In queueing models, a discipline within the mathematical theory of probability, the quasi-birth–death process describes a generalisation of the birth–death process. As with the birth-death process it moves up and down between levels one at a time, but the time between these transitions can have a more complicated … See more The stochastic matrix describing the Markov chain has block structure where each of A0, A1 and A2 are matrices and A*0, A*1 and A*2 are irregular matrices for the first … See more The transition rate matrix for a quasi-birth-death process has a tridiagonal block structure See more WebContinuous Time Markov Chain, Level Dependent Quasi Birth Death Process, Hitting Time. 1.

"WebA birth-death process is a continuous-time Markov chain that counts the number of particles in a system over time. Each particle can give birth to another particle or die, and the rate of births and deaths at any given time depends on how many extant particles there are. Birth-death processes are popular modeling tools in evolution, population ... " - Quasi birth-and-death

WebAug 7, 2024 · For dealing numerically with the infinite-state-space Markov chains, a truncation of the state space is inevitable, that is, an approximation by a finite-state-space Markov chain has to be performed. In this paper, we consider level-dependent quasi-birth-death processes, and we focus on the computation of stationary expectations. In previous … WebQuasi-Birth-and-Death (QBD) processes have played a central role in computational probability for the last thirty years [1, 2]. A QBD Markov chain (MC) is a bi-dimensional process where the ﬁrst dimension is called the level and the second the phase [2]. The level behaves as in a traditional birth-and-death process, increasing or decreasing ...
