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.

More efficient ambulance planning with new mathematical models
In serious life-threatening situations a fast ambulance response is required. Late arrivals can have a serious impact on the well-being of the patients and can also have consequences regarding policy making. In practice, providing a fast ambulance response time is not always possible. PhD candidate Martin van Buuren of CWI has developed mathematical models that can help to realize fast response times.
Caroline Jagtenberg awarded Rubicon grant
Caroline Jagtenberg, who recently obtained her PhD at CWI, has been awarded an NWO Rubicon grant. With the grant, Jagtenberg will do research at the University of Auckland (New Zealand) for a period of two years.
Stochastics group leader Bert Zwart in 'Economentop 40' of 2017
Stochastics researcher and group leader Bert Zwart is selected to be part of the 'Economentop 40' of 2017, which lists the forty Dutch economists with the highest publication rate in peer reviewed magazines over the past five years.
Caroline Jagtenberg awarded with prestigious Jo van Nunen award
Caroline Jagtenberg, former PhD student of CWI, received the prestigious Jo van Nunen award for her CWI PhD thesis “Efficiency and Fairness in Ambulance Planning” on 30 November. The prize has been awarded by VLM (Vereniging Logistiek Management).
