FEB professor Maarten van der Vlerk and his colleague, researcher Ward Romeijnders, received a NWO Research Talent grant for the project “Approximating mixed-integer recourse models by modifying the recourse data”.
The grant will provide financial support for Ward Romeijnders to do PhD research at FEB. Research Talent is a new programme and offers talented, upcoming researchers the opportunity to fulfil their ambitions of pursuing a scientific career with a three-year PhD research project within social and behavioural sciences.
Mixed-integer recourse models combine the modeling power but also the difficulties of data uncertainty and integer decision variables. These models have a wide range of applications, but are extremely difficult to solve in general. In this project, approximations to mixed-integer recourse models are developed by modifying the recourse data (structure of the model as well as distributions involved). The aim is to find close approximations that can be used to solve real-life problem instances within reasonable computing time.
Maarten van der Vlerk holds the chair Stochastic Optimization, within the research institute OPERA (Operations Management and OperationsResearch), in the Department of Operations. Van der Vlerk's chair specializes in design, analysis and implementation of mathematical models of optimization to support decision-making under uncertainty.
Ward Romeijnders graduated summa cum laude (gpa 9.7) from the master EORAS, for which his master’s thesis about helicopter routing was graded with a perfect 10. His thesis was awarded the FEB-EBF thesis of the year award 2010-2011, and the results were presented at an international scientific conference on scheduling (MISTA 2011, Phoenix). An adapted version of this thesis is submitted to a special issue of the Journal of Scheduling.
His research master’s thesis (under supervision of Van der Vlerk) on approximations for mixed-integer recourse models was graded with a perfect 10 as well, contributing to his second summa cum laude (gpa 9.4) master's title. Ward is also the winner of the FEB-Groningen University Fund-100 Prize, which he received in 2010.
