Predictive Maintenance with Agentic AI Systems

By Boris Bialek, Vice President, MongoDB

The manufacturing sector is navigating a growing number of challenges: evolving customer demands, intricate software-mechanical product integrations, just-in-time global supply chains that become challenging (again), and a shrinking skilled labor force. Meanwhile, the entire industry is working under intense pressure to improve productivity, manage energy consumption, and keep costs in check. To stay competitive, the industry is undergoing a digital transformationโ€”and data is at the center of that shift.ย 

Generative AI based on data-driven manufacturing offers a powerful answer to many of these challenges. Utilizing existing sensorics, and a broad variety of data sources ranging from enterprise resource planning (ERP) for production to machine specific temperature sensors brings the opportunity to drive new concepts, making the original thought of a Digital Twin so much more valuable.ย ย 

Picking one prime example: on the shop floor, one of the most critical and high-impact applications of these strategies is predictive maintenance. Downtimeย isnโ€™tย justย inconvenientโ€”itโ€™sย expensive. Every unproductive hour in the automotive sector now costs $2.3 million (Siemens,ย The True Cost of Downtime 2024). For manufacturers across all sectors, predictive maintenance is no longer optional, but the foundation of operational excellence and profitability.ย 

At its core, predictive maintenance is about using data toย anticipateย machine failures before they happen. It began with traditional statistical models, evolved with machine learning, and is now entering a new era of more advanced approaches, including generative AIย with retrieval-augmented generation (RAG)ย capabilities. Manufacturers builtย RAG basedย solutions focused on enabling faster access to repair, with data from maintenance manuals and then linked to sensors on user/maintainer interactions. While this was originally considered groundbreaking, it became clear that these solutions areย reactiveย versusย proactive.ย ย 

The next frontier is multi-agent systemsโ€”AI-powered agents working together toย monitor, reason, and act. Agents take real-time operational data and mesh it with existing sources to understand the state of a device orย component. They use generative AI for real-time signal processing, encompassing all stages: embeddings, vector search, LLM retrieval, and result reranking.ย ย A set of agents acting as a โ€œDigital Expertโ€ can now process like a human from a top lineย objectiveย (โ€œMaximize the operational uptimeโ€) toย a partition of single decision items (โ€œKeep the temperature of the cutting tool at or below 200Cโ€). Each agent thenย is goingย through three phases:ย 

  1. Perceive: The agent receives context and prior information collected andย preparedย for potential tasks. This could include data on average temperatures, age ofย toolsย and other information.ย 
  2. Decide: The agent puts the prior information and the actual input signals for the specific item (โ€œEnsure optimum parameters for the cutting toolโ€) into context.ย 
  3. Act: The agentย takes actionย based on the inputs and the LLM response,ย initiatingย changesย whereย needed (โ€œReduce cutting speed byย 10millimetersย per secondโ€).ย ย 

One of the key components for this concept is the real-time capability of accessing any of the relevant data, along with the ability to act. This is where the database and theย memory of the agentย come into play. For the Digital Expert, its โ€œmemoryโ€ is comparable to the learning experiences humans โ€œsaveโ€ in their brain. Some memories are short term, such as the immediate parameters to be set in the actualย context,ย other memory is long term and focuses on the bigger picture, like the best operational condition for a cutting tool based on historical evidence.ย ย 

On the shopย floorย agents can automate inspections, re-optimizeย production schedules,ย assistย with fault diagnostics, and more. According to aย LangChainย survey, 78% of companies are actively developing AI agents, and over half already have at least one agent in production. Manufacturing companies can especiallyย benefitย from agentic capabilities acrossย a great varietyย of practical use cases.ย

Leveraging AI agents in industrial environments presents unique challenges. Integration with industrial protocols like Modbus or PROFINET is complex; governance and security requirements are strict, especially when agents interact with production equipment. Latency is also a concern as AI models need fast, reliable data access to support real-time responses. And furthermore, the immense volumes of data that agents generate and consume requires companies to sustain a data foundation that is reliable and thatย can quickly scale without sacrificing performance.ย 

