Andreas Kettner
Optimisation Expert
Essen
Summary
Optimization and modeling expert with 15+ years of experience in data-driven planning, tool development and supply chain optimization.
I specialize in bridging the IT-business interface by managing the entire lifecycle: from business analysis, data acquisition and processing to mathematical modeling, self service reporting and actionable insights. I have a proven track record of creating and maintaining integrated and highly automated LP-based systems that translate complex operative and legislative constraints into day to day value creation and support strategic decision making.
Currently, I am focused on expanding my expertise into power system optimization and electricity market modeling to support the energy transition.
