Failure mode and effect analysis (FMEA) is one of the formal techniques for evaluation of failure mode in mechanical and electronic equipments. The FMEA may be a very helpful tool for identifying weak points in the design stage of a product/process. The aim of this paper is to develop a new maintenance decision strategy by integrating the criticality of various factors related to failure and repair of a component/subsystem as an alternative to traditional approach of Failure Mode and Effect Analysis (FMEA). The methodology presented is based on Analytical Network Process (ANP), a multicriteria decision making technique. We propose a decision support tool analysis for determining maintenance priority action in which the typical FMEA parameters are modeled.

Abstract
Failure mode and effect analysis (FMEA) is one of the formal techniques for evaluation of failure mode in mechanical and electronic equipments. The FMEA may be a very helpful tool for identifying weak points in the design stage of a product/process. The aim of this paper is to develop a new maintenance decision strategy by integrating the criticality of various factors related to failure and repair of a component/subsystem as an alternative to traditional approach of Failure Mode and Effect Analysis (FMEA). The methodology presented is based on Analytical Network Process (ANP), a multicriteria decision making technique. We propose a decision support tool analysis for determining maintenance priority action in which the typical FMEA parameters are modeled. The approach has been validated in a real case study concerning the European Train Control System - E.T.C.S.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
