ABSTRACT: Fuzzy FMEA provides a tool that can work in a better way with vague concepts and without sufficient information but it is necessary to look for the suitable membership function to the study case. To evaluate the revised matrix FMEA and fuzzy considerations, we present its application on a Discontinuous Distillation Plant of biofuel. First, it is shown the matrix obtained from the ordinary method with severity ranking and failure modes corresponding to the failure effects. Then, it is presented an FMEA in matrix form and finally both of them are presented with fuzzy technique applied. The most important conclusions as a result of the fuzzy techniques are shown and the most important result of the FMEA in a Discontinuous Distillation Plan of biofuel is presented.
