Alignment-based replay is the state-of-the-art technique in conformance checking. Alignments provide a robust and detailed view on the deviations. For each trace from the event log after replaying, there is one alignment corresponding to it.

• 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.
• Move on log
  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.
• Move on model
  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.

With this node, the cost can be set individually for each move on log/model.

Options

Event classifer

The classifier chosen to classify the event log.

Strategy type

The strategy to replay the event log on Petri net. It includes

• ILP Replayer.
  The repalyer calculates the optimal alignment based on ILP.
• Non-ILP Replayer.
• A*-ILP Based Manifest Replayer.
  This replayer is reserved for performance checking. It generates the Manifest to wrap the alignments.

Move on log cost

The unified cost for the move on log in non-negative integer. In default, it is 1.

Move on model cost

The unified cost for the move on model in non-negative integer. In default, it is 1.

Sync move cost

The unified cost for the sync move in non-negative integer. In default, it is 0.

Move on log cost table

The cost table for the move on log with non-negative integer.
The cost table provides the ability to modify cost for each move. The unified move cost can assign the same cost to all items in the table.

Move on model cost table

The cost table for the move on model in non-negative integer.

Sync move cost table

The cost table for the sync move in non-negative integer.

Input Ports

Input port for an event log

Input port for a Petri net

Output Ports

Output replay result after replaying. It includes the alignment, implicitly the corresponding event log and Petri net as well.
