Know-how and infrastructure of the research group
Georg Pflug works in the area of stochastic optimization. His interests cover the full scope from statistical data analysis and scenario process generation over approximation and bounding methods to algorithmic issues such as decomposition methods and dynamic optimization formulations of stochastic programs.
A special emphasis of his research program lies on multistage stochastic programs. After having published a book on risk functionals with lots of material on multistage risk functionals (Pflug, Römisch, Modeling, Measuring and Managing Risk, World Scientific 2007) he wrote a new book on multistage stochastic programming with coauthor Alois Pichler (Springer, 2014).
An important result deals with approximation of stochastic programs w.r.t. the nested distance, a generalization of the Wasserstein distance (Pflug and Pichler, 2012). This result has various consequences on scenario generation, bounding techniques and algorithmic issues.
As to the algorithmic side, Georg Pflug has designed new decomposition algorithms for risk-sensitive multistage stochastic programs (published in 2014). He is also an author and editor of a new book on Risk Management in Energy Production and Trading (Springer), an application area of optimization, which is also quite relevant for training the PhD candidates.
The group of Prof. Pflug at the Department of Statistics and Operations Research at the University of Vienna consists of 6 scientific collaborators. Prof. Walter Gutjahr is also associated to this group. The necessary infrastructure (rooms, computing facilities, staff, etc.) is available to conduct these projects.
