Research focus

Our research focus is on the quantitative analysis of questions related to sustainability and provision of eco-systems services by agri-food systems from farm to global scale. To do so, our team develops and applies different Economic Simulation Models and related methodologies, often in large-scale applications. The software backbone of our models is the Algebraic Modeling Language GAMS, driven by Graphical User Interfaces implemented in Java. We introduce our graduate students in courses to the tools we apply in our research and foster their application in students' projects.

Specific applications include, for instance, mixed-integer, dynamic and stochastic programming, large-scale non-linear and bi-level programming, mixed complementarity problems and constrained systems of non-linear equations. Drawing on computing servers available at institute level, we apply parallel computing, inter alia for large-scale sensitivity analysis. Our models are hosted on a software versioning system, adhere to coding standards and implement quality management based on test suites.

Cooperations

Our group links via various grant funded projects to the German and European research area, sponsored inter alia by the German Research Foundation and the Research Framework programs of the EU Commission, often jointly participating with other teams from the institute or faculty. A close co-operation with EUROCARE, a consulting specialising in quantitative policy impact analysis, supports the access of graduate students and post docs to applied research projects, and helps transfering our scientific findings to stakeholders.
