Evolution of corrosion of civil aircraft based on improved grey models
Structure corrosion is one of the most common damages affecting the structural integrity of the aging civil aircraft. Three grey models were applied for predicting the corrosion evolution during aircraft maintenance checks. The developed models include the basic GM (1, 1) model and two improved mod...
