“…A new switching strategy for standby components was proposed by Ardakan et al 28 In studies on active switching strategies, most scholars adopt periodic switching as the switching strategy between components. [29][30][31][32] The periodic switching policy can effectively reduce the probability of component failure. However, the periodic switching interval is determined mainly based on the engineer's experience, which can lead to insufficient accuracy.…”

This paper proposes a novel condition‐based maintenance model for a two‐component warm standby system considering an imperfect switching policy. Unlike the conventional models, joint optimization of preventive and failure switching strategies is investigated. The standby component can be switched preventively when the component reaches the preventive maintenance (PM) threshold before the online one fails. The failure switching is triggered when the online component reaches the corrective maintenance (CM) threshold. In addition, the switching mechanism between the two components is related to the order fulfillment rate. The optimal PM threshold and order fulfillment rate can be derived by minimizing the long‐term average cost rate. A numerical example is provided to demonstrate the robustness of the decision model under different scenarios through sensitivity analysis. Ultimately, the effectiveness of the proposed model in this article was verified by comparing the models.

This article investigates an optimal preventive standby activation policy for an m$$ m $$‐out‐of‐n$$ n $$ redundant system. We assume that for such a system, which starts operating at time t=0$$ t=0 $$, a standby component will be activated at either the failure time of the system or at a predetermined time τ$$ \tau $$, whichever occurs first. We first obtain the system reliability function under this switching policy as a function of τ$$ \tau $$. Then, we investigate the optimal switching time τ$$ \tau $$ so that the mean time to failure of the system is maximized. The results indicate that the existence of an optimal value of τ$$ \tau $$ depends on the lifetime of the standby redundancy and its virtual age in the standby state. Some illustrative examples are presented to examine the theoretical outcomes.
