...Material Requirements Planning (MRP) 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 subassemblies—for 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 1940s and 1950s. 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 (ERP), which 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...

...needed to properly operate businesses. In order to perform particular tasks, specific specialized software is needed. Material Requirements Planning Among the many operating software systems, one of the most important is the Material Requirements Planning (MRP) system. Material Requirements Planning is the system that manages the process of production planning and inventory. This system uses a technique of inventory, expected receipts, and bill of materials. This system also uses the Master Production Schedule (MPS) to determine the material requirements. There have been four main benefits of having a MRP system in your business. These benefits include, but are not limited to, better responses on customer orders, faster responses on market changes, improve utilization of facilities and labor, and reduced inventory levels (Heizer, J). Capacity Requirement Planning The Capacity Requirement Planning (CRP) is a method that many businesses use to determine the available production capacity. It will start off by assessing the schedule of production that the company has planned. It will then analyze the actual production capacity of the company, and weigh it against the schedule of production to see if the company can meet the schedule with its current production capacity (Capacity Requirements Planning.) Enterprise Resource Planning The Enterprise Resource Planning (ERP) is a software system that effectively plans and controls all resources needed to make, ship, and account for...

...MANUFACTURING RESOURCES PLANNING What is MRP II and why it is being used Definition and History According to American Production and Inventory Control Society, MRP II can be defined as a method of the effective planning of all the resources of a manufacturing company (Higgins, Leroy and Tierney 1996). It is actually advancement or can be said as a upgrading of Material Requirement Planning System (MRP) system, which is a set of technique that uses bills of material, data and a master production schedule to calculate the requirements for materials in a manufacturing company. The MRP system was initiated in the 1960s and was spearheaded by a team of IBM innovators comprising Joe Orlicky, George Plossl and Ollie Wright who sought to create a structured methodology for planning and scheduling materials for complex manufactured products. Over the past 30 years MRP has spawned an entire industry in manufacturing and professional services. It has evolved hand in hand with technological advancements in the computer hardware industry. At the beginning, MRP systems were run on large mainframe computer costing a lot of money and required large technical staff to support them. However in the 1970s they underwent refinements that saw disparate modules get included and critical business concerns such as cost accounting and Capacity Requirements Planning get added. This gave rise to a new generation system called MRP II. Continued changes spurred by increased technological advances coupled...

...Market Structures Allan Williams ECO/GM561 July 26, 2013 Steve Fritch The MRP for the manufacturing of the Riordan electric fans. Materials Requirement Planning (MRP) is a scheduling procedure for production processes that have several levels of production. Given information describing the production requirements of the several finished goods of the system, the structure of the production system, the current inventories for each operation and the lot sizing procedure for each operation, MRP determines a schedule for the operations and raw material purchases. This add-in provides all the features necessary to formulate and solve small examples (www.me.utexas.edu). The material requirement planning of Riordan manufacturing is designed to supply the required material for creating the parts of electric fan in order to produce the components at each phase of assembly line production. The receiving department collects the raw material, which is processed in the molding department to make it suitable for generating parts of the fan after being polished and trimmed in the trimming department. These parts are further processed in the assembly department to make larger components such as fan blades or fan housings. The packaging departments puts each parts of the fan in right package with adequate labeling so that it can be delivered to distribution center through shipping department (University of Phoenix, 2004).

...1.0 MATERIAL REQUIREMENTS PLANNING (MRP) DEFINITION Material requirements planning (MRP) is a production planning and inventory control system used to manage manufacturing processes. It is the process that helps companies makes volume and timing calculation. Most of MRP is based on the software, sometime company use the existing software and make the new software based on the company wants. The objectives of MRP system are to: • Ensure materials are available for production and products are available for delivery to customers. • Maintain the lowest possible material and product levels in store. • Plan manufacturing activities, delivery schedules and purchasing activities. • Required goods are available when required at a right place and time. • Reduce storage and inventory holding cost and improve customer service. MRP system typically requires certain data records which the MRP programs checks and update. The chart below shows the information required to perform MRP and some of the output. Customer order record exactly what each customer has ordered, how many they ordered and when they required delivery. Forecast demand using historical data to predict future trends, cycle and seasonality is always difficult. This process is more to predict of the orders. Inventory record in MRP is to know how some of the required items already in stock. This stock may be in the progress or in raw of material. Bills of the material contains detailed...
