The group of Process Systems Engineering (PSE) is working on classical topics such as planning and scheduling, supply chain optimization and mathematical optimization of chemical processes and related operational problems with a special attention to energy topics. Special fields of focus are:

1. Process electrification: Converting processes powered by fossil fuels to those driven by electricity, either directly or indirectly, increases reliance on the fluctuating electricity supply and markets. However, it also opens up opportunities for more flexible operations by utilizing energy storage and collaborating with power grids. Investment decisions and the transformation process can be optimized, even when considering future uncertainties such as electricity pricing.
2. Sustainable supply chains: Currently, a significant amount of material is being discarded without properly assessing its potential for reuse or recycling. By evaluating and optimizing different scenarios for integrating processes and value chains at a systems level, we anticipate a substantial increase in the reuse of raw materials and a reduction in environmental burden.
3. Hybrid methods for optimizing large-scale problems: For large and complex mathematical optimization problems, we are reaching the limits of what standard tools can solve effectively. Hybrid methods integrate traditional mathematical solvers with techniques such as heuristics, decomposition methods, and machine learning tools, applied in both the modeling and solution phases

Other topics of interest are waste supply chain management, application of mixed integer linear and non-linear programming methods, and extending the PSE methods to new applications to improve sustainability with simultaneous focus and profitability and operability.
