The working group was founded in the former German Democratic Republic. After the reunification of Germany, it was integrated into the "Deutsche Gesellschaft fuer Operations Research (DGOR)", which became the "Gesellschaft fuer Operations Research (GOR)" after the unification with the "Gesellschaft fuer Mathematik, Oekonomie und Operations Research (GMÖOR)", the other former German OR- Society.
The character of this working group remained essentially the same over all the organizational changes concerning the sponsorship of the group. Its main topics are:
Today the work of the group is based on different groups of researchers capturing a wide range of areas of decision making. The group of Bruno Brosowski is working on non-linear vector optimization problems for various industrial applications. Walter Habenicht and his group are working on discrete vector optimization problems with applications in logistics and scheduling. Applications of vector optimization approaches in physics and engineering are treated by Johannes Jahn, while Heinrich Rommelfanger and his group apply fuzzy approaches to multicriteria decision making. The group of Dieter Schweigert is working on multicriteria combinatorial problems, and Rudolf Vetschera works on multicriteria approaches in group decision making and principal agent theory. Finally, the groups of Gert Wanka and Christiane Tammer do a lot of theoretical work on non-linear vector optimization, especially on duality and control theory.
Every year the group organizes a three-days workshop with
a rather intimate atmosphere. The next workshop will be organized by Walter
Habenicht at Stuttgart-Hohenheim. It will take place on march 21st
? 23rd . Those, who are interested in the workshop, may contact
