RFID-Based Asset Management of Time and Temperature Sensitive Materials

Abstract

RFID technology enables tracking of individual assets throughout the supply chain and real-time inventory management. However, the potential benefits cannot be realized until +99 % read rate is achieved. The radio frequency interference, signal fading, and harsh environment often result in not detected items, and subsequently incorrect asset management decisions. This paper presents a novel RFID-based smart freezer with a new inventory management scheme for extremely low temperature environments. The proposed solution utilizes a distributed inventory control (DIC) scheme, systematic selection of antenna configuration, and antenna power control in order to addresses those challenges. The performance of the DIC scheme is guaranteed using a Lyapunov-based analysis and verified in simulations and experiments on industrial freezer test bed operating at-100 °F. The proposed RFID antenna configuration design methodology coupled with locally asymptotically stable distributed power control (LASDPC) ensures a 99 % read rate of items while minimizing the required number of RFID antennas in the confined cold chain environments with non-RF friendly materials.
