Ananyagigénytervezés

Ananyagigénytervezés, often translated as material requirements planning (MRP), is a production planning and inventory control system used by manufacturers. It is designed to ensure that materials are available when they are needed in the production process, while also minimizing the amount of inventory held. The system typically uses a master production schedule, a bill of materials, and an inventory record file to calculate the quantity and timing of materials required.

The master production schedule specifies the end products to be produced and when they are needed. The bill of materials details all the components, subassemblies, and raw materials required to build a finished product. The inventory record file tracks the current stock levels, on-order quantities, and lead times for each item. By analyzing these inputs, MRP systems generate planned orders for purchasing or manufacturing specific items, ensuring that production can proceed without delays caused by material shortages.

The primary benefits of ananyagigénytervezés include reduced inventory costs, improved production scheduling, and increased responsiveness to changes in demand. It helps manufacturers avoid both stockouts and excessive inventory holding costs, leading to greater efficiency and profitability. While originally manual, MRP systems are now typically implemented using specialized software.
