DialogSimulationConfiguration

This dialog can be used to set parameters for the creation of a new log simulating the selected process. The parameters are:

• Configuration presets: whether a predefined noise preset should be used;
• New log name: the name of the log to generate;
• Number of traces: the number of traces of the new log;
• Noise (see [1] for more information):
  • Change activity name probability: the probability of changing an activity name;
  • Trace missing head probability: the probability that a trace is missing its head [1];
  • Trace missing tail probability: the probability that a trace is missing its tail [1];
  • Trace missing episode probability: the probability that a trace is missing an episode [1];
  • Perturbed event order probability: the probability that two events are in inverted order [1];
  • Doubled event probability: the probability that an event is doubled [1];
  • Alien event probability: the probability that an alien event is added to the trace [1];
  • Integer data object error probability: the probability that an integer data object contains an error;
  • String data object error probability: the probability that a string data object contains an error (i.e., a completely different string);
• Noise configuration:
  • Head max size: the maximum size of a trace head (randomly picked, with minimum value, by default, set to 1);
  • Tail max size: the maximum size of a trace tail (randomly picked, with minimum value, by default, set to 1);
  • Episode max size: the maximum size of an episode (randomly picked, with minimum value, by default, set to 1);
  • Integer data object error delta: the delta used to change an integer data object in case of noise (the new value will be randomly picked between old-value - delta and old-value + delta).
