Optimal scheduling of critically loaded multiclass GI/M/n+M queues in an alternating renewal environment
Ari Arapostathis, Guodong Pang, Yi Zheng
In this paper, we study optimal control problems for multiclass GI/M/n+M queues in an alternating renewal (up-down) random environment in the Halfin-Whitt regime. Assuming that the…
Ergodic control of diffusions with compound Poisson jumps under a general structural hypothesis
Ari Arapostathis, Guodong Pang, Yi Zheng
We study the ergodic control problem for a class of controlled jump diffusions driven by a compound Poisson process. This extends the results of [SIAM J. Control Optim. 57 (2019),…
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…
