چکیده

انتخاب تأمین کنندگان نقش مهمی در مدیریت زنجیره تأمین ایفا می‌نماید. توجه به پایداری در زنجیره تأمین سبب شده تا موضوع انتخاب تأمین کنندگان تبدیل به موضوعی چالش برانگیز گردد. در حال حاضر در ادبیات موضوع بیشتر تمرکز بر روی توجه به شاخص‌های اقتصادی به‌منظور انتخاب و ارزیابی تأمین کنندگان بوده و کمتر به عوامل سه‌گانه اقتصادی، زیست محیطی و اجتماعی به عنوان عوامل پایداری توجه شده است. علاوه بر این در ادبیات موضوع روش‌های عمدتاً مبتنی بر برنامه ریزی خطی و چند هدفه، آرمانی، عدد صحیح و غیره جهت ارزیابی تأمین کنندگان استفاده شده است. این در حالی است که عمدتاً معیارهای ارزیابی مبهم، کیفی و شفاهی می‌باشند. در این مقاله تکنیک جدیدی در رابطه با استفاده از تئوری خاکستری جهت ارزیابی تأمین کنندگان ارائه گردیده است که می‌تواند در شرایط ابهام مورد استفاده قرار گیرد و به مدیریت در تصمیم سازی در انتخاب تأمین کنندگان یاری رساند. در این تحقیق بر اساس نظرخواهی از خبرگان شاخص‌های اقتصادی، زیست محیطی و اجتماعی جهت ارزیابی تأمین کنندگان شناسایی گردیده و سپس با استفاده از تئوری خاکستری نسبت به ارزیابی تأمین کنندگان اقدام شده است. نوآوری این تحقیق در ارائه یک تکنیک با سطوح بیشتری از تحلیل در شرایط ابهام با لحاظ کردن عوامل پایداری می‌باشد.  نقطه تمرکز در این مقاله بر روی صنعت فولاد کشور بوده است.

چکیده [English]

Supplier Selection plays an important role in supply chain management. Attention to sustainability in supply chain makes supplier selection more controversial. Current studies have concentrated on economic factors for selection and evaluation of suppliers and there are few emphasis on triple factors including economic, environmental and social elements as the sustainability factors. Also, the methods that are used for supplier evaluation is almost based on linear programming, multi-objective programming, goal programming, integer programming, and the other exact methods. But in real situation, the evaluation criteria are ambiguous, qualitative and verbal. So, in this study, a new technique based on Grey theory is proposed for supplier evaluation that can be used in ambiguous situations. This technique helps managers to decide on supplier selection problems in real scenarios. In this study, the economic, environmental and social indices for suppliers' evaluation are identified based on experts' opinion and by applying Grey theory a technique is developed for suppliers' evaluation.  The novelty of this research is to develop a new technique with more levels of analysis in ambiguity, considering sustainability factors. The case study of this research is steel industry.
