Les travaux présentés dans cette thèse s’inscrivent dans le cadre du développement logiciel des systèmes temps réel embarqués. Nous définissons dans ce travail une méthodologie nommée DRIM. Cette méthodologie permet de guider le déploiement des applications temps réel sur différents RTOS en suivant la ligne de l’IDM et en assurant le respect des contraintes de temps après le déploiement. L’automatisation de la méthodologie DRIM montre sa capacité à détecter les descriptions non-implémentables de l’application, réalisées au niveau conception, pour un RTOS donné, ce qui présente l’avantage de réduire le temps de mise sur le marché d’une part et de guider l’utilisateur pour un choix approprié de l’RTOS cible d’autre part. / The main purpose of this Phd is to contribute to the software development of real-time embedded systems. We define in this work a methodology named DRIM: Design Refinement toward Implementation Methodology. This methodology aims to guide the deployment of a real-time application on to different RTOS while respecting MDE principals and ensuing that the timing properties are still met after deployment. The automation of DRIM shows its ability to detect non-implementable design models describing the real-time application, on aparticular RTOS, which permits to reduce the time-to-market on the one hand and guide the user to the selection of the appropriate RTOS from the other hand.

Die Telekommunikation und die ihr zuliefernde Industrie stellen einen softwareintensiven Bereich dar - der durch einen sehr hohen Anteil von Eigenentwicklungen gekennzeichnet ist. Eine wesentliche Ursache dafür sind spezielle Anforderungen an Telekommunikationssoftwaresysteme, die i.allg. nicht durch Standardsoftwareprodukte sichergestellt werden können. Diese Anforderungen ergeben sich aus den besonderen Eigenschaften solcher Softwaresysteme wie die Verteilung der Komponenten von Softwaresystemen sowie die Verteilung der Entwicklung dieser Komponenten, die Heterogenität der Entwicklungs- und Einsatzumgebungen für diese Komponenten und die Komplexität der entwickelten Softwaresysteme hinsichtlich nichtfunktionaler Charakteristika. Die industrielle Entwicklung von Telekommunikationssoftwaresystemen ist ein schwieriger und bisher nicht zufriedenstellend gelöster Prozeß. Aktuelle Forschungsarbeiten thematisieren Softwareentwicklungsprozesse und -techniken sowie unterstützende Werkzeuge zur Erstellung und Integration wiederverwendbarer Softwarekomponenten ("Componentware"). Das Ziel dieser Dissertation besteht in der Unterstützung der industriellen Entwicklung offener, verteilter Telekommunikationssoftwaresysteme. Dazu wird die Entwicklungstechnik Objektorientierte Modellierung mit dem Einsatz von Komponentenarchitekturen durch die automatische Ableitung von Softwarekomponenten aus Modellen zusammengeführt. Die zentrale Idee ist dabei eine präzise Definition der zur Entwicklung von verteilten Softwaresystemen einsetzbaren Modellierungskonzepte in Form eines Metamodells. Von diesem Metamodell ausgehend werden dann zur Konstruktion und Darstellung objektorientierter Entwurfsmodelle eine graphische und eine textuelle Notation definiert. Da die Notationen die Konzepte des Meta- Modells visualisieren, haben sie diesem gegenüber einen sekundären Charakter. Für die Transformation von Entwurfsmodellen in ausführbare Applikationen wurde auf der Grundlage von CORBA eine Komponentenplattform realisiert, die zusätzlich zu Interaktionen zwischen verteilten Softwarekomponenten auch Entwicklungs-, Deployment- und Ausführungsaspekte unterstützt. Wiederum ausgehend vom Metamodell wird durch die Anwendung wohldefinierter Ableitungsregeln die automatische Überführung von Entwurfsmodellen in Softwarekomponenten des zu entwickelnden Systems ermöglicht. Die von den Autoren erarbeiteten Konzeptionen und Vorgehensweisen wurden praktisch in eine Werkzeugumgebung umgesetzt, die sich bereits erfolgreich in verschiedenen Softwareentwicklungsprojekten bewährt hat. / The telecommunication industry and their suppliers form a software intensive domain. In addition, a high percentage of the software is developed by the telecommunication enterprises themselves. A main contributing factor for this situation are specific requirements to telecommunication software systems which cannot be fulfilled by standard off-the-shelf products. These requirements result from particular properties of those software systems, e.g. distributed development and execution of their components, heterogeneity of execution and development environments and complex non-functional characteristics like scalability, reliability, security and manageability. The development of telecommunication software systems is a complex process and currently not satisfactory realized. Actual research topics in this arena are software development processes and development techniques as well as tools which support the creation and integration of reusable software components (component ware). The goal of this thesis work is the support of the industrial development and manufacturing of open distributed telecommunication software systems. For that purpose, the development technique object oriented modelling and the implementation technique usage of component architectures are combined. The available modelling concepts are precisely defined as a metamodel. Based on that metamodel, graphical and textual notations for the presentation of models are developed. To enable a smooth transition from object oriented models into executable components a component architecture based on CORBA was also developed as part of the thesis. This component architecture covers besides the interaction support for distributed components deployment and execution aspects. Again on the basis of the metamodel code generation rules are defined which allow to automate the transition from models to components. The development techniques described in this thesis have been implemented as a tool chain. This tool chain has been successfully used in several software development projects.

