Material requirements planning (MRP) is a computer-based inventory management system designed to assist production managers in scheduling and placing orders for items of dependent demand.
In MRP-based planning, demand plans i.e. sales plans, are created independently from constraints on production and material plans, and production plans are created based on the lead times of the supply chain.
