Ignacio E. Grossmann as speaker at the colloquium at the occasion of 20th anniversary of DYN chair

The Chair of Process Dynamics and Operations would like to congratulate Professor Ignacio E. Grossmann on his 65th birthday wishing him many successes in the years to come. On this occasion, Elsevier journal Computers and Chemical Engineering published a special issue entitled "A Tribute to Ignacio E. Grossmann".

Professor Ignacio E. Grossmann, an academic son of Professor Roger Sargent from Imperial College, is a highly influential and leading researcher in process systems engineering. His research over the last forty years have had a unique influence and un-parallel impact in defining, shaping and substantially advancing process systems engineering to a key mainstream scientific engineering field of its own. Among many received awards and honors, Professor Grossmann became a Doctor in Engineering Honoris Causa at the TU Dortmund in 2012.

Visit from the University of Valladolid

UVA Marti Bueno

Two students from the University of Valladolid visited the chair of process dynamics and operations.

Juan Bueno, an Erasmus exchange student, spent nine month from October 2013 to June 2014 within our group. During this time he worked on integration of different control modules of a pipeless plant. The pipeless plant was built by the chair in the scope of the MULTIFORM European project.

Rubén Martí, a PhD student, stayed at the group from April 2014 for three months. During this time he worked on the challenges of two-stage stochastic programming. His main focus was the illustration of different decomposition techniques (price-driven coordination and augmented Lagrangian method) to decompose the problem of two-stage stochastic programming into several deterministic problems.

 

 

Visit of Prof. Henning and Prof. Kawajiri

DSC01947 1

On 4th July 2014, the chairs of Plant and Process Design (Prof. Schembecker) and Process Dynamics and Operations (Prof. Engell) welcomed scientific visitors, Prof. Gabriela P. Henning (INTEC, Santa Fe, Argentina) and Dr. Yoshiaki Kawajiri (School of Chemical & Biomolecular Engineering, Georgia Institute of Technology, USA). The morning program of the visit consisted of two seminars our guests gave related to the topics of their past and present research:

Constraint programming approaches to address predictive and reactive scheduling problems. Prof. Dr. Gabriela P. Henning

Modeling, design, and control for sustainable separation processes. Assistant Professor Dr. Yoshiaki Kawajiri

The afternoon program was devoted to the presentation of the research at the faculty BCI and to the discussions on future scientific collaboration.

Umgang mit Unsicherheit
 

28.02.2014

ab 13 Uhr

Henrichshütte Hattingen

 

Motivation

Unsicherheit im Sinne von unvollständigem Wissen und eingeschränkter Vorhersagbarkeit ist bei all unseren großen und kleinen Entscheidungen des Lebens präsent und muss auch beim Entwurf und beim Betrieb technischer Systeme berücksichtigt werden. Weder die Technik noch ihre Nutzer verhalten sich streng vorhersehbar. Methoden zum systematischen Umgang mit Unsicherheiten in technischen Systemen und die Reduktion von Unsicherheit über das Systemverhalten durch Simulation und Verifikation waren ein roter Faden durch die Forschungsarbeiten meines Lehrstuhls in den letzten 20 Jahren.

In diesem Kolloquium soll ein kleiner Einblick in Methoden zur Bewältigung von Unsicherheit in technischen und ansatzweise in natürlichen Systemen gegeben und der Bogen gespannt werden zum Umgang mit Unsicherheit in sozialen Systemen – von der menschlichen Komponente in Produktionsbetrieben bis zur sprachlichen Kommunikation. Ich hoffe, dass dies zu einer breiteren Sicht und neuen Ideen zum Umgang mit Unsicherheit führt – aber das ist natürlich mit großen Unsicherheiten behaftet, die durch die informellen Rückkopplungen im geselligen Teil reduziert werden wollen.
