Estimation of limiting availability for a stationary bivariate process

  • B. Abraham (a1) and N. Balakrishna (a1)


We estimate the limiting availability of a system when the operating and repair times form a stationary bivariate sequence. These estimators are shown to be consistent and asymptotically normal under certain conditions. In particular, we estimate the limiting availability for a bivariate exponential autoregressive process.
