DX AI is presented as a solution for smart manufacturing, integrating AI to revolutionize quality, equipment, and safety management. It addresses challenges like fragmented data, lack of connected analysis, and loss of expert knowledge in manufacturing environments. The proposed system uses domain-specific AI agents and ontology-based RAG technology to centralize data, predict risks, and provide real-time support to workers. Key features include RAG-powered chatbots, drawing analysis, and IoT monitoring, all designed for operation within secure, closed networks. Ultimately, DX AI aims to be a practical AI partner that understands manufacturing processes and offers tangible improvements in efficiency and safety, contrasting with more general, cloud-dependent solutions.
