In the Earlier NKS-project RAK-1 (1994-1997), the sub-project RAK-1.4, “Maintenance
Strategies and Ageing’’ focused on development of methodologies and tools for improving
maintenance strategies. In the NKS/SOS-2 project (1998-2001), the maintenance related
Nordic co-operation is continued. For exchange of information and as background and for
discussions related to maintenance decisions in the NKS/SOS-2 project, a mini-seminar on
maintenance strategies with an emphasis on reliability centred maintenance (RCM)
approaches was arranged 14.10.1999. The report summarises the topics of the presentations
and discussions at the seminar. The transparencies presented at the mini-seminar are
enclosed in this report.
