A novel optimal preventive maintenance policy for a cold standby system based on semi-Markov theory
A novel optimal preventive maintenance policy for a cold standby system based on semi-Markov theory is described. The issue studied in this paper comes from the practical flattener control system in a steel plant. Optimal preventive maintenance cycle corresponding to the maximum of mean time to system failure is derived. All the maximums of MTSF obtained are higher than the scheme of Mahmoud and Moshref (2010). The optimal results obtained have been applied to the PM policy of the flattener control system.
