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.

Mathematical models for optimal coverage of emergency services
Providing proper care in time in emergency situations. This is what emergency services stand for. On 6 June mathematician Pieter van den Berg defends his PhD thesis at TU Delft. He developed models for optimising the logistics of emergency response vehicles.
Increased call center efficiency by identifying redialers
Call centers should base their staff planning on the number of unique callers instead of the total number of calls. Furthermore, introducing a system that gives redialers priority over fresh callers both reduces the average waiting time and improves the fairness of the system. This can be concluded from a study on call center management conducted by CWI.
Firefighters better in position with mathematical model
How could firefighters position themselves even better in a region? If multiple stations are busy fighting a major fire, where should vehicles of other fire stations go to for optimal coverage?
