Повний текст джерелаUtvecklingen av teknik inom tillverkningsindustrin och utvecklingen av Industri 4.0 har medfört att begreppet modellbaserad definition (MBD) har vunnit mark, eftersom den strävar efter att eliminera användning av ritningar och utspridd data, genom att skapa en enhetlig digital informationskälla. Scania har tidigare inlett arbetet med att digitalisera data, metoder och processer för enskilda komponenter inom tillverkningssektorn. Syftet med detta projekt är att undersöka vilka krav som gäller för montering av komponenter på sammanställningsnivå, potentiella fördelar och utmaningar med MBD innan det implementeras. Genom att analysera intervjuer och frågor, presenteras företagets behov. Utifrån detta ger vi rekommendationer för hur Scania ska kunna övergå till helt till att använda 3D-modeller. Slutsatsen är att den nuvarande datahanteringen har brister och att MBD kan tillhandahålla lösningar för att förbättra effektivitet, produktkvalitet och minska risken för fel.

Повний текст джерелаAs of today at Scania, the 2D drawing is the primary way to convey, forward, and store information regarding a product through its lifecycle. Since the 90’s however, this has come to change, bringing more and more popularity to discard the 2D drawing and instead present the product and all of its annotations in a 3D environment, a method known as Model Based Definition or MBD. MBD has become a game changer in the manufacturing industry, as the cost curve has declined for several companies that have implemented the method. This thesis was conducted at Scania CV AB in Södertälje, Sweden, in order to investigate the impacts of implementing MBD in an automotive manufacturing organization. Over 30 interviews and observations took place at Scania, as well as investigating three external organizations with similar backgrounds. The results were compiled and analyzed with a theoretical framework, covering the interconnected disciplines of MBD. The findings suggest that an implementation is indeed possible and that the benefits outweigh the predicted challenges that come with an implementation. The main benefits were related to concurrent engineering, as MBD integrates downstream departments at an earlier stage. It was also deemed that a single source of truth is greatly beneficial for every department, as this counteracts ambiguity that otherwise occurs when using both 2D and 3D. As MBD has great influence in most of Scania’s departments, guidance for how and when to conduct the change management was also presented.

Instrument systems such as imagers, radars, spectrometers, and radiometers are important to users in the astronomy, Earth science, defense, and intelligence communities. Relatively early in the development cycle, performance requirements are defined at the top level and allocated to various subsystems or components. This is a critical step, as poor requirement definition and resulting requirement instability has historically led to increased cost and, in some cases, program cancelation. Defining requirements for instrument systems is uniquely challenging in part due to the divide between system users (e.g. scientists) and system designers (e.g. engineers). The two groups frequently differ in terms of background, objectives, and priorities, and this disconnect often leads to difficulty in evaluating and resolving requirement trade-offs. The objective of this thesis is to develop a model-based approach to requirement definition that addresses the above challenges. The goal of the methodology is to map science objectives to a set of top-level engineering requirements in a manner that enables traceability in the requirement hierarchy and facilitates informed trades across the science/engineering interface. This is accomplished by casting the requirement definition process as an optimization problem. First, an executable instrument model is created to capture the forward mapping between engineering decisions and science capability. The model is then exercised to find an inverse mapping that produces multiple sets of top-level engineering requirements that all meet the performance objectives. A new heuristic optimization algorithm is developed to carry out this task efficiently and exhaustively. Termed the Level Set Genetic Algorithm (LSGA), this procedure identifies contours of equal performance in the design space using an elite-preserving selection operator to ensure convergence, together with a global diversity metric to ensure thorough exploration. LSGA is derivative-free, parallelizable, and compatible with mixed integer problems, making it applicable to a wide variety of modeling and simulation scenarios. As a case study, the model-based requirement definition methodology is applied to the Regolith X-ray Imaging Spectrometer (REXIS), an instrument currently in development at MIT and scheduled to launch on NASA's OSIRIS-REx asteroid sample return mission in the fall of 2016. REXIS will determine the elemental composition of the target asteroid by measuring the solar-induced fluorescence spectrum in the soft x-ray regime (0.5-7.5 keV). A parametric model of the instrument is created to simulate its end-to-end operation, including x-ray propagation and absorption, detector noise processes, pixel read-out, signal quantization, and spectrum reconstruction. After validating the model against laboratory data, LSGA is used to identify multiple sets of top-level engineering requirements that meet the REXIS science objectives with regard to spectral resolution. These results are compared to the existing baseline requirement set, providing insights into the alternatives enabled by the model-based approach. Several additional strategies are presented to quantify and mediate requirement trades that may occur later in the development cycle due to science creep or engineering push-back. Overall, these methods provide a means of synthesizing and then evaluating top-level engineering requirements based on given science objectives. By doing so in a comprehensive and traceable manner, this approach clarifies the trade-offs between scientists and engineers that inevitably arise during the design of instrument systems.

