Reliability prediction method based on priority of available information quality

摘要

A method for predicting reliability based on priority of available information quality is disclosed. In this method, it is first judged whether field data, similar part data, or test data for a part subject to reliability prediction exist. Thereafter, reliability prediction for the target part is performed using field data for the target part, similar part data, or data that exists if there is test data. However, when field data, similar part data, or test data for the target part do not exist, the reliability prediction for the target part is performed using a predefined specification for reliability prediction. At this time, the step in which the reliability prediction for the target part is performed using the predefined specification sheet is based on the priority of the available information quality including the type of the target part and the use environment condition. Reliability prediction is performed for
