* Batch means method (BM): A simulation method where a simulate run is
  divided in a phase where simulated system reaches an stable state (transient
  phase) and one or more so called batch phases (batches) where batch results
  are obtained. In most cases the batch results are statistical values.
  The batch results are combined into final results.

. The final results may be obtained in a collect run by combining the results of
  several simulate runs where each simulate run generates one or more statistical
  independent batch results.
