In transportation models, the total supply equals the total demand. Some transportation problems may be less restrictive; the total supply may exceed aggregate demand. In such a case, what should it be done for balancing of the model?

- Check the optimality of the basic feasible solution as the simplex method does. If it is not, optimal, then move to the next step. If optimal, stop
- Iterate to the next basic feasible solution by determining the entering and leaving variable using the rate of improvement on the objective value. Return to step 2
- Determine a basic feasible solution to initiate
