Abstract
If a component in a binary system fails, preventive maintenance (PM) on other components may be conducted while the failed component is being repaired. This raises a question on which components should be selected for PM if maintenance resource is limited. The question can be answered by using the component maintenance priority (CMP) to prioritise components for PM. This paper extends the definition of the CMP to the cases of multi-state systems, continuum systems and non-coherent systems, respectively. It investigates the applications of the proposed measures for multi-state systems in optimisation of maintenance policies and proposes algorithms to minimise maintenance cost. A case study is used to instantiate the validity of the proposed measures.
