Decomposition of Large Water Distribution Systems

Abstract

Designing a large water‐distribution network as a single entity is difficult. The present practice of designing such a system is by decomposing or splitting it into a number of subsystems. Each subsystem is separately designed and finally interconnected at the ends for reliability. The decision regarding the area to be covered by each subsystem depends on the designer's intuition. Similarly, on computers, designing a large water‐distribution system as a single entity is difficult in terms of computer time and storage. Such a system can also be efficiently designed on computers if divided into small subsystems. Presented herein is an algorithm that divides a large water‐distribution system of predecided multiple‐input points into small subsystems of single input. The algorithm will not only eliminate the present practice of decomposing or splitting by designer's intuition but also enable the designer to design a large water‐distribution system with a reasonable computation effort.
