Jaap Wessels


Jacobus Wessels was a Dutch mathematician and Professor of Stochastic Operations Research at the Eindhoven University of Technology., known for his contributions in the field of Markov decision processes.

Biography

Born in Amsterdam, Wessels started to study Mathematics and Physics at the University of Amsterdam in 1956, where in 1963 he received his MA. He graduated in 1968 at the Eindhoven University of Technology advised by Jacques F. Benders with a thesis entitled "Decision rules in Markovian decision problems with Incompletely known transition probabilities" about Markov decision processes.
In 1960 Wessels started his academic career at the University of Amsterdam as assistant to Jan Hemelrijk, an authority in the field of stochastic processes. During his doctoral research, Wessels was employed as Research Assistant at the Technical University of Eindhoven. In 1973 he was appointed Professor of Applied Probability Theory at the Faculty of Mathematics and Computer Science. In 2000 he retired from the Eindhoven University of Technology. He kept participating in International Institute for Applied Systems Analysis and EURANDOM. On July 30, 2009 he died in Veldhoven.
Among his doctoral students were Jacob Wijngaard, Jo van Nunen, Kees van Hee, Jan van der Wal, Henk Zijm, Eric van Damme, Wil van der Aalst, Ivo Adan and Geert-Jan van Houtum.
Wessels was president of the Vereniging voor Statistiek, and has contributed to the foundation of the National Network Mathematical Decision Making, the research school BETA, and European Institute for Statistics, Probability, Stochastic Operations Research and its Applications.

Work

Wessels' research interests focused on topics such as queuing theory, neural networks and structured Markov processes, and more specifically "decision support methodology and he applies his favorite research topics in operations management, communication processes, manpower policy making and environmental problems."

Model-based decision support methodology

Wessels' most cited work is the 2000 publication Model-based decision support methodology with environmental applications, edited with Andrzej Wierzbicki and Marek Makowski. In the introduction they acknowledge about decision making:
This publication gives in three parts an overview of the field.

Publications

Wessel authored and co-authored dozens of publications in the field. Books, a selection:
