Abstract
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. (2014), the authors proposed a new risk priority model by applying fuzzy set theory and MULTIMOORA method for failure modes assessment and ranking in FMEA. The risk factors and their relative weights are treated as fuzzy variables and evaluated by using fuzzy linguistic terms and fuzzy ratings. An extended MULTIMOORA method is used to determine the risk ranking of the failure modes that have been identified. The new risk priority model can be a useful tool for determining the ranking orders of the identified failure modes in FMEA and taking preventive actions for safety and reliability improvement.
