چکیده

امروزه افزایش تقاضا مشتقات نفتی علاوه بر نیاز به مدیریت زنجیره تأمین آن، می‌بایست به ملاحظات زیست‌محیطی فرآیندهای مرتبط با تولید، توزیع و بازیافت آن توجه ویژه­ای داشت. در این رابطه، این پژوهش به طراحی و برنامه‌ریزی شبکه زنجیره تأمین حلقه­بسته سبز برای محصول روغن‌موتور در شرایط عدم قطعیت پرداخته است. مدل ارائه‌شده متشکل از دو هدف می­باشد که تابع هدف اول هزینه‌ها و تابع هدف دوم اثرات نامطلوب زیست‌محیطی شامل آلاینده­های ناشی از بازیافت، حمل‌ونقل مواد بین مراکز مختلف و آلاینده­های ناشی از انهدام مواد غیرقابل بازیافت را کمینه‌سازی می‌کند. با توجه به چندهدفه بودن مدل از روش اپسیلون-محدودیت جهت حل مدل استفاده‌شده است. در مدل موردنظر دو پارامتر میزان تقاضا محصول اصلی و میزان مواد بازگشتی از بازارهای تقاضا به‌صورت غیر‌قطعی در نظر گرفته‌شده است که به‌منظور مقابله با آن از روش بهینه‌سازی استوار مولوی استفاده‌شده است. همچنین، در مدل ارائه‌شده، روش‌های نوین در زمینه بازیافت مواد بازگشتی و انهدام مواد غیرقابل بازیافت موردبحث قرارگرفته است. درنهایت، با استفاده از داده­های شرکت نفت بهران، اعتبار مدل ارائه‌شده مورد ارزیابی قرارگرفته است.

چکیده [English]

Recently, an increase in the demand of petroleum derivatives has caused to pay particular
attention to environmental issues of processes pertaining to its production, distribution and
recovery in addition to the need to manage its supply chain. In this regard, this study has designed
and planned a green closed-loop supply chain network for an engine oil product under
uncertainty. The proposed model encompasses two objectives in such a way the first objective
function aims at minimizing the costs of supply chain and the second one considers
environmental effects of the related activities. In accordance with the multi objectives of the
model, the ε-constraint method is deployed to solve the concerned model. Likewise, the demand
of the main product and the amount of recyclables from the demand markets are presumed to be
hemmed in by uncertainty. To cope with the considered uncertainty, the Mulvey optimization
method is exploited. Meanwhile, new methods for recycling and disposal of non-recyclable
materials are discussed in the proposed model. Eventually, the validation of the proposed model
is evaluated using data from Behran Oil Company.
