Which of the following is not a concern of the supply chain?

Maintenance scheduling is primarily focused on the upkeep and servicing of equipment, facilities, or machinery involved in production processes or operations, rather than the flow of goods or services throughout the supply chain. Supply chain management mainly deals with the processes that facilitate the movement of products from suppliers to customers, including inventory management, logistics coordination, and supplier selection. Each of these elements is crucial for optimizing the supply chain:

• Inventory management ensures that the right amount of products is available at the right time.
• Logistics coordination involves the planning and execution of the transportation and storage of goods.
• Supplier selection entails finding and vetting suppliers who can provide the necessary materials or products efficiently and effectively.

While maintenance scheduling can indirectly affect supply chain performance by influencing production efficiency, it does not directly concern the fundamental components of supply chain management. Therefore, it stands apart from the other options listed, which are core aspects of managing a supply chain effectively.