Many of these challenges are not new to manufacturersโ€”and the introduction ofย document-basedย databases delivers a provenย track recordย of addressing them. Today, industry leaders in the manufacturing and automotive industries are using document-based databases to power critical Internet of Things (IoT) and telemetry use cases.ย Bosch, for example, uses a document-based database to store, manage, and analyzeย huge amountsย of data to power its Bosch IoT Insights solution. The flexible document model is the ideal data storage solution for diverse sensor inputs and machine telemetry becauseย it seamlessly enables systems to iterate and evolve quickly.ย 

So, what would an agentic system look like for predictive maintenance in the manufacturing industry?ย Letโ€™sย take a lookย at some of the possible components for building such a solution on a document database.ย ย 

Building a multi-agent predictive maintenance systemย 

This solutionย demonstratesย how to build a multi-agent predictive maintenance system using a NoSQL document database, an agent orchestration framework, and a managed service for foundational models. This system can streamline complex processes, such as detecting equipment anomalies, diagnosing root causes, generating work orders, and scheduling maintenance. Atย a high level, this solutionย leveragesย the document database as the unified data layer. The agent orchestration framework provides the coordination layer, enabling graph-based interaction among different specialized agents, while the managed service for foundational models powers the underlying LLMs used by the agents to reason and make decisions.ย 

The architecture follows a supervisor-agent pattern. The supervisor coordinates tasks and delegates to three specialized agents:ย 

  • Failure agent: which performs root cause analysis and generates incident reports.ย 
  • Work order agent: which drafts maintenance work orders with detailed requirements.ย 
  • Planning agent: whichย identifiesย theย optimalย time slot for the maintenance task based on availability and production constraints.ย

This modular design enables the system to scale easily and adapt to different operational needs.ย Letโ€™sย walk through the full process in four key steps.ย 

Step 1: Failure prediction kicks off the agentic workflowย 

The process begins with an alertโ€”something unusual in theย machineย data or logs that could point to a potential failure. The databaseย providesย a unified view of operational data, real-time processing capabilities, and seamless compatibility with machine learning tools. Sensor data is processed in real-time and integrated with ML inference models.ย All whileย the downstream applicationsย remainย up to date with the latest notifications and dashboards. From there, the supervisor agent takes over and coordinates the next steps.ย 

Step 2:ย Leverageย your data for root cause analysisย 

The supervisor notifies the failure agent about the alert. Manual diagnostics of a machine can take hoursโ€”sifting through manuals, historical logs, and environmental data. The AI agent automates this process. It collects relevant documents, retrieves contextual insights using vector search, and analyzes environmental conditions stored in the databaseโ€”like temperature or humidity at the time of failure. With this data, the agent performs a root cause analysis and proposes corrective actions. It generates a concise incident report and shares it with the supervisor agent, which then moves the workflow forward.ย 

Step 3: Work order process automationย 

The work order agent receives the incident report and drafts a comprehensive maintenance work order. It pulls fromย previousย similar tasks to estimate time requirements,ย identifyย the necessary materials, and ensure the right skill sets are listed. All of this is pre-filled into a standardized work order template and saved back into the database. This step also includes a human-in-the-loop checkpoint. Technicians or supervisors can review andย modifyย the draft before it isย finalized.ย 

Step 4: Finding theย optimalย maintenance scheduleย 

Once the work order is approved, the planning agent steps in. Its task is to schedule the maintenance activity without disrupting production. The agent queries the production calendar, checks staff shift schedules, and verifies inventory availability for required materials. It considers alert severity and rescheduling constraints to find the most efficient time slot. Once theย optimalย window isย identified, the agent sends the updated plan to the scheduling system.ย 

While weย focusedย on a predictive maintenanceย workflow, this architecture can be easily extended. Need agents for compliance reporting, spare parts procurement, or shift planning? No problem. With the right foundation, the possibilities are endless.ย 

Unlocking manufacturing excellence with Agentic AIย 

Agentic AIย representsย a new chapter in the evolution of predictive maintenance, enabling manufacturers to move from reactive responses to intelligent, autonomous decision-making. By combining AI agents with real-time telemetry and a unified data foundation, teams can reduce downtime, cut maintenance costs, and boost equipment reliability. But toย work atย scale, these systems need flexible, high-performance infrastructure. With native support for time series data, vector search, stream processing, and more,ย document-basedย databases make it easier to build,ย operate, and evolve multi-agent solutions in complex industrial environments. The result is smarter operations, greater resilience, and a clear path to manufacturing excellence.ย
