    • polling_qsys_table

      public static double[] polling_qsys_table(MatrixCell[] arvMAPs, MatrixCell[] svcMAPs, MatrixCell[] switchMAPs, int[] table, String discipline)
      MAP form. table holds 0-based queue indices (e.g. {0, 1, 0, 2}); every queue must appear at least once. switchMAPs has one entry PER TABLE POSITION: the switchover of the leg from position m to m+1, the last one closing the cycle. Arrivals must be Poisson (a MAP is reduced to its rate).
      Parameters:
      discipline - "exhaustive" or "gated"
      Returns:
      mean waiting time per queue

      public static double[] polling_qsys_table(double[] lambda, double[] b, double[] b2, double[] s1, double[] sv, int[] table, String discipline)
      Moment form.
      Parameters:
      lambda - per-queue Poisson arrival rate
      b - per-queue mean service time E[S]
      b2 - per-queue second service moment E[S^2]
      s1 - mean switchover of each table position's outgoing leg
      sv - variance of each table position's outgoing leg
      table - 0-based queue index per table position
      discipline - "exhaustive" or "gated"
      Returns:
      mean waiting time per queue
