Artificial intelligence has dominated headlines for months. However, many manufacturing companies are still asking a far more practical question than a technological one: what is AI actually used for in the day-to-day operations of a factory?
We’re not talking about flashy demonstrations or futuristic scenarios. We’re talking about challenges that every production, maintenance, quality, or continuous improvement manager knows all too well.
- Finding the root cause of an issue.
- Locating technical information when a machine goes down.
- Interpreting thousands of production data points to make better decisions.
- Resolving equipment failures more quickly.
- Preparing quality documentation.
- Guiding operators through complex manufacturing processes.
Most of these challenges existed long before artificial intelligence. What is changing now is not the problem itself, but the time it takes to understand and solve it.
What is artificial intelligence in manufacturing?
Artificial intelligence in manufacturing involves using AI models connected to the data, processes, and operational knowledge of a production facility to help teams interpret information, resolve issues, automate repetitive tasks, and make better decisions.
On its own, AI does not improve a factory. Its real value comes from working with reliable data, understanding the production context, and integrating seamlessly with the systems already used in day-to-day operations, such as a Manufacturing Execution System (MES).
That is why, before exploring practical AI use cases or discussing which manufacturing processes can be improved with AI, it is worth revisiting two key concepts we have previously covered on the Mapex blog.
First, the quality of AI outcomes depends on the quality of the underlying data. Without a robust data collection and management strategy, any AI initiative will have limited impact.
Second, technology alone does not transform an organization. Successfully adopting AI also requires preparing people, training teams, and managing change effectively so the technology delivers measurable business value.
AI in manufacturing: practical AI and MES use cases on the factory floor
The table below summarizes some of the most valuable AI applications across different areas of a manufacturing plant.
Most importantly, these are not theoretical examples. They are real-world AI applications that we have developed—or are currently developing—in collaboration with manufacturing companies using the Mapex MES platform.
Some are already deployed in live production environments, while others represent the next generation of solutions we are currently building. We explain each of them in more detail below.
| Department | Common Challenge | How AI Helps |
|---|---|---|
| Production | Large amounts of scattered information. | Queries production data using natural language, generates charts, and explains performance deviations. |
| Continuous Improvement | Finding the root cause of a problem requires hours of analysis. | Automatically correlates production, quality, maintenance, and traceability data to generate root cause hypotheses. |
| Maintenance | Knowledge is spread across manuals, procedures, and technicians’ experience. | Centralizes organizational knowledge and assists technicians in troubleshooting equipment failures. |
| Quality | Preparing quality documentation is time-consuming. | Generates draft control plans and inspects labels using AI-powered image recognition. |
| Operations | Operators constantly need to consult technical documentation. | Provides step-by-step guidance throughout manufacturing operations. |
1. When finding an answer takes longer than solving the problem
One of the biggest challenges in any manufacturing plant is not a lack of information. In fact, it’s quite the opposite.
The data exists, KPIs are available, and reports are readily accessible. Yet answering what seems like a simple question often requires opening multiple reports, exporting data, consulting different departments, or relying on a technical specialist to build a query.
As a result, many manufacturers spend more time searching for information than making decisions.
This is where artificial intelligence begins to transform the way people work.
Instead of navigating multiple dashboards or building complex queries, anyone can ask questions in natural language.
- Which production line experienced the most downtime this week?
- Why did the night shift OEE decrease?
- Which products have the highest rejection rate?
AI doesn’t just retrieve information. It also analyzes production data, identifies patterns, explains anomalies, and generates visualizations that make decision-making faster and easier.
Across several projects developed by Mapex, this capability is already transforming large volumes of industrial data into charts, dashboards, and actionable insights for production managers, quality teams, and plant leadership.
One of our most exciting developments goes even further. When a complex issue arises, identifying the root cause typically requires analyzing information from production, maintenance, quality, traceability, and other business systems.
We are developing specialized AI agents capable of automatically correlating all these data sources, generating hypotheses, and helping users identify the most likely root cause through a single conversation.
