The effect of model uncertainty on maintenance optimization

  title={The effect of model uncertainty on maintenance optimization},
  author={Cornel Bunea and Tim Bedford},
  journal={IEEE Trans. Reliability},
Much operational reliability data available, e.g., in the nuclear industry, is heavily right-censored by preventive maintenance. The common methods for dealing with right-censored data (Total Time on Test statistic, Kaplan–Meier estimator, adjusted rank methods) assume the-independent competing-risk model for the underlying failure process and the censoring process, even though there are many -dependent competing-risk models that can also interpret the data. It is not possible to identify the… CONTINUE READING
