First Business, Engineering and Educational Study Group (ESGI 123) in St. Petersburg

The three universities Kyiv Polytechnic, Ukraine, University Koblenz-Landau, Germany and Polytechnic University St. Petersburg, Russia cooperate in organizing a series of Study Groups with Industry.

The three partners are long-term members of ECMI and initiated their collaboration in 2015 with a joint proposal to the German Volkswagen-Foundation. Based on a three years grant, the partners will organize a series of Business, Engineering and Educational Study Groups (BEES-Groups) at their institutes. This series started off with the first BEES-Groups workshop held from Oct 24-28 at the Polytechnic University „Peter the Great“ in St. Petersburg, Russia. This workshop stands in the long tradition of European Study Groups with Industry organized by ECMI and is already the 123rd edition of this format for collaboration between academia and industry. About 25 participants from Croatia, Germany, Finland, Italy, Indonesia, Korea, Russia and Ukraine worked on mathematical models for industrial problems. These problems originated from Airbus Industries, Robert Bosch Russia and Powerflute, Finland. The latter contact was provided by Lappeenranta University of Technology, Finland who organizes together with St. Petersburg since several years binational Finnish-Russian Study Groups with Industry.

The Airbus problem was related to the question on how to find optimal positions for temporal fasteners during the production process of airplane wings. The surface of the wings has to be connected to the underlying frame with a temporal fasteners that can be located a a certain number of discrete positions spread all over the wing. Due to production tolerances each individual wings and frame differ slightly, however the template for the positioning of the fasteners should minimize the overall gap between the two parts for all wings in production. A mathematical optimization problems that asks for ideas how to solve it!

Bosch Russia provided a different problem related to simulations of particles in fluids. The shape of the particles are currently modeled by Bosch using spherical harmonics. Now, one wants to determine the distance of two such particles and to decide whether the might collide or already intersect. How to do that, or does it pay of the switch to another representation of the particles that allows to answer this question easier?

These are just two examples of the industrial problems that were analyzed during this one—week workshop. For details see

The next BEES-Groups will be held at the University in Koblenz, Germany (September 25-29, 2017) and at Kyiv Polytechnic Institute (2018).
