Webiis viewed as the death rate when the process is in state i. When a birth occurs, the process goes from state ito state i+ 1. Similarly, when a death occurs, the process goes from state ito state i 1. It is assumed that all births and deaths occur independently. Figure 1: State diagram for a BD process. WebWe establish the finite quasi birth and death (QBD) process of the system. Matrix-geometric approach is utilized to develop the interdependent rate matrix of the QBD, which helps to get the steady state probability vector. The fundamental matrix and covariance matrix of the system are obtained through the infinitesimal generator of the finite ...
