چکیده

اجرای شبکه‌های جمع‌آوری فاضلاب یکی از راههای موثر در مدیریت کمّی و کیفی منابع آب است. در این مقاله، گزینه مناسب شبکه فاضلاب شهری با استفاده از شاخص‌ها و معیارهای مختلف کمّی و کیفی انتخاب و تأثیر میزان ریسک‌پذیری و ریسک‌گریزی تصمیم‌گیران در انتخاب تصمیم نهایی بررسی شد. انتخاب سیستم مناسب جمع‌آوری فاضلاب شهری به‌عنوان یک مطالعه کاربردی با استفاده از چهار روش تصمیم‌گیری مجموع ساده وزین (SAW)، روش برنامه‌ریزی سازشی (CP)، TOPSIS و عملگر میانگین وزنی مرکب (HWA) مورد بررسی قرار گرفت و تأثیر انتخاب روش تصمیم‌گیری در رتبه‌بندی نهایی گزینه‌ها با استفاده از روشهای ذکر شده بررسی و نتایج حاصل با یکدیگر مقایسه شد.

چکیده [English]

Implementation and operation of municipal wastewater collection systems is an essential part of qualitative water resource management. In this paper, the most appropriate alternative among a set of limited of wastewater collection systems was selected using different quantitative and qualitative attributes. Moreover, the impact of risk attitudes of decision makers (DMs) on selection of the most preferred alternative was evaluated. As a case study the best alternative was examined using four MADM methods including Simple Additive Weighting (SAW), Compromise Programming (CP), TOPSIS, and Hybrid Weighted Averaging (HWA) to validate the application of RB-MADM methods in wastewater collection systems. Then, the impact of selection of MADM method on the final outcome was studied and the results were compared.
