A supply chain is a network of organizations, people, activities, information, and resources involved in the creation and delivery of a product or service to customers. Supply chain management involves the management of these interconnected activities, from sourcing raw materials to the production, distribution, and delivery of goods or services to the end customer. Research in the area of supply chain focuses on improving the efficiency, effectiveness, and sustainability of these processes. This includes studying ways to optimize inventory management, reduce costs, minimize waste, streamline logistics, improve collaboration among supply chain partners, enhance visibility and traceability, and ensure resilience in the face of disruptions. Key areas of research in supply chain management include inventory management, lean manufacturing, logistics, procurement, just-in-time (JIT) systems, and sustainable supply chain practices.
