Anyagigénytervezés

Anyagigénytervezés, often translated as Material Requirements Planning (MRP), is a production planning and inventory control system used to manage manufacturing processes. It aims to ensure that materials are available for production and products are available for delivery to customers, while maintaining the lowest possible inventory levels.

The core ofanyagigénytervezés lies in its ability to calculate the exact quantities of raw materials, components, and subassemblies needed to produce a specific product. It takes into account the master production schedule (MPS), which details the quantities and timing of finished goods to be produced. From the MPS, the system determines the gross material requirements.

Next,anyagigénytervezés subtracts the on-hand inventory and scheduled receipts from the gross requirements to determine the net requirements. This calculation is performed for each item in the bill of materials (BOM), which outlines the components and their quantities needed for each product. Lead times for each component are also factored in to ensure materials arrive in time for production.

The output of ananyagigénytervezés system includes planned orders for raw materials and components, as well as planned production orders for subassemblies. It helps businesses to optimize their purchasing and production schedules, reduce lead times, minimize stockouts, and control inventory costs effectively. Modern iterations, often referred to as MRP II (Manufacturing Resource Planning), also incorporate other business functions like finance and human resources.
