ABSTRACT: After a component change occurs, the enterprise needs to promptly update the configuration along the determined change path and quickly provide feedback on the configuration update plan for the complex product. Based on the design experience of designers, this paper analyzes the component configuration update and provides research ideas on complex product configuration updates driven by change. Firstly, a new modular division method is applied to modularize the complex product. Then, designers’ experience is analyzed based on intuitionistic fuzzy numbers, and the weights of alternative indicators for each component are dynamically calculated. The most suitable configuration update plan for production factor-related indicators is determined based on the integrated grey relational method. Finally, the feasibility and effectiveness of the research method proposed are verified by taking the component configuration update of a large capacity full DC high-speed permanent magnet synchronous variable frequency centrifugal unit as an example.
