Sobrinho, Osvaldo Gogliano. "Serviço de resolução e descoberta de informações sobre objetos em sistemas baseados em RFID." Universidade de São Paulo, 2013. http://www.teses.usp.br/teses/disponiveis/3/3141/tde-16102013-162918/.
Full textThis is the result of a survey intended to propose a resolution and discovery service of information about objects. In this context, objects are items of a production chain and, likely customers of the proposed service, are information systems intended for logistics management at the productive chains and/or maintenance of data on traceability of supply chains. This scenario fits perfectly to the paradigm of the Internet of Things, where objects of everyday use have active participation on the Internet. The convenience of direct exchange of information between the members and the supply chains motivates many researchers to propose the creation of data standards. One of the most relevant proposals, presented by the international organization GS1, involves the architecture specification for these systems, as well as a standard data vocabulary, the EPCglobal® Network. The use of RFID technology allows obtaining data, during the passage of items by RFID readers installed along the supply chain. The use of a standardized code in the recording of RFID tags, called the Electronic Product CodeTM (EPC), is another advantage of this technology. One of the essential features of this system is the possibility of obtaining information relating to an individual product. This information can be found not only in item producer, but also in all members of the supply chain that had access to the item. This functionality is the only aspect of EPCglobal® not yet specified by GS1. For this reason, several researchers have been working with new suggestions. The solution presented is another proposal based on the use of an implementation of a peer-to-peer (P2P) network, using the Kademlia Protocol, chosen from the comparison between the several protocols proposed in the literature, aiming at a better effectiveness. From a simulation carried out in software specially developed for this purpose, we present the details of the suggestion and the results obtained with its use.

Full textRFID technology (Radio Frequency IDentification) is an automatic identification method relying on storing and remotely retrieving data using devices (RFID tags or transponders) enabling the contactless identification of objects. RFID has been around for decades but only during the last years has become one of the most promising research areas with more and more attention focused on it. The retail sector had been leading the way with logistics applications, followed by some government agencies with identification systems and by different sectors of activity (pharmaceuticals, aircraft manufacturing, etc). Together with the last technological developments, new ideas and concepts are generating new paradigms as the "Internet of Things". The "Internet of Things" can be described as "Things having identities and virtual personalities operating in smart spaces using intelligent interfaces to connect and communicate within social, environmental, and user contexts ".1 Also during the last decades, air transportation has become more and more important for people mobility and goods transportation in the global economy environment. According to IATA , RFID can be used as a way to improve a range of airline business processes while cutting costs. IATA had developed a standard for RFID baggage tags and recommended practices and business cases for the use of RFID in baggage handling. With this study it is planed to analyse the situation in the two main airports in Portugal (Lisbon and Oporto), based in Portway ground handling operations, compare it with some actual developments, the E-Cab Project and IATA proposals and recommendations, and to evaluate scenarios and their feasibility in a near future.
A tecnologia RFID (Radio Frequency IDentification) é um método de identificação automático de armazenamento e recuperação remota de informação, recorrendo a dispositivos (etiquetas ou transmissores-receptores RFID) que permitem a sua leitura à distância e sem necessidade de qualquer contacto directo com os objectos. Sendo uma tecnologia já com décadas de existência, só durante os últimos anos é que se tem evidenciado como uma das mais promissoras , captando cada vez mais atenção por parte dos diversos actores. O sector de retalho tem vindo a promover a sua divulgação, liderando o desenvolvimento de diversas aplicações logísticas e sendo seguido, durante os últimos anos, por algumas agências governamentais com o desenvolvimento de sistemas de identificação e por diversos outrossectores de actividade (farmacêutica, construção aeronáutica, etc). Em simultâneo com os mais recentes progressos tecnológicos e com o desenvolvimento de conceitos mais inovadores, um novo paradigma tem aparecido com a designação da "Internet dos Objectos". A "Internet dos Objectos" pode ser descrita como "objectos possuindo identidades e personalidades virtuais operando em espaços inteligentes usando interfaces inteligentes para ligar e comunicar em contextos sociais, ambientais e no seio dos utilizadores". Também durante as últimas décadas, o transporte aéreo tem vindo a desempenhar um papel cada vez mais importante para a mobilidade das populações e para o transporte de mercadorias no ambiente da economia global. De acordo com a IATA, as tecnologias RFID poderão vir a ser utilizadas com sucesso, reduzindo custos e melhorando um vasto conjunto de processos correntes no sector, tendo já desenvolvido alguns normativos e recomendações relativas à aplicação de etiquetas RFID na identificação e monitorização de bagagem. Com este trabalho pretende-se analisar a situação nos dois principais aeroportos Portugueses (Lisboa e Porto), baseada nas operações de handling da Portway, comparar os resultados obtidos com os desenvolvimentos actuais resultantes do Projecto E-Cab e com as propostas e recomendações da IATA, avaliando cenários e a possibilidade da sua concretização num futuro próximo.

