Such a model is useful in practice since a sudden change in environmental conditions may cause a larger shock. In particular, the reliability and mean time to failure of the system is obtained by assuming that the times between arrivals of shocks follow phase-type distribution. The optimal replacement policy that is based on a control limit is also proposed. The results are illustrated when the number of shocks until the change point follows geometric distribution.eninfo:eu-repo/semantics/closedAccessChange pointExtreme shock modelOptimal replacementPhase-type distributionReliabilityArticleQ1190WOS:000474497100015
