| Abstract: | In the paper, a multi-stage degradation system is considered, in which the Copula function is introduced to describe the correlation between two performance characteristics and Wiener processes are adopted to describe the degradation process of each performance characteristic in each stage. Explicit expression of the system reliability is given, and a numerical simulation algorithm based on Monte Carlo simulation is proposed, which verifies the correctness of the analytical results. Finally, some numerical examples are given to show the effectiveness of the proposed model. |
