Scheduling jobs with unknown size distribution in a M/G/1 queue: the shifted empirical Gittins
Nicolas Gast, Bruno Gaujal, Adrien Obrecht
In this paper we consider a M/G/1 queue for which we want to minimize the expected response time. We show how to compute indices from samples of the job size distribution such…
Model-Based Learning of Whittle indices
Joël Charles-Rebuffé, Nicolas Gast, Bruno Gaujal
We present BLINQ, a new model-based algorithm that learns the Whittle indices of an indexable, communicating and unichain Markov Decision Process (MDP). Our approach relies on buil…
Integrating Aggregated Electric Vehicle Flexibilities in Unit Commitment Models using Submodular Optimization
Hélène Arvis, Olivier Beaude, Nicolas Gast +2
The Unit Commitment (UC) problem consists in controlling a large fleet of heterogeneous electricity production units in order to minimize the total production cost while satisfying…
Approximations to Study the Impact of the Service Discipline in Systems with Redundancy
Nicolas Gast, Benny van Houdt
As job redundancy has been recognized as an effective means to improve performance of large-scale computer systems, queueing systems with redundancy have been studied by various au…
