The water resource system of Greater Athens supplies water mainly for domestic and industrial use to the metropolitan area of Athens, Greece. The system consists of four reservoirs, groundwater resources, and a network of aqueducts and pumping stations. For the control of this system an integrated computational framework was developed named Hydronomeas, which implements the parameterisation-simulation-optimisation methodology. To allocate the water demand to the different system components, it uses a parametric operation rule thus keeping the number of control variables small. This parametric rule is embedded into a simulation-optimisation scheme. To perform each simulation step, the water resource system is transformed to a digraph, and the water conveyance problem is formulated as a typical transhipment problem, which can be solved by the network simplex algorithm. Global system objectives are incorporated in a performance measure, which is subsequently optimised using nonlinear optimisation methods. Users can specify multiple targets and constraints, give them priorities and set acceptable limits for the system reliability. Hydronomeas is currently used as the main decision support tool for the management of the water resource system of Athens.
