Measure-valued fluid limits for partial service queues with correlated patience and service times
Diego Goldsztajn, Fernando Paganini, Andres Ferragut
We consider a many-server queue where tasks with general patience and service times arrive as a renewal process. Contrary to the standard assumptions, we allow for preemption and a…
Geometric lower bounds for the steady-state occupancy of processing networks with limited connectivity
Diego Goldsztajn, Andres Ferragut
We consider processing networks where multiple dispatchers are connected to single-server queues by a bipartite compatibility graph, modeling constraints that are common in data ce…
Optimal local storage policy based on stochastic intensities and its large scale behavior
Matias Carrasco, Andres Ferragut, Fernando Paganini
In this paper, we analyze the optimal management of local memory systems, using the tools of stationary point processes. We provide a rigorous setting of the problem, building upon…
Dynamics and Optimization in Spatially Distributed Electrical Vehicle Charging
Fernando Paganini, Andres Ferragut
We consider a spatially distributed demand for electrical vehicle recharging, that must be covered by a fixed set of charging stations. Arriving EVs receive feedback on transport t…
Quadratic approximate dynamic programming for scheduling water resources: a case study
Agustin Castellano, Camila Martínez, Pablo Monzón +3
We address the problem of scheduling water resources in a power system via approximate dynamic programming.To this goal, we model a finite horizon economic dispatch problemwith con…
Minimal-Variance Distributed Deadline Scheduling
Yorie Nakahira, Andres Ferragut, Adam Wierman
Many modern schedulers can dynamically adjust their service capacity to match the incoming workload. At the same time, however, unpredictability and instability in service capacity…
