چکیده

امروزه با برنامه‌­ریزی زنجیره­ تأمین پایدار با در نظر گرفتن اهداف اقتصادی، اجتماعی و زیست­ محیطی باعث ایجاد مزیت رقابتی و افزایش قدرت زنجیره تامین شد. با این وجود تأثیرات پیاده‌­سازی اصول پایداری در تاب‌­آوری یک زنجیره­ تأمین و در مواجهه با اختلالات هنوز به صورت عمیق مورد بررسی پژوهشگران قرار نگرفته است. زنجیره­تأمین تاب‌­آور با بهره‌­مندی از سبد تأمین تاب­‌آور، می‌تواند میزان ریسک و آسیب­‌پذیری زنجیره­‌های­ تأمین را در مواجهه با اختلالات کاهش دهد. در این تحقیق به مدل­سازی مسئله برنامه­‌ریزی پایدار و تاب­­‌آور یک شبکه زنجیره ­تأمین چهارسطحی پرداخته می‌­شود. بدین منظور یک مدل ریاضی چندهدفه توسعه داده می‌­شود که در کنار هدف اقتصادی، برای پایداری زنجیره­تأمین به بیشنه­‌سازی نمرات اجتماعی و زیست­محیطی تأمین ­کنندگان و همچنین کمینه­‌سازی تأخیر در تحویل محصولات پرداخته می‌شود، و از دو روش اپسیلون محدودیت تکامل­ یافته و Lp متریک برای موازنه اهداف استفاده می‌­شود. نهایتا، با استفاده از مثال عددی وتحلیل حساسیت کارایی مدل اثبات می‌­شود.

چکیده [English]

 Today, with the planning of a sustainable supply chain, in addition to achieving economic goals, it can satisfy the social and environmental objectives and considerations, which result in a competitive advantage and increase chain power. However, the effects of implementing the principles of sustainability on the resilience of a supply chain in various disruptions have not yet been deeply studied by the researchers. The resilience supply chain, with the benefit of a resilient supply portfolio, can reduce the risk and vulnerability of supply chains to the extent possible in the face of disturbances such as supply disruptions. In this research, modeling and problem solving of a sustainable resilience planning problem of a four-level supply chain network are discussed. For this purpose, a multi-objective optimization model is developed for this problem. The objectives of the proposed model include minimizing cost, maximization of social and environmental outcomes of the suppliers, as well as minimizing delays in the delivery of products. Two methods of Augmented Epsilon constraint and Lp metric are used for balancing goals. Finally, in the final section of the study, a numerical study is considered. Finally, in the final section of the study, the numerical study is considered. The outputs of the model and the sensitivity analysis indicated that the model was efficient.
