Abstract

A series repairable system is one of the classical reliability models and is usually used in prac?tice .An optimal replacement policy for series repairable system is studied assuming that the component after repair is not “as good as new by using the geometric process model. The expressions of the long- run expected benefit and the availability per unit time are deduced. Furthermore, the replacement poli?cy model is presented with minimizing the availability rate subject to an appropriate cost rate. Lastly, a numerical example is presented, the results compared with the actual ones approve that the new mod?el is reasonable.

Key words
