infeasiblity

hi all

i face with error no integer solution for my mip model in gams for vrptw without any try from gams but when i changed time window data to more wide intervel (i changed some data) it starts to trying and running but it result to error no integer solution at last too. in this situation my error is shown because of my model and equations or its because of my data quantity???

regards

Hi n nazari
I hope you find what is going wrong with your model, but your question has nothing to do with GAMS programming.
When GAMS give you this error, it means that there is no integer feasible solution, that’s all. Modify your model.

Best,
