CWLP Technology Systems 5 — Questions and Answers
Question 1: Which technology uses computer vision and AI to identify products without barcodes or RFID tags in modern fulfillment centers?
- Voice-directed picking
- Machine learning-based image recognition (Correct answer)
- Laser scanning tunnels
- Magnetic stripe readers
Correct answer: Machine learning-based image recognition
AI-powered image recognition systems can identify products, verify picks, and detect defects using cameras without requiring physical labels.
Question 2: In a WMS, 'cross-docking' functionality is characterized by:
- Moving products directly from receiving to outbound staging with minimal or no storage (Correct answer)
- Storing products in a cross-shaped aisle configuration
- Transferring inventory between two warehouse locations
- Docking two trucks simultaneously at the same door
Correct answer: Moving products directly from receiving to outbound staging with minimal or no storage
Cross-docking moves inbound freight directly to outbound shipments, bypassing storage to reduce handling time and inventory holding costs.
Question 3: An Autonomous Mobile Robot (AMR) in a warehouse differs from an Automated Guided Vehicle (AGV) because an AMR:
- Is larger and carries heavier loads
- Navigates dynamically using onboard sensors without fixed tracks or magnets (Correct answer)
- Requires a dedicated IT team to reprogram each shift
- Only operates in temperature-controlled environments
Correct answer: Navigates dynamically using onboard sensors without fixed tracks or magnets
AMRs use SLAM (Simultaneous Localization and Mapping) and onboard intelligence to navigate around obstacles, unlike AGVs that follow fixed paths.
Question 4: What does the 'available-to-promise' (ATP) function in an ERP/WMS calculate?
- The total on-hand inventory across all warehouses
- The quantity that can be committed to a customer order based on current stock and scheduled receipts (Correct answer)
- The reorder point for a given SKU
- The maximum storage capacity of a warehouse location
Correct answer: The quantity that can be committed to a customer order based on current stock and scheduled receipts
ATP considers on-hand inventory, pending receipts, and existing commitments to determine how much can be promised to a new customer order.
Question 5: A warehouse using 'voice-directed picking' (VDP) relies on which core technology?
- Visual displays on smart glasses
- Speech recognition and text-to-speech software integrated with the WMS (Correct answer)
- Haptic feedback gloves that vibrate at the correct location
- RFID readers embedded in picking gloves
Correct answer: Speech recognition and text-to-speech software integrated with the WMS
VDP systems convert WMS pick instructions into spoken commands and interpret verbal confirmations from workers, enabling hands-free, eyes-free picking.
Question 6: In supply chain technology, 'blockchain' is primarily explored for which warehouse/logistics application?
- Replacing WMS software with a decentralized system
- Providing an immutable, shared record of product provenance and chain of custody (Correct answer)
- Encrypting RF communications between scanners and the WMS
- Automating carrier rate negotiation
Correct answer: Providing an immutable, shared record of product provenance and chain of custody
Blockchain's immutable distributed ledger creates a tamper-proof record of each transaction in a product's journey, improving traceability and reducing fraud.
Question 7: What is the purpose of a 'yard management system' (YMS) in a distribution center?
- Managing the landscaping and exterior maintenance schedule
- Tracking and optimizing the movement of trailers and containers in the dock yard (Correct answer)
- Scheduling warehouse associates' breaks and yard time
- Monitoring outdoor temperature for cold chain compliance
Correct answer: Tracking and optimizing the movement of trailers and containers in the dock yard
A YMS provides real-time visibility into trailer locations, dock door assignments, and yard driver tasks to reduce detention charges and improve dock efficiency.