Full textThe term Internet of Things (IOT) describes an emerging global, Internet-based information service architecture for RFID-tagged items (Radio-Frequency Identification). In the vision of its proponents, this IOT will facilitate information exchange about goods in global supply chain networks, increase transparency, and enhance their efficiency. Name Services for the IOT are distributed systems that serve the following fundamental lookup function: Given an identifier for a real-world object, e.g., an Electronic Product Code (EPC), they return a list of Internet addresses of services, which offer additional information about this object. This thesis discusses the information security challenges involved in the design and use of an IOT Name Service (IOTNS). Our main contributions are the following: First, the requirements for an IOTNS are collected and discussed, including multilateral security and the client perspective, which have been neglected in IOT standards and research literature so far. Second, we conduct a detailed security analysis of the most influential standard Object Naming Service (ONS). This extends our previous article that initiated this new research line in the field of RFID and IOT security. Third, enhancements to ONS are discussed, which could mitigate some of the ONS security shortcomings in an evolutionary way without completely abandoning the established standard. In particular, we describe an architecture and prototype for Multipolar ONS, which reduces international dependency on a single country controlling the ONS Root. Fourth, we present a new IOTNS architecture based on Distributed Hash Tables (DHT) and its implementation on the research platform PlanetLab. This architecture is shown to offer enhanced overall security compared to ONS while delivering equivalent or even better functionality, scalability, and performance.

In this thesis, the suitability of RFID as a platform for real time applications in the Internet of Things is investigated. Two sample applications of RFID technology identify throughput and latency as key figures of merit. An experiment to measure these parameters in an existing implementation is devised and executed. The sources of latency are identified with a high degree of accuracy. Recommendations for improvement of the existing implementation are guided by the latency measurements.

By having everything in our physical world digitally connected, the Internet of Things is expected to transform how we interact with our environments and unlock tremendous business values through advance analytics. Owing to its low cost, small form factor, and its ability to communicate without a battery, RFID has emerged as a key enabler for digitally connecting, identifying, and tracking everyday objects. Each year, billions of RFIDs are being deployed to tag retail goods, track pharmaceuticals, and build smart infrastructures. However, core technical challenges in localization and data communication remain to be addressed, before RFID could reach its full potential in the Internet of Things. Today's RFID systems can only identify whether a tagged object is within radio range (up to tens of meters) while lacking the capability to pinpoint its exact location. This dissertation presents three centimeter-scale RFID localization designs, each introducing a set of new techniques and targeting a different application: 1) business analytics and asset management; 2) navigating a robot toward an RFID-tagged object and estimating its position and orientation for manipulation; 3) a virtual touch screen enabled by tracing the detailed trajectory of the RFID on an user's finger to reconstruct her drawing or handwriting in the air. Beyond locating and tracking objects, RFID also holds great potential in forming ultra-low power sensor networks to collect data. A major problem that has challenged this vision is that, unlike WiFi or cellular devices, backscatter RFIDs lack functionalities like carrier sense and rate adaptation, and hence RFID-sensor networks tend to suffer from collisions and inefficient data communication. In this dissertation, instead of considering collision as detrimental and trying to avoid it, we show how to transform collisions into a distributed code across the bits transmitted by a network of RFIDs. We leverage this collision-based code to achieve fast node identification and automatic rate adaptation, improving RFID network reliability and efficiency.

