Methodology of integrated knowledge management in lifecycle of product development process and its implementation

This paper first provides a literature review of product development and knowledge management including product development process, design history and domain knowledge. It then presents a method for knowledge-based multi-view process modeling including process implementation, process monitoring, and knowledge management. The integrated framework and hierarchical model of the design history is built. The relationship among process history, design intent and domain knowledge is analyzed, and the method for representation and acquisition of process history, design intent and domain knowledge is presented. The multi-agent based architecture of the knowledge-based product development process management (PDPM) system and its functional modules are described, and the architecture of integrated knowledge management (IKM) system based on PDPM is set up and developed with a B/C/S (Browser/Client/Server) structure. The system is used successfully during the lifecycle of a new type of railway rolling stock development.
