Minimizing water cost in the water resource management of Athens

A. Efstratiadis, D. Koutsoyiannis, and D. Xenos, Minimizing water cost in the water resource management of Athens, Urban Water Journal, 1 (1), 3–15, doi:10.1080/15730620410001732099, 2004.



The minimisation of the water cost is examined in the framework of an integrated water resources planning and management model, implemented within the decision support system for the management of the Athens water supply system. The mathematical framework employs a simulation-optimisation scheme, where simulation is applied to faithfully represent the system operation, whereas optimisation is applied to derive the optimal management policy, which simultaneously minimises the risk and cost of decision-making. Real economic criteria in addition with virtual costs are appropriately assigned to preserve the physical constraints and water use priorities, ensuring also the lowest-cost transportation of water from the sources to the consumption. The proposed model is tested in the hydrosystem of Athens, in order to minimise the expected operational cost for several system configurations.