Повний текст джерелаConcurrent engineering and similar techniques are on the rise in the industry. They are proven in research and in practice to strengthen the efficiency and quality in product development. Model-Based Definition is one of these techniques, in short it is concurrent engineering realized through an extensive and strategic use of CAD tools. Saab Dynamics is a producer of military products. They are now seeking to join the stronger players in this market in the use of the high quality strategy Model-Based Definition. Specifically, they seek to modernize their software and create a methodology where the software is used in a strategic manner. This thesis sought to analyze the implementation of a Model-Based Definition strategy in its initial stages of development to prepare the project owner Saab Dynamics to transition into using this type of strategy for future product development. This was researched through a case-study of another Saab subsidiary, Saab Electronic Defence Systems. Through literature studies the direction of the thesis was chosen to contain a large focus on managerial issues of Model-Based Definition, to expand the knowledge in the area from the highly technical perspective that is dominant today. The case-study itself was conducted by interviewing co-workers at Saab EDS, with prioritization towards a large diversity among the functions of co-workers to achieve a cross-functional perspective in the results. Analysis of the gathered information showed that even though the technical issues was not the main focus of the research, it was still a prominent factor in early Model-Based Definition implementation. However, arguably there are as much if not more that points to organisational and managerial factors being important for a succesful Model-Based Definition strategy. Pertaining to these factors, recommendations for Saab to solve issues encountered in the early implementation at Saab EDS include (but not limited to) the following: Create a strong team culture to accompany the cooperative strategy, planning the further progress to achieve short term benefits and new business opportunities to gain widespread support in the organization.

Las empresas a menudo desarrollan y mantienen colecciones de sistemas de software personalizados que comparten algunas características entre ellos, pero que también tienen otras características particulares. Conforme el número de características y el número de variantes de un producto crece, el mantenimiento del software se vuelve cada vez más complejo. Para hacer frente a esta situación la Comunidad de Ingeniería del Software basada en Modelos está abordando una actividad clave: la Localización de Fragmentos de Modelo. Esta actividad consiste en la identificación de elementos del modelo que son relevantes para un requisito, una característica o un bug. Durante los últimos años se han propuesto muchos enfoques para abordar la identificación de los elementos del modelo que corresponden a una funcionalidad en particular. Sin embargo, existe una carencia a la hora de cómo se reportan las medidas del espacio de búsqueda, así como las medidas de la solución a encontrar. El objetivo de nuestra tesis radica en proporcionar a la comunidad dedicada a la actividad de localización de fragmentos de modelo una serie de medidas (tamaño, volumen, densidad, multiplicidad y dispersión) para reportar los problemas de localización de fragmentos de modelo. El uso de estas novedosas medidas ayuda a los investigadores durante la creación de nuevos enfoques, así como la mejora de aquellos enfoques ya existentes. Mediante el uso de dos casos de estudio reales e industriales, esta tesis pone en valor la importancia de estas medidas para comparar resultados de diferentes enfoques de una manera precisa.

[EN] Nowadays, software exists in almost everything. Companies often develop and maintain a collection of custom-tailored software systems that share some common features but also support customer-specific ones. As the number of features and the number of product variants grows, software maintenance is becoming more and more complex. To keep pace with this situation, Model-Based Software Engineering Community is addressing a key-activity: Model Fragment Location (MFL). MFL aims at identifying model elements that are relevant to a requirement, feature, or bug. Many MFL approaches have been introduced in the last few years to address the identification of the model elements that correspond to a specific functionality. However, there is a lack of detail when the measurements about the search space (models) and the measurements about the solution to be found (model fragment) are reported. The goal of this thesis is to provide insights to MFL Research Community of how to improve the report of location problems. We propose using five measurements (size, volume, density, multiplicity, and dispersion) to report the location problems during MFL. The usage of these novel measurements support researchers during the creation of new MFL approaches and during the improvement of those existing ones. Using two different case studies, both real and industrial, we emphasize the importance of these measurements in order to compare results in a deeply way. The results of the research have been redacted and published in forums, conferences, and journals specialized in the topics and context of the research. This thesis is presented as compendium of articles according the regulations in Universitat Politècnica de València. This thesis document introduces the topics, context, and objectives of the research, presents the academic publications that have been published as a result of the work, and then discusses the outcomes of the investigation.

