By learning the decision-making criteria used by experts in product design, this solution enables AI to determine whether design drawings comply with established rules. The company explained that because errors can be detected at an early stage of design, the solution contributes to reducing rework caused by design changes and maintaining or improving design quality.
Additionally, to support data utilization in the design process, the solution includes features to organize information such as design history, enabling smooth handover to subsequent processes. Hitachi stated that it will deploy this technology as a foundation for improving efficiency in design operations within the manufacturing industry.
