During the Persian Gulf War, large amounts of military materiel and supplies had to be shipped daily from supply depots in the United States to bases in the Middle East. The critical factor in the movement of these supplies was speed. The following table shows the number of planeloads of supplies available each day from each of six supply depots and the number of daily loads demanded at each of five bases. (Each planeload is approximately equal in tonnage.) Also included are the transport hours per plane, including loading and fueling, actual flight time, and unloading and refueling. A 36 Supply Depot 1 2 3 4 5 6 Demand 28 D 43 40 29 Military Base C 32 29 41 35 40 43 12 B 40 27 34 42 28 30 6 34 41 25 31 9 E 29 38 31 36 38 40 10 Supply 7 10 8 8 9 6 27 34 38 8 Determine the optimal daily flight schedule that will minimize total transportation time
