What is MRP? How it helps Demand and Supply.

What is MRP?

At its core, MRP stands for “Material Requirements Planning.” This strategic approach is a cornerstone in modern operations management and supply chain optimization. MRP empowers businesses with the ability to streamline their production processes, enhance efficiency, and make more informed decisions about resource allocation.

What is MRP System?

An MRP system is a digital tool that executes Material Requirements Planning. This software helps businesses maintain a delicate balance between supply and demand by using real-time data and algorithms. By incorporating factors like lead times, inventory levels, and customer orders, an MRP system calculates the exact quantity of raw materials and components needed to meet production goals. This prevents both excess and shortages, reducing waste and ensuring a smoother workflow.

Having a good inventory control with a Manufacturing Resource Planning could be part of MRP system. MRP System consists of managing Economic Order Quantity, dependent demand items, human resources and their capacity, production cycle with scheduling production with manufacturing operations. A good manufacturing process with a good production process with Bills Of Materials, checking material availability with a production capacity would make a difference. A good supply chain management with a customer satisfaction is definite goal for success and retain customers.

What is Material Planning?

Material planning, within the context of MRP, is the systematic process of determining the right amount of materials required for production. It involves analyzing historical data, sales forecasts, and market trends to anticipate future demand accurately. By effectively mapping out material needs, businesses can avoid overstocking, minimize production delays, and ultimately enhance their overall operational efficiency.

How MRP System Helps in Operations Management?

MRP System plays a pivotal role in operations management by offering a structured approach to resource allocation. It ensures that production activities are synchronised with demand (Sales order or master schedule), preventing bottlenecks and promoting a steady production flow.

Focus on the MRP helps for a planning period to reduce inventory costs, increase the control inventory spillage etc. Depending on customer lead times, we can plan to reduce the stock level or increase it. It also affects production lead time and labor productivity as the output could be controlled now.

MRP has a pull affect on the manufacturing sector’s entire supply chains including purchasing plans, schedule production with machine loading etc.

A demand-driven planning with help to improve efficient production planning with multi level advanced planning processes too.

For instance, consider a furniture manufacturer using MRP to align its raw material procurement with customer orders. This prevents the accumulation of excess inventory and minimizes storage costs, thereby contributing to increased profitability.

How MRP Supply Chain Works?

The MRP supply chain process starts with inputting data such as customer orders, existing inventory levels, and lead times into the system. The MRP software then generates a comprehensive production schedule that details when and how much of each material is needed. This schedule ripples through the supply chain, notifying suppliers about the precise quantities required. This level of precision reduces the risk of overproduction or stockouts, fostering a more efficient and cost-effective supply chain.

What is MRP and ERP? What’s the Difference?

MRP and ERP (Enterprise Resource Planning) are closely related but distinct concepts. MRP is a subset of ERP, focusing specifically on the planning and control of materials required for production. ERP, on the other hand, encompasses a broader spectrum of business processes such as finance, HR, and customer relationship management. While MRP primarily deals with optimizing material flows, ERP integrates various departments and functions into a single cohesive system, enhancing overall business visibility and coordination.

MRP System Example

Let’s review an example of how an MRP System operates in a manufacturing company:

Imagine a company called “TechElectro,” which specializes in producing smartphones. The company utilizes an MRP system to ensure efficient production, accurate inventory management, and timely delivery to meet customer demands.

1. Forecasting and Demand Planning: TechElectro’s MRP system starts by analyzing historical sales data, market trends, and upcoming promotions to forecast future demand for their smartphones. This demand planning helps the company anticipate which models will be in higher demand and when.

2. Bill of Materials (BOM): For each smartphone model, TechElectro has a comprehensive Bill of Materials that lists all the components required for assembly – including the screen, processor, battery, camera modules, and more. The MRP system ensures that this BOM is accurate and up-to-date.

3. Master Production Schedule (MPS): Using the demand forecasts and the BOM, the MRP system generates a Master Production Schedule. This schedule outlines the quantities of each smartphone model to be produced over a specific timeframe. For instance, if the forecast predicts higher demand for a particular model, the MPS will reflect increased production for that model.

4. Material Requirements Calculation: The MRP system calculates the exact materials needed based on the MPS, considering factors like lead times for procurement and production. It takes into account the current inventory levels of components and raw materials.

5. Order Generation: As the MRP system identifies shortages or impending shortages of specific components, it generates purchase orders or production orders to replenish the inventory. These orders are automatically triggered by the system when stock levels fall below a predetermined threshold.

6. Supplier Communication: The MRP system communicates with suppliers, sending them purchase orders with detailed specifications and quantities required. Suppliers then deliver the materials to the manufacturing facility based on the agreed-upon lead times.

7. Production Scheduling: The MRP system aligns production schedules with the availability of materials. It ensures that the right components are available when needed, preventing production delays due to material shortages.

8. Inventory Management: As materials arrive, the MRP system updates inventory levels in real-time. It also tracks work-in-progress (WIP) inventory at various stages of production.

9. Order Fulfillment: As production is completed, the smartphones move through the various stages of assembly. The MRP system ensures that the finished products are available in line with customer orders.

10. Reporting and Analysis: The MRP system provides detailed reports on production efficiency, material consumption, lead times, and more. This data helps TechElectro’s management make informed decisions to further optimize their processes.

In this scenario, the MRP system enables TechElectro to maintain optimal inventory levels, minimize production delays, and respond effectively to changes in demand. By ensuring the right materials are available at the right time, TechElectro can produce smartphones efficiently, reduce costs, and ultimately provide customers with timely and high-quality products.
