Triangular M/G/1-type an tree-like QBD Markov chains

open access: yes, 2011
In applying matrix-analytic methods to M/G/1-type and tree-like QBD Markov chains, it is crucial to determine the solution to a (set of) nonlinear matrix equation(s). This is usually done via iterative methods.

Lower order moments of inter-transition times in the stationary QBD process

open access: yes, 2000
The epochs in which successive increases-or decreases-in the levels of a quasi birth-and-death process QBD process occur are of special interest. In queueing models they usually correspond to the times of successive increments or decrements.

Generation and Analysis of Algorithms for the Study of QBDs

open access: yesTecnoLógicas, 2013
The analysis and characterization of telecommunication systems generally is performed using stochastic models, this paper presents two algorithms for the analysis of quasi birth and death (QBDs), these are implemented on two types of queues PH/PH/1 and M/M/1, showing the results of these and comparing their execution times and error results.
