Stochastic Operations Research (SOR)
Main research interest
The Stochastic Operations Research group (Borst, Boxma) and the Stochastic Networks and Applied Probability group (Van Leeuwaarden) focus on complex systems that operate under randomness and uncertainty, and develop mathematical models and techniques for the analysis and optimization of such systems.
The results provide key insight in the design of resource management strategies and data-driven learning schemes to improve the performance of vital societal networks (internet, wireless networks, dimensioning of large-scale service systems, energy, smart road traffic, healthcare).
We are interested in exploiting the increasing availability of high-volume high-quality data to make better strategic, tactical and operational decisions.
MSc student Paul Krijger (Spyker Prize 2013 of Kivi) used TomTom floating car data to predict traffic light green-red cycles, with the ultimate goal to improve routing recommendations to drivers.

- NETWORKS Zwaartekracht program Bringing together stochastics and algorithmics to model, understand, control and optimize large-scale networks; applications to traffic, communication, healthcare, service engineering and energy networks.
- Services and flows in hospitals project with Mandelbaum (using real hospital data from SEELab, Technion).Real-time locating systems track the flow of both patients and providers in hospitals. Mathematical models describing these flows can detect bottlenecks, and assess the impact of routing and scheduling decisions to improve hospital design.
