Abstract: Abstract In this chapter, we begin with the study of repairable systems. Specifically, we study probabilistic models for systems which after failure are replaced by a new one exactly. We say then that the system operating state is restored to “as good as new” conditions after failure. In the first approach to this kind of systems, we assume that the system is repaired (replaced) and put into new operation immediately after the failure. The sample information that we analyze consist of a sequence of random variables independent and identically distributed, which represent the time between two consecutive failures. The model that we consider in this situation is a Renewal Process, and the main purpose is to present and compare several ways of nonparametrically estimate the renewal function, that is, the expected number of failures occurring in the system up to a given time t. When the repair times are of interest, the data collected consist of a sequence of alternating up and down periods. The modeling tool indicated in this case is the Alternating Renewal Process, and we will concentrate on estimating the availability function (the probability that the system is functioning at a given time) using nonparametric techniques.
