Abstract
The main objective of this paper is to propose a new method for failure mode and effects analysis
(FMEA) based on Z-numbers. In the proposed method, firstly, Z-numbers are used to perform the
valuations (Z-valuation) of the risk factors like occurrence (O), severity (S) and detection (D). Secondly,
the Z-valuations of the risk factors are integrated by fuzzy weighted mean method. A new risk priority
number named as ZRPN is calculated to prioritize failure modes based on a modified method of
ranking fuzzy numbers. Finally, a case study for the rotor blades of an aircraft turbine is performed to
demonstrate the feasibility of the proposed method.
