Hi @1460047871 ,
I hope you'll get an official reply from Celonis.
In the mean time, I have found that the process discovery is done by constructing a Transition System using directly follows relations (i.e. an arc indicates a directly follows relation). (there are papers, for instance by H.M.W. Verbeek on transition systems that provide more details).
Most important observation here is that not a real process is discovered, but only the directly follows relations are visualized.
As for conformance checking, an algorithm (based on) token based replay is used.
Fun fact: if you go into conformance checking, create a model, and choose for discovery, the inductive miner algorithm (by S.J.J. Leemans) is used to discover a BPMN model.
I hope this helps!
And if anyone has other insights I'm really looking forward to them!!!
Hey, @joos.buijs
Thank you for your reply.
Indeed, I was guessing it was a Transition System. Therefore, I wonder what happens when the process to be discovered has concurrency (AND-splits)? Because theoretically, if there are n concurrent activities, the Transition System will involve up to n! variants, which adds unnecessary complexity.
As for conformance checking, I also noticed that the tool for creating a process model does not allow to insert AND gateways... Maybe concurrency is out of scope in this software.

Hi Rui,
Due to the lack of parallel flows, the model has indeed more (unneccessary) variations. In previous versions of Celonis, you were able to define parallel flows by having a parent and sub process column, see this post from the older community (unfortunately not all images are migrated well): https://www.celopeers.com/s/question/0D50700000GC4mdCAD/parallel-processes-subprocesses
To better show parallel processes, you could use the multi-eventlog, but this is not exactly the same functionality (i.e. you have to define the split, instead that Celonis finds it automatically) and requires a bit more work to set up.
Kind regards,
Jan-peter

Thank you very much @janpeter.van.d !
