Which of the following methods is used to supplement the supply system?

The method of controlled exchange is designed to supplement the supply system by allowing units to exchange equipment or parts across different organizations or units in a controlled manner. This method is particularly useful when a unit has excess supplies or equipment that can be utilized by another unit in need, aiding in efficient resource utilization and reducing delays caused by supply shortages. Controlled exchange helps maintain operational readiness and efficiency within the military by ensuring that assets are allocated where they are most needed.

It is important to understand that while cannibalization, inventory management, and the procurement process all play significant roles in the supply chain, they serve different functions. Cannibalization involves taking parts from non-operational equipment to maintain operational systems, which can sometimes lead to a reduction of available assets. Inventory management focuses on tracking and controlling inventory levels to ensure adequate supplies, while the procurement process involves acquiring new supplies and equipment. Each of these methods addresses different aspects of supply logistics, but controlled exchange specifically acts as a means to supplement existing resources effectively.
