Ultrasonic Flowmeter Life Analysis of the Grey Prediction

摘要：

To address the issue that the traditional prediction methods can not predict and estimate when facing small sample data or nonlinearity and stochastic data,a gray forecasting model in allusion to small sample and poor information is proposed.The model is optimized by second-order weakening operator and its accuracy is tested by four methods.On the basis of Monte-Carlo emulation result,lifetime is calculated through the observation method with forecast data.This method has a good operability and modeling can be programmed on computer.Finally,the feasibility of the method is verified by theoretical analysis and mathematical calculation.
