Method Details

polling_qsys_exhaustive

public static double[] polling_qsys_exhaustive(MatrixCell[] arvMAPs,
 MatrixCell[] svcMAPs,
 MatrixCell[] switchMAPs)

Computes mean waiting times for an exhaustive polling system.

polling_qsys_exhaustive

public static double[] polling_qsys_exhaustive(double[] lambda,
 double[] b,
 double[] b2,
 double[] r1,
 double[] delta2)

Moment form. The formulas read only the per-queue arrival rate, the first two service moments and the switchover mean and variance, so a caller holding a law with no MAP (a Det or Uniform switchover, a general service) passes those directly instead of a MAP surrogate of the wrong variance.

Parameters:

lambda - per-queue Poisson arrival rate

b - per-queue mean service time E[S]

b2 - per-queue second service moment E[S^2]

r1 - mean of the switchover out of each queue (Takagi's r_i)

delta2 - variance of the switchover out of each queue

Returns:

mean waiting time per queue
