The influence of imperfect maintenance on the Wiener process as a degradation model
1 : Otto-von-Guericke University Magdeburg
We consider a Wiener process with (possible nonlinear) drift for degradation modeling. Regularly, inspections are carried out,
and the level of degradation is measured. At each inspection point, a decision about preventive maintenance actions (replace
the system by a new one, let it as it is, ore make an incomplete repair with some degree) is possible. In the talk, we consider
the influence of such maintenance actions to the further developement of the degradation process and the resulting lifetime
distribution. Our aim is to find optimal time points of inspection and optimal decisions about maintenance actions.
