Abstract:
Requirements Traceability has a very important role in the entire application development lifecycle. As for the problem of manual creating requirement traceability relationship time-consuming and error-prone effort problem, this paper proposed a new component-based dynamic requirement traceability model. The model incorporates the requirements specification model and component functionality tree model to format requirements documents and component library. Establish requirements traceability relationships through mutual matching between component facet functional items and requirement documents. Validate requirements traceability feasibility and efficiency through multiple systems and component requirements documents, the experimental results provided by the implemented system show that the model is valid, and efficiency and accuracy have been improved to some extent compared with the conventional information retrieval model.

Abstract:
In recent years, the application of traceability systems in the food and drug industry has developed rapidly, but it is rarely used for wind turbines. From the aspects of low information transparency and information islands in the supply chain process for wind turbines, a reliable traceability system is essential. However, the existing traceability systems are not suitable to be directly applied to wind turbines. Consequently, according to the characteristics of the wind power industry, a semi-centralized traceability architecture based on Internet of Things technology was proposed. Furthermore, a traceability platform was constructed by analyzing the information collected in each stage related to various user needs of wind turbines, and various applications, including manufacturing management and spare parts management, were developed. Compared with the existing systems, the proposed platform was wind-turbine-oriented, effectively improved traceability efficiency and enterprises’ information security, and extended the length of the traceability chain by integrating the after-sales information. The traceability of key components of wind turbines during their life cycle provides a useful reference for further improving the parts quality management system of the wind power industry.

Abstract:
Origin traceability is important for controlling the effect of Chinese medicinal materials and Chinese patent medicines. Paris polyphylla var. yunnanensis is widely distributed and well-known all over the world. In our study, two spectroscopic techniques (Fourier transform mid-infrared (FT-MIR) and near-infrared (NIR)) were applied for the geographical origin traceability of 196 wild P. yunnanensis samples combined with low-, mid-, and high-level data fusion strategies. Partial least squares discriminant analysis (PLS-DA) and random forest (RF) were used to establish classification models. Feature variables extraction (principal component analysis—PCA) and important variables selection models (recursive feature elimination and Boruta) were applied for geographical origin traceability, while the classification ability of models with the former model is better than with the latter. FT-MIR spectra are considered to contribute more than NIR spectra. Besides, the result of high-level data fusion based on principal components (PCs) feature variables extraction is satisfactory with an accuracy of 100%. Hence, data fusion of FT-MIR and NIR signals can effectively identify the geographical origin of wild P. yunnanensis.

Abstract:
AbstractAdditive manufacturing (AM) is a versatile technology that could add flexibility in manufacturing processes, whether implemented alone or along other technologies. This technology enables on-demand production and decentralized production networks, as production facilities can be located around the world to manufacture products closer to the final consumer (decentralized manufacturing). However, the wide adoption of additive manufacturing technologies is hindered by the lack of experience on its implementation, the lack of repeatability among different manufacturers and a lack of integrated production systems. The later, hinders the traceability and quality assurance of printed components and limits the understanding and data generation of the AM processes and parameters. In this article, a design strategy is proposed to integrate the different phases of the development process into a model-based design platform for decentralized manufacturing. This platform is aimed at facilitating data traceability and product repeatability among different AM machines. The strategy is illustrated with a case study where a car steering knuckle is manufactured in three different facilities in Sweden and Italy.

Abstract:

The impact of computer programs in safety-critical systems has increased in the past decades and computer-based systems can now be found in a wide range of applications.

A new approach for developing dependable systems is documenting all design rationale that affects safety using Intent Specifications. A recent approach for developing complex systems efficiently and in an upgradeable manner is Component-Based System Engineering. In this thesis, these approaches are combined in the development and upgrade of a Remote Robot Control Unit by using the tool SpecTRM.

The case study showed that Intent Specifications and CBSE could successfully be combined. The tool SpecTRM was also studied during this work. It showed that traceability is of great importance during system upgrades. Since SpecTRM does not support formal verification of safety properties in design models, the SpecTRM-RL models were translated to Esterel code. Further analysis showed that functional verification can be efficient and useful when using the automatic model-checking tool available in Esterel Studio. This work also proposes a practical guideline for system upgrades in component-based systems, presented as the Sigma model.

