Cost model for RFID-based traceability information systems

Radio Frequency Identification (RFID) is a technology that can be used to tag physical objects and to detect and identify them automatically along the supply chain. A RFID-based traceability information system uses the captured data to answer track, trace, and bill-of-materials queries. There are several published system proposals, but it is unclear how solutions for a given supply chain problem can be compared. This paper presents an analytical model to compare traceability information systems based on the estimated cost of data capture and query processing.
