Available in PDF, EPUB and Kindle. Book excerpt: We introduce the notion, issues, and challenges of dynamic coalition formation (DCF) among rational software agents in open, heterogeneous and work widely distributed environments such as the Internet and Web. Selected relevant approaches coping with only parts of the DCF problem domain in different disciplines such as decision theory, social reasoning, and machine learning are briefly discussed. Finally, we sketch one novel DCF scheme, and highlight some future research work towards a general framework of dynamic coalition formation.

This book was released on 2016-09-16 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dynamic Coalitions denote a temporary collaboration between different entities to achieve a common goal. A key feature that distinguishes Dynamic Coalitions from static coalitions is Dynamic Membership, where new members can join and others can leave after a coalition is set. This thesis studies workflows in Dynamic Coalitions, by analyzing their features, highlighting their unique characteristics and similarities to other workflows, and investigating their relation with Dynamic Membership. For this purpose, we use the formal model of Event Structures and extend it to faithfully model scenarios taken as use cases from healthcare. Event Structures allow for workflows modeling in general, and for modeling Dynamic Membership in Dynamic Coalitions as well through capturing the join and leave events of members. To this end, we first extend Event Structures with Dynamic Causality to address the dynamic nature of DCs. Dynamic Causality allows some events to change the causal dependencies of other events in a structure. Then, we study the expressive power of the resulting Event Structures and show that they contribute only to a specific kind of changes in workflows, namely the pre-planned changes. Second, we present Evolving Structures in order to support ad-hoc and unforeseen changes in workflows, as required by the use cases. Evolving Structures connect different Event Structures with an evolution relation which allows for changing an Event Structure during a system run. We consider different approaches to model evolution and study their equivalences. Furthermore, we show that the history of a workflow should be preserved in our case of evolution in Dynamic Coalitions, and we allow for extracting changes from an evolution to support Process Learning. Third, to capture the goals of DCs, we equip Evolving Structures with constraints concerning the reachability of a set of events that represents a goal. The former extensions allow for examining the changes and evolutions caused by members, and examining members’ contributions to goal satisfaction, through their join and leave events. Finally, we highlight many modeling features posed as requirements by the domain of our Dynamic-Coalition use cases, namely the healthcare, which are independent from the nature of Dynamic Coalitions, e.g. timing. We examine the literature of Event Structures for supporting such features, and we identify that the notion of Priority is missing in Event Structures. To this end, we add Priority to various kinds of Event Structures from the literature. Furthermore, we study the relation between priority on one side, and conjunctive causality, disjunctive causality, causal ambiguity and various kinds of conflict on the other side. Comparing to Adaptive Workflows, which are concerned with evolutions of workflows that occur as a response to changes, e.g. changes in the business environment or exceptions, this thesis shows that Dynamic-Coalition workflows are not only Adaptive but also Goal-Oriented. Besides, it adds one extra trigger for evolution in workflows—unique to Dynamic Coalitions—namely the join of new members who contribute to goal satisfaction in a Dynamic Coalition. Finally the thesis contributes to bridging the gap in modeling between theory and domain experts by supporting step-by-step modeling applied regularly in healthcare and other domains. Dynamische Koalitionen (DKen) bezeichnen eine temporäre Kollaboration zwischen verschiedenen Entitäten zum Erreichen eines gemeinsamen Ziels. Ein Schüsselaspekt, welcher dynamische Koalitionen von statischen Koalitionen unterscheidet ist die dynamische Mitgliedschaft, durch die neue Mitglieder hinzu- kommen und andere die Koalitionen verlassen können, nachdem sie entstanden ist. Diese Arbeit studiert Workflows in dynamische Koalitionen durch eine Analyse ihrer Eigenschaften, das Herausstellen ihrer einzigartigen Charakteristika und Ähnlichkeiten zu anderen Workflows und durch eine Untersuchung ihrer Beziehung zu dynamischer Mitgliedschaft. In diesem Sinne nutzen wir das formales Model der Ereignisstukturen (ESen) und erweitern es, um Fallstudien aus der Medizin angemessen zu modellieren. ESen erlauben sowohl eine generelle Workflow Modellierung als auch eine Darstellung von Eintritt- und Austrittereignissen von Mitgliedern. Zu diesem Zweck erweitern wir ESen zuerst um Dynamische Kausalität, um die dynamische Natur von DKs abzubilden. Dynamische Kausalität erlaubt bestimmten Ereignissen die kausalen Abhängigkeiten anderer Ereignissen in einer Struktur zu verändern. Dann untersuchen wir die Ausdrucksstärke der resutierenden ESen und zeigen, dass sie nur eine spezifische Art der Veränderung abbilden, die sogenannten vorgeplanten Veränderungen. Als Zweites präsentieren wir Evolving in ESen um ad-hoc- und unvorhergesehene Veränderungen zu unterstützen, wie es durch unsere Fallstudien benötigt wird. Evolving in ESen verbinden verschiedene ESen mit einer Relation, welche eine Veränderung einer ES während eines Ablaufes erlaubt. Wir ziehen verschiedene Ansätze der Modelevolution in Betracht und untersuchen ihre Äquivalenzen. Des Weiteren zeigen wir, dass in unserem Fall der Evolution in DKen die Geschichte eines Workflows erhalten bleiben muss und wir ermöglichen das Extrahieren von Veränderungen einer Evolution, um Process Learning zu unterstützen. Drittens: Um die Ziele von DKen abzubilden, fügen wir den Evolving in ESen mit Einschränkungen bezüglich der Erreichbarkeit einer Menge von Ereignissen hinzu, welche das Ziel repräsentieren. Die genannten Erweiterungen erlauben es sowohl die Änderungen und Evolutionen, die vom Mitgliedern verursacht werden als auch die Beiträge der Mitglieder zur Zielerreichung durch deren Entritt- und Austrittereignissen zu untersuchen. Schlussendlich, stellen wir viele Modellierungseigen- schaften dar, welche von den DK-Fallstudien aus der Medizin benötigt werden und unabhängig von der Natur der DKen sind, wie z.B. Timing. Wir untersuchen die Literatur zu ESen bezüglich Unterstützung für solche Eigenschaften und stellen fest, dass der Begriff Priorität in ESen fehlt. Daher fügen wir Priorität zu verschiedenen ESen aus der Literatur hinzu. Des Weiteren untersuchen wir die Beziehungen von Priorität auf zu Konjunktiver Kausalität, disjunktiver Kausalität, kausal Uneindeutigkeit und verschiedenen Formen von Konflikt. Im Vergleich zu Adaptive Workflows, welche sich mit der Evolution von Workflows beschäftigt, die als Reaktion auf Veränderungen entsteht, wie z.B. Veränderungen im Business Environment oder Exceptions, zeigt diese Arbeit das DKen nicht nur adaptiv sondern auch zielorientiert sind. Außerdem fügt sie einen zusätzlichen Auslöser für Evolution in Workflows hinzu, welcher ausschließlich DKen eigen ist: das Hinzukommen neuer Mitglieder welche zur Ziel- erreichung der DK beitragen. Zuletzt trägt diese Arbeit bei, die Lücke der Modellierung zwischen der Theorie und den Domänenexperten zu überbrücken, in dem sie eine Schritt-für-Schritt Modellierung unterstützt, welche regelmäßig in der Medizin und anderen Bereichen angewand wird.