O surgimento de novas tecnologias de comunicação sem fio possibilitou o fenômeno chamado Internet Of Things. A aplicação desse conceito no ambiente de manufatura proporciona novas oportunidades relacionadas à gestão de operações na melhoria de processos, conectando objetos e computadores de forma criativa. No contexto de melhorias nas operações de manufatura, os consagrados princípios da Manufatura Enxuta (Lean Manufacturing) passam a ser cada vez mais disseminados entre os gestores de operações, reduzindo desperdícios e oferecendo benefícios generalizados aos processos analisados. Nesse contexto, o presente trabalho tem como objetivo desenvolver um sistema de monitoramento de objetos com a tecnologia RFID, dispositivos sem fio (wireless) e plug and play, para auxiliar na coleta de dados um sistema de produção, fornecendo informações de tempo e de quantidades, facilitando a execução do balanceamento de carga, do atendimento ao takt time, da avaliação de capacidade e da identificação de desperdícios no processo. O sistema proposto compreende a definição dos requisitos de projeto, o desenvolvimento de um módulo leitor RFID, de um middleware, de um banco de dados e de um software aplicativo. O sistema foi composto por micro controladores Arduino, leitores RFID e módulos de transmissão de dados sem fio Zigbee, possibilitando operação com atualizações em tempo real e com mobilidade. Por fim, o sistema foi aplicado em duas empresas dos setores automotivo e de energia, a fim de atender diferentes demandas na gestão de operações. No setor automotivo, cinco pontos de leitura foram instalados em uma célula de fabricação de yokes e os resultados mostraram que o processo não estava apto a atender o takt time definido. No setor de energia, dois pontos de leitura foram usados para analisar horas improdutivas, que compreenderam 23,4% do tempo gasto. Também verificou-se uma redução de 60% de horas-homem em comparação com o previsto em orçamento da empresa.
Abstract : The appearance of new wireless communication technologies has enabled the Internet of Things phenomenon. The application of such concept in the manufacturing environment provides new opportunities related to the management of operations in improving processes, connecting objects to computers in a creative way. In the context of improving manufacturing operations, the longstanding Lean Manufacturing principles become increasingly disseminated among operation managers, reducing waste and providing significant benefits to the analyzed processes. Considering this scenario, this study aims to develop a monitoring system using RFID, wireless, and plug and play technologies in order to help data collection in a production system, providing information about time and quantities, enabling process waste identification, production according to takt time, activity balance, and production capacity assessment. The proposed system comprises the definition of design requirements and the development of a RFID reader, a middleware, a database, and a software. The system is composed by Arduino micro-controllers, RFID readers, and wireless Zigbee transmission modules, enabling operations with real-time updates and mobility. The system was applied in two companies from automotive and energy sectors, in order to answer different demands in operations management. In the company of the automotive sector, five reading points were installed in one cell that manufactures yokes, and the results show that the process is not able to reach the takt time. In the company of the energy sector, two reading points were used to analyze unproductive hours, which comprised 23.4% of the time spent. It was also verified a reduction of 60% in man-hours in comparison with what was predicted in the company's budget.

Full textThis dissertation discusses the possibilities of product localization based on Internet of things technologies. A model for product localization has been proposed based on RFID technology and wireless sensor networks. Within the model, a hybrid localization method which combines outputs from nearest neighbours method and particle swarm optimization for product localization has been proposed and developed, followed by a hybrid localization method which combines data from RFID system and wireless sensor network. The application possibilities for the proposed model have been experimentally tested in simulated systems and in laboratory conditions with industrial elements.