The work also showed some shortcomings. First of all, the tool SpecTRM is at an early development stage and not yet mature for industrial use. Secondly, neither of the two languages SpecTRM-RL and Esterel was expressive enough for some of the numerical computations and data-exchange structures needed for navigation in the system. Finally, the verifier was not able to prove any data properties since valued signals are abstracted into pure signals during verification in Esterel Studio.

Nowadays, with the rise of consumer awareness, product safety and quality have been drawing more and more attentions. There have been frequent reports on defective products, resulting in large scale product recalls. Product recalls are costly and would hurt the brand image considerably. Therefore, quick responses based on product traceability are essential to modern companies. These rely on fast and accurate traceable production information. With a well planned Production Traceability System, a company can will pin-point the cause of a defect, the part, the time and situations it happened, the supplier of the defective part, and even the batch of the defective part. These help to narrow the scale of the recalls to specific batch of products. This would largely reduce the reaction time and cost, as well as effectively containing the impacts of the incidents. This study proposes a production traceability initiative, including the necessary information systems implementation for Company F, an electro-acoustic component manufacturer. Company F designs and produces micro-speakers, audio box and acoustic consumer products, to be assembled into final products like smartphones and notebook computers. Its customers are mostly international branded companies with very high levels of quality requirements. To meet the challenge brought by the increasing customer demands, the study examined the current production system, and identified changes that would increase production traceability. A Production Traceability System is also proposed. The improvements would resulted in better quality and helps to increase visibility of the production histories of productions into batches, and increase the ability to prevent defect at an early stage of production.

Dissertação de mestrado integrado em Engenharia e Gestão Industrial
A presente dissertação desenvolveu-se no âmbito do Mestrado Integrado em Engenharia e Gestão Industrial (MIEGI) e realizou-se ao abrigo de uma estreita parceria entre a Bosch Car Multimedia Portugal, S.A. e a Universidade do Minho – Innovative Car HMI. A empresa depara-se com um problema relativo à pouca rastreabilidade das suas matérias-primas o que traz inúmeras consequências, tais como, uma resposta mais demorada aos seus clientes relativamente à capacidade de satisfazer uma encomenda e maiores custos de sucata resultantes do término da validade das matérias-primas, entre outras. Neste sentido iniciou um projeto, dentro do qual se insere a presente dissertação, designado Smart Internal Supply Chain que se centra na implementação da tecnologia RFID com o objetivo de aumentar a visibilidade da cadeia de abastecimento, em particular, a movimentação de matérias-primas. O objetivo da dissertação foi procurar identificar os principais desafios da implementação de um sistema baseado na tecnologia RFID e a metodologia de investigação utilizada para o efeito foi o Estudo de Caso. Em primeiro lugar estudou-se a operação logística interna atual no que se refere à movimentação de matérias-primas e respetivas formas de rastreabilidade de forma a identificar os principais problemas. Em paralelo realizou-se uma análise bibliográfica sobre o tópico da rastreabilidade mais concretamente sobre a tecnologia RFID. A introdução da tecnologia RFID permite resolver o principal problema identificado que se refere aos poucos pontos de controlo das matérias-primas (Receção, Armazém principal e Linhas de produção) acrescentando mais quatro (Reembalamento, Área Volumoso, Milkrun e Supermercado). Além disso, permite automatizar o registo de movimentação de matérias-primas, automatizar os pedidos ao armazém principal e posteriormente permitirá otimizar diversos processos logísticos através dos dados que o novo sistema irá fornecer. Os principais desafios encontrados ao longo do projeto foram a enorme complexidade de toda a operação logística na movimentação de matérias-primas, a definição do grau adequado de granularidade de rastreabilidade, a dificuldade de integração deste novo sistema com o sistema SAP da empresa e a falta de know-how da equipa associada ao projeto sobre a tecnologia RFID.
The present dissertation was carried out in fulfillment of the thesis requirement for the degree of Integrated Master’s in Industrial Management and Engineering. It was held under a close partnership between Bosch Car Multimedia Portugal, S.A. and Minho University – Innovative Car HMI. The company faces a problem concerning the lack of traceability of its raw materials which has numerous consequences, inter alia a longer response to its clients regarding the ability to satisfy an order and higher scrap costs resulting from the termination of the shelf life of the raw materials. Hence, the company started a project named Smart Internal Supply Chain within which this dissertation was written. This project focuses on implementation of RFID technology with the aim of increasing the visibility of the supply chain, in particular, the movement of raw materials. The objective of this dissertation was to identify the key challenges of implementing a system based on RFID technology and the research methodology used for this purpose was the Case Study. Firstly, it was studied the current internal logistics operations with regard to the raw materials and its forms of traceability in order to identify the main problems. Concurrently it was reviewed literature about the topic of traceability more concretely about RFID technology since its implementation is a restriction of the company. The introduction of RFID technology allows solving the main identified problem which refers to the few points of control of raw materials (Reception, Main Warehouse and Production Lines) by adding four (Repacking, Bulky Area, Milkrun and Supermarket). Moreover, this technology allows the automatization of raw materials registration, the automatization of requests to the main warehouse and optimization of many other logistics processes through data that the new system will provide. The main issues encountered throughout the project were the enormous complexity of the entire logistics operation in the movement of raw materials, the definition of the appropriate degree of traceability granularity, the difficulty of integrating this new system with the company SAP system and the lack of know-how of the project team about the RFID technology.

