Methodology of integrated knowledge management in lifecycle of product development process

This work 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 the 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 acquisition and management of process history, design intent and domain knowledge is presented. The functional modules of knowledge-based PDPM system are described, and the architecture of integrated knowledge management (IKM) system based on PDPM is set up and developed with a B/C/S structure. The system is used successfully during the life cycle of a new type of railway rolling stock development in a Chinese enterprise.
