CWLP Layout Design 2 — Questions and Answers
Question 1: Which layout principle minimizes the distance traveled by material handlers in a warehouse?
- Maximizing vertical storage height
- Placing fast-moving SKUs near the shipping dock (Correct answer)
- Grouping all bulk storage in the center
- Separating receiving and shipping to opposite ends
Correct answer: Placing fast-moving SKUs near the shipping dock
Locating high-velocity items close to the shipping dock reduces travel distance and improves throughput.
Question 2: What is the primary purpose of a cross-dock layout in a warehouse?
- Long-term bulk storage of seasonal inventory
- Direct transfer of goods from inbound to outbound without putaway (Correct answer)
- Storing hazardous materials safely
- Organizing pick-to-light systems
Correct answer: Direct transfer of goods from inbound to outbound without putaway
Cross-docking moves product directly from receiving to shipping, eliminating storage time and reducing handling.
Question 3: In a U-shaped warehouse flow layout, where are both receiving and shipping docks typically located?
- On opposite sides of the building
- On the same wall (Correct answer)
- At the building corners
- Along the longest wall only
Correct answer: On the same wall
A U-flow layout places receiving and shipping on the same wall, allowing shared dock resources and equipment.
Question 4: What does 'slotting' refer to in warehouse layout design?
- Assigning dock door numbers to carriers
- Optimally assigning products to storage locations based on velocity and size (Correct answer)
- Installing conveyor slots between pick zones
- Scheduling shift changeovers
Correct answer: Optimally assigning products to storage locations based on velocity and size
Slotting is the process of assigning each SKU to the most efficient storage location based on pick frequency, weight, and cube.
Question 5: Which aisle configuration is best suited for operations requiring simultaneous two-way forklift traffic?
- Narrow aisles (less than 8 ft)
- Very narrow aisles (VNA) under 6 ft
- Wide aisles (12 ft or more) (Correct answer)
- Zero-aisle automated systems
Correct answer: Wide aisles (12 ft or more)
Wide aisles of 12 feet or more allow two forklifts to pass each other safely, supporting simultaneous two-way traffic.
Question 6: What is a 'golden zone' in the context of warehouse shelving and rack design?
- The most profitable storage area near the office
- The storage height range between knee and shoulder level that minimizes ergonomic strain (Correct answer)
- The highest rack level used for overflow
- A designated area for gold-rated suppliers
Correct answer: The storage height range between knee and shoulder level that minimizes ergonomic strain
The golden zone (approximately knee to shoulder height) is where pickers can retrieve items most easily without bending or reaching overhead.
Question 7: A warehouse designer increases column spacing to accommodate wider rack bays. What is the primary trade-off?
- Reduced building height clearance
- Higher structural steel costs (Correct answer)
- Lower storage density per square foot
- Increased fire suppression requirements only
Correct answer: Higher structural steel costs
Wider column spacing requires heavier structural members, significantly increasing the cost of the building's steel framework.
