L'évolution rapide des besoins dus entre autres à l'innovation technique, la concurrence ou la réglementation conduit souvent à décrire le cadre d'étude des systèmes d'information dans des modèles conceptuels, pour faciliter l'évolution du fonctionnement des systèmes. La mise au point de ces modèles s'effectue en plusieurs phase au cours desquelles collaborent plusieurs équipes de nature différente, chaque intervenant apportant sa perception du système à construire en se limitant à la partie de son domaine de spécialisation. Il faut alors concilier les différentes perceptions. L'objectif essentiel de la thèse est de concevoir les mécanismes permettant d'une part d'obtenir le modèle factorisant les concepts communs à plusieurs modèles et, d'autre part, de proposer aux concepteurs une méthodologie de suivi de l'évolution de la factorisation. Pour réaliser la factorisation, nous avons mis en œuvre l'Analyse Formelle de Concepts et l'Analyse Relationnelle de Concepts (ARC) qui sont des méthodes d'analyse de données basées sur la théorie des treillis. Dans un ensemble d'entités décrites par des caractéristiques, les deux méthodes extraient des concepts formels qui associent un ensemble maximal d'entités à un ensemble maximal de caractéristiques partagées. Ces concepts formels sont structurés dans un ordre partiel de spécialisation qui les munit d'une structure de treillis. L'ARC permet de compléter la description des entités par des relations entre entités. La première contribution de la thèse est une méthode d'analyse de l'évolution de la factorisation d'un modèle basée sur l'AFC et l'ARC. Cette méthode s'appuie la capacité de l'AFC et de l'ARC à faire émerger au sein d'un modèle des abstractions thématiques de niveau supérieur, améliorant ainsi la sémantique des modèles. Nous montrons que ces méthodes peuvent aussi être employées pour suivre l'évolution du processus d'analyse avec des acteurs. Nous introduisons des métriques sur les éléments de modélisation et sur les treillis de concepts qui servent de base à l'élaboration de recommandations. Nous effectuons une expérimentation dans laquelle nous étudions l'évolution des 15 versions du modèle de classes du système d'information SIE-Pesticides. La seconde contribution de la thèse est une étude approfondie du comportement de l'ARC sur des modèles UML. Nous montrons l'influence de la structure des modèles sur différentes variables étudiées (comme les temps d'exécution et la mémoire occupée) au travers de plusieurs expérimentations sur les 15 versions du modèle SIE-Pesticides. Pour cela, nous étudions plusieurs configurations (choix d'éléments et de relations dans le méta-modèle) et plusieurs paramètres (choix d'utiliser les éléments non nommés, choix d'utiliser la navigabilité). Des métriques sont introduites pour guider le concepteur dans le pilotage du processus de factorisation et des recommandations sur les configurations et paramétrages à privilégier sont faites. La dernière contribution est une approche de factorisation inter-modèles afin de regrouper au sein d'un modèle l'ensemble des concepts communs à différents modèles sources conçus par différents experts. Outre le regroupement des concepts communs, cette analyse produit de nouvelles abstractions généralisant des concepts thématiques existants. Nous appliquons notre approche sur les 15 versions du modèle du SIE-Pesticides. L'ensemble de ces travaux s'inscrit dans un cadre de recherche dont l'objectif est de factoriser des concepts thématiques au sein d'un même modèle et de contrôler par des métriques la profusion de concepts produits par l'AFC et surtout par l'ARC. / The rapidly changing needs among other things due to technical innovation, competition and regulation often leads to describe the context for the study of conceptual models in information systems to facilitate the evolution of operating systems. The development of these models is carried out in several phases during