Повний текст джерелаThis thesis was carried out at Saab AB, Support & Service, in Tannefors, Linköping, and at the Department of Computer Science at Linköping University. One item in the quality work for complex industrial products, such as aircrafts, is to shift from two-dimensional design data to three-dimensional. Three-dimensional models have been around for years. The disadvantage of these models is that they could not carry any extra information, in addition to the information necessary for them to be plotted. The technology has moved on and now it is possible to store technical information in the models and do simulations that didn't work before. As the technical information is contained in the models, you can also use this information to the various publications that are printed. The purpose of this study is to analyze how the technical information flow between models and users, and also to propose examples of how technical publications for the Gripen NG may be in the future when using model-based design documents. Once all information is in the model, it is not needed to have as much staff employed for editing pictures or writing text. This will involve a financial gain, and after some time, it will also provide an additional financial benefit, because the users have learned how the product works and will be more efficient in using it than the current documents.

Повний текст джерелаIn the military aerospace industry, product data management in the product lifecycle, and development of logistics support are key areas that affect management of requirements and costs. The most recent strategy for these challenges is model-based definition (MBD). The discipline of technical communication has yet to explore and exploit the potential of MBD. Expected benefits include better ways of presenting illustrations and more efficient methodologies for production. This problem was investigated through a case study of the concept development of technical communication for Saab's fighter aircraft Gripen NG. The study focused on the illustrated parts catalog and its use. This work contributes with a model that describes four design levels for information systems, where presentation is the one in focus. In addition, comparable practices for management of MBD data were investigated in the case. The study found that the technical communication department is facing a transition from document-based management to development of information systems. Furthermore, three proposals for the next generation of parts catalogs are discussed. Two conclusions were reached. First, a lack of knowledge regarding the use of the parts catalog makes it difficult to assess new ways of presentation. And second, the improvements made in methodology and presentation in other MBD applications of the product life cycle are not immediately transferable to the parts catalog. Hence, suggestions for future research and work are presented.

Повний текст джерелаDetta examensarbete ämnar undersöka hur informationsöverföringen av produktrelaterad data sker i industrin för att kunna ge förbättringsförslag för Linköpings Universitets CAD- och ritteknikskurser. Detta för att kurserna bättre ska spegla industrins nuvarande och även framtida behov. Examensarbetet utfördes på avdelningen maskinkonstruktion vid Linköpings Universitet och är det avslutande momentet på författarnas civilingenjörsutbildning i maskinteknik.Till att börja med utfördes en litteraturstudie. Detta för att ge kunskap inom det aktuella området och vilka metoder som kan användas för datainsamling och analys. För att undersöka hur industrins arbetssätt ser ut utfördes en flerfallstudie på sju olika företag som bedriver produktutveckling tillsammans med egen produktion. Som datainsamlingsmetod valdes semistrukturerade intervjuer med anställda på de olika företagen.Analysen utfördes med hjälp av en adaption av ”affinity diagram technique” vilket delade upp företagens svar i kategorier i form av påståenden. Dessa jämfördes mellan företagen med hjälp av tabeller eftersom det var tydligt sätt att representera resultatet. För att ge en inblick i hur varje enskilt företag arbetar utarbetades även en deskriptiv sammanfattning av varje företag.För att kunna ge förbättringsförslag till universitetets CAD- och ritteknikskurser granskades några av de nuvarande kursernas kursplaner. Detta tillsammans med en informell intervju av de kursansvariga ledde till bättre insikt om hur kurserna är uppbyggda och vad målen med dem är. Insikten om vad kurserna innehåller i dagsläget tillsammans med analysen av de studerade företagens arbetssätt bidrog till att ett antal förbättringsförslag kunde föreslås.Det visade sig att graden av användande av modernare arbetssätt varierar kraftigt bland företagen. Detta gjorde det svårt att komma fram till ett enhetligt resultat som gällde för alla de studerade företagen. Däremot kunde ett antal slutsatser dras. Bland annat används fortfarande 2D-ritningar flitigt som ett informationsbärande dokument. En övergång till att enbart använda 3D-modellen som informationsbärare noterades endast på ett utav företagen men nämndes på ett par andra.Papperslöst arbete verkar vara på frammarsch trots att vissa specifika moment fortfarande utförs på papper. Det noterades även att digitala system används för lagring och hantering av produktrelaterad information hos alla de studerade företagen.Det som ansetts värt att implementera i universitets obligatoriska kurser efter genomförd studie är främst ökad användning av PDM/PLM-system, introduktion av 3D-måttsättning samt utnyttjande av 3D-modellen vid tillverkning.

