“…Quanto ao inventário, verifica-se que esse pode ser parametrizado pelos usuários da TI, facilitando a localização dos produtos. Bertolini et al (2012) concluíram que os inventários tiveram uma contagem mais rápida e com mais precisão na informação via uso de TI. Isso ocorre porque a TI permite que se tenha informação em tempo real dos estoques, alinhamento e programação das operações entre as firmas e seus fornecedores, melhorando a coordenação entre elas (Prajogo e Olhager, 2012, p. 515-516).…”

Avaliação de Tecnologias da Informação: o PSL e a TransportadoraResumo O objetivo do artigo é avaliar as Tecnologias da Informação (TI) em duas organizações que prestam serviços logísticos para uma empresa do setor de telecomunicações, por meio de um grupo de atributos de avaliação de TI da revisão de literatura. O método empregado foi o de estudo de caso múltiplos, com uma abordagem qualitativa e entrevistas semiestruturadas em um Prestador de Serviço Logístico (PSL) e em uma transportadora de um mesmo segmento (telecomunicações). Quanto aos resultados, as TI avaliadas pelos respondentes tiveram melhor desempenho nos atributos operacionais. Isso ocorreu porque as TI avaliadas (Warehouse Management System -WMS e Transportation Management System -TMS) são usadas em atividades logísticas bastante operacionais e porque as empresas as implantaram há bastante tempo. Percebeu-se, também, que a avaliação das TIs foi influenciada pela sua utilidade para as operações das empresas. Palavras-chave: Avaliação; Tecnologias da Informação; Prestadores de Serviços Logísticos;Transportadora; Telecomunicação. AbstractThe paper aims to assess the Information Technologies (IT) related to two companies, which supply logistics services to a telecommunication company, through a set of attributes of IT assessment from the literature review. The multiple case study method was applied with a qualitative approach, and semi structured interviews with a 3PL Provider and a carrier in the same sector (telecommunication). Regard to the issues, the ITs assessed by respondents had better performance in the operational attributes. This happened because the ITs that were evaluated (Warehouse Management System -WMS e Transportation Management System -TMS) are used in logistic activities, which are operational enough, and because the companies implemented them a long time ago. We also perceived that the ITs assessment was influenced by their utility for the companies' operations.

“…RFID is an Auto Identification and Data Capture (AIDC) system that carries information around using radiofrequency waves that presented a global revenue of 11.2 billion dollars in 2017 [1,2]. This technology, especially the specified by ISO 18000-6c and operating at the ITU Region 2 frequency band, 902-928 MHz [3], has been increasingly adopted in sectors like apparel retail, assets and supply chain management, logistics and transports [4][5][6][7]. Microstrip antennas (MSA) are used in several wireless applications, being present in aircrafts, spacecrafts, missiles and satellites, for example [8].…”

“…All these features made the MSA the most popular one for RFID readers operating in the UHF band [12]. Commonly, MSA presents gains ranging from 6-9 dBi, according to [8,12,13], being it sufficient for the use of RFID in medium and short range applications like apparel, retail and supply chain management, for instance [6,7]. Nevertheless, several long-range RFID applications like the automatic identification of cars and trucks in tolls and parking spaces, as seen in [4,5], require long-range RFID communication.…”

“…Therefore, it is in that context that comes the idea to develop a novel general-purpose single element MSA that can be used in short and medium range communications for RFID applications [6,7], an also novel NIM superstrate acting as a planar focusing lens, and the combination of both, forming a novel, light, small, low-cost, gain-enhanced antenna for long-range RFID applications [4,5], using the 902-928 MHz frequency band. This development contributes to reducing the expensive costs of the needed infrastructure [22], pushing the RFID adoption in a wide range of applications globally.…”

A novel gain-enhanced microstrip antenna (MSA) with metamaterial planar lens for longrange radio frequency identification (RFID) applications for the 902-928 MHz UHF frequency band is proposed in this paper. The antenna is a combination of a new general-purpose circularly polarized MSA and a novel effective negative refractive index metamaterial (NIM) slab of 25 unit cells, arranged in a 5 × 5 layout, working as a planar lens for gain enhancement. The general-purpose MSA has an impedance frequency band of 828-1015 MHz, a maximum gain of 8.43 dBi at 915 MHz, an axial ratio frequency band of 896-931 MHz, and excellent performance for short and medium range RFID applications. The new infinite periodicity NIM slab has a negative refractive band of 886-1326 MHz, a negative electric permittivity band of 888-3406 MHz, and a negative magnetic permeability of band 885-1065 MHz. Together, the general-purpose MSA and the NIM planar lens results in the low-cost gain-enhanced antenna for long-range RFID applications, with an 843-993 MHz impedance frequency band and a maximum broadside gain enhancement of 48.27%, resulting in a 12.5 dBi gain at 902 MHz. Finally, the parametric studies conducted during the design process of the gain-enhanced antenna with metamaterial planar lens are presented.
