Hello everyone after formulating my model in AIMMS, the solver tells me that my solution is not feasible I tried to simplify my model by removing some binary elements but I still get the same answer. I think the problem must be somewhere in the flow conservation or capacity constraint, could someone take a look at it and tell me the problem.
I also have a duplicate column warning message I think it's from my bad formulation of the problem if someone can also tell me how to fix it thank you very much.
Ps: I saw that these questions were asked regularly but I took the liberty of making a new topic because I would like to have an answer specific to my case and I could not solve my problem by reading the other topic.
