While the failure of unit 2 is catastrophic and it destroys unit 1 and so the whole system. Imperfect maintenance by using virtual age method and system replacement are executed when the failure occurs to component 1 and the whole system respectively. Under both the non-renewable FRWand renewable FRW, from the manufacturers' point of view, the system expected total warranty costs are explored. %G English %L hal-03322377 %U https://utt.hal.science/hal-03322377 %~ CNRS %~ UNIV-TROYES %~ UTT %~ UTT-LIST3N %~ LM2S-UTT
