According to renewal process theory, a random inspection model subject to external shock was established, and the availability and the long-run average cost per unit time were investigated. Assuming that the intervals between inspection times formed a Poisson process, the optimal inspection policy of the model was obtained by mining the long-run average cost per unit time. The results have shown that the random inspection model is superior to the existing model for the system subject to external shocks. Furthermore, the function of the system was discussed by introducing the random idea, and i...
