Implementing a new IT system often requires the enterprise to transform in order to maximally leverage the capabilities generated by the new system. The challenge in using IT as an enabler to change arises from the need to synergistically redesign processes, develop and implement a solution using internal talent and external suppliers, and establish adoption by users. Product Data Management (PDM) technology represents a substantial portion of large industry IT investment over the last decade. The ability to manage and deliver product data throughout the lifecycle has become increasingly important to the aerospace enterprise as products become more complex, cost and development cycles shorten, and customer, partner, and supplier relationships evolve. Currently, the aerospace community does not have capability to provide traceability from requirements and design through field maintenance. While initially an attempt to understand the application of PDM in product development, what emerged was a study in how PDM affects and enables lean enterprise transformation. The selection, development, and deployment of PDM solutions were studied in the aerospace industry in order to enable better implementation decisions in varying complex environments. Organizational, technical, and cultural factors were considered as they contribute to a PDM's effectiveness. .
(cont.) A current-state observation of nine aerospace company sites highlights the difficulty in reaching the technology's full potential to deliver customer value. Data show that PDMs are being used primarily to manage design engineering data and are not tightly integrated with other business systems. The data also show a distinct difference between prime and supplier companies' spending on and capability of their respective data management systems. While the value of PDM to product development includes better data quality, traceability and transparency, value to the enterprise is also found beyond the traditional role of PDM. Looking horizontally across the lifecycle and vertically through the hierarchical relationships, PDM provides opportunities for organizational and process change and stakeholder involvement, both important tenets for evolving into a lean enterprise. This conclusion is supported by both the site interviews and the two case studies

Texte intégralRésumé :
With the advent of digital imaging technology, the options available to consumers in consumer imaging have increased tremendously. From image capture through image processing and output, many options have emerged; however, the relative environmental impacts of these different options are not clear cut. Simplistically, one might say that the use of a digital camera has a lesser environmental burden than the use of a reloadable film camera because the image produced as a result of using the digital camera avoids chemicals in film developing. However, digital cameras require electronics and computers that need energy; and, energy production is one of the contributors to greenhouse gasses like CO2. Assessment of the environmental impacts of these different options can help provide feedback to decision makers and insights that will help reduce environmental impact through product system design.
One tool that has been used to relate environmental impacts with functions provide to consumers through products or services is Life Cycle Assessment (LCA). LCA, which has been standardized by the International Standards Organization (ISO) in ISO14000, is used here to evaluate both traditional film and digital imaging systems. Data from publicly available databases and both external and internal Eastman Kodak Company studies were utilized to develop LCA modules for the different processes involved. Product and service business models are explored for both technologies through ten different imaging and output scenarios. The functional unit used is the capture, processing and output of one 4 x6 image. Four impact categories (energy use, greenhouse emission, water use and waste generation) across four life cycle phases (upstream, distribution, use, and end of life) are explored for the ten scenarios.
LCA is also evaluated as a tool to help facilitate strategic level environmental performance issues with both new and established business activities. Sensitivity analysis is also performed to evaluate the impact of assumptions made in the course of the assessment and comments are made regarding the effectiveness of LCA for strategic assessment and product service strategies in lowering environmental impact.
Results indicate that the lowest impact scenarios are Digital Capture to LCD Display for Greenhouse Emissions and Energy Use and Film Capture to Wholesale Print for Water Use and Waste Generation. Highest impacts were seen for Greenhouse Emissions in the Film Capture to Retail Print scenario. In the Energy Use and Water Use category, the Digital Capture to CRT Computer Display was the highest scenario. For Waste Generation, the Digital Capture to Inkjet Print was the highest impact scenario.

