Availability of a system maintained through several imperfect repairs before a replacement or a perfect repair. (English) Zbl 0968.90030
Summary: Employing the Fourier transformation technique, we find the availability of a system maintained through several imperfect repairs before a replacement or a perfect repair is allowed. We obtain exact expressions for the availability when both lifetime and repair time distributions are exponential (with possibly different parameters). Comparison is made with the system availability under the perfect repair policy.
