traditional tracking in manufacturing processes
Traditional tracking in manufacturing processes
  • Processes used today
  • Automotive
  • Aerospace
  • Common methods – human readable / optical
    • Bar coded approach
    • Metal /Plastic I.D.
    • Embedded/engraved numbers
problems with today s tracking techniques
Problems with today’s tracking techniques
  • Lack of automation
  • Manual errors – for human readable
  • Line of site requirement - Optical
  • Total cost is far greater due to human labor cost
  • More time to read numbers
with rfid what are the applications
With RFID – what are the applications?
  • Inventory management – automation
  • Storing and retrieving product feature status for complex products on the product itself
  • Process status /check on a product
  • Entire supply chain
manufacturing inventory
Manufacturing - Inventory
  • Typical inventory questions
    • What is the inventory level in storage?
    • Where is it in the manufacturing floor/warehouse?
    • Locating an individual inventory item
    • Is dynamic inventory scheduling possible based on dynamic customer demand?
  • Technology considerations
    • Tag range
    • Interference with other material
    • How much data is enough?
manufacturing inventory1
Manufacturing - Inventory
  • RFID tags maintain current item information on the tag
      • Useful for managing production of complex or customized products and assemblies
      • Eliminate the need for separate paperwork on assembly status and content
      • R/W requires larger memory tags, e.g., aerospace
manufacturing product process status
Manufacturing – Product/process status
  • Process completion
    • Central product database can be notified when each process has been completed
  • Determine product features
    • Field personnel would use if no user manual
    • Date of manufacture, revision levels, etc.
  • Real-time tracking
    • Inventory, part kits and sub-assemblies
manufacturing benefits
Manufacturing - Benefits
  • Benefits
    • Optimize manufacturing, reduce inventory
    • Find where parts are sitting/waiting
    • Get status of part/assembly
    • Get a finer visibility on what’s happening to in-process inventory (big problem – don’t know exactly where the inventory is when it is in the manufacturing plant)
    • Workflow monitoring
    • Process Planning
    • Automated Inspection
manufacturing challenges
Manufacturing - Challenges
  • Challenges in Manufacturing
    • Where do you put the tag?
    • How do you install it?
    • Does it replace the Part ID?
    • How does it behave in the presence of metal in a factory?
    • Passive/active depends on function
manufacturing industries impacted
Manufacturing industries impacted
  • Any discrete part - component / assembly industry, E.g.
    • Automotive
    • Aerospace
    • Shipbuilding
