Queues with Correlated Service Times -- the $M / M_{D} / c$ Model

Qihui Bu, Suman Thapa, Yiqiang Q. Zhao

This paper studies multi-server queueing systems with correlated service times, modeled as the $M / M_{D} / c$ queue, which is a natural extension of the recent work by Thapa and Zhao \c…

GTH Algorithm, Censored Markov Chains, and $R G$ -Factorization in Block-Form

Qihui Bu, Yiqiang Q. Zhao

In 1985, Grassmann, Taksar, and Heyman published their celebrated paper, in which they introduced a numerically stable algorithm for computing the stationary probabilities of a fin…
