With the advent of such systems, production efficiency could be greatly improved. As the analysis of data and the technology to capture it became more sophisticated, more comprehensive systems were developed to integrate MRP with other aspects of the manufacturing process.

Enterprise Resource Planning ; Inventory Control Systems 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.

Dependent demand items are components of finished goods—such as raw materials, component parts, and Mrp materials requirements planning which the amount of inventory needed depends on the level of production of the final product.

For example, in a plant that manufactured bicycles, dependent demand inventory items might include aluminum, tires, seats, and bike chains. The first MRP systems of inventory management evolved in the s and s.

They used mainframe computers to explode information from a bill of materials for a certain finished product into a production and purchasing plan for components.

Before long, MRP was expanded to include information feedback loops so that production personnel could change and update the inputs into the system as needed.

The next generation of MRP, known as manufacturing resources planning or MRP II, also incorporated marketing, finance, accounting, engineering, and human resources aspects into the planning process.

A related concept that expands on MRP is enterprise resources planning ERPwhich uses computer technology to link the various functional areas across an entire business enterprise.

MRP works backward from a production plan for finished goods to develop requirements for components and raw materials. MRP begins with a schedule for finished goods that is converted into a schedule of requirements for the subassemblies, the component parts, and the raw materials needed to produce the final product within the established schedule.

MRP is designed to answer three questions: Implemented and used properly, it can help production managers plan for capacity needs and allocate production time. But MRP systems can be time consuming and costly to implement, which may put them out of range for some small businesses.

In addition, the information that comes out of an MRP system is only as good as the information that goes into it. Companies must maintain current and accurate bills of materials, part numbers, and inventory records if they are to realize the potential benefits of MRP.

The bill of materials is a listing of all the raw materials, component parts, subassemblies, and assemblies required to produce one unit of a specific finished product. Each different product made by a given manufacturer will have its own separate bill of materials.

The bill of materials is arranged in a hierarchy, so that managers can see what materials are needed to complete each level of production.

MRP PROCESSING

MRP uses the bill of materials to determine the quantity of each component that is needed to produce a certain number of finished products. From this quantity, the system subtracts the quantity of that item already in inventory to determine order requirements.

The master schedule outlines the anticipated production activities of the plant. Developed using both internal forecasts and external orders, it states the quantity of each product that will be manufactured and the time frame in which they will be needed. The master schedule separates the planning horizon into time "buckets," which are usually calendar weeks.

The schedule must cover a time frame long enough to produce the final product. This total production time is equal to the sum of the lead times of all the related fabrication and assembly operations. It is important to note that master schedules are often generated according to demand and without regard to capacity.1 Material Requirements Planning (MRP) Material Requirements Planning (MRP) is a computer-based production planning and inventory control system.

A materials requirements planning information system is a sales forecast-based system used to schedule raw material deliveries and quantities, given assumptions of machine and labor units required. Material requirements planning (MRP) is a planning and control system for inventory, production, and scheduling.

MRP converts the master schedule of production into a detailed schedule, so that you can purchase raw materials and components.
