This node implements the alignment-based replayer, which accepts an event log and a Petri net as input and outputs the optimal alignments of the traces after replaying the event log on the Petri net. Alignment-based replay is the state-of-the-art technique in conformance checking. Alignments provide a robust and detailed view on the deviations between the log and the model. Three types of moves are considered while constructing the alignments:
- Sync Move:
The classification of the current event corresponds to the firing transitions in Petri net. In this case, during replaying, both the trace and the process model move to next comparison. - Log Move:
The classification of the current event doesn't have any corresponding firing transitions in Petri net. During replaying, the trace moves forward but the state of process model doesn't change. - Model Move:
The firing transitions in Petri net have no corresponding event in the trace. During replaying, the model moves forwards but the state of the event log doesn't change.
