A traffic manager has two options in scheduling a truck to make multiple pickups and deliveries. The pickup-delivery problem is shown pictorially in Figure 6-11. The traffic manager can ship the accumulated volumes as single shipments between the designated points or can use the stop-off privilege at $25 per stop for any or all portions of the trip. If the traffic manager wishes to minimize shipping costs, which alternative should be chosen? Assume that the final destination point incurs the stop-off charge.
