Hello everyone !

I am engineering student in Industrial logistics and I am taking my internship in Simulation with GUROBI. When I run the program for the first time I had "No feasible solution! ". My model has many constrains. Therefore, I won't be capable to fix it because the IIS shows me too many constrains. Besides, I used the lagerproblem.feasRelaxS(1,False,False,True) to look up for feasible solution but nothing pops up.

  Where do these log files come from? From the feasRelax model?

  Yes because the model was infeasible. I added the feasRelaxS in order to make it feasible. 

  I sent you the model by email so you can have a close look into it .

  When I used feasRelaxS(0,False,False,True) I got this .txt file. 

  I'd appreciate your help sir.
