Research on complex product design change propagation based on complex networks

How to accurately evaluate the impact of design change during the whole design, and make decisions on the change request is the most important problem facing the complex product design changes. By means of studying the change rule of node state and the mechanism of change propagation in complex product design network, the improved cuckoo search algorithm is used to solve the design change propagation path, which lays a foundation for comprehensive and accurate evaluation of the influence of change on complex product design.
