Die Entwicklung kostengünstiger, energiesparender und resourcenschonender Produkte gewinnt zunehmend an Bedeutung. Dabei bildet die Bewertung von Kosten und Energie über den gesamten Lebenszyklus des Produkts, von der Entwicklung und Fertigung über den Betrieb bis hin zum Recycling, auf Basis virtueller Prototypen eine wesentliche Grundlage. Da Entwurfsentscheidungen in frühen Phasen der Entwicklung, in denen noch kein realer Prototyp existiert, einen hohen Einfluss auf spätere Kosten haben können, besteht die Notwendigkeit empirische, entscheidungsrelevante Daten aus IT-Systemen der Produktentwicklung (z.B. Produktdatenmanagementsysteme) und des Betriebs (z.B. Enterprise-Resource-Planning-Systeme) zu extrahieren und dem Konstrukteur geeignete Methoden zur Aggregation der Daten bereitzustellen. Insbesondere bei der Optimierung hinsichtlich der Energieeffzienz von Produkten muss auf Daten des gesamten Lebenszyklus zurückgegriffen werden, um schon in der Entwicklungsphase Abschätzungen über den Energieverbrauch im Produktleben treffen zu können. Eine Optimierung der Energieeffizienz kann dabei sowohl durch die Steigerung der Produktivität bei gleichbleibendem Energieverbrauch als auch durch die Verringerung des Energieverbrauchs bei gleichbleibender Produktivität erfolgen. In diesem Bericht soll der Produktentwicklungsprozess aus IT-Sicht betrachtet werden, indem zunächst aktuelle Methodiken der Produktentwicklung mit ihrer IT-Unterstützung und der beteiligten IT-Systeme untersucht werden. Es werden Anforderungen an ein IT-System formuliert, die Energieeffizienzbewertungen und -optimierungen in allen Phasen der Produktentwicklung unter Nutzung der beteiligten IT-Systeme ermöglichen. Ein solches IT-System zur energiesensitiven Produktentwicklung (energiesensitives Produktentwicklungssystem) soll den Konstrukteur bei der Entwicklung energieeffizenter Produkte unterstützen. Dafür müssen die Funktionalitäten bestehender PDM-Systeme um Methoden zur Analyse, Synthese und Bewertung der Energieeffizienz des Produkts erweitert werden. Es wird abschließend vorgeschlagen, wie die Methoden zur Bewertung energierelevanter Daten durch Workflows umgesetzt werden können.

Las organizaciones que brindan servicios informáticos para el desarrollo de proyectos de investigación académica no están utilizando Enterprise Content Management (ECM), a pesar de la complejidad de la administración de documentos asociados a esta actividad. ECM permite para almacenar, entregar y gestionar contenido de forma más ágil y así poder brindar mejor servicio. En este trabajo se propone un modelo de gestión documental donde se presentan las fases que permiten implementar esta tecnología y con ello ganar capacidades nuevas en la organización. Para validar el modelo se implementó una herramienta en 2 empresas virtuales analizando los tiempos de respuesta a las solicitudes de servicio que se producían antes y después de la implementación. Además, se hizo una encuesta utilizando la escala de Likert para medirá la satisfacción de los stakeholders. / Organizations that provide computer services for the development of academic research projects are not using Enterprise Content Management (ECM), despite the complexity of document management associated with this activity. ECM allows to store, deliver and manage content more agile and thus be able to provide better service. In this paper, a document management model is proposed where the phases that allow implementing this technology are presented and thereby gain new capabilities in the organization. To validate the model, a tool was implemented in 2 virtual companies analyzing the response times to service requests that occurred before and after implementation. In addition, a survey was made using the Likert scale to measure stakeholder satisfaction. / Tesis

Die Diplomarbeit entstand im Kontext der Projekte HematoWork bzw. AgentWork. Inhalt dieser Projekte ist die computerbasierte Unterstützung von medizinischen Arbeitsabläufen. Dazu wird ein Workflow-Management-System erstellt, welches insbesondere solche Arbeitsabläufe unterstützt, die dynamisch zur Laufzeit an sich ändernde Umgebungsbedingungen angepasst werden müssen. Der im Rahmen der Arbeit konzeptionierte und prototypisch implementierte Workflow-Editor ist eine Komponente des Workflow-Systems. Er ermöglicht die Erstellung von Arbeitsablaufplänen (Workflow-Definitionen) mittels einer grafischen Oberfäche. Wesentliche Inhalte der Arbeit sind dabei unter anderem die Vorstellung eines Workflow-Modells, welches speziell dynamische Änderungen zur Laufzeit ermöglicht, und ein Verifikationsalgorithmus, der die Korrektheit erstellter Workflow-Definitionen prüft.

