Anomalies are something which any pharmaceutical manufacturer needs to look for during the operation of the manufacturing plant because the slightest change in temperature, pressure, equipment performance, and manufacturing efficiency might become the object of the investigation.
With the amount of data generated at the pharmaceutical facilities increasing along with the use of interconnected devices and sensors, anomaly detection can become one of the most effective approaches to identifying abnormalities.
What Is Anomaly Detection?
Anomaly detection is a way of discovering unusual data, which differs from the data that should be generated under normal operating conditions.
During pharmaceutical manufacturing, anomaly might include the following aspects:
- Unexpected temperature changes
- Abnormal vibrations
- Unusual pressure
- Energy consumption patterns
- Unusual production trends
- Unusual environment
While traditional monitoring systems depend on pre-defined thresholds, AI can help detect more complicated patterns which appear due to interactions between the different data points.
How AI and IoT Interact
Industrial IoT provides all the data for AI-based analytics.
Connected sensors can continuously generate data related to the performance of manufacturing equipment and the manufacturing environment itself. This data can be then processed by analytics platforms and machine learning algorithms.
A simple workflow is the following:
Sensors → Data Collection → AI Analysis → Anomaly Detection → Alert → Human Investigation
Such system creates a continuous feedback loop between the physical manufacturing environment and the digital world.
Applications in Pharmaceutical Manufacturing
Monitoring of Equipment
AI can help discover unusual patterns in the equipment performance data. As a result, the maintenance team will be able to investigate and fix potential problems in time.
Environmental Monitoring
Temperature, humidity, pressure, and other environment parameters can be continuously monitored. Any abnormalities can serve as the signal for further investigation.
Process Monitoring
It is also possible to compare the current manufacturing behavior with the historical one and to find out unusual patterns.
Quality Analysis
Manufacturers can apply the technique of anomaly detection to datasets that contain quality-related information and to discover recurring patterns which require investigation.
Why Does It Matter
AI-based anomaly detection can help companies transition from purely reactive monitoring to proactive operation.
Instead of analyzing large amounts of data manually, teams can pay their attention to the unusual events detected by AI-based systems.
There have been a lot of studies into AI and IoT integration in pharmaceutical manufacturing. Possible use cases include real-time monitoring, predictive maintenance, quality control, and anomaly detection.
Challenges to Consider
First of all, one needs to remember that just the use of machine learning doesn't mean that the system is reliable.
The quality of sensor data is of great importance. It should be correctly calibrated and free of gaps and errors. There may also be some difficulties during integration with legacy manufacturing systems.
The pharmaceutical industry should pay attention to the issues of data integrity, cybersecurity, model validation, and proper human supervision. FDA pointed out the above-mentioned aspects in terms of using AI in pharmaceutical manufacturing.
The Future of Intelligent Manufacturing
As the pharmaceutical facilities become more and more integrated, anomaly detection may become a part of the whole digital manufacturing strategy.
There are many other technologies which can be integrated with AI and create a more complete picture of manufacturing operations, such as Industrial IoT, predictive maintenance, computer vision, digital twins, and real-time dashboards.
It's not about replacing skilled operators or quality professionals but providing them with additional means for detecting important signals and making better decisions.