"Estabilidade versus flexibilidade: a dicotomia necessária à inovação na gestão de recursos humanos em uma organização pública, estatal eestratégica como Bio-Manguinhos / Fiocruz." reponame:Repositório Institucional da FIOCRUZ, 2009. https://www.arca.fiocruz.br/handle/icict/2500.
Повний текст джерелаEste trabalho propõe analisar o fenômeno da terceirização desenvolvido ao longo das duas últimas décadas em Bio-Manguinhos. Trata-se de um estudo de caso realizado na unidade de produção de vacinas e reagentes para diagnóstico da Fundação Oswaldo Cruz. Inicialmente foi realizado um estudo de cenário, analisando a política de gestão do trabalho desenvolvida pelo Estado brasileiro para as instituições públicas. A seguir, a análise passou a verificar a inserção da Fiocruz nessas políticas, desde a sua criação e no decorrer de vigência de diferentes formas de contratação, alternando da extrema rigidez para a total flexibilidade sempre com foco na gestão do trabalho, e, como essas políticas se refletiram no desempenho de Bio-Manguinhos. Baseado no contexto da conformação do Estado e na análise do desempenho da unidade, o trabalho critica a falta de planejamento e de prospecção dessas políticas, que favoreça a inovação de processos, produtos e procedimentos e o desempenho pleno de uma unidade de produção de insumos para a saúde, tão necessários ao atendimento das necessidades da população brasileira. Critica também, a ausência de um modelo de Estado consolidado que sirva de arcabouço à formulação dessas políticas. Devido às fortes críticas dos órgãos de controle acerca da extrapolação dos limites da terceirização praticada nas últimas duas décadas e à falta de definição clara desses marcos legais, o trabalho apresenta uma metodologia baseada nas atribuições dos cargos do plano de carreiras da Fiocruz e culmina com a apresentação de uma matriz de atribuições passíveis de serem realizadas por contratação indireta. Conclui pela necessidade de convivência de dois quadros de trabalhadores: um permanente formado por servidores, estáveis e de carreira e outro flexível, executado por contratação indireta, de caráter eventual, temporário ou de apoio às atividades relacionadas à missão de Bio-Manguinhos. O trabalho ainda sugere a aplicação da mesma metodologia às demais unidades da Fiocruz e que a instituição afirme, frente aos órgãos de controle, quais atividades que ela precisa manter no quadro de servidores permanente e quais ela quer delegar a terceiros sem contudo, ferir a legislação vigente. Por fim, constata-se que a metodologia apresentada ameniza, mas não resolve o problema, dessa forma, recomenda-se à Fiocruz buscar mecanismos que altere o modelo de gestão pelo qual está submetida a fim de viabilizar as duas formas de incorporação de mão-de-obra.

As the bandwidth of Internet booms in recent years, consumers are accustomed to transmit image and video multimedia files through the network. Therefore, demands for optical devices including the digital video camera, web camera, and IP camera, increased rapidly in the past decade. In order to fulfill such demands, the notebook (NB) brand vendors, such as HP, Dell, Toshiba, Acer, and so on, have started to request their original design manufacturers (ODMs) to integrate the camera modules into NBs. Accordingly, the diffusion rate of NBs with the built-in camera module increased rapidly. Although the NBs equipped with a built-in camera module is a mega trend and becomes the basic feature in the NB market, most NB ODMs which survey built-in camera modules from specific vendors, do not realize exactly what features they really need due to insufficient domain knowledge. Consequently, the built-in camera module vendors are required to offer NB ODMs fundamental knowledge about the optical devices as well as proposed solutions which can fulfill the needs of ODM customers (i.e., the NB brand vendors) by either improving the designs or by adopting better technologies. What features can fulfill ODM customers’ wants as well as end-users’ needs from all aspects are always the most significant problem for the built-in camera module vendors. Built-in camera module vendors usually define the specifications based on their intuition since end-users of NBs usually are not familiar with the specification of modules. Traditional market research approaches cannot be leveraged. However, the module vendors usually define built-in camera modules based on their intuitions, which could be misleading. For above reasons, an appropriate research method for camera module vendors to resolve the specification definition problem can be very useful. Therefore, this research aims to resolve the above mentioned camera module feature definition problems by introducing a hybrid Multiple Criteria Decision Making (MCDM) based business to business (B to B) Lead User Method (LUM) consisting of the Decision Making Trial and Evaluation Laboratory Method (DEMATEL Method), the Analytic Network Process Method (ANP Method), and the VlseKriterijumska Optimizacija I Kompromisno Resenje Method (VIKOR Method). The evaluation criteria for a built-in camera module are first summarized by using the B to B LUM. After that, the DEMATEL method is introduced for deriving the structure of the decision problem. Furthermore, the ANP method is brought in to derive weights versus each criterion. Finally, the VIKOR method is launched to rank the alternatives and obtain the compromise solution. An empirical case based on a real-world NB built-in camera module design project is leveraged to demonstrate the feasibility of the proposed hybrid MCDM based B to B LUM. This verified hybrid MCDM based B to B LUM can be applied on specification definitions of products which improves what the traditional market research approaches cannot be leveraged.

