The next stage of evolution in manufacturing IT combines MES functionality with artificial intelligence. While traditional MES systems collect and visualize data, AI-assisted MES platforms interpret that data automatically—detecting anomalies, predicting downtimes, and recommending optimizations in real time.
With the upcoming AI Assistant in the SYMESTIC Cloud MES platform, data transparency becomes active decision support.
Traditional MES systems deliver KPIs such as OEE, output, scrap, and downtime.
But they remain descriptive—they show what happened.
AI adds the missing dimensions: why it happened and what will happen next.
Examples of predictive applications:
This turns production control from reactive to proactive.
Machine learning models analyze historical process data to identify correlations between parameters and events.
In the cloud, these models are continuously trained and refined based on real production data.
Typical data sources:
Machine and process signals (OPC UA, PLCs)
Quality and scrap data
Energy and consumption data
Operator input from BDE/MDE systems
Goal: Identify cause-and-effect relationships.
Example: A slightly elevated tool temperature combined with a specific alarm code frequently precedes an increase in scrap. The system learns to recognize this pattern and triggers an early warning.
The interplay between edge connectivity and cloud intelligence is essential.
Edge components capture signals at millisecond latency and buffer data locally.
Cloud models analyze long-term trends, patterns, and probabilities.
Results flow back into the MES as actionable recommendations or automated alerts.
This hybrid architecture enables real-time responsiveness at the shop floor and long-term optimization at the enterprise level.
AI-driven MES delivers measurable economic benefits:
–25 % fewer downtimes through early detection
+15 % higher equipment availability through predictive maintenance
–20 % scrap reduction via anomaly detection
+30 % faster reaction time to process deviations
AI becomes a continuous improvement engine—it not only identifies losses but highlights the most probable root cause automatically.
For AI in MES, explainability is critical.
Every recommendation is based on documented data correlations
Algorithms are versioned and auditable
Users receive transparent insights (“Explainable AI”) rather than black-box outputs
Human control remains central—enhanced by data-driven intelligence.
AI is not an add-on; it will become a core element of MES architectures.
Future systems will:
Not only predict downtime but autonomously initiate countermeasures
Optimize energy and quality metrics simultaneously
Simulate alternative production decisions in real time
This evolution transforms MES from a reporting tool into a cognitive control system.
An AI-assisted MES unites data competence with operational intelligence.
It identifies patterns before they become problems and translates data into action.
From data collection to decision automation—
that is how Manufacturing Execution becomes true Manufacturing Intelligence.
