Application of HBMOA to Pumping Stations Scheduling for a Water Distribution Network with Multiple Tanks

Pumping stations scheduling for water supply systems can be optimized by the Honey Bees Mating Optimization Algorithm (HBMOA). The study-case is the water distribution network of Oradea, Romania, consisting of 4 pumping stations, 3 tanks with variable water level and a constant level water source. The network was simplified, using a numerical network model and data recorded in August 2006, with two daily flow regimes (peak/off-peak). A modified form of HBMOA gave a suboptimal solution (the combination of pumps speed values), which is better, the daily pumping energy consumption being lower, than the one recorded in August 2006.
