Description
Leader of the group Stochastics: Bert Zwart.
Many natural and man-made systems and processes are driven by random phenomena. Examples can be found in areas such as communication, energy, information, logistics, and transportation systems. In order to model, describe, and improve such systems, our group develops and studies probabilistic, operational and statistical models. Our group’s analysis of these models relies on techniques from fundamental probability theory, queueing theory, stochastic scheduling, spatial stochastics and stochastic geometry. Our work with various companies in these areas, as well as with top researchers and universities across the globe, ensures our position at the forefront of every aspect of this research field.

CWI and Stichting 113 use data analytics for suicide prevention
Foundation 113 aims at a society in which nobody dies lonely or desperate because of suicide. To achieve this goal, Centrum Wiskunde & Informatica (CWI) and Foundation 113 suicide prevention have recently started a research collaboration.
Health Innovation Seed Fund III B.V. invests in Stokhos emergency mathematics
CWI spin-off company Stokhos Emergency Mathematics receives an investment of Health Innovation Seed Fund III. With this financial injection Stokhos aims to further optimize its software called Seconds, to achieve a scale-up and further international expansion.
CWI researchers make power grid more reliable with mathematics
Researchers from Centrum Wiskunde & Informatica (CWI) discovered how large fluctuations in solar and wind energy, combined with the physical network dynamics of electricity, can cause failures in power grids.
Bart Kamphorst finds best possible scheduling policy for servers in information-scarce settings
Nobody fancies a long wait between requesting some kind of online service and actually receiving that service. Therefore, in many situations, ICT-specialists aim to design their servers in such a way that their customers are served in an efficient manner. Research of CWI PhD-student Bart Kamphorst contributes a number of performance analyses of blind algorithms and moreover identifies a blind algorithm that is in some sense optimal.
