Workflow Exception Patterns [chapter]

Nick Russell, Wil van der Aalst, Arthur ter Hofstede
2006 Lecture Notes in Computer Science  
This paper presents a classification framework for workflow exception handling in the form of patterns.  ...  On the basis of these investigations, we propose a graphical, tool-independent language for defining exception handling strategies in workflows.  ...  The patterns-based approach to exception classification is a continuation of previous research conducted as part of the Workflow Patterns Initiative which has identified "generic, recurring constructs"  ...

Workflow Patterns in Orc [chapter]

William R. Cook, Sourabh Patwardhan, Jayadev Misra
2006 Lecture Notes in Computer Science  
These patterns are useful for evaluating the capabilities of workflow systems and models.  ...  Van der Aalst recently proposed a set of workflow patterns to characterize the kinds of control flow that appear frequently in workflow processes.  ...  Van der Aalst et al. defined a new workflow language, YAWL [10, 12] , specifically to support the workflow patterns.  ...

Workflow User Interfaces Patterns

Josefina Guerrero-García, Juan Manuel González-Calleros, Jean Vanderdonckt
2012 Acta Universitaria  
All WUIPs are stored in a library and can be retrieved within a workflow editor that links each workflow pattern to its corresponding WUIP, thus giving rise to a user interface for each workflow pattern  ...  A collection of user interface design patterns for workflow information systems is presented that contains forty three resource patterns classified in seven categories.  ...  A workflow pattern is another instantiation of a general design pattern.  ...

Workflow patterns put into context

W. M. P. van der Aalst, A. H. M. ter Hofstede
2012 Journal of Software and Systems Modeling  
A Critical Analysis of BPMN, Workflow Patterns and YAWL", Egon Börger criticizes the work of the Workflow Patterns Initiative in a rather provocative manner.  ...  Although the workflow patterns and YAWL are well established and frequently used, Börger seems to misunderstand the goals and contributions of the Workflow Patterns Initiative.  ...  Acknowledgments The authors would like to thank all that contributed to the Workflow Patterns Initiative and the development of YAWL.  ...

Mining unconnected patterns in workflows

Gianluigi Greco, Antonella Guzzo, Giuseppe Manco, Domenico Saccà
2007 Information Systems  
This paper investigates the problem of mining unconnected patterns in workflows and presents for its solution two algorithms, both adapting the Apriori approach to the graphical structure of workflows.  ...  The experiments show that graphical analysis improves the performance of pattern mining by dramatically pruning the search space of candidate patterns.  ...  Given a unconnected pattern p, we say that p is a starting pattern if it contains the starting activity of the workflow schema; otherwise, it is said a terminating pattern.  ...

Parallel computing patterns for Grid workflows

Cesare Pautasso, Gustavo Alonso
2006 2006 Workshop on Workflows in Support of Large-Scale Science  
Whereas a consensus has been reached on defining the set of workflow patterns for business process modeling languages, no such patterns exists for workflows applied to scientific computing on the Grid.  ...  The paper presents how these patterns can be represented in different Grid workflow languages and discusses their implications for the design of the underlying workflow management and execution infrastructure  ...  This pattern has also a close relationship to the classical multi-instance workflow pattern [37] and its variations.  ...
