This paper deals with the maintenance policy of a system subject to periodical inspections aimed at detecting the occurrence of failures. After the
first failure, the system undergoes an imperfect repair that brings the
system back to the operating condition while the th failure is followed by a perfect repair restoring the unit to an as-good-as-new condition. The limiting average availability as well as the minimum cost policy are discussed.
