A special celebratory session will feature:

The joint LNMB / NGB Seminar will host: Johan van Rooij (Utrecht University), Peter Hulsen (CQM), Bart Post (CQM), John Poppelaars (Doing the Math), Hein Fleuren (Tilburg University), Koen Peters (WFP Rome), Dennis Huisman (Erasmus University and NS), Erwin Abbink (NS), Tugce Martagan (TU/e), Coen Dirckx (TU/e and Merck), Bram van Ravenstein (Merck), Dick den Hertog (UvA), and Jaap Kwadijk (Deltares).

Programme features

The keynote lectures will highlight recent breakthroughs in fair learning and distributionally robust optimization (Daniel Kuhn), optimal queuing regimes and learning dynamics in games (Marco Scarsini), innovative inventory stocking and revenue management models (Huseyin Topaloglu), and advanced methods for solving challenging combinatorial problems in graph theory (Angelika Wiegele).

With 24 presentations by LNMB PhD students, the programme is rich in a variety of topics. Enjoy sessions on graphs and networks, stochastic programming, pricing, scheduling, control theory, decision models, energy systems, and more! Have a look at the PhD presentations schedule here. Qualifying PhD students will receive their LNMB Diploma on the second day.

The joint LNMB / NGB Seminar on the third day continues our tradition of connecting research in Operations Research with real-world applications. This year’s seminar highlights the success stories of the Dutch Operations Research community with past winners of the prestigious INFORMS Franz Edelman Award.

Do not miss the special session this year celebrating the conference’s golden jubilee! Two of the past LNMB directors, Prof. Dr. Willem Klein Haneveld and Prof. Dr. Johann Hurink, will take us on a memorable journey through the history of LNMB conferences.

The programme gives ample opportunity for informal discussions. Find the programme here and more information about the speakers here.

Sponsors

The conference is generously sponsored by ORTEC and NWO. The LNMB board is grateful to our sponsors for their continued support of Operations Research.

I look forward to welcoming you to our 50th LNMB conference!

Sincerely,

Optimiertes Matching von Angebot und Nachfrage in Free-Floating Car-Sharing Systemen

von Prof. Dr. Felix Weidinger (Gewinner YRA 2024)

Car-Sharing wird häufig als eine wichtige Brückentechnologie in eine nachhaltigere individuelle Mobilität gesehen. Schätzungen zufolge ersetzt in Deutschland ein Pkw in einem Car-Sharing-Angebot abhängig von verschiedenen Einflussfaktoren zwischen drei und zehn privat besessene Pkw (Umweltbundesamt, 2024); Branchenschätzungen sprechen sogar von bis zu zwanzig ersetzen privaten Pkw (Bundesverband Carsharing, 2024).  Dennoch ringen viele Car-Sharing-Anbieter weltweit um den Fortbestand ihrer Car-Sharing-Systeme. Selbst Branchengrößen im Automobilsektor, wie Mercedes-Benz, BMW und General Motors, beendeten vor einigen Jahren ihr Engagement in diesem Bereich, da sie nicht in der Lage waren, die Dienste profitabel zu betreiben (vgl. Wayland, 2020, Hubik, 2022).

Symposium on Decision Diagrams for Optimization

Friday November 22, 2024
Delft University of Technology

Decision diagrams have emerged over the last decade as a versatile and useful tool to represent and solve discrete optimization problems.  The aim of the symposium is to bring together researchers that are interested in methods, algorithms, theory, applications, and tools for optimization that are related to decision diagram technology.  Example topics include discrete optimization, integer programming, handling uncertainty, constraint programming, routing and scheduling, combinatorial optimization, machine learning, and more.

The symposium takes place in the beautiful city of Delft, the Netherlands, on the campus of Delft University of Technology.  It is open to anyone who is interested in attending, ranging from researchers that are established in this area to researchers that wish to learn more about this topic.  The symposium also particularly welcomes PhD students and postdocs, and there is no registration fee.

Please register on the website before November 8, 2024 to confirm your participation.
