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,

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 ...

Definition and Analysis of a New Risk Priority Number Concept

2004
Risk 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).

Risk Analysis of Propulsion System based on Similarity Measure and Weighted Fuzzy Risk Priority Number in FMEA

International Journal of Turbo & Jet-Engines, 2018
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.

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.
