APPLICATION OF GREY COMBINATORIAL MODEL TO PREDICT CORROSION RATE OF PIPE

Grey system theory and method of time series analysis were combined to create a grey combinatorial model.Box-Jenkins model was introduced to analyze random component.Grey combinatorial model was applied to predict the change trend of corrosion rate of pipe,and the performance of the model was proved to be better by an example.The model was compared with other methods,and a conclusion that the precision of the model is superior was got.
