The value of information is then quantified to determine whether higher coverage layouts are worth the additional costs associated with the higher number of antennas required. It …

Investigating Present And Future Interactions Between Radio Frequency Identification, Additive Manufacturing And Supply Chain Management, Michael Nobuhiro Ochi

Master's Theses

A screening experiment was paired with research observing the past, present and futures of additive manufacturing (a.k.a. rapid prototyping, 3D printing), radio frequency identification, and supply chain management. The experiment tested different properties of objects created with a desktop fused deposition modelling printer to observe if any single factors or interactions affected the read range of embedded passive UHF RFID inlay. The combination of material and infill percentage had a statistically significant effect on read range, however the analysis is weak since the data could not justify the normality assumption of ANOVA. Furthermore, the size of the effect was small …

Rfid Technology Selection And Economic Justification For Healthcare Asset Tracking, Tyler Robert Peabody, Tali Freed

Master's Theses

Although Radio Frequency Identification (RFID) and Real-Time Location System (RTLS) technologies for inventory tracking have been growing in popularity, the healthcare industry has been reluctant to adopt these technologies. One of the primary reasons for this lack of enthusiasm has been the risk associated with electromagnetic interference between RFID/RTLS systems and medical equipment functionality. The other reason has been the substantial cost and complexity of implementing RFID/RTLS in healthcare organizations. In this study, we show that there are several ways to safely install RFID/RTLS systems to improve the inventory management processes of hospitals and clinics. We then analyze the inventory …

Three-Dimensional Indoor Rfid Localization System, Jiaqing Wu

Department of Industrial and Management Systems Engineering: Dissertations, Theses, and Student Research

Radio Frequency Identification (RFID) is an information exchange technology based on radio waves communication. It is also a possible solution to indoor localization. Due to multipath propagation and anisotropic interference in the indoor environment, theoretical propagation models are generally not sufficient for RFID-based localization. In fact, the radio frequency (RF) signal distribution may not even be monotonic and this makes range-based localization algorithms less accurate. On the other hand, range free localization algorithms, such as k Nearest-Neighbor (kNN), require reference tags to be spread throughout the whole three-dimensional (3D) space which is simply not practical. In this work, a hybrid …
