Help regarding 'Problem infeasibility'

Post by Indrajith R S » 1 year ago

Hi all,
I am a beginner in gams modelling and I'm doing a milp program to design a risk reduced and Sustainable supply chain model with reduced cost.
I developed the model and tried to solve it by coding in gams.Hypothetical values were initially put for various factors like cost,index etc. But during solving i got the message that the problem was infeasible/unbounded and have no solutions.
Im quite confused about what to do.

My model and program code have been attached herewith. Corrections and suggestions regarding what's wrong would be a great help for me.
