“…In this distributed variant of the ADEPT system, we allow WF designers to subdivide a WF schema into several partitions which are then controlled "piecewise" by different WF servers in order to obtain favorable communication behavior. Note that similar approaches have been discussed in literature (Alonso, 1995;Casati, 1996;Cichocki, 2000;Dogac, 1997;Gronemann, 1999;Guth, 1998;Kochut, 2003;Muth, 1998;Schuster, 1999;Sheth, 1997;Weske, 1999).…”

“…Furthermore, completely distributed WfMS, like Exotica/FMQM (Alonso, 1995) and INCAs (Barbará, 1996}, use the machines of the actors as WF servers. Finally, there are approaches for distributed WF management, which do not have a special strategy for distributing the activities to the WF servers; e.g., EVE (Geppert, 1998), METUFlow (Dogac, 1997), MOKASSIN (Gronemann, 1999), WASA 2 (Weske, 1998;Weske, 1999), and the Petri-net based approach presented in (Guth, 1998).…”

This chapter shows how flexibility can be realized for distributed workflows. The capability to dynamically adapt workflow instances during runtime (e.g., to add, delete or move activities) constitutes a fundamental challenge for any workflow management system (WfMS). While there has been significant research on ad-hoc workflow changes and on related correctness issues, there exists only little work on how to provide respective runtime flexibility in an enterprise-wide context as well. Here, scalability at the presence of high loads constitutes an essential requirement, often necessitating distributed (i.e., piecewise) control of a workflow instance by different workflow servers, which should be as independent from each other as possible. This chapter presents advanced concepts and techniques for enabling ad-hoc workflow changes in a distributed WfMS as well. Our focus is on minimizing the communication costs among workflow servers, while ensuring a correct execution behavior as well as correctness of ad-hoc workflow changes at any time.

“…Although executing processes in a peer-to-peer way without involving a centralized component, OSIRIS provides transactional guarantees, following the model of transactional processes [30]. METUFLOW [10] and TransCoop [1] also provide transactional semantics for workflows in a distributed environment.…”

“…In view of these challenges, a number of groups have started new projects (e.g., Infopipes [25], ObjectGlobe [6], ISEE [20], METUFLOW [10] and MARCAs [12], or eFlow [7]) breaking out of conventional technology. At ETH Zurich, the hyperdatabase vision [27,28] was established several years ago with the objective to identify a new middleware infrastructure based on well-understood concepts evolving from database technology.…”

Zusammenfassung. Dieser Beitrag enthält die wesentlichen konzeptionellenÜberlegungen zur Entwicklung eines flexiblen Workflow-Management-Systems. Ausgehend von einer Diskussion möglicher Modellierungsalternativen wird unter Verwendung objektorientierter Modellierungstechniken ein Workflow-Meta-Schema entwickelt, das die relevanten Entitäten klassifiziert und ihre Beziehungen abbildet. Anhand eines Beispiels werden die getroffenen Entwurfentscheidungen ausführlich begründet. Schließlich werden Zustände und Zustandsübergänge von Workflow-Instanzen beschrieben, und es wird diskutiert, wie dynamische Verän-derungen von Workflows zur Laufzeit durchgeführt werden können, um laufende Workflows dynamisch an veränderte Umweltbedingungen anzupassen.Abstract. This contribution discusses the conceptual design of a flexible workflow management system. After discussing a set of modeling alternatives, a workflow meta schema is developed, using object oriented design principles. We describe how workflows are modelled and executed. Key design decisions are validated using a sample workflow model and a sample workflow instance based on that model. We propose a state transition diagram for workflow instances, and we discuss how dynamic modifications of workflow models can be conducted to adapt running workflow instances to changes in the workflow environment.
