In this paper, a deteriorative repairable system consisting of a component is studied. Assume that the component after repair is not as good as new, we consider a kind of replacement policy N of the system based on the number of failures. The explicit expressions of the long-run average benefit per unit time are calculated. Under certain conditions, we prove that the policy N* is even optimal among all replacement policy. Finally, we discuss this policy by using the geometric process.