This book was released on 2006-06-03 with total page 367 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is the first joint working conference between the IFIP Working Groups 11. 1 and 11. 5. We hope this joint conference will promote collaboration among researchers who focus on the security management issues and those who are interested in integrity and control of information systems. Indeed, as management at any level may be increasingly held answerable for the reliable and secure operation of the information systems and services in their respective organizations in the same manner as they are for financial aspects of the enterprise, there is an increasing need for ensuring proper standards of integrity and control in information systems in order to ensure that data, software and, ultimately, the business processes are complete, adequate and valid for intended functionality and expectations of the owner (i. e. the user organization). As organizers, we would like to thank the members of the international program committee for their review work during the paper selection process. We would also like to thank the authors of the invited papers, who added valuable contribution to this first joint working conference. Paul Dowland X.

This book was released on 2010-10-06 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the proceedings of the Third International DMTF Academic Alliance Workshop on Systems and Virtualization Management: Standards and the Cloud (SVM 2009) held in Wuhan, China, during September 22-23, 2009. The SVM 2009 proceedings are intended for use by students of systems and vir- alization management. The reader is presumed to have a basic knowledge of systems management technologies and standards at the level provided, for example, by the Common Information Model (CIM) standard for modeling management resources. The student of systems management will find here material that could be included in an advanced study program. These proceedings should furthermore allow students to acquire an appreciation of the breadth and variety of systems and virtualization m- agement research. The proceedings also illuminate related standards and research issues, answering questions such as: what are the implications of virtualization for distributed systems management, which advances in information models and protocols aid in managing virtualization, what new problems will we incur when managing virtualized systems and services, and how might management itself benefit from virtualization? Topics related to managing distributed systems, virtualization of distributed - sources/services and work in management standardization are also highlighted. There were 28 regular paper submissions. These went through an active review process, with each submission reviewed by at least three members of the Program Committee. We also sought external reviews from experts in certain areas. All these inputs were used by the Program Committee in selecting a final program with 12 regular papers.

This book was released on 2012-12-06 with total page 544 pages. Available in PDF, EPUB and Kindle. Book excerpt: Workflow management systems (WFMS) are enjoying increasing popular ity due to their ability to coordinate and streamline complex organizational processes within organizations of all sizes. Organizational processes are de scriptions of an organization's activities engineered to fulfill its mission such as completing a business contract or satisfying a specific customer request. Gaining control of these processes allows an organization to reengineer and improve each process or adapt them to changing requirements. The goal of WFMSs is to manage these organizational processes and coordinate their execution. was demonstrated in the first half The high degree of interest in WFMSs of the 1990s by a significant increase in the number of commercial products (once estimated to about 250) and the estimated market size (in combined $2 billion in 1996. Ensuing maturity product sales and services) of about is demonstrated by consolidations during the last year. Ranging from mere e-mail based calendar tools and flow charting tools to very sophisticated inte grated development environments for distributed enterprise-wide applications and systems to support programming in the large, these products are finding an eager market and opening up important research and development op portunities. In spite of their early success in the market place, however, the current generation of systems can benefit from further research and develop ment, especially for increasingly complex and mission-critical applications.
