Alignment-Based Replayer

Dummy version 1.0.0.v202003051301 by PADS RWTH Aachen

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.
