From July 9th to 13th, 2018, the 139 European Study Group with Industry was held in Santiago de Compostela, thanks to the collaboration between the Spanish Network for Mathematics & Industry (math-in) and the Technological Institute for Industrial Mathematics (ITMATI).

139 ESGI concluded with a successful participation and results: the participating researchers managed to find solutions to the five industrial problems. The challenges related to metallurgy, the automotive industry and the improvement of industrial processes were posed by five multinational companies: Repsol, ArcelorMittal, Biomasa Forestal, EcoMT and BorgWarner. In all cases, mathematics was the answer. Technologies such as big data, machine learning and MSO (Modeling, Simulation and Optimization) are behind the solutions, since to reach the automation of the processes first mathematical methodology is needed. Converting a sum of complex calculations in a simplified model without losing accuracy, finding the expression of a physical phenomenon in which numerous variables participate or looking for the relationship between the data collected by sensors are some of the tasks that a mathematician has to address before the machines can get to do their job.

Initiated in Oxford in 1968, the Study Groups with Industry bring together industrial scientists and academic mathematicians to work on problems affecting the industry. These Study Groups represent an internationally recognized method for technology and knowledge transfer between academic institutions and industry.
This edition had 52 participants from 5 different countries (Austria, Spain, Ecuador, Italy and United Kingdom) who managed to find solutions to the five industrial problems: 11 participants from companies, 10 PhD students, 12 grade/master students and 19 researchers and teaching staff.

Organize: Spanish Network for Mathematics & Industry (math-in) and the Technological Institute for Industrial Mathematics (ITMATI). Co-organizes COST Action TD1409, Mathematics for Industry Network (MI-NET).

COST Action TD1409, Mathematics for Industry Network (MI-NET) co-organizes and co-funds this event. The ESGI is also co-funded by the followings:

Ministry of Economy, Industry and Competitiveness through the Thematic Network RTMath-in, granted within the call “Networks of Excellence” 2016

Regional Ministry of Culture, Education and University Planning, Regional Government of Galicia through the Technological Network for Industrial Mathematics (TMATI) and under the agreement that ITMATI has with the Regional Ministry

ROMSOC project financed by the EU within the Horizon 2020 Research and Innovation Programme under the Marie-Skłodowska-Curie grant agreement No 765374.

In this occasion CIEDUS from USC recognized this activity as a training course in the Doctorate Programs: "Mathematical Methods and Numerical Simulation in Engineering and Applied Sciences (USC-UVigo-UDC)" and "Statistics and Operational Research (USC-UVigo - UDC) ", with two modalities: Basic 139 ESGI (1.5 ECTS) and Advanced 139 ESGI (4 ECTS) depending on the involvement of the PhD student in the preparation of the conclusions and the minutes of the event.

The appropriate procedures were also carried out so that this event could be considered as a training course for all the participating researchers of the three Galician universities. Furthermore, this activity is also recognized by the UDC, USC and UVigo as a training activity for the teaching staff.