Texte intégralRésumé :
Product Lifecycle Management (PLM) is a holistic approach for managing product information throughout its life cycle. It integrates different concepts that have emerged due to changes in the manufacturing process as a result of globalization, increased competition, demand for more innovative products, and other reasons. These changes have leaded to a shift from a model with a single-location for product development to a model in which a complex network of specialized companies collaborate. This global collaborative PLM implies that companies from different parts of the world work together and must share information; hence the underlying PLM system is required to facilitate data management throughout this collaborative process. In addition, it is also necessary to address the challenges due to the new model being a distributed activity, as today this PLM system is a specialized distributed system. Maintaining data consistency can be challenging because collaborators can use heterogeneous PLM systems together with their own databases. The later cannot be shared due to the risks of exposing their knowledge base and business processes. Another consideration in global collaboration is that data is transmitted to remote locations. As a result network latency can be large; this can cause problems particularly when large files are exchanged, such as may be the case for CAD design models. This thesis proposes a solution enabling a global PLM which addresses the challenges described above. The approach consists of connecting collaborators’ nodes in a network that is constructed by grouping them with respect to intra-site latency. Each group implements a coordination mechanism based on the election of a node which is subsequently in charge of coordinating data access. The groups communicate via a publish-subscribe communication pattern, publishing and subscribing to events related to the resources being shared. The integration of the solution is through a Service-oriented Architecture (SOA) implementing web services that can be consumed by a PLM system. A prototype has been implemented and its applicability is analysed by evaluating its functionality in a collaborative scenario based on the Aras Innovator PLM platform. The evaluation was made by simulating the solution proposed and comparing it with a centralized approach. The results particularly showed that the proposed solution could reduce the intra-latency compared to a centralized approach if the collaborators are organized in collaborative groups, that exchange most of the information inside the group rather than intergroup.Product Lifecycle Management (PLM) är en helhetssyn som hanterar produktinformation under deras hela livscykel. PLM integrerar olika koncept som har dykt upp på grund av förändringar i tillverkningsprocessen som en följd av globalisering, stor konkurrens, efterfrågan på mer innovativa produkter, och andra orsaker. Dessa förändringar har blyad till en övergång från en modell med en enda plats för produktutveckling till en modell där ett komplext nätverk av specialiserade företag samarbetar. Detta globala samarbete inom PLM innebär att företag från olika delar av världen arbetar tillsammans och delar information. Det underliggande PLM-systemet krävs att underlätta datahantering hela denna samverkande process. Dessutom är det också nödvändigt att hantera utmaningar beroende på den nya distribuerade modellen som gör PLM -system blir specialiserade distribuerade system. Underhålla uppgifter konsekvens kan vara en utmaning eftersom kollaboratörer kan använda heterogena PLM-system med sina egna databaser som inte kan delas på grund av riskerna för att utsätta sin kunskapsbas och affärsprocesser . En annan faktor i den globala samarbetet är att data överförs till avlägsna platser . Som ett resultat nätverksfördröjningen kan vara stora, vilket kan orsaka problem speciellt när stora filer utbyts, exempelvis CAD-modeller. Detta masterarbete föreslår en lösning för att möjliggöra en global PLM som tar upp de utmaningar som beskrivs ovan. Tillvägagångssättet består av anslutande kollaboratörer noder i ett nätverk som konstrueras genom att gruppera dem i förhållande till intra-site latens. Varje grupp genomför en mekanism för samordning grundas på valet av en nod som därefter ansvarar för samordningen av dataåtkomst. Grupperna kommunicerar via en publiceraprenumerera kommunikationen mönster av att publicera och prenumerera på händelser relaterade till de resurser som delas. Integrationen av lösningen är genom en Service-Oriented Architecture (SOA) genomföra webbtjänster som kan konsumeras av ett PLM-system. En prototyp har genomförts och dess användbarhet analyseras genom att utvärdera dess funktionalitet i en kollaborativ scenario baserat på Aras Innovator PLM-plattform. Resultaten visade att den föreslagna lösningen skulle kunna minska intra-latens jämfört med en centraliserad strategi om kollaboratörer är organiserade i kollaborativa grupper, varje grupp är ansvarig för utformningen ett delsystem av produkten och därmed utbyta mesta av informationen inom gruppen snarare än inter-gruppen.

Texte intégralRésumé :
Le système PLM est l’un des outils stratégiques de l’entreprise. Ces systèmes sont sujets à des changements récurrents dans l’entreprise. Les évolutions organisationnelles, le changement de l’offre produit ou encore le remplacement de logiciels PLM peuvent déclencher l’évolution du système d’information PLM. Une des structures les plus importantes dans les systèmes PLM est le modèle du produit, autour duquel s’articule les informations et processus. C’est autour du modèle produit que se concentrent nos recherches. Les causes d’évolution des modèles produits sont des éléments signifiants qui différencient les étapes de la démarche à suivre. Les méthodes d’IDM sont utilisées afin de formaliser la transformation des modèles. En plus, cette démarche bénéfice d’un cadre de similarité spécialement développé pour la configuration de produit. Un exemple industriel est illustré et résolu en appliquant cette démarche. Il s’agit de l’évolution d’un système gérant les modèles spécifiques de produit vers un système qui est capable de construire et d’utiliser les modèles génériques de produit. Un outil informatique support à nos travaux est développé dans le cadre d'EclipsePLM systems are among the strategic components of enterprise’s information system architecture. These systems undergo frequent evolutions of enterprise. Organizational evolution or product offer variation as well as PLM application replacement may launch PLM systems’ evolution.One of the important structures in PLM systems is the product configuration, which organize and structure all product’s information and processes. Our research activities concern product model evolution. Reasons of product model evolution specify the appropriate methodology and necessary steps in order to handle it. MDE methods are used to formalize the model transformation process.Moreover, our methodology contains a specific similarity framework dedicated to product configuration. An industrial example was illustrated and resolved by this methodology. The problematic of this example is the migration of a system which manage only specific product configuration to a new system that is capable to construct and use generic models of product

Texte intégralRésumé :
Approved for public release; distribution is unlimitedA 2010 review of 96 defense acquisition programs showed average delivery rates are 22 months behind schedule and the cumulative cost growth exceeded $296 billion. With budget cuts looming, a small window of opportunity exists to enact reforms improving the health and solvency of the defense acquisition portfolio. First, we must leverage the technology investments made into collaborative software suites such as product lifecycle management (PLM) to align the requirements, design, engineering, logistics, maintenance, and operational data environments into one comprehensive activity. Implementing a PLM strategy will present cost-saving opportunities through faster information access, improved data reuse, social networking, and virtual collaboration and testing. PLM systems have the ability to capture and organize vast amounts of data. Because through human interaction data becomes knowledge, lean product design is a philosophy that can change how we think, learn, use, and build up on that knowledge. By going beyond merely attacking waste by finding a balance between waste reduction and value addition, total ownership costs can be reduced drastically. These reforms have the ability to fundamentally change how we design, build, and maintain the fleet, making the defense portfolio solvent and thus continuing to fulfill the needs of the warfighter.

Texte intégralRésumé :
Product Lifecycle Management (PLM) systems are used by thousands of engineering companies world wide. Improving these systems will have a drastic and global effect. One possible improvement is to integrate synchronous collaborative applications with PLM systems. These applications allow multiple people to work on a single digital object simultaneously. They have already been shown to reduce the time a task requires. Using these applications to complete a project will reduce the project time. However, simply including synchronous collaborative applications within a PLM system ignores powerful benefits that could provide further time-saving benefits. The integration must allow improved awareness at the project level, so that users can mediate their own actions.This thesis presents a method for such an integration. It also presents a prototype which implements that method. Testing was carried out using this prototype. As hypothesized, including synchronous collaborative applications shortened the overall project time. In addition, providing awareness information and allowing users to mediate themselves further shortened project times and reduced variation in those times. Proper integration should therefore provide awareness at the project level and allow users to mediate themselves to some extent.

