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.

Cum laude for optimization of hinterland transportation
At large deep-sea ports tens of thousands of containers are handled daily. PhD student Bernard Zweers of CWI's Stochastics group investigated how these containers can be transported to the hinterland as efficient as possible. He received a 'cum laude' degree for this PhD research.
CWI researchers develop new mathematical framework to explain the emergence of large blackouts
The study shows that the statistical distribution of blackout sizes can be linked to city sizes. Bert Zwart and his colleagues indicate that it might be more effective to help consumers react to a blackout instead of performing network upgrades.
In Memoriam Willem van Zwet (1934-2020)
Prof. Willem van Zwet from Leiden University was advisor to the Mathematisch Centrum (now called CWI) from 1965-1984, chair of CWI’s Science Committee and Member of the Board. Throughout his career, Van Zwet played a key role in academic mathematical statistics in the Netherlands.
CWI develops new mathematical techniques for optimal relocation and dispatch of fire trucks
On Monday 11 May Dmitrii Usanov will defend his PhD thesis. His research focused on dispatching and relocating resources in the emergency domain and the reduction of response times.
