Solution Overview
Predictive maintenance solutions can allow organizations to achieve significant operational achievements, such as reducing downtime by 15-20%, increasing labor productivity by 5-20%, and cutting maintenance costs by 30-60%, according to Deloitte.
This solution uses MongoDB Atlas to build an end-to-end predictive maintenance system that helps manufacturers prevent equipment failures and optimize maintenance operations. The solution has four stages:
- Machine prioritization and criticality analysis: Uses ML and RAG-based analysis to determine equipment to prioritize for predictive maintenance. 
- Failure prediction: Uses Atlas Stream Processing to process real-time sensor data and detect potential failures before they occur. 
- Maintenance plan generation: Uses LLMs trained on maintenance manuals, inventory data, and resource information to automatically generate detailed work orders for failure situations. 
- Maintenance guidance generation: Generates enhanced maintenance guidance and uses Change Streams to deliver instructions directly to technicians' mobile devices.

Reference Architectures
This section guides you through the architecture of each stage in this solution.
Machine Prioritization and Criticality Analysis

This stage uses RAG to determine which machines require predictive maintenance. The system processes two types of input data:
- Structured data, such as production parameters and machine breakdown frequency. 
- Unstructured data, such as institutional knowledge stored in PDF documents. 
The workflow aggregates and operationalizes both data types as vector embeddings in MongoDB Atlas, then uses Vector Search to semantically search the database. The results of the search provide relevant context to an LLM, via Amazon Bedrock or Cohere, which generates responses to prioritization queries. This helps maintenance teams make data-driven decisions about which machines need attention first.
Failure Prediction

This stage processes real-time machine sensor data for failure prediction through six key stages:
- Data collection: A prioritized machine captures metrics such as product type, temperature, speed, and tool wear. 
- Stream processing: The system transforms the raw sensor data. 
- Data storage: The data is stored in MongoDB Atlas. 
- Change detection: Change streams monitor the data for significant changes. 
- ML inference: A trained model predicts potential failures. 
- Dual output: Atlas Charts visualizes the data, and Change Streams enable mobile notifications. 
Maintenance Plan Generation

This stage automates maintenance work order creation through the following architecture:
- Document processing: The solution splits machine manuals and old work orders into chunks and converts them to vectors using Cohere embedding models. 
- Vector storage: The solution stores embeddings in MongoDB Atlas. 
- Work order generation: A specialized app uses LLMs to generate work order templates, pulls inventory and resource information through an aggregation pipeline, and creates detailed repair plans. 
Maintenance Guidance Generation

This stage uses RAG to enhance operator instructions with the following architecture:
- Service note processing: Converts multilingual PDF service notes to text. 
- Translation: Processes non-English content through translation models. 
- Instruction generation: Uses LLMs to combine translated service notes with original repair plans. 
- Delivery: Provides updated maintenance instructions to technicians through a mobile app.
