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…

Markov Modelling Approach for Queues with Correlated Service Times -- the $M / M_{D} /2$ Model

Suman Thapa, Yiqiang Q. Zhao

Demand for studying queueing systems with multiple servers providing correlated services was created about 60 years ago, motivated by various applications. In recent years, the imp…
