Event-Driven Exception Handling for Software Engineering Processes [chapter]

Gregor Grambow, Roy Oberhauser, Manfred Reichert
2012 Lecture Notes in Business Information Processing  
To alleviate this problem, a dynamic exception handling approach for software engineering processes is presented that incorporates event detection and processing facilities and semantic classification  ...  capabilities with a dynamic process-aware information system.  ...  It manages the connection between the project context and the workflows and is responsible for determination of the exceptions as well as the handlings to be applied.  ...

Adaptive exception handling for scientific workflows

Rafael Tolosana-Calasanz, José A. Bañares, Omer F. Rana, Pedro Álvarez, Joaquín Ezpeleta, Andreas Hoheisel
2009 Concurrency and Computation  
We propose an exception handling mechanism, based on techniques adopted in programming languages, for modifying at run-time the structure of a workflow.  ...  Scientific workflow systems often operate in highly unreliable, heterogeneous and dynamic environments, and have accordingly incorporated different fault tolerance techniques.  ...  In case of exception signalling, the descendants only have to signal it and the workflow node must be aware of handling it.  ...

Towards Reference Passing in Web Service and Workflow-Based Applications

Matthias Wieland, Katharina Gorlach, David Schumm, Frank Leymann
2009 2009 IEEE International Enterprise Distributed Object Computing Conference  
Furthermore we show an extension of BPEL that introduces reference variables as new type of data containers in workflows.  ...  In the case the services are orchestrated by workflows the services receive their input values from the workflow engine and return their calculated results back to the engine by value.  ...  Therefore, in [21] a dynamic context variable was described as requirement of context-aware workflows.  ...

Techniques for Supporting Dynamic and Adaptive Workflow

Peter J. Kammer, Gregory Alan Bolcer, Richard N. Taylor, Arthur S. Hitomi, Mark Bergman
2000 Computer Supported Cooperative Work (CSCW)  
Based on this discussion we suggest principal goals to address in the development of adaptive workflow support, including strategies for avoiding exceptions, detecting them when they occur, and handling  ...  The unpredictability of business processes requires that workflow systems support exception handling with the ability to dynamically adapt to the changing environment.  ...  In addition we would like to acknowledge the members of the C2, Chimera, and WebSoft projects at UCI for their exchange of ideas during the development of this system.  ...

Workflow Recovery Framework for Exception Handling: Involving the User [chapter]

Hernâni Mourão, Pedro Antunes
2003 Lecture Notes in Computer Science  
Unexpected exceptions in WfMS are situations not predicted during the design phase. Human involvement in handling this type of exceptions has been recognized to be a crucial factor.  ...  We developed a framework to support the user in handling these situations by redesigning the flow, ad hoc executing the affected tasks, and manipulating engine status.  ...  Some other studies have proposed the adoption of dynamic and adaptive workflow systems to react to exceptions during workflow execution.  ...

E-Commerce und E-Business: Flexible Business Processes - Evaluation of Current Approaches [chapter]

Thomas Burkhart, Peter Loos

Process Invariants: An Approach to Model Expected Exceptions

Pedro Ferreira, Ricardo Martinho, Dulce Domingos
2014 Procedia Technology - Elsevier  
Thus, the process modeler needs to include many expected exceptions in the process model. Consequently, it increases the number of variables and workflow complexity.  ...  Business processes benefit from context information provided by Internet of Things (IoT) technologies. However, business processes tend to have more and more conditions.  ...  Service oriented applications are highly dynamic and easily change at run-time.  ...

2006 Workshop proceedings of the sixth international conference on Web engineering - ICWE '06  
In this paper we propose a framework for the design and development of adaptive Web applications.  ...  ; on the other hand a detached rule engine allows us to widen the set of adaptivity requirements that can be handled and to overcome some limitations of current modeling approaches.  ...  We are now working on implementing the additional modules the integration is based on, namely the Web Action Enactor and the Web Event Dispatcher.  ...

Sigrid Schefer-Wenzl, Helena Bukvova, Mark Strembeck
2014 Lecture Notes in Business Information Processing  
While a number of well-known access control models exists (such as the role-based access control model, for example), standard access control models are often not suited for handling exceptional situations  ...  This paper presents the results of a literature review for 329 delegation and break-glass approaches.  ...  Thus, this approach handles exceptional process executions by dynamically adapting the process flow.  ...
