System dynamics & optimization

In many of today's economical systems the awareness of sustainability issues is still too low. In order to preserve our planet earth for this and future generations it is essential to use finite and regenerative resources as well as human labor in a sensible way. In the Collaborative Research Center SFB-1026, scientists from the production engineering and environmental technologies will thus work together with economists and mathematicians to address the question of how global production and economical operations can be carried out in a sustainable way. Their goal is to develop new virtual and real production processes that demonstrate the supremacy of sustainable methods over consumption-based ones.

In this project (A6 - Optimization and System Dynamics) we consider the transition of today's dominant, consumption-oriented economical systems into sustainable ones. This leads to mathematical models, which are referred to as continuous, deterministic dynamical systems. They are typically described by ordinary differential equations over time. They describe how a system behaves starting from a given initial condition within a specified time period. As part of the SFB we will develop models with the scientists from the other institutions, which describe the transition from unsustainable to sustainable economical and production system.
These models contain a number of parameters that represent external adjustment, which have counterparts in the real world (e.g., prices, taxes, or incentives). To find out the best-possible settings of the adjustment variables with respect to some sustainability indicators, methods of linear and mixed-integer nonlinear optimization will be applied.
