Methodology, assumptions and limitations
ROP = average daily demand × lead time + safety stockThe reorder point is a trigger, not an order quantity. Compare inventory position with the ROP.
Assumptions
- Constant average consumption during lead time.
- No scheduled receipts or backorders in the timing estimate.
- In operation, use inventory position: on hand + open orders − backorders.
