Please refer to the Network Diagram below. Let Xij represent the number of units shipped from i to j where i=1,2,3 and j=4,5,6. The objective function is to minimize overall transportation cost while making sure all demand is met. Answer each question independently of the other questions. Unit shipping costs are intentionally hidden from the diagram. Suppose that the original problem has a unique, non-degenerate solution. Part of this solution requires Plant 2 to send 15 units to Retailer 4,10 units to Retailer 5 and 20 units to Retailer 6 . Then, Plant 2's capacity increases by 10 units due to improved productivity. If we solve the new problem, what would happen to the objective function value (the total transportation cost)? The objective function value would increase. The objective function value would not change. None of the others The objective function value would decrease. The problem actually would become infeasible. Please refer to the Network Diagram below.
