Abstract
There have been many studies of maintenance policies in reliability theory, so that we have to select better policies that are suitable for objective systems in actual fields, such as age replacement, periodic replacement, replacement first and last, replacement overtime, and standby or parallel system, appeared in research areas. This chapter compares systematically maintenance policies and shows how to select one from the point of cost theoretically. The expected cost rates of maintenance policies and optimal solutions to minimize them are given, and their optimal policies such as replacement time \(T^{*}\), number \(N^{*}\) of working cycle, and number \(K^{*}\) of failures are obtained. Furthermore, we discuss comparisons of optimal policies to show which is better analytical and numerically. These techniques and tools used in this chapter would be useful for reliability engineers who are worried about how to adopt better maintenance policies.
