L’impact de ce travail de doctorat se concentre sur l’inclusion sociale des Personnes en Situation de Handicap (PSH). Cette inclusion dépend de plusieurs d’initiatives comme l’Accessibilité des espaces et des informations mais aussi de l’offre de Produits d’Assistance (PA) qui peuvent soulager voire compenser les situations de handicap. Notre travail se place sur ce second terrain, en particulier sur les insatisfactions et abandons des PA par les PSH et la difficulté des fabricants à offrir une variété de produits ciblés sur besoins et avec des prix abordables. Nous pensons que la solution à une telle pro-blématique peut être faite dès la conception des PA. Ainsi, nous proposons un modèle de référence pour l’organisation du processus de conception de ces produits autour d’une philosophie et d’une méthodologie de conception. Ce modèle a été construit à partir de recherches bibliographiques sur les processus de conception de produits de manière générale, telles que la conception lean et la customi-sation de masse, et aussi quelques approches et modèles de conception de produits qui intègrent les PSH dans le public de consommateurs. Suite à son développement, la proposition a été testée et amé-liorée à partir de deux cas d’étude réalisés dans le cadre de la Mobilité Personnelle. Le premier cas d’étude se concentre sur la conception de Dispositifs d’Aide à la Marche (DAM), tels que les cannes, les béquilles et les cadres de marche. Ensuite, la deuxième expérience est focalisée sur la conception de Véhicules non-motorisés (VNM), comme les cycles et les fauteuils roulants. Le résultat de ces expéri-mentations et les révisions du modèle de référence pour la conception de PA nous ont permis d'abou-tir à une configuration des principes et à une méthodologie qui accordent les attentes tangibles et in-tangibles des PSH à travers la conception et l’offre de produits personnalisables tout en respectant les exigences des systèmes de fabrication et distribution. / The impact of this PhD work focuses on the social inclusion of Persons with Disabilities (PWD). This inclusion depends on several initiatives such as spacial and informational accessibility, and the offer of Assistive Products (AP), which can alleviate or compensate disability situations. Our work focuses on this second point, particularly under the dissatisfaction and abandonment of AP by the PWD and the inability of the manufacturers to offer a variety of products that respond to the users’ needs with affordable prices. We believe that the solution to this problem can be found in the AP design process. Thus, we propose a reference model for the a AT design process organization around a philosophy and a design methodology. This model was constructed from bibliographic research on product de-sign processes in general, such as lean design and mass customization, as well as some product design approaches and models that integrate the PWD as customers. After this, the proposal was tested and improved through two case studies carried out in the Personal Mobility context. The first case study focuses on the design of Walking Aid Devices (WADs), such as walking sticks, crutches and walking frames. Second, the second one focuses on the design of non-motorized vehicles (NMVs), such as cycles and wheelchairs. The result of these experiments and the revisions of the reference model for AP design enabled us deliver a configuration of principles and a methodology of design that matches the tangible and intangible expectations of the PWD through the conception and offering of customi-zed products that respond to the requirements of manufacturing and distribution systems.

[pt] A Indústria Automotiva vem passando por grandes transformações que implicam em mudanças na Gestão de suas Cadeias de Suprimentos (Supply Chain Management - SCM). A acirrada competição existente no mercado globalizado vêm forçando as montadoras a buscarem novas vantagens competitivas. Diferentes modelos de produção de veículos vêm sendo introduzidos procurando alcançar nichos de mercado. Porém, o cliente ainda se vê obrigado a se satisfazer com a oferta de veículos disponíveis no mercado, que muitas vezes estão fora de suas reais necessidades e preferências. Além disso, os custos de imobilização de capital ao longo da Cadeia de Suprimentos continuam muito elevados. O autor desta dissertação procura então investigar os principais métodos e modelos de produção de veículos da Indústria Automotiva e esclarecer os conceitos de Customização em Massa e de Produção sob Encomenda (Build to Order – BTO), tendências que aparecem como alternativas para as montadoras de veículos aumentarem sua competitividade. O presente trabalho parte dos principais métodos de produção da Indústria Automotiva como a Produção Artesanal, a Produção em Massa e a Produção Enxuta destacando suas principais características, passa pelos modelos de produção procurando ressaltar as diferenças existentes entre eles, para, então, chegar aos conceitos, benefícios, desafios e outras particularidades das Tendências de Produção sob Encomenda e de Customização em Massa. A dissertação procura, finalmente, analisar os métodos e modelos de produção de veículos sob a ótica destas tendências. / [en] The Automotive Industry has been going through great transformations that are calling for modifications in its Supply Chain Management (SCM). The huge competition on the current globalized market have been compelling the vehicles manufacturers to search for new competitive advantages. Different vehicles production models have been introduced in order to reach market niches. However, the customer is still obligated to be satisfied with the available vehicles in the market, which often do not match with their real needs and preferences. Besides, the cost of capital immobilization along the supply chain continues very high. The author of this dissertation wishes to investigate the main vehicles production methods and models in the Automotive Industry and to present the Mass Customization and Build to Order concepts, trends that come as alternatives to vehicles manufacturers to increase it competition. This work starts with the main production methods in the Automotive industry, as Handcraft Production, Mass Production, and Lean Production highlighting its.

