... and constructs a correlation network model of these parts based on complex network theory. By comprehensively considering the influence of part nodes and their association relationships within the complex network, the intensity of change propagation is calculated using node importance and the probability...

...; published online June 2, 2014. Assoc. Editor: Irem Y. Tumer. 09 09 2013 29 03 2014 A simulation model to help manage change propagation through design workflows is introduced. The model predicts resource requirements and schedule risk of a change process, accounting for concurrency...

... and cause further knock-on changes. Such change propagation causes uncertainty in design time, cost, and quality and thus needs to be predicted and controlled. Current engineering change propagation models map the product connectivity into a single-domain network and model change propagation as spread...
