Abstract: Digital Knowledge Management Model Empowering Intelligent Manufacturing in Enterprises Chongkai Zhong, Lingyu Sun, Jinhao Zhang*, Jiayao Li (Planning and Strategy Division, China Academy of Industrial Internet, Beijing 100102, China) Intelligent manufacturing is an essential pathway to drive high-quality development in manufacturing enterprises, while knowledge management serves as a critical enabler for its implementation. Business decision models based on knowledge can further enhance the intelligent capabilities of manufacturing enterprises. This study establishes a framework for enterprise knowledge management, systematically organizes knowledge directories, assigns unified tags to knowledge assets, standardizes knowledge management processes, and constructs a unified knowledge repository. By leveraging knowledge graph technology, a systematic knowledge management model integrating business and technical domains is developed. This model standardizes the entire lifecycle of knowledge management - from identification to application - and provides actionable guidance for the design and implementation of knowledge management systems. The proposed approach facilitates knowledge servitization and promotes intelligent business.
