چکیده مقاله :
در نگرش جدید جهانی، آب کالایی اقتصادی- اجتماعی بوده و یک عنصر حیاتی در توسعه اقتصادی و اجتماعی هر کشوری محسوب می شود. بنابراین اهمیت کنترل و استفاده بهینه از منابع آبی در دسترس، انکارنشدنی است. برنامه ریزی آرمانی به عنوان ابزاری برای تخصیص بهینه آب، جهت تجزیه و تحلیل و حل مسائلی با آرمان ها و اهداف متعدد استفاده می شود. در مطالعه حاضر به منظور تخصیص بهینه آب سد مهاباد، به عنوان یکی از ده سد پر آب کشور، از برنامه ریزی آرمانی اولویتی استفاده شده است. داده‌های مورد استفاده مربوط به دوره زمانی 1387-1355 بوده که با استفاده از روش مونت کارلو شبیه سازی شده است. اهداف اولویت دار شامل تأمین آب شرب، تأمین آب کشاورزی و تولید برق می باشند. نتایج نشان داد، با توجه به اهداف تصمیم گیرنده و درنظر گرفتن ترتیب اولویت آرمان ها، می توان آب تخصیصی به بخش کشاورزی و شرب را افزایش داد. بدین ترتیب با افزایش تخصیص آب به بخش کشاورزی، می توان سطح زیر کشت بیشتر و به دنبال آن درآمد ناخالص بیشتری بدست آورد. همچنین با اولویت اول قرار دادن تولید برق، می توان برق بیشتری نسبت به دیگر شرایط تولید کرد.
چکیده انگلیسی:
Water is a vital factor in economic and social development of each country. Thus, control and efficient use of available water resources is inevitable. In the present study, in order to determine optimal water allocation of Mahabad Dam reservoir, lexicographic goal programming was used. The data for period 1966-2007 were simulated by the Monte Carlo method. Multiple goals of securing drinking water, agricultural water and electricity production were considered. The results of the study showed that, to maximize objectives of managers, allocation of water to agriculture and drinking could be increased.
