How mathematics helps solve complex problems and identify hidden potential for optimisation in order to increase efficiency – but also uncertainty. As part of a statistics lecture, Dr. Benedikt Annweiler from OPTANO gave students practical insights into his everyday work.
Mathematics meets business practice
On Friday, 16 May 2025, Dr. Benedikt Annweiler, Senior Modelling Consultant at OPTANO GmbH, visited inIT. As part of Prof. Dr. Markus Lange-Hegermann's statistics lecture, the mathematician gave a vivid account of his professional experience in mathematical optimisation.
Optimising complex decisions
Under the title 'Embrace Complexity', he demonstrated how companies can use mathematical models to structure and manage complex decision-making processes. The focus is not on reduction, but on the targeted use of complexity — for example, by identifying dependencies, improving processes, and allocating resources strategically.
Everyday working life and real-world applications
Using specific projects at OPTANO as examples, he demonstrated how closely mathematical modelling, software development and customer communication are interlinked in practice. It became clear how strongly direct exchange with customers influences the development of tailor-made solutions – and what a central role interdisciplinary cooperation plays in this. Personal experiences from everyday working life rounded off the presentation.
This gave the students an authentic insight into the everyday working life of a mathematical consultant and introduced them to practical applications of data-based decision support – combined with valuable ideas for their own career orientation.
Networking and practical relevance for students
‘Benedikt and I studied and did our doctorates together in Aachen. It's great that our paths continue to cross. Direct exchange with practitioners provides our students with valuable insights into concrete career prospects,' said Prof. Dr. Markus Lange-Hegermann regarding the guest lecture.
