Abstract:

Suppose that a device is subject to wear occurring randomly in time as a gamma process the set Xt, t or 0. Let zeta be the life length of the device. The device can be replaced before or at failure. In this paper the author gives a form of an optimal replacement policy that minimizes the expected replacement cost per unit time. Discrete version of the above results is also considered.
