Abstract: A software safety analysis method based on the component-level failure modeling is proposed. By using the extended Failure Propagation and Transformation Notation(FPTN), the failure behaviors of all components are described. It performs the architectural safety analysis by considering the architectural characteristics of various software system components. The safety level can be determined using the correlative fuzzy method. Combining with the example, the failure propagation probability can be obtained, and the results prove the effectiveness of the method.
