Este trabalho propõe um método de representação e análise de cadeias de suprimentos que visa permitir a identificação e conseqüente eliminação dos desperdícios que ocorrem ao longo de uma cadeia produtiva. Fundamentado nos conceitos de gestão da cadeia de suprimentos, produção enxuta e modelagem de empresas, este trabalho tem como principal justificativa a necessidade de se desenvolver mecanismos que possibilitem a integração entre empresas, melhorando os níveis de coordenação e sincronização dos fluxos de materiais e informações. O mapeamento do fluxo de valor, técnica de modelagem desenvolvida por ROTHERS & SHOOK (1998), visa auxiliar a obtenção de sistemas produtivos enxutos e foi utilizada como base para o desenvolvimento do método. Dois aspectos são levados em conta para a proposição do método: o primeiro diz respeito ao conteúdo de informações dos modelos e o segundo ao procedimento de aplicação. A principal característica do método é a decomposição em três níveis de mapeamento, indo de um nível mais genérico para um nível de maiores detalhes. Uma ilustração de um caso hipotético de aplicação é fornecida como exemplo. Como conclusões são expostas as vantagens e limitações percebidas no método. Os trabalhos futuros sugeridos se referem à avaliação, aplicação e complementação do método. / This work proposes a method for supply chain representation and analysis to allow the identiJication and consequent elimination of the waste in the production chains. The fundamental concepts this work is based on are: supply chain management, lean production and enterprise modeling. The main reason for the development of this research is the need of developing tools and mechanisms to help the integration between enterprises, improving the coordination and synchronization of the material and information flows. The Value Stream Mapping technique, developed by ROTHERS & SHOOK (1998), which helps the design of lean production systems, is used as a basis for the development of the method. Two aspects were observed during the development of the method: the first one deals with the information content of the models and the second one with the application procedure of the method. The main characteristic of the method is the decomposition in three levels of mapping, from a generic level to a more detailed one. An illustration based on a hypothetic case is given as an example. At the conclusion of this work the advantages and limitations of the method are discussed. Some future researches are suggested based on the evaluation, application and complementation of the method.

No atual contexto do planejamento e controle da produção, existe uma necessidade de uma melhor utilização do processo de negócio que norteia o desenvolvimento de todos os seus planos, conhecido como gestão da demanda. Nesse assunto, a existência de literatura adequada e de modelos ou formalismos que visam facilitar a compreensão e utilização do processo em si, é rara, e por muitas vezes, insuficiente. Dessa forma, a gestão da demanda acaba por não ser amplamente conhecida, e, por conseqüência, torna-se sub-utilizada nas organizações. Assim, este trabalho visa colaborar para a solução dessa questão, contribuindo para a geração de um modelo formal que possa ser útil tanto à comunidade acadêmica quanto à empresarial interessada. / In current context of the Manufacturing Planning and Control Systems there is a need for a better use of the business process that address the development of alI its plans, the Demand Management process. The existence of appropriate literature and models or formalisms that aims to help a better understanding and usage of this business process is rare and insufficient. ln that way, the Demand Management process is not being known thoroughly and, for consequence, it is not properly used in some organizations. Thus, this work aims to collaborate for the solution of this problem, contributing to a formal model generation that can be useful for the academic and managerial community interested.

In order to make company work efficiently, managers often divide an enterprise into several functions or departments, such as sales, marketing, human resource, finance and manufacture. However, in this structure, managers would fail to see the wood for the trees. Because each department manager has to be responsible for his own performance, which may easily leads these managers to make decisions that are fit for their department instead of the whole company. Therefore, it¡¦s impossible for companies to make an optimized decision in a dynamic environment. As we enlarge space and time, we can find out that decisions may influence one by another, and the feedback of each decision has a long time delay which makes the manager try to see the wood for the trees even harder. For one manager who tries to show up his performance in a short time will leave the side effect which caused by time delay to other people. What even worse is they can¡¦t predict how much side effect is behind. In this research, we used system dynamics and systems thinking to develop our system dynamics model for the case study. And we developed a MFS(management flight simulator) as a learning tool. Students who manipulate this MFS can enrich their ability to see the wood for the trees. In this case study, we choose a factory which provide electronic product assemble services as a research object. The company was established since AD 1989 until now. After first five years hard working time, it started to grow up stably by keeping changing the product and service. In this industry, success is relied on product quality, price, service and delivery time. Only by making the optimized decision in this competition market can gain better performance. This thesis simulated the case company surface mount technology plant from 1995 to 2006 for 12 years. Students can make different decisions to obtain different equity and capital equipment to evaluate their performance. By different result, simulators can reconsider the structure which is behind the game and their own mental models. After learning from this virtual world, players will find out that their own mental models influencing the final result. From the result and experience, one simulator can accumulate their know-how for the next game. After experiencing this double loop learning process, player will finally learn how to make the best decisions by systems thinking for the real world.

