  1. Generating Correct EPCs from Configured C-EPCs* Jan Mendling Vienna University of Economics Jan Recker Queensland University of Technology Michael Rosemann Queensland University of Technology Wil van der Aalst Eindhoven University of Technology * The research on the C-EPC is financially supported by SAP Research.

  2. Agenda • What is the idea of configurable reference models? • What are EPCs, what are Configurable EPCs? • How to derive correct EPCs from a configured C-EPC? • Conclusion

  3. Agenda What is the idea of configurable reference models?

  4. From Reference Model of Instantiation

  5. Agenda What are EPCs?

  6. EPC syntax rules: Alternate functions and events No OR and XOR split after events EPC symbols

  7. EPC example from the SAP reference model

  8. Agenda What are Configurable EPCs?

  9. C-EPC Example Configurable EPC Configured C-EPC

  10. Agenda How to derive correct EPCs from a configured C-EPC?

  11. Three steps to arrive at minimal model Goal: Calculate Process Graph that is minimal for configured C-EPC • Derive Configured Connectors • Derive Configured Functions • Apply Graph Reduction to Process Graph Proof-of-Concept Implementation: Input: C-EPC in EPC Markup Language (EPML) extension Output: EPC in EPML

  12. Derive Configured Connectors

  13. Derive Configured Functions

  14. Reduce Graph

  20. Agenda Conclusion

  21. Conclusion • Configuration is promising to leverage reuse of reference models • Configurable reference models make configuration choices explicit • Future research: • Tool support within ProM • Engineering of configurable models

  22. Thank you for your attention!

  23. Agenda What are the problems of deriving configured EPC?

  24. Example of a C-Function in a Sequence

  25. Agenda How to derive configured EPCs?

  26. Why XML-based C-EPCs? • Have C-EPCs machine-processable for • Validation: are requirements met? • Transformation: calculate EPC from C-EPC • Interchange: separate modeling and deployment

  27. Configurable Functions • Configurability: mark function as configurable • Configuration: assign ON, OPT, or OFF to configurable function <function id ='7' name='A'> <configurableFunction> <configuration value='off'/> </configurableFunction> </function>

  28. Configurable Connectors • Configurability: mark connector as configurable • Configuration: assign AND, XOR, OR, or SEQ to c-connector depending on c-connector type <or id ='9'> <configurableConnector> <configuration value='and'/> </configurableConnector> </or>

  29. Further Configurability Aspects • Configuration Requirements:constraints on the allowed configuration – must hold true • Configuration Guidelines:advises on actual configuration – should hold true • Configuration Order:recommended partial order identifying configuration sequences <configurationRequirement idRefs=’list of xs:integer’> <if xpath=’xpath-statement’/> <then xpath=’xpath-statement’/> </configurationRequirement>

  30. C-EPC Validator based on XSLT

  31. Conclusion • Configuration is promising to leverage reuse of reference models • Configurable reference models make configuration choices explicit • Derivation of EPCs from C-EPCs • Future research: • Tool support • Engineering of configurable models