Embora o projeto de uma família de produtos é uma tarefa difícil e desafiadora, derivar os membros da família de produtos para atender os requisitos de clientes individuais pode ser uma tarefa de design rotineira. Neste trabalho, propomos uma abordagem formal para modelar o processo de customização de famílias de produtos, que alcançar este objetivo. De fato, construímos uma teoria para a customização de famílias de produtos. Esta abordagem é baseada em uma estrutura de conhecimento para a representação de famílias de produtos que combina uma estrutura de produto genérica e uma rede de restrições estendida com funções de design. O método para derivar os membros da família de produtos é um processo de instanciação com duas fases. Primeiramente, uma solução para o modelo de rede de restrição consistente com os requisitos do cliente é encontrada. Em seguida, esta solução é utilizada para transformar a estrutura de produto genérica em uma estrutura especifica que corresponde a um membro da família de produtos. Neste trabalho, provamos que, se o modelo de rede de restrição estendida com funções de design satisfaz algumas condições de modelagem, então encontrar soluções se torna um processo livre de retrocessos. Embora existam outros trabalhos na literatura que também afirmam ser livre de retrocessos, um fato notável sobre a nossa abordagem é que conseguimos isso através da introdução de conhecimento sobre a família de produtos, em vez de recorrer ao poder computacional e pré-processamento como naquelas abordagens. Outro aspecto notável da nossa abordagem é que os componentes podem ser projetados como parte do processo de personalização através das funções de design. Isto implica que é possível dispor de um processo de customização eficiente sem comprometer a flexibilidade da família de produtos. Na conclusão deste trabalho, argumentamos que a nossa abordagem pode lidar com problemas de customização que estão fora da área de configuração de produtos. Dois apêndices também são adicionados à tese. Um deles é uma modelagem completa de uma família de produtos Chave de Transferência Automática (ATS) baseado em nossa abordagem. Este exemplo é usado no corpo principal da tese para ilustrar os conceitos que estão sendo introduzidos. A outra é uma implementação computacional do primeiro estágio do processo de customização da família de produtos ATS / Abstract: Product family is a key concept is the area of mass customisation. Although the design of a product family is a difficult and challenging task, to derive members of the product family to meet the requirements of individual customers can be a routine design task. In this work, we propose a formal approach to model the customisation of product families that achieves this goal. In fact, we are setting up a theory for the customization of product families. This approach is based on a knowledge framework for the representation of product families, which combines a generic product structure and a constraint network extended with design functions. The method for deriving members of the product family is a two-stage instantiation process. First, a solution to the constraint network model consistent with the customer requirements is found. Next, this solution is used to transform the generic product structure into a specific structure that corresponds to a member of the product family. In this work, we prove that if the constraint network model extended with design functions satisfies a few modelling conditions, then to find solutions become a backtrack-free process. Although there are other works in the literature that also claim to be backtrack-free, a remarkable fact about our approach is that we achieve this by the introduction of knowledge about the product family, instead of resorting to computational power and pre-processing as in those approaches. Another remarkable aspect of our approach is that components can be designed as part of the customisation process using the design functions. This implies that it is possible to have an efficient customisation process without compromising the flexibility of the product family. In the conclusion of this work, we argue that our approach can deal with customisation problems outside the product configuration area. Two appendixes are also added to the thesis. One is a compete modelling of the Automatic Transfer Switch (ATS) product family using our approach. This example is used in the main body of the thesis to illustrate the concepts that are being introduced. The other one is the computational implementation of the first-stage customisation process of the ATS product family / Doutorado / Telecomunicações e Telemática / Doutor em Engenharia Elétrica

Custom software development and maintenance is one of the key expenses associated with developing automated systems for mass customization. This paper presents a method for reducing the risk associated with this expense by developing a flexible environment for determining and executing dynamic workflow paths. Strategies for developing an autonomous agent-based framework and for identifying and creating web services for specific process tasks are presented. The proposed methods are outlined in two different case studies to illustrate the approach for both a generic process with complex workflow paths and a more specific sequential engineering process.

