Daikin and Hitachi begin trial operation of AI agent supporting equipment failure diagnostics in factories
D aikin Industries and Hitachi are working through collaborative creation to begin a trial operation in April 2025 at the Sakai Plant-Rinkai Factory( Sakai City, Osaka Prefecture) where Daikin manufactures commercial air conditioning equipment. Their aim is to commercialise an Al agent that supports equipment failure diagnostics in factories.
This initiative takes the OT knowledge cultivated by Daikin and Hitachi at their respective worksites over many years and unites it with Hitachi’ s advanced IT. When a maintenance technician armed with a tablet device discovers a failure in a pump or valve while inspecting production equipment, the‘ Al Agent for Equipment Failure Diagnostics’ will indicate the cause and needed corrective actions to the technician. The system works by first converting the factory equipment drawings that Daikin has accumulated, such as various production and utility equipment, into knowledge graphs that the Generative Al can read. Then, the generative Al learns the‘ OT data,’ which includes knowledge graphs, maintenance records, and‘ OT skills,’ Hitachi’ s unique equipment failure cause analysis process based on STAMP and others. This achieves failure diagnostics that is on par with or exceeds the capabilities of Daikin’ s standard maintenance technicians. A preliminary demonstration test confirmed that the‘ Al Agent for Equipment Failure Diagnostics’ could identify the cause of equipment failure and recommend corrective actions within 10 seconds at an accuracy of over 90 %.
Daikin and Hitachi plan to complete the trial operation by September 2025 before beginning practical application of the Al agent. By developing it to Daikin’ s manufacturing bases both in Japan and overseas, the company intends to share its tacit knowledge of equipment maintenance as organisational knowledge in order to ensure global quality, the transfer of skills and improved productivity of frontline workers.
For its part, Hitachi will adopt the‘ Al Agent for Equipment Failure Diagnostics’ as a Lumada solution throughout the manufacturing industry and provide applications combining OT knowledge and IT into fields other than equipment maintenance. Hitachi will also help frontline workers improve work efficiency by including services such as the‘ Al Agent Development, Operation, and Environment Provision Service,’ which rapidly develops and generates Al agents that utiliSe OT knowledge.
Trimble expands field-to-office connectivity for heavy civil contractors production quantities achieved to planned quantities more easily and accurately. Continuous assessment of field progress can be critical for civil contractors, enabling them to make timely operational adjustments to protect profitability and to bill for accurate payments as work increments are completed.
T rimble has announced a new integration between its B2W Track and Trimble Siteworks software systems to automate and enhance progress quantity tracking for earthwork and civil contractors. This unique field-to-office connection allows contractors to compare actual material
“ Civil contractors must continuously evaluate how well projects are progressing against budgets, timelines and productivity goals,” said John Sheedy, Director Of Product Management at Trimble.“ Relying on phone calls, forms, emails and other disconnected communications tools to report on production quantities limits timeliness and accuracy of that reporting. This new software integration brings automation to the process to increase efficiency, eliminate errors and provide an auditable progress trail for billable milestones.”
