  1. Process mining Prof.dr.ir. Wil van der Aalst Eindhoven University of Technology, Department of Information Systems, P.O. Box 513, 5600 MB Eindhoven, The Netherlands w.m.p.v.d.aalst@tm.tue.nl

  2. from languages and systems to analysis ...

  3. Design-time (a-priori) and run-time (a-posteriori) questions Run-time Design-time ProM -verification- validation- performance analysis - process mining

  4. A-posteriori analysis: ProM

  5. Process discovery: Reversing the process process discovery 1

  6. Conformance testing 2

  7. Log based verification formula four_eyes_principle (a1:activity,a2:activity) := forall[p:person | (!(execute(p,a1)) \/ !(execute(p,a2)))]; 3

  8. Outlook ProM CPN Tools ARIS/ARIS PPM YAWL Caramba

  9. XML format

  10. ProM architecture

  11. Demo

  12. More on ProM

  13. Example

  14. Snapshot of log (100 cases)

  15. Alpha plug-in (1)

  16. Alpha plug-in (2)

  17. Multi-phase mining plug-in

  18. Genetic miner (1)

  19. Genetic miner (2)

  20. Social network mining plug-in

  21. SNA with Netminer betweenness metric points out that the editor and the two editorial assistants are most central

  22. Netminer (2)

  23. LTL checker: Input

  24. subformula accept(a : activity ) := {Is the result a some activity an accept?} <> ( (activity == a /\ ate.result == "accept" ) ) ; formula dont_reject_paper_unjustified() := {Are all papers with strong support indeed accepted.} (((accept("get review 1") /\ accept("get review 2")) /\ accept("get review 3")) -> <> ( activity == "accept" ) ); Question 4 accept reject

  25. formula four_eyes_principle(a1:activity,a2:activity) := { <h2>The four-eyes-principle</h2> <p> Check whether two activities are never executed by the same person for a given case.</p> <p> Arguments:<br> <ul> <li><b>a1</b> of type string denoting an activity</li> <li><b>a2</b> of type string denoting an activity</li> </ul> </p> } forall[p:person |(!(execute(p,a1)) \/ !(execute(p,a2)))]; Question 5

  26. A related plug-in: Conformance checker

  27. Conformance checker (1)

  28. Conformance checker (2)

  29. Conformance checker (3)

  30. Additional plug-ins • State space analysis, invariants, EPC reduction/verification, etc.
