Three ways that AI can offer value in plants.
We’ve been working on solving a variety of customer issues. Of the issues that couldn’t be solved with conventional analysis methods, we were able to solve 50 by applying AI. We learned that in plants AI can offer value in the following three ways.
Abnormal Sign Detection
Predicts various equipment failures and plant shutdowns. Enables you to perform maintenance before an abnormality occurs, take countermeasures in advance, and improve your uptime.
Root Cause Analysis
Ascertains the causes of previous problems, and identify the cause of reduced quality and changes in consumed power. By identifying the areas of focus when improving and implementing quality measures, you can improve product quality.
Assigns quality indexes, predicts quality before testing, and predicts changes in quality. Get a handle on quality without destructive testing and other processes that take time to test, and reduce costs.
Results from YOKOGAWA AI solutions
These are some of the analysis results from AI solutions that YOKOGAWA has offered.
We have been solving customers’ issues in many industries including oil refineries and chemical plants using our AI.
Abnormal Sign Detection
-Quickly detects Anomality in equipment-
A shaft breakage occurred in a reducer that monitored trends with a wireless vibration sensor (Sushi Sensor). The graph below shows acceleration, speed, and surface temperature data, and the results of AI analysis based on those data. The moving average of health index calculated by AI moved from the normal to abnormal range three weeks before a failure. You can see that it captured the “Anomality” that were signs of abnormality earlier than the sensor data trend changes. By combining the Sushi Sensor with the AI, undesired state can be notiﬁed based on the equipment's vibration and surface temperature data, which enables you to predictively detect equipment abnormality and to take prior actions for equipment maintenance.

AI on a stand-alone computer detects predictive abnormality sign of equipment
with Anomaly Detection,
AI analysis data logging software GA10 + Sushi Sensor
In recent years the need for maintenance is growing as equipment ages. Equipment conditions are mainly ascertained by human workers through inspections such as operator rounds inspection. However, we face the problems of declining birthrates leading to labor shortages, and the retirement of skilled workers leading to skill shortages. Also, the measured results obtained through an operator rounds inspections are not quantified, and often cannot be utilized effectively. We urgently need to create more efficient equipment maintenance mechanisms.
Automatically detects the “anomalies” that are signs of abnormalities
GA10 + Sushi Sensor are equipment predictive maintenance solution that is just like an AI operator, detecting the "anomalies" that are signs of abnormality, and automatically notifying the user.
You can dispatch worker to equipment that needs maintenance at just the right time, this reduces equipment inspection man-hours, lets you quickly discover abnormal signs, and prevents unanticipated equipment shutdowns. You realize more efficient equipment maintenance and increased plant availability.
*Sushi sensor: Up to 1000 units can be registered. (Gate Sushi function; option)
Predict the future with AI New
Use acquired data to predict future data, and display predicted future waveforms along with real time data on the trend screen. You can also set alarms against predicted data to detect problems in advance when they occur in the future so you can deal with them beforehand.
GA10 Data Logging Software - AI notifies you of anomalies
What is GA10?
GA10 is PC-based data logging software that connects various devices installed in factories and premises (such as Sushi Sensor, recorders, and data loggers) through an Ethernet network, and performs monitoring and recording.

-Plant control with AI and reinforcement learning-
Yokogawa has developed the technology to use AI to directly control equipment through reinforcement learning.
Reinforcement learning is one type of machine learning in which AI learns from its own trial and error. The key feature of Yokogawa’s reinforcement learning technology making it so practical is that it can learn with a small number of trials.
Issue with a complex process
- Indicated values are destabilized due to disturbances, resulting in loss of raw materials.
- Skilled workers have difficulty passing on control adjustment technology, requiring time and labor.
- Destabilization of process and decrease in quality due to unfamiliar control methods.
Features of Yokogawa Electric’s reinforcement learning
- The AI teaches itself, and doesn’t require large amounts of teaching data.
- Learns with a small number of trials.
- Optimized with reinforcement learning technology specialized for the control field.

In under 4 hours of learning, it found the ideal control method to eliminate the overshoots that occurred previously.
GA10 is PC-based data logging software for monitoring and recording data by connecting to devices distributed in a factory. Now with an AI-based Anomaly Detection function, the AI notifies you of anomalies before equipment abnormalities occur.
AI development is not that difficult! This tutorial video shows you how to develop AI application on e-RT3 F3RP70 by running AI sample program available on Partner Portal.
