What term describes a difference between the inventory recorded in the system and the actual on-hand quantity?
Lead time variance
Stock turnover
Inventory discrepancy
Reorder point
An inventory discrepancy is the mismatch between recorded and actual stock quantities. It highlights errors in counting, recording, or theft. Identifying discrepancies is the first step to reconciling inventory.
Which method involves counting a subset of inventory at regular intervals rather than the entire stock?
ABC analysis
Annual physical inventory
Just-in-time replenishment
Cycle counting
Cycle counting schedules partial counts of inventory items on a rotating basis. It maintains accuracy continuously without shutting down operations. This contrasts with full annual physical inventories.
Which technology uses radio waves to automatically identify and track inventory items?
QR code labeling
Optical character recognition
RFID
Barcode scanning
RFID (Radio Frequency Identification) uses radio waves to read tags without line-of-sight. It automates tracking through gates and handheld readers. This improves both speed and accuracy.
What is the primary purpose of safety stock in inventory management?
Reduce holding costs
Increase order quantity
Buffer against demand variability
Shorten lead time
Safety stock serves as a cushion to protect against fluctuations in demand or supply delays. It reduces the risk of stockouts. Holding costs may increase, but service levels improve.
ABC classification divides inventory items based on what criterion?
Physical dimensions
Annual consumption value
Number of suppliers
Supplier lead time
ABC classification ranks items by their annual consumption value (unit cost � - annual usage). 'A' items are highest value, 'B' moderate, 'C' lowest. This guides resource allocation for counting and control.
In a perpetual inventory system, what technology is most commonly used to update stock levels in real time at the point of transaction?
Periodic physical count
Barcode scanning
Time-phased order point
Manual data entry
Barcode scanning captures item data instantly at sales or receipt and updates the system in real time. Manual entry and periodic counts are slower and less accurate. This supports precise inventory control.
A category A item under ABC classification accounts for 70% of inventory value but only 10% of items. How often should it typically be cycle counted?
Weekly
Quarterly
Annually
Monthly
High-value 'A' items justify more frequent counts to ensure accuracy, often weekly. 'B' items may be monthly and 'C' items quarterly or annually. This frequency reduces high-cost errors.
Which metric directly measures the accuracy of inventory records?
Stockout rate
Inventory accuracy rate
Fill rate
Inventory turnover
Inventory accuracy rate compares recorded quantities to actual counts, indicating record reliability. Fill rate measures service level, turnover measures efficiency, and stockout rate shows shortage frequency.
When calculating safety stock using service level, lead time, and demand variability, which factor represents the desired probability of not hitting a stockout?
Service level factor (Z-score)
Average demand
Order quantity
Lead time demand
The service level factor is the Z-score associated with the desired fill rate and determines how many standard deviations of safety stock are held. Other terms do not represent probability directly.
A warehouse wants to minimize manual errors by automatically updating inventory as items move. Which technology provides automated updates without line-of-sight scanning?
RFID
Manual cycle count
Barcode scanning
QR code labels
RFID tags can be read remotely through antennas and gates, capturing movement data automatically. Barcodes require direct scanning. Manual counts interrupt operations.
A retailer experiences frequent stockouts due to forecast errors. Which approach can improve demand forecasts using historical trends and seasonality?
Basic moving average
Just-in-time replenishment
Economic Order Quantity (EOQ)
Exponential smoothing with seasonality adjustment
Exponential smoothing with a seasonal component adapts to changing trends and patterns, improving forecast accuracy. JIT and EOQ address ordering, not forecasting sophistication.
If the lead time for a key component doubles but demand variability remains constant, what happens to the required safety stock?
It doubles
It increases by a factor of √2
It decreases
It remains the same
Safety stock is proportional to the standard deviation of demand during lead time, which scales with the square root of lead time. Doubling lead time increases safety stock by √2, not twofold.
What is a key advantage of cycle counting compared to an annual physical inventory?
Requires full warehouse closure
Continuous accuracy without shutdowns
Higher disruption to operations
Lower count frequency
Cycle counting spreads counts across the year and avoids full shutdowns. It provides ongoing accuracy checks. Annual counts require complete shutdowns and are more disruptive.
For products with highly intermittent demand, which safety stock policy is most appropriate?
Safety stock based on average lead time
Dynamic safety stock based on demand variability
Min - max without safety stock
Fixed safety stock level
Intermittent demand requires safety stock that adjusts to changing variability rather than a fixed level. Dynamic policies recalculate stock based on recent demand patterns.
Which warehouse technology provides precise item location tracking and reduces time spent searching for missing stock?
RFID with real-time location systems
Periodic manual slot checks
Paper-based location logs
Batch barcode scanning
RFID paired with real-time location systems (RTLS) pinpoints item positions continuously. Manual logs and periodic checks are slower and prone to human error.
Given a 95% service level (Z = 1.65), a lead time of 10 days, and a daily demand standard deviation of 20 units, what is the approximate safety stock?
330 units
165 units
104 units
63 units
Safety stock = Z � - σ_demand � - √lead_time = 1.65 � - 20 � - √10 ≈ 1.65 � - 20 � - 3.16 ≈ 104 units. This formula accounts for variability over lead time.
A B-category item shows a 3% cycle count error rate despite monthly counts. What is the most appropriate corrective action?
Reclassify the item as A and count weekly
Merge it with C-category counts
Remove it from the cycle counting program
Decrease its count frequency to annually
High error rates on B items warrant more frequent counts, so reclassifying to A ensures weekly checks. Reducing frequency or removal would worsen accuracy.
A warehouse consistently finds inventory discrepancies at the shipping dock. Which intervention most directly addresses this root cause?
Increase overall safety stock levels
Implement a push replenishment system
Install RFID-enabled dock door readers
Switch to annual physical inventories
RFID docks capture item movements in real time as goods exit, preventing unrecorded shipments. Safety stock and annual counts don't fix location-specific errors.
A product shows both upward trend and seasonal peaks. Which forecasting method best handles these patterns for inventory planning?
Holt-Winters seasonal exponential smoothing
Basic exponential smoothing
Simple moving average
Linear regression without seasonality
Holt-Winters smoothing includes components for level, trend, and seasonality, making it ideal for series with multiple patterns. Basic methods miss seasonal or trend effects.
If a company's cost of goods sold is $500,000 and its average inventory is $100,000, what is its inventory turnover ratio?
50
0.2
5
1.5
Inventory turnover = COGS / average inventory = $500,000 / $100,000 = 5. This ratio indicates the number of times inventory is sold and replaced.
