MRPjärjestelmä

MRPjärjestelmä, an abbreviation for Material Requirements Planning, is a production planning and inventory control system. It is used to manage manufacturing processes, primarily by ensuring that materials are available when needed for production and that products are available for delivery to customers. The system takes into account demand forecasts, production schedules, and current inventory levels to determine what materials need to be purchased or produced, how much, and when.

The core components of an MRPjärjestelmä include a master production schedule (MPS), which outlines the products to be manufactured and their quantities over a specific period. This is then combined with a bill of materials (BOM), which details the components and subassemblies required for each product. Finally, inventory records, which track the quantity on hand, on order, and allocated for each item, are used. By processing these inputs, the MRPjärjestelmä generates planned orders for raw materials and purchased components, as well as planned production orders for subassemblies and finished goods.

The primary benefits of implementing an MRPjärjestelmä include reduced inventory costs, improved production efficiency, better customer service through on-time deliveries, and enhanced planning capabilities. It helps organizations avoid stockouts of critical components and minimizes excess inventory of less critical ones. Modern MRP systems have evolved to include MRP II (Manufacturing Resource Planning), which extends the planning beyond materials to encompass other resources like labor, machinery, and financial data, and Enterprise Resource Planning (ERP) systems, which integrate a wide range of business processes across an entire organization.
