Life Estimation from Pooled Discrete Renewal Counts

  • Michael Tortorella


We study a problem arising in the analysis of field reliability data generated by a repair process that replaces at a depot individual components on line-replaceable units that then are returned to service. Data collected in such a repair scenario is usually limited to counts of the number of components replaced each month without regard to age. We construct a pooled discrete renewal process model for this scenario and study a maximum likelihood-like estimation of the parameters in this model