Ce travail de thèse porte sur l'étude des systèmes complexes par une démarche de modélisation et simulation (M&S). La plupart des questionnements sur ces systèmes nécessitent de prendre en compte plusieurs points de vue simultanément. Il faut alors considérer des phénomènes évoluant à des échelles (temporelles et spatiales) et des niveaux de résolutions (de microscopique à macroscopique) différents. De plus, l'expertise nécessaire pour décrire le système vient en général de plusieurs domaines scientifiques. Les défis sont alors de concilier ces points de vues hétérogènes, et d'intégrer l'existant de chaque domaine (formalismes et logiciels de simulation) tout en restant dans le cadre rigoureux de la démarche de M&S. Pour répondre à ces défis, nous mobilisons à la fois des notions de modélisation multi-niveau (intégration de représentations micro/macro), de modélisation hybride (intégration de formalismes discrets/continus), de simulation parallèle, et d'ingénierie logicielle (interopérabilité logiciel, et ingénierie dirigée par les modèles). Nous nous inscrivons dans la continuité des travaux de M&S existants autour de l'approche AA4MM et du formalisme DEVS. Nous étudions en effet dans cette thèse en quoi ces approches sont complémentaires et permettent, une fois combinées dans une démarche d'Ingénierie Dirigée par les Modèles (IDM), de répondre aux défis de la M&S des systèmes complexes. Notre contribution est double. Nous proposons d'une part les spécifications opérationnelles de l'intergiciel de co-simulation MECSYCO permettant de simuler en parallèle un modèle de manière rigoureuse et complètement décentralisée. D'autre part, nous proposons une approche d'IDM permettant de décrire de manière non-ambiguë des modèles, puis de systématiser leur implémentation dans MECSYCO. Nous évaluons les propriétés de notre approche à travers plusieurs preuves de concept portant sur la M&S du trafic autoroutier et sur la résolution numérique d'un système d'équations différentielles / This thesis is focused on the study of complex systems through a modeling and simulation (M&S) process. Most questions about such systems requiere to take simultaneously account of several points of view. Phenomena evolving at different (temporal and spatial) scales and at different levels of resolution (from micro to macro) have to be considered. Moreover, several expert skills belonging to different scientific fields are needed. The challenges are then to reconcile these heterogeneous points of view, and to integrate each domain tools (formalisms and simulation software) within the rigorous framework of the M&S process. In order to solve these issues, we mobilise notions from multi-level modeling, hybrid modeling, parallel simulation and software engineering. Regarding these fields, we study the complementarity of the AA4MM approach and the DEVS formalism into the scope of the model-driven engineering (MDE) approach. Our contribution is twofold. We propose the operational specifications of the MECSYCO co-simulation middleware enabling the parallel simulation of complex systems models in a rigorous and decentralized way. We also define an MDE approach enabling the non-ambiguous description of complex systems models and their automatic implementation in MECSYCO. We show the properties of our approach with several proofs of concept

