In this section, we analyze the stationary probabilities in the QBD process via matrix analytic methods. We will also discuss how the stationary probabilities can be translated into other performance metrics such as the mean response time. We will describe the analysis rather formally, so that a reader can apply the methods immediately. See [111,136,137] for more details and intuitions behind the analysis.
