A Literature Review on Fuzzy FMEA and an Application on Infant Car Seat Design Using Spherical Fuzzy Sets

Abstract

Failure mode and effects analysis (FMEA) is a structured approach to determine the potential failures that may arise during the implementation of a process. Because of the vagueness and impreciseness in the definition of severity, occurrence probability, and detectability factors, fuzzy set-based techniques can be used in FMEA. Spherical fuzzy sets are a recently developed extension of ordinary fuzzy sets integrating the principles of neutrosophic sets and Pythagorean fuzzy sets. In this chapter, we summarize the literature on fuzzy FMEA and propose a spherical fuzzy FMEA model with an illustrative application on infant car seats design.