Texte intégralRésumé :
Technical debt is a well known term within software development, but has not yet been implemented outside of software development. Because of this, there is no knowledge whether that is possible or not. This thesis investigates how technical debt can be extended to and be identified within a software system for handling Product Lifecycle Management. The purpose of the thesis is to present a prototype, called the ITS-prototype, which shows that it is possible to identify technical debt within Product Lifecycle Management. The thesis has qualitative characteristics and were conducted as a case study. In order to verify that the implementation is correct, two evaluation criterias were established. The first criteria, measuring the degree of coverage, saying that the ITS-prototype should be able to identify 100% of the technical debt defined by each rule. The second criteria consists of an interview with a technical expert on Product Lifecycle Management where the prototype's underlying method is evaluated. The ITS-prototype together with the results of the evaluation shows that technical debt is possible to be implemented and identified in a software system for handling Product Lifecycle Management. The rule-driven implementation that is used, has shown effective and the authors suggests that the development of the ITS-prototype continues in order to better use conveniences that exist within a Product Lifecycle Management-system.Teknisk skuld är ett vedertaget begrepp inom mjukvaruutveckling men har ännu inte implementerats utanför mjukvara. Således finns det ingen kunskap om huruvida det är praktiskt möjligt att göra detta eller inte. I detta arbete undersöktes om konceptet teknisk skuld kan implementeras i ett mjukvarusystem för hantering av Product Lifecycle Management. Syftet med arbetet är att visa att teknisk skuld kan implementeras inom Product Lifecycle Management genom att presentera en prototyp för identifiering av teknisk skuld inom Product Lifecycle Management, kallad ITS-prototypen. Arbetet är av kvalitativ karaktär och genomfördes som en fallstudie. För att verifiera att implementationen är korrekt upprättades två utvärderingskriterier. Det första mäter prototypens täckningsgrad och säger att ITS-prototypen ska kunna identifiera 100% teknisk skuld definierad av varje regel. Det andra kriteriet består av en utvärderingsintervju med en teknisk expert på Product Lifecycle Management, där prototypens underliggande metod utvärderas. ITS-prototypen tillsammans med resultaten av utvärderingen visar att teknisk skuld är möjlig att implementera i ett mjukvarusystem för hantering av Product Lifecycle Management. Den regeldrivna implementation som använts i ITS-prototypen är effektiv och författarna föreslår att utvecklandet av prototypen fortsätter för att bättre kunna nyttja fördelar i ett PLM-system.

Texte intégralRésumé :
Enterprises have deployed Legacy Systems to carry out the mission critical business processes within its current IT infrastructure. Legacy Systems being primary assets of the organization, the key challenge of such systems is reusing and leveraging the valuable business logic that resides within these applications. Despite the significant business value provided by the legacy systems, to conform to the changing business needs demands transition of these legacy systems towards modern architecture. Service Oriented Architecture (SOA) an architectural approach helps enterprises in reuse of existing assets as well as addressing increasing business demands. An effective way of migration of legacy systems to SOA is through exposing their functionality as services. SOA approach constitutes various advantages that employ standard, platform independent, well-defined service interfaces, which is suitable for realizing enterprise application integration with other systems. There has been a growing interest in the legacy system to SOA modernization among the academic and industrial research community. The methods proposed by this community primarily focus on how the critical business logic of the legacy system is migrated i.e. how to convert the functionality of existing systems into services to gain the benefits of SOA. This research focuses on investigating the feasibility of providing web service access to the data stored in legacy vPLM system. It also involves developing a prototype taking application integration best practices, Scania IT SOA guidelines and metrics such as reusability, performance and security into account.

Texte intégralRésumé :
Context. In practice, software projects frequently fail in many fields, which causes the huge loss for the human being. Assumption faults are recognized as a main reason for the software project failures. As the world is changing fast, environment assumptions of software can be easily wrong. The daily assumption-related activities show not enough effectiveness and efficiency to deal with assumption faults. For example, no documenting of key assumptions, inappropriate assumption validation, lack of knowledge. In research, there is no empirical research about assumption management practice. Two assumption management frameworks were outlined. They both support the assumption formulation and assumption management. The formal assumption management framework provides an assumption-component mapping function to analyze assumption failures. Objectives. Our goal is figuring out how development team members handle environment assumptions today in practice and how they might handle them better tomorrow. To be specific, I test the applicability of the so far theoretical assumption management frameworks and investigate the assumption type, assumption formulation and assumption management in practical software development Methods. An interview-based survey was implemented with 6 product managers from Chinese software companies. They have rich experiences on assumption management and software development. I used directed content analysis to analyze the qualitative data. The result of the research is intended to be a static validation of the assumption management frameworks. Results. Interviewees consider that the assumption-component mapping function of the formal assumption management framework is useful in making decisions and analyzing the problems. However, using these frameworks takes too much effort. The functions of frameworks are covered by the development team members and the existing tools. Assumptions tend to be discovered when they frequently change and are important to the requirements. The main assumption types are user habit assumptions and quality attribute assumptions, which are both requirement assumptions. The user habit assumptions consist of name, description and value, while the quality attribute assumption formulation is name and value. The major assumption treatment activities are figuring out the value of assumptions, assumption monitoring, assumption validation and handling assumption failures. Assumption failures result in the loss of users and benefits. Assumption failures are always caused by the poor ability and experience of development team members. Conclusion. I create an assumption management model based on my result, and find out the advantages and disadvantages of the formal assumption management framework and semi-formal assumption management framework. The research could help improve the efficiency and effectiveness of assumption management practice. Also. The research can be treated as the starting point to study assumption management practice deeper.