O processo de desenvolvimento de produto é uma atividade caracterizada por um ciclo de projetar-construir-testar que faz uso intensivo do conhecimento existente na empresa. Uma parte dele está armazenada nos documentos gerados no decorrer deste processo, são os conhecimentos explícitos. Este trabalho analisa as soluções computacionais dedicadas a auxiliar na gestão deste tipo de conhecimento e demonstra vários problemas: falta de um modelo conceitual apropriado; limitações referentes aos tipos de conhecimentos armazenados; e falta de uma sistemática de validação e sistematização. Propõe-se um conjunto de elementos, arquitetura, para superá-los, o qual pode ser utilizado como referência para o desenvolvimento de sistemas de gestão de conhecimentos explícitos. A arquitetura foi empregada no desenvolvimento de uma solução computacional específica, utilizando uma ferramenta de modelagem e uma intranet, e esta foi posteriormente aplicada para a gestão dos conhecimentos dentro de um grupo de pesquisa. Os resultados demonstram que a arquitetura é viável e que o sistema pode e deve ser aplicado em empresas que desenvolvam produtos. Encerra-se o trabalho apresentando as propostas de melhoria e de novas avaliações para ambas, a arquitetura e a solução desenvolvidas / The product development is characterized by a continuing design-build-test cycle, marked by experimentation and the intensive use of enterprise knowledge. Part of them is tangible and is stored in the documents created during the product development process, named explicit knowledge. This work analyzes the computational solutions for support the explicit knowledge management. As result present a set of common limitations of commercial tools applied in this area. Three important aspects are: a lack of conceptual model to link the information systems at knowledge management effort; small knowledge representation types manipulated by these systems; and a lack of knowledge validation model, sufficient to "filter" the explicit knowledge created. For encompass these challenges, this work presents an architecture (a set of elements) designed to build explicit knowledge management systems. A solution aided by the architecture was created, which integrates a commercial modeling tool and an intranet especially designed.

Die Arbeit adressiert insgesamt drei Forschungsschwerpunkte. Der erste Schwerpunkt setzt sich mit zu entwickelnden BPMN-Erweiterungen auseinander und stellt deren methodische Implikationen im Rahmen der bestehenden Sprachstandards dar. Dies umfasst zum einen ganz konkrete Spracherweiterungen wie z. B. BPMN4CP, eine BPMN-Erweiterung zur multi-perspektivischen Modellierung von klinischen Behandlungspfaden. Zum anderen betrifft dieser Teil auch modellierungsmethodische Konsequenzen, um parallel sowohl die zugrunde liegende Sprache (d. h. das BPMN-Metamodell) als auch die Methode zur Erweiterungsentwicklung zu verbessern und somit den festgestellten Unzulänglichkeiten zu begegnen. Der zweite Schwerpunkt adressiert die Untersuchung von sprachunabhängigen Fragen der Erweiterbarkeit, welche sich entweder während der Bearbeitung des ersten Teils ergeben haben oder aus dessen Ergebnissen induktiv geschlossen wurden. Der Forschungsschwerpunkt fokussiert dabei insbesondere eine Konsolidierung bestehender Terminologien, die Beschreibung generisch anwendbarer Erweiterungsmechanismen sowie die nutzerorientierte Analyse eines potentiellen Erweiterungsbedarfs. Dieser Teil bereitet somit die Entwicklung einer generischen Erweiterungsmethode grundlegend vor. Hierzu zählt auch die fundamentale Auseinandersetzung mit Unternehmensmodellierungssprachen generell, da nur eine ganzheitliche, widerspruchsfreie und integrierte Sprachdefinition Erweiterungen überhaupt ermöglichen und gelingen lassen kann. Dies betrifft beispielsweise die Spezifikation der intendierten Semantik einer Sprache.

