Supply chain
System involved in supplying a product or service to a consumer
A supply chain is a complex logistics system that consists of facilities that convert raw materials into finished products and distribute them to end consumers or end customers, while supply chain management focuses on the optimization of the flow of goods within the supply chain's distribution channels to ensure efficiency. In sophisticated supply chain systems, the reintroduction of used products into the supply chain may occur at any point where the residual value of the product is recyclable. Supply chains are linked to value chains, and suppliers within a supply chain are often organized into tiers.
