Multi-dimensional state space collapse in non-complete resource pooling scenarios
Ellen Cardinaels, Sem Borst, Johan S. H. van Leeuwaarden
The present paper establishes an explicit multi-dimensional state space collapse (SSC) for parallel-processing systems with arbitrary compatibility constraints between servers and…
Fluid limits for interacting queues in sparse dynamic graphs
Diego Goldsztajn, Sem C. Borst, Johan S. H. van Leeuwaarden
Consider a network of single-server queues where tasks arrive independently at each server at rate . The servers are connected by a graph that is resampled at rate i…
Heavy Loads and Heavy Tails
Sem Borst
The present paper is concerned with the stationary workload of queues with heavy-tailed (regularly varying) characteristics. We adopt a transform perspective to illuminate a close…
Deep Reinforcement Learning for Traffic Light Control in Intelligent Transportation Systems
Ming Zhu, Xiao-Yang Liu, Sem Borst +1
Smart traffic lights in intelligent transportation systems (ITSs) are envisioned to greatly increase traffic efficiency and reduce congestion. Deep reinforcement learning (DRL) is…
Stability of a Stochastic Ring Network
Jaap Storm, Wouter Kager, Michel Mandjes +1
In this paper we establish a necessary and sufficient stability condition for a stochastic ring network. Such networks naturally appear in a variety of applications within communic…
Utility maximizing load balancing policies
Diego Goldsztajn, Sem C. Borst, Johan S. H. van Leeuwaarden
Consider a service system where incoming tasks are instantaneously dispatched to one out of many heterogeneous server pools. Associated with each server pool is a concave utility f…
