Johann Hurink

Personal website

Johann L. Hurink is a Full Professor in the Discrete Mathematics and Mathematical Programming group at the University of Twente, where he has worked since 1998. He earned his Ph.D. in 1992 from the University of Osnabrück, Germany, for research on scheduling problems in public transport. He focuses on combinatorial optimization and scheduling, with practical approaches for real-world applications. He has been the director of LNMB in the period 2010-2019. From 2020-2024 he served as Director of the 4TU Applied Mathematics Institute (AMI).

Hurink’s research in the last 10-15 mainly focuses on optimization and control problems in decentralized energy management, thereby covering the complete range from conceptual research to practical applications and real world implementations. One outcome of his multi-disciplinary research group is DEMKit—an open-source toolkit for managing decentralized energy systems. DEMKit offers a framework for modelling, simulation, and real-world deployment of smart grid solutions. His group has collaborated with industry partners and research institutes across Europe, contributing to various national and international projects.

In addition to research, Hurink is actively involved in academic publishing as a Department Editor for OR Spectrum and Associate Editor, OR Letters and Frontiers in Energy Research. With more than 200 refereed publications, his work continues to bridge the gap between conceptual models and practical solutions in operations research and energy systems.

Willem Klein Haneveld

Personal website

Willem Karel Klein Haneveld has been employed at the University of Groningen since 1968, where he retired as Professor in OR in 2006.

His research focuses on mathematical models for decision problems under uncertainty. In 1975, he started a course for graduate students of Econometrics and OR on Stochastic Programming (SP). After his retirement, Maarten van der Vlerk and then Ward Romeijnders lectured this course while improving and extending it, providing it in Groningen as well as in Utrecht for LNMB students. It is thus the longest-standing SP course worldwide.

Klein Haneveld's early theoretical research resulted in his 1986 book "Duality in Stochastic Linear and Dynamic Programming". The key concept is the framework of "LP problems in probabilities" that makes the conjugate duality theory of R.T.Rockafellar very applicable and useful. The book includes amongst others the development of integrated chance constraints — an early precursor to the concept of conditional-value-at-risk, and a robust model for project planning.

In later research, with Leen Stougie, Maarten van der Vlerk and Ward Romeijnders, he contributed to the development of (mixed-) integer SP.

He has also applied SP to various real-world challenges, such as Asset Liability Management for pension funds, agricultural planning in developing countries, and long-term planning of the Dutch gas company Gasunie.

Klein Haneveld was deeply involved with LNMB: as co-founder (1986–1988), as first director (1987–1992) and as chair of the board (1993–1999).
