【 摘 要 】

The gyro device is the key navigation component for maritime tracking and control, and gyro shift is the key factor which influences the performance of the gyro device, which makes conducting the reliability analysis on the gyro device very important. For the gyro device reliability analysis, the residual life probability prediction plays an essential role although it requires a complex process adapted by existed studies. In this study the Belief Rule Base (BRB) system is applied to model the relationship between the time as the input and the residual life probability as the output. Two scenarios are designed to study the robustness of the proposed BRB prediction model. The comparative results show that the BRB prediction model performs better in Scenario II when new the referenced values are predictable.
