    Interorganisationale Workflows sind Arbeitsabläufe, welche die Grenzen einer Organisation verlassen und einen Rahmen für Kooperationen der verschiedenen autonomen Organisationen zur Verfügung stellen. Ein wichtiger Punkt für den Entwurf solcher Workflows ist die Balance zwischen Offenheit und Abgrenzung, wobei erstere für Kooperationen und letztere die für den Schutz von Know-how benötigt wird. Workflow Sichten stellen ein effizientes Werkzeug für diesen Zweck zur Verfügung. Durch Offenlegung von bestimmten Teilen eines Prozesses, können Organisationen sowohl kooperieren als auch das Know-how schützen. Diese Dissertation präsentiert nun eine Methode für die korrekte Konstruktion von Workflow Sichten. Es wird angenommen, dass Organisationen Web Service orientierte Technologien zur Modellierung und Implementierung von interorganisationalen Workflows verwenden. Die Anwendung von Web Services bietet Organisationen viele Vorteile. Den eigentlichen Mehrwert von Web Services stellt aber die Kompositionsfähigkeit dar. Verfügbare Web Services können dadurch von anderen Choreographien und Orchestrationen (wieder-)verwendet werden. Die Notwendigkeit der Implementierung von Systemen von Null weg kann minimiert werden. Die zentralen Anforderungen sind einerseits eine Architektur mit adäquatem Potential, andererseits die Verifikation der Korrektheit. Diese Dissertation präsentiert nun eine Architektur zur Modellierung von Web Service Composition basierten interorganisationalen Workflows, genannt föderierte Choreographien, die verglichen mit anderen Architekturen verschiedene Vorteile anbieten. Darüber hinaus werden Algorithmen und Techniken zur Verifikation der strukturellen und temporalen Korrektheit vorgestellt. Strukturelle Korrektheit prüft, ob die Strukturen der beteiligten Prozesse zusammenpassen. Temporale Korrektheit überprüft, ob ein interorganisationaler Workflow, der aus mehreren Choreographien und Orchestrationen besteht hinsichtlich der lokalen und globalen Bedingungen fehlerfrei ist. Mit Hilfe dieser Techniken kann die strukturelle und temporale Konformität des Modells zur Designzeit überprüft werden. Falls das Modell nicht strukturell oder temporal konform ist, können nötige Änderungen durchgeführt werden, sodass die korrekte Ausführung zur Laufzeit garantiert werden kann. Die Überprüfung der Konformität zur Designzeit reduziert die Prozesskosten vor allem wegen den folgenden zwei Gründen: Erstens, die entdeckten Fehler zur Designzeit sind normalerweise billiger als jene, die zur Laufzeit entdeckt werden und zweitens, Fehlerbehandlungsmechanismen können verhindert werden, die wiederum Zusatzkosten verursachen. Zusätzlich zu der vorgestellten Architektur wird eine allgemeinere Architektur zusammen mit den passenden Konformitätsprüfungsalgorithmen präsentiert. Der Ansatz ist Platform- und sprachunabhängig und die Algorithmen sind verteilt.Interorganizational workflows are workflows that cross the boundaries of a single organization and provide a framework for cooperation of different autonomous organizations. An important issue when designing such workflows is the balance between the openness needed for cooperation and the privacy needed for protection of business know-how. Workflow views provide an efficient tool for this aim. By exposure of only selected parts of a process, organizations can both cooperate and protect their business logic. This dissertation presents a technique for a correct construction of workflow views. It is assumed that organizations and partners use web services and web service related technology to model and implement interorganizational workflows. Application of web services offers several advantages for organizations. The real surplus of web services is their capability of being composed to more complex systems. Available web services can be reused by other choreographies and orchestrations and the need for development of new systems from scratch can be minimized. The essential requirements are on the one hand an architecture with adequate capabilities and on the other hand, verification of correctness. This dissertation proposes an architecture for modeling web service composition based interorganizational workflows, called \emph{federated choreographies}, that provides several advantages compared to existing proposals. Moreover, algorithms and techniques for verification of structural and temporal correctness of interorganizational workflows are proposed. Structural conformance checks if the structures of the involved processes match. Temporal conformance checks if an interorganizational workflow composed of choreographies and orchestrations is temporally error-free with respect to local and global temporal constraints. The proposed algorithms can be applied for checking the structural and temporal conformance of the federated choreographies at design-time. If the model is not structurally or temporally conformant, necessary modifications can be done such that the correct execution of the flow at run-time can be guaranteed. The conformance checking at design time reduces the cost of process because of two reasons: first, errors detected at design time are normally cheaper than those detected at run time and second, exception handling mechanisms can be avoided which are, in turn, coupled with additional costs. In addition to the proposed architecture, a more general architecture together with the conformance checking algorithms and techniques for interorganizational workflows are presented. The presented approach is language and platform independent and algorithms work in a distributed manner

