We develop a matrix algebra approach for optimizing condition-based maintenance with planning time gradually deteriorating, continuously monitored equipment. This avoids the calculation times of simulation and approximations more direct approaches. consider model in which after failure should be planned as well, resulting downtime, emergency repairs upon failure. Numerical examples are provided...

In general, a complex system is composed of different components that are usually subject to maintenance policy. We take into account systems containing under both preventive and corrective maintenance. Preventive considered as failure-based model, where full renewal realized after the occurrence every nth failure. It offers an imperfect each repair deteriorates component or lifetime, probabili...

Maintenance accounts for approximately 20% of the operational cost aircraft; a margin higher than associated with fuel, crew, navigation, and landing fees. A significant percentage maintenance is attributed to failures aircraft components systems. These are random provide database which can further be analyzed aid decision-making optimization. In this paper, stochastic mathematical models poten...

-This paper presents an overview of resource optimization approach for transmission system maintenance selection and scheduling. The approach is based on failure rate estimation and risk reduction calculation followed by resource optimization. It also presents probabilistic models developed for circuit breakers and power transformers. An effort is made to quantify the effect of maintenance usin...
