چکیده

در مقاله پیش رو، یک مدل چندهدفه فازی  و اقتصادی به منظور انتخاب تامین‌‌کننده پایدار و تخصیص سفارش در شرایط فازی و به صورت چند منبعی و دو محصولی در دوسطح زنجیره‌ی تامین، با ملاحظات قیمت‌گذاری ارائه گردیده است. برای ارزیابی تامین‌کنندگان معیارهای اقتصادی شامل هزینه‌ی خرید، حمل و نقل و سفارشات و فاصله و معیارهای اجتماعی و اشتغال نیروی انسانی و اثرات زیست‌محیطی در نظرگرفته  شده و برای اینکه مقادیر مورد نظرپارامترها به واقعیت نزدیک باشند به صورت عدد فازی مثلثی تصادفی و غیرقطعی در نظر گرفته شده است. به منظور حل مدل پیشنهادی از روش دقیق محدودیت اپسیلون در یک مطالعه موردی در صنعت روغن موتور با استفاده از نرم‌افزار گمز انجام گردیده ونتایج تامین‌‌کننده پایدار روغن موتور و گیربکس  در سطح استان زنجان  را مشخص می‌نماید.

چکیده [English]

In this paper, a fuzzy multi-objective sustainable model is presented to select and allocate the order to supplier in uncertainty conditions and in a multi-period, multi-source, and multi-product cases at two levels of supply chain with pricing considerations. First objective function considered in this study as the measures to evaluate the suppliers are the purchase, transportation, and ordering costs. Second objective function considered employment rate and third objective function considered pollution rate. Employment and pollution rate parameters in the model are considered as uncertain and random triangular fuzzy number. A case study in engine oil industry in Zanjan province considered and the epsilon-constraint method is used to solve the small size of this problem and sensitivity analysis is conducted to examine the accuracy and validity of the proposed method.