which several working teams of different nature, providing each participant's perception of the system to be built is limited to the part of his area of specialization. It must then reconcile the different perceptions.The main objective of the thesis is to design mechanisms to obtain a share of the model factoring concepts common to several models and, secondly, to provide designers with a methodology for monitoring the evolution of factorization.To perform the factorization, we have implemented the Formal Concept Analysis and Relational Concepts Analysis (RCA), which are methods of analysis based on the theory of lattice data. In a set of entities described by features, both methods extract formal concepts that combine a maximum of entities to a maximum set of shared characteristics together. These formal concepts are structured in a partial order of specialization that provides with a lattice structure.The CRA can complement the description of the entities by relationships between entities.The first contribution of the thesis is a textbf {method a model for analyzing the evolution of the factorization based on the FCA and the RCA}. This method builds the capacity of the AFC and the CRA to emerge in a model of thematic abstractions higher level, improving semantic models. We show that these methods can also be used to monitor the analytical process with stakeholders. We introduce metrics on the design elements and the concept lattices which are the basis for the development of recommendations. We conduct an experiment in which we study the evolution of the 15 versions of the model class of information-Pesticides EIS system.The second contribution of this thesis is a textbf {depth study of the behavior of the RCA on UML models.} We show the influence of model structure on different variables studied (such as execution time and memory used) through several experiments on 15 versions of the EIS-Pesticides model. For this, we study several configurations (choice of elements and relations in the meta-model) and several parameters (choice of using unnamed elements, choice of using airworthiness). Metrics are introduced to guide the designer in managing the process of factoring and recommendations on the preferred configurations and settings are made.The last contribution is a textbf {approach to inter-model factorization} to group in a model all the concepts common to different source models designed by different experts. In addition to the consolidation of common concepts, this analysis produces new abstractions generalizing existing thematic concepts. We apply our approach on 15 versions of the model EIS-Pesticides.All this work is part of a research framework which aims to factor thematic concepts within a model and control metrics by the profusion of concepts produced by the FCA and especially by RCA.

1 EINFÜHRUNG Der Beitrag diskutiert ein Vorgehensmodell zur Übertragung eines Vernetzungsansatzes für sehr kleine Wertschöpfungseinheiten, vornehmlich aus dem Maschinenbau, in die Domäne Dezentrale Energieversorgung. Es handelt sich dabei um den kompetenzzellenbasierten Vernetzungsansatz (KVA), ein Artefakt des DFG-Forschungsprojektes „Hierarchielose regionale Produktionsnetze“ (Sonderforschungsbereich 457). Das Lernen setzt die Analyse sowie das Erkennen und Verstehen des Forschungsgegenstandes KVA voraus. Von besonderem Interesse sind die Forschungsergebnisse zu den aufbau- und ablauforganisatorischen Grundbetrachtungen über die Zusammenarbeit von Kompetenzzellen. Können diese Ergebnisse einen wissenschaftlichen und praktischen Nutzen für die Organisation von Anbietergemeinschaften aus Stromerzeugern und -verbrauchern stiften? Dazu werden das Gestaltungskonzept Zwei-Ebenen-Kooperation und das Konzept der Kompetenzzelle untersucht. Für die Übertragung wird die Modellierungssprache Unified Modeling Language 2 (UML2) zur Beschreibung von Struktur, Funktion und Organisation vorgeschlagen.

