An improved risk priority number method based on AHP
2013 Proceedings Annual Reliability and Maintainability Symposium (RAMS), 2013Process 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), 2016Statistical 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 ...

An improved cost-based method of Risk Priority Number
Proceedings of the IEEE 2012 Prognostics and System Health Management Conference (PHM-2012 Beijing), 2012Process 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.

General model for the risk priority number in failure mode and effects analysis
Reliability Engineering & System Safety, 2018Abstract Failure mode and effects analysis (FMEA) is a structured method used during a given stage of the system life cycle to understand all probable failure modes and the effects of their occurrences. The risk priority number (RPN) is calculated in FMEA to select more critical failure modes by multiplying three factors: occurrence, detection, and ...

Risk priority number for PV module defects: influence of climatic condition
New Concepts in Solar and Thermal Radiation Conversion and Reliability, 2018Over the course of their lifetime, photovoltaic (PV) modules develop defects and experience performance degradation due to local environmental stresses. The defect type and rate of degradation depend upon cell technology, module construction type, module manufacturing quality control, installer workmanship, and the installed environment. Defects can be
