Introducing Explainable AI
Manufacturers are using AI (Artificial Intelligence) to provide high-quality service and products. Explainable Artificial Intelligence
in manufacturing improves efficiency, workplace safety, and customer satisfaction by automating their tasks. The manufacturing industry uses AI in its applications, such as Predictive Maintenance, anomaly detection, real-time quality monitoring, and supply chain optimization. But implementing AI in the manufacturing industry is a challenging process.
What are the Challenges of Implementing AI?
Challenges of Implementing AI in the manufacturing industry are listed below:
- Collect correct data.
- Justifying the working model process.
- Justifying and validating the generated output of the system.
- Strategies Implementation.
- Computing Power.
Most of the AI systems use black-box approaches to get accurate and correct results. But due to complexity and less transparency in the systems, it has a lack of accountability in the decision-making process.
The solution to this opaque nature of models is a white-box model. White-box models generate transparency and empower the developer and Customer to execute complex projects with confidence and certainty.
White-box models provide clear explanations of their behavior, such as
- How do they produce predictions?
- What variables influenced the model?
- Is the decision made by the system correctly or not?
Due to their transparent inner-working model process becomes easily interpretable.
Explainability is essential in the manufacturing industry. White box models provide significant benefits. It allows them to build the trust of their customers.

Why is Explainable AI in Manufacturing Industry Necessary?
The need for Explainable Artificial Intelligence in manufacturing by a case study of Predictive Maintenance (PdM) scenario for manufacturing. This process can save a lot of money and time by reducing and predicting machine breakdown. It can predict machine errors or tool failures.
"A factory loses between 5% and 20% of its manufacturing capacity due to downtime"-According to the International Society of Automation."
Traditionally machines are required to be repaired after a particular interval of time or usage for preventive maintenance processes. However, it still results in significant equipment failure instances resulting in idle workers, lost revenues, and customer trust loss. Besides, it may replace parts that still have a significant working life, wasting time and money.
AI-based Predictive Maintenance uses various data and determines which components should be replaced before they break down. Models can look for patterns in data that indicate failure modes for specific components. Thus it generates more accurate predictions of the lifespan for a component. When specific failure signals are observed, or component aging criteria are met, the components can then be replaced during scheduled maintenance.
These replacement and maintenance cost high. Therefore, it is necessary that the System would provide correct and reasonable results. Therefore Explainable AI is required to know the mistakes that the System can make and the safety measures.
Principles of Explainable AI in Manufacturing
To implement Explainable Artificial Intelligence in our AI system, it should obey four principles of Explainable Artificial Intelligence. These are listed below in brief:
According to this principle, the System will provide a reason for each decision. The predictive maintenance system will tell that an error or tool failure will occur and need maintenance or equipment replacement. It costs a lot for maintenance and replacement. Their customer can query whether the outcome that is generated by the System is correct or not. In explanation, the System will focus on the three major questions: these three factors help to create the output.
- What algorithm is being used?
- How does the model work?
- Which inputs or parameters of the data are taking part in determining an output?
These questions help to understand whether the System is working correctly or not. So they can make decisions whether they will use that System or not. They can also give the reason for the output.
The explanation that the system providing is meaningful. Information will be understandable by the targeted user. The System provides different explanations for different user groups, for the end-user and the developers according to their prior knowledge and experience. If a user can understand the information, it means it is meaningful. The explanation that the System provides should be understandable to the targeted recipient. For example, the System explains the model's inner working and algorithm to debug the System easily. And also understand whether it works correctly or not. But for the developer, they require how the System reaches its decision, so for them, justification of the model through SHAP can be provided. That can gain their trust over the System.
This principle states that explanations should be accurate. Our System explains the same procedure the AI system used to generate output. Because if it generates the wrong output, then it is of no use. False justification can lose a customer's trust and reduce revenue by taking wrong decisions and actions. We should use the correct tool and correct way to represent the explanation of the System.
Knowledge limits prevent the System from giving an unjust and fallacious result. Hence users can assure that the System will never mislead. It will merely show the outcome that will be set for the System. For example, it may be possible that the System will get a different feature or scenario rather than giving false results about which System should tell that this data is wrong. Handling this System can be designed as if the System encounters a different situation and can generate results "out of the topic case."

What are the Features of AI in the Manufacturing Industry?
- Customer Satisfaction: It is necessary to provide customer satisfaction to improve the customer experience. Companies must deliver proactive, seamless, and personalized services to their customers to enhance their experience.
- Trust: Explanation is required for the decision-maker to trust the system. The degree of confidence in the system to decide and the factors that influence its decision must be explained. A completely transparent system can place the Customer's faith in their system. It is hard to provide such transparency in opaque models, but some can use alternatives to clarify them.
- Fairness: Fairness is a must to remove the bias for the system. It is a central requirement of the system. Most of the time, the system would be biased due to an improper dataset. It should be evaluated to check the fairness. Various measures can be used to make a fair dataset, such as resampling and calibration.
- Transparency: Transparency is a major feature that Explainable AI provides. The transparent nature of the AI system helps to understand that and also trust in that.
What needs to be explained?
Justification of the model's output is not enough to solve all customer's queries. It is required to explain every factor of the AI system.
Data: It explains the data collected from IoT sensors embedded in machine equipment, machine operations, environment, etc., used in the Manufacturing industry's AI systems, their correlation, and EDA (Exploratory Data Analysis) to understand the hidden data patterns behind the data. It tells how the data is to be used for the AI system.
Algorithm: The System explains the algorithm used for the System and its comparison to other algorithms.
Model: It provides a detailed explanation of model performance and working in a user-friendly manner so that customers can track the performance of their systems.
Output: Justifies the System's decision, such as predictive maintenance, that the System says that component1 of a particular machine needs to be replaced.
