The Nuts’n’Bolts hardware store stocks some high-value items and a large number of rel- atively low-value components. Inventory is reviewed weekly, and orders are placed with suppliers when inventory levels indicate that current levels are “too low.” Most suppliers deliver the low-value items within two weeks; some of the high-value items may take four weeks for delivery. How would you develop a forecasting system to predict the sales of such items at the individual (SKU ? stock-keeping unit) level? How would you use such fore- casts to plan future purchases? Use PHIVE to go through the necessary steps. For purposes of the discussion, assume that that any historical data you might need can be made available.
