Slowdown Services : Staffing Service Systems with Load-Dependent Service Rate

Dong, Jing; Feldman, Pnina; Yom-Tov, Galit - 2018

Many service systems exhibit service slowdowns when the system is congested. Our goal in this paper is to investigate this phenomenon and its e ffect on service performance. We modify the Erlang-A model to account for service slowdowns and perform an asymptotic analysis in the Quality-and-E...

Exploiting Hidden Convexity for Optimal Flow Control in Queueing Networks

Bandi, Chaithanya - 2018

Optimal ﬂow control in queueing networks is a challenging problem occurring in many contexts, such as data centers … queue length and waiting time. We begin by showing that the dynamics of a traditional queueing system can be equivalently …
