| Abstract | ||
| Simplification of large water supply networks is used for reducing computation times and for making it easier to manage, monitor and analyze. The effect of networks’ simplification on raising the efficiency of pump optimization process is investigated. The key topic of this paper is to produce more optimal pump schedules by using simplified networks. In this research, twelve of demand allocation methods are used after the simplification process and the best one is selected. Then, the simplified network is used for finding a better pump schedule than that produced from the original one under the same conditions, by using Genetic Algorithm (GA) in WaterGEMS V8i software. The produced schedule from the simplified network is applied on the original network to check its performance. Two examples are studied. First, Scheduler Sample1 is reduced by 52 % for pipes and 50 % of nodes. The schedule produced from the simplified network, after applying it on the original network, gives a better solution than that produced from the original one by 9 % in the energy cost along a week and by 12 % in the time for optimization. Second, New El- Minia city network is simplified by removing 82 % from its pipes and 77 % of its nodes. The schedule produced from the simplified network saves the energy consumption along a week by 1.7 % and the time for optimization by 74 % after applying it on the original network. | ||
