A truck from the SuperBread bakery drops off several types of loaves of freshly baked bread at the grocery store every other day (we refer to the two-day time interval between the arrivals of the deliveries as the cycle time or review period). For each type of bread from the bakery, there is designated space on the shelves of the store and in the back of the store (the total space allotted to each type of bread depends on the demand for that type of bread). The store has designated space to hold 70 loaves of SuperWheat bread
