| Abstract: | The gray model and Weibull distribution were combined to established a Gray-Weibull Model,then they were employed to predict failure rate of chemical equipments.Calculating and analyzing some cases show that the prediction result matches well with the practical situation;having the gray model and unary linear regression model compared in equipment life prediction shows that gray model performs better. |
| Keywords: | chemical machinery gray prediction unary linear regression model combined model loss prediction |
