Energy production of a power plant is significantly affected by the availability of spare parts for machinery operation and maintenance (O&M). The availability of spare parts prevents prolonged breakdown and maintenance. However, even though some quantitative methods exist to determine the number of spare parts, to avoid the events occurring, generally …

Darko et al. [4] explored the model for the determination of the spare part ordering decision when the component in operation is subject to a condition monitoring programme. The decision to order depends on the remaining useful life (RUL) calculation obtained through (i) the component age assessment and (ii) condition indicators (covariates) that are representative of …
