A robust multi-objective optimization model for inventory and production management with environmental and social consideration: A real case of dairy industry

چکیده
Every day, an abundance of perishable materials and products are transferred from suppliers to producers, as well producers retailers. In the meantime, operating costs, transportation environmental impacts enhance due limited lifespan dairy products, time constraints, inventory hold, high frequency transportation. This paper is about designing a three-level sustainable supply chain under uncertain conditions. this study, multi-objective model proposed minimize total costs impacts, maximize social multi-period multi-product composed suppliers, retailers, which applied company. The delivery first-in, first-out (FIFO) policy particular importance in model. Moreover, robust optimization approach consider uncertainty associated with demand, production holding facilities’ capacity. To solve model, hybrid method based on heuristic algorithm, augmented ?-constraint developed. Based results, economic decreased by 18.5% 25%, respectively. conclusions indicate efficiency applicability also show that developed algorithm can attain high-quality solutions reasonable time.
