Collaborative Research Center 823 - Statistical Modelling of Nonlinear Dynamic Processes

The DFG Colaborative Research Center 823 „Statistical Modelling of Nonlinear Dynamic Processes“, founded in 2009 and for which TU Dortmund University is the host university, received a further 8.5 million euros in funding in 2013 and was extended again in 2017. The funds allow the participating university professors from the TU departments of Statistics, Business and Economics, Mechanical Engineering, Physics, Architecture and Civil Engineering, and Mathematics to continue their research. This has led to many successful findings during the first funding period on a broad range of areas, such as the optimization of hearing aids, the analysis of financial market crises, and the optimal processing of concrete.

The Department of Business and Economics is central in covering the important economic apsects of the CRC 823. This is mostly done by the research and teaching areas of Economic Policy (Prof. Dr. Kraft), Applied Economics (Prof. Dr. Linnemann) and Macroeconomics (Prof. Dr. Jung)  in cooperation with the research area of Business and Social Statistics of the Department of Statistics of the TU and the Chair of Economic Policy and Applied Econometrics of the Ruhr-University Bochum.

The Collaborative Research Center 823 focuses on time-varying, dynamic processes in the research fields of economics and engineering. Statistical modeling in these areas is confronted with manifold, interdependent variables and complex processes with sometimes unclear dependencies. These cannot be described with conventional models. One example of this is the financial crisis: Here, almost all economic models failed in diagnosis and forecasting. Whereas in 2007, in calmer stock market times, the stock markets showed different developments and trends, in 2008 the crisis dragged almost all of them into the red - with almost equal losses in percentage terms. But why do international capital markets react similarly in economic downturns? And how can it be explained that the respective markets do not show the same behavior during upswings? The researchers of the CRC 823 are working on finding answers to these questions. In doing so, they try to find and quantify abrupt changes in complex processes, the so-called structural breaks.

The research results to date have been reflected in more than 250 scientific papers published in leading national and international journals.

Location & approach

The campus of TU Dort­mund University is located close to interstate junction Dort­mund West, where the Sauerlandlinie A 45 (Frankfurt-Dort­mund) crosses the Ruhrschnellweg B 1 / A 40. The best interstate exit to take from A 45 is "Dort­mund-Eichlinghofen" (closer to Campus Süd), and from B 1 / A 40 "Dort­mund-Dorstfeld" (closer to Campus Nord). Signs for the uni­ver­si­ty are located at both exits. Also, there is a new exit before you pass over the B 1-bridge leading into Dort­mund.

To get from Campus Nord to Campus Süd by car, there is the connection via Vogelpothsweg/Baroper Straße. We recommend you leave your car on one of the parking lots at Campus Nord and use the H-Bahn (suspended monorail system), which conveniently connects the two campuses.


TU Dort­mund University has its own train station ("Dort­mund Uni­ver­si­tät"). From there, suburban trains (S-Bahn) leave for Dort­mund main station ("Dort­mund Hauptbahnhof") and Düsseldorf main station via the "Düsseldorf Airport Train Station" (take S-Bahn number 1, which leaves every 20 or 30 minutes). The uni­ver­si­ty is easily reached from Bochum, Essen, Mülheim an der Ruhr and Duisburg.

You can also take the bus or subway train from Dort­mund city to the uni­ver­si­ty: From Dort­mund main station, you can take any train bound for the Station "Stadtgarten", usually lines U41, U45, U 47 and U49. At "Stadtgarten" you switch trains and get on line U42 towards "Hombruch". Look out for the Station "An der Palmweide". From the bus stop just across the road, busses bound for TU Dort­mund University leave every ten minutes (445, 447 and 462). Another option is to take the subway routes U41, U45, U47 and U49 from Dort­mund main station to the stop "Dort­mund Kampstraße". From there, take U43 or U44 to the stop "Dort­mund Wittener Straße". Switch to bus line 447 and get off at "Dort­mund Uni­ver­si­tät S".

The H-Bahn is one of the hallmarks of TU Dort­mund University. There are two stations on Campus Nord. One ("Dort­mund Uni­ver­si­tät S") is directly located at the suburban train stop, which connects the uni­ver­si­ty directly with the city of Dort­mund and the rest of the Ruhr Area. Also from this station, there are connections to the "Technologiepark" and (via Campus Süd) Eichlinghofen. The other station is located at the dining hall at Campus Nord and offers a direct connection to Campus Süd every five minutes.


The AirportExpress is a fast and convenient means of transport from Dortmund Airport (DTM) to Dortmund Central Station, taking you there in little more than 20 minutes. From Dortmund Central Station, you can continue to the university campus by interurban railway (S-Bahn). A larger range of international flight connections is offered at Düsseldorf Airport (DUS), which is about 60 kilometres away and can be directly reached by S-Bahn from the university station.


The departments of TU Dortmund University are spread over two campuses, the larger Campus North and the smaller Campus South. Additionally, some areas of the university are located in the adjacent "Technologiepark".
