Abstract

This paper develops a model of a condition-based maintenance policy for a two-component
system with both stochastic and economic dependencies. The stochastic dependency is such
that the degradation rate of each component depends not only on its own state (degradation
level) but also on the state of the other component. The economic dependency is such
that combining multiple maintenance activities has lower cost than performing maintenance on
components separately. To select a component or components to be preventively maintained,
adaptive preventive maintenance and opportunistic maintenance rules are proposed. A cost
model is developed to find the optimal values of decision variables. A case study of a gearbox
system demonstrates the utility of the proposed model.
Keywords: Condition-based maintenance, maintenance optimization, two-component system,
state dependence, stochastic dependence, economic dependence.