Abstract:
AbstractEssential biodiversity variables (EBVs) are designed to support the detection and quantification of biodiversity change and to define priorities in biodiversity monitoring. Unlike most primary observations of biodiversity phenomena, EBV products should provide information readily available to produce policy-relevant biodiversity indicators, ideally at multiple spatial scales, from global to subnational. This information is typically complex to produce from a single set of data or type of observation, thus requiring approaches that integrate multiple sources of in situ and remote sensing (RS) data. Here we present an up-to-date EBV concept for biodiversity data integration and discuss the critical components of workflows for EBV production. We argue that open and reproducible workflows for data integration are critical to ensure traceability and reproducibility so that each EBV endures and can be updated as novel biodiversity models are adopted, new observation systems become available, and new data sets are incorporated. Fulfilling the EBV vision requires strengthening efforts to mobilize massive amounts of in situ biodiversity data that are not yet publicly available and taking full advantage of emerging RS technologies, novel biodiversity models, and informatics infrastructures, in alignment with the development of a globally coordinated system for biodiversity monitoring.

Abstract:
Monitoring the environmental performance of a product is recognized to be increasingly important. The most common method of measuring the environmental performance is the international standards of Life Cycle Assessment (LCA). Typically, measuring is based on estimations and average values at product category level. In this chapter, the authors present a framework for measuring environmental impact at the item level. Using Traceability Graph emissions and resources, it can be monitored from the data management perspective. The model can be mapped to any precision level of physical tracing. At the most precise level, even a single physical object and its components can be analyzed. This, of course, demands that the related objects and their components are identified and mapped to the database. From the opposite perspective, the authors’ model also supports rough level analysis of products and their histories. In terms of the Traceability Cube, multidimensional analysis can be applied for traceability data.

