Maintenance analysis of a two-component loadsharing system
Reliability Engineering and System Safe
This paper presents a two-component load-sharing system. The failure rates of the two components are time dependent and load dependent. Whenever one fails, it is imperfectly repaired with a time delay during which the failure rate of the survival component increases because of the resulting overload. Three maintenance policies are proposed considering imperfect preventive maintenance and system replacement. The optimal average costs in the long run under different maintenance policies are derived from the theoretical propositions. Both numerical results and Monte Carlo simulations are presented in the study. A sensitivity analysis of the maintenance policies is carried out.
