Abstract

In this paper, several prior information fusion methods are considered comprehensively. Based on the failure distribution research, the environmental factor fusion method is more appropriate for the failure data of numerical control system. Outliers are deleted by using professional knowledge. By likelihood ratio test, we know that the shape parameters of the three groups of data are equal and the environmental factor is used to convert the historical data.
