Abstract
We study in this paper an M/G/1 quorum queueing system under T-policy. First, we consider the system size stochastic process embedded at departure epoch times and show that it is an ergodic Markov chain. Then, we consider the system size stochastic process at arbitrary instants of time and show that it is an ergodic semi-regenerative process. We derive the steady-state distribution for both processes. Various system characteristics of related processes (idle and busy periods) are also obtained and special cases are discussed.
