Application of Fuzzy Inference Techniques to FMEA

2006
In traditional Failure Mode and Effect Analysis (FMEA), the Risk Priority Number (RPN) ranking system is used to evaluate the risk level of failures, to rank failures, and to prioritize actions. This approach is simple but it suffers from several weaknesses.

A New Ranking Method For Fuzzy FMEA

2004
In this paper, we extend the method introduced by Bowles and Pelaez (1995) for the risk ranking in Failure Mode and Effect Analysis (FMEA). This method called as multi-ranking method allows combination of both the quantitative method (numeric ranking and fuzzy number) and the qualitative method (linguistic ranking) to be employed in the ranking of risk.

Using fuzzy FMEA and fuzzy logic in project risk management

2015
Risk management is one of the most important phases of project management and isthe most recently used by many researchers. In this paper, a fuzzy based method wasproposed which identifies different kinds of risks through the project life cycle.Then, the project risk magnitude can be obtained in regards to five factors, namely“severity”, “occurrence ...

A fuzzy data envelopment analysis approach for FMEA

Progress in Nuclear Energy, 2005
We present a data envelopment analysis approach for determining ranking indices among failure modes in which the typical FMEA parameters are modeled as fuzzy sets. By this approach, inference rules of the IF THEN kind can be bypassed. The proposed approach is applied to a typical PWR auxiliary feedwater system.

FMEA Using Fuzzy MULTIMOORA Method

2016
The MULTIMOORA method (Brauers and Zavadskas 2010) is a recently introduced MCDM method based on the multi-objective optimization by ratio analysis (MOORA) (Brauers and Zavadskas 2006). Due to its characteristics and capabilities, the use of MULTIMOORA method has been increasing in the literature. In Liu et al.

FUZZY ASSESSMENT OF FMEA FOR A SEWAGE PLANT

Journal of the Chinese Institute of Industrial Engineers, 2007
Failure mode and effect analysis (FMEA) is a widely used risk assessment tool to identify the potential failure modes of a product or a process. By ranking the priorities for corrective action according to the respective effects of the failures, the chance of the failures can be reduced or eliminated. However, there could be several difficulties during

Enhanced FMEA: An integrative approach of fuzzy logic-based FMEA and collective process capability analysis

Journal of the Operational Research Society, 2019
The aim of this study is to modify and enhance the quantitative/mathematical features of both computational and analytical aspects of the process failure modes and effects analysis (FMEA).

A Reliability Risk Assessment Method Based on Fuzzy FMEA

Applied Mechanics and Materials, 2011
A reliability risk assessment model based on fuzzy FMEA was presented by using fuzzy comprehensive evaluation. Fuzzy matrixes were constructed according to the investigation data, in which occurrence probability ranking, effect severity ranking and detection difficulty ranking are all weighted analyzed.
