Maintenance strategies
Maintenance is needed to ensure that the components
carry on the purposes for which they were designed.
The basic objectives of the maintenance activity are to
deploy the minimum resources required to make sure that
components perform their intended purposes properly, to
ensure system reliability and to recover from breakdowns
(Knezevic, 1993). As is shown in Figure 1, the overall
maintenance strategy consists of the supporting programs.
Broadly, the strategy consists of preventive and corrective
maintenance programs.
