Dynamic Preventive Maintenance, Optimization of Time between Overhaul

We present in this paper an method for evaluating the reliability in real time applied to the optimization of preventive maintenance and evaluation of the parameters of dependability. This approach is based on a function Z (t), which assesses the damage from the history of real operating conditions. This assessment is used to calculate the residual reliability, and can then be used to optimize the preventive maintenance and in particular optimize the time between overhaul (TBO). This approach can be used to take more realistic decisions about preventive change and thus led to a better risk management.
