Question

True or False In a transportation problem, items are allocated from sources to destinations at a minimum cost. 1. 2. In a transportation problem, items are allocated from sources to destinations at a maximum value 3. The linear programming model for a transportation problem has constraints for supply at each source and demand at each destination. 4. In a balanced transportation model where supply equals demand, all constraints are equalities. 5. In an unbalanced transportation model all constraints are equalities. 6. In order to model a "prohibited route" in a transportation or transshipment problem, the route should be omitted from the linear program. 7. In an unbalanced transportation problem, if demand exceeds supply, the optimal solution will be infeasible. 8. The transshipment model includes intermediate points between the sources and destinations. 9. In a transshipment problem, items may be transported from sources through transshipment points on to destinations 10. In a transshipment problem, items may be transported from one source to another. 11. In a transshipment problem, items may be transported from one transshipment point to another. 12. In a transshipment problem, items may be transported from one destination to another 13. In a transshipment problem, items may be transported directly from sources to destinations.