Texte intégralRésumé :
Nos travaux de thèse contribuent au domaine de la Gestion du Cycle de Vie des Produits (PLM : Product Lifecycle Management) selon deux objectifs : l'un concerne plus particulièrement l'analyse et l'état de l'art des concepts liés au domaine du PLM alors que le second va chercher à tirer avantage de ces concepts pour la formalisation d'un metamodèle adapté à la Traçabilité des produits tout au long de leur cycle de vie. La gestion intégrée de toute information relative au produit et à sa production est une des questions majeure de l'industrie. Une des réponses à cette question, actuellement d'actualité, concerne un paradigme naissant, défini par le vocable de Gestion du Cycle de Vie des Produits (PLM : Product Life Cycle Management). Dans ce contexte, l'une des problématiques concerne la traçabilité des produits tout au long de leur cycle de vie qui induit ainsi une nécessaire interopérabilité de l'information ainsi que des efforts de standardisation. Afin d'assurer ces échanges d'information, notre contribution, basés sur la situation actuelle des systèmes d'information d'entreprise (qui manipulent l'information sur les produits), doit aboutir à la définition d'une vue holonique d'un modèle conceptuel orienté produit d'un système de production, formalisant la structure du système d'information associé aux données de traçabilité des produitsThe thesis contributes to the area of PLM (Product Lifecycle Management) as a two-layer topic: the first deals with a definition of the boundaries of what is considered as PLM in the market, while, in a complementary way, the second deals with the definition of a reference metamodel for product management and traceability along the product lifecycle. Product and production management have become complicated processes where more problems are overlapping each other's. Product development might ever more take into account improved customers' tastes and requests in a shorter time-to-market. This way, the product lifecycle and its related management are becoming unavoidable key aspects, creating such a “product centric” (or product-driven) problem. The integrated management of all the information regarding the “product” and its production is one of the related questions. One of the main issues concerning with the product management in a wider perspective (along a defined lifecycle), deals with the traceability of the product. The problem of information exchange could easily arise and further standardization efforts will be needed, so establishing a kind of barriers to the diffusion of the same holonic traceability. In order to reduce these further barriers, but ever more in order to improve the currently definition and the study of Holonic product traceability, we are looking to the current situation of enterprise information systems (where product information are resident) and trying to elaborate it in an holonic view, creating a conceptual HMS product-oriented architecture

Texte intégralRésumé :
In an ever changing market that expands continuously and where innovations cycles become shorter, there is an important increase of the renewal frequency of the electrical and electronic equipment (EEE) and vehicles. This makes the manufacture of EEE and vehicles a fast-growing source of waste in terms of used products. The immense amount of information generated by all these technological products which are currently in the market must be managed throughout the whole life cycle of the products. The problem is to provide information about the technological product’s reusability in the recycling process given the colossal complexity of many products and the lifespan of operation. This includes instructions about the components qualifications as elements in a new product. Technologies such as augmented reality (AR) combined with product lifecycle management (PLM) systems can provide the platform for an information system that provides the necessary information and support for the decommissioning process of EEE and vehicles at the end of their life cycle. The present project describes the framework of integration between AR and PLM with the purpose of recycling a technological product at the end of its life cycle. The proposed method of integration could be considered to constitute both an innovation and a possible improvement if compared with the current approach. It is believed that the development of a method that addresses the issue of integration between AR and PLM could provide with a secure, efficient management of stored data related to various products and their properties related to the recycling process at the end-of-life of the product. The result of this approach is an AR-PLM system architecture which assists the circular economy’s recycling process by the use of visual information superimposed on the physical technological equipment.

Texte intégralRésumé :
Le travail de recherche présenté dans ce mémoire s'intéresse aux problèmes d'interopérabilité dans le domaine du Product Lifecycle Management (PLM) et vise à proposer une méthodologie capable d'y remédier. Nous définissons l'objectif stratégique du PLM comme la maîtrise de la complexité qui caractérise le développement et le suivi des produits. Dans ce cadre, l'objectif de l'interopérabilité est le contrôle des interactions entre constituants de ce système complexe PLM. Nous montrons que cet objectif est atteint si on assure la continuité et la conservation du flux sémantique qui circule dans le système. Notre étude est restreinte aux seuls domaines de la conception et de la production, mais a l'ambition de pouvoir s'appliquer à d'autres domaines. La continuité du flux sémantique est assurée par une architecture que nous avons baptisée « médiation multi-échelle orientée services ». Le cœur de cette architecture, le médiateur, se charge d'orienter les flux sémantiques vers les systèmes concernés, et met en correspondance sémantique les informations échangées en s'appuyant sur un méta-modèle d'unification. Nous montrons que pour assurer la robustesse, la flexibilité et l'agilité du système ainsi constitué, il faut privilégier le choix d'un méta-modèle standard générique et extensible. A cet effet, nous proposons une cartographie du standard STEP permettant de choisir le méta-modèle pertinent. Nous illustrons le choix et la définition de ce méta-modèle dans le cas de deux problèmes d'interopérabilité des domaines de la conception et de la production : l'interopérabilité CAO/PDM et l'interopérabilité PDM/ERP. Nous expliquons notre démarche dans la mise en œuvre de la norme PLCS. Par ailleurs, nous introduisons un modèle d'annotations sémantiques du produit qui permet de reconstruire des vues multiples correspondant à différents besoins métiers. Un ensemble de démonstrateurs permet de valider nos propositions et nos résultats.

