يافتن مقدار سفارش و برنامه ي تخفيف در زنجيره ي عرضه ي دوسطحي

The supply chain encompasses every effort involved in producing and delivering a final product or service, from the supplierʹs supplier to the customerʹs customer. Supply chain management includes managing supply and demand, sourcing raw materials and parts, manufacturing and assembly, warehousing and inventory tracking, order entry and order management, distribution across all channels and delivery to the customer. With an overall sight into the whole chain, the supply chain management tries to unify and integrate the entire chain components and come up with an improvement and total cost reduction of the whole chain. In this paper, a one-point discount problem is analyzed, modeled and solved in a two-level supply chain with one supplier and different buyers. The goal is to maximize the supplierʹs profit while minimizing the buyerʹs costs (ordering holding and purchasing), implicitly. The output of the proposed model is the buyerʹs order quantity and the supplierʹs discount offer.
