| چکیده | ||
| این مقاله به طراحی شبکۀ تأمین منعطف چند دورهای در یک زنجیرۀ تأمین دوسطحی میپردازد که در آن یک مادۀ اولیه اصلی باید از چند تأمینکننده تهیه شده و محصولات مختلف در چندین سایت تولیدی برای مشتریان تولید شود. مسئله با استفاده از رویکرد برنامهریزی تصادفی دو مرحلهای با در نظر گرفتن تقاضاهای تصادفی مشتریان و قیمتهای تصادفی تأمینکنندگان مدلسازی شده است. بر خلاف مطالعات گذشته، ریسکهای اختلالات تأمین، استراتژیهای کاهشی و برنامههای عملیاتی احتمالی مقابله با ریسکها برای افزایش انعطافپذیری شبکۀ تأمین، همزمان با برنامهریزی تولید محصولات در سایتهای تولیدی بهمنظور نزدیکتر شدن مدل به واقعیت، مد نظر قرار گرفتهاند. طراحی شبکۀ تأمین از دید تصمیمگیرنده ریسک خنثی و تصمیمگیرنده ریسکگریز لحاظ شدهاند. بهدلیل تشریح کاربرد دیدگاه ارائه شده، نتایج محاسبات و اجرای مدل در یک نمونۀ واقعی نشان داده شده است. در نهایت بهمنظور تشریح تأثیر تغییرات در پارامترهای هزینه، روی نتایج مدل آنالیزهای حساسیت انجام گرفته است. | ||

| چکیده [English] | ||
| This paper proposes a multi-period resilient supply network model for a two stage supply chain in which one of the main raw materials should be bought from different suppliers and various products should be produced for customers in several manufacturer production sites. We used two-stage stochastic programming provided that the customers have uncertain demands and the suppliers propose uncertain prices from time to time. In contrast with previous researches, we considered disruption risks of supply, mitigation strategies and contingency plans against risks to improve the resilience of our supply network. Also, to increase the authenticity of our model, we consider the production planning in each production site simultaneously. The supply network design was analyzed from a risk-neutral and a risk-averse decision maker point of view. To illustrate the applicability of our proposed approach, computational results of using this model in a real-life case was presented. Finally, to investigate the influence of cost parameter changes on the results of the model, we performed a sensitive analysis. | ||
