  1. Transformation of yEPC Business Process Models to YAWL Jan Mendling Vienna University of Economics Michael Moser Vienna University of Economics Gustaf Neumann Vienna University of Economics

  2. Agenda • What is the Motivation of this transformation? • What EPC extensions do yEPCs introduce? • Differences between yEPCs and YAWL • Conclusion and Future Research ACM SAC - Model Transformation Track

  3. Agenda What is the motivation of this transformation? ACM SAC - Model Transformation Track

  4. Business Process and Workflow Modeling EPCs YAWL ACM SAC - Model Transformation Track

  5. Motivation of yEPCs to YAWL transformation • Lots of business process models are available as EPCs • YAWL is a workflow language with • Execution semantics and • Verification tools • Transformation provides formal semantics of YAWL for yEPCs ACM SAC - Model Transformation Track

  6. yEPC symbols ACM SAC - Model Transformation Track

  7. EPC example from the SAP reference model Function Connector Events ACM SAC - Model Transformation Track

  8. YAWL Notation ACM SAC - Model Transformation Track

  9. YAWL Model for Customer Inquiry ACM SAC - Model Transformation Track

  10. Application of the transformation ACM SAC - Model Transformation Track

  11. Agenda What EPC extensions do yEPCs introduce? ACM SAC - Model Transformation Track

  12. Workflow Patterns Support of EPCs • 20 Workflow Patterns as benchmark • EPCs cannot express: • Deferred choice • Multiple instantiation • State-based patterns • Cancellation patterns ACM SAC - Model Transformation Track

  13. yEPC symbols ACM SAC - Model Transformation Track

  14. Interleaved Parallel Routing ACM SAC - Model Transformation Track

  15. Agenda What are the differences between yEPC and YAWL? ACM SAC - Model Transformation Track

  16. Differences yEPC and YAWL ACM SAC - Model Transformation Track

  17. Multiple Start and End Events ACM SAC - Model Transformation Track

  18. Connector Chains ACM SAC - Model Transformation Track

  19. Events and State Representation ACM SAC - Model Transformation Track

  20. Agenda Conclusion and Future Work ACM SAC - Model Transformation Track

  21. Conclusion Conclusion • yEPC-based modelling of all workflow patterns • yEPC execution semantics via mapping to YAWL • Verification of EPCs using YAWL analysis tools ACM SAC - Model Transformation Track

  22. Application of the transformation 34 of 603 EPC models had formal errors (deadlock, lifelock, etc.) ACM SAC - Model Transformation Track
