TRUE/FALSE:
Problem 1: In a transportation problem, items are allocated from sources to destinations at a maximum cost.
Problem 2. The linear programming model for a transportation problem has constraints for supply at each source and demand at each destination.
Problem 3: In a balanced transportation model where supply equals demand, all constraints are equalities.
Problem 4: The transshipment model is an extension of the transportation model in which intermediate transshipment points are added between the sources and destinations.
Problem 5: In a transshipment problem, items may be transported from one transshipment point to another.
Problem 6: An assignment problem is a special form of transportation problem where all supply and demand values equal 0.