With the development of Computer - aided Design (CAD), the product design evolved from manual mapping to today''s 3D modeling. While the 3D model is able to display the geometric characteristics directly, non-geometric features cannot show properly. Therefore, in the product design process, 3D model is the role of auxiliary design. With the development of Model Based Definition (MBD) technology, CAD software has developed adding the defined manufacturing and design information directly to the 3D model, changing the traditional manufacturing method. MBD model not only contains the geometric feature information also contains the information such as dimensions, tolerances and design information so that the 3D model will replace the traditional 2D drawings in the future and become the only tool for product design and manufacturing information delivery. This study is based on the concept of MBD technology to develop a slide design navigating system. Using software - Creo Parametric and network technology and its secondary development tools to store product information in the sample file. Using the parameters to change features for the required model, effectively reduce the product development process and time. Also, the study develop a function - dimension-labeled to simplify the labeling step which help users quickly build the size and tolerance. Through the study, the system can save 70% of the model building time and 50% of the dimension labeling time for slide product and achieve the purpose of MBD technology.

In the IT supply chain, Semiconductor distributors play a vital role and serve as the significant bridge between Semiconductor manufacturers and system manufacturers. Furthermore, professional Semiconductor distributors assist the manufacturers with sales and promotion, customer service and relationship management as well as marketing information providing. On the other side, distributors provide downstream system manufacturers with logistic management, warehousing, payment flow and technical support. However, the margins for Semiconductor distributors are very limited while the risks are comparatively higher due the very short product life cycles, market uncertainties, and price decline of inventories, e.g. Dynamic Random Access Memory (DRAM). For the past few years, many leading Semiconductor distributors expanded the business scale and product line by mergers and acquisitions to expand the scale and thus, achieve the scale of economies. So does the Semiconductor industry. In highly uncertain and complex and fast-moving high technology environments, business model innovation is more important than product innovation. Here, the managerial problem is how Semiconductor distributors can maximize their revenue and profits by business model innovation in the highly competitive environment. Thus, how to establish a decision support framework for business model innovations to enhance firms’ core competitiveness has already become one of the most critical issues for Semiconductor distributors. Thus, the business model innovation strategies selection problem is a typical multiple criteria decision-making (MCDM) problem which requires considering numerous factors while evaluating appropriate strategies. According to Chesbrough and Rosenbloom, this research classified the business model into six dimensions: (1) value proposition; (2) market segment; (3) value chain; (4) revenue mechanism; (5) value network; (6) competitive strategy. To resolve the above mentioned problem, this research intends to develop a decision making trial and evaluation laboratory (DEMATEL) based network process for deriving the strategies for business model innovation. First, the criteria and strategies for evaluating business model innovation are first summarized by literature review and then derivation of the exports opinion from Modified Delphi experts were invited to rank the influences of each criterion on other criteria. Then, the DEMATEL technique will be introduced to derive the key criteria for evaluating business model innovation strategies of Semiconductor distributors. The weights versus the factors will be derived by using the DEMATEL based network process (DNP). Finally, the performance scores versus the strategies will be evaluated by using the VIKOR. The empirical study based on experts’ opinions from the Semiconductor industry used for verifying the proposed MCDM framework. By and large, the empirical study indicates that competitive strategy and revenue mechanism were critical dimensions for business model innovation. In the meantime, build up barriers for competitors entry/ exit and generate revenue from licensing were selected as best strategies. The research results can serve as a basis of business model innovation strategy definition for executive officers.
