G/M/1 Queueing System Analysis.

Implements analysis for G/M/1 queues with general arrival processes and exponential service times. Uses the embedded Markov chain approach to derive exact performance measures for systems with complex arrival patterns but simple service.

Method Details

qsys_gm1

public static Ret.qsys qsys_gm1(double sigma,
 double mu)

Analyzes a G/M/1 queueing system.

Parameters:

sigma - Traffic intensity.

mu - Service rate.

Returns:

qsysReturn containing average waiting time (W) and utilization (rhohat).

qsys_gm1

public static Map<String,Object> qsys_gm1(double sigma,
 double mu,
 Double lambda,
 double[] tPoints,
 double[] percentiles)

Full G/M/1 measures (the MATLAB second output res of qsys_gm1).

Parameters:

lambda - arrival rate, or null (then the time-stationary queue-length measures are omitted)

tPoints - time points of the waiting/sojourn cdfs, or null

percentiles - percentiles of the waiting/sojourn time, or null

Returns:

the res struct, with the MATLAB field names
