Answer:
How many of the materials are needed and when they are needed.
Explanation:
Material requirements planning (MRP) is a system for calculating the materials and components needed to manufacture a product. It consists of three primary steps: taking inventory of the materials and components on hand, identifying which additional ones are needed and then scheduling their production or purchase.
Through adequate materials requirements planning (MRP), the need for manual materials planning is eliminated and the system is able to successfully carry out an efficient strategy.