Full textPurpose: This study aims to explore how Internet of Things could be integrated in manufacturing companies to reduce the potential inadequacy in an information flow. To achieve this, two research questions were formed:
Method: A pilot study was conducted to help the authors create a picture of the study's problem area. Later a literature study and a case study were conducted. The literature study was conducted to create the theoretical framework and included areas such as Internet of Things, information, communication, information flow and information systems. The case study conducted at a large manufacturing company and was consisted document studies, observations and a focus group. The results of the study are generated through a pairing of the theoretical framework and empirical study.
Findings: The company's information flow was complex and contained a lot of manual management of information and communication. This turned out to create consequences for the information’s reliability, relevance, and timing. It has therefore been found that there are improvement opportunities through an integration of IOT in the information flow. A digitalization of an information flow can lead to creation of standard process and a larger and safer amount of shared information.
Implications: The study contributes theoretically by evaluating how IOT can contribute to innovative ways of working with information flows at manufacturing companies; this by analysing key aspects of a current information flow and IOT. Practically, the study contributes to identifying potential improvements by integrate IOT in a corporate information flow. Limitations: The study is of a one-case-design which limits generalisability. Therefore, other companies may need to examine their specific requirements before taking advantage of the study. The generalization increases slightly due to the broadness of the term IOT and that it can be applied in a wide range of areas. The method chapter has been carefully designed and described to increase the study's reliability.

Full textRadio Frequency Identification (RFID), which allows for the simultaneous identification of several objects without line of sight or human interaction, promises to significantly improve supply chain efficiency. The attention researchers and practitioners are giving it, as well as the spread of RFID technology, has increased substantially in the last few years. Although the highest potential to take advantage of this spread is expected to be realized in cross-company applications, the status quo in the RFID project landscape is dominated by local solutions within companies or pilot projects. Reasons for this phenomenon include high investment and operational costs as well as missing standards. While cross-company applications exacerbate the need for standards, they make it possible to overcome the cost problems. In the course of using a collaborative RFID application, it is possible to reduce the costs for the individual player by distributing them between a larger number of participants and repeatedly using the same tag across multiple supply chain steps. For this reason, a model for cost-benefit sharing – including different categories of compensation as well as temporal dependencies during the life cycle of an application – is developed. Apart from these organizational dimensions of cross-company RFID applications, the technical dimension has to be investigated because missing technical standards are still an obstacle for the wider adoption of RFID. Three remaining problems are solved in this thesis: (1) generating RFID events does not only require the data that is provided by the RFID readers, but also corresponding context data; (2) the EPCglobal network provides the technical basis for the Internet of Things, but not the applications that might profit from using this architecture; and (3) there is no standardized approach for storing user generated content besides the EPC on the RFID tags.

Full textVi kollar ofta våran virtuella brevlåda flera gånger om dagen men glömmer ofta att kolla vår faktiska brevlåda hemma. Målet med det här projektet är att skapa en smart brevlåda. Denna definieras som en brevlåda som kan meddela mottagaren att ett brev har kommit och öppnas åt rätt person. Meddelande-processen sker genom att en streckkodsläsare skannar inkommande brev och identifierar mottagaren. Sedan skickas ett e-postmeddelande till dem, som meddelar att ett brev anlänt. En undersökning av olika typer av streckkoder har genomförts med slutsatsen att Code128 var den mest lämpliga att använda för detta projekt. Skanningsnoggrannheten av brevlådan testades och visade att en användare bekant med konceptet kunde skanna ett brev korrekt 90% av försöken. Att ge åtkomst till rätt person gjordes med Radio frequency identification (RFID), genom att använda en RFID-läsare och RFID-brickor. Brevlådan programmerades på det sättet att skannandet av den auktoriserade brickan gav tillgång till innehållet av lådan genom att låsa upp och öppna locket. Den slutgiltiga produkten är ett koncepttest av en smart brevlåda. Dess syfte är att visualisera och testa våra teorier. Det här projektet ämnar också att bevisa fördelarna med att implementera mer information i standarden för IMB (Intelligent mail barcode)

