Defining Reorder Level in Detail
The reorder level is a crucial aspect of inventory management which specifies the quantity of a particular item that triggers the placement of a new order for its replenishment. This predetermined level ensures that stock is replenished before it runs too low, thereby preventing stockouts and ensuring smooth business operations.
Reorder-Level System
A reorder-level system is a stock control mechanism that relies on the principle that orders for inventory replenishment are placed only when the stock level drops to the reorder level. This system helps in maintaining optimal inventory levels, avoiding both excess stock and stockouts.
Reorder Quantity
The reorder quantity is the specific number of units ordered when the stock level hits the reorder level. This quantity is calculated to ensure that the new stock arrives before the existing stock is completely depleted, maintaining continuous availability of the item.
Examples
-
Retail Store: A clothing store determines that when jeans stock drops to 20 pairs, it is time to reorder. They have set the reorder quantity at 100 pairs to ensure continuous availability and avoid stockouts.
-
Manufacturing Plant: An electronics manufacturer monitors the stock levels of a critical component and sets the reorder level at 500 units. Whenever the stock falls to this level, an order for 2000 units is placed to avoid any disruptions in the production line.
-
Pharmacy: A pharmacy determines that an essential medication reorder level is 50 bottles. When stock reaches this level, an order for 200 bottles is placed ensuring patients have uninterrupted access to the medication.
Frequently Asked Questions
What factors influence the determination of the reorder level?
- Lead Time: The time span between placing the order and its delivery.
- Average Usage Rate: The rate at which stock is used or sold.
- Safety Stock: Buffer stock kept to prevent stockouts due to variability in demand.
How is the reorder quantity determined?
The reorder quantity is typically calculated based on the economic order quantity (EOQ) model, which minimizes total inventory costs (ordering and holding costs), but it can also be set based on practical business requirements such as supplier minimum order quantities.
How does a reorder-level system differ from other inventory management systems?
While a reorder-level system places orders based on reaching a certain stock level, other systems like Just-in-Time (JIT) focus on ordering smaller quantities more frequently to minimize inventory levels, or periodic review systems where inventory is assessed at fixed intervals.
Can the reorder level change over time?
Yes, the reorder level should be periodically reviewed and adjusted based on changes in lead time, demand variability, or overall business strategies.
