MS23: Data-Driven Optimization

Technical improvements of the recent years allow for many new possibilities in data collection and storage. On the one hand, data is used to optimize industry processes and enhance efficiency. On the other hand, many researchers dedicate to analyze the (big)data sets and employ them for optimization or parameter identification. In this way existing models and processes can be improved and in turn optimization of various industrial applications help to make real life more secure.

With this minisymposium we aim to provide a platform for researchers working with data-driven models and optimization to present state-of-the-art research and connect them to industry. Moreover, we hope to stimulate discussions leading to new research directions and hopefully foster new collaborations among academia and industry.
