Research

I am an associate professor at the Econometric Institute of the Erasmus School of Economics, Erasmus University Rotterdam. My research focuses on applications of combinatorial optimization, most notably in railway optimization, or transportation in general. For my Ph.D. thesis, I have developed several extensions of the classical delay management model. After my graduation, I have been working on online delay management and integrated disruption management within the European project ON-TIME. At the moment, I focus on optmization in public transportation in general. Some of the project I am or have been working on are described below.

Together with Thomas Breugem and Dennis Huisman, I am working on railway crew planning. We are currently incorporating fairness aspects in the traditional crew rostering approaches. Together with Rowan Hoogervorst and Dennis Huisman, I am working on rolling stock rescheduling. In particular, we are incorporating delays and adding rescheduling flexibility into existing approaches.

Together with Pedro Munari and Remy Spliet, I work on a generalized formulation for Vehicle Routing Problems (VRPs). The generalized formulation includes the arc-flow and set partitioning formulations as special cases. A preliminary report on this research can be found on ArXiV.

Lukas Bach, a Ph.D. student at Aarhus University, has visited Erasmus University Rotterdam several times since April 2013. Together with Lukas and Dennis Huisman, I work on the integration of train timetabling, engine routing and crew scheduling for a real-world case of DB Schenker, Rail Scandinavia. By allowing for some flexibility in the timetale, the overall costs of the timetable and crew schedule could be reduced by 6-8 percent. A paper on this research has been published in Transportation Science.

I have collaborated with some of my former fellow PhD students. Together with Willem van Jaarsveld, I have looked into an algorithm to solve multi-item inventory problems. We have written a paper on this project that has been published in Omega. Together with Lanah Evers, I have been working on robust solutions to the orienteering problem. Our paper on this research is published in a special issue of Annals of Operations Research. Together with Kristiaan Glorie and Theresia van Essen, I have studied the Tray Optimization Problem (TOP). Here, sterile intruments must be grouped into nets and are then assigned to surgeries. A paper on this research is published in European Journal of Operational Research.

When I was a Ph.D. student, I have worked part-time on crew scheduling at Netherlands Railways (NS). In cooperation with SISCOG, we have developed an algorithm that can tackle the crew scheduling problem for a whole week at once. One of the main results is a crew scheduling algorithm that can solve complete week instances both for drivers and for guards. A paper on this algorithm has been published in Public Transport.
