Evaluating shift patterns considering heterogeneous skills and uncertain workforce availability
In shift planning, short-term uncertainties in the availability of workers with different skills often lead to deviations. The strategic calculations based on expected values do not match the actual workforce present. In practice, attempts are then made to fill the different operational positions in the best possible way in each...
Zander Prize for Dr. Steenweg
On September 17, 2020, Dr. Pia Steenweg and Dr. Lisa Grandjean were awarded this year's Ernst Zander Prize for their outstanding dissertations. Pia Steenweg developed optimization methods to adapt duty rosters in shift work as well as possible to the preferences of employees. In addition to working time organization, Pia...
Becker, Bruns, Lier, Werners (2020): Decentralized modular production to increase supply chain efficiency in chemical markets – An example of polymer production
To achieve greater flexibility, innovative production systems have been developed in the chemical industry that provide for decentralized, modular production using standardized apparatus modules in transport containers. The resulting flexibility places high demands on the configuration of the production network and has various implications for economic efficiency, including the fact...
Rachuba, Sebastian; Imhoff, Lisa; Werners, Brigitte (2021): Tactical blueprints for surgical weeks –An integrated approach for operating rooms and intensive care units, European Journal of Operational Research
Decisions about the operations to be performed usually affect the occupancy of downstream resources such as intensive care units (ICU), recovery rooms or regular patient wards. Since the capacity of e.g. ICUs is severely limited, bottlenecks may occur here, leading to cancellations of planned surgeries. Our research results provide action...
Bruns, Bastian; Becker, Tristan; Riese, Julia; Lier, Stefan; Werners, Brigitte (2021): Efficient Production of Specialized Polymers with Highly Flexible Small-Scale Plants, Chemical Engineering & Technology, 44(6), 1148–1152
Modular small-scale chemical plants can be installed in transport containers and offer high flexibility. This paper shows how a mathematical optimization model is used to optimize the economic benefits of small-scale plants for the production of specialty chemicals. Different scenarios created from real data of a chemical company show that...
Information about the chair operation in SS 21
On-site activities of the chair are also limited in SS 21. The planned events will take place in a modified form. You will receive information about the course "Introduction Management Science" at the beginning of the semester in the corresponding Moodle course. The password can be obtained via the password...

How can solutions for complex decision problems be determined? At the chair, current mathematical models and methods are developed and applied in an IT-based manner to provide sound support for difficult decisions in different application areas. In particular, optimization methods and simulation are used for problem structuring, analysis and solution...
