MES (Manufacturing Execution System) and MOM (Manufacturing Operations Management) are related concepts within the realm of manufacturing, but they serve different purposes and encompass different functionalities: MES (Manufacturing Execution System) is a subset of MOM (Manufacturing Operations Management). MES focuses on executing manufacturing processes on the shop floor, while MOM encompasses a broader range of functions including planning, scheduling, quality management, and more. MES handles real-time monitoring, data collection, inventory management, and quality control to improve efficiency and productivity. MOM involves strategic planning, coordination, and integration across the entire manufacturing lifecycle to align processes with business goals and optimize operations.
