Background

About Jochen Deuerlein

Development of mathematical models in hydraulic engineering for planning, design, maintenance and operation of pipe system infrastructure. • Advanced applications of graph theory for network modelling and systems analysis (water, electricity, gas): Decomposition of the network graph, network simplification, analysis of connectivity components, vulnerability, and automatic identification of supply and pressure zones. • Game theoretical modelling of the interaction of control devices with pressure feed-back in water supply networks (variable speed pumps, pressure reducing valves, pres-sure sustaining valves), Proof of existence and uniqueness of the hydraulic steady-state (Nash-equilibrium) of systems with interacting control devices. • Inverse modelling for calibration, design optimization, operation and control of pipe systems (water, gas, district heating). • Real-time simulation and applications for pipe networks • Leak detection in pipe networks. • Water supply network security and risk assessment. • Reliability of pipe networks (water supply, gas, district heating). • Interdependency of critical infrastructure (water, gas, electrical power). • Calculation of parameter sensitivities of hydraulic simulation models. • Mathematical Research interests: Graph theory, nonlinear optimisation and variation-al inequalities, bi-level optimisation. • GIS modelling, data transfer and adaption to hydraulic simulation models.
