Initial and final markings when connection Petrinet to eventlog
We have mined a Heuristics model and made a Petri net from this model. Next, we tried doing a "Replay a log on Petri net for conformance checking". When we do this, we get two warnings, namely one mentioning that the initial marking is an empty marking and the second warning is that 'no final marking is found'.
We have some issue interpreting these markings and are thus unable to correctly run the conformance check. Could someone please explain to us what the initial and final markings are?
Our data is as follows: we have meetings in which we have coded utterances. Every meeting is a case and every utterance code is an event. There are quite some utterances in each meeting and thus the resulting heuristic model has no true beginning or an end, but contains the 'conversational flow'.
Thank you in advance for your help.
Stijn and Marijn
