A system which is either working or under repair is modeled as an alternating renewal
process. Data is in the form of a finite number of independent lifetimes and repair
times. Several semi-parametric estimators of the probability that the system is up at a
finite time t are studied via simulation. The estimators are based on an exponential approximation
to the true system availability at time t and use empirical Laplace transforms
of the lifetimes and repair times.
