چکیده

در سیستم تولید و توزیع آب شرب در مناطق شهری، تعیین برنامه کارکرد الکتروپمپ‌های تأمین آب از مهم‌ترین مسائل عملیاتی است. هزینه الکتریکی مصرفی که تابعی از برنامه کارکرد الکتروپمپ‌ها است، بخش زیادی از هزینه‌های علمیاتی شرکت‌های آب و فاضلاب را به خود اختصاص می‌دهد. در این پژوهش، ضمن مطالعه میدانی در شرکت آب و فاضلاب روستایی سیستان، محدودیت‌های تعیین میزان کارکرد الکتروپمپ‌ها در منابع تأمین آب شامل محدودیت برآورد تقاضا، تأمین آب با کیفیت مناسب و محدودیت بلااستفاده بودن الکتروپمپ‌ها شناسایی شدند. از آنجا که محدودیت‌های مسئله غیرقطعی و فازی هستند، مدل برنامه‌ریزی خطی با محدودیت‌های فازی به‌منظور تعیین ساعات کارکرد الکتروپمپ‌ها در شبانه‌روز با هدف کمینه‌کردن مصرف و هزینه انرژی الکتریکی ارائه شد. پس از جمع‌آوری داده‌های مورد نیاز مدل و اجرای آن، مشخص شد که با استفاده از مدل، هزینه‌های الکتریکی ماهانه تا بیش از 23 درصد کاهش می‌یابد و در نتیجه بهره‌وری افزایش خواهد یافت. برنامه‌ریزی ریاضی فازی پیشنهادی، قابلیت تعیین برنامه کارکرد الکتروپمپ‌ها برای منابع تامین آب با هدف کاهش هزینه‌های انرژی را دارد.

چکیده [English]

One of the most important operational issues in urban drinking water production and distribution systems is to assign a plan for running hours of water supplying electric pumps. The cost of consuming electricity in these pumps allocates most of water and wastewater companies operational costs to itself which is dependent to their running hours. In this paper, meanwhile having a field study in Sistan rural water and wastewater company, the constraints for specifying electric pumps operational time in water supplying resources such as restrictions in fulfilling demand, supply potable water with suitable quality and uselessness of electric pumps have been identified. Due to uncertainty and fuzziness of the constraints, a linear programming model with fuzzy restrictions for determining electric pumps running hours per day is submitted with the aim to minimize electricity consumption and cost. After collecting and using required data for model, it proved that using the proposed model could reduce the costs of electrical energy and increase productivity up to 23 percent per month. The proposed mathematical fuzzy programming is able to specify electric pumps scheduling plan for water supply resources with the aim to reduce the costs of consuming energy.
