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.

EVERYONE who wishes to participate in the meeting, including those who will not stay overnight nor take meals, is requested to register and pay.

Registrations from October 1 are subject to higher fees. If a reservation is cancelled before October 1, then the participation fee will be refunded. Cancellations are not possible after October 1st. In the case of a cancellation contact the responsible organiser.

Registration is closed. Transfer the fee to the appropriate account as indicated on the registration form. Residents of countries outside the SEPA zone or living in a country not using the Euro may pay by credit card or in cash at the meeting, if requested beforehand.

Travel information

De Werelt is easily reached by train. The train station is Lunteren. See the trein schedule or the public transport schedule.

From the train station it is a 15-20 minute walk to De Werelt. See the path on Open Street Maps or Google maps or look at the map below.

Directions for travel by car can be found on the web site of De Werelt.

The forests surrounding De Werelt show all colours in fall and offer nice hiking opportunities during the afternoon. Bring solid shoes with you, though, and watch out for the weather on the rain radar.

On September 14, the kick-off of a new series of events at the Amsterdam health & technology center (AHTC) takes place. Theme of the first event is ‘Smart logistics in healthcare’. CWI's Rob van der Mei will be one of the speakers, as well as Jaap Frank Ponstein, director of Ambulance Amsterdam.

Organizing ambulance services is becoming more and more complex. A city like Amsterdam is making logistics even more challenging. However, thanks to smart technology and data analysis, it is still possible to manage bottlenecks, control costs and stay in charge. How do they do this? And what can other health professionals learn from this?

Uncertainty of various kinds has always played a significant role in energy systems: physically there are uncertain supply and demands, possible failures can propagate in a highly unpredictable fashion, and prices in energy markets can be highly volatile (and can become negative for extended periods of time). Physical safety margins and operational plans are commonly made using robust (worst case) analysis; and strategic decisions are often chosen using the principle of minimising worst regret over scenarios.

The European Union is currently working towards its target of a 20% renewable energy system by 2020, and 97% renewable electricity by 2050. Recent research (Jacobson et al. (2015)) supports the hypothesis that 100% renewable energy systems are achievable by 2050. In order to attain such potential goals, many mathematical problems need to be solved.

The goal of this outreach day is to show a variety of particular problems in this emerging field of research to the Dutch Stochastics community. The workshop is open to other participants as well.

Registration is open to all, and possible until May 18. Participation is free, but please complete the registration form for catering purposes.
