Çadır Kamplar İçerisinde Su Dağıtım Sisteminin Optimizasyonu

Bu makale, suyun kaynaktan kamplarda kurulan su tanklarına tankerlerle taşınmasına dayanan ve insanların çadırlarına su taşımasına izin veren su taşıma yönteminin yerine, çadır kampları için optimize edilmiş cazibeli bir su şebeke ağı önermektedir; bu yöntem, başka yollarla su temini mümkün olmadığında, çadır kamplarında yaşayan insanlara su temin etmek için kullanılmaktadır. Cazibeli su şebeke ağının kurulum maliyeti, Doğrusal Programlama kullanılarak piyasada bulunan boru çapları seçilerek en aza indirilmiştir. Önerilen yöntem, Alperovits ve Shamir (1977) tarafından geliştirilmiş ve Goulter ve Coal (1986) tarafından modifiye edilmiştir; MATLAB tarafından çözülen lineer denklemler, EPANET'ten elde edilen sonuçlara dayanmaktadır. Suyun tankerlerle sağlandığı Suriye'deki Tulol kampı vaka çalışması olarak seçilmiş ve toplam boru maliyetinin %9,75 azaldığı gözlemlenmiştir.

Optimization of Water Distribution System within Tented Camps

This paper proposes an optimized, gravity-looped water network for tented camps as a replacement of the water trucking method, which depends on conveying water from resource to water tanks set up within camps by trucks, allowing people to carry water through containers to their tent; this method is used to supply people live in tented camps with water when providing water cannot be met in other ways. The cost of installing the gravity-looped network is minimized using Linear Programming to select pipe diameters from commercially available pipes. The method proposed was developed by Alperovits and Shamir (1977) and modified by Goulter and Coal (1986); linear formulations were solved by MATLAB, builds upon results obtained from EPANET. Tulol camp, located in Syria, was chosen as a case study, being supplied with water by trucking. Diameter changes, after optimization, are observed where the total cost of pipes decreased by 9.75%.
