Data requirements for intralogistics:
Topic: Inventory Tracking
1. Load Identification
What is being moved?
2. Location Identification
Where is it moved from/to?
? ? ? ?
? ? ? ?
OBJECTIVE :
Improve this core supply
chain management process
• 100% accurate
• Zero cost

Bar code scanning for data entry to WMS
• What: pallet label
• Where: location label
Issues:
• Data quality and accuracy
• The human element
• Location verification
• Tied to transactions, not moves
• Pervasive Costs
• Data collection labor costs
• Cost of errors and exception handling
Inventory Tracking:
Current State
ADC is NOT Automatic!

1. Load Identification
What is it?
Several technology options
2. Location Identification
Where is it?
Must be accurate to inches
Solved by Optical RTLS
New State: Automated
Inventory Tracking
GOAL :
• Automate tracking the
“what” and “where”
• A “Smart Truck” Solution
• Drivers don’t do data
collection – no scanning!
Automation Delivers Accuracy
and Cost Reduction

An Optical Real Time Location System
• Digital imaging with image processing
• Mature and proven technology
• Look at ceiling overhead to know location
• Strips of markers in ceiling
• Sensor on vehicle looking up
• Accurate to a few centimeters everywhere
• Works in any building
• Data like GPS
• Precision X,Y
• Bearing or angle
• Speed
Automating Location
Tracking : “Indoor GPS”

1. Optical RTLS tracks truck with inch-accuracy
Calibrated for center of pallet location
2. Fork height sensor
Know height of forks (pallet position)
3. Pallet detector

The Common Issue: Labels
Laser scanning, imaging, and RFID all depend on
labels and a labeling process.
Issues:
• Label placement requirements
• Sensitivity to label quality
• Access limitations to data
• Cost of labels
• No control of labels
New solution: Track By
Location (TBL)
uses the new precision optical
RTLS to track inventory
without dependence on labels
![Page 10: Going Beyond the Label: Advances in Inventory Tracking Methods …cdn.modexshow.com › seminars › assets-2012 › 207.pdf · 2014-03-26 · • Tracking load identities without](https://reader033.vdocuments.us/reader033/viewer/2022060408/5f0fdb3a7e708231d44639be/html5/thumbnails/10.jpg)
• Uses the precision of the optical RTLS position tracking
to track load IDs after a one-time initial bar code scan
• The Logic:
1. Pallet N is put down at location (x,y,z);
2. The next pallet picked from location (x,y,z) must be pallet N
• Every pallet move and exact location is tracked
• Only need to identify the load one time – no scanning
after initial ID read
– Simple, lower cost solution
– No RFID, laser scanner, or optical imager needed
– Eliminates label dependencies
Automated Load ID – Track
By Location

Track By Location Summary
• Tracking load identities without scanning
• Enabled by optical RTLS with inch-accurate tracking
• Requires a “disciplined operation”
• No pallets moved except with TBL vehicles
• No pushing or shoving pallets
• Driver operations are under control
• Great solution for
• Racked storage facilities
• Roll handling operations
• Handling of product difficult to label
• Unusual shapes
• Large variations in shape and size
• Hard to attach a label or keep a label flat
