A firm makes a basic scissors consisting of three parts: the left side, the right side, and the screw that holds the sides together. At the present time, the firm has the following numbers of parts on hand and on order. The lead times for reorder of each part are also shown along with a BOM and a sketch of the scissors.
| 0 | On Hand | Weeks of Lead Time | Scheduled Receipts |
| Scissors | 100 | 1 | |
| Left side | 50 | 2 | 100 in week 2 |
| Right side | 75 | 2 | 200 in week 2 |
| Screw | 300 | 1 | 200 in week 1 |