O conceito da Indústria 4.0 está relacionado à evolução dos sistemas produtivos através da interconexão e integração total entre tecnologias de automação industrial e tecnologia da informação visando a obtenção de maior eficiência, qualidade e produtividade. Nesse contexto, uma tendência recente no ambiente industrial tem sido a utilização conjunta da Identificação por Rádio Frequência (RFID) e a da Internet das Coisas (IoT) na busca da melhoria dos seus processos de manufatura. O principal desafio é promover a integração entre essas tecnologias, de forma que os dados estejam disponíveis sob demanda e em tempo hábil para que as melhores decisões de produção sejam alcançadas. Este trabalho utilizou o RFID e a IoT para o desenvolvimento de uma solução para o monitoramento da produção e da eficiência de um sistema de manufatura flexível (FMS). O desenvolvimento do projeto consistiu em três etapas: aquisição dos dados RFID, processamento para obtenção dos parâmetros de produção e eficiência requeridos e disponibilização em nuvem para a IoT. Etiquetas RFID alocadas nas peças e nos pallets de movimentação permitiram o monitoramento da produção por meio da medição dos tempos de produção e transporte de cada peça produzida no FMS. O cálculo do indicador OEE (Overall Equipment Effectiveness), através dos índices de Performance, Qualidade e Disponibilidade, permitiu o monitoramento da eficiência das estações de trabalho e do FMS. A disponibilização dos dados da aplicação em nuvem de forma padronizada e acessível a outros sistemas foi realizada através da IoT, com a utilização do ScadaBR usando comunicação via serviço web SOAP. Experimentos foram realizados com a produção de peças diferentes (branca, vermelha e preta) e com quantidade de pallets diferentes. Análises estatísticas dos resultados de tempos de produção e de transporte permitiram quantificar erros ou anormalidades na operação do FMS. Resultados relativos ao indicador OEE permitiram o monitoramento e melhoria da eficiência do processo de manufatura.
The Industry 4.0 concept is related to the evolution of production systems through the interconnection and integration between industrial automation and information technology in order to obtain greater efficiency, quality and productivity. In this context, a recent trend in the industrial environment has been the joint use of Radio Frequency Identification (RFID) and Internet of Things (IoT) seeking for improvement in their manufacturing processes. The main challenge is to promote the integration between these technologies, so that the data is available on demand and in real time so that the best production decisions are achieved. This work used the RFID and IoT for the development of a solution for the monitoring of the production and the efficiency of a Flexible Manufacturing System (FMS). The development of the project consisted of three steps: acquisition of RFID data, processing to obtain the required production and efficiency parameters and availability of this data in the Cloud for the IoT. RFID tags allocated in the parts and conveyor pallets allowed production monitoring by measuring the production and transport times of each produced part in the FMS. The calculation of the OEE (Overall Equipment Effectiveness) indicator, through Performance, Quality and Availability indexes, enabled the monitoring of the efficiency of workstations and the FMS. The real-time availability of application data in the cloud in a standardized and accessible form to other systems was performed by IoT with the use of ScadaBR via web service SOAP communication. Experiments were carried out with the production of different parts (white, red and black) and number of pallets. Statistical analysis of the production and transport times allowed to quantify errors or anomalies in the operation of the FMS. Results for the OEE allowed monitoring and improving the efficiency of the manufacturing process.

Full textComplex is undoubtedly the adjective that best summarises the issue of the normative architecture of the Internet network. This issue is complex for two reasons. The first one results from the identification of the rules that make up this architecture and the second one from their purpose. First of all, the identification of the rules proves to be an extremely complex matter, since this concept of the rule is not so easy to define, as it refers to such a wide range of realities. After establishing the existence of the rules which set the behaviour of network builders, it is necessary to raise the question of the the nature of the rules. Here again, solving this issue is not as easy as it seems. In fact, in literature there is no universal way to distinguish the various types of rules. Secondly, the rules that compose the normative architecture of the internet aim at organising the digital society. Yet, this is a complex system. If one accepts the idea, one has to correlatively claim that the rule-complying scheme that enables such a system to be controlled is very different from that which rules more common rules for us, such as the rules of law. While the former is underpinned by a self organising mechanism, the creation of the latter stems from an act of willing. The difference between both schemes is significant: in the first case spontaneity controls the setting up of rules of conduct, while in the second case reason does. The opposition between these two normative schemes can be found in the digital universe too. It is conveyed by the existing competition between the digital and the legal orders. That is why the normative architecture of the Internet network will be described through the competition between these two normative systems

