Graduiertenkolleg 1855 "Discrete Optimization of Technical Systems under Uncertainty".

The optimization of technical systems is the central topic of the Research Training Group. Real optimization problems in this context are often characterized by the fact that possible values of the decision variables are chosen from a discrete set, there is a certain uncertainty with respect to various internal and external factors, and the solutions determined by algorithms have to be implemented by human operators and also have to be answered for. This results in requirements for practically usable solutions that go beyond the algorithmic solution of optimization problems with deterministic objective functions and take into account the inherent uncertainty as well as humans as part of the decision process.

The Research Training Group combines methodological sciences with applied sciences and cognitive psychology in order to arrive at practically usable solutions based on sound theory. The subject matter is strongly interdisciplinary and includes three concrete application areas from the engineering sciences. The methodology of discrete optimization under uncertainty - including the implementation of optimization methods in algorithms - is the central aspect of the research training group, which is complemented by the interaction with the human operator of an engineering system. Discrete optimization under uncertainty is a current research topic with immense application potential. The methodological and algorithmic problems involved are very challenging; their solution is of great scientific interest and offers a long-term perspective. Internationally, many groups are working on individual aspects of the topic - but the cross-sectional topic chosen in the Research Training Group represents a unique selling point.

Location & approach

The campus of the Technical University of Dortmund is located near the Dortmund West motorway junction, where the Sauerland line A45 intersects with the Ruhrschnellweg B1/A40. The Dortmund-Eichlinghofen exit on the A45 leads to the south campus, the Dortmund-Dorstfeld exit on the A40 to the north campus. The university is signposted at both exits.

The S-Bahn station "Dortmund Universität" is located directly on the north campus. From there, the S-Bahn line S1 runs every 15 or 30 minutes to Dortmund main station and in the opposite direction to Düsseldorf main station via Bochum, Essen and Duisburg. The university can also be reached by bus lines 445, 447 and 462. Timetable information can be found on the website of the Rhein-Ruhr transport association, and DSW21 also offers an interactive network map.

One of the landmarks of the TU Dortmund is the H-Bahn. Line 1 runs every 10 minutes between Dortmund Eichlinghofen and the Technology Center via Campus South and Dortmund University S, line 2 runs every 5 minutes between Campus North and Campus South. She covers this distance in two minutes.

From Dortmund Airport you can take the AirportExpress to Dortmund Central Station in around 20 minutes and from there you can take the S-Bahn to the university. Düsseldorf Airport, which is about 60 kilometers away, offers a larger range of international flight connections and can be reached directly by S-Bahn from the university train station.
