The importance of water distribution network reliability lies in the ability of the system to supply the required need with sufficient pressure at normal and abnormal conditions.
In this research, reliability indicators of water distribution networks for Jableh city (Resilience Index (????????), Modified Resilience Index (????????????), Minimum Surplus Head Index (????????)). In order to improve the performance of this network, was used GANetXL (GANetXL is an optimization tool in Excel environment and works based on Genetic Algorithm. We can link with EPANET), to do one-objective and multi-objective optimization of the water distribution network. When the function not only reduced cost but also maximize the reliability indicators. Moreover, the results of a statistical analysis for each pipe in use to determine the sensitive pipes, that are of the most failure probability.
The obtained results showed poor performance of the network resilience index when compared with other indicators under pipe failure conditions, especially in the networks implemented with small diameters. It was also found that if the water distribution network were only optimized in terms of cost, there would be an unacceptable pressure drop at some nodes in case of pipe failure. In addition, it has been found that it is possible to reduce the outage rate by prior maintenance of system components, and reliability can also be improved by turned tree to loop network. We also found that multi-objective optimization yields better results than single-target optimization, and the relationship between reliability and cost is indirect, but reliability increases with decreasing pipe breakage rate.
