Introduction: AI in Machine Maintenance

The benefits of AI in predictive maintenance are significant. It reduces equipment downtime by up to 30-50% and increases equipment lifetime by 20-40%, according to McKinsey. Additionally, it enhances safety by preventing unexpected malfunctions and reduces maintenance costs by ensuring maintenance is performed only when necessary.

Scenario A global leader in industrial machinery aims to leverage AI to reduce downtime, streamline troubleshooting, and empower its technicians to make fast, accurate diagnostics with minimal manual data searching. Here, we present Think-it's approach for an AI-driven solution, a comprehensive tool designed to integrate existing resources—such as service tickets, machine manuals, and CRM data—into a single platform. This solution combines predictive maintenance software and Generative AI for troubleshooting to ensure quicker problem resolution and improved machine reliability.

We’ll walk through how we approach the project from conception to implementation, highlighting each stage.

Benefits of AI in Manufacturing Implementing AI in manufacturing offers numerous benefits, including improved operational efficiency, significant cost reduction, and enhanced predictive maintenance capabilities. These advantages position AI as a transformative force in the industry.

Step 1: Defining the Problem and Setting Objectives

Industrial equipment maintenance is complex, and delays in troubleshooting due to fragmented data sources often lead to prolonged downtime. This required a centralized, scalable tool that can do the following:

• Integrate diverse data sources like manuals, service tickets, and CRM logs to create a single point of reference.
• Enable predictive diagnostics to anticipate maintenance needs before issues arise.
• Provide technicians with an AI-driven copilot that could guide them through troubleshooting processes efficiently.

Through the Internal Copilot, we develop a digital solution that can address these pain points by consolidating technical resources, offering real-time support, and making the entire troubleshooting process significantly faster and more accurate.

Step 2: Solution Design and Architecture

To meet these objectives, we designed a solution centered around a large language model for diagnostics. The Internal Copilot would act as a centralized knowledge base for all diagnostic and repair information, accessible via an intuitive interface on both web and mobile platforms.

Here’s a closer look at the components:

Data Pipeline for Technical Support A data ingestion pipeline to import, process, and store information from a range of sources—PDF documents, CRM logs, and service tickets. This data pipeline transforms the raw information into structured content, optimized for fast access during troubleshooting.

AI-Driven Troubleshooting Solutions At the heart of the Internal Copilot is its Generative AI component, trained to answer technicians’ questions based on extracted data. When users input queries, the Internal Copilot references the knowledge base and responds with targeted, data-backed insights. This AI-driven troubleshooting tool also generates additional diagnostic questions based on the initial query, enabling more refined and accurate issue resolution.

Predictive Maintenance Capabilities The Internal Copilot includes a predictive analytics module that identifies patterns in the data and alerts users to potential issues before they arise. This proactive approach helps maintain equipment performance, prevent downtime, and minimize reactive maintenance efforts.

Role-Based Access and Security For security and compliance, the system was designed with role-based access control, ensuring that only authorized personnel could access certain types of machine data. This control feature aligns with B2B software for industrial automation standards, safeguarding sensitive information while facilitating seamless use across teams.

The next section dives deeper in the logical view of the architecture of the Internal Copilot Application. It explains how the different components are connected.

In the next section, we define the data ingestion pipeline and how the data is ingested from the data sources, cleaned and prepared. It describes the process of extracting relevant information from the data, transforming it if needed, storing it in different formats, formatting it into a structure the LLM can understand and then feeding it to the LLM module for processing and answers generation. This ensures the LLM is trained on high-quality information, improving the accuracy and reliability of its responses. The technologies to satisfy this can include the usage of custom Python scripts, data cleaning libraries (Pandas, NumPy) and ETL tools.

In the next section, we present an architecture to explain how the LLM processing module works to generate the answers to the users' questions.