There is a growing need to study factors that affect user comprehension of Business Process Management (BPM) information portrayed by graphical process models (GPMs). For example, deployment of BPM Systems, unique types of enterprise-level information systems, has dramatically increased in recent years. This increase is primarily because BPM Systems give a variety of managers across an enterprise the ability to directly design, configure, enact, monitor, diagnose, and control business processes that other types of enterprise systems do not. This is possible because BPM Systems uniquely rely on GPMs derived from formal graph theory. Besides controlling the business processes, these GPMs, such as metagraphs and Unified Modeling Language (UML) diagrams, portray business process information (BPI) and prompt BPM managers to apply their training and expertise to deal with BPM situations. As a result, GPMs are the primary information artifacts for decision-making and communication among different, often geographically dispersed stakeholders. Therefore, user comprehension of these unique GPMs is critical to the efficient and effective development, deployment, and utilization of BPM Systems. User comprehension outcomes are jointly affected by the (1) BPM cognitive resources available to each manager (including the type of GPM, BPI, and user educational training and experience), and (2) cognitive differences between individual BPM managers (such as their mental workload, cognitive styles and cognitive abilities). Although research has studied GPMs in various contexts, there is apparently no empirical research investigating GPM user comprehension in the context of BPM Systems. This research makes an important contribution by addressing this gap in the literature. Statement of the Objective: The purpose of this research is to empirically study how BPM cognitive resources and cognitive differences between individuals affect outcomes of GPM user comprehension. This research centered on the following objectives: A. Investigate whether more positive user comprehension outcomes are produced by novice users if a single GPM technique is used to portray different types of BPI (e.g., as with metagraphs) or if different GPM techniques are used to portray different types of BPI (e.g., as with UML diagrams). B. Investigate whether one type of BPI is more easily comprehended and interpreted by novice users irrespective of the type of GPM or the type of educational training of the user. C. Investigate whether users with a specific type of user educational training can more easily comprehend and interpret BPM information irrespective of the type of GPM or the type of BPI. D. Evaluate influences of individual cognitive differences (i.e., mental workload, cognitive styles, and cognitive abilities) on outcomes of user comprehension. In order to accomplish these objectives, this study: (a) defined a theoretical framework conceptualizing user comprehension outcomes in terms of the interaction between cognitive resources external to the user and individual differences affecting how users cognitively process BPI, (b) empirically tested an operational research model of GPM user comprehension that is based on the theoretical framework, and (c) interpreted the experimental results in the context of related literatures. Description of Research Methods: This study empirically tested relationships between several variables representing BPM cognitive resources and individual cognitive differences hypothesized as influencing the outcomes of user comprehension. A laboratory experiment, involving 87 upper-level undergraduate students from two universities, analyzed relationships between participant comprehension of two types of GPMs (i.e., metagraphs and UML diagrams) used to portray three types of BPI (i.e., task-centric, resource-centric, and information-centric BPI) by novice GPM users possessing different educational training (i.e., industrial engineering, business management, and computer science training). Dependent variables included assessments of task accuracy, task timeliness, subjective mental workload, and self-efficacy. Covariate effects were also analyzed for two types of participant cognitive abilities (i.e., general cognitive ability (GCA) and attentional abilities) and two types of participant cognitive styles (extroversion-introversion and sensing-intuitive). Multivariate analysis techniques were used to analyze and interpret the data. Discussion of Results: The type of GPM and participants' GCA produced significant effects on the dependent variables in this study. For example, metagraph users produced significantly more desirable results than UML users across all dependent variables, contrary to what was hypothesized. However, if only the BPM cognitive resources (i.e., GPM Type, BPM Type, and the Type of Participant Education) were studied in relation to user comprehension outcomes, spurious conclusions would have been reached. When individual cognitive differences were included in the research model and analyses, results showed participants with higher GCA produced significantly more positive user comprehension outcomes compared to participants with lower GCAs. Also, many of the impacts of differences in the types of BPI and the types of UET were moderated by the differences in participants' GCA and attentional abilities. In addition, the relationship between subjective mental workload and task performance (i.e., accuracy and timeliness) suggest a possible GPM cognitive "profile" for user comprehension tasks in a BPM Systems context. These results have important implications for future research and practice in several bodies of knowledge, including GPM user comprehension in management systems engineering, BPM modeling, BPM Systems, HCI, and cognitive ergonomics literature. / Ph.
