Method Details

polling_qsys_klimited

public static double[] polling_qsys_klimited(MatrixCell[] arvMAPs,
 MatrixCell[] svcMAPs,
 MatrixCell[] switchMAPs,
 int[] K)

MAP form. Queue i is served K_i-limited: a visit ends after K_i services or when the queue empties (arrivals during the visit are eligible). E[W_i] + b_i = (1-rho) / (1 - rho - lambda_i R / K_i) (E[W_i^E] + b_i) with E[W_i^E] the exact exhaustive wait of the same system and R the mean total switchover per cycle. Exact for symmetric systems at K=1 and as K grows; for asymmetric systems a queue-by-queue scaling.

Parameters:

K - one positive integer per queue, or a single entry for all queues

Returns:

mean waiting time per queue

polling_qsys_klimited

public static double[] polling_qsys_klimited(MatrixCell[] arvMAPs,
 MatrixCell[] svcMAPs,
 MatrixCell[] switchMAPs,
 int K)

MAP form with the same limit K at every queue.

polling_qsys_klimited

public static double[] polling_qsys_klimited(double[] lambda,
 double[] b,
 double[] b2,
 double[] r1,
 double[] delta2,
 int[] K)

Moment form (see Polling_qsys_exhaustive for the parameters).

Parameters:

K - one positive integer per queue, or a single entry for all queues
