Optimum design of the booster chlorination systems by using hybrid HS-Solver optimization approach

Abstract

A hybrid simulation-optimization approach is developed in this study for optimally designing the booster chlorination systems in water distribution networks. In the developed approach, chlorine residuals in the demand locations are determined by using the response matrix (RM) approach. The generated RM is then integrated to an optimization model where a hybrid HS–Solver optimization approach is used.
HS-Solver is a recently proposed hybrid approach which integrates the harmony search (HS) algorithm and a spreadsheet Solver as the global and local optimizers, respectively. The objective of the HS-Solver in the developed approach is for optimally designing the booster stations by maintaining the chlorine residuals within desired limits. The applicability of the developed approach is tested on a real water distribution network. Identified results indicate that the developed
HS-Solver based solution approach determined similar or better results than those obtained by using the different solution approaches in literature.

Hibrit HS-Solver optimizasyon yaklaşımı kullanılarak ek klorlama istasyonlarının optimum tasarımı

Öz

Bu çalışmada, su dağıtım şebekelerindeki ek klorlama istasyonlarının optimum tasarımı amacıyla bir hibrit simülasyon-optimizasyon yaklaşımı geliştirilmiştir. Geliştirilen yaklaşımda, talep noktalarındaki bakiye klor konsantrasyonları tepki matrisi yaklaşımı ile belirlenmiştir. Oluşturulan tepki matrisi ardından hibrit HS-Solver optimizasyon yaklaşımının kullanıldığı bir optimizasyon modeline entegre edilmiştir. HS-Solver, armoni araştırması ile elektronik tablolama programlarında kullanılan Solver eklentisinin sırasıyla global ve lokal optimizasyon aracı olarak kullanıldığı yeni önerilmiş bir optimizasyon yaklaşımıdır. Geliştirilen yaklaşımda HS-Solver’ın amacı bakiye klor konsantrasyonlarını arzu edilen limitlerde tutacak şekilde ek klorlama istasyon sisteminin optimum tasarımını yapmaktır. Geliştirilen yaklaşımın uygulanabilirliği gerçek bir su dağıtım şebekesi üzerinde test edilmiştir. Elde edilen sonuçlar, geliştirilen HS-Solver tabanlı çözüm yaklaşımı ile literatürde verilenlerle uyumlu veya daha iyi sonuçlar elde edilebildiğini göstermiştir.
