Rubicon grants for David de Laat and Alessandro Zocca
CWI researchers David de Laat and Alessandro Zocca both received an NWO Rubicon grant. De Laat will study new techniques to compute optimal packings at MIT for one year, and Zocca will study renewables and uncertainty in future power systems at Caltech for two years. NWO granted these subsidies to 22 young, highly promising research talents to gain international research experience at foreign top institutes.
CWI researcher makes higher turnover in hotel bookings possible
With a new mathematical method, hotels can receive on average 5% more turnover in the long term when taking online reviews into account. Dirk Sierag, PhD student of CWI, analysed with historical data the behaviour of consumers booking rooms. Based on the results he designed mathematical models that can support hotels in determining optimal prices of hotel rooms. The research results can also be applied on movies, concerts, sporting events and, for example, Uber taxi rides.
Rob van der Mei in TV programme Universiteit van Nederland

The available budget for this programme is a maximum of € 3.5 million and is provided by the NWO divisions of Social Sciences (MaGW) and Physical Sciences (EW) and the NWO governing board.
CWI launches spin-off Stokhos Emergency Mathematics
Centrum Wiskunde & Informatica (CWI) announces the foundation of its new spin-off Stokhos Emergency Mathematics. Stokhos provides software solutions which enable the proactive relocation of emergency services based on predictions of future demand.
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?
