CIM Warehouse Operations & Storage Systems 2 — Questions and Answers
Question 1: Which storage system uses horizontal carousels to bring items to the picker, reducing travel time?
- Vertical lift module
- Horizontal carousel system (Correct answer)
- Push-back rack
- Drive-in rack
Correct answer: Horizontal carousel system
Horizontal carousel systems rotate bins on an oval track to bring products to a stationary picker, minimizing walking time.
Question 2: What is the primary purpose of a receiving dock leveler in warehouse operations?
- To weigh incoming shipments automatically
- To bridge the height gap between the dock and truck bed (Correct answer)
- To sort packages by destination
- To scan barcodes on arriving pallets
Correct answer: To bridge the height gap between the dock and truck bed
A dock leveler bridges the height difference between the loading dock floor and varying truck bed heights, enabling safe forklift access.
Question 3: In a cross-docking operation, how long are goods typically held in the facility?
- 1–3 weeks
- 3–7 days
- Less than 24 hours (Correct answer)
- Up to 30 days
Correct answer: Less than 24 hours
Cross-docking transfers inbound shipments directly to outbound transport with minimal storage, typically within 24 hours or less.
Question 4: Which warehouse layout strategy places fast-moving (A-class) items closest to the shipping area?
- ABC slotting (Correct answer)
- Random slotting
- Alphabetical slotting
- LIFO slotting
Correct answer: ABC slotting
ABC slotting positions high-velocity A items near the shipping dock to minimize picker travel distance and increase throughput.
Question 5: What does the term 'golden zone' refer to in warehouse ergonomics?
- The most profitable storage area
- The shelf height range between knee and shoulder level (Correct answer)
- The area near the receiving dock
- The aisle reserved for high-value items
Correct answer: The shelf height range between knee and shoulder level
The golden zone is the ergonomic picking range between knee and shoulder height where bending and reaching are minimized, reducing injury risk.
Question 6: A warehouse uses a narrow-aisle configuration with turret trucks. What is the main trade-off compared to standard aisles?
- Higher throughput but lower storage density
- Lower storage density but faster picking
- Higher storage density but reduced equipment flexibility (Correct answer)
- Lower equipment cost but higher labor cost
Correct answer: Higher storage density but reduced equipment flexibility
Narrow aisles increase storage density by reducing aisle width, but require specialized guided vehicles that cannot operate in standard aisles.
Question 7: Which metric measures the percentage of available warehouse storage capacity currently in use?
- Throughput ratio
- Cube utilization rate (Correct answer)
- Inventory turn rate
- Fill rate
Correct answer: Cube utilization rate
Cube utilization rate measures the percentage of the warehouse's total cubic storage volume that is currently occupied by inventory.