La compétitivité toujours plus importante et la mondialisation ont mis l'industrie manufacturière au défi de rationaliser les différentes façons de mettre sur le marché de nouveaux produits dans un délai court, avec des prix compétitifs tout en assurant des niveaux de qualité élevés. Le PDP moderne exige simultanément la collaboration de plusieurs groupes de travail qui assurent la création et l’échange d’information avec des points de vue multiples dans et à travers les frontières institutionnelles. Dans ce contexte, des problèmes d’interopérabilité sémantique ont été identifiés en raison de l'hétérogénéité des informations liées à des points de vue différents et leurs relations pour le développement de produits. Le travail présenté dans ce mémoire propose un cadre conceptuel d’interopération pour la conception et la fabrication de produits. Ce cadre est basé sur un ensemble d’ontologies clés, de base d’ingénierie et sur des approches de cartographie sémantique. Le cadre soutient les mécanismes qui permettent la conciliation sémantique en termes de partage, conversion et traduction, tout en améliorant la capacité de partage des connaissances entre les domaines hétérogènes qui doivent interopérer. La recherche a particulièrement porté sur la conception et la fabrication de produits tournants en plastique et explore les points particuliers de la malléabilité - la conception et la fabrication de moules. Un système expérimental a été proposé à l’aide de l'outil Protégé pour modéliser des ontologies de base et d’une plateforme Java intégrée à Jena pour développer l'interface avec l'utilisateur. Le concept et la mise en œuvre de cette recherche ont été testés par des expériences en utilisant des produits tournants en plastiques. Les résultats ont montré que l'information et ses relations rigoureusement définies peuvent assurer l'efficacité de la conception et la fabrication du produit dans un processus de développement de produits moderne et collaboratif / Global competitiveness has challenged manufacturing industry to rationalise different ways of bringing to the market new products in a short lead-time with competitive prices while ensuring higher quality levels. Modern PDP has required simultaneously collaborations of multiple groups, producing and exchanging information from multi-perspectives within and across institutional boundaries. However, it has been identified semantic interoperability issues in view of the information heterogeneity from multiple perspectives and their relationships across product development. This research proposes a conceptual framework of an Interoperable Product Design and Manufacturing based on a set of core ontological foundations and semantic mapping approaches. This framework has been particularly instantiated for the design and manufacturing of plastic injection moulded rotational products and has explored the particular viewpoints of moldability, mould design and manufacturing. The research approach explored particular information structures to support Design and Manufacture application. Subsequently, the relationships between these information structures have been investigated and the semantics reconciliation has been designed through mechanisms to convert, share and translate information from the multi-perspectives. An experimental system has been performed using the Protégé tool to model the core ontologies and the Java platform integrated with the Jena to develop the interface with the user. The conceptual framework proposed in this research has been tested through experiments using rotational plastic products. Therefore, this research has shown that information rigorously-defined and their well-defined relationships can ensure the effectiveness of product design and manufacturing in a modern and collaborative PDP

Na ultima década o paradigma de computação orientada a serviços (SOC - Service Oriented Computing) tem ganhado cada vez mais espaço na indústria e na academia, a fim de solucionar o problema da falta de comunicação entre os diversos sistemas de informação presentes dentro de um ambiente corporativo. Graças aos recentes avanços da chamada \"Web 2.0\" um novo estilo arquitetural chamado de Arquitetura orientada a Web (WOA - Web Oriented Architecture) foi proposto a fim de garantir uma maneira simples de conectar os componentes de software dinamicamente. Esse estilo tem como um dos princípios o uso de serviços Web RESTful, a fim de conseguir uma interface funcional simples e uniforme. Este trabalho apresenta um ambiente colaborativo de apoio ao desenvolvimento de serviços Web RESTful utilizando o paradigma de desenvolvimento orientado a modelos (MDD - Model Driven Development). Pretende-se mostrar os benefícios do MDD aplicado a Engenharia Web e também as vantagens apresentadas pela colaboração nesse cenário. Foi realizado ainda um experimento a fim de comprovar a eficiência do ambiente colaborativo e benefícios alcançados por ele / In the last decade the paradigm of Service Oriented Computing has gained more attention in industry and academia in order to solve the problem of lack of communication between different information systems present within a corporate environment. Due to recent advances in Web 2.0 a new architectural style called Web Oriented Architecture is proposed to ensure a simple way to connect software components dynamically. This style has as a principle the use of RESTful Web Services in order to achieve a uniform interface simple and functional. This paper presents a collaborative environment to support the development of RESTful Web Services using the Model Driven Development paradigm. It is intended to show the benefits of MDD applied to Web Engineering and also the advantages presented by collaboration in this scenario. It was also performed a experiment to prove the efficiency of the collaborative environment and benefits achieved by the same