Texte intégralRésumé :
Ces dernières années, les produits dits « intelligents » ont été introduits dans de nombreux domaines tels que l’industrie, la santé et le transport. Ces produits sont devenus sources d’informations durant leurs phases d’utilisations. L’obtention de ces informations constitue un avantage certain pour les différents acteurs intervenant dans le cycle de vie du produit. Le nombre important d’acteurs et la diversité des besoins exprimés rendent complexe la mise en œuvre des chaines informationnelles entre produit et acteurs en phase d’utilisation, ainsi que la génération de flux d’informations vers les phases amont et aval du cycle de vie. S’appuyant notamment sur les concepts développés par la communauté CL2M (Closed Loop Lifecycle Management), cette thèse propose une architecture « générique » permettant de modéliser les chaines informationnelles et les processus décisionnels associés à un produit lors de sa phase d’utilisation. Cette architecture repose sur l’utilisation de fonctions secondaires associées au produit ainsi que des concepts holoniques permettant de prendre en compte le produit, sa décomposition en sous-produits et son contexte (i.e. environnement, tâche et utilisateur(s)). L’architecture s’inspire également de la typologie de Rasmussen pour caractériser différents niveaux cognitifs au sein des processus décisionnels. Un guide méthodologique est également proposé pour aider au déploiement de telles chaines informationnelles et décisionnelles. L’architecture proposée est mise en œuvre et validée dans le cadre d’une plateforme POC (Proof of Concept). Tant le modèle que le guide sont évalués au travers de scénarios représentatifs de l’utilisation d’un connecteur « intelligent » de test industriel dans le domaine de l’automobileIn recent years, “smart products” have been introduced in many areas such as industry, health and transportation systems. These products are sources of information during their use phases. Collecting, processing this information is a definite advantage to aid the various stakeholders involved in the product lifecycle to improve the value chain. The large number of stakeholders and the diversity of their needs make it difficult to implement the information chains between the product and the stakeholders in the use phase (as well as the generation of information flows towards the upstream and downstream phases of the life cycle). Based on the concepts developed by the Closed Loop Lifecycle Management (CL2M) community, this thesis proposes a model of generic architecture for modeling the information chains and decision-making processes associated with a product during its use phase. The proposed model relies on secondary functions associated with the product, on holonic concepts, on product context (i.e. environment, task and user(s)) and on decision-making processes. This last point is inspired on Rasmussen's typology to characterize different cognitive levels. A methodological guide is also proposed helping to transform the model into operational architecture implementing information chains. The proposed architecture is implemented and validated as part of a POC (Proof of Concept) platform. Both the model and the guide are evaluated through scenarios representative of the use of a "smart" industrial test connector in the automotive field

Texte intégralRésumé :
Product lifecycles are complex heterogeneous systems. Applying control methods to lifecycles requires significant human capital. Additionally, measuring lifecycles relies primarily on domain expertise and estimates. Presented in this dissertation is a way to semantically represent a product lifecycle as a cyber-physical system for enabling the application of control methods to the lifecycle. Control requires a model and no models exist currently that integrate each phase of lifecycles. The contribution is an integration framework that brings all phases and systems of a lifecycle together. First presented is a conceptual framework and technology innovation. Next, linking product lifecycle data dynamical is described and then how that linked data could be certified and traced for trustworthiness. After that, discussion is focused how the trusted linked data could be combined with machine learning to drive applications throughout the product lifecycle. Last, a case study is provided that integrates the framework and technology. Integrating all of this would enable efficient and effective measurements of the lifecycle to support prognostic and diagnostic control of that lifecycle and related decisions.Ph. D.
The manufacturing sector is on a precipice to disruptive change that will signifcantly alter the way industrial organizations think, communicate, and interact. Industry has been chasing the dream of integrating and linking data across the product lifecycle and enterprises for decades. However, inexpensive and easy to implement technologies to integrate the people, processes, and things across various enterprises are still not available to the entire value stream. Industry needs technologies that use cyber-physical infrastructures efectively and efciently to collect and analyze data and information across an enterprise instead of a single domain of expertise. Meeting key technical needs would save over $100 billion annually in emerging advanced manufacturing sectors in the US. By enabling a systems-thinking approach, signifcant economic opportunities can be achieved through an industrial shift from paper-based processes to a digitally enabled model-based enterprise via the digital thread. The novel contribution of this dissertation is a verifed and validated integration framework, using trusted linked-data, that brings all phases and systems of the product lifecycle together. A technology agnostic approach was pursued for dynamically generating links. A demonstration is presented as a reference implementation using currently available technology. Requirements, models, and policies were explored for enabling product-data trustworthiness. All methods were developed around open, consensus-based standards to increase the likelihood of scalability. The expected outcome of this work is efcient and efective measurements of the lifecycle to support data-driven methods, specifcally related to knowledge building, decision support, requirements management, and control of the entire product lifecycle.

Texte intégralRésumé :
Natural raw materials are consumed at a rapid rate due to the ever-growing population and the endless pursuance of higher living standard of human kind, which alerts the manufacturing industry that resource crisis would come soon if no proactive actions are taken. Rapid manufacturing and consuming of products also brings about the serious environmental problems, e.g. over mining leads to surface water and groundwater pollution, energy consumption emits huge greenhouse gases, countless solid wastes threats human’s health and the sustainable use of land. Manufacturing industry is faced with the dilemma of either to keep the economic growth to meet the increasing society demand by immolating the earth and eco-system, or to save the earth by sacrificing economic growth. However, besides those two alternatives, we could rethink about developing innovative sustainable manufacturing strategies to find the balance point of environmental, economic and social sustainability. In this thesis, Multiple Lifecycle Product (MLP) is put forward as a solution towards sustainable manufacturing. It aims to shift the current open loop manufacturing model i.e. “take-make-dispose” to a seamless closed loop manufacturing model, which enables a product to have multiple lifecycles for maximizing the utilization of raw material, minimizing the consumption of energy and recapture the utmost value-added i.e. inputs in terms of labor, plant, equipment, etc. Resource Conservative Manufacturing (ResCoM) is such a closed loop manufacturing system developedbased on MLP concept, which implements MLP through a series of meticulous and collaborative works of product design, business model, closed loop supply chain and remanufacturing. Numberless information will be generated from the collaborative work during the implementation of MLP, and in each lifecycle of a MLP a wide range of product-related information has to be archived properly. Therefore, this research work starts to develop a new PLM for MLP, also called ResCoM PLM which will be one of the most powerful support tools for information management and decision-making of MLP manufacturing. As the beginning of ResCoM PLM research, this thesis targets to create a framework and foundation of ResCoM PLM research. Concepts and terminologies in the area of PLM for MLP are established systematically, and the ambiguous or overlapped concepts and terms presented in the state-of-the-art will be compared and explained. IDEF0 information model of MLP is createdby investigating the essential activities of implementing MLP, i.e. product design, business design, closed loop supply chain management and remanufacturing/manufacturing. Through elaborating the mutual interdependence, interactions, feedback and causalities among the essential activities and revealing the information and material flows of MLP manufacturing helps the readers to have deep understanding of MLP manufacturing and identify the issues of ResCoM PLM research.

