Multi-Objective Optimization for Water Distribution Management System for Rathnapura District

Abstract

Water is needed for all living things. Water distribution systems are water resources which provide water from the source to customers. Elements like valves, pipes, pumps, tanks, and reservoirs. The primary components for the urbanization are the water distribution system. Today, water distribution systems are very complex. Moreover, large investments are needed to implement and maintain them. To address these issues, it is necessary to create a system to reduce its cost and complexity. The study will concentrate on looking at the use of water distributed by the water board. The main objectives of this research are to derive an optimum water scheduling program, this research study presents a multiobjective optimization problem with the objective functions of 1. Consumed energy and 2. Pressure 3. The water level in tanks 4. Fragmentation. The optimization of both objective functions together leads to a multi-objective constrained optimization problem. To solve the problem, the Non-Dominated Sorting Genetic Algorithm, version II, (NSGA-II) is coupled to the EPANET hydraulic simulation model. In this scheme imitated the network and assess it, tank, pressure, fragment, and power, under the suggested schedule. The result of this method can be described as the most optimal level of pressure, the volume of tanks, cells, and energy levels. The future is to implement another multiobjective algorithm to compare with NSGA II.
