Hi,  
So after extending all data input to 2055, on running the model I got Infeasible solution. is this what I am suppose to get?  
I then still went ahead to look at the result, I noticed a lot of irregular patterns, could this be due to insufficient availability of resources to cover the demand within the time period?