Texte intégralRésumé :
In order to gain competitive advantages in markets, companies have provided a variety of customized products to satisfy customer-specific requirements, leading to not only a large amount of product data but also high cost, long lead-time and complexity of quality control. Efficient product data management throughout the product lifecycle has become increasingly crucial, of which product structure management is regarded as the most important constituent. The study took ABB Mine Hoist system as a case to investigate how to construct a generic product structure model fit for engineer-to-order system offerings with the consideration of their sales-delivery product lifecycle. The aim of the model is to facilitate the product-related information sharing and reuse across a company, and the integration of different business operations throughout the entire product lifecycle as well. Based on the current situation analysis of product data management on ABB Mine Hoist, three major issues were identified which need to be addressed in the formulation of a generic structure model: namely the integration of requirements of multiple disciplines; the consistency of product information throughout the product lifecycle; and the constant update of product repository. Through illustrating the formulation of ABB Mine Hoist generic structure model, the method of how to construct a generic product structure model for engineer-to-order system product was presented. The model was achieved by applying the framework of the step-based product model and was regarded as a result of integrating domain-specific requirements. The adaptive generic product structure model was then employed to display the role of this generic model in the different phases of a sales-delivery lifecycle. The model could serve as a “master concept” to transfer common product information in the product lifecycle. It’s expected to benefit the business of engineer-to-order system product through improving the integration of different disciplines, enhancing information exchange and reuse. It could also provide an abstract and conceptual basis for potential product repository to reinforce data consistency and completeness.

Texte intégralRésumé :
One of the most significant changes in the evolution of modern business management is that organizations no longer compete as individual entities in the market, but as interlocking supply chains. Markets are no longer simply trading desks but dynamic ecosystems where people, organizations and the environment interact. Products and associated materials and resources are links that bridge supply chains from upstream (sourcing and manufacturing) to downstream (delivering and consuming). The lifecycle of a product plays a critical role in supply chains. Supply chains may be composed by, designed around, and modified for products. Product-related issues greatly impact supply chains. Existing studies have advanced product management and product lifecycle management literature through dimensions of product innovation, product growth, product line extensions, product efficiencies, and product acquisition. Product deletion, rationalization, or reduction research is limited but is a critical issue for many reasons. Sustainability is an important reason for this managerial decision. This study, grounded from multiple literature streams in both marketing and supply chain fields, identified relations and propositions to form a firm-level analysis on the role of supply chains in organizational product deletion decisions. Interviews, observational and archival data from international companies (i.e.: Australia, China, India, and Iran) contributed to the empirical support as case studies through a grounded theory approach. Bayesian analysis, an underused empirical analysis tool, was utilized to provide insights into this underdeveloped research stream; and its relationship to qualitative research enhances broader methodological understanding. Gibbs sampler and reversible jump Markov chain Monte Carlo (MCMC) simulation were used for Bayesian analysis based on collected data. The integrative findings are exploratory but provide insights for a number of research propositions.

Texte intégralRésumé :
This thesis seeks to improve the workflow in the product development process when using the Product Lifecycle Management (PLM) system PLM2020, incorporated at Siemens Energy. Focus is on three problem cases that emerge when working with Computer Aided Engineering (CAE) data during the development process. Apart from solving these problems, a current situation analysis was conducted, and possible solutions of these problems were investigated on how they affect the lead time in the product development process. The problems consist of exploration of an unused function and solving of two problematic situations that can occur while using PLM2020 during development work. A case study was established to investigate the problems, using participatory observations and interviews. The interviews established the current situation of Siemens work methodology to handle these situations and how PLM2020 is used. During the observations, the problems were attempted to be solved using an arbitrary Computer Aided Design (CAD) model while exploring different functions in a sandbox environment. During the interviews, it was discovered that there exist different ways of working in PLM2020 and that some approaches nullifies the benefits of using a PLM system. The participatory observations revealed that that there exist functions in the PLM system that solves the problems encountered. A set of proposed solutions are presented to Siemens

The management of information is one of the key aspects within a successful andefficient product development process, particularly regarding complex products.Scania CV AB is at the moment developing a new IT-system, OAS, which aims tomanage the company’s product data. With this as a background, the purpose of thismaster thesis is to identify the cross-functional user needs within Scania’s organizationconcerning product data and the management around it. To fulfill the purpose, an empirical study consisting of 40 personal interviews with 50representatives from different functions within Scania’s organization was carriedthrough. The empirical data was then analyzed focusing on identifying thecross-functional needs and issues. The study points out that there is a big potential regarding improvement among themanagement of product data. For example, a lot of time is spent by the users to findthe requested information and to copy data manually from one IT-system to another.The most important findings, in terms of cross-functional user needs within Scania’sorganization, are the integration of Scania’s many IT-system and to make informationmore accessible. Further needs are regarding the ability to follow a product’s entirelifecycle, better support for the user’s understanding of the complex product, anenhanced management of Engineering Change Orders and a better supportconcerning the product structure.

