Abstract

In the risk priority number (RPN) analysis, each evaluation index weight is the same, and it is impossible to conduct risk ranking for the same RPN value. In view of the above issues, the data envelopment analysis (DEA) and the risk priority number analysis are combined to analyze the failure mode risks of clamping and releasing tools. This method can increase the distinction of RPN, objectively search the failure mode ranking method and determine the risk grades of various failure modes of clamping and releasing tools. Therefore, it is beneficial for the designer to preferentially handle the most dangerous failure mode and can provide a basis for realizing the reliability allocation of function parts and improving the reliability of clamping and releasing tools.

Key words： clamping and releasing tool; failure risk analysis; data envelopment analysis
