Radio Frequency Identification (RFID) is revolutionizing business practices across industries worldwide as means for its commercial application continue to be developed. It is surpassing barcoding as the preferred means of product identification due to its’ ability to identify goods at item-level as opposed to batch- or type identification, and with no line-of-sight requirements for item detection. Although many industries have successfully employed the technology and are reaping the rewards, RFID’s adoption in the truck tyre industry is still in its infant stage. A small number of documented cases discuss the limited roll-out and testing of RFID effectiveness in satisfying the demands and expectations associated with this specific application. This study is aimed at evaluating the viability of introducing RFID to the South African market. The market readiness is reflected in the perceptions of Continental Tyre South Africa’s (CTSA’s) customers regarding the perceived benefits of RFID. More importantly, it is revealed in how it affects customers’ buying behaviour and, by implication, the impact on CTSA’s sales. The results of the study also reveal critical aspects unique to the South African truck tyre market which could potentially be addressed through the introduction of RFID. These aspects form the basis of the conclusions and recommendations for future actions by CTSA.

A aplicação de RFID para processos industriais tem uma abordagem estratégica, objetivando a melhoria da satisfação dos clientes e criar novas oportunidades de negócios, bem como uma abordagem operacional com foco na eficiência operacional e na flexibilidade dos processos. A tecnologia é aplicada na logística e nos demais processos da cadeia de suprimentos com o objetivo do rastreamento dos materiais, aumento de visibilidade, aumento da eficiência operacional, redução dos desvios do processo e aumento da acessibilidade do inventário. Neste cenário, a presente dissertação tem como objetivo a avaliação de projetos logísticos aplicados à indústria aeronáutica brasileira com o uso do AHP - Analytic Hierarchy Process com ratings - passando pela identificação e avaliação das características que motivam e restringem a utilização da tecnologia através de uma revisão da literatura e pesquisa de campo / Research on Radio Frequency Identification technology (RFID) has become an important issue since 2006 and several authors have begun to assess this technology. The application of RFID to industrial processes has a strategic approach, seeking to improve customer satisfaction and new business opportunities, and has an operational approach focusing on operational efficiency and flexibility of the processes. There is a great application of RFID in logistics, warehouse and supply chain processes seeking tracking materials, increase supply chain visibility, labor savings, shrinkage reduction and inventory visibility. In this scenario, this paper aims to evaluate logistics projects applied to the brazilian aircraft industry using the AHP - Analytic Hierarchy Process with ratings, in addition to the identification and evaluation of the characteristics that motivate and restrict the use of technology through a literature review and a survey

Orientador: Barbara Stolte Bezerra / Banca: José Souza Rodrigues / Banca: André Luiz Barbosa Nunes da Cunha / Resumo: O objetivo desta pesquisa consiste em identificar e analisar as variáveis internas e/ou externas que se caracterizam como sendo fatores na adoção da tecnologia RFID no controle de estoques de materiais, especificamente nas áreas denominadas almoxarifados em usinas pertencentes ao setor sucroalcooleiro no atual cenário produtivo e econômico nacional. A escolha de usinas do setor sucroalcooleiro foi devido a relevância econômica que representou no ano de 2013, 2% do PIB nacional, montante este equivalente a US$ 43 bilhões, e tendo o valor bruto movimentado pela cadeia superior a US$ 100 bilhões. Para tanto foram empregados os métodos de revisão bibliográfica e survey. Como principais resultados foi possível observar que em um universo de 32 respondentes com cargos de liderança, 12,5% dos respondentes desconhecem a tecnologia RFID. De um total de 28 respondentes que demonstraram conhecer a tecnologia, 100% retornaram não ter a tecnologia implementada em suas operações, somente 28,6% entendem que a empresa já tenha avaliado em algum momento a possibilidade de implementação, e 60,7% acreditam que a implementação seja uma operação complexa, demonstrando que estes fatores contribuem negativamente para a adoção da tecnologia nas operações de almoxarifados em usinas. / Abstract: The objective of this research is to identify and analyze the internal and/or external variables that are characterized as being factors in the adoption of RFID technology in the control materials inventory, specifically in the areas called stockrooms in plants belonging to the sugarcane sector in the current production scenario and national economic. The choice of plants of this sector was due to the economic importance which represented in 2013, 2% of GDP, this amount equivalent to US $ 43 billion, taking the gross busy the upper chain to $ 100 billion. Therefore, we used the methods of literature review and survey. The main results we observed that in a universe of 32 respondents with leadership positions, 12.5% of respondents are unaware of the RFID technology. A total of 28 respondents who knew about the technology, 100% returned not have the technology implemented in its operations, only 28.6% believe that the company has been evaluated at some point the possibility of implementing, and 60.7% believe that implementation is a complex operation, demonstrating that these factors negatively contribute to the adoption of technology in warehouses operations in plants. / Mestre

Millimeter-wave Substrate Integrated Waveguide (SIW) technology presents itself as the most viable solution for the development of RF systems. It is a cost-e ective solution, suitable for mass production of such systems. Like planar circuits, SIW structures are compact, light weight and easy to fabricate. They also preserve some of the major advantages of metallic waveguides, namely, low loss, high quality factor and high power handling capabilities. In RF systems, rectangular waveguide horns have found various applications due to their exceptional radiation properties. From their simple construction, ease of ex- citation, usefulness and high gain, they are readily used as feed component in various RF systems, they also aid as the standardization for calibration and gain measure- ments of other high gain antennas. We are aware that, in an H-plane horn antenna, the rectangular waveguide is flared in the direction of the H-field. A large aperture in the H-plane presents the narrower half power beamwidth whereas a small aperture in the E-plane gives a wider beamwidth. In this research, the design of a SIW H- plane horn antenna with approximately symmetric half power beamwidths in both the E- and H-planes is proposed, using the commercially available electromagnetic field solver CST Microwave Studio to design and simulate proposed antenna characteristics and performance. Also, radiation patterns are analyzed and in order to validate the simulation results, measurements are performed on a fabricated prototype antenna. / Graduate

The major advantages of radio frequency identification (RFID) technology over barcodes are that the RFID-tagged objects do not require to be in line-of-sight with the reader for their identification and multiple objects can be read simultaneously. But when multiple objects are read simultaneously there is always a problem of collision which reduces the efficiency of the system. This thesis presents a comprehensive study of the dynamic framed slotted ALOHA (DFSA)-based anti-collision multi-tag identification algorithms for passive RFID system. Performance of various DFSA algorithms is compared through extensive simulation results. In addition, a number of simple performance improvement techniques have also been investigated in this thesis, including improved estimation techniques for the number of tags in each read cycle and a low-complexity heuristic stopping criterion that can be easily implemented in the practical system.
