چکیده

مدیریت زنجیرة تأمین سبز، رویکردی زیست­محیطی در مدیریت زنجیرة تأمین است که هدف آن، کاهش ریسک‏های زیست­محیطی در دورة عمر محصول­هاست. در این میان، زنجیرة تأمین بسته، با جمع‏آوری و بازیافت محصول­های مضر در طبیعت، سعی در رسیدن به این هدف دارد. در این مقاله، با توجه به استراتژی‏های مختلف جمع‏آوری محصول، تعدادی مدل قیمتگذاری در زنجیرة تأمین بستة دوسطحی ارائه می‏شود. تعامل­های میان تولیدکننده و خرده‏فروش در قیمتگذاری، براساس بازی استکلبرگ بررسی می­شود و تصمیم‏گیری بهینة تولیدکننده و خرده‏فروش برای هر مدل تعیین می‏شود. همچنین با توجه به ماهیت پویای زنجیرة تأمین در دنیای واقعی، عامل ریسک با استفاده از روش میانگین- واریانس در زنجیرة بسته بررسی می‏شود. برای درک بهتر، مدل‌ها در قالب یک مثال عددی بررسی می­شوند و مدل مناسب با مقایسة مقادیر سود اعضا انتخاب می‏شود. همچنین بر پارامتر‌های نرخ جمع‏آوری، نرخ بازیافت و میزان ریسک‏گریزی، آنالیز حساسیت انجام می‏شود. نتایج نشان می‏دهند که مدل هماهنگی تولیدکننده و خرده‏فروش در نرخ‏‌های جمع‏آوری زیاد و میزان ریسک‌گریزی کم، جایگزین مناسبی برای سایر مدل‏‌هاست.

چکیده [English]

Green supply chain management is an environmental approach in supply chain management that aims to decrease ecological risks in products’ life cycle. Closed-loop supply chain by collecting and recycling the harmful production in nature attempts to achieve this goal. In this paper, due to different strategies in collecting products, several pricing models in two-echelon closed supply chain are presented. The interactions between the manufacturer and the retailer in pricing are investigated based on Stackelberg game and the optimal decisions of manufacturer and retailer are obtained in each model. Moreover, because of the dynamic nature of the supply chain in the real world, risk factor based on the mean-variance model is considered in the closed-loop. Finally, the presented models are analyzed using a numerical example and the best model is selected by comparing the profits. Moreover, sensitivity analyses are performed on collecting rate, recycling rate and the risk aversion. Results show that the coordinating model between the manufacturer and the retailer can be an appropriate substitution in high collecting rates and low risk aversion values.
