PhD student »Mathematical Modelling and Optimization in Drinking Water Supply« (m/f/d)
The Fraunhofer Society is one of the world's leading organisations for application-oriented research. 75 institutes develop groundbreaking technologies for our economy and society – more precisely: 32 000 people from technology, science, administration and IT. You know, who comes to Fraunhofer wants and can change something. For yourself, for us and the markets of today and tomorrow. With the help of multi-criteria optimization methods, we develop innovative solutions for the diverse challenges of our customers from a wide range of industries. The results of our research work create direct benefits in industry and society. Examples of this are the optimized irradiation of tumors and the planning of open-surface photovoltaic systems. Climate change makes the groundwater level in Germany to create. Drought periods and transport lines endangered by heavy rain make it increasingly challenging to ensure the supply of drinking water stable. From a technical point of view, the selection and operation of pumps plays a central role: Flexible requirements for conveying height and quantity should be operated redundantly and energy-efficiently. The aim of the doctorate is to further develop modern mathematical tools from the integral and mixed-gance multi-criteria optimization to support a good selection and operation of the pumps. .

Your tasks • Your profile • What we offer
As part of your doctorate, you will examine the following questions: How can the drinking water supply be mathematically modeled by pump control? How can a (multi-criteria) optimization of drinking water use be carried out? How can fluctuations in demand and supply be taken into account? How can sensitivity be controlled compared to modeling parameters? How can interactive software tools be designed for decision support in politics and water supply?