Full textThe next-generation Internet points to a scenario where trillions of objects and people are interconnected and accessible anytime and anywhere. One of the pillars of this new generation is the paradigm known as Internet of Things. This paradigm has attracted research in different domains, including, health, industry, logistics, smart cities, smart homes and agribusiness. In the context of agribusiness, the Internet of Things has advanced in applications of traceability of supply chains with products of high added value, for example, the wine chain. However, the development of applications for traceability in the wine supply chain is not supported by an architecture Internet of Things-based. In addition, current supply chain traceability systems do not broadly address the Internet of Things paradigm in its premise of interconnection among chain agents. Thus, this thesis proposes a layered architecture based on the Internet of Things paradigm for traceability of the wine supply chain. To do this, requirements were surveyed, the identification of the stakeholders in the system their concerns, identification of quality attributes and the relevance of each one of them. A candidate system was implemented in a real case for the refinement of architectural components. The evaluation of the architecture proposed in different parameters shows its adequacy both to the Internet paradigm of Things and to the needs of the stakeholders of the wine supply chain. In this way it is possible to affirm that the systems implemented from the proposed architecture are scalable, secure, adaptive, available and that support the interconnection between the agents of the supply chain, from its wine production to its disposal.

Full textDe rådande klimatförändringarna ställer nya krav på företag att ta ansvar för sina utsläpp och miljöpåverkningar. Därför blir det allt mer vanligt för företag att medvetet öka hållbarheten i sina värdekedjor eftersom det också blir allt viktigare för stakeholders och konsumenter. För att kunna sätta press på företag krävs dock transparens och med komplexa värdekedjor kan detta vara svårt att skapa. Därför krävs nya teknologier som kan hjälpa företag att öka transparens, effektivitet och integritet. Blockchain-teknologi är en relativt ny teknologi som med sina decentraliserade egenskaper har potential att användas i värdekedjan för att öka hållbarhet och transparens. Denna studie undersöker just det genom en fältstudie i den Sydafrikanska vinindustrin. Det är in riktadpå främst små- och medelstora företag och inkluderar också industriorganisationer för att bidra med en holistisk bild av värdekedjan för vin. Genom intervjuer, observationer och sekundärdata samlades empirisk data in och analyserades med tematisk data-analys. Resultaten visade att små-och medelstora vinproducenter fäktas med mycket administrativt arbete och har svårt att vara ekonomiskt hållbara på en global marknad. Spårbarheten i Sydafrika fungerar utmärkt och därför finns det redan viss infrastruktur på plats i landet som skulle kunna vara en grund till att utveckla ett blockchain-baserat system för att öka säkerheten, transparensen och minska administrativa kostnader för de mindre företagen. Ifall ett blockchain-system skulle implementeras skulle det troligtvis inte drivas av de små företagen även fast de hade gynnats mest, utan av större företag med finansiell kapacitet.

Full textOne of the challenges of the Internet of Things and, more in general, of every wireless sensor network is to provide electrical power to every single one of its smart nodes. A typical solution uses batteries but various major concerns reduce the long-term feasibility of this approach (limited lifetime, maintenance and replacement costs, and environmental footprint).This thesis develops a possible solution based on the wireless transmission of power. A complete RF harvester composed of an antenna, a UHF rectifier and a step-up voltage converter is presented. This system captures electromagnetic waves and converts them to a stable DC voltage to supply power to common logic circuits like microcontrollers and sensors. The lack of an internal battery provides an extended flexibility, especially when its replacement is not a viable option (ex. implanted devices, large number of nodes, dangerous environments, etc.). An in-depth study of integrated Schottky and CMOS UHF rectifiers is carried out; various topologies and optimizations are analyzed. Moreover, the use of an additional step-up converter is proposed in order to increase the system output voltage; an early discrete implementation and a final, more compact, integrated version are discussed and tested. These developments lead to a complete system capable of potentially powering an application with an off-the-shelf microcontroller

