Abstract

The highest cost of forecasting for a water distribution network is compared to the design and oversight section of the project. If the goal is to reduce costs, part of this can be achieved by reducing the cost of pipes used in the network and the standard pressure of water in the nodes. This study is a multiobjective optimization function that will be executed in Part of the water distribution network of the Rooydar city in Hormozgan. In optimization of water distribution network, In addition to financial problems, Should be noted to other aspects such as pressure and velocity of water in pipes which have key roles in network design. In the present study, the permitted pressure and standard speed in the network are considered as limitation constraints. For this purpose, in this study, the distribution network using the WaterGems model has been analyzed for hydraulic analysis, and then with coding software matlab2014b including target function and optimization by genetic algorithm according to the network characteristic. At the end of the optimization, Based on the dual objective function, in terms of cost reduction and improve network Pressure, a Scenario with good condition was chosen. This scenario caused a 12-15% reduction in costs.