Das Thema Workflow-Management hat in den letzten Jahren ein beständig steigendes Interesse aus Forschung und Anwendung erfahren. Weit über 100 Anbieter haben eine Vielzahl von Workflowprodukten auf den Markt gebracht, deren unterschiedliche Ansätze eine gemeinsame Betrachtung erschweren. Die vorliegende Arbeit will einen Überblick über den erreichten Stand auf dem Forschungsgebiet Workflow-Management geben und untersuchen, inwieweit sich die gewonnenen Erkenntnisse in den Produkten wiederfinden. Besondere Beachtung findet dabei die Frage, ob die Produkte neue Informationsinseln darstellen oder Interaktionen mit anderen Anwendungen, speziell anderen Workflow-Management-Systemen, möglich sind.

In dieser Arbeit wird ein Ansatz zur automatischen Berechnung und Ausführung von strukturellen Anpassungsmöglichkeiten für Workflows auf Basis von Kontextinformationen entwickelt. Zur Sicherstellung der semantischen Korrektheit der Anpassungsmöglichkeiten werden zwei Arten von Einschränkungen berücksichtigt: Zustandsbezogene Einschränkungen (ZBE) und Aktivitätsabhängigkeiten (AA). ZBEs spezifizieren Einschränkungen zwischen Anpassungsoperationen und dem Ausführungszustand des Workflows. AAs beschreiben temporale Beziehungen zwischen Aktivitäten eines Workflows.

As forças motrizes por trás da adoção e do desenvolvimento de um WfMS são aplicações científicas e de negócios. Esforços conjuntos de ambos resultaram em mecanismos consolidados, além de padrões e protocolos consensuais. Em particular, um WfMS científico (SWfMS -- \textit{Scientific WfMS}) auxilia cientistas a especificar e executar experimentos distribuídos. Ele fornece diferentes recursos que suportam atividades em um ambiente experimental, como prover flexibilidade para mudar o projeto de workflow, manter a proveniência e suportar reproducibilidade de experimentos. Por outro lado, apesar de poucas iniciativas de pesquisa, WfMSs não fornecem suporte apropriado à personalização dinâmica e baseada em contexto durante a execução; adaptações em tempo de execução normalmente requerem intervenção do usuário. Esta tese se concentra em superar essa deficiência, fornecendo a WfMSs um mecanismo de ciente do contexto para personalizar a execução de workflows. Como resultado, foi projetado e desenvolvido o DynFlow -- uma arquitetura de software que permite tal personalização aplicada a um domínio: planejamento de saúde. Este domínio foi escolhido por ser um ótimo exemplo de personalização sensível ao contexto. Procedimentos de saúde constantemente sofrem mudanças que podem ocorrer durante um tratamento, como a reação de um paciente a um medicamento. Para suprir a demanda, a pesquisa em planejamento de saúde desenvolveu técnicas semi-automáticas para suportar mudanças rápidas dos passos de fluxos de tratamento, de acordo com o estado e a evolução do paciente. Uma dessas técnicas é \textit{Computer-Interpretable Guidelines} (CIG), cujo membro mais proeminente é \textit{Task-Network Model} (TNM) -- uma abordagem baseada em regras capaz de construir um plano em tempo de execução. Nossa pesquisa nos levou a concluir que CIGs não suportam características necessárias por profissionais de saúde, como proveniência e extensibilidade, disponíveis em WfMSs. Em outras palavras, CIGs e WfMSs têm características complementares e são direcionadas à execução de atividades. Considerando os fatos citados, as principais contribuições desta tese são: (a) especificação e desenvolvimento do DynFlow, cujo modelo associa características de TNMs e WfMS; (b) caracterização das principais vantagens e desvantagens de modelos CIGs e WfMSs; (c) implementação de um protótipo, baseado em ontologias e aplicadas ao domínio da saúde e enfermagem / Abstract: Workflow Management Systems (WfMS) are used to manage the execution of processes, improving efficiency and efficacy of the procedure in use. The driving forces behind the adoption and development of WfMSs are business and scientific applications. Associated research efforts resulted in consolidated mechanisms, consensual protocols and standards. In particular, a scientific WfMS helps scientists to specify and run distributed experiments. It provides several features that support activities within an experimental environment, such as providing flexibility to change workflow design and keeping provenance (and thus reproducibility) of experiments. On the other hand, barring a few research initiatives, WfMSs do not provide appropriate support to dynamic, context-based customization during run-time; on-the-fly adaptations usually require user intervention. This thesis is concerned with mending this gap, providing WfMSs with a context-aware mechanism to dynamically customize workflow execution. As a result, we designed and developed DynFlow ¿ a software architecture that allows such a customization, applied to a specific domain: healthcare planning. This application domain was chosen because it is a very good example of context-sensitive customization. Indeed, healthcare procedures constantly undergo unexpected changes that may occur during a treatment, such as a patient¿s reaction to a medicine. To meet dynamic customization demands, healthcare planning research has developed semi-automated techniques to support fast changes of the careflow steps according to a patient¿s state and evolution. One such technique is Computer-Interpretable Guidelines (CIG), whose most prominent member is the Task-Network Model (TNM) -- a rule based approach able to build on the fly a plan according to the context. Our research led us to conclude that CIGs do not support features required by health professionals, such as distributed execution, provenance and extensibility, which are available from WfMSs. In other words, CIGs and WfMSs have complementary characteristics, and both are directed towards execution of activities. Given the above facts, the main contributions of the thesis are the following: (a) the design and development of DynFlow, whose underlying model blends TNM characteristics with WfMS; (b) the characterization of the main advantages and disadvantages of CIG models and workflow models; and (c) the implementation of a prototype, based on ontologies, applied to nursing care. Ontologies are used as a solution to enable interoperability across distinct SWfMS internal representations, as well as to support distinct healthcare vocabularies and procedures / Doutorado / Ciência da Computação / Doutor em Ciência da Computação

