Which process includes controlling the distribution and maintenance of materials in the supply chain?

The process that includes controlling the distribution and maintenance of materials in the supply chain is best described as logistics. This area of supply chain management is focused on the movement, storage, and flow of goods, services, and information from the point of origin to the point of consumption. It encompasses various activities, including transportation management, warehousing, inventory control, and order fulfillment, ensuring that materials are available when and where they are needed while optimizing efficiency and reducing costs.

Logistics plays a critical role in ensuring that products are delivered to customers on time and in the right condition, which is essential for maintaining customer satisfaction and operational efficacy. This process is crucial in linking various components of the supply chain, facilitating the smooth transfer of materials, and adjusting to changes in demand or supply disruptions.