Abstract:
This new sensor project has been initiated mainly in order to take measurements in the field of biomechanics during motions of human bodies. For that, it’s necessary to detect the efforts at the contacts with these human bodies in real situation, such as during working, walking, running, biking and so on. Up to now, most of 6 components force sensors which are used, for instance are sensors with each component measuring device as perfectly as possible decoupled from each other’s. This leads to expansive or very expansive sophisticated sensors. The present sensor is a stand-alone wireless, small sized 6-axis force sensor with a powerful and precise conditioning and acquisition system. The sensitive cell is a raw Stewart mechanical structure (strain-gages based) with, conversely to usual multicomponent sensors, force and moment components not decoupled at all, but optimally coupled. Owing to the powerful numerical capabilities of the sensor, the 6 effective components of a given mechanical action are instantaneously computed. Thanks to that, even for small quantity production, the sensor cost price is significantly reduced. This reduction is bigger for larger quantity productions like for: robotics, machine tools, hoisting machines… Added to the sensor design, the project include also a theoretical mechanical research in order to find an accurate calibration method, as easy as possible to be performed. This results in calibration tests needing only a standard traction-compression test machine running with mechanical effects decoupling tools dimensioned so that the calibration relative uncertainty is kept below 1‰. With that, only 6 elementary loading tests have to be applied to the sensor. The whole sequence of calibration is done automatically, completely governed by a powerful calculation and acquisition software. All the raw tests results (strain in µm/m) are automatically collected, converted and analyzed. At the end of the numerical treatment of each set of measurements, all the calibration data attesting the traceability to the International System of units (SI) of the sensor, including : raw calibration results, sensitivities coefficients matrix needed for later data reduction and conversion in solicitation components (force and moment), sensor performances characteristic curves (non-linearity, hysteresis error curve, zero shift error, etc.), calibrations uncertainties, are stored in the computer memory. The calibration matrix is then uploaded on the sensor. So, the measurement results (values of solicitations components) are directly expressed in mechanical units traceable to SI. This sensor is able to perform high data rate wireless streaming with time-synchronization protocol or low data rate transmissions compatible with IOT connectivity. The following paper describes and comments most important engineering job sequences and calibration results. It’s also an example of future connected sensors structures able to gather, not only the staff needed to give accurate high levels measurement results, but also all the key pieces of information’s relative to the measurement traceability proof and quality management, all of them being instantaneously available on the net (IOT). This research and development job got the funding of FEDER-FSE-2014-2020 Nouvelle-Aquitaine program and of CRITT-Sport et Loisirs.

The DEMOnstration Fusion power Plant (DEMO) will be a key step towards Fusion Power Plant technology. It represents the single step to a commercial fusion power plant, in charge of demonstrating the viability of relevant technologies. Indeed, the development of tokamak sub-systems has to take into account interface, structural and functional requirements and multi-physics issues that can be completely known only during the development of the design process. This leads to difficulties to be faced during the conceptual design, mainly related to the identification of the main requirements, the change management and the sub-system integration. The Systems Engineering approach aims to support the design and management of complex systems over their life-cycles, providing a systematic approach for the definition of customer needs and required functionality from the early stage of the design, as well as for the design synthesis and the system validation and verification. Among the tokamak sub-systems, the divertor is the one devoted to power exhaust management and represents, at the same time, one of the most challenging components, in terms of materials, technologies and manufacturing. Current design activities, conducted in the in the framework of EUROfusion Consortium are in a pre-conceptual phase. Despite the early design stage, a systems engineering approach is being applied as an integrated, interdisciplinary R&D effort. The paper therefore presents the modeling effort to the conceptual design of DEMO divertor aimed at identifying both system main functions and expected behavior, given the constraints imposed from either project requirement or from current viability of technological solutions. To allow for flexibility in design needed to explore the feasibility of different solutions at this pre-conceptual stage, the impact of possible changes in high level requirement or interfaces is also investigated. This is also achieved through the allocation of the requirements to the affected components and providing efficient traceability. Therefore, the proposed modelling approach is intended to support the whole divertor conceptual design stage, allowing for requirements identification, traceability and change management.

Abstract:
In today’s marketplace, most products must better satisfy customers’ needs in the shortest time and be competitively priced. In this context, the reuse of knowledge about the targeted product is critical for developing potential product platforms. One can facilitate the reuse of existing knowledge to achieve a desired design by establishing a method that considers the layout of modules (or components) with identified flow interfaces, volume and the fundamental functional description. The problem grows with the number of candidate modules and with information-rich descriptions. The proposed REUSE (Reuse Existing Unit for Shape and Efficiency) Method greatly facilitates this search by filtering candidates based on their similarity to desired characteristics and their performance efficiency. By reusing existing information from components and modules, this approach allows the detailed specification of cost (e.g., investment and production cost for a module) along with other desired characteristics. This method applies to the complete product realization enterprise from conception through product launch. It also enables traceability of design decisions to help capture rationale and justification. A case study involving a family of cameras illustrates the proposed method.