Full textThe importance of a well-functioning supply chain that can handle materials and services in the most efficient way possible is increasing. According to several studies it is the supply chains that compete with each other rather than the companies themselves, which implies requirements for competitive chains. This can be done by integrating the activities in the supply chain with each other, in order to minimize waste of valuable resources. The development of technology has enabled effective integration through automation. Implementation of automation in the supply chain increases the ability to integrate different activities within the chain, as it, among other things, enables data collection of information that can be shared and spread throughout the entire supply chain. The purpose of this study is to map and analyze the material supply chain at LKAB, followed by investigating whether, through automation and development of the consisting processes of the supply chain, they can improve their productivity. The study focuses on all the activities in the material supply chain, from the hub that is currently in use, to the internal end customer, which are the employees at LKAB. The purpose of the study is to develop concrete proposals that are well adapted to the company's environment and with focus on the internal end customers. Based on the image of the current situation, developed using interviews, observations and reviews, along with the conducted literature study, the different activities of the supply chain were analyzed. Through the analysis it was noted, among other things, that the work performed in the hub is not integrated with the remaining parts of the supply chain. In addition to this, it was found that the current procedure of work at the central warehouse, and especially the goods reception, involves a lot of manual but necessary work. The literature study was then used to evaluate and identify possible solutions to streamline these processes in order to achieve increased productivity in the supply chain. Through the study, it was found that automation leads to an increase in productivity though, among other things, relieving of manual work, increased labor productivity and reduced lead times. Based on this, three different automation solutions, barcode, RFID and IoT solutions were studied and analyzed. The results from this showed that the three different solutions have different advantages and challenges linked to an implementation at the case company. Out of the three solutions, barcodes are considered to be the least advantageous but it also involves the least amount of challenges, while RFID and IoT are more beneficial but in turn are connected to greater challenges. The recommendations to LKAB are firstly to optimize the already existing work with cross docking performed at the hub. This by developing the division of goods to reduce the dual processing of goods in the supply chain. The second recommendation to the case company is to implement RFID, and IoT marking of goods, to minimize manual handling, increase traceability, and increase flexibility. An implementation of these recommendations will also enable some parts of the incoming goods to no longer require being handled in the central warehouse. These parts include the goods that are to be delivered directly to the internal end customer and thus not being stored.

In order to the manage requirement of large numbers of objects, RFID-based system and Internet of Things (IoT) network have promptly become popular in recent years. Therefore, the research of the lightweight RFID authentication is considered of great importance. Recently, Morshed et al. proposed an authentication scheme, called SUAP3, to achieve the security and efficiency under ubiquitous RFID-based systems. Later, Safkhani et al. and Wang et al. had demonstrated that SUAP3 is insecure against full-disclosure attack and tag traceability attack. However, these attacks are based on powerful assumptions, and the feasibilities of the two attacks are thus a little doubtful. In this paper, we present a real passive tag-tracking attack without any specific assumptions. An adversary can exploit a series of challenge-response procedures to derive the secrets maintained at the tag. With the cryptanalysis proposed by us, the insecurity of SUAP3 is truly proved. For better robustness, we introduce a security enhanced scheme SUAP+ with the same order of the computation complexity as SUAP3.

In recent years, the internet of things (IoTs) has been a focus of research. Radio Frequency Identification (RFID) is one of the key technologies of the IoTs. It uses radio waves to enable fast and automatic identification of different objects. With the growth of wireless communication technology a mobile devices(e.g., notebook computer, PDA and smart phone) are growing rapidly, so mobile readers are used more and more increasingly. However, the mobile RFID technology may suffer from some security and privacy threats. The wireless channels between readers and server are insecure, thus, it brings higher security and privacy requirements for RFID systems. How to secure mobile RFID service in IoTs environments is important. The existing RFID authentication schemes still are vulnerable to many security attacks and privacy disclosure threats. In this thesis, we proposed a secure mutual authentication protocol for resource-constrained mobile RFID systems under insecure wireless communication environments. It can resist various attacks in RFID systems, and it can protect the privacy of mobile reader holders. Finally, we analyze and compare with several existing work, the results show that our proposed authentication scheme is more suited than the other related works for the mobile RFID system in IoTs environments.

