•A Wiener process with random drift is used to model the heterogeneous degradation.•A cost model is developed based on real-time RUL distribution and one-cycle criteria.•The failure rate is proven to be non-monotonic, first increasing and then decreasing.•The optimal PR interval is derived analytica...