Abstract:
Concept of the real-time hybrid model (ReaTHM® 2) testing framework for marine hybrid power plant is presented. The benefits and challenges with regard to using the model-scale power plant for the testing are explained. As a feasibility study of the methodology, tests are performed at the Hybrid Power Laboratory with a model-scale physical diesel-electric power plant. In this test, a load profile from onboard measurements from a ship is used as a numerical part of the system. In the model-scale power plant, the electrical part of the plant is used as an actuator to generate the load for the diesel engine. The traceability of the components and the total system to the given load profile is quantified in terms of time delay and tracking errors. For conclusion, the limitation of the test is analyzed and suggestions for improving the results are provided.

Abstract:
The design and certification of a high performance recuperator for micro gas turbines is presented. The component has been developed and built for a 100kWel micro gas turbine. The recuperator heated up compressed air at 3.5 bar with exhaust gas near atmospheric pressure and recuperates 300 kWth at an effectiveness of 90%. This concept can readily be adapted for other micro gas turbines due to its modular design. The certification has been realized under Pressure Equipment Directive 97/23/EC, equivalent to ASME Boiler and Pressure Vessel Code, covering closed pressurized devices. However, minor leakage in the recuperator is allowed, thus requiring an inventive design and validation approach for meeting the certification requirements. This leak is caused by weld porosity: the heat exchanging core plates are laser welded, having over 1200 meters of sealing weld length in a single recuperator. The maximum allowable leak amounts to 3 10−6 mm2 per meter weld length. The maximum leak was 0.2% of the massflow on the pressurized side at the nominal operating point, and therefore did not adversely affect the effectiveness of the recuperator. The finite element calculations and the resulting design loops on components and weld connections are presented. Validation of the entire component is done under the Experimental Design Method. A hydrostatic pressure test at 8.4 bar and ambient temperature is executed in the presence of a certified notified body to demonstrate that the welds are sufficiently robust. This pressure is higher than the operating pressure to simulate the effect of temperature on the steel properties. A laser scanner is used to map the deformation of the unit under pressure and subsequently referenced to its original state. The maximum deviation measured is equal to 0.26 mm for the pressurized part, which is acceptable considering the size of the unit is 1000mm × 600mm × 1000mm. The strain levels went back to the values before putting the unit under pressure, indicating there are no residual deformations. The test is further accompanied with leakage rate measurements before and after the hydrostatic pressure test. If the difference between these leakages rates is within limits, the recuperator will pass the test. The measured total leakage area is 0.4 mm2, well below the maximum allowable value, and equivalent to 0.01% of the massflow at the nominal operating point. This means the recuperator passed the test successfully. Furthermore, a burst test was executed to determine the safety factor and to identify the weakest element of the design. The burst pressure is observed at 18.3 bar, resulting in a safety margin of 218% and 523% in reference to the PED and operational design pressures, respectively. The component responsible for failure has been further optimized for the next generation of recuperators. Field data confirm that the lifetime of the high performance recuperator meets the requirements of 40.000 h operating time. Additionally, the traceability of the serial produced components is handled by the audited quality management system. It covers the used materials, including lot traceability, the measured process characteristics and welder certifications. The approach can also be used for ASME certification.

Abstract:
RF tags based on RFID (Radio-frequency Identification) technology have been widely used in various fields including power plant construction and maintenance for the purpose of improving the identification and traceability of the many components in the facility. To date, various types of tags have been developed, including tags that are resistant to chemicals or high-temperature environments, which are used in specialized fields. When considering widespread use of RF tags in nuclear power plants, there is a concern about the effects of radiation on the RF tags, because the data stored in the tag may receive radiation damage, resulting in corruption of data. Here, we describe a newly designed RF tag that achieves resistance to radiation damage by attaching a radiation shield layer and incorporating automatic data-correction software. This radiation-resistant RF tag has been tested under real radiation exposure fields to verify the intended radiation-resistant functions. It is expected that the use of these radiation-resistant RF tags with a data reader and database system will increase the capabilities of RF tags applied to nuclear power plants and it is also expected to lead to reductions in worker radiation exposure doses.
