A Grey Prediction Model on Vibration Severity Development of a Pump
A Grey Prediction Model on Vibration Severity Development of a Pump
摘要
Abstract
The method to enhance the precision of a grey model GM ( 1, 1 ) for predicting the development of vibration severity of a pump is investigated. The rectifying procedures involve the strtcture and the parameters regarding GM( 1,1 ). A new model based on GM ( 1, 1 ), which is GM ( E, 1,1 ), is proposed. In GM(E, 1, 1), the distribution of relative errors ratios between the original series and predicting series obtained by the mean of GM( 1,1 ) are considered in special points to set up the threshold and adjusting coefficients to control the modified action and the rectified amount based on distribution of the original series.The case shows that GM(E, 1, 1 ) is good at predicting the vibration severity development of the pump.关键词
