چکیده

سیستم شبکه توزیع آب شامل انواع منابع عرضه و مراکز تقاضا است. عدم اطمینان در مقدار تقاضا و عرضه در این سیستم‌ها باعث بروز مشکلات فراوانی برای تصمیم‌گیرندگان و طراحان می‌شود. روشهای گوناگونی برای غلبه بر مشکل عدم حتمیت در این نوع از سیستم‌ها مطرح است. در مطالعه حاضر از بهینه‌سازی با پارامترهای کنترل کننده میزان محافظه‌کاری (میزان عدم حتمیت), برای بهینه‌سازی تخصیص آب، در شبکه عرضه آب حوضه آبریز زاینده‌رود استفاده شد. تابع هدف مورد مطالعه، حداقل کردن هزینه‌های مربوط به مراحل طراحی و بهره‌برداری این شبکة عرضه بود. یک دوره‌ی 15 ساله طراحی و بهره‌برداری, شامل دو دوره 5 ساله طراحی برای گسترش و ایجاد تأسیسات جدید و یک دوره 10 ساله بهره‌برداری در شبکه توزیع آب در نظر گرفته شد. نتایج نشان داد که هزینه کل طرح توسعه شبکه توزیع آب در منطقه مورد مطالعه، برابر با 31/1 میلیارد دلار است. بر اساس یافته‌ها، افزایش حوضچه‌های آبهای زیرزمینی برای جبران کمبود آب در منابع آب زیرزمینی توصیه می‌شود. افزون بر آن، افزایش راندمان آبیاری هزینه‌های مربوط به شبکه توزیع آب بخش کشاورزی را کاهش می‌دهد.

چکیده [English]

Water distribution network system includes multiple sources of supply and demand centers. Uncertainty in the amount of demand and supply on these systems causes many problems for decision-makers and designers. Various methods were proposed to overcome the uncertainty problem in these systems. In this study, to allocation of water in the water supply network of Zayandehrud basin, optimization with degree of conservative (degree of uncertainty) controller parameters were used. The objective function of the study was to minimize the water distribution network costs. A 15-year design and operation period (2024-2009) including two 5-year course designed to expand and create new facilities and a 10-year period of operation in the water distribution network was considered. The results showed that the total cost of development of water distribution networks in the study area is 1/31 billion dollars. Based on the findings, increased groundwater fed ponds to compensate for water shortage in the groundwater resources is recommended. In addition, Increase irrigation efficiency reduces costs related to the water distribution network of agricultural sector.
