The Risk Priority Number methodology for distribution priority of emergency logistics after earthquake disasters

MSIE 2011, 2011
Efficient distribution for emergency logistics is vital to alleviate the disaster impact after the occurrence of earthquake. This paper studies the distribution priority of different rescue resource. Using Risk Priority Number (RPN) methodology,a dynamic model for identifying the relief-demand urgency is built.

An improved cost-based method of Risk Priority Number

Proceedings of the IEEE 2012 Prognostics and System Health Management Conference (PHM-2012 Beijing), 2012
Process failure mode effect and critically analysis (PFMECA) is one of the most popular methods to study the reliability of process system. The method of Risk Priority Number (RPN) is the key part of PFMECA. Many experts have studied it in a long period of time. But the method has some drawbacks, such like sensitivity to small changes.

An improved risk priority number method based on AHP

2013 Proceedings Annual Reliability and Maintainability Symposium (RAMS), 2013
Process failure mode effect and critically analysis (PFMECA) is a widely used method to study the reliability of the manufacturing system. The method of Risk Priority Number (RPN) is the key part of PFMECA. It is used to determine the risk degree of each process failure mode. However, the traditional RPN method of PFMECA has some drawbacks.

Automation of risk priority number calculation of photovoltaic modules

2016 IEEE 43rd Photovoltaic Specialists Conference (PVSC), 2016
Statistical risk analysis on the field observed defects/failures in the photovoltaic (PV) power plants is usually carried out using a combination of several manual methods which are often laborious, time consuming and prone to human errors. In order to mitigate these issues, an automated statistical risk analysis based on FMECA (failure mode effect ...

ANP/RPN: a multi criteria evaluation of the Risk Priority Number

Quality and Reliability Engineering International, 2011
AbstractThis paper presents an advanced version of the failure mode effects and criticality analysis (FMECA), whose capabilities are enhanced; in that the criticality assessment takes into account possible interactions among the principal causes of failure.

VIKOR power law-based customer-oriented FMEA with complete unique risk priority numbers

International Journal of Quality & Reliability Management, 2021
PurposeAn inherent problem on risk priority number (RPN) value duplication of traditional failure modes and effect analysis (FMEA) also exists in two customer-oriented FMEAs. One has no unique value, and another has 1% unique values out of 4,000 possible values.

Fuzzy-based risk priority number in FMEA for semiconductor wafer processes

International Journal of Production Research, 2013
Semiconductor wafer manufacturing processes are considered to be complex and require considerable manpower and financial investment. Effective control to promote wafer yield is thus a very important issue. Many computational problems in traditional failure mode approaches, such as variable selection and data collection, are far too dependent on the ...

Fuzzy-Based Approach to Solve Classical Risk Priority Number Drawbacks for Railway Signaling Systems

IEEE Intelligent Transportation Systems Magazine, 2023
Failure modes, effects, and criticality analysis (FMECA) is a powerful tool used to quantify the risk related to safety-critical systems and to develop the proper corrective actions to minimize the associated risk. However, traditional FMECA has been widely criticized for its many drawbacks and weaknesses. Different combinations of occurrence, severity,
