N2 - For a single asset one can obtain the optimal maintenance strategy for a wide range of assumptions about deterioration, maintenance actions and costs. For example Ansell et al (2004) and Ansell and Archibald (2008) developed approaches based on data driven models which included repair, refurbishment and replacement in the presence of covariates. Archibald et al (2004) also explored the sensitivity of such solutions to parameter changes in the model. In practices, though, it may not be possible to implement the optimal solution. It may be necessary to keep the equipment working until maintenance facilities are available or there may be operational reasons to retain equipment in action. Ansell et al (2003) showed that it is possible to assess the impact of maintenance actions (replacement, refurbishment or repair). In this paper the impact of delay in refurbishment and replacement is considered. This is based on the assumptions of Cox and Lewis's NHPP model, though, it is possible to consider alternative deterioration models. Empirical results are presented with theoretical justification.
