Welcome to LNMB
the Dutch Network on the Mathematics of Operations Research

LNMB, which stands for "the Dutch Network on the Mathematics of Operations Research (Landelijk Netwerk Mathematische Besliskunde)", is an interuniversity cooperation that brings together researchers in the field of Operations Research. Established in 1987, this collaborative initiative comprises:

1. The Departments of Mathematics of:
   • Delft University of Technology
   • Eindhoven University of Technology
   • Leiden University
   • Maastricht University
   • University of Twente
   • Utrecht University
   • VU Amsterdam
   • Wageningen University & Research


2. The Departments of Economics of:
   • Erasmus University Rotterdam
   • Maastricht University
   • Tilburg University
   • University of Amsterdam
   • University of Groningen
   • VU Amsterdam


3. The Department of Information and Computing Sciences at Utrecht University


4. And the national research institute for mathematics and computer science CWI.

LNMB has dual responsibilities. Firstly, the network provides courses for PhD and Master students. The PhD programme, comprising 18 courses taught in a two-year cycle, aims at broadening and deepening the knowledge of PhD students in the mathematics of Operations Research. Secondly, LNMB serves as an organisation for mathematical researchers specialising in Operations Research. The General Board, representing all universities and CWI, selects an Executive Board to oversee the network's activities. Currently, Prof.dr. G. Schäfer (CWI) is the chairman of the network and Prof.dr. Maria Vlasiou (UT) is its director.

Over the years, the administration of LNMB has transitioned between various universities. Initially administered by the University of Groningen from 1987 to 2001, it was then managed by the University of Maastricht from 2002 to 2006. Subsequently, the University of Twente took over administrative responsibilities from January 2007 until January 2020, followed by the University of Amsterdam from 2020 to 2023. As of 2024, the University of Twente has once again assumed the role of LNMB's administrator.
