Infeasible, but optmal solution found

GAMS

Hi there, for some reason when I run the .gms the optimal solution is found, but the .lst shows that some equations are infeasible… I don’t know why, could anyone help me?

---- masterobj  =E=  objective function

masterobj..  - c(1) - c(2) - c(3) - c(4) - c(5) - c(6) + zmaster =E= 0 ; (LHS = -0.5, INFES = 0.5 ****)

OBS: To run the model the .xlsx has to be in the same directory. I’m brazilian, sorry about my english…

Hi,

You are looking at the equation listing (https://www.gams.com/latest/docs/UG_GAMSOutput.html#UG_GAMSOutput_TheEquationListing) which is part of the model generation output. I.e. the infeasibiities you see refer to the provided start point.

I hope this helps!
