Abstract
O presente trabalho apresenta uma abordagem baseada em análise envoltória de dados (Data Envelopment Analysis - DEA) para estabelecer direcionamentos de melhoria para os modos de falhas identificados na análise dos modos e efeitos de falha (FMEA). A abordagem tradicional da FMEA baseia-se num número de priorização de riscos que vem sendo alvo de inúmeras críticas embasadas em diversos artigos científicos. No presente trabalho, o número de priorização de risco é baseado em DEA. Por meio desse número de priorização de risco DEA, considerando-se o conceito de fronteira de eficiência, serão identificadas diretrizes de melhoria para os modos de falha com base nos índices de risco estabelecidos pela equipe executora da FMEA. Por meio dos resultados alcançados nas duas aplicações práticas, pode-se demonstrar a eficácia da abordagem proposta para tratar essa classe de problemas.
The present study presents a data envelopment analysis (DEA) based approach to establish guidelines for the improvement of the failure modes identified by a failure mode and effect analysis (FMEA). The traditional FMEA approach is based on risk priority number (RPN), which has been target of scientific criticism. In the present study, the RPN is based on DEA and considers the concept of efficiency frontier. Based on this concept and on the risk indexes, some improvement directives for the failure modes can be established. The obtained results concerning the two practical applications demonstrate the effectiveness of the proposed approach in dealing with this kind of problem.
