Construction of an Online RFID Enabled Supply Chain System Reliability Monitoring Model

Radio Frequency Identification (RFID) application are becoming increasingly popular such as access control, location tracking, industrial automation, and as a replacement for barcodes in consumer products. There are a lot of system components suppliers available, system integrators put the components or subsystems into a complete system, and then how to assess or predict the reliability of integrated RFID system is the major focus in this research. A passive RFID tag tracking system of management is adopted as the experimental platform for this study. The fault tree analysis attempts to model and analyze the failures processes of RFID system, this research highlights the subsystem or components such as electronic tags, readers, middleware, and database server. The component importance analysis also performed to identify weaknesses in RFID system, such as subsystem with higher failure rate which effects system reliability. The database built in this prototype framework will enable the enterprise to monitor and obtain the reliability of RFID system, which also offer valuable reference to the researchers for future work.
