ABSTRACT
This paper proposes a new quantitative reliability analysis method for repairable systems with multiple correlations based on Goal Oriented (GO) method. First, the solving methods for repairable systems with shutdown correlation, maintenance correlation, standby correlation and common cause failure in GO method are presented. And the reliability analysis process of this paper’s GO method is formulated. Then, the hydraulic oil supply system of heavy vehicle is taken as an example to conduct reliability analysis by this paper’s GO method. Finally, in order to verify the feasibility and advantage of the proposed GO method, its analysis result compared with those by GO method for system without considering correlations and system with considering a single kind correlation. All in all, this study not only improves the theory GO methodology; but also provides a new reliability analysis approach for repairable systems with multiple correlations.