[pt] O ensino de computação gráfica aplicada é de muita importância no processo de simulação computacional de problemas de engenharia. Atualmente, muitos programas de computador, de fácil utilização, têm melhorado este trabalho, como é o caso do MATLAB. A geração e manipulação de um modelo geométrico, que é a forma mais realista e apropriada de representar o problema a ser estudado, são etapas muito importantes na simulação computacional. O uso do mouse permite que estas etapas se tornem mais interativas e de fácil compreensão. Por este motivo, neste trabalho desenvolve-se uma classe genérica no contexto da programação orientada a objetos, no ambiente MATLAB, que permite gerenciar eventos de mouse em um canvas. O objetivo desta classe é ser utilizada no desenvolvimento de programas gráficos e interativos em MATLAB, principalmente para fins educacionais. Visando atender a essas expectativas, adotou-se a Orientação a Objetos, que possibilita a criação de códigos reutilizáveis. Aliada a essa técnica, utiliza-se a Unified Modeling Language, uma linguagem gráfica que permite a visualização, construção e documentação do desenvolvimento de um sistema computacional orientado a objetos. Para determinar o correto funcionamento e praticidade da classe desenvolvida, são implementadas duas aplicações interativas no software MATLAB; a primeira para desenhar pórticos planos em 2D e a segunda para demostrar o funcionamento do círculo de Mohr para estado plano de tensões. / [en] Teaching of applied computer graphics is of great importance in computational simulation of engineering problems. Currently, many user- friendly computer programs have improved this work, as is the case with MATLAB. The generation and manipulation of a geometric model, which is a more realistic and appropriate way to represent the problem to be studied, are very important steps in the computational simulation. The use of the mouse allows these steps to become more interactive and easy to understand. For this reason, in this work a generic class is developed in the context of object-oriented programming (OOP) in the MATLAB environment, which allows managing mouse events in a canvas. The goal of this OOP class is to be used as a base class in the development of graphics and interactive programs in MATLAB, mainly for educational purposes. In order to meet these expectations, an OOP paradigm was adopted, which enables the creation of reusable codes. Together to this technique, the Unified Modeling Language (UML) is used, a graphic language that allows the visualization, construction and documentation of the development of an object oriented computational system. To determine the correct functioning and practicality of the developed class, two interactive applications are implemented in MATLAB; the first to draw frame structures in 2D and the second to demonstrate the Mohr circle for stress state.

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / Architectural specification of real-time software systems is an activity that conveys analysis, knowledge and understanding of both the application domain and the parties involved in software construction. Architecture plays a key role in communication between stakeholders, in addition to planning the entire architectural process involved in the project. However, Architecture Description Languages (ADLs) have not been widely used in the industry. Another limiting factor for the e ff ective use of ADLs is the di ffi culty of these languages in e ff ectively expressing the architecture of complex systems. Considering this situation of di ffi culty in the e ff ective use of ADLs, the UML has been used in recent years to model the architecture. However, UML can not represent the important characteristics pertinent to real-time systems, such as security or real-time constraints. One of the advantages of the UML is the extensibility allowing the creation of profiles. In this sense, this work proposes using Systems Modeling Language (SysML), a UML profile, to model real-time systems architecture in two automotive systems, the airbag control system and the light control system. The objective of this work is to use UML and SysML to model and document the architecture and design of requirements traceability between software and systems elements, increasing the understanding of the project among the parties involved, and finally presenting SysML as a language for description of real-time software architecture. The ADL Architecture Analysis and Design Language (AADL) and SysML languages were compared to show the advantages of SysML. As a result, it was noticed that abstract features such as conditional deviations, loop, characteristics that are related to reality and consequently to the system can not be described in AADL. SysML has proved to be relevant in the context of architecture description, analysis, classification and modeling of real-time systems. The