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

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.

FMEA Using Fuzzy Digraph and Matrix Approach

2016
The digraph and matrix approach (Rao and Gandhi 2002; Baykasoglu 2014) is based on graph theory and matrix algebra and has some desirable properties, such as “ability to model criteria interactions” and “ability to generate hierarchical models,” for solving complex decision-making problems.

FMEA Using Intuitionistic Fuzzy Hybrid TOPSIS Approach

2016
In Chap. 3, the theory of intuitionistic fuzzy sets (IFSs) has been proven to be useful for FMEA to deal with the vagueness and uncertainty existed in the risk-evaluating process. The technique for order preference by similarity to ideal solution (TOPSIS), proposed by Hwang and Yoon (1981), is one of the well-known MCDM methods and has been extensively
