Introduction
In a groundbreaking collaboration, Daikin Industries and Hitachi, Ltd. are set to revolutionize factory management with an AI agent aimed at diagnosing equipment failures. This innovative initiative is being trialed at Daikin's Sakai Plant in Osaka, which specializes in producing commercial air conditioning units. The practical deployment of the AI diagnostics agent is expected to begin in April 2025, marking a significant advancement in operational technology (OT) and information technology (IT) integration.
Project Overview
The joint effort between Daikin and Hitachi aims to fuse years of operational knowledge with Hitachi's cutting-edge IT capabilities. The AI agent will support maintenance technicians by identifying the causes of malfunctions in equipment such as pumps and valves during inspections carried out with handheld tablets. When a problem is identified, the diagnostic agent swiftly proposes potential causes and remedies to enhance maintenance processes.
How It Works
The operational framework involves Daikin transforming its extensive repository of production equipment diagrams into a format accessible to generative AI, which is capable of interpreting knowledge graphs. By utilizing the generated knowledge graphs alongside OT data and Hitachi's proprietary analysis process — based on the System Theoretic Accident Model and Processes (STAMP) — the AI diagnostics agent aims for a diagnostic accuracy surpassing that of standard maintenance technicians.
Validation of Effectiveness
In preliminary tests, the AI agent demonstrated the ability to identify the causes of equipment failure and suggest solutions with over 90% accuracy within 10 seconds. This remarkable efficiency is a testament to the integration of generative AI with real-world operational data, showcasing how technology can enhance traditional manufacturing processes.
Future Plans
Looking ahead, Daikin and Hitachi intend to complete this trial by September 2025, leading to the full-scale implementation of the AI diagnostics agent across Daikin's production sites both domestically and internationally. The goal is to democratize expertise in equipment maintenance, thus enhancing quality assurance on a global scale, enabling knowledge transfer, and increasing productivity for frontline workers.
Lumada Solutions Expansion
Hitachi plans to scale the AI diagnostics agent as part of its Lumada solutions, expanding its applicability beyond equipment maintenance into other fields. This aligns with their commitment to accelerate digital transformation and improve operational efficiency through a blend of OT knowledge and IT applications. Furthermore, their service offerings include rapid development of AI agents utilizing OT knowledge, with the aim of enhancing the productivity of frontline workers significantly.
Contextual Background
The manufacturing industry is facing significant challenges due to the declining workforce and an increasing need for skilled technicians in a rapidly globalizing environment. Daikin operates over 90 production bases across 28 countries, but the rising demand for skilled maintenance personnel, particularly in overseas locations, is not being met. Consequently, maintenance lead times have increased, and quality has become inconsistent.
Addressing Workforce Challenges
In response, Daikin and Hitachi have previously collaborated on initiatives to digitize skilled trades and processes. By introducing innovative digital solutions, they aim to establish a 'factory without failures' ethos, exemplifying a relentless commitment to improving manufacturing efficiency and sustainability.
