Constraints

Constraints are limitations placed on the model that must be met for a solution to be considered feasible. These include production limitations, logical limitations (the number of products out cannot be more than the number of products in), transportation limitations, inventory limitations, and so on.

If you exclude policies for which there are associated constraints, these constraints will not be applied. For example, assume that you exclude a production policy and you have a production constraint that is used to limit the same Site-Product combination. When the production policy is excluded, the decision variables associated with production are not created. As a result, since there is no production decision variable, the associated production constraint is not created. In cases such as this, the constraint cannot cause an infeasibility.
