FMEA Using HTL-QUALIFLEX Approach and Its Application to C-Arm X-Ray Machine
In this chapter, we aim to develop a new risk priority method for FMEA by integrating hesitant 2-tuple linguistic term sets and an extended qualitative flexible multiple criteria method (QUALIFLEX) approach. The concept of hesitant 2-tuple linguistic term sets is first presented to express various uncertainties in the assessment information of FMEA team members. Borrowing the idea of gray relational analysis (GRA), a multiple objective optimization model is constructed to determine the relative weights of risk factors with incomplete weight information. The extended QUALIFLEX approach with an inclusion comparison method is then suggested to determine the risk ranking of failure modes. Finally, the practicality and effectiveness of the proposed FMEA are demonstrated through a case study of C-arm X-ray machine, and the results show that the new risk priority approach is useful and flexible for handling complicated FMEA problems and can yield a reasonable and credible priority ranking of failure modes.
