Description
Summary:Failure mode and effect analysis is a safety and reliability analysis tool that allows the identification of failures that could happen on a system and gives their effects and consequences. FMEA has many advantages, it is simple to use, time saving and highly effective. However. It has certainly some weaknesses. According to specialists, to obtain an effective result, FMEA needs the availability of all information and data. For new systems, a correct risk analysis cannot be performed. The use of only 3 factors cannot describe and judge correctly failures in all activities. In this article, we will propose a modification to the conventional FMEA. We propose the use of the TRIZ Anticipatory Failure Determination (AFD) to identify all possible failures of the system. The Analytic Hierarchy Process (AHP) is used to calculate the weight of each factor. Those weight will be introduced on the Risk Priority Number (RPN) calculation. To prove its efficiency, this approach will be applied on a product on development phase.
