Design FMEA for a diesel engine using two risk priority numbers
2012 Proceedings Annual Reliability and Maintainability Symposium, 2012Failure Modes and Effects Analysis (FMEA) is an effective technique for identifying and eliminating possible failures. FMEA has been widely used in the manufacturing industry and in various phases of the life cycle of a product. The aim of FMEA is to ensure high quality and reliability.

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

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 ...

AbstractDue to the epistemic uncertainty, it is difficult for the experts to give precise parameter values in Risk Priority Number (RPN) evaluations. To overcome this drawback, a hybrid method is proposed by integrating the concepts of fuzzy set theory, weight analysis and similarity value measure of fuzzy numbers.

PRIORITIZING THE RISK PRIORITY NUMBERS IN FMECA – A HEURISTIC APPROACH
Risk management is one of the most important fields that diagnose hazards and traces by the application of various tools available. In any mines or industries it is necessary to estimate and predict the risk associated with the components/equipment or machineries in order to avoid the loss/damage.Dr. M. Pradeep Kumar +2 more

Definition and Analysis of a New Risk Priority Number Concept
2004Risk Priority Numbers (RPNs) are a powerful qualitative method for discovering and prioritising critical issues in early design phases. They have become very popular in particular as a tool in automotive or software Failure Modes, Effects, and Criticality Analysis (FMECA).

Study of a new Analysis Method of Risk Priority Number Based on FMEA
SAE Technical Paper Series, 2015<div class="section abstract"><div class="htmlview paragraph">In order to overcome the drawback that the traditional risk priority number method could not clearly make a risk priority sequence, a new analysis method of RPN was presented. Combined with loss costs, this method was based on FMEA.
