From forecasting customer demand to ensuring timely fulfillment, MRP plays a pivotal role in driving supply chain success. Join us as we unveil how MRP can revolutionize your supply chain in this blog post.


What is MRP?

In basic terms, MRP software is a system that uses information about projected demand for finished products to calculate the necessary components and raw materials needed to meet that demand. By planning production in this way, businesses can avoid stock-outs, overproduction, and other inefficiencies that can negatively impact their bottom line.


MRP systems were originally developed for manufacturing environments where individual components are assembled into finished products according to a pre-determined schedule. However, the principles of MRP can be applied to any business that needs to manage inventory levels, including retailers, distributors, and service providers.


To understand how MRP works, thinking about the supply chain as a series of interconnected pipelines is helpful. Raw materials enter one end of the pipeline and finished products come out the other end. In between there are various stages of production where components are assembled and then shipped to the next stage in the process.


At each stage in the pipeline, there is a certain amount of inventory that needs to be maintained to keep the production process running smoothly. This is where MRP comes in. By tracking projected demand for finished products, MRP systems can calculate how much inventory needs to be kept on hand at each stage of production.


This information is then used to generate purchase orders for raw materials and components as well as production plans for finished goods. In this way, businesses can ensure that they have the right level of inventory at the right time to meet customer demand.

How MRP Works in the Supply Chain

In a typical manufacturing company, many different departments must work together to ensure the smooth production of goods. The materials management department is responsible for procuring the raw materials needed for production, while the production department is responsible for transforming those raw materials into finished products. In between these two departments is the MRP department, whose job is to ensure that the right amount of raw materials is delivered to the production department at the right time.


MRP works by first creating a master schedule that outlines all of the products that need to be manufactured in a given period. This schedule considers both customer demand and the company’s inventory levels. From this master schedule, the MRP system then creates a series of individual plans for each raw material needed for production. These plans detail when each raw material should be delivered to the production department and in what quantity.


The MRP system constantly monitors both customer demand and inventory levels to make sure that production is always running smoothly. If customer demand increases or inventory levels decrease, the MRP system will automatically adjust its plans accordingly. This ensures that there are never any disruptions in production due to a lack of raw materials.


The MRP system is an essential part of any manufacturing company’s supply chain. By ensuring that the right amount of raw materials is always delivered to the production department at the right time, MRP helps to keep production running smoothly and efficiently.
