Optimization of start times and product sequences in a multi-line hot rolling mill

In a project together with voestalpine Böhler Edelstahl GmbH & Co KG, the start times and sequence of products in multi-line profile rolling plant are optimized. Based on mathematical models for processing times of all relevant plant sections, an algorithm that computes optimal product start times is developed. The algorithm considers the stochastic nature of the actual processing times. Moreover, a combinatoric optimization problem for the product selection and sequence is formulated and solved.

Observer-based Iterative Learning Control to Improve Path Accuracy of Industrial Robots2018 - 2021

For robotic machining tasks, path accuracy is an essential performance criterion. Due to varying friction, non-constant transmission ratio of the gears and variable stiffness of the robot axes, path deviations occur in industrial robots, which have to be compensated for high-precision processes. In the course of the project, suitable robot models, observer and control strategies are to be designed with which the growing accuracy requirements in industrial manufacturing processes can be achieved.
