On system-wide safety staffing of large-scale parallel server networks

Hassan Hmedi, Ari Arapostathis, Guodong Pang

We introduce a "system-wide safety staffing" (SWSS) parameter for multiclass multi-pool networks of any tree topology, Markovian or non-Markovian, in the Halfin-Whitt regime. This…

Optimal sensor scheduling under intermittent observations subject to network dynamics

Hassan Hmedi, Johnson Carroll, Ari Arapostathis

Motivated by various distributed control applications, we consider a linear system with Gaussian noise observed by multiple sensors which transmit measurements over a dynamic lossy…

Uniform stability of some large-scale parallel server networks

Hassan Hmedi, Ari Arapostathis, Guodong Pang

In this paper we study the uniform stability properties of two classes of parallel server networks with multiple classes of jobs and multiple server pools of a tree topology. These…

Uniform polynomial rates of convergence for a class of Lévy-driven controlled SDEs arising in multiclass many-server queues

Ari Arapostathis, Hassan Hmedi, Guodong Pang +1

We study the ergodic properties of a class of controlled stochastic differential equations (SDEs) driven by -stable processes which arise as the limiting equations of multiclass…

On uniform exponential ergodicity of Markovian multiclass many-server queues in the Halfin-Whitt regime

Ari Arapostathis, Hassan Hmedi, Guodong Pang

We study ergodic properties of Markovian multiclass many-server queues which are uniform over scheduling policies, as well as the size n of the system. The system is heavily loaded…
