In view of the difficulties of engineering change propagation in aerospace products, a new history-based propagation path predicting method is proposed. Important parameters are obtained using the concepts of entropy and mutual information. Then, a parameter-similarity algorithm is proposed from the aspect of semantics and change-effect. Furthermore, the regulation and method of change propagation predicting are analyzed based on Bayes rules. Finally, an experiment of managing an aerospace turbine disk is performed to validate our method and it shows its validity and merits.
