Methodologies of Reliability Engineering are advancing, and one of the central methods is the identification of failure. The failure analysis is handled based on Failure Physics with Data Science.
However, the failure issues are complex, and the aim of the engineering method is to improve the reliability. In particular, the reliability design is necessary according to the failure mechanism identified on the method.
Indeed, the preventive handling for defect is significant. Then, the method is constructed based on predictions of failures. This is extremely difficult.
