Integrating optimisation, priority setting, planning and combining of maintenance activities

In this paper we present an integration of optimisation, priority setting, planning and combining of maintenance activities. We use a framework which covers several optimisation models, like the block replacement, a minimal repair and an efficiency model, and develop a uniform analysis for all these models. From this analysis penalty functions are derived which can act as priority criterion functions. These penalty functions also serve as basic elements in a method to determine optimal combinations of activities and in maintenance planning. The framework further assists in setting up an elicitation procedure, in case deterioration modelling is based on expert judgement rather than on statistical analysis of data.
