Problem maximizing a multicriteria model

Post by caaficus » 1 month ago

Hello.

I'm trying to run a model that maximizes a linear function and the problem it's infeasible. The weird thing it's that if I try to run the same model but minimizing the function, it runs.
Does anybody know why this happen? I'm using CPLEX.

Thanks!

Dide you perhaps confuse dual infeasible with primal infeasible. Dual infeasible often means (if there is a primal feasible point) that the primal is unbounded. -Michael
