For the problem that it is difficult to determine the type of failure occurring in machining centers, Minitab software is used to process and analyze the failure data, and the type of failure distribution is found to obey the Weibull distribution. Based on the CCR model in the data envelope method, the reliability index is applied to allocate the reliability of the machining center, and according to the practical applicability of the allocation method, the redistribution problem of reliability is better improved, and the reliability level of the whole machine is improved.