SysML Requirements diagram explicitly shows the various types of relationships between di ff erent requirements, the Block diagram enables the global view of the systems involved in a single project, the Internal Block diagram allows the internal view of the system under construction, the Activity diagram considers the behavioral view of the system. SysML concepts, articulated in the SysML Requirements, Activities, Blocks and Internal Blocks diagrams, are complementary, covering the purposes needed to describe the architecture of real-time systems. It is concluded that the proposed UML and SysML join technique provides elements to describe software requirements and their relationships with the system, to manage changes, to evolve and to trace requirements more easily, in addition to the communication being e ff ectively carried out between the stakeholders. This is important for the development of real-time systems because of the diversity of people / teams involved and influencing a wide range of design decisions. / A especificação da arquitetura de sistemas de software de tempo real é uma atividade que depreende análise, conhecimento e compreensão tanto do domínio da aplicação quanto das partes envolvidas na construção do software. A arquitetura tem um papel primordial na comunicação entre os stakeholders, além do planejamento de todo o processo arquitetural envolvido no projeto. Contudo, as Linguagens de Descrição de Arquiteturas (ADLs) não têm sido amplamente usadas na indústria. Outro fator limitador para o uso efetivo de ADLs é a dificuldade dessas linguagens em expressar efetivamente a arquitetura de sistemas complexos. Considerando essa situação de dificuldade do uso efetivo de ADLs, a UML tem sido utilizada nos últimos anos para modelagem da arquitetura. No entanto, a UML não consegue representar características importantes pertinentes a sistemas de tempo real, tais como segurança ou restrições de tempo real. Uma das vantagens da UML é a capacidade de extensão permitindo a criação de profiles. Neste sentido, este trabalho apresenta a Systems Modeling Language (SysML), um profile da UML, para modelagem da arquitetura de sistemas de tempo real em dois sistemas automotivos, o sistema de controle de airbag e o sistema de controle de faróis. Neste trabalho tem-se como objetivos utilizar a UML e a SysML para modelagem e documentação da arquitetura e delineamento de rastreabilidade de requisitos entre software e sistema, ampliando o entendimento do projeto entre as partes envolvidas, e por fim apresentar a SysML como uma linguagem para descrição da arquitetura de software de tempo real. As linguagens SysML e a ADL Architecture Analysis & Design Language (AADL) foram comparadas para mostrar as vantagens da SysML. Como resultado, foi percebido que características abstratas, tais como tomadas de decisão, repetição de uma funcionalidade (loop), características que são relacionadas a realidade e, consequentemente, ao sistema, não podem ser descritas em AADL. A SysML mostrou-se relevante no contexto da descrição, análise, classificação e modelagem de arquitetura para sistemas de tempo real. O diagrama de Requisitos da SysML mostra explicitamente os diversos tipos de relacionamentos entre diferentes requisitos, o diagrama de Blocos viabiliza a visão global dos sistemas envolvidos num único projeto, o diagrama de Blocos Internos possibilita a visão interna do sistema em construção, o diagrama de Atividades considera a visão comportamental do sistema. Os conceitos de SysML, articulados nos diagramas de Requisitos, Atividades, Blocos e Blocos Internos da SysML são complementares cobrindo os propósitos necessários para a descrição da arquitetura de sistemas de tempo real. Conclui-se que a técnica proposta da junção de UML e SysML fornece elementos para descrever requisitos de software e seus relacionamentos com o sistema, gerenciar mudanças, evoluir e rastrear requisitos mais facilmente, além da comunicação ser efetivamente realizada entre os stakeholders. Este aspecto é importante ao desenvolvimento de sistemas de tempo real, por causa da diversidade de pessoas / equipes envolvidas e que influenciam uma ampla série de decisões de projeto.

