This paper presents a special case of integration of the preventive maintenance into the repair/replacement policy of a failure-prone system. The machine of the considered system exhibits increasing failure intensity and increasing repair times. To reduce the failure rate and subsequent repair times following a failure, there is an incentive to perform preventive maintenance on the machine befo...

Software systems experience gradual performance degradation despite of which they are required to perform service, though at a degraded level. Different preventive and corrective techniques (restart, rejuvenation etc.) have been applied to restore efficient service of the system. In this paper, we model the process of degradation together with the corrective actions of minimal repair, major rep...

Typical control charts output a single signal called an alarm upon detection of an abrupt change. This alarm may serve a variety of functions depending on the context. Alarms for mechanical, chemical, or electrical systems often drive maintenance actions. The timing and nature of these maintenance actions may in turn have a significant impact on the long-term cost or profitability of the system...
