Problem on Modelling Uncapacitated SAHLP
Posted: Fri Jun 24, 2022 3:15 pm
Hi everyone,
As part of my project I need to model an uncapacitated single allocation hub location problem on GAMS. I don't have a lot of knowledge on GAMS, but I tried to model by myself anyways. On CAB10 dataset, I was able to get a solution (I don't know if the solution is true though). However on CAB25 dataset, I get the error "CPLEX Error 1217: No solution exists. --- Problem is integer infeasible". Can anyone help me what would be the issue with my model? Thanks in advance.
