A Reliability Risk Assessment Method Based on Fuzzy FMEA
A reliability risk assessment model based on fuzzy FMEA was presented by using fuzzy comprehensive evaluation. Fuzzy matrixes were constructed according to the investigation data, in which occurrence probability ranking, effect severity ranking and detection difficulty ranking are all weighted analyzed. A fuzzy hierarchy analysis method was used to obtain the weight of each influence factor. In the model, the potential fault modes and the reasons can be analyzed and the preventive measures can be taken in prevention stage to avoid finding the problems after the products are put into production and market. It will provide new ideas and new methods to improve the operation security of the engine, to prevent and forecast failure, and to estimate and control the risk.
