ABSTRACT
For reparable systems, several mathematical models have been developed in the literature for optimal design of maintenance policies (for a survey, see for example (Cho and Parlar 1991; Dekker 1996)). Nevertheless, most of these models do not take into account the limitations on the resources required to perform maintenance actions. This drawback hasmotivated the development of a relatively new concept called the selective maintenance. The objective of the selective maintenance consists in finding, among all available maintenance actions, the set of appropriate actions to be performed, under some operation constraints, so that to maximize the system reliability or either to minimize the total maintenance cost or the total maintenance time. Selective maintenance, as a maintenance policy, is relevant to systems that are required to operate a sequence of missions such that, at the end of a mission, the system is put down for a finite length of time to provide an opportunity for equipment maintenance. Such systems may include for example manufacturing systems, computer systems and transportation systems.