Dynamic changes in the business environment requires their business process to be up-to-date. The Workflow Management Systems supporting these business processes need to adapt to these changes rapidly. The Work Flow Management Systems however lacks the ability to dynamically propagate the process changes to their process model schemas (Workflow templates). The literature on workflow schema evolution emphasizes the impact of changes in control flow with very ittle attention to other aspects of a workflow schema. This thesis studies the data aspect (data flow and data model) of workflow schema during its evolution. Workflow schema changes can lead to inconsistencies between the underlying database model and the workflow. A rather straight forward approach to the problem would be to abandon the existing database model and start afresh. However this introduces data persistence issues. Also there could be significant system downtimes involved in the process of migrating data from the old database model to the current one. In this research we develop an approach to address this problem. The business changes demand various types of control flow changes to its business process model (workflow schema). The control flow changes include task insertion, deletion, swapping, movement, replacement, extraction, in-lining, Parallelizing etc. Many of the control flow changes to the workflow can be made by using the combination of a simple task insertion and deletion, while some like embedding task in loop/ conditional branch and Parallelizing tasks also requires the addition/removal of control dependency between the tasks. Since many of the control flow change patterns involves task insertion and deletion at its core, in this thesis we study its impact on the underlying data model. We propose algorithms to dynamically handle the changes in the underlying relational database schema. First we identify the basic change patterns that can be implemented using atomic task insertion and deletions. Then we characterize these basic pattern in terms of their data flow anomalies (Missing, Redundant, Conflicting data) that they can generate. The Data schema compliance criteria are developed to identify the data changes: (i) that makes the underlying database schema inconsistent with the modified workflow and (ii) generating the aforementioned data anomalies. The Data schema compliance criteria characterizes the change patterns in terms of its ability to work with the current relational data model. The Data schema compliance criteria show various properties required of the modified workflow to be consistent with the underlying database model. The data of any workflow instance conforming to Data schema compliance criteria can be directly accommodated in the database model. The data anomalies (of task insertion and deletion) identified using DSC are handled dynamically using respective Data adaptation algorithms. The algorithm uses the functional dependency constraints in the relational database model to adapt/handle these data anomalies. Such handled data (changes) that conform to DSC can be directly accommodated in the underlying database schema. Hence with this approach the workflow can be modified (using task insertion and deletion) and their data changes can be implemented on-the-fly using the Data adaptation algorithms. In this research the same old data model is evolved without abandoning it even after the modification of the workflow schema. This maintains the old data persistence in the existing database schema. Detailed implementation procedures to deploy the Data adaptation algorithms are presented with illustrative examples.
