Abstract:

Component DMC estimation is a vital procedure in maintenance cost control. Aiming at the disadvantages of existing estimation methods such as low accuracy and large fluctuation, a new method based on AdaBoost (adaptive boosting) is introduced. Experiments show that this method does not rely on empirical data, it is obviously more accurate and stable than former ones. It is applicable to estimate the component DMC during design and maintenance process.
