[Help-glpk] Simple KPI Functions

[Simone Atzeni]

Hi all,

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

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

MILP 1:

MAX J = 0.5 * Z1 + 0.5 * Z2

Z1 = -AX + C
Z2 = BX + D

and

MILP 2:

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
Simone
