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 …

Economic Impact On Annual Profit Of A Retail Inventory Management System When Using Rfid And Considering Discrepancy Ratio, Inaccuracy Ratio, Backorders, And Federal Income Tax, Liyuan Zhang

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

Radio Frequency Identification (RFID) emerged as an important technology with the ability to improve the efficiency and accuracy of object tracking. It has brought cost savings and added value to a wide variety of fields. Retail inventory management system is one of the beneficial fields. In order to better satisfy customers and to improve profit, retailers demand high accuracy in inventory management to service customers without redundant on-hand inventories. The RFID technology, which provides more accurate tracking, can improve retailers’ profit.

Two accuracy factors were proposed to determine the difference in the profit of a retailer inventory management system caused …

Economic Analysis Of Continuous Monitoring Of Commercial Truck Tire Pressure Using Tire Pressure Monitoring Systems (Tpms) And Rfid Technologies., Afolabi A. Ogunwemimo

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

The trucking industry is a major contributor to the US economy. By providing the essential services of transportation and distribution needed in today’s dynamic industry, the transportation industry has evolved into an integral player in various supply chains. The trucking industry is the largest transportation provider for other industries and employs 10.1 million workers in the United States (ATA, 2003).

This research is an analysis of the economic impact of maintaining proper air pressure in the tires of commercial trucks. Various studies have been carried out on understanding the relationship between tire pressure and fuel consumption (National Research Council, 2006). …

Innovating Continuous Review Policies With Rfid, Angela Garza

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

Inventory accuracy is critical for NASA astronauts in space. In 2004, astronauts onboard the International Space Station (ISS) nearly had to de-man their outpost due to the fact the replenishment of consumables were uncertain. Automated Identification Technologies (AITs) such as Radio Frequency Identification (RFID) can be utilized to minimize the occurrence of situations like this one. RFID has been used to aid inventory management systems by providing real time availability of the item information including location and status. The benefit of RFID over barcodes is immense as it allows users to employ continuous review models. Barcodes are only capable of …

Evaluation Method For Strategic Investments, Olabode Alabi

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

Real Options Analysis (ROA) has become a complimentary tool for engineering economics. It has become popular due to the limitations of conventional engineering valuation methods; specifically, the assumptions of uncertainty. Industry is seeking to quantify the value of engineering investments with uncertainty. One problem with conventional tools are that they may assume that cash flows are certain, therefore minimizing the possibility of the uncertainty of future values. Real options analysis provides a solution to this problem, but has been used sparingly by practitioners. This paper seeks to provide a new model, referred to as the Beta Distribution Real Options Pricing …
