Each unit is subject to gradual deterioration and is monitored by sequential non-periodic inspections. It can be maintained by good as new preventive or corrective replacements. Every inspection or replacement entails a set-up cost and a component-specific unit cost but if actions on the two components are combined, the set-up cost is charged only once. A parametric maintenance decision framework is proposed to coordinate inspection/replacement of the two components and minimize the long-run maintenance cost of the system. A stochastic model is developed on the basis of the semi-regenerative properties of the maintained system state and the associated cost model is used to assess and optimize the performance of the maintenance model. Numerical experiments emphasize the interest of a control of the operation groupings. %G English %L hal-02284119 %U https://utt.hal.science/hal-02284119 %~ UNIV-NANTES %~ CNRS %~ UNIV-TROYES %~ EC-NANTES %~ IRCCYN %~ UNAM %~ UTT %~ UTT-LIST3N %~ LM2S-UTT %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022 %~ NU-CENTRALE
