Hello All,
I am rather a newbie with GAMS. My model yields an infeasible solution when solved. I suspect, I have not handled the absolute function in the constraint formulation defined in equation 37-52 (see attached files). Any advise or guidance would be greatly appreciated.

Hi
I'm afraid that some of your equations have been entered wrongly!
for example look at constraint 40!
Am I right?

Many thanks for your corrections. I have fixed it. I still have an infeasible solution. See attached GAMS file. Any advice would be appreciated.

Re: Newbie with GAMS
Hi again,
I think infeasibility comes from the constraints below:
if you comment these two constraints there is no infeasibility.
I do not know exactly but r5 make the objective function badly constrained.

Code: Select all
r5.up = 2.40;
r5.lo =0;
