چکیده

تحولات دنیای کسب‌وکار و الزامات جدید و تجارت عصر کنونی، زمینه ظهور و بروز نگرش­های جدیدی را فراهم می­کند که ضروری است موردتوجه متصدیان عرصه تولید و تجارت قرار گیرد. در همین راستا رویکرد­ها و نگرش­های جدیدی پیرامون موضوع زنجیره تأمین گسترش یافته است که الزامات زیست‌محیطی آن را به سمت سبز‌بودن سوق می­دهد. در این پژوهش سعی شده است تا علاوه بر تأمین‌کنندگانی که به‌طور مستقیم با شرکت در ارتباط‌اند و قطعات موردنیاز را تأمین می­کنند، تأمین‌کنندگانی که مواد اولیه سازندگان قطعات را فراهم می­کنند نیز به‌عنوان لایه دوم تأمین موردبررسی قرار گیرند و تأمین­کنندگان بهینه در هر دو لایه انتخاب شوند. با در‌نظر‌گرفتن مفاهیم لایه اول و دوم تأمین­کنندگان و همچنین فاکتور سبز با استفاده از روش ارائه‌شده معیاری باعنوان «لایه دوم» و اعداد فازی مرتبط با آن محاسبه می­شود تا در رتبه­بندی تأمین­کنندگان لایه اول به روش تاپسیس فازی سلسله‌مراتبی بر اساس سطوح مختلف آلفا به‌کار گرفته شود؛ بنابراین هدف این پژوهش، پایه­گذاری یک رویکرد سیستماتیک برای ارزیابی و انتخاب دو لایه از تأمین­کنندگان با در‌نظر‌گرفتن عوامل زیست‌محیطی است. اعتبار مدل با استفاده از مثال عددی از شرکت تولید­کننده اجاق‌گاز موردبررسی قرار می­گیرد.

چکیده [English]

Developments in the world of business and new requirements leads to new attitudes which is considered essential for those involved in production and trade. New approaches and attitudes are developed about supply chain that leads to a green one.  The study examined two layer suppliers: first layer (providers of the parts and raw material directly to the manufacturer), and the second layer (providers of parts and raw material for the first layer) finally the study searched for the optimal supplier among them in each layer. To rank suppliers the below item were applieid: the concepts of first and second layers suppliers, green factor, using the proposed method entitled as s"second layer". Then their associated fuzzy numbers were calculated through Hierarchical Fuzzy TOPSIS method based on different levels of alpha. The study tries to establish a systematic approach for evaluating and selecting two layers of suppliers an dat he same time taking into account environmental factors. Manufacturer Stove Companies were the study sample.