When it comes to cloud services, security has many a times been the hot topic. This has been especially relevant within the payment card industry and the secure handling of payment card data. The Payment Card Industry Security Standards Council (the council) was formed in order to ensure a global enhancement of payment card data. The council has issued requirements that all companies that handle payment card data are obliged to follow. However, the council has become much more strict as of recently, creating an urgency to become compliant. Thus, cloud service providers (CSP) have constructed standardized, PCI DSS compliant products so as to relief such customers. Since this emerging market is somewhat new, this thesis has researched how CSPs should relate to products within that market and the potential customer base. The case study for this research was conducted at Tieto, an IT service company, and its standardized, PCI DSS compliant product TiCC. The study collected empirical data in the form of qualitative interviews as well as quantitative telephone interviews with companies within the payment card industry. The study came to the conclusion that there is a demand that is not being met within the payment card industry related to products that aid organizations to become PCI DSS compliant. Standardized products have been constructed so as to fit financial customers while overlooking the demand of another large customer base, retail. Additionally, the products are being tweaked and features are being added, thus providing customization. CSPs are striving for both standardization as well as customization, something that has been considered counterproductive. The existing demand is thus not met with the current supply in the market, which has both multiple competitors and heterogeneity in market demand. The above mentioned thus leaves room for market seizure, to create own rules and thus making all competitors irrelevant. A potential way of doing that is through mass customization by standardizing higher levels of cloud computing.

Les approches conventionnelles pour la génération de processus de fabrication sont inefficaces pour gérer la complexité induite par la variété des produits et la dynamique de fabrication. La génération des processus de fabrication reconfigurables (RPP) est une nouvelle méthode de CAPP qui vise à générer des processus de fabrication pour une famille de produits / pièces. Cette thèse vise à apporter une contribution majeure aux modèles de représentation et aux méthodes de génération permettant la génération des processus de fabrication reconfigurables à deux niveaux de granularité : famille de produits et famille de pièces. Les approches proposées pour le RPP sont compatibles avec une extension du concept de famille de produits / pièces qui est défini en utilisant le concept de domaine. Un modèle pour une variété fonctionnelle de produit / pièce basé sur des entités est développé afin de représenter les informations nécessaires à la gestion des processus reconfigurables en utilisant des techniques modulaires. Des modèles mathématiques et des modèles de représentation sont proposés pour décrire le processus de fabrication reconfigurable à deux niveaux de granularité. Sur la base des modèles de représentation, les méthodes de génération et les algorithmes sont ensuite détaillés dans ce cadre. En outre, un cadre global est proposé pour décrire comment les modèles et les méthodes proposés collaborent pour gérer la variété de produit / pièce et la dynamique de fabrication. Pour illustrer la faisabilité des modèles et méthodes proposés, deux familles de pompes (l’une à engrenage et l’autre à huile) sont utilisées à titre d'exemples illustratifs tout au long de ce mémoire de thèse. / Conventional manufacturing process planning approaches are inefficient to handle the process planning complexity induced by product variety and manufacturing dynamics. Reconfigurable process planning (RPP) is an emerging CAPP approach targeting to the generation of process plans for a product/part family. This thesis aims to give major contributions to the representation models and generation methods to support reconfigurable process planning at two granularity levels: product family and part family. The proposed approaches for RPP are compatible with an extended concept of product/part family which is defined by using the concept of “domain”. A feature-based product/part variety model is developed to represent the required information for RPP by using modular and platform-based techniques. Mathematical models and graph-based representation models are proposed to describe the reconfigurable process plan at two granularity levels. Based on the representation models, the generation methods and algorithms are then developed for RPP. In addition, a global framework is proposed to describe how the proposed RPP models and methods work together to handle the product/part variety and manufacturing dynamics. To test the feasibility of the proposed models and methods, a gear pump family and an oil pump body family are used as illustrative examples throughout this thesis.

Market globalization and mass customization requirements are forcing companies towards automation of their product development processes. Many task-specific software solutions provide localized automation. Coordinating these local solutions to automate higher-level processes requires significant software maintenance costs due to the incompatibility of the software tools and the dynamic nature of the product development environment. Current automation methods do not provide the required level of flexibility to operate in this dynamic environment. An autonomic product development process automation strategy is proposed in order to provide a flexible, standardized approach to product development process automation and to significantly reduce the software maintenance costs associated with traditional automation methods. Key elements of the strategy include a formal approach to decompose product development processes into services, a method to describe functional and quality attributes of services, a process modeling algorithm to configure processes composed of services, a method to evaluate process utility based on quality metrics and user preferences, and an implementation that allows a user to instantiate the optimal process. Because the framework allows a user to rapidly reconfigure and select optimal processes as new services are introduced or as requirements change, the framework should reduce burdensome software maintenance costs associated with traditional automation methods and provide a more flexible approach.
