Policies for the Operation of an Ambulance Fleet under Uncertainty based on a New Preparedness Metric
Vincent Guigues, Anton Kleywegt, Victor Hugo Nascimento
Two important decisions in the management of an ambulance fleet are ambulance selection decisions and ambulance reassignment decisions. Ambulance selection decisions determine what…
A User Manual for cuHALLaR: A GPU Accelerated Low-Rank Semidefinite Programming Solver
Jacob Aguirre, Diego Cifuentes, Vincent Guigues +3
We present a Julia-based interface to the precompiled HALLaR and cuHALLaR binaries for large-scale semidefinite programs (SDPs). Both solvers are established as fast and numericall…
cuHALLaR: A GPU Accelerated Low-Rank Augmented Lagrangian Method for Large-Scale Semidefinite Programming
Jacob M. Aguirre, Diego Cifuentes, Vincent Guigues +3
This paper introduces cuHALLaR, a GPU-accelerated implementation of the HALLaR method proposed in Monteiro et al. 2024 for solving large-scale semidefinite programming (SDP) proble…
Estimation of Spatiotemporal Poisson Processes with Some Missing Location Data
Vincent Guigues, Anton Kleywegt, Victor Hugo Nascimento +1
We consider models for spatiotemporal Poisson processes with some missing location data. We discuss four models that make provision for missing location data, and their estimation.…
New Heuristics for the Operation of an Ambulance Fleet under Uncertainty
Vincent Guigues, Anton J. Kleywegt, Victor Hugo Nascimento
The operation of an ambulance fleet involves ambulance selection decisions about which ambulance to dispatch to each emergency, and ambulance reassignment decisions about what each…
Management and Visualization Tools for Emergency Medical Services
Vincent Guigues, Anton Kleywegt, Victor Hugo Nascimento +3
This paper describes an online tool for the visualization of medical emergency locations, randomly generated sample paths of medical emergencies, and the animation of ambulance mov…
LASPATED: A Library for the Analysis of Spatio-Temporal Discrete Data (User Manual)
Vincent Guigues, Anton J. Kleywegt, Giovanni Amorim +2
This is the User Manual of the LASPATED library. This library is available on GitHub (at https://github.com/vguigues/LASPATED)) and provides a set of tools to analyze spatiotempora…
LASPATED: a Library for the Analysis of SPAtio-TEmporal Discrete data
Vincent Guigues, Anton Kleywegt, Giovanni Amorim +2
We describe methods, tools, and a software library called LASPATED, available on GitHub (at https://github.com/vguigues/) to fit models using spatio-temporal data and space-time di…
