Complex technical systems, over their design life, are subject to preventive maintenance. Viewed as a field service activity, preventive maintenance is necessary to meet a system's reliability and availability (readiness) requirements. The question is what should be the optimal schedule of such preventive maintenance actions? Optimal in the sense that high frequency of these actions increases the cost of maintaining the system's operation but reduces the cost due to the system's downtime, while low frequency – decreases the cost system's operation but increases the cost of downtime. This presentation reviews mathematical (statistical) models that are used for preventive maintenance optimization and illustrated by case studies from the Vasiliy’s corporate experience.