    Semantic discovery and reuse of business process patterns

    Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

    Modelagem e simulação de sistemas de gerenciamento de processos de negócios baseadas em workflow net temporais com mecanismos de alocação de recursos híbridos fuzzy

    The main objective of this doctoral research is to propose a new business process model for efficient (and realistic) resources and time management in Workflow nets. This research had as its starting point the validation of the fuzzy resource allocation model presented in (JESKE, 2006). In particular, a specialized inference mechanism of the token player type adapted to a fuzzy hybrid resource allocation model was implemented in the modeling, analysis and simulation tool of colored Petri nets called CPN Tools. Such simulations have shown that the new model in relation to a simple resource allocation mechanism with an earlier firing policy (FIFO) allows an improvement in the proportion of cases that meet the established deadlines. To solve the scheduling problem in Workflow Management Systems, important characteristics inherent to these systems should be considered. In particular, when many cases are run concurrently, conflict situations due to shared resource can occur and must be resolved in real time (without a backward mechanism). Also, temporary restrictions regarding the deadlines for delivery of specific cases should be considered. For that, a fuzzy time associated to the activities of the processes was defined as well as a mechanism of propagation of restrictions whose role is to guarantee the consistency of the time constraints to carry out the activities respecting the expected delivery times. With the objective of making the behavior of the new model the closest and consistent with the behavior of the human collaborators involved in the execution of business process activities, the notion of joint possibility was inserted in the model. This notion involves the uncertain and nebulous character of the execution times of the activities of the processes and the intensity of the resources used to carry out the activities. New firing rules for transitions were then defined based on the concept presented. Token players based on the new model presented were defined, implemented, simulated and validated in the CPN Tools, whose main role is to show the execution of the new models presented. Using the CPN Tools, it was possible to evaluate the system behavior considering the expected or most critical operating. It is important to point out that through the simulation results it is possible to predict how the system will behave and, from this, to evaluate several possible resource distribution scenarios in order to be able, in the future, to carry out the sizing of the system based on a modeling and simulation tool that approximates of the way employees work in an office environment.Tese (Doutorado)O principal objetivo desta pesquisa de doutorado é propor um novo modelo de processo de negócios para uma gestão eficiente (e realista) dos recursos e do tempo em Workflow nets. Esta pesquisa teve como ponto de partida a validação do modelo de alocação de recursos fuzzy apresentado em (JESKE, 2006). Em particular, um mecanismo de inferência especializado do tipo token player adaptado a um modelo de alocação de recurso híbrido fuzzy foi implementado na ferramenta de modelagem, análise e simulação de redes de Petri coloridas chamada CPN Tools. Tais simulações mostraram que o novo modelo em relação a um mecanismo simples de alocação de recurso com uma política de disparo mais cedo (FIFO) permite uma melhoria da proporção de casos que respeitam os prazos estabelecidos. Para resolver o problema do escalonamento em Sistemas de Gerenciamento de Workflow deverão ser consideradas características importantes inerentes a estes sistemas. Em particular, quando muitos casos são executados simultaneamente, situações de conflito por recursos compartilhados podem ocorrer e devem ser resolvidas em tempo real (sem um mecanismo de retrocesso). Também, deverão ser consideradas restrições temporais relativas aos prazos de entrega de casos específicos. Para tanto, definiu-se um tempo fuzzy associado às atividades dos processos bem como um mecanismo de propagação de restrições cujo papel é garantir a consistência das restrições de tempo para realização das atividades respeitando os prazos de entrega previstos. Com o objetivo de tornar o comportamento do novo modelo o mais próximo e consistente com o comportamento de funcionários humanos envolvidos na execução de atividades de processos de negócios, a noção de possibilidade conjunta que envolve o caráter incerto e nebuloso tanto dos tempos de execução das atividades dos processos quanto das intensidades de carga dos recursos utilizados para a realização de atividades foi inserida no modelo. Novas regras de disparo de transições foram então definidas baseadas no conceito apresentado. Jogadores de rede de Petri do tipo token player baseados no novo modelo apresentado foram definidos, implementados, simulados e validados na ferramenta CPN Tools, cujo papel principal é mostrar a execução dos novos modelos apresentados. Com o uso da ferramenta CPN Tools foi possível avaliar o comportamento do sistema em funcionamento esperado ou em situação mais crítica. É importante salientar que através dos resultados de simulação é possível prever como o sistema se comportará, isso a fim de avaliar diversos cenários possíveis de distribuição de recursos para poder, no futuro, realizar o dimensionamento do sistema baseado numa ferramenta de modelagem e simulação próxima da forma de trabalhar dos funcionários em ambiente de escritório
