Material requirements planning assignment help
Material requirements planning (MRP) is a system for calculating the materials and components needed to manufacture a product. It consists of three primary steps: taking inventory of the materials and components on hand, identifying which additional ones are needed and then scheduling their production or purchase. MRP stands for material requirements planning. It is the digital version of a formal project management process. MRP is used by designers to manage the tasks necessary to create a design, including estimating tasks and identifying which ones directly fit with the designer’s brief.

MRP is a process of analyzing the requirements of the business and identifying what resources would be needed to meet these needs. MRP is a simple process for planning and developing an organization’s resources. It identifies what needs will be met by each resource, defines objectives, and sets goals. MRP helps in determining resources required to meet business goals and helps channelize people’s effort.
The most common use case that MRP has is in manufacturing industry where there are requirements that need to be met by various machines. These machines would require specific materials such as steel or plastic in order to make them work correctly. In this scenario, it can be quite difficult for a project manager (PM) to identify all the materials needed on the fly without any specific guidance on how they should be purchased.
Why is MRP important?
MRP, which is done primarily through specialized software, helps ensure that the right inventory is available for the production process exactly when it is needed and at the lowest possible cost. As such, MRP improves the efficiency, flexibility and profitability of manufacturing operations. It can make factory workers more productive, improve product quality and minimize material and labor costs. MRP also helps manufacturers respond more quickly to increased demand for their products and avoid production delays and inventory stockouts that can result in lost customers, which in turn contributes to revenue growth and stability.
MRP is widely used by manufacturers and has undeniably been one of the key enablers in the growth and wide availability of affordable consumer goods and, consequently, has raised the standard of living in most countries. Without a way to automate the complex calculations and data management of MRP processes, it is unlikely that individual manufacturers could have scaled up operations as rapidly as they have in the half century since MRP software arrived.
How does MRP work?
MRP uses information from the bill of materials (BOM), inventory data, and the master production schedule to calculate required materials and when they can be used..
The BOM is a hierarchical list of all the materials, subassemblies and other components needed to make a product, along with their quantities, each usually shown in a parent-child relationship. The finished good is the parent at the top of the hierarchy.
In BOM, inventory items are classified as either independent demand or dependent demand. Independent demand is the finished good at the top of the hierarchy Manufacturers determine its amount by considering confirmed orders and examining market conditions, past sales and other indicators to create a forecast, then decide how many to make to meet the expected demand.
Dependent demand items, in contrast, are the raw materials and components needed to make the finished product. For each of these items, demand depends on how many are needed to make the next-highest component in the BOM hierarchy.
MRP is the system most companies use to track and manage all of these dependencies and to calculate the number of items needed by the dates specified in the master production schedule. To put it another way, MRP is an inventory management and control system for ordering and tracking the items needed to make a product.
Lead time is the period of time between placing an order and it being delivered. It can happen in different ways & depend on various factors.. Two of the most common are material lead time (the time it takes to order materials and receive them) and factory or production lead time (how long it takes to make and ship the product after all materials are in). Customer lead time denotes the time between the customer order and final delivery. The MRP system calculates many of these lead times, but some are chosen by the operations managers and entered manually.
MRP in manufacturing
MRP is essential to the efficiency, effectiveness and ultimately the profitability of a manufacturing operation. Without the right raw materials and components on hand, manufacturers can’t hope to keep up with the demand for products at the optimal cost and quality. They will also be less able to respond to fluctuations in demand by adjusting production.
MRP can also make the later stages of production, such as assembly and packaging, proceed more smoothly and predictably by removing most of the uncertainty over inventory and minimizing the time needed to manage it.
MRP is useful in both discrete manufacturing, in which the final products are distinct items that can be counted — such as bolts, subassemblies or automobiles — and process manufacturing, which results in bulk products, including chemicals, soft drinks and detergent, that can’t be separately counted or broken down into their constituent parts.
Benefits of MRP
The primary objective of MRP is to make sure that materials and components are available when needed in the production process and that manufacturing takes place on schedule. Additional benefits of MRP are:
reduced customer lead times to improve customer satisfaction;
reduced inventory costs;
The company inventory management & optimization process is very important–it’s not just “nice to have” but it’s more important than ever before. By managing both your inventory acquisition, as well as how you store, ship, order and distribute your inventory, you are reducing the risk of stock-outs. What this means for your business is positive impact on customer satisfaction, sales
improved manufacturing efficiency by using accurate production planning and scheduling to optimize the use of labor and equipment;
improved labor productivity; and
more competitive product pricing.
Disadvantages of MRP
MRP has drawbacks, including:
Increased inventory costs: While MRP is designed to ensure adequate inventory levels at the required times, companies can be tempted to hold more inventory than is necessary, thereby driving up inventory costs. An MRP system anticipates shortages sooner, which can lead to overestimating inventory lot sizes and lead times, especially in the early days of deployment before users gain the experience to know the actual amounts needed.
Lack of flexibility: MRP is also somewhat rigid and simplistic in how it accounts for lead times or details that affect the master production schedule, such as the efficiency of factory workers or issues that can delay delivery of materials.
Data integrity requirements: MRP is highly dependent on having accurate information about key inputs, especially demand, inventory and production. If one or two inputs are inaccurate, errors can be magnified at later stages. Data integrity and data management are thus essential to effective use of MRP systems.
MRP can be improved by using advanced planning and scheduling software. The idea is that the software will calculate more accurate and realistic estimates of lead times.. Unlike most MRP systems, APS software accounts for production capacity, which can have a significant impact on availability of materials.
MRP vs. ERP
MRP II not only allows other resources, such as financials, to be included in the planning process but also upholds quality control for products, manages capacity planning and cost effectiveness. Additionally, this tool enhances performance by syncing performance with demand forecasts.
In 1990, Gartner coined the term enterprise resource planning (ERP) to denote a still more expanded and generalized type of material resource planning (MRP II) that took into account major functions of a business, such as accounting. ERP is the predecessor to both MRP and MRP II, which are considered its direct predecessors.
ERP quickly expanded to other industries, including services, banking and retail, that did not need an MRP component. However, MRP is still an important part of the ERP software used by manufacturers.
