No solution returned

[moatta]

Hello

I have a code that does not return a solution. I'd like to know if there is a contradiction in the equations or something else preventing the solution. How can I investigate this? The code is attached for your reference.

Problem is infeasible and IIS large (from GAMS/BARON):

Code: Select all

Problem is infeasible

 Calculating an IIS
 Irreducibility of the (I)IS provided cannot be guaranteed
 (I)IS contains 125 rows and 52 columns  

So no easy answer. You find many good suggestions how to deal with infeasible models in the forum. Good luck.
