Proposta de uma nova abordagem da ferramenta FMEA para o desenvolvimento de novos produtos

Abstract

In an increasingly efficient market, optimizing the tools that reduce the search and the final costs of the product or process is an essential point for competitiveness. In this scenario, the FMEA (Failure Mode and Effect Analysis) tool is widely used in the analysis of the failure mode and effect, but it presents all the risks through the quantification of the RPN (Risk Priority Number). In this way, this work sought an adaptation of the RPN evaluation criterion in the FMEA, based on decision-making aid methods, using the Direct Rating for variables and the Fuzzy-TOPSIS method for decision making. The method was applied to the project of transportable carbonization furnaces of Biscaia (2021), seeking an assessment of the feasibility of the optimized method. It is possible to visualize the auxiliary method in the distribution of the existing uncertainties and not to point out the greatest importance for the realization of the project. The inclusion of new criteria for considering expansion criteria in relation to maintenance and criteria, before criteria for considering traditional criteria. The proposed method was eliminated among the RPN values, combining an analysis between the critical failure modes and that require more urgent and relevant actions in the new product development stage.
