针对某型发动机滑油颗粒监测试验数据预测分析的需要,主要研究了时间序列模型和灰色模型两种预测模型,并有机结合起来,形成新的灰色时序模型;分别进行预测分析,并比较预测精度。预测结果表明:灰色时序模型预测精度高,具有很好的预测能力,有较高的实用意义。
Aiming at the need of predicting and analyzing the test data of a certain type of engine oil particle, the paper mainly studies two forecasting models of time series model and gray model and combines them organically to form a new gray time series model. Predict and analyze respectively, and compare the prediction accuracy . The prediction results show that the gray time series model has high prediction accuracy and good predictive ability, which is of high practical significance.
