Behavioural OR Fall Workshop, Marburg

This is to inform about the upcoming Fall Workshop of the European Working Group on Behavioural Operational Research (BOR) to be held on 06-07 October 2025 in Marburg, Germany.

Please note: A limited number of scholarships for students, each in the amount of €300, will be available. Further information regarding eligibility and the application process will be provided in due course.

The BOR community aims to provide guidance to European OR academics, teachers and practitioners for developing effective OR-supported interventions by investigating and sharing behavioural-based explanations of the factors that shape the practice of modelling, model use and model results communication.

Please find details for submitting your abstract and attending in the details. The program will be updated continuously.

Hoping to meeting you there!

Host and organizer from our COB is Michael Leyer.

Kaiserslautern Applied and Industrial Mathematics Days – KLAIM

The third edition of the

Kaiserslautern Applied an Industrial Mathematics Days – KLAIM

will take place in Kaiserslautern, Germany, from October 6th-8th, 2025.

The purpose of this workshop is to provide a forum for applied mathematicians from academia, research labs and industry to exchange ideas and to showcase recent results. This year’s edition of KLAIM will put emphasis on Coupled Problems. This focus topic reflects the ever increasing complexity in today’s simulation and optimization methods where different problem stages, different scales, or different physical domains and effects are connected in various ways.

The workshop is hosted jointly by the Fraunhofer-Institute for Industrial Mathematics and the Department of Mathematics at the RPTU Kaiserslautern-Landau.

The program is structured along the tracks:

  1. Coupling across scales – multiscale methods in the materials sciences (Organized in collaboration with the French-German Graduate School Mathematical image processing and synthetic microstructures for machine learning)
  2. Coupling across domains – multiphysics simulation
  3. Co-simulation and control in coupled engineering applications (Organized in collaboration with the ECMI Special Interest Group Math for the Digital Factory)
  4. Coupled discrete and bilevel optimization problems
  5. Solver coupling and high performance computing

Additionally, a special session on Success stories from collaboration projects with industry will be organized by the European Network EU-MATHS-IN.

In collaboration with the open access journal Computational Science and Engineering (Editor-in-Chief Peter Benner), we plan a special issue that will comprise a selection of peer-reviewed contributions to KLAIM 2025.

For an overview of the keynote speakers and the Scientific Committee, please see the Call for Papers.

Registration
Registration opens on May 1st, 2025. We invite prospective speakers to submit a one-page abstract to one of the above tracks. Please follow the instructions at the website below for the registration and submission procedure.

ASIM-Fachtagung Simulation in Produktion und Logistik, Dresden

Dresden, 24.09.-26.09.2025, https://www.asim-gi.org/spl2025/home

Als größte europäische Tagung zum Thema Simulation im Bereich Produktion und Logistik gibt die ASIM Fachtagung alle zwei Jahre einen Überblick der zukunftsweisenden Trends, aktuellen Entwicklungen und erfolgreichen Projekte. Präsentiert und diskutiert werden wissenschaftliche Arbeiten sowie interessante Anwendungen aus der Industrie.

Die Veranstaltung bietet die ideale Plattform, um sich mit Referenten und Teilnehmern aus Wissenschaft und Praxis auszutauschen. Im Mittelpunkt der Tagung stehen Einblicke in die Einsatzmöglichkeiten der Simulation, das Kennenlernen neuester Entwicklungen und Produkte sowie das Knüpfen von Fachkontakten. Außerdem bieten Workshops, Tutorials sowie das Rahmenprogramm weitere Gelegenheiten zu vertiefenden Diskussionen und Erfahrungsaustausch.

Fachvorträge sind in deutscher und englischer Sprache möglich. Berichte aus Forschung und Lehre sowie industrieller Entwicklung und Anwendung stehen dabei gleichberechtigt nebeneinander. Die begleitende Firmenausstellung mit Softwareanbietern und Dienstleistern der Simulationsbranche begleitet das Vortragsprogramm und bietet vielfältige Möglichkeiten zur Interaktion.

Die Tagung behandelt traditionelle Themen der Simulation im Kontext der Planung und des Betriebs von Produktions- und Logistiksystemen. Vor dem Hintergrund sich stetig ändernder Rahmenbedingungen, in der u. a. der Bedarf verbesserter Energieeffizienz und erhöhter Resilienz immer dringender wird oder innovative Technologien das Bewährte ersetzen, spielt die Simulation eine entscheidende Rolle zur Gestaltung des Wandels. Diese Schlüsselrolle der Simulation möchten wir auf der Tagung mit Ihnen vertiefen.

Dresden und seine Region haben sich als wichtiger Standort im Rahmen der Halbleiterproduktion und ‑forschung etabliert, weshalb dieses Themengebiet auf der ASIM Fachtagung 2025 einen Schwerpunkt bilden soll. Darüber hinaus möchten wir mit Wissenschaftlern und Praktikern Strategien zur Personal- und Kompetenzentwicklung im Kontext der Simulationsbranche in Zeiten des Fachkräftemangels diskutieren.

Unter dem Thema “Schlüsselrolle Simulation: Wandel gestalten. Herausforderungen meistern.” laden wir Sie herzlich im September 2025 nach Dresden ein. Wir freuen uns auf Ihre Teilnahme und eine gemeinsam gestaltete, inspirierende Tagung.

Workshop „Recent Advances in Multi-Objective Optimization“ (RAMOO), Straubing

The next edition of the workshop „Recent Advances in Multi-Objective Optimization“ (RAMOO) will take place at the Straubing Campus of the Technical University of Munich on 11 and 12 September 2025. The workshop focuses on latest advances in exact methods in multi-objective (mixed) integer optimization. Topics of interest include (but are not limited to):

  • Multi-objective discrete/combinatorial problems

The workshop will start in the morning of Thursday, 11 September, and end around lunchtime on Friday, 12 September. For those traveling from further away, it is thus advisable to arrive already on Wednesday, 10 September. The two keynote talks will be given by Sophie Parragh (Johannes Kepler University Linz) and Oliver Stein (Karlsruhe Institute of Technology). More information can be found on the workshop website (https://moo.univie.ac.at/). The full program and the registration will be available in early July.
