MES (Manufacturing Execution System) and MRP (Material Requirements Planning) are two of the most important tools used in business settings to maximize efficiency, save money, and increase profits. MES is an essential part of modern manufacturing operations that allow companies to plan, manage, store, and report on all aspects of their production process. It has the ability to track production in real time and provide accurate data regarding materials, labor, and other resources used in the process. MRP can be thought of as a subset of MES that focuses on planning resources required for the production process. It takes into account the actual resources available and generates schedules that balance the production process with the allocated resources. Together, MES and MRP ensure smooth operations and cost savings across an organization.