The goal is not to replace human expertise, but to dramatically reduce the time spent investigating production issues.
2. Maintenance knowledge shouldn’t depend on one person
Many manufacturing plants face a hidden challenge: the information needed to resolve equipment failures exists, but it is scattered across OEM manuals, internal procedures, wiring diagrams, images, historical documentation, and the experience accumulated by maintenance technicians.
When a breakdown occurs, finding the right information can take longer than the repair itself. This was precisely one of the challenges presented by Industrias Teixidó.
The objective was to build a centralized knowledge base that consolidated all maintenance documentation and enabled technicians to find the information they needed without knowing where it was stored.
To achieve this, it was necessary to collect, organize, and prepare all documentation, implement semantic search technologies, and integrate everything with Maik, Mapex’s AI assistant, so it could understand technicians’ questions and respond using the appropriate operational context.
The result was intelligent maintenance support during troubleshooting, providing instant access to procedures, manuals, diagrams, and technical documentation.
The benefits were clear: faster issue resolution and a lower MTTR (Mean Time to Repair) thanks to much quicker access to maintenance knowledge.
3. Quality: automating repetitive tasks to focus on preventing errors
Quality departments manage an enormous amount of technical documentation.
Interpreting engineering drawings, preparing control plans, reviewing specifications, verifying labels, and ensuring every requirement is met are essential tasks—but they are also repetitive and highly time-consuming.
AI can automate a significant portion of these activities.
For example, it can automatically analyze engineering drawings and technical documentation to generate initial control plan proposals tailored to each organization’s internal quality standards.
Quality specialists still validate the final result, but they no longer have to start from scratch.
Another example is AI-powered visual inspection. AI can automatically verify that the labels used during production are correct, detecting inconsistencies before products leave the production line and reducing the risk of shipping or traceability errors.
Artificial intelligence does not replace the expertise of quality professionals. Instead, it frees them to focus on the decisions where their knowledge creates the greatest value.
4. Intelligent assistance during production operations
Not every production issue is caused by a lack of knowledge. In many cases, operators simply need to consult work instructions during an operation, but the information is not easily accessible.
This becomes especially important in environments with multiple product variants, frequent changeovers, or complex manufacturing processes, where having the right information at the right moment can make all the difference.
AI makes it possible to transform all that documentation into an interactive assistant capable of guiding operators step by step throughout each operation.
Instead of searching through multiple documents, operators can ask the assistant directly. It responds using only company-approved documentation while adapting the instructions to the specific production context.
This improves work standardization, reduces errors, and accelerates employee onboarding without requiring any changes to existing procedures.
5. The next step: AI agents that act on production issues
Until now, most artificial intelligence applications have focused on interpreting information or assisting people.
At Mapex, we are evolving our AI assistant so it can also operate as an intelligent agent within the MES platform.
The objective is for it to detect production issues, trigger response workflows, coordinate information across multiple systems, and track every incident until it has been successfully resolved.
In this scenario, AI moves beyond simply answering questions and begins actively collaborating in the execution of industrial processes, always within a controlled framework aligned with the company’s operating procedures.
This evolution is still under development, but it represents one of the most promising directions for the future of manufacturing.
What artificial intelligence does not do in a factory
It’s tempting to think that AI can solve every problem on its own. The reality is very different.
Artificial intelligence does not replace:
- The experience of production operators.
- The expertise of production managers.
- A well-defined data strategy.
- Continuous improvement processes.
- Human decision-making.
What AI does is reduce the time required to access organizational knowledge, analyze production data, identify patterns, and accelerate problem-solving.
What we’ve learned from implementing AI in manufacturing
After developing AI solutions alongside manufacturing companies, several key lessons have consistently emerged.
First, the greatest value comes from making the knowledge that already exists within the factory easily accessible.
Second, AI delivers the best results when it is integrated with the MES and works with reliable, contextualized production data.
Third, the first successful AI projects typically focus on very specific use cases, such as maintenance, production data analysis, or quality management. Solving a well-defined business problem drives far greater adoption than introducing AI as a generic technology.
