The autonomous information system design for item management using rewritable RF-ID tags in supply chain

An autonomous information system design for item management is proposed for an efficient supply chain management. By using rewritable RF-ID tags instead of popular bar codes as a job ID, which represents a manifest of an item, each processing system directly communicates with the tag information of each item, and autonomous item management can be realized. The following four basic functions are designed, to introduce new items, to link each item to processes, to update item information, and acquire process records. The prototype systems, which handles RF-ID tags as processed items, selecting correct items and processes according to a production plan, are confirmed.