A reutilização de software busca aumentar a qualidade e produtividade no desenvolvimento de software, evitando a duplicação do esforço e reaproveitando o máximo possível das experiências de projetos passados. Apesar de simples, esta idéia não é facilmente colocada em prática, principalmente de maneira sistemática e controlada. Técnicas de engenharia de domínio e linhas de produtos de software buscam facilitar esta tarefa, porém ainda existem outros fatores que dificultam a adoção da prática da reutilização. Entre estes, destacam-se os problemas inerentes ao desenvolvimento de software da maneira como é conduzido atualmente, baseado em código-fonte. Estes problemas têm suas origens na crescente demanda por software cada vez mais complexo e afetam negativamente a capacidade de reutilizar software. O desenvolvimento orientado a modelos surge como uma alternativa atraente neste cenário, elevando a importância de modelos dentro do ciclo de vida do software, incorporando-os como parte integrante do produto final por meio de técnicas de modelagem e geração de código. Com isto, parte da complexidade do software fica escondida dentro dos geradores, protegendo os desenvolvedores, reduzindo a incidência de erros, aumentando a produtividade, qualidade, interoperabilidade e manutenibilidade dos artefatos produzidos. Nesta dissertação defende-se a tese de que o desenvolvimento orientado a modelos pode efetivamente aumentar e/ou melhorar a reutilização de software, e que para isso ela deve ser tratada de forma consistente dentro de um processo de engenharia de domínio. Para demonstrar esta tese, é apresentada uma abordagem orientada a modelos para reutilização de software, com atividades que guiam o desenvolvedor durante a análise, projeto e implementação do domínio. São também apresentados os resultados de uma avaliação envolvendo três estudos empíricos, realizados em ambiente acadêmico e industrial, que buscou determinar a viabilidade da abordagem e os benefícios que podem ser alcançados com a combinação de técnicas do desenvolvimento orientado a modelos e da reutilização de software. Os resultados mostram que a abordagem pode trazer diferentes benefícios para organizações de software, incluindo aumento da quantidade e qualidade da reutilização, e reduzindo a complexidade de desenvolvimento e configuração de produtos / Software reuse aims at increasing quality and productivity in software development, avoiding effort duplication and reusing all past experiences possible. Although it is a simple idea, it is not easy to put reuse in practice, especially in a systematic and controlled way. Domain engineering and software product lines techniques try to make this task easier, but there are many other factors that difficult the reuse adoption. Among these factors are the problems that are inherent to software development in the way it is conducted today, based on source code. These problems arise from the growing demand for increasingly complex software, negatively affecting the ability to reuse. Model-driven development is an attractive alternative in this scenario, leveraging the importance of models in the software life cycle, incorporating them as part of the final product through modeling and code generation techniques. As a result, part of the software complexity becomes hidden inside the generators, shielding the developers, reducing errors, increasing the productivity, quality, interoperability and maintainability of the produced assets. In this dissertation is presented the thesis that model-driven development can effectively increase and/or improve software reuse, and that to achieve this goal it must be treated in a consistent way inside a domain engineering process. To demonstrate this thesis, a model-driven software reuse approach is presented, with activities that guide the developer during domain analysis, design and implementation. The results of an evaluation involving three empirical studies are also presented. The studies were performed in both academic and industrial environments, and aimed at determining the viability of the approach and the benefits that can be achieved with the combination of model-driven development and software reuse techniques. The results showed that the approach can bring different benefits to software organizations, such as software reuse quantity and quality improvements, and complexity reduction in product development and configuration tasks

Esta tese apresenta um processo para a criação de um catálogo de modelos de computação para apoiar o design de DSMLs, e a primeira versão do catálogo, com atributos que ajudam a selecionar os modelos de computação mais adequados para cada desenvolvimento de DSML, e as características dos sistemas de software para os quais esses modelos de computação são mais adequados. O contexto de aplicação desse catálogo é o Model-Driven Development (MDD desenvolvimento dirigido por modelos) a abordagem em que o desenvolvimento de software é baseado em modelos gráficos que são posteriormente traduzidos (transformados) em modelos de nível mais baixo e, no final, em código de linguagens de programação, tais como Java ou C#. A aplicação do processo gerou uma versão inicial do catálogo com os seguintes modelos de computação: diagramas BPMN, diagramas de classe da UML e regras de negócio. Visa-se contribuir para popularizar a abordagem de MDD com base em DSMLs e, em particular, a elaboração do design das DSMLs a partir de modelos de domínio, para o que o uso do catálogo efetivamente contribui. / This thesis presents a process for the creation of a catalog of models of computation to support the design of Domain-Specific Modeling Languages (DSMLs), and the first version of the catalog, which comprises attributes that aim to help the selection of the most suitable models of computation for each DSML development, and characteristics of software systems for which these models of computation are more appropriate. The context for the use of the catalog is the Model-Driven Development (MDD) - the approach where software development is based on graphical models that are subsequently translated (transformed) into lower-level models and, in the end, in source code in programming languages, such as Java or C #. The process was applied to generate an initial version of the catalog with the following models of computation: BPMN diagrams, UML class diagrams and business rules. It aims to contribute to popularize the MDD approach based in DSMLs, and in particular, the development of the DSMLs design from domain models, for which the use of the catalog effectively contributes.

Model-Driven Development is a development approach which is being used frequently in the automotive context in order to design models. EAST-ADL is an architectural language which models systems according to their architectural features, whereas Simulink is a tool environment which models systems according to their behavior. In this thesis work, we propose a set of transformation rules that take into consideration the EAST-ADL architectural model details and the behavioral specifications in Simulink, and generate a formal model, which can be verified UPPAAL model checker. Moreover, we implement these proposed transformation rules in a tool that automates them. The transformation rules proposed in this thesis work would be implemented for every EAST-ADL file with Simulink behavior specifications, generated by the MetaEdit+ tool. Properties like timing constraints, triggering and hierarchy in both EAST-ADL and Simulink have been considered by the transformation rules. Finally, the Brake-by-Wire case study is used to validate the tool and assess the mapping of the elements.