Recently, the development of Internet of Things (IoT) takes more attentions and concerns in the world. The smart objects based on radio frequency identification (RFID) is a very important technology. Now, a wide range of RFID applications, including transportation, access control management, and industrial supply chain management, etc.. However, the RFID system also has many security and privacy issues. Recently some scholars presented various authentication protocols to enhance the security of RFID systems. In 2008, Y. C. Lee et al. proposed an RFID authentication protocol with privacy protection. Although it can achieve higher security, it is also relatively high in terms of computational cost and communication cost. In this paper, we will propose an RFID security authentication protocol with low computational cost in the tag. We can use the security smart reader to achieve the security of forgery prevention, two-way authentication, protecting privacy, replay attack and forward secrecy. Our authentication protocol is more suitable for use in the IoT environment.

Faced with customers demanding more customized products delivered at mass production prices, firms must reengineer their current business practices to a real-time enterprise (RTE) operational model to achieve flexibility in production and responsiveness to changing customer demands. To manage RTE effectively, firms must develop information system capable of managing dynamic business processes and operations in real time and taking immediate action to resolve disruptions. Radio Frequency Identification (RFID) technology and the Internet of Things (IoT) infrastructure are considered one of the most promising solutions for managing product customization as they enable firms to manufacture variants of product at a batch size of one and to effectively track and trace components and products across supply chain(s). On the other hand, intelligent agent based technologies have the capability to deal with the dynamic system of RTE and play a key role in integrating RFID with business processes to better manage an RTE. However, IoT/RFID and intelligent agents are two complex research fields and to build a RTE based on the two technologies is a major challenge facing many enterprises today. That problem indicates that there is a lack of coherent system modeling and design methodology for RTE systems. Towards the solution of this problem, the main objective of this research is focus on developing a unified yet comprehensive system modeling and design methodology to build a RTE based on the IoT/RFID and intelligent agents. Several challenging problems associated with the modeling and design of IoT/RFID and agent based RTE are: (1) how to analyze and develop IoT/RFID-driven processes and system model(s); (2) how to design and apply high-level agent social model(s) on the IoT/RFID system model so that controlling scopes of agents and agent-interaction schemes can be defined for IoT/RFID process management; and (3) how to develop internal cognition and control models of agents defined in the high-level agent social model so that they can be implemented and employed to effectively manage IoT/RFID-driven operations of a RTE. The proposed methodology in this thesis addresses the system modeling and design challenges present in building IoT/RFID and agent based RTE in a top-down approach: (1) Developing IoT/RFID process analysis and system modeling schemes and algorithms so that IoT/RFID-driven process and system models can be constructed and verified; (2) Developing agentification methods to build a high-level agent social model based on the IoT/RFID system model; and (3) Based on the high-level agent social model as a guide, devising agent’s internal cognition and control models using BDI (belief-desire-intention) reasoning model and agent-oriented hierarchical state-feedback Petri net approach. An implementation framework is also proposed to address the implementation issue. The key contribution of this thesis is to present a unified modeling and design methodology for building IoT/RFID and agent based RTE systems. To demonstrate the methodology’s real-world applicability, prototypical systems consisting of intelligent-agent based IoT smart end-point devices and real-time enterprise applications are developed to substantiate the applicability of the proposed methodology and to serve as a reference model for developing RTE systems. Results of prototype experiments also demonstrate that the proposed IoT/RFID and agent based RTE system is more capable than most current industrial practices in managing dynamic enterprise operations, automating manufacturing and logistic processes, and reducing work-in-process inventory and labor cost.
