Infeasible model with fixed feasible solution

Hi, I am having trouble with my model, as it appears to be integer infeasible (CPLEX error 1217), even when I fix the binary variable x(i,j,m) for specific links to 1, establishing a feasible solution. This model is a MILP formulation of a time dependent VRP, where the goal is to minimize the total ...

Re: Error 66 - equation symbol has no values assigned

Hi Michael, Thank you very much for the answer, I can't believe I missed that! I guess it's because GAMS didn't complain, as you mentioned. I have ran the model again, and that problem is solved. However, now when I run itl it says that equation 2 is infeasible, and terminates the execution: **** Ex...

Error 66 - equation symbol has no values assigned

Hello, I am having problems with my model. I've got two errors: the error 66 in the solve statement and the error 256 in the display statement (I know error 256 is consequential). On the listing file I get the following: **** The following MIP errors were detected in model tdvrp: **** 66 equation Eq...
