چکیده

در سال‌های اخیر مطالعات زیادی در خصوص چگونگی انتخاب تأمین‌کننده پایدار صورت گرفته است و برای این منظور، مدل‌ها و روش‌های مختلفی در محیط‌های فازی و قطعی پیشنهاد شده است. در این پژوهش برای انتخاب تأمین‌کننده پایدار، یک مدل جدید بر اساس روش بهترین‌-‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌ ‌بدترین که با تئوری مجموعه های راف بهبود یافته است، ارائه می شود. یکی از مزایای روش پیشنهادی، مدل کردن عدم قطعیت مربوط به ارزیابی‌های شخصی و صفر کردن خطای قضاوت ذهنی تصمیم‌گیرنده، با استفاده از رویکرد جدول تصمیم‌گیری می باشد. همچنین با استفاده از مفهوم آنتروپی شرطی در مجموعه‌های راف، معناداری (اهمیت) معیارها محاسبه می‌گردد و انتخاب بهترین و بدترین معیار و نیز انجام مقایسات زوجی در روش بهترین‌-‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌ ‌بدترین، بر این اساس صورت می‌گیرد. با بهره‌گیری از این رویکرد، نرخ ناسازگاری روش بهترین‌-‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌‌ ‌بدترین در تمامی مراحل صفر می‌شود. در ادامه از دو روش TOPSIS و SAW برای تعیین وزن تأمین‌کنندگان استفاده شده است و نتایج با هم مقایسه گردیده است. برای اثبات قابلیت مدل، شرکت ایران خودرو به عنوان مطالعه موردی، برای مسأله انتخاب تأمین‌کنندگان پایدار، در نظر گرفته شده است. نتایج نشان می‌دهد که در رتبه‌بندی تأمین‌کنندگان شرکت ایران‌خودرو بر اساس شاخص‌های پایداری، شرکت ایساکو در رتبه اول قرار دارد.

چکیده [English]

In recent years, many studies have been conducted about how to select a sustainable supplier so different methods have been proposed for this rigard in fuzzy and deterministic environments. In this article a new model of BWM improved using Rough Sets Theory for Sustainable Supplier Selection (SSS) in the supply chain. One of the advantages of the proposed method is modeling the uncertainty related to personal evaluations and zeroing the subjective judgment error of the decision maker, using the decision table approach. Also, using the concept of conditional entropy in rough sets, the significance of criteria is calculated and the selection of the best and the worst criterion, as well as making pairwise comparisons in the best-worst method, is done respectively. Using this approach, the inconsistency ratio of the best-worst method becomes zero in all stages. Moreover TOPSIS and SAW methods have been used to determine the weight of suppliers and the results have been compared. To illustrate the model and demonstrate its capability, a real SSS case in Iran Khodro Company (IKCO), was examined by three experts in the automotive industry. The results show that the first supplier (ISACO Parts Supply Company) is the best sustainable supplier.
