What Is Material Requirements Planning (MRP)

Material requirements planning (MRP) is a digital inventory management system that can be accessed through a variety of computer-based platforms. MRP is specifically developed to increase a company’s inventory efficiency by estimating raw material amounts and arranging timely deliveries. A Material Requirements Planning (MRP) system is a production planning and decision-making tool that compares current inventory levels to production capacity and the need to make goods based on projections. MRP plans output according to bills of materials while reducing inventory.  

Processes and Steps in the MRP

The MRP procedure is divided into four major steps:

  1. Recognizing requirements in order to meet demand

 Identifying client demand and the requirements needed to meet it is the first phase in the MRP process, which begins with processing customer orders and sales predictions.


  1. Inventory control and resource allocation

 You can monitor what things you have in stock and where they are by using the MRP to compare demand against inventory and allocating resources accordingly. This is especially significant if you have inventory in multiple locations. This also allows you to examine the status of products, giving you insight into items that have already been assigned to another project, as well as items that are in transit or on order but are not yet physically in the warehouse. The MRP then moves goods to the appropriate areas and suggests reordering.


  1. Production scheduling

 The system determines how much time and labour are required to finish each phase of each build, as well as when they must occur, so that production may proceed without delay, using the master production schedule. The production schedule also determines which machines and workstations are required for each phase, as well as the work orders, purchase orders, and transfer orders that are required.   

  1. Identifying problems and giving suggestions

 Finally, because the MRP connects raw materials to work orders and customer orders, it can automatically notify your team when items are late and make recommendations for current orders, such as moving production in or out, performing what-if analyses, and generating exception plans to complete the required builds.


 MRP’s Advantages

When considering implementing an MRP inventory system within a company, it’s critical to understand the benefits and drawbacks of doing so. The following are some of the advantages:

  •         Maintains a low level of inventory
  •         Material planning allows for a reduction in associated expenditures.
  •         Ensure that capacity is being utilized.
  •         Every piece of inventory that comes in and goes out is meticulously tracked.
  •         Product warehousing costs are reduced.
  •         Organizational improvements across the board
  •         The items will be shipped and delivered on time.


MRP’s disadvantages

The following are some of the drawbacks of adopting a material requirement planning inventory system:

  •         Continuation of reliance on precise input data.
  •         If information is entered incorrectly into the system, there are delays in scheduling, incorrect order quantities, and ineffective tracking.
  •         Extensive database maintenance is required.
  •         It is necessary to receive sufficient training in order to operate the system.
  •         The system is expensive, and it necessitates a significant financial commitment.


Final Verdict

An MRP system enables a company to achieve a number of advantages that not only save costs but also improve the efficiency of its production system. To maintain cost effectiveness and efficiency, the system assists you in calculating future capacity needs, planning production times, establishing essential safety stock, and determining the most convenient lot sizes. The correct usage of an MRP system necessitates the keeping of reliable records in order to ensure that you have accurate data to submit into the system.
