.

I can't find a good function. I need just functions where Z1 and Z2 depend on X but changing the coefficients in the objective functions change the values of Z1, Z2 and X.

Thank you for your help