The project focuses on the packaging process of the smart card manufacturing industry. The idea of the project concerns how to increase production packaging efficiency by introducing a control system. After taking an in-depth look at the current production environment, the following system goals were defined: packaging time reduction, cost reduction, decrease in human errors, and reducing the number of customer complaints. To achieve these goals, the thesis project was divided into the following tasks: discovering a feasible solution, actual system development, testing, and evaluation. The proposed system is based on hardware (i.e. barcode scanner, and barcode printer) integrated with customized control software. The barcode scanner acts as a bridge between the system and the production process by scanning a barcode printed on each product. The system prints the required information label for the product’s package according to the scanned product. This label is pasted on the product’s box and is used as a tracking tool during further production steps. The system is very flexible and suits any packaging model. Other functional properties maintained in the system include data security, product traceability, and real time production monitoring. Testing of the system was done in an actual production environment at an Oberthur Technologies manufacturing site. Two production lines were selected to test the system’s functionality, specifically the SIM card production packaging line and the Scratch card/ Bank Card production packaging line. The results obtained during the evaluation phase of the proposed system show that the proposed solution decreased the packaging processing time by (27.3%) over the previous values. Moreover, the resulting human error rate is close to (zero%). / Projektet fokuserar på förpackningen processen smartkortet tillverkningsindustrin. Tanken med projektet handlar om hur att öka effektiviteten produktionen förpackningar genom att införa ett styrsystem. Efter att ha tagit en fördjupad titt på den nuvarande produktionsmiljö, var följande systemkrav mål definieras: nedsättning förpackning tid, minskade kostnader, minskad mänskliga fel och minska antalet kundklagomål. För att uppnå dessa mål var examensarbetet indelad i följande uppgifter: att upptäcka en genomförbar lösning, faktisk systemutveckling, testning och utvärdering. Det föreslagna systemet bygger på hårdvara (dvs streckkodsläsare och streckkod skrivare) integreras med skräddarsydd styrprogram. Den streckkodsläsare fungerar som en bro mellan systemet och produktionsprocessen genom att läsa en streckkod tryckt på varje produkt. Systemet skriver den erforderliga informationen etiketten för produktens förpackning enligt den scannade produkten. Denna etikett klistras in på produktens ask och används som ett verktyg för spårning under ytterligare produktionssteg. Systemet är mycket flexibelt och passar varje förpackning modell. Andra funktionella egenskaper bibehålls i systemet inkluderar datasäkerhet, spårbarhet och i realtid övervakning av produktionen. Testning av systemet gjordes i en verklig produktionsmiljö i ett Oberthur Technologies tillverkningsanläggning. Två produktionslinjer valdes för att testa systemets funktionalitet, särskilt i SIM-kortet produktionen förpackning linje och skrapkort / Bank kortproduktion förpackningslinje. De resultat som erhållits under utvärderingsfasen av det föreslagna systemet visar att den föreslagna lösningen minskade tiden förpackningen behandling av (27,3 %) jämfört med föregående värden. Dessutom är den resulterande mänskliga fel som ligger nära (noll %).

Die Konfrontation mit innovativen IT-Technologien und deren Beurteilung gehört heute zu den Kernaufgaben des Informationsmanagements. Es muss permanent entscheiden, ob neue IT-Technolgien im Unternehmen nutzenstiftend eingesetzt werden können. Zur Beurteilung von IT-Projekten liefert die Teildisziplin des IT-Controllings, die Elemente der Wirtschaftsinformatik und des Controllings vereint, diverse Methoden und Ansätze. Diese Ansätze bilden die Basis für die vorliegende Arbeit, in der insbesondere der Aspekt der Nutzenbewertung von IT-Innovationen diskutiert wird. Bei der Bewertung von IT-Innovationen treten spezifische Probleme auf, denen der Autor mit der Fortentwicklung der vorhandenen Instrumente begegnet. Der Einsatz von unscharfen Methoden (Fuzzy Logik) führt zu einer adäquaten Darstellung von vagen Größen in Form von Zugehörigkeitsfunktionen. Durch den Einsatz von Regelbasen wird ein Expertenwissen repräsentiert, das die Analysemethode nach außen hin vereinfacht und somit zu einer effizienteren Nutzenbetrachtung führt. Die Auswahl und Initiierung von innovativen IT-Projekten wird durch ein Vorgehensmodell gestützt, das bei der fundamentalen Fragestellung nach Schwachstellen und Verbesserungspotentialen im Unternehmen ansetzt. Für diese Analyse wird auf die Erfolgsfaktorenanalyse zurückgegriffen, die durch individuelle Faktoren angepasst wird. Aus den analysierten Schwachstellen werden innovative IT-Projekte abgeleitet und definiert. Die Aufstellung der Nutzenkriterien erfolgt aus einem allgemeinen Nutzenkatalog, der mit den analysierten Erfolgsfaktoren korrespondiert. Die konkrete Bewertung der Projekte erfolgt durch die fuzzybasierte Nutzenbewertung und liefert prägnante Empfehlungen zu den einzelnen Projekten. Die Integration des Vorgehensmodells in das IT-Controlling erfordert eine automatisierte Form, die aufgrund der UML Notation generiert werden kann. Die prototypische Umsetzung und Verwendung der unscharfen Nutzenanalyse haben gezeigt, dass die Methodik für den praktischen Einsatz tauglich ist.