Texte intégralRésumé :
Consciente que l’unité de compétitivité n’est plus l’entreprise mais toute la chaîne logistique contribuant à la réalisation du produit, les efforts consentis par l’entreprise se matérialisent, d’une part, par la volonté de maîtriser au mieux les activités de conception des produits et d’autre part, par la construction de collaborations entre tous les acteurs de la chaîne logistique participant au cycle de vie du produit. Cela a conduit à l’émergence d’une gestion collaborative du cycle de vie du produit appelée communément PLM. L’objet de cette thèse consiste à définir une démarche méthodologique pour répondre à la problématique suivante : Comment le PLM pourra t-il participer à l’optimisation de la chaîne logistique ? Nous adoptons, dans cette thèse, une approche hybride combinant PLM et modèles mathématiques pour optimiser les décisions de conception simultanée du produit et de sa chaîne logistique. Nous proposons des modèles conceptuels pour résoudre de manière formelle le compromis entre PLM et modèles mathématiques pour une optimisation de la chaîne logistique. Contrairement aux approches classiques centralisées utilisées pour traiter le problème intégré de conception du produit et de sa chaîne logistique et qui engendrent des modèles mathématiques compliqués, nous adoptons une démarche couplant des décisions centralisées quand il s’agit d’intégrer les contraintes des différents maillons de la chaîne logistique et une approche décentralisée quand il s’agit d’optimiser localement chaque maillon de la chaîne. Le mode décentralisé réduit la complexité de résolution des modèles mathématiques et permet à la chaîne logistique de répondre rapidement à l’évolution des conditions locales de chaque maillon. Le PLM joue le rôle d’intégrateur. En effet, le regroupement centralisé des informations par le PLM permet de prendre en considération la dépendance entre les maillons améliorant ainsi les résultats obtenus par optimisation localeAIt is recognized that competition is shifting from “firm versus firm” perspective to “supply chain versus supply chain” perspective. Therefore, the ability to optimize the supply chain is becoming the critical issue for companies to win the competitive advantage. Furthermore, all members of a given supply chain must work together to respond to the changes of market demand rapidly. In the actual context, enterprises not only must enhance their relationships with each others, but also need to integrate their business processes through product life cycle activities. This has led to the emergence of a collaborative product lifecycle management commonly known as PLM. The objective of this thesis is to define a methodological approach which answers to the following problematic: How can PLM contribute to supply chain optimization ? We adopt, in this thesis, a hybrid approach combining PLM and mathematical models to optimize decisions for simultaneous design of the product and its supply chain. We propose conceptual models to solve formally the compromise between PLM and mathematical models for supply chain optimization. Unlike traditional centralized approaches used to treat the problem of integrated design of the product and its supply chain which generate complex mathematical models, we adopt an approach combining centralized decisions while integrating the constraints of the different supply chain partners during the product design and decentralized decisions when it comes to locally optimize each supply chain partner. The decentralized approach reduces the complexity of solving mathematical models and allows the supply chain to respond quickly to the evolution of local conditions of each partner. PLM will assure the integration of the different supply chain partners. Indeed, the information centralization by the PLM enables to take into consideration the dependence between these partners, improving therefore local optimization results

Zara introduces 10,000 new designs every year and distributes 5.2 million clothing articles per week to a network of over 1925 stores in more than 86 countries. Their high product mix and vast global network makes demand forecasting for Zara a challenging endeavor. This thesis sets out to incorporate the effects from seasonality, product lifecycle, and cannibalization into a long term aggregate demand forecast and a short term SKU replenishment forecast. For seasonality, there are two categories of events that are explored in detail: 1) Macro patterns, which are the year to year sales patterns that remain fairly consistent, such as rising sales in spring; and, 2) Specific Events, which refers to events that have an impact on demand but shift dates from one year to the next, such as Easter or Ramadan. These two factors are used to forecast short and long term aggregated store demand by using regression that leverages historical demand with dummy variables for specific events. Product lifecycle and cannibalization are incorporated in the SKU demand forecast. Products at Zara experience a majority of their sales in the first few weeks in the store. For this reason, when forecasting demand for replenishment purposes, it is of paramount importance to understand: 1) How long the item has been in a store; and, 2) how many new items are being displayed for the first time at the store on the week in question. This thesis details a methodology that successfully uses regression to incorporate both of those components. In addition to detailing the methods for-forecasting demand this thesis also covers: an overview of the current forecasting methodology and the special characteristics of Zara's demand; a results section which detail reductions in forecast error from 21% to 17%. This has the potential to reduce lost sales by 24%; lastly, it details implementation efforts at Zara.

