What is MRP (Material Requirements Planning)?
Turkish: MRP
MRP uses bills of materials, inventory, orders, and lead times to plan which materials production needs and when.
What is MRP?
MRP (Material Requirements Planning) is a planning approach that calculates which raw materials, semi-finished goods, and components are needed for production, in what quantities, and at what time.
How Does It Work?
MRP relies on three main inputs: the master production schedule, the bill of materials, and current inventory. The system explodes the bill of materials for each production order, subtracts available stock and open orders, and creates purchase or manufacturing suggestions based on procurement and production lead times.
Business Use
MRP is used to reduce production delays, excess inventory, and critical material shortages. Its output depends heavily on data quality. An incorrect bill of materials, outdated stock balance, wrong scrap rate, or unrealistic lead time can quickly break the plan.
ERP systems connect MRP calculations with accounting, inventory, and purchasing data. SCM looks at demand, capacity, and supplier relationships across the broader supply chain.
