“…We note that this approach does not take into account that the time horizon is finite. However, it is used because determining optimal maintenance strategies for finite time horizons, which is not the essence of our study, is complex [10,21,30,36]. Furthermore, the error of minimizing the cost rate is acceptable if the length S of the time horizon is large compared to the mean time until a breakdown [29].…”

We consider the problem of scheduling time-based preventive maintenance under uncertainty in the lifetime distribution of a unit, with the understanding that every time a maintenance action is carried out, additional information on the lifetime distribution becomes available. Under such circumstances, typically either point estimates for the unknown parameters are used, or expected costs are minimized taking the uncertainty in the parameters into account. Both approaches, however, ignore that the uncertainty is reduced much faster if preventive maintenance actions are postponed. Although this initially leads to higher costs due to a higher risk of breakdowns, the obtained additional information can be exploited thereafter as it enables better maintenance decisions going forward. We assess the longterm benefits of initially postponing preventive maintenance, and perform a numerical study to identify under what circumstances these benefits are largest. This study is the first to recognize that the choice of a maintenance strategy influences the information that becomes available, and aims to initiate follow-up research in the area of maintenance planning.

In this article a number of maintenance models for finite horizons are reviewed. These methods have not been applied as frequently as their infinite horizon counterparts, and yet are very much applicable to systems under maintenance and repair contracts. The emphasis in this paper is on repairable systems under maintenance and repair contracts, where the decision has to be made whether and when to repair or replace the system. Based on a case study, a new finite horizon model will be constructed and new approaches to analyze and improve repair/replacement decisions under a finite horizon introduced. Finally, the meaning of 'risk' and 'criticality' in the context of maintenance contracts will be discussed and quantified.

“…In this paper, we consider a system with a critical component that fails randomly and requires maintenance during the lifespan of the system. Motivated by the fact that capital goods often have a planned duration of service at the time of acquisition ( Cheng, Pandey, & van der Weide, 2012;Jiang, 2009;Lugtigheid, Jiang, & Jardine, 2008;Nakagawa & Mizutani, 2009 ), we assume that the system lifespan is finite and known. We assume that age-based maintenance is applied to preventively replace the critical component.…”
