What is MES (Manufacturing Execution System)?
This article introduces MES — a system that plays a critical role in managing production operations on the shop floor.
MES (Manufacturing Execution System) is a “production execution system” that supports and directs frontline personnel. It helps manage and monitor manufacturing processes in real time. In essence, MES controls and organizes operational data that directly drives shop floor production.
Three Layers of Manufacturing Management
Manufacturing operations are typically structured into three levels:
- Planning Level : Strategic planning and scheduling of production activities.
- Execution Level : Real-time operations and coordination of production tasks.
- Control Level : Monitoring and adjustment of machinery and processes to ensure optimal performance.
Functional Overview of MES by MESA International
MESA International, a U.S.-based organization that defines MES standards, categorizes MES functionality into 11 key areas:
- Resource Allocation & Status
- Operation/Detailed Scheduling
- Dispatching Production Units
- Document Control
- Data Collection
- Labor Management
- Quality Management
- Process Management
- Maintenance Management
- Product Tracking & Genealogy
- Performance Analysis
Applying these functions appropriately allows manufacturers to manage, improve, and optimize shop floor operations in terms of Quality, Cost, and Delivery.