Texte intégralRésumé :
Integrerad produktutveckling och liknande tekniker växer i industrin. De är bevisade i forskning och i praktiken att effektivisera och öka kvalitén i produktutveckling. Model-Based Definition är en av dessa tekniker, och för att beskriva det kort är det integrerad produktutveckling realiserat med hjälp av omfattande och strategisk användning av CAD verktyg. Saab Dynamics är en tillverkare av militära produkter. De söker nu att börja använda högkvalitetsstrategin Model-Based Definition, och mer specifikt vill de modernisera mjukvaran de använder och se till att de använder den nya programvaran med en tydlig strategi i åtanke. Denna uppsats sökte att analysera implementering av Model-Based Definition i ett tidigt skede av utveckling för att förbereda Saab Dynamics att applicera denna typ av strategi för framtida produktutveckling. Detta undersöktes genom en case studie inom ett annat Saab bolag, Saab Electronic Defence Systems. Genom litteraturstudier inriktningen på arbetet bestämdes till att innehålla en stor fokus på ledningsproblematik inom Model-Based Definition. Detta för att expandera kunskapen inom området, eftersom det i nuläget är dominerat av teknikfokus. Case studien själv utfördes genom intervjuer med medarbetare på Saab EDS, med prioriteringen att urvalet ska bestå av en mångfald av medarbetare från olika funktioner, för att få ett kors-funktionellt perspektiv i resultaten. Analys av den insamlade informationen visade att även om tekniska problem inte var i fokus för undersökningen, så var det fortfarande en framstående faktor för Model-Based Definition implementering i ett tidigt skede. Dock kan det argumenteras för att det var lika mycket, om inte mer som pekar på lednings- och organisations- relaterade faktorer som viktiga för en framgångsrik Model-Based Definition strategi. Relaterat till dessa faktorer, rekommendationer för Saab att applicera i tidig implementering inkluderar bland andra: Skapa en stark laganda för att ackompanjera den huvudsakligen samarbetsrelaterade strategin, planera framtida arbete i projektet för att uppnå kortsiktiga vinster och hitta nya affärsmöjligheter för att få ett större utbrett stöd i organisationen.Concurrent 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.

Currently, demand and inventory planners at NIKE Always Available (NIKE's replenishment business) experience difficulty in managing long-lifecycle highly-seasonal products like soccer equipment and fleece apparel. Very often items are either stocked out at retailers or piling up at Distribution Centers (DCs). NIKE manages inventory to a 95% item fill rate for all replenishment products. Highly seasonal products generally have unpredictable demand patterns which lead to either stock outs or excess inventory. These imbalances in inventory occur without fully understanding the cost and benefit of holding the inventory. To understand the cost and benefit of holding inventory for long lifecycle highly seasonal products, the author analyzed the current profitability, revenue, service level, and inventory position of soccer equipment, sandals, and fleece apparel. From these results, the author modeled the benefits to the above metrics of managing inventory via a dynamic service level approach that varies the service level over the season. Next, the author modeled the benefits of managing inventory via dual-sourcing. Lastly, the author modeled the profitability impact of reducing lead times for these items. These models have shown that long lead times and high seasonality are key drivers of large safety stock quantities. Also, with highly seasonal long lead time products, dynamically managing the service level by increasing the service level at the beginning of a product's life and lowering it in its last season of life offers greater profitability than managing to a static service level. Lastly, there is an opportunity to increase the profitability of these products by changing the supply chain to enable dual-sourcing or by reducing lead times.

Texte intégralRésumé :
The management of engineering change occurs throughout product development projects. Currently, this process is well documented during the detailed design and production stages; however, little is known in terms of how the engineering change management process varies at different stages of the product lifecycle. In addition, it is not known how artefact knowledge is used and created during the enactment of the activities within the engineering change management process. Addressing this knowledge gap, this thesis presents the findings from a case study of three engineering projects and a survey of seventy nine engineering practitioners from the wider engineering community. To this end, the research reported in this thesis contributes to knowledge by offering evidence that the engineering change management process is fundamentally similar within the product lifecycle; however, eight characteristics have been found to vary. In addition, this thesis also contributes to knowledge by demonstrating the key relationship between artefact knowledge and the engineering change management process. Based on these findings, six recommendations for future engineering change management practice are offered.

Texte intégralRésumé :
Purpose: The purpose of this research is to develop a system architecture for integrating PLM systems with maintenance information to support root cause analysis by allowing engineers to visualise cross supply chain data in a single environment. By integrating product-data from PLM systems with warranty claims, vehicle diagnostics and technical publications, engineers were able to improve the root cause analysis and close the information gaps. Methodology: The methodology was divided in four phases and combined multiple data collection approaches and methods depending on each objective. Data collection was achieved through a combination of semi-structured interviews with experts from the automotive sector, by studying the internal documentation and by testing the systems used. The system architecture was modelled using UML diagrams. Findings: The literature review in the area of information flow in the supply chain and the area of root cause analysis provides an overview of the current state of research and reveals research gaps. In addition, the industry survey conducted, highlighted supply chain issues related to information flow and the use of Product Lifecycle Management (PLM) systems. Prior to developing the system architecture, current state process maps were captured to identify challenges and areas of improvement. The main finding of this research is a novel system architecture for integrating PLM systems with maintenance information across the supply chain to support root cause analysis. This research shows the potential of PLM systems within the maintenance procedures by demonstrating through the integration of PLM systems with warranty information, vehicle diagnostics and technical publications, that both PD engineers and warranty engineers were benefited. The automotive experts who validated the system architecture recognised that the proposed solution provides a standardised approach for root cause analysis across departments and suppliers. To evaluate the applicability of the architecture in a different industry sector, the proposed solution was also tested using a case study from the defence sector. Originality/Value: This research addressed the research gaps by demonstrating that: i) A system architecture can be developed to integrate PLM systems with maintenance information to allow the utilisation of knowledge and data across the product lifecycle; ii) Network can be treated as a virtual warehouse where maintenance data are integrated and shared within the supply chain; iii) Product data can be utilised in conjunction with maintenance information to support warranty and product development engineers; iv) Disparate pieces of data can be integrated where later data mining techniques could potentially be applied.

Texte intégralRésumé :
The thesis is focused on developing a set of work standards or framework to the company, Isaberg Rapid which has changed its parent company and because of it lost many of its experienced employees. Subsequently a lot of implicit knowledge is lost along with the employees, which later became evident when challenges recurred in production. The aim of the research project is to create a proof methodology to avoid this loss by storing this tacit knowledge for any references, even if the employees involved with the product are lost.
