Reliability Based Optimal Design of Water Distribution Networks by Genetic Algorithm

摘要

A water distribution network is an important urban hydraulic infrastructure that requires huge capital and maintenance costs. The selection of sizes of pipes, pumps, and other components can be handled effectively by using optimization techniques like the genetic algorithm. The probability of an occurrence of a link failure and capacity to supply the designed demand during the link-failure can be represented as a measure of reliability of the network at the planning stage. In the present work, a new reliability measure is proposed and it is demonstrated by introducing it as a reliability constraint in a genetic algorithm-based optimization method for design of an urban water distribution network.